摘要： This torque limiter is configured from a ring body and a spring-form part provided in the ring body. The ring body comprises a band-form metal plate and is bent approximately into a C-shape along the circumferential direction of a motor shaft and a lock holder. The spring-form part is formed so as to be capable of radial elastic deformation. The spring-form part is configured from main protrusions arranged in a compressed state between the motor shaft and the lock holder, and from sub-protrusions arranged in a non-compressed state. Further, grease is stored in a part or all of the concavities formed by the main protrusions and the sub-protrusions.

摘要： In a multiple spindle processing unit which can change processing locations of a work in accordance with a modification made to the work, the present invention is intended to facilitate changes of design corresponding to the modification made to the work and reduce the number of parts to be replaced. In a frame member which is guided and supported so as to be moved towards and away from a work, insertion holes are formed at a plurality of locations corresponding to processing locations of the work. In each of a plurality of tool main spindle assemblies, a main spindle having a front end portion where a chuck for mounting a tool is provided is coaxially journaled in a housing in the shape of a circular cylinder or a polygonal cylinder and is rotationally driven by a built-in motor. Each of the tool main spindle assemblies is mounted to the frame member with the housing inserted through the insertion hole. The tool main spindle assembly may be mounted to the frame member through a holding plate which is divided into a plurality of portions for securely sandwiching the housing or through a flange which is integrated with the housing and which protrudes radially.

摘要： A fitting recess portion that connects fitting holes to each other is formed in a peripheral face of a ball screw nut. A circulation member includes a pair of fitted portions that are fitted in the fitting holes, and a connecting portion that provides communication between the fitted portions. A communication groove that has an opening on the fitted end side of the connecting portion and that extends in the axial direction is formed in the connecting portion. When the connecting portion is fitted in the fitting recess portion and the opening of the communication groove formed in the connecting portion is blocked by a bottom portion of the fitting recess portion, a second path that forms a return path together with first paths formed in the fitted portions is formed.

摘要： In a ball screw mechanism, a retainer is provided between an outer circumference of a ball screw shaft and an inner circumference of a ball nut and has a plurality of retainer grooves arranged in the circumferential direction for retaining a plurality of rolling balls. Each retainer groove of the retainer takes a form that allows the rolling balls therein to move radially outward but restrains the rolling balls therein from moving radially inward. Therefore, in the ball screw mechanism and an electric power steering device incorporating the same, the movement of the retainer in radial directions can be restricted by the plurality of rolling balls which are rolled along ball rolling grooves spirally formed respectively on the outer circumference of the ball screw shaft and the inner circumference of the ball nut.
