Abstract
The utility model relates to a gear mechanism and particularly relates to a gear mechanism for a coaxial gear reducer. The gear mechanism comprises a box body, a shaft is arranged in the box body in a penetrating mode, a big gear is sleeved at the upper end of the shaft, a first stage pinion is sleeved at the lower end of the shaft, keys are arranged at two ends of the shaft, the upper end of the shaft and the box body are fixed through a tapered roller bearing, an upper oil baffle disc is arranged between the tapered roller bearing and the big gear, the lower end of the shaft and the box body are fixed through an angular contact ball bearing, and a lower oil baffle disc is arranged between the angular contact ball bearing and the first stage pinion. The gear mechanism for the coaxial gear reducer is simple in structure and good in usage effect.
Description
Technical field
The utility model is a kind of gear mechanism, particularly a kind of gear mechanism that is used for the coaxial-type gear reducer.
Background technique
