Abstract

PURPOSE: To make easier the assembling operation of a light-load device as well as raise its assembling accuracy by integrally combining a lower bearing case, a rotary ram to support the lower bearing case and also to generate a thrust force, and a stationary cylinder to cover the periphery of the rotary ram.
CONSTITUTION: A rotary ram 71 is integrally combined with a sleeve 72, the inner circumference of a lower bearing 103 is fitted on the periphery of a ram sleeve 72, a lower bearing case 74 fitted on the periphery of the lower bearing is integrally combined with a stationary cylinder 73 by a light-load base. Thus, a ram hole 78 into which a rotary shaft is inserted and the inside diameter of a ram sleeve 72 can be easily machined concentrically and also the bearing case 74 and the inside diameter of the stationary cylinder 73 can be machined concentrically. A light-load device 7 can be solely assembled and regulated on a surface plate, etc., before motor is built in, and therefore, the needs for making allowance for installing error at the time when motor is built in can be eliminated for setting up the fitting clearance of ram.
