Abstract

The invention discloses a gear shaft with a dustproof cover, which comprises a gear shaft body, one side of the gear shaft body is provided with a gear shaft rear end shaft body, and the other side of the gear shaft body is provided with a bearing sleeve, The side of the rear end shaft body of the gear shaft close to the bearing sleeve is provided with gear teeth, and the side of the gear teeth away from the rear end shaft body of the gear shaft is provided with the middle end shaft body of the gear shaft, and the middle end shaft of the gear shaft A pinion spline is embedded in the center of the pinion body, a cross-shaped oil groove is embedded in the surface of the pinion shaft body, and a pinion front end shaft body is set on the side of the pinion shaft body away from the pinion shaft spline. The present invention is different from the pinion on the market where the ordinary oil groove is embedded on the shaft surface, but a cross-shaped oil groove is embedded on the surface of the gear shaft shaft. When oil is injected through the cross-shaped oil groove, the lubricating oil can flow along the Add lubricating oil to the gear shaft to the maximum to lubricate, cool down, reduce gear wear and prolong the life of the gear shaft.

Description

technical field [0001] The invention belongs to the related technical field of gear shafts, and in particular relates to a gear shaft with a dustproof cover. Background technique [0002] A pinion is a mechanical part that supports and rotates with a rotating part to transmit motion, torque or bending moment. Generally, it is in the shape of a metal round rod, and each segment can have different diameters. The parts that make rotary motion in the machine are mounted on the shaft. According to the shape of the shaft, the shaft can be divided into two types: crankshaft and straight shaft. According to the bearing condition of the shaft, it can be divided into: the rotating shaft, which bears both bending moment and torque during work, is the most common shaft in machinery; the mandrel, which is used to support the rotating parts, only bears bending moment and does not transmit torque. The shaft rotates, and some spindles do not rotate; the transmission shaft is mainly used ...
