Gear reducer, disc and corona cycloids for power steering system

摘要

The invention refers to a pair -reducing cyclidal gears (1) comprising an input rod (2),Mounted on a reducer housing so that it rotates around an axis referred to as the "main axis" (zz),An eccentric member (22) contained by the input rod (2) and rotated by the latter,At least one cyclidal (23) disc rotated on said eccentric member (22) and with a cyclidal gear (23t),At least one ring -gear (25) fitted with a receiving gear (25t) with which the cycloid gear (23t) of the cyclidal disc intertwines,And an exit rod (3),Separate from the input rod (2),Arranged to be rotated by the cycloid disc (23);Disc (23t) cyclidal gear (23t) and the corresponding ring gear (25) receiving gear (25t) being helicoidal.
