Abstract: The invention relates to an electromotive drive comprising an electric motor, having a driving pinion which meshes with a toothed wheel to form a first gear speed. A worm is connected to an output shaft of the toothed wheel in a fixed manner, enabling a worm wheel to be driven.

Abstract: A high torque resistant and strong screwless plastic gear box has a reduced thickness at its output shaft. The gear box and a reduction drive assembly therein may be used particularly, but not exclusively, in a slot machine with a spinning drum or hopper which holds coins or tokens to be released therefrom. The gear box includes a main body and a cover which is ultrasonically welded thereto. Locating posts, holding tubes, inner welding pads, outer surrounding tubes, and locating ribs are provided to weld the cover to the main body. Acoustical chambers are formed between outer walls and inner arcuate walls of the main body. The inner arcuate walls surround all of the shafts and gears inside the main body. This double-walled construction reduces noise and provides surprising mechanical strength. All of the gears are mounted on only three shafts secured between the main body and the cover. Four of the gears are stacked on a single central shaft and rotate in two pairs independently of each other.
