Abstract

PURPOSE: To improve work efficiency of a machine tool, etc. which is equipped with a screw type mechanism by providing a change gear mechanism which changes the number of rotation corresponding to the shifting movement of a rotating part member which is supported so that it is shifted by load.
CONSTITUTION: A torque limiter 22 is provided on a middle shaft 18 between a driving shaft 27a and a rotating member 1. A nonfeeding gear 22a of the torque limiter 22 can be engaged with a main gear 2 and it slips on a supporting member 22b when a torque over a prescribed value is applied on said member 22b. Therefore, when the nonfeeding gear 22a and the main gear 2 are engaged, an auxiliary gear 8 rotates in a different speed from that of the rotating member 1. Contrary to that, when the nonfeeding gear 22a and the main gear 2 are disengaged and the main gear 2 is engaged with the auxiliary gear 8 through clutches 2a, 8a, the auxiliary gear 8 and the rotating member 1 rotate in the same speed, so that the torque can be increased.
