Problems solved by technology

[0003] Nowadays, gears are used in many machines or tools. Most of the gears are metal products. They may rust or wear out after long-term use, resulting in inflexible rotation of the gears, affecting mechanical work, and greatly reducing the efficiency of mechanical work. The gears are tightly connected, and the lubricating oil cannot enter the inside of the gears well, so the gears cannot be lubricated well.

Abstract

The invention relates to a low-friction lubricating gear. The low-friction lubricating gear comprises a gear column and a gear body connected with the gear column; the gear body comprises a gear disc, a shaft hole and outer teeth; the shaft hole is located in the middle of the gear disc; the outer teeth are located on the periphery of the gear disc; an oil storage cavity is formed in the gear disc; one end of the oil storage cavity communicates with an oil injection hole in the gear column through an oil passage I; the other end of the oil storage cavity communicates with an oil outlet in a tooth groove of the outer tooth through an oil passage II; and a temperature variable-diameter check valve is arranged in the oil passage II. According to the low-friction lubricating gear, through the oil storage cavity in the gear disc and the temperature variable-diameter check valve in the oil passage, when the temperature of a gear is too high, oil in the oil storage cavity enters the oil outlet in the tooth groove of the outer tooth through the check valve, so that the purpose of gear lubrication is achieved; and meanwhile, through copper plating treatment on the surface of the gear body, the roughness of the tooth surface is improved, and the friction force during gear operation is reduced.

Description

technical field [0001] The invention relates to the technical field of mechanical transmission components, in particular to a low-friction lubricating gear. Background technique [0002] The gear is mainly through transmission with other toothed mechanical parts to realize functions such as changing the speed and torque, changing the direction of motion, and changing the form of motion. Due to the advantages of high transmission efficiency, accurate transmission ratio, and large power range, gear mechanisms are widely used in industrial products. The teeth of the gear interlocking with each other will drive the other gear to rotate to transmit power. [0003] Nowadays, gears are used in many machines or tools. Most of the gears are metal products. They may rust or wear out after long-term use, resulting in inflexible rotation of the gears, affecting mechanical work, and greatly reducing the efficiency of mechanical work. The gears are tightly connected, and the lubricating...
