Method for grinding double-row tapered roller bearing raceway

Abstract

The invention discloses a method for grinding a double-row tapered roller bearing raceway. The method includes the steps that a machine tool is adjusted to a set angle, the angle of a grinding wheel spindle is firstly adjusted, a grinding wheel is adjusted to the angle of the double-row pushing tapered roller bearing raceway so that the double-row pushing tapered roller bearing raceway is horizontally attached to the grinding wheel for grinding, after the grinding, the grinding wheel angle is the angle of one-sided raceway, then the machine tool head angle and the grinding wheel spindle angel are adjusted to form a right angle between the grinding wheel spindle and a workpiece shaft, the outer diameter of the grinding wheel is adjusted to be parallel to the raceway, the raceway machining is performed and finished according to the set accuracy, the grinding wheel spindle is moved to the centre of the raceway, the grinding wheel spindle and the raceway are adjusted to the angle between the tapered roller conical surface and a longitudinal parabolic curve to perform grinding, and the grinding is performed to achieve the set accuracy. The method for grinding the double-row tapered roller bearing raceway has the advantages that the implementation is convenient, the method is simple, the operation is easy, the work efficiency is increased by a few times, and the product quality can be guaranteed.

Description

technical field [0001] The invention relates to a processing method of a bearing, in particular to a method for grinding a raceway of a double-row tapered roller bearing. Background technique [0002] Bearings usually consist of an inner ring, an outer ring, multiple rollers and a cage. The multiple rollers are installed in the corresponding pockets on the cage seat and then placed in the raceway formed by the inner ring and the outer ring. The frame cover is fixed on the upper end surface of the cage seat. The modified contact line at the contact point between the roller and the raceway of the double-row tapered roller bearing can reduce stress concentration, and the tapered roller bearing can bear greater radial load and axial load, and the raceway with an inclination angle can make the cone Roller bearings bear combined radial and axial loads, which makes tapered roller bearings an ideal choice in many applications, and the most widely used tapered roller bearings are do...

Problems solved by technology

[0003] Double-row thrust tapered roller bearings and press-down bearings are different from other thrust tapered roller bearings. The raceways of these products are wider. The traditional processing method is to grind the grinding wheel and the workpiece at irregular angles. According to the traditional processing method , this angle is difficult to grasp, the quality cannot be guaranteed, and the production efficiency is low
