Abstract
A kind of symmetrical expression brake, the structural principle that it is used are：When entering compressed air in circular cylinder, piston will promote two frictional disks from the both sides of brake disc by brake disc locking, reach the purpose of braking, interaction force between the brake disc and frictional disk of this brake is often balanced, thus braking original paper is less likely to be damaged, service life is higher, also improves the functional reliability of brake to a certain extent.
Description
Technical field
A kind of symmetrical expression brake is the utility model is related to, belongs to component of machine technical field.
Background technology
Brake is the important spare part in many plant equipment, although brake structural principle is not quite similar at present,
Typically all include brake disc and frictional disk, in the course of work of braking, brake disc presses to friction in the presence of extraneous strength
Disk, so as to realize the purpose of braking, the interaction force between the brake disc and frictional disk of this brake is often inequality
Weighing apparatus, thus brake original paper and be easily damaged, service life is relatively low, also reduces the functional reliability of brake to a certain extent.
Utility model content
The purpose of this utility model is：The defects of for present in corresponding brake, the utility model provide a kind of new
Type brake, improve the service life of brake and the reliability of work.
A kind of symmetrical expression brake described in the utility model, it includes bearing cap, power transmission shaft, bearing, end cap, annular gas
Cylinder, annular piston, external toothing, frictional disk, back-moving spring, brake disc, braking body are oriented to, had among described braking body
Circular hole, and ring gear is formed with described circular hole, described braking body center section part position is formed with inside and outside identical, and several are logical
Stomata, respectively an end cap is fixed in installation at the two-port position of described braking body, has circular cylinder, institute on described end cap
The circular cylinder stated is any one in Split type structure or overall structure with end cap, and air inlet and annular gas are formed with end cap
The inside of cylinder is communicated, and an annular piston being engaged with circular cylinder is set in each circular cylinder, close to each
One guiding external toothing is set inside the brake body at individual annular piston position, external toothing is formed with described guiding external toothing,
There is the free degree in axial sliding between external toothing and ring gear, there is one on the inside of each guiding external toothing and be oriented to outer
The frictional disk of gear ring fixed-link, the structure of described frictional disk are plane or are formed with medial plane in the structure of internal conical surface
Any one, sets a back-moving spring between two guiding external toothings, and power transmission shaft is sequentially passed through among the end cap on both sides
Hole, middle endoporus, the middle endoporus of frictional disk of guiding external toothing, which are arranged on, brakes body medial axis position, and the two of power transmission shaft
End is installed together with the middle endoporus of bearing and end cap, and bearing cap is fixedly mounted on bearing outside the middle inner orifice of end cap
It is fixed, a brake disc is fixedly mounted on the power transmission shaft between two frictional disks, described brake disc both sides are planar structures
Or any one in cylindrical wimble structure.
Beneficial effect：In the utility model, when entering compressed air in circular cylinder, piston will promote two frictions
Disk by brake disc locking, reaches the purpose of braking, between the brake disc and frictional disk of this brake from the both sides of brake disc
Interaction force be often balanced, thus brake original paper and be less likely to be damaged, service life is higher, also improves to a certain extent
The functional reliability of brake.
