Problems solved by technology

However, during the processing, due to the vibration of the main shaft, the gap between the outer diameter of the centering copper sleeve of the fixed centering device and the inner diameter of the processed product is unstable, and there is a certain eccentricity between the two, and the device does not have The automatic centering function causes the processed product to rub against the centering copper sleeve during high-speed rotation and wear, which increases the reject rate of the processed product, and the appearance quality of the inner ring of the bearing is poor, resulting in waste

Abstract

The invention relates to a bearing centering device, which comprises a centering shaft. The bearing centering device is characterized by also comprising a centering sleeve; the centering shaft comprises a first shaft shoulder; a bearing and a spring retainer ring are arranged in the centering sleeve; the spring retainer ring is clamped in a groove of the centering sleeve to inhibit axial movement of a bearing; the centering sleeve is arranged on the first shaft shoulder of the centering shaft through the bearing; and the centering sleeve is in interference fit with the bearing, and the inside diameter of the centering sleeve is greater than the outside diameter of the bearing. Through the bearing centering device of the scheme, the geometric tolerance of the bearing such as the inside diameter size precision, the roundness, the cylindricity and the like is improved, the rejection rate of a product is reduced, the appearance quality of the product is improved, and the cost is reduced; and the bearing centering device has a good using effect.

Description

technical field [0001] The invention relates to a centering device, in particular to a bearing centering device used in the groove processing of the inner ring of a bearing, and belongs to the technical field of mechanical parts. Background technique [0002] In the ultra-finishing of the groove of the inner ring of the bearing, oil is supplied by the hydraulic system, so that an oil film is formed between the fixed centering device and the inner diameter of the inner ring of the bearing, and the inner ring of the bearing is driven by the main shaft to rotate at a high speed. Under the oscillating grinding of the stone, the purpose of ultra-finishing the groove of the inner ring of the bearing is achieved. However, during the processing, due to the vibration of the main shaft, the gap between the outer diameter of the centering copper sleeve of the fixed centering device and the inner diameter of the processed product is unstable, and there is a certain eccentricity between ...
