Abstract

A motor driven cylindrical cam, rotating eccentrically to its geometric axis, enclosing a right angle with rotation axis of oscillation lever, engages the oscillation lever, which contains a bearing bore determining its rotation axis. The bore has slide faces enabling retention of two diametral bearing bolts. The slide faces of each bolt consists of specified cylindrical section, and the axial spacing of the bolts, i.e. between non-cylindrical section of bolt, complementary slide faces of bearing bore, and non-cylindrical of bolt slide faces are also specified.
