ABSTRACT:
An elevator hoist apparatus con, rising a base, a speed reduction mechanism mounted on the base and including an input shaft to which driving power source is to be connected and an output shaft to which a sheave is connected, and a cover mounted to the base and covering the speed reduction gear. The speed reduction mechanism my comprise a bearing pedestal mounted to the base and a plurality of parallel axis gears supported by the bearing pedestal. A positioning means is disposed between the base and the speed reduction mechanism for positioning the bearing pedestal of the speed reduction mechanism relative to the base. At least one of the bearing pedestals of the speed reduction mechanism may be at least partially supported by other of the bearing pedestals. The speed reduction gear mechanism includes an intermediate gear and wherein the bearing pedestal supporting the intermediate gear is in engagement with and supported solely by the bearing pedestal supporting the input shaft and the bearing pedestal supporting the output shaft. A method for manufacturing an elevator hoist apparatus comprises the steps of preparing a base, mounting to the base a speed reduction mechanism including an input shaft to be connected to a driving power source and an output shaft to be connected to a rope sheave, and mounting a cover for covering the speed reduction mechanism to the base.
