Abstract
The invention discloses a pneumatic clutch, which comprises a transmission shaft. A flywheel, a driven shaft sleeve, a driving disc and a shell are sequentially sleeved at one end of the transmission shaft. The driven shaft sleeve is fixedly connected with the transmission shaft. A plurality of movable friction shoes are embedded into an outer circle of the driven shaft sleeve. The driving disc is idly sleeved on the transmission shaft, and is connected with the shell in circumferentially fixed and axially movable ways through a plurality of transmission pins. A plurality of springs capable of enabling the driving disc to tend to get close to the shell are sleeved on the transmission pins. The driving disc is in sliding connection with the shell through the nesting of concave and convex ring structures to form a ring-shaped cylinder cavity between the driving disc and the shell. The ring-shaped cylinder cavity is communicated with an air vent in the center of the shell, and is sealed through an inner side sealing ring and an outside sealing ring, which are arranged between the driving disc and the shell. The shell is arranged on the transmission shaft through a bearing B, and is fixedly connected with the flywheel. The technical scheme is simple in structure and reliable in transmission torque, the inertia of the flywheel is improved, the transmission accuracy is improved, and the service life is prolonged.
Description
Technical field
The present invention relates to a kind of with rotating power source to the device that work mechanism transmits, relate in particular to a kind of pneumatic clutch.
Background technique
The mechanical press Clutch and brake is arranged at bent axle together near on flywheel one end at present, and patent No. ZL99805307.4 discloses a kind of mechanical press clutch brake apparatus; The Clutch and brake of this mechanical press clutch brake apparatus joins together and is arranged at bent axle near on flywheel one end, because joining together, Clutch and brake is arranged at bent axle near on flywheel one end, make crankshaft two end be subjected to force unbalance, make crankshaft support spare, easily lost efficacy such as bearing, reduction of service life, and affect the press machine operating accuracy.When this mechanical press clutch brake apparatus is used for high-speed mechanical press machine, its deficiency is even more serious, this mechanical press clutch brake apparatus adopts the oil hydraulic cylinder switching mechanism that Clutch and brake is switched, complex structure, and easily produce seepage.And existing clutch exists complex structure, spatial requirement large (placing outside the flywheel), the large defectives such as (clutch mainly place on the transmission shaft) of braking inertia.
Summary of the invention
In order to solve above-mentioned technical problem, the purpose of this invention is to provide a kind of pneumatic clutch, the structural design that adopts Clutch and brake to separate adopts pneumatic control, simple in structure, carry-over moment is reliable, and overload operation safety increases flywheel inertia (housing and flywheel rotate simultaneously), compressed air delivery is simple and reliable, the cylinder of the approximate sealing of housing, good airproof performance, the transmitting accuracy and the working life that are conducive to improve pneumatic clutch.
To achieve the above object, the present invention has adopted following technological scheme:
Pneumatic clutch, comprise transmission shaft, one end of described transmission shaft is arranged with flywheel successively, driven axle sleeve, driving disc and housing, flywheel is installed on the transmission shaft by bearing A, driven axle sleeve is fixedly connected with transmission shaft, be inlaid with a plurality of removable brake pads on the outer ring of driven axle sleeve, the driving disc empty set on transmission shaft and by a plurality of driving pins with circumferentially fixing be connected the mode that can move and be connected with housing, be arranged with a plurality of springs that can give the close housing trend of driving disc on the driving pin, thereby between driving disc and housing, consist of the ring-type cylinder chamber by nested being slidingly connected of concavo-convex ring structure between driving disc and the housing, this ring-type cylinder chamber is communicated with the vent that is located at the housing center, this ring-type cylinder chamber is by being located at inner seal ring and the outside seal ring seal between driving disc and the housing, and housing is installed on the transmission shaft and with flywheel by bearing B and is fixedly connected with.
The present invention has been owing to having adopted above technological scheme, and the structural design that adopts Clutch and brake to separate makes that the transmission shaft two ends are stressed tends to balance; The clutch volume is little, lightweight, moves more sensitively, in the working life of having improved cardan-shaft suspension spare, has improved the operating accuracy of high-speed mechanical press machine; Adopt pneumatic control, simple in structure, carry-over moment is reliable, overload operation safety increases flywheel inertia (housing and flywheel rotate simultaneously), and compressed air delivery is simple and reliable, the cylinder of the approximate sealing of housing, good airproof performance, the transmitting accuracy and the working life that are conducive to improve pneumatic clutch.

Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is made a detailed explanation.
Embodiment 1:
Pneumatic clutch as shown in Figure 1, comprise transmission shaft 1, one end of described transmission shaft 1 is arranged with flywheel 3 successively, driven axle sleeve 6, driving disc 4 and housing 7, flywheel 3 is installed on the transmission shaft 1 by bearing A2, driven axle sleeve 6 is fixedly connected with transmission shaft 1, as shown in Figure 2, be inlaid with 6 removable brake pads 5 on the outer ring of driven axle sleeve 6, driving disc 4 empty sets on transmission shaft 1 and by a plurality of driving pins 9 with circumferentially fixing be connected the mode that can move and be connected with housing 7, be arranged with a plurality of springs 10 that can give driving disc 4 close housing 7 trend on the driving pin 9, thereby between driving disc 4 and housing 7, consist of the ring-type cylinder chamber by nested being slidingly connected of concavo-convex ring structure between driving disc 4 and the housing 7, this ring-type cylinder chamber is communicated with the vent 71 that is located at housing 7 centers, this ring-type cylinder chamber is by being located at inner seal ring 11 and 12 sealings of outside seal ring between driving disc 4 and the housing 7, and housing 7 is installed on the transmission shaft 1 and with flywheel 3 by bearing B8 and is fixedly connected with.
When the vent 71 obstructed pressurized gas on the housing 7, thereby owing to the tension force of spring 10 separates near housings 7 driving disc 4 with driven axle sleeve 6, so that the rotating power of flywheel 3 can not be delivered to driven axle sleeve 6.When the vent 71 on the housing 7 passes into pressurized gas, when pressurized air enters the circular cylinder chamber, promotion driving disc 4 overcomes spring force and moves the mobile brake pad 5 of inlaying in the driven axle sleeve 6 of compression, so that between the driving disc 4, driven axle sleeve 6, flywheel 3 threes by mobile brake pad 5 synchronous rotations bonded to each other, thereby realize the transmission of power source.When compressed gas source stops, driving disc 4 retracts by the tension force of housing 7 interior Compress Springs, decontrols the compression to mobile brake pad 5, becomes free separated position between driving disc 4, driven axle sleeve 6, flywheel 3 threes, realizes the disengaging of power source.
