Technical Field

The invention relates to the technical field of bearings, in particular to a CBN grinding wheel dressing spindle of a bearing grinding machine.

Background

The bearing is an important part in the present generation mechanical equipment, its main function is to support the mechanical rotating body, reduce the friction coefficient in its motion process and ensure its rotation precision, according to the difference of friction properties of moving elements, the bearing can be divided into two categories of rolling bearing and sliding bearing, in which the rolling bearing is standardized and serialized, but its radial size, vibration and noise are larger and its price is higher than that of sliding bearing, the rolling bearing is generally composed of four portions of outer ring, inner ring, rolling body and retainer, according to the shape of rolling body, the rolling bearing is divided into two categories of ball bearing and roller bearing, when other parts produce relative motion on the shaft, the rolling bearing is a part which is a kind of heavy component in the present generation mechanical equipment and is used for reducing the friction coefficient in the power transmission process and keeping the central position of the shaft fixed, in the mechanical product, the bearing belongs to a high-precision product, not only needs comprehensive support of various subject theories such as mathematics, physics and the like, but also needs various subjects such as material science, heat treatment technology, precision machining and measuring technology, numerical control technology, effective numerical method, powerful computer technology and the like to serve, so that the bearing is a product representing the national technological strength.

The grinding wheel is a consolidation grinding tool which is formed by consolidating common grinding materials into a certain shape (mostly circular, a through hole is arranged in the center) by a bonding agent and has certain strength, generally comprises the grinding materials, the bonding agent and the air hole, the same processing of the grinding wheel generally needs to use a CAB grinding wheel dressing main shaft to dress the grinding wheel, and the current CAB grinding wheel dressing main shaft has unreasonable internal design, low rotation precision and large vibration, so that the roughness of a ground product is large, and the service life of a bearing is influenced.

Disclosure of Invention

Technical problem to be solved

Aiming at the defects of the prior art, the invention provides a CBN grinding wheel dressing main shaft of a bearing grinding machine, which solves the problem that the service life of a bearing is influenced due to the fact that the roughness of a ground product is large because the internal design of the existing CAB grinding wheel dressing main shaft is unreasonable, the rotation precision is low and the vibration is large.
