Problems solved by technology
Bearings are generally composed of inner rings, outer rings, cages, rolling elements, and sealing rings. Due to their simple structure and easy use, bearings are widely used in the mechanical field. The higher the precision, the smaller the friction, and the longer the service life of the bearing, but there must be certain requirements for the gap between the inner ring, outer ring and rolling parts of the existing bearing, otherwise, it is difficult to install the rolling parts to the balls of the inner ring and outer ring In the orbit, this also brings a certain degree of difficulty to the processing and manufacturing

The invention provides an inner ring combined type high-precision bearing. The inner ring combined type high-precision bearing comprises an outer ring and an outer ring. Rolling elements are arranged between the outer ring and the inner ring and fixed though a retainer. The inner side of the outer ring and the outer side of the inner ring are provided with rolling grooves for containing the rolling elements. The inner ring comprises an inner ring body. The inner ring body is provided with a notch. A supplement block is arranged in the notch to form the complete inner ring. The supplement block and the inner ring body are connected and fixed through hexagon socket bolts. According to the inner ring combined type high-precision bearing, the notch is formed in the inner ring of the bearing first; after the rolling elements are mounted on a roller way between the grooves of the inner ring and the outer ring, and mounting is convenient; the gaps between the rolling elements and the grooves of the inner ring and the outer ring are controlled conveniently, and the machining precision is improved.
Description
technical field [0001] The invention relates to the technical field of bearing processing, in particular to an inner ring combined high-precision bearing. Background technique [0002] Bearings are components that fix and reduce the friction coefficient of loads in the process of mechanical transmission, and require relatively high precision in size and mechanical properties. Bearings are generally composed of inner rings, outer rings, cages, rolling elements, and sealing rings. Due to their simple structure and easy use, bearings are widely used in the mechanical field. The higher the precision, the smaller the friction, and the longer the service life of the bearing, but there must be certain requirements for the gap between the inner ring, outer ring and rolling parts of the existing bearing, otherwise, it is difficult to install the rolling parts to the balls of the inner ring and outer ring In the track, this also brings certain difficulties to processing and manufactu...
