Abstract
The utility model discloses a locating device for the installation of a steering pipe column bearing. The locating device which is arranged on a steering driving shaft and installed inside a steering pipe column comprises a bearing, a non-metallic sheath, a precision locating ring and a shaft sleeve, wherein the surface of the non-metallic sheath is provided with grooves in the circumferential direction, and the non-metallic sheath is fixed on the bearing; the outer surface of the precision locating ring is provided with a plurality of bulges which are arranged in the grooves of the non-metallic sheath, and the external diameter of the precision locating ring is greater than that of the non-metallic sheath; the bearing is fixed on the shaft sleeve which is fixedly arranged on the steering driving shaft. The device can widen a traditional press fitting tolerance and decrease assembly force so as to adjust the resonant frequency of the whole device; the utility model also allows the shaft to tilt slightly and not align to the center so as to lower noise and reduce circumferential stress between a bearing seat and the bearing, and meantime, the utility model has the advantages of convenient assembly and disassembly and favorable heat radiation performance.
