Abstract
A mechanical oscillator including a shaft having an endless groove in its periphery, a nut body carried by and slidable along the shaft at the location of the endless groove, and a roller pin carried by the nut body, having a nose portion extending into and engaging a wall of the endless groove and having a tail portion disposed deeply in the nut body. A plurality of anti-friction bearings is carried by the nut body, the bearings carrying the roller pin. The anti-friction bearings include both a ball bearing and a needle bearing, the ball bearing being disposed adjacent the nose portion of the roller pin, and the needle bearing being located adjacent the ball bearing and engaged with a tail portion of the roller pin. Multiple roller pins can be used, carried on two carrier strips respectively, which are axially displaced and disposed at opposite sides of the nut body. The carrier strips and associated roller pins can be removed as units, thereby simplifying replacement as required by damage or wear.
