Removal device for retaining ring of train hub bearing

Abstract

The invention provides a train hub bearing retaining ring removal device, which includes a wheel. A wheel bearing is arranged between the wheel and an axle, a bearing retaining ring is arranged on theouter side of the wheel bearing, circular grooves are symmetrically formed in the bearing retaining ring, the bearing retaining ring can be connected and matched with one end of an inserting rod in an inserted mode, and the other end of the inserting rod is connected with connecting plates; a telescopic rod is arranged between the two connecting plates, the two ends of the telescopic rod are fixedly connected with the connecting rods on the corresponding sides correspondingly, and the other ends of the connecting rods are fixedly connected with sliding blocks; and the two sliding blocks are located in a sliding groove formed in a rotating plate, baffles are arranged on the upper side and the lower side of the sliding groove correspondingly, the widths of the sliding blocks are greater than the distance between the two baffles, an electric drill connector is arranged in the center of the side, away from a connecting rod, of the rotating plate, and the electric drill connector can fix the drill pipe end of an electric drill. According to the train hub bearing retaining ring removal device, the bearing retaining ring can be conveniently and rapidly removed through the electric drill,and use is convenient; and meanwhile, the conditions that rusting, gaps are blocked due to salt deposition or the bearing retaining ring is frozen due to the cold weather can be conveniently and rapidly handled, and the bearing retaining ring is conveniently removed.

Problems solved by technology

In order to ensure the normal operation of the train, it is necessary to regularly maintain and clean the bearings of the train, and at the same time replace the faulty bearings. When removing the bearings, you need to remove the bearing retaining ring first. The bearing retaining ring is located in the groove of the wheel. Inside, it is difficult to use tools to cooperate with it. At the same time, for the safety of train operation, the bearing retaining ring is fixed relatively firmly. It is difficult to remove it only by manpower. At the same time, the train is running all over the world every day. , easy to rust, block with salt, or freeze the bearing retaining ring due to cold weather, which increases the difficulty of removing the bearing retaining ring, and in the above cases, it is easy to damage the structure of the bearing retaining ring if the bearing retaining ring is removed forcibly. make it unusable again
