Gearbox bearing

Abstract

The invention discloses a gearbox bearing which comprises gear rings, bearing inner rings and two rows of rollers. The gear rings are arranged on the bearing inner rings in a sleeving mode; first roller paths are formed in the inner circumferential walls of the gear rings; second roller paths are formed in the outer circumferential walls of the bearing inner rings; the first roller paths and the second roller paths are combined to form roller cavities allowing the two rows of rollers to roll; gear teeth used for being meshed with external parts are arranged on the peripheral walls of the gearrings; oil supplementing pipelines used for supplying oil to the surfaces of the rollers are arranged in the gear rings; annular grooves are formed in the side walls of the gear rings; oil supplementing rings used for supplying oil to the oil supplementing pipelines are inserted into the annular grooves; and fixing pieces for fixing the oil supplementing rings in the annular grooves are arranged on the peripheral walls of the gear rings. The gearbox bearing provided by the invention solves the problems that in the prior art, the connecting strength between a gear and a bearing is too low, andthe friction loss of the rollers is increased due to lean oil.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a gearbox bearing. Background technique [0002] The gearbox bearings in the prior art are usually combined by plugging the gear and the bearing, and the gear is sleeved on the outer ring of the bearing, but this combination will reduce the connection strength between the gear and the bearing, making the gear and the bearing The friction loss between the bearings increases, resulting in a decrease in the service life of the bearings, and the installation process between the bearings and the gears is more troublesome, and the machining accuracy is relatively simple, which causes the problem of shaking or offset between the bearings and the gears. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a gearbox bearing to solve the problems in the prior art that the connection strength between the gear and the bearing is to...
