Problems solved by technology

[0004] The purpose of the present invention is to overcome the above-mentioned shortcomings such as the lack of lubricating oil in the teeth of the existing gears, which may easily cause wear in the meshing area, reduce the service life, and poor lubrication effect, and provide a new type of internal self-lubricating gear that releases itself during the gear transmission process. To the surface of the gear teeth, saving lubricating oil, effectively slowing down the wear of the gear teeth, reducing the cost of use and prolonging the service life

Abstract

The invention relates to a novel internal self-lubricating gear which comprises a plurality of gear teeth. Each gear tooth is internally provided with a cavity. The engagement area of each gear tooth is provided with a plurality of first holes. A body is provided with one or more second holes. The first holes and the second holes all communicate with the cavities. The second holes are provided with one-way valves. By adoption of the novel internal self-lubricating gear, the engagement areas of the gear tooth can be automatically and continuously lubricated, the lubricating effect is improved, the lubrication area is wide, abrasion to the gear teeth is reduced, the service life of the gear is prolonged, reliability and safety of gear working are improved, the safety problem that lubricating oil is inconvenient to add during work of the gear is solved, lubricating oil waste is reduced, lubricating oil leakage caused by an oil bath mode is avoided, cost is saved, the structure is simple, machining is convenient, and the gear is particularly suitable for a low-speed heavy-load large reducer.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission, in particular to a novel internal self-lubricating gear. Background technique [0002] Gears are the transmission medium between machines. The gear mechanism is used to transmit the motion and power between two shafts, which provides the possibility for the transmission of kinetic energy in different directions. Due to the high transmission efficiency of gears, accurate transmission ratio, long service life, safe and reliable work, Therefore, gear transmission equipment is widely used in all walks of life. Its types and sizes are various, and the application requirements that need to be met are also different. However, as one of the key components of various transmission equipment, gears have a certain performance. To a certain extent, it directly determines the service life of the entire equipment. [0003] During the use of the reducer, it mainly depends on the meshing between ...
