Abstract
The utility model provides a transmission device of a novel circuit breaker, which is used for controlling the on-off of the circuit breaker and comprises a transmission shaft and a transmission shaft support. A lubricating shaft sleeve is arranged at the connecting part between the transmission shaft and the transmission shaft support; and a lubricating oil groove is arranged on the inner wall of the lubricating shaft sleeve. Lubricating oil can be filled in the lubricating shaft sleeve of the transmission device, which not only effectively increases the transmission efficiency but also prolongs the service life of the transmission shaft and the transmission shaft sleeve; moreover, the transmission shaft and the lubricating shaft sleeve are made of different materials, so that friction factors of the transmission shaft and the transmission shaft sleeve are effectively decreased and the transmission efficiency is improved.
Description
Technical field
The utility model relates to a kind of jockey, relates in particular to a kind of novel breaker transmission device.
Background technology
Transmission device is the middle device that is used for transferring power between a plurality of power set, as in circuit breaker, breaker closing, cut-off by breaker operation mechanism and drive, overlap the transmission device of forming by connecting rod and power transmission shaft etc. by one between breaker operation mechanism and circuit breaker deciliter contact.In the transmission process, have wearing and tearing in the junction of power transmission shaft and support, this wearing and tearing will cause shortening of the connected parts of power transmission shaft useful life, and this wearing and tearing also can cause the stability in use and the service behaviour of power set.Many power set are by transforming for power transmission shaft, thereby increase its useful life and job stability.
China's notification number is the patent of CN201262311Y: the traveling wheel lubricating arrangement, on power transmission shaft, offer oil filler point, make when power transmission shaft is worked, can coat lubricating oil at itself and other connecting portion, thus the lubrication of playing, the coefficient of friction of less power transmission shaft and miscellaneous part, increase stability of transmission, with the useful life of power transmission shaft, but operation is loaded down with trivial details during the making of this power transmission shaft, has increased cost of manufacture.
