Starting device for rotating internal-combustion engine in motor vehicle, has rolling bodies exhibiting width between side surfaces, where width is reducible around specific range of percentage in relation to diameter of ball base

摘要

The device (1) has a sun wheel (13) with a sun wheel shaft (18) that is supported in a radial antifriction roller bearing (19) e.g. grooved ball bearing, with an outer ring (20), an inner ring (21) and rolling bodies (22) that are arranged between the rings. The rolling bodies are designed as ball rolls e.g. spherical washers, formed with two side surfaces that are flattened symmetrical from a ball base and arranged parallel to each other. The rolling bodies exhibit width between the side surfaces, where the width is reducible around 20-40 percent in relation to the diameter of the ball base.
