Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As depicted in figs. 1 and 2, a kind of novel pneumatic brake, including main shaft 1, axle sleeve 2, driving disk 3, mobile disk 4
With cylinder body 5；Axle sleeve 2 is set on the main shaft 1；Driving disk 3, mobile disk 4 and cylinder body 5 are sequentially sleeved on axle sleeve 2, and
Driving disk 3 is rotatably connected on axle sleeve 2 by bearing 6, because of bearing 6, so that the driving rotation of disk 3 is more smooth；It is mobile
Disk 4 and axle sleeve 2 are slidably connected, and in the present embodiment, mobile disk 4 connects the mobile circle of realization by spline with axle sleeve 2
Being slidably connected between disk 4 and axle sleeve 2, specifically, mobile disk 4 are equipped with internal spline, and axle sleeve 2 is equipped with and internal spline is matched
Close the external splines of connection；It is equipped with a cavity 51 in cylinder body 5, further includes the piston 52 being located in cavity 51, piston 52 and cylinder body 5
Between formed sealed chamber 53, it should be noted that piston 52 can not be filled up completely completely entire cavity 51, thus piston 52 and cylinder body
Sealed chamber 53 is formed between 5, sealed chamber 53 is also to belong to a part of cavity 51, with when being discharged into high pressure gas to sealed chamber 53 into
And drivig cylinder 5 moves downward that mobile disk 4 is driven to move, thus so that mobile disk 4 and driving disk 3 is frictionally engaged and
Braking is realized, even if the driving disk 3 of rotation stops or reduce revolving speed.
Piston 52 is equipped with the through-hole 522 that is connected to sealed chamber 53, can be discharged by through-hole 522 to sealed chamber 53 or
High pressure gas is discharged.It further include connector 7 and flow control valve, connector 7 and through-hole 522 connect, and flow control valve passes through appendix
It is connected to connector 7, the flow that high pressure gas enters sealed chamber 53 can be can control by adjusting flow control valve.
It further include air pump, air pump is connected to also by appendix with flow control valve, and then according to actual needs to sealed chamber
53 are discharged into or are discharged high pressure gas.
Further include elastic element, elastic element is set on axle sleeve 2, the both ends of elastic element respectively with bearing 6 and mobile
Disk 4 offsets.When being discharged into high pressure gas to sealed chamber 53, cylinder body 5 moves downward that mobile disk 4 is driven to move, thus
So that mobile disk 4 and driving disk 3 is frictionally engaged and realize braking, elastic element is compressed in this process, when will be airtight
When high pressure gas discharge in room 53, the atmospheric pressure in sealed chamber 53 is reduced, and compressed elastic element is in order to restore to the original state
To generate active force to mobile disk 4, so that mobile disk 4 be made to slide to the right and separate with driving disk 3, i.e., brake is
Relieving state.In the present embodiment, elastic element is resetting spring 8.
The sealing ring 521 that 52 periphery of piston is equipped with and 51 inner wall of cavity is in close contact avoids gas to play sealing function
53 gas leakage of secret room and effect when influencing brake.In the present embodiment, sealing ring 521 is plastic cement sealing ring.
Mobile disk 4 and the side for driving disk 3 opposite are equipped with friction plate 41, i.e., in braking on mobile disk 4
Friction plate 41 and driving disk 3 are frictionally engaged, and friction plate 41 is fixedly connected with mobile disk 4, can be realized using countersunk head screw
The fixation of friction plate 41 and mobile disk 4, thus it is convenient for disassembly and assembly and meanwhile the surface of mobile disk 4 will not be made not smooth enough and can shadow
Ring the contact of cylinder body with mobile disk 4.
Thrust ball bearing 9 is equipped between cylinder body 5 and axle sleeve 2, which supports cylinder body 5, and thrust ball bearing 9 is left
Right two sides offset with mobile disk 4 and cylinder body 5 respectively.It also is provided with thrust ball bearing 9 between piston 52 and axle sleeve 2, is arranged on axle sleeve 2
There is the snap-gauge 21 for block piston 52 and thrust ball bearing 9, snap-gauge 21 fixes on axle sleeve 2, avoids piston 52 and thrust ball
Bearing 9 moves right or makes piston 52 and thrust ball bearing 9 to shake and shadow because of the effect of power in brake operation
Ring brake operation effect；The thrust ball bearing 9 supports piston 52, and the left and right sides of thrust ball bearing 9 respectively with piston 52 and
Snap-gauge 21 offsets.Thrust ball bearing 9 can bear axial load, thus thrust ball bearing 9 is not in brake or relieving
It can be because being had an impact by axial load to it.
The first retaining ring 22 for fastening snap-gauge 21 is arranged on axle sleeve 2, the first retaining ring 22 further carries out snap-gauge 21
It fixes to play the role of double shield；The second retaining ring 23 for fastening bearing 6 is arranged on axle sleeve 2, also to avoid axis
Hold 6 in the axial direction movement so that friction plate 41 and driving disk 3 on mobile disk 4 can be gone on smoothly when being frictionally engaged,
It will not be moved downward in the axial direction because of bearing 6 and influence braking effect.
Above-mentioned, bearing 6 is deep groove ball bearing.
Above embodiment only indicates that rather than limits the utility model, therefore all according to the utility model patent application
The equivalent change or modification that method described in range is done, is included in the scope of the utility model patent application.
