Abstract
The invention discloses a pneumatic clutch which comprises a bracket consisting of a bracket shaft and a bracket base. The bracket shaft is sleeved with a first bearing; the first bearing is sleeved with a belt pulley; a friction plate is fixedly arranged on the belt pulley; the other side of the friction pulley is contacted with a driven pulley; the driven pulley is fixedly connected with a movable block; the bracket shaft is also sleeved with a key sleeve bearing; the key sleeve bearing is sleeved with a splined sleeve; one end of the splined sleeve is sleeved with a spring, and the other end of the splined sleeve is sleeved with the driven pulley; the end part of the bracket shaft is provided with a sealed air faucet; and the pneumatic clutch is characterized in that: the sealed air faucet is a graphite sealed air faucet. The pneumatic clutch with the structure has a long service life and is difficult to produce noise.
Description
Technical field
The present invention relates to a kind of clutch, be particularly useful for a kind of pneumatic clutch.
Background technique
Clutch is mechanically common mechanism, its function mainly be by friction plate from whether exporting with incompatible control mechanokinetic, usually by the form that acts on the axial force on the friction plate can be divided into the hand lever formula, the formula of surging and pneumatic type.Pneumatic clutch be exactly utilize fluid by cylinder, utilize pressurized air realizes friction plate as the mode of power axial engagement and separate.
Pneumatic clutch on the market mainly comprises the support that is made of support shaft and bracket base at present, belt pulley, follower and movable block, support shaft is connected with belt pulley by the belt pulley bearing, belt pulley is provided with friction plate, the opposite side of friction plate contacts with follower, the other end of follower is fixedlyed connected with movable block by screw, and on support shaft, also be set with key cover bearing, be set with spline housing on the key cover bearing, one end of spline housing is set with spring, the other end is set with follower, the end of support shaft is provided with a sealing valve, though this kind pneumatic clutch compact structure, easy to use, but, easily produce noise because thereby the sealing valve is made easy to wearly for the common metal material.
Summary of the invention
Technical problem to be solved by this invention provides a kind of long service life, and is difficult for producing the pneumatic clutch of noise.
For realizing above purpose, technical solution of the present invention is:
A kind of pneumatic clutch, comprise the support that constitutes by support shaft and bracket base, be set with clutch shaft bearing on this support shaft, be set with belt pulley on this clutch shaft bearing, be set with friction plate on this belt pulley, the opposite side of friction plate contacts with follower, follower is fixedlyed connected with movable block, also be set with key cover bearing on the described support shaft, be set with spline housing on the key cover bearing, one end of spline housing is set with spring, the other end is set with follower, and the end of described support shaft is provided with a sealing valve, and it is characterized in that: described sealing valve is the graphite grazing valve.
One end of described sealing valve is fixedlyed connected with support shaft by the valve set screw nut.
One end of described spring is provided with jump ring, and the other end contacts with an end of follower by pad, and described jump ring and pad all are sleeved on the outer surface of an end of spline housing.
Compared with prior art, beneficial effect of the present invention is:
Because a kind of pneumatic clutch of the present invention adopts the graphite grazing valve, because graphite has the function of sub-selflubricating, thereby make the sealing valve be difficult for wearing and tearing, so the life-span of the present invention is long, and is difficult for producing noise.
Description of drawings
Fig. 1 is the sectional view of disclosed pneumatic clutch.
Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further details:
As shown in Figure 1, a kind of pneumatic clutch, comprise the support 1, belt pulley 2, the follower 3 and movable block 4 that constitute by support shaft and bracket base 11, support shaft is made of one 12 on support, two 13 on support and support termination 14, base 11 is a claw-like, and one 12 on support, two 13 on support and support termination 14 are cylinder type.Be set with clutch shaft bearing 5 on one 12 on the support; be set with belt pulley 2 on the outer surface of clutch shaft bearing 5; the side of belt pulley 2 contacts with friction plate 6; the opposite side of friction plate 6 contacts with follower 3; the other end of follower 3 is connected with movable block 4 by screw 7; be provided with seal ring 15 with movable block 4 contacted positions on the inboard of the other end of follower 3, the position of nearly movable block 4 is provided with projection protection piece 16 on the outside.Be set with key cover bearing 8 on two 13 on the support, be set with spline housing 9 on the key cover bearing 8, an end of spline housing 9 is set with spring 10, and the other end is set with follower 3.Match with the cavity of movable block 4 inside in support termination 14.
The inside of an end that is connected with support termination 14 on two 13 on the support is provided with sealing valve 17, sealing valve 17 is made by graphite material, one end of sealing valve 17 is fixedlyed connected by the outer surface of an end of two 13 on valve set screw nut 18 and support, the other end communicates with horizontal air flue 19, the other end of horizontal air flue 19 communicates with vertical air flue 20 in being arranged on base 11, and vertically the other end of air flue 20 is connected with air inlet nut 21.
Key cover bearing 8 is connected with belt pulley bearing 5 by fixed block 22, and fixed block 22 is sleeved on two 13.
One end of spring 10 is provided with jump ring 23, and the other end contacts with an end of follower 3 by pad 24, and described spring 10 is the ripple spring, and described jump ring 23 and pad 24 all are sleeved on the outer surface of an end of spline housing 9.
The present invention is long service life not only, and is difficult for producing noise.
The above only is a better embodiment of the present invention; protection scope of the present invention is not exceeded with above-mentioned mode of execution; as long as the equivalence that those of ordinary skills do according to disclosed content is modified or changed, all should include in the protection domain of putting down in writing in claims.
