Compensation type friction-resistant gear

Abstract

The invention discloses a compensation type friction-resistant gear, and belongs to the field of gears. According to the compensation type friction-resistant gear, an oil-storing friction-reducing layer is arranged, every time the meshing of gear teeth can make contact with the oil-storing friction-reducing layer, so that lubricating oil in the oil-storing friction-reducing layer can be extruded and is adhered to the gear teeth, the friction between the two gear teeth is effectively reduced during the meshing of the gear teeth, and then the wearing time of the gear teeth is prolonged, namely,the service life of gears is effectively prolonged; and a flow compensation layer arranged in the gear teeth is in a balanced state in the gear teeth, and the gear teeth are extruded from inside to outside, when some parts of the gear teeth are worn out, the wall thicknesses of the parts are changed, so that the balance state is broken, the flow compensation layer is enabled to tend to be extrudedtowards the wear position, the strength of the parts are enabled to be compensated, the strength of the wear position is increased thus the time of the gear teeth being damaged is prolonged, and theservice life of the gears is further prolonged.

Description

technical field [0001] The invention relates to the field of gears, in particular to a compensating anti-friction gear. Background technique [0002] A gear is a mechanical element with teeth on the rim that can continuously mesh to transmit motion and power. It is a toothed mechanical part that can mesh with each other. The diameter of the large gear is twice the diameter of the small gear. The application of gears in transmission appeared very early. More than 300 BC, the ancient Greek philosopher Aristotle explained the problem of using bronze or cast iron gears to transmit rotary motion in "Mechanical Problems". At the end of the 19th century, the principle of generative gear cutting and the emergence of special machine tools and cutting tools using this principle made gear processing more complete. With the development of production, the stability of gear operation has been paid more attention. [0003] The gear is a mechanical element that relies on the continuous mes...

AI Technical Summary

Problems solved by technology

[0003] The gear is a mechanical element that relies on the continuous meshing of the teeth to transmit power. The traditional two gears mesh together, the wear is relatively large during transmission, and the noise generated at the same time is relatively large. The gear is easy to rust after a long time, which affects the relationship between the two gears. In order to solve this problem in the prior art, the first method is usually to manually lubricate the gear after the gear has been used for a period of time. The existing method is to periodically lubricate the outer ring of the mechanical transmission gear. Applying lubricating oil, but this method is time-consuming and laborious, the operation is inconvenient, and the work efficiency is low, which increases the labor intensity of the staff. The second method is to provide an oil chamber inside some gears, and the oil in the oil chamber during work From the oil outlet to the outer ring of the gear, lubricating the teeth of the outer ring of the gear can effectively reduce friction, but since the oil outlet is always open, the lubricating oil in the oil chamber will Running out of the oil outlet will accelerate the loss of lubricating oil and increase the cost of the enterprise
