Any pro gram that does not call subprograms or mac ros is called the main pro gram – the only

Coupling selection method

Couplings variety, type, specifications a lot, in the correct understanding of variety, type, size, based on the concept of their own, according to the needs of the transmission to select the coupling, the first standard has been developed from the choice of coupling, The development of the international and the subject of dozens of standard coupling, the standard coupling the vast majority of general-purpose coupling, universal coupling notching machine, each coupling has its own characteristics and the scope of the basic Can meet the needs of a variety of conditions, under normal circumstances, designers do not need to design their own coupling, only in the existing standard coupling can not meet the need to design their own coupling. Standard coupling easy to buy, the price than the design of non-standard coupling to be much cheaper. In many of the standard coupling, the correct choice for their needs the best coupling steel structural drilling machine, related to mechanical products shaft drive performance, reliability, service life, vibration, noise, energy saving, transmission efficiency, transmission accuracy, Economic and a series of issues, but also related to the quality of mechanical products. Designers in the selection of coupling should be based on the perspective of the shaft drive and the need to select the coupling, should be avoided only consider the main, driven side coupling selection coupling.

hydraulic hole punch machine
First, the choice of coupling factors should be considered
(A) the mechanical characteristics of the power machine
Power machine to the work machine, through one or several different varieties and specifications of the coupling will be the main and driven side together to form a shafting transmission system. In mechanical transmission, the power machine is nothing more than motors, internal combustion engines straightening machine and gas turbines. As the working principle of the power machine and different institutions, its mechanical characteristics vary widely, and some smooth operation, and some operation when the impact of the formation of the transmission system ranging from the impact. According to the mechanical characteristics of the engine, the power machine is divided into four categories. Universal coupling, see Table 1.

Type code of power machine Name of power machine Power factor (kw)
Motors, turbines 1.0
Four cylinder and four cylinder or more internal combustion engine 1.2
Two cylinder internal combustion engine 1.4
Single cylinder internal combustion engine 1.6

The mechanical characteristics of the power machine have certain influence on the whole transmission system. For different types of power machines, due to their different mechanical properties, the appropriate power factor Kw should be selected to select the optimum coupling suitable for the system. The type of power machine is to select the basic factors of coupling varieties, the power of the power machine is to determine the size of one of the main specifications of the coupling, and the coupling torque is proportional. Fixed mechanical products Powertrain in the drive system are mostly motors, mechanical products to run the drive system (such as ships, all kinds of vehicles, etc.) in the power engine for the internal combustion engine, when the engine for the cylinder number of different internal cnc drilling machine combustion engine, must consider torsional vibration Transmission system, the impact of this factor and the internal combustion engine cylinder number, the cylinder is working properly. At this point the general should be used in flexible coupling to adjust the shaft natural frequency, reduce the torsional vibration amplitude, thereby reducing vibration, buffer, protect the transmission components, improve the performance and improve the stability of the output power.
(B) load categories
Due to the different structures and materials, the coupling capacity of the couplings used in the drive systems of the various mechanical products varies greatly. Load category is mainly for the working load of the impact of the work load, vibration, reversing, braking, frequent start and other reasons to form different types of load. To facilitate the selection of the calculation, the transmission system load is divided into four categories, see Table 2.
Table 2 Load categories

Load Category Load condition Operating factor (k)
Load evenly, work smoothly 1~1.5
Medium impact load 1.5~2.5
Heavy shock load, frequent positive and negative rotation 2.5~2.75
Special heavy impact load, frequent positive and negative rotation >2.75

The load category of the transmission system is the basis for selecting the variety of couplings. Shock, vibration and torque changes in the larger working load should be selected with flexible components that flexible coupling flexible coupling to cushion, damping, compensation axis offset, improve the transmission performance. Start frequently, forward and reverse, the torque is normal braking when the torque is several times the work is overloading work, will inevitably shorten the life of coupling elastic components, coupling only allows short-term overload, the general short-term The overload shall not exceed 2 to 3 times the nominal torque, ie [Tmax] ≥ 2 to 3T n.
Low-speed conditions should avoid the use of only suitable for small and medium-power coupling, for example: elastic sleeve pin coupling, core type flexible coupling, polygonal rubber coupling, tire-type coupling, etc .; need to control overload Safety coupling should be selected with safety coupling, and elastic drill machine coupling with elastic element and better cushioning and damping effect should be selected for shaft system with large load variation and impact and vibration. Elastic couplings have higher load-carrying capacity than non-metallic elastic couplings. Elastic couplings with elastic elements are more reliable than elastic couplings for shearing elastic elements.
(C) the allowable coupling speed
The permissible speed range of the coupling is determined by calculation based on the permissible line speed and maximum outer edge dimensions for the different materials of the coupling. Different materials and varieties, specifications of the coupler allows the speed range is not the same, change the coupling material can improve the coupling allowable speed range, material for steel permissible speed is greater than the material for the cast iron permissible speed. For n> 5000r / min working conditions of the coupling, coupling should consider the outer edge of the centrifugal force and deformation of elastic elements and other factors, and should be dynamic balance. High-speed elastic coupling should not use non-metallic elastic components, the formation of high-speed elastic deformation, should use high-precision flexible coupling, the current foreign high-speed coupling for nothing more than diaphragm coupling and High – precision drum – shaped gear coupling. Universal coupling
(D) coupling the shaft displacement relative to the two axes
The coupling of the two shafts due to manufacturing errors, assembly errors, installation errors, shaft load and deformation, deformation of the base, bearing damage, temperature changes (thermal expansion, cold shrink), the relative movement between components Relative displacement. (X), radial (y), angular (α), and displacement of the shafting under different operating conditions, and the displacement of the two axes is not easy to avoid. In general, The size varies. Only the flexible coupling has to compensate for the relative displacement of Head punching machine the performance of two axes, so a large number of practical applications in the selection of flexible couplings. Rigid coupling does not have compensation performance, the scope of application is limited, so little use. Angle (α) the only larger shafting should use universal coupling, axial movement, and the need to control the axial displacement of the shaft drive, should use diaphragm coupling; only the precision is very High selection of rigid couplings, the standard flexible coupling allowable compensation in Table 3.

Testing standard of bicycle pedal

Pedal, what is it? That is, on certain machines or parts of machinery that are designed for footing. The most common bike is. Texture is generally nylon plastic, but there are professional bicycle which is used in aluminum, magnesium alloy, etc. Foot pedal is divided into bearing and ball-type pedal Do not look at this stuff is very small, in fact, it is an equal arm lever. It is the middle of the axis is divided into two parts, the distance on both sides of the same buy drill machine, so that the human foot in the case of non-stop pedal rotation is still able to maintain a want to state before and after hard, do not adjust the foot back and forth position. Incidentally, this part is the most solid on the bike, and every time you get off the taxi, the body’s weight is pressed on top, can imagine the degree of solid foot pedal. Gear ratio: the ratio of the number of teeth of the driven wheel to the driven wheel is the gear ratio.

 

If the two gears have the same number of teeth, then pedal a week. The two gears and the rear wheels rotate one each. If the number of teeth of the driven gear is greater than the number of teeth of the driven gear, then the number of revolutions of the driven gear per revolution is greater than one week, and the speed is increased. Therefore, the gear ratio is proportional to the number of teeth of the drive wheel and inversely proportional to the number of teeth of the driven gear. G represents the gear ratio, C represents the number of gear teeth, F represents the number of passive gear teeth, the relationship between them expressed by the formula, namely: g = c / f For example: the car is 49 teeth, the flywheel is 14 teeth, into the formula can be obtained gear ratio: g = c / f = 49/14 = 3.5 In other words, pedaling a week, flywheel three and a half weeks. Transmission ratio (transmission coefficient): Gear ratio multiplied by the diameter after the ring, is the transmission ratio. D represents the gear ratio, b represents the diameter of the back circle, the relationship between them with the formula that: d = c / f × b = gb It can be seen, the gear ratio is determined, the transmission ratio is proportional to the diameter of the back ring.

For example: 49 teeth, flywheel is 14 teeth, the back ring diameter of 27 (usually used in English), generation formula can be obtained transmission ratio: D = C / F × b = 49/14 × 27 = 3.5 x 27 = 94.5 Transmission stroke, each pedaling a week, the car forward movement distance is the transmission, travel, also known as the speed ratio of travel. It is calculated by multiplying the gear ratio by the pi. Where M is the transmission stroke, π is the ratio of the circumference (this is a constant, π = 3.14), and the relationship between them is expressed by the formula. That is, M = D? = C / F? B? Bicycle rear wheel diameter measurement commonly used in English, while the trip is generally used to calculate the metric system, so in the calculation need to convert the British metric system. One hour = 2.54CM, with K to represent, namely: K = 2.54CM. Into the formula, namely: M = G / F × B × π × k For example, the car is 49 teeth angle work machine, the flywheel is 14 teeth, the true diameter of the rear wheel when the bishop of Huang cnc bending machine, seeking it distance, find it distance, generation formula: M = C / F × b × π × k = 49 / 14 x 27 x 3.14 x 2.54 = 754 cm The above data is bike pedaling a week, the car forward for 745cm, or 7.54m.

Punch works Punch design principle

Punch works Punch design principle is to convert the circular motion to linear motion. (Or eccentric gear), connecting rod and other operations, to achieve the linear motion of the slider drill angle steel, from the main motor to the movement of the connecting rod for the circular motion of the main motor to drive the flywheel, the clutch drive gear, crankshaft (or eccentric gear) Link and slide between the need for circular motion and rectilinear motion of the transfer point cnc busbar bender, the design generally has two kinds of institutions, one for the ball type, one for the pin type (cylindrical) drill machine, through this mechanism will be circular motion Into a linear motion of the slider.

Punch the ring, small parts of the role of large

Punch the ring, small parts of the role of large In this case, The sealing ring is mounted on both ends of the ball nut. Contact with the elastic seal cabinet rubber oil or nylon and other materials made of Qi punch machine for Head, the hole made with the screw thread raceway with the shape. Contact the sealed cabinet of the dustproof effect, but because of contact pressure, so that a slight increase in friction torque metal saw. Non-contact seals made of PVC and other plastics, the punch hole in the shape of screw thread with the opposite race, and a slight gap. Non-contact seal also known as labyrinth seal cnc angle machine. Sealing ring is the most indispensable member of the punch.

Classification of presses

Classification of presses 1. According to the slider drive force can be divided into two kinds of mechanical and hydraulic (1) mechanical punch (2) hydraulic presses 2 welding machine for plate. According to the slider movement classification: single-action plate beveling machine, double action, three-action, such as punching 3 Welding adjustable stand. According to the slider drive mechanism classification (1) crankshaft punch (2) without crankshaft punch (3) the toggle type punch (4) friction punch (5) spiral presses (6) rack-type presses (7) connecting rod punch (8) cam-type punch

The main rotating machine parts The main rotating machine

The main rotating machine parts The main rotating machine parts Punch the main rotating parts, fitted with connecting rod, can take up and down the connecting rod (reciprocating) into circular motion (rotation) movement. Is an important part of the punch bed. Its material is made of carbon structural steel or ductile iron. There are two important parts: the main journal, the connecting rod neck, (and others). The main journal is installed on the bed. The connecting rod neck is connected with the big head hole of the connecting rod, and the connecting rod small head hole is connected with the punching slide. It is a typical crank slider mechanism. The lubrication of the crankshaft mainly refers to the bearing between the rocker arm lubrication and two fixed-point lubrication Metal Marking Machines. The rotation of the crankshaft is the power source of the press. But also the source of the entire mechanical system.
