FIELD: machine building.SUBSTANCE: invention refers to machine building, and namely to transmission devices converting the rotational movement into oscillation motion simultaneously in longitudinal and transverse directions in respect to two mutually perpendicular axes. The device comprises a casing (1), a driving shaft (2) with a hold-down nut (3) and a rotation-to-oscillation converting mechanism. The motion converting mechanism comprises a rolling bearing (4) installed on the driving shaft with bevelling. The inner race (5) of the rolling bearing (4) is mounted between two pressing bushes (6 and 7) with their ends being conjugated with the inner race of the rolling bearing, made with bevelling and fixed by the hold-down nut (3). Bevelling angles of the pressing bushes (6 and 7) are identical to the bevelling angle of the rolling bearing (4). The rolling bearing is installed (4) in a cage (10) on which working members affecting the external environment are mounted. The device comprises also a travelling arrester made as a spring (12) with one its end being fixed to the device casing (1) at the driving shaft (2) output and the other end - to the cage (10) housing.EFFECT: conversion of rotational movement into oscillation motion simultaneously by three mutually perpendicular axes.2 cl, 1 dwg |
