Abstract
Disclosed is a pneumatic brake device, which is characterized by comprising a brake rod, a lower end cover, a casing, a rubber sleeve, an upper end cover and an air inlet nozzle. Two ends of the casing are respectively connected with the lower end cover and the upper end cover, both the lower end cover and the upper end cover are equipped with center holes, the rubber sleeve coaxial to the center holes of the end covers is arranged inside the casing, two ends of the rubber sleeve are in sealing contact with edges of the center holes on the inner sides of the end covers, a chamber is arranged between the outer side of the rubber sleeve and the inner side of the casing, one side of the casing is equipped with the air inlet nozzle. The utility model has the advantages of simple structure, reliable operation, fine brake flexibility, low damage to shafts and being easy to be controlled and implemented.
Description
Technical field
The utility model relates to a kind of pneumatic braking system, and the distortion by the inner elastomeric element realizes moving axially the purpose that axle is braked, and is adapted at the little occasion of active force and uses.For example: the braking of glass edge-grinding machine polishing wheel is exactly to have adopted this kind air-actuated band brake braking device.
Background technique
Rolling brake to rotatingshaft in the prior art generally adopts mechanical brake equipment, and as the surface friction with the friction brake wafer countershaft, friction infringement and severity of braking are all bigger, are unsuitable for flexible damping brake.
Summary of the invention
The purpose of this utility model just provides a kind of pneumatic braking system, and is all bigger with wear evil and the severity of braking that solves that prior art exists, and is unsuitable for the problem of the damping brake of flexibility.
The technical solution of the utility model is: comprise brake rod, lower end cap, housing, rubber sleeve, upper end cap and air inlet nozzle, the two ends of housing connect lower end cap and upper end cap respectively, on lower end cap and upper end cap, be equipped with center hole, rubber sleeve with the center hole concentric of described end cap is housed in this housing, the two ends of this rubber sleeve contact with the center hole edge sealing of described end cap inboard, are provided with chamber between the inboard of this rubber sleeve outside and housing; Side at described housing is provided with air inlet nozzle, and described brake rod slides and passes the center hole of lower end cap, upper end cap and rubber sleeve.
Be provided with the footpath outward flange at the two ends of described rubber sleeve, this outward flange sealing is installed between the respective slot and lower end cap and upper end cap inboard of inboard, described housing two ends.
Outward flange both sides at the two ends of described rubber sleeve are provided with bulge loop or scrobicular ring; Be provided with scrobicular ring or bulge loop that bulge loop or scrobicular ring with these rubber sleeve two ends coincide in the groove at described housing two ends and described lower end cap and upper end cap inboard.
Described air inlet nozzle is fixed by air inlet nozzle set screw and described housing.
Be provided with the twill annular knurl on the surface of described brake rod.
The utility model has the advantages that: simple in structure, reliable operation, braking is flexible good, and is little to the damage of axle, controls easily and implements.
