Abstract

The invention relates to the technical field of gearboxes, in particular to a gear lubricating structure, a gear and a gearbox. The gear lubricating structure comprises an oil inlet hole, an oil inletpath and an oil outlet path, wherein the oil inlet hole is formed in the same side of a gear shaft hole, and the hole wall of the oil inlet hole is arranged to be in a streamline shape formed by splicing an arc section and a straight line section; the oil inlet path communicates with the arc section; and one end of the oil outlet path communicates with the oil inlet path, and the other end of theoil outlet path communicates with the gear tooth end. As shown in figure 1, due to the fact that the size of the oil inlet hole is large, the oil outlet amount on the gear is increased on the premisethat the amount of lubricating oil in the gearbox is not changed, moreover, when the gear rotates anticlockwise, the lubricating oil enters the oil inlet path after being accelerated by the straightline section and the arc section in sequence under the action of centrifugal force, by means of the design, the oil inlet speed can be increased, then the oil outlet speed is increased, the flowing speed of the lubricating oil is increased, the heat dissipation effect on the gears is improved, stable meshing between the gears is guaranteed, and the service life of the gear is prolonged.

Description

technical field [0001] The invention relates to the technical field of gearboxes, in particular to a gear lubricating structure, a gear and a gearbox. Background technique [0002] The transmission of the gear mainly depends on the relative occlusion of the tooth surface of the gear to carry out movement and transmission, so that the gear will produce some friction and wear during the movement process. If you want to ensure its normal movement, you need to add lubricating oil to the tooth surface for lubrication. [0003] However, the existing lubricating method has a poor lubricating effect due to the limited oil output, and because the lubricating oil flows slowly, the heat dissipation effect of the gear is poor, which directly shortens the service life of the gear. Contents of the invention [0004] The purpose of the present application is to provide a gear lubricating structure, a gear and a gearbox to solve the problem of poor gear lubricating and heat dissipation ef...
