A Calculation Method for Back-to-Back Tapered Roller Bearing Arrangement

Abstract

The invention discloses a calculation method for back-to-back tapered roller bearing configurations. According to the calculation method, the width of a bearing outer ring distance ring of a bearing seat (5) is fixed, pre-tightening of a bearing is determined according to the width of an inner distance ring (4). A metering tool and a subtraction calculation method are adopted, so that the inaccuracy problem of a plurality of measuring points of a plurality of measuring units is improved; the influence of the interference amount of a shaft sleeve and the bearing and the interference amount of the shaft sleeve and a shaft on bearing pre-tightening is calculated, so that the problem of accurate calculating of back-to-back tapered roller bearing configuration pre-tightening is solved; and the adopted calculation method is simple, scientific and effective, and batch production of the back-to-back tapered roller bearing configurations is achieved.

Description

technical field [0001] The invention belongs to the technical field of tapered roller bearings, and relates to a back-to-back tapered roller bearing configuration calculation method. Background technique [0002] At present, the back-to-back tapered roller bearing preload configuration method generally uses separate measurement of the outer ring spacer and inner ring spacer, and the width of the inner ring spacer or outer ring spacer is removed according to the preload to achieve the effect of preloading the bearing. Ordinary methods generally do not consider the radial interference fit relationship between the bearing and the shaft, the radial interference fit relationship between the bearing and the bushing, the width of different bearings, and the preload of back-to-back tapered roller bearings. These will have an impact on the bearing capacity and life of the bearing. Ordinary methods are difficult to meet the requirements of mass production, and the width of the spacer...

AI Technical Summary

Problems solved by technology

Ordinary methods generally do not consider the radial interference fit relationship between the bearing and the shaft, the radial interference fit relationship between the bearing and the bushing, the width of different bearings, and the preload of back-to-back tapered roller bearings. The impact of these will have an impact on the load capacity and life of the bearing

Ordinary methods are difficult to meet the requirements of mass production. It is necessary to measure the width of the spacer ring at different positions many times. The measurement is difficult, cumbersome and inaccurate
