Abstract
The utility model relates to an axial pneumatic clutch which is composed of a belt pulley, a friction plate, a driving and reversing disk, an elastic air chamber, a reset spring, an output shaft, etc. The axial pneumatic clutch is characterized in that the output shaft 16 is an input shaft of a gearbox or a working machine, and an air inlet passage 1 in a pneumatic mechanism uses the elastic air chamber composed of an elastic membrane 3, a seal disk 4, etc. to replace an original air cylinder in the seal disk 4, so that the axial dimension of a clutch is decreased, and the structure of the clutch is simple. The output shaft is directly composed of subordinate machines such as the input shaft of the gearbox or the working machine, so that a shaft coupling does not need to be arranged between the output shaft of the clutch and the input shaft of the subordinate machines. The axial pneumatic clutch has novel structure and low cost.
Description
The utility model is a kind of clutch that utilizes pneumatic element control friction plate clutch.
Clutch is mechanically common mechanism, its function mainly be by friction plate from whether exporting with incompatible control mechanokinetic.Usually divide by the pattern that acts on the axial force on the friction plate, the hand lever formula is arranged, the formula of surging and pneumatic type.Wherein, the hand lever formula is a kind of more common structural type, be difficult for to realize automation, and its main functional part friction plate needs frequent adjusting play, uses cumbersomely, is used for therefore that some are simply mechanical more; Surge with pneumatic type clutch utilize fluid by cylinder or oil cylinder control friction plate from close, mechanism is huge, especially the axial dimension of clutch is quite big, but cylinder and oil cylinder are controlled by electrical system, easy to operate, easily be automated, between the input shaft of the output shaft of clutch and gearbox or work mechanism shaft coupling must be arranged, power consumption is big.
The purpose of this utility model is the novel pneumatic clutch of a kind of compactness rational in infrastructure of design.
Its technological scheme is need not specialized designs output shaft 16 in clutch, utilize subordinate's machinery to make output shaft as the input shaft of work mechanism or gearbox, omit a shaft coupling, an air chamber 7 that is made of elastic membrane 3 or elastic membrane 3 and seal disc 4 is arranged in the clutch, gas-entered passageway 1 is arranged in seal disc 4, after the gas with certain pressure enters air chamber 7, elastic membrane 3 expands, promote the advance and retreat disk 9 adjacent with elastic membrane 3, compression reseting spring 15, advance and retreat disk 9 and telophragma 11 are closely contacted with friction plate 10, friction plate 10 shapes such as involute gear, and with ring gear 8 engagement that has internal tooth, ring gear 8 is fixed on the belt pulley 6, therefore friction plate 10 changes with belt pulley 6, advance and retreat disk 9 and telophragma 11 are the internal spline structure, and match with spline on the shell dish 12, shell dish 12 and output shaft 16 cooperate with flat key, their threes can move axially each other, but can not rotate, when advance and retreat disk 9 and telophragma 11 closely contact with friction plate 10, effect because of friction torque, output shaft 16 is also moving thereupon, the machine power of belt pulley 6 just can be by output shaft 16 defeated postals, go out when the solenoid valve that open the control source of the gas, when air chamber 7 was communicated with atmosphere, elastic membrane 3 was just shunk, advance and retreat disk 9 and telophragma 11 reset under Returnning spring 15 effects, advance and retreat disk 9 and telophragma 11 is because disappear and stop operating with the frictional force of friction plate 10 is short, and the defeated shaft 16 of posting also stops thereupon, makes the power of belt pulley can not be by output shaft 16 outputs.
The utility model has the advantages that and utilize a flexible air chamber to substitute original cylinder, low cost of manufacture, simple in structure, the axial dimension of clutch significantly reduces; Utilize in addition elastic film control friction plate from close, the gap of friction plate need not often be adjusted, and is easy to use; Output shaft is directly used the input shaft of gearbox or work mechanism, omits shaft coupling, and kinetic equation loss is economized, and mechanism is simple.
Fig. 1 is the structural drawing of clutch, and the outer gland 5 of air film plays fixedly elastic membrane 3 with air film internal gland 2 among the figure.11 of Returnning spring 15 and advance and retreat disk 9 and telophragmas have a spring seat 14, and Returnning spring 15 is installed on the shell dish 12.Output shaft 16 directly utilizes the input shaft of work mechanism or gearbox, between the input shaft of the output shaft of clutch and gearbox etc., need not coupling, the parts such as supporting plate that on clutch, also need not to be installed as the supporting output shaft and design, make structure obtain simplifying, also reduced the loss of power in transmission course simultaneously.
Claims (3)
1, a kind of pneumatic clutch is made up of power input mechanism, power take-off mechanism, pneumatic mechanism etc., it is characterized in that output shaft 16 is exactly the input shaft of gearbox or work mechanism, and the gas-entered passageway 1 in the pneumatic mechanism is in seal disc 4.
2, clutch according to claim 1, one side what it is characterized in that air chamber 7 is elastic membrane 3, another side is a metal sealing disk 4.
3, clutch according to claim 1 is characterized in that air chamber 7 is made of the elastic membrane 3 of shape such as air tube.
