Abstract
The invention discloses a clutch brake which comprises a brake body and a clutch body. The brake body is formed by a brake disc, a friction plate and an air cylinder, and the friction plate is of a multi-plate type structure; the clutch body comprises a clutch piston and a clutch spring, the brake body and the clutch body are under a tight fit state, a seal is arranged between the clutch piston and the air cylinder, a fixed pin is installed on the clutch body, one end of the fixed pin is connected to the clutch piston, and accordingly the clutch piston can axially move relative to the fixed pin. The clutch brake has the advantages that a traditional single-layer friction plate type clutch brake is changed to a clutch brake of a multilayered and multi-plate type structure, and the problem that due to abrasion of friction plates, the braking effect is poor can be effectively prevented; compared with a traditional friction plate of a single-layer structure, braking torque generated when the clutch brake operates can be increased because of the multi-plate type structure, and therefore the braking effect is improved fundamentally.
Description
Technical field
The present invention relates to a kind of mechanical fitting, especially a kind of universal clutch brake.
Background technique
The development of science and technology be unable to do without renewal and the upgrading of equipment,, and for machinery, the quality of Safety performance has directly determined the market of machinery, at present in some heavy mechanical equipments for safety, all installed clutch brake in the above additional, the running of control apparatus at any time with stop.Air disc friction brake is a kind of component of machine that transmits clutch moment in various machinery and realize driven member braking that is applied to.Conventional air clutch break mainly comprises now: cylinder, brake disc and clutch wheel; Cylinder and brake disc are made and are integrally formed break cylinder; Being connected by fastening screw trip bolt of break cylinder and clutch body; In clutch cylinder, be provided with piston, between piston and break cylinder, be useful on compressed-air actuated exterior seal ring and the inner seal ring in sealing cylinder, such structure makes the braking moment of pneumatic clutch or the clutch moment can be less than normal, and under some operating modes, potential safety hazard is more serious.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of clutch brake is provided, solved clutch brake of the prior art because braking moment and clutch moment are compared with the more serious problem of the little potential safety hazard causing.
For achieving the above object, technological scheme of the present invention is:
Clutch brake, comprises brake and clutch body, and described brake is made up of brake disc, friction plate and cylinder, and described friction plate is multidisc structure; Described clutch body comprises clutch plunger and brake spring, it between brake and clutch body, is drive fit state, between described clutch plunger and cylinder, be provided with sealing, fixing pin is installed in clutch body, one end of fixing pin is connected on clutch plunger, makes clutch plunger do axial motion with respect to fixing pin.
Preferably, described friction plate is by 3～5 compressed multidisc structures that form of friction plate.
The friction plate of traditional clutch brake is single layer structure, such structure reduces the braking moment in the time of clutch brake greatly, reduce the effect of braking, and braking often later because the wearing and tearing of friction plate also can reduce braking effect, the friction plate of the clutch brake that this programme provides is multidisc, except can reducing the degree of wear of braking plate, the more important thing is the moment while greatly having improved braking, improve braking effect.
Preferably, between described clutch body and brake, form drive fit state by pin for suppressing metal.
Preferably, being sealed between described clutch plunger and cylinder has the double sealing structure of exterior seal ring and inner seal ring.
The double sealing structure that employing has exterior seal ring and inner seal ring is mainly for the sealing in clutch brake to pressurized air, prevents the braking that causes because of gas leakage hidden danger not in time.
The invention has the beneficial effects as follows: the clutch brake of traditional individual layer friction disk type is changed into the multidisc with multi-layer structure, can effectively prevent the not good problem of braking effect causing because of the wearing and tearing of friction plate; Compared with the friction plate of traditional single layer structure, the structure of multidisc can increase the braking moment of clutch brake in the time of work, thereby has fundamentally improved braking effect.
Accompanying drawing explanation
Fig. 1 is whole-cutaway view of the present invention.
In figure: brake 1, brake disc 11, friction plate 12, cylinder 13, clutch body 2, clutch plunger 21, brake spring 22, fixing pin 3, pin for suppressing metal 4, exterior seal ring 51, inner seal ring 52.
Embodiment
Below in conjunction with accompanying drawing, and in conjunction with the embodiments, the present invention is described further.
Embodiment:
As shown in Figure 1, clutch brake, comprises brake 1 and clutch body 2, and described brake 1 is made up of brake disc 11, friction plate 12 and cylinder 13, and described friction plate 12 is multidisc structure; Described clutch body 2 comprises clutch plunger 21 and brake spring 22, between brake 1 and clutch body 2, it is drive fit state, between described clutch plunger 21 and cylinder 13, be provided with sealing, fixing pin 3 is installed in clutch body 2, one end of fixing pin 3 is connected on clutch plunger 21, makes clutch plunger 21 do axial motion with respect to fixing pin 3.
As preferred version, described friction plate 12 is by 3～5 compressed multidisc structures that form of friction plate.
As preferred version, between described clutch body 2 and brake 1, form drive fit state by pin for suppressing metal 4.
As preferred version, being sealed between described clutch plunger 21 and cylinder 13 has the double sealing structure of exterior seal ring 51 and inner seal ring 52.
Workflow of the present invention is: pressurized air enters in cylinder 13 from the source of the gas inlet opening of clutch brake, under compressed-air actuated effect, clutch plunger 21 moves reciprocatingly, clutch plunger 21 does work to fixing pin 3, the elastic force that promotion fixing pin 3 overcomes brake spring 22 moves right, compress the friction plate 12 of multidisc, realize clutch and discharge; In the time that cylinder 13 compressed airs are discharged, due to the elastic force effect of brake spring 22, clutch plunger 21 is moved to the left, and pulls fixing pin 3, and the friction plate 12 of multidisc is released, realizes braking process.
The present invention compared with prior art, change the structure of original pneumatic clutch, friction plate is set to have the brake strip group structure of multi-disc friction sheet, braking moment and the clutch moment of clutch brake under braking condition is all increased exponentially, the braking, the disengaging performance that have improved clutch brake, reduced potential safety hazard.
