A self-lubricating gear

Abstract

The invention discloses a self-lubricating gear and belongs to the field of transmission devices. The self-lubricating gear comprises a gear body, a gear shaft and a plurality of gear teeth. The gear body is cylindrical. The gear teeth are arranged on the circumferential surface of the gear body in the circumferential direction of the gear body. The gear shaft is coaxially connected with the gear body. The self-lubricating gear further comprises baffles and switch assemblies, and the switch assemblies are in one-to-one correspondence with the gear teeth. The gear shaft is internally provided with a shaft hole communicating with the outside. The end face of the gear body is provided with end face grooves which are in one-to-one correspondence with the gear teeth. The gear teeth are provided with tooth grooves extending to the tooth crest curved surfaces or the tooth surfaces of the gear teeth. The tooth grooves are provided with first ports which are formed in the tooth crest curved surfaces or the tooth surfaces of the gear teeth and communicate with the outside. The end face grooves communicate with the shaft hole and the tooth grooves of the corresponding gear teeth. The end face grooves and the tooth grooves are covered with the baffles. The switch assemblies are arranged in the tooth grooves and communicate the end face grooves communicating with the tooth grooves with the first ports when the corresponding gear teeth are engaged with a toothed mechanical part. The self-lubricating gear is simple in process and convenient to realize.

Description

technical field [0001] The invention relates to the field of transmission devices, in particular to a self-lubricating gear. Background technique [0002] A gear is a wheel-shaped mechanical part with gear teeth on the circumferential surface of the wheel body, and the transmission is realized by meshing the gear teeth with other tooth-shaped mechanical parts. If there is not enough lubrication on the teeth of the gear, the gear teeth will be greatly damaged during the rotation of the gear, which will reduce the service life of the gear, so the transmission of the gear cannot be separated from lubrication. [0003] At present, the way of gear lubrication is to open an oil storage chamber inside the gear and oil outlet through holes and slide rod through holes corresponding to the gear teeth on the gear one by one. The oil storage chamber is arranged in the center of the gear, and multiple oil outlet holes Extending from the oil storage cavity radially along the gear to the ...
