SU474648A1 - Rolling Bearing Method - Google Patents

Description

The invention relates to a measurement technique, in particular, to the assembly of parts of rolling bearings before they are assembled.

Known methods for assembling rolling bearings are based on measuring the diameters of the raceways of the outer and inner rings of the bearing and determining, by their half-difference, the required group of rolling elements, which provides the required radial clearance in the sub-shaft.

However, to measure the raceways of the rings, model rings are required, the attestation error of which is then included in the measurement error, which does not provide high accuracy in the assembly of bearings in terms of the radial clearance.

The purpose of the invention is to improve the accuracy of the assembly of bearings.

For this, between the raceways of the outer and inner rings of the bearing, without prior measurement, the certified rolling bodies (at least four) are set at an equal distance around the circumference, the radial clearance is measured and a group of rolling bodies necessary for picking is determined according to the measurement result, ensuring the required bearing clearance.

The dryness of the method is illustrated in the drawing.

On the mandrel / set still

the inner ring 2 of the bearing, and its outer ring 3 is set relative to the inner ring so that at least four certified rolling bodies can be inserted into the crescent-shaped gap formed between them, after which the rolling bodies are evenly or manually distributed by other means rolling rings as shown in the drawing.

In the position shown on the rolls, the rolling bodies are measured in a known manner with the aid of the device 4, the radial clearance between the rolling bodies certified rolling tracks of the assembly rings. From the obtained result, the measurements determine the rolling elements necessary for picking up the ground, providing the required radial clearance in the bearing.

Subject invention

The method of picking rolling bearings, which consists in measuring the radial clearance between the raceways of the outer and inner rings of the bearing and determining the group of rolling elements necessary for picking, which provides the required clearance in

a bearing, characterized in that, in order to increase the accuracy of the assembly of bearings, at least four pieces are set at an equal distance around the circumference of the certified rolling bodies between the outer and inner bearing raceways and then the radial clearance is measured.
