Detailed Description

The utility model provides a machine of shifting with sliding ring, includes the quick-witted box of shifting 1, servo motor B1, RD speed reducer B5, sliding ring B3, its characterized in that:

a mounting flange support 2 is fixedly arranged in a box body 1 of the positioner, a support cover plate 3 is arranged at one end of the flange support 2 to prevent dust from entering a mechanism, a motor connecting plate 7 is fixedly arranged on the flange support 2, and a shell of a servo motor B1 is fixedly arranged on the motor connecting plate 7. A first bearing B2 is installed in the through hole of the motor connecting plate 7, and a power output shaft of the servo motor B1 penetrates through an inner ring of the first bearing B2 and is fixedly connected with the first bearing B2. The servo motor B1 is arranged on the motor connecting plate 7 through a first bearing B2, the positioning strength is improved, and the pinion 4 is fixedly sleeved on a power shaft of the servo motor B1.
