Abstract
The utility model discloses an impeller type active lubrication brake cylinder, which comprises a brake cylinder body, and a piston arranged in the brake cylinder body, wherein a rotating impeller is arranged at the bottom of the piston, a plurality of blades with a certain inclination angle are arranged on the impeller, vents in the brake cylinder body right face to the blades of the impeller, a plurality of oil scraping pieces are arranged on the periphery of the impeller, and the ends of the oil scrapping pieces are tightly bonded with the inner wall of the brake cylinder body. According to the impeller type active lubrication brake cylinder, the rotating impeller is additionally arranged at the bottom of the piston, when air enters into the brake cylinder, the pressure air can push the impeller to rotate at a certain angle, so that after circulation for many times, lubricating grease, which is fallen to the bottom of the brake cylinder is smeared to the upper part of the brake cylinder through the oil scraping pieces on the impeller, thus a rubber sealing ring is lubricated in a using process of the brake cylinder.
Description
Technical field
The utility model relates to a kind of impeller type and initiatively lubricates master cylinder.
Background technique
Rail wagon brake cylinder (similar general cylinder) is generally horizontal installation, in piston rubber seal, lubricating grease is thinning in summer high temperature situation, because gravity and Vehicular vibration flow pendant naturally to master cylinder bottom, and top lacks lubricating grease, seal ring and casing wall dry friction increase frictional force greatly, cause the easy flange of seal ring, master cylinder is revealed, and affects traffic safety.
Model utility content
Goal of the invention of the present utility model is: for the problem of above-mentioned existence, provide a kind of and stream pendant can be spread upon to master cylinder top by the lubricating grease in master cylinder bottom, thereby make master cylinder in use, rubber seal obtains lubricated impeller type and initiatively lubricates master cylinder.
The technical solution of the utility model is achieved in that a kind of impeller type initiatively lubricates master cylinder, comprise brake cylinder casing and be arranged on the piston in brake cylinder casing, it is characterized in that: in the bottom of described piston, be provided with rotatable impeller, on described impeller, be provided with some blades with certain angle of inclination, vent on described brake cylinder casing is over against the blade of impeller, in described impeller periphery, be provided with some oil-scrapping sheets, described oil-scrapping sheet end and brake cylinder casing inwall fit tightly.
Impeller type described in the utility model initiatively lubricates master cylinder, and described in it, the bottom of piston is provided with boss, at the center of described impeller, has through hole, and described impeller is socketed in axle on the boss of piston base and centered by it and rotates by through hole.
Impeller type described in the utility model initiatively lubricates master cylinder, and its some blades are centered by the axle center of impeller, be radially evenly distributed on same circumference along it, and the direction of described some blade leans and angle are all consistent.
Impeller type described in the utility model initiatively lubricates master cylinder, described in it, some oil-scrapping sheets one end is connected with impeller periphery and is uniformly distributed, its the other end is along the radial direction perk of impeller, and the perk of described oil-scrapping sheet part fits tightly with brake cylinder casing inwall after contacting and produce certain deformation with brake cylinder casing inwall.
Impeller type described in the utility model initiatively lubricates master cylinder, and its raised head face in described piston base is provided with impeller back-up ring, and described impeller is arranged between impeller back-up ring and piston base, between described impeller back-up ring and impeller, has certain interval.
The utility model is by increasing rotating impeller in piston base, when master cylinder air inlet, pressure air can promote vane rotary several angle, like this, after repeatedly circulating, the oil-scrapping sheet being arranged on impeller can be applied to master cylinder top by the lubricating grease in master cylinder bottom by stream pendant, thereby makes master cylinder in use, and rubber seal is lubricated.
Accompanying drawing explanation
