Internal gear lifting and rotating mechanism applied to grinding equipment
2013
The invention discloses an internal gear lifting and rotating mechanism applied to grinding equipment. The internal gear lifting and rotating mechanism is characterized in that the internal gear lifting and rotating mechanism comprises an internal gear component, an internal gear lifting device and an internal gear rotating device; the internal gear component comprises a rotating bearing, an external gear mounted on the rotating bearing and an internal gear mounted in the external gear; the internal gear lifting device is fixedly connected with the rotating bearing in the internal gear component to drive the internal gear component to ascend and descend; the internal gear rotating device is meshed with the external gear in the internal gear component to drive the external gear to rotate. By the internal gear lifting and rotating mechanism, lifting and rotating of the internal gear component and separating of a central transmission component can be realized, application of a hollow shaft can be reduced, rigidity and transmission accuracy of a rotating shaft of the central transmission component of a machine tool can be improved, precision and surface quality of processed workpieces can be improved, equipment production cost can be reduced, and equipment stability can be improved.
