There is 3rd bearing, baffle ring is provided on front side of the 3rd bearing, periphery and the housing bolt of the baffle ring, inner circumferential is with passing
The step surface passed on axis offsets.
The technical measures of optimization further include：
Fourth bearing and 5th bearing are provided between the housing and the input shaft.
The extending radially downward formation fixed plate in front end of the housing offers mounting hole in the fixed plate.
The sun gear and planetary gear is the helical gear being adapted.
The lower end of the housing is fixed with connecting flange.
The right angle reductor of the utility model by setting the baffle ring with housing bolt, can be realized to transmitting axle position
The fine tuning put so as to fulfill the adjustment to bevel gear meshing state, enables bevel gear meshing state to reach optimum state, and then
Improve transmission accuracy；In addition, be used to support output shaft rotation clutch shaft bearing and second bearing be respectively arranged at the two of sun gear
Side can widen the spacing between clutch shaft bearing and second bearing as much as possible, so as to which the support for enabling input shaft is stablized, keep away
Is there is beat by its rear end during radial load in the front end for exempting from output shaft.Generated vibration when being conducive to reduce speed reducer operation,
Noise is reduced, improves its service life.
