Width-limited matching method for bearing width of tapered roller bearing

Abstract

The invention discloses a width-limited matching method for the actual bearing width of a tapered roller bearing. The width-limited matching method includes step 1 manufacturing standard inner assemblies and inner assembly inner circle diameter measuring tools; step 2 measuring inner circle diameters of the inner assemblies and dividing into groups; step 3 measuring the diameters of outer rings and dividing into groups; step 4 manufacturing bearing width measuring tools of bearing; step 5 preparing a bearing width matching table with respect to relation between the raceway diameter of the outer ring and the inner circle diameter of the inner assembly through a two-dimensional table; step 6 assembling inner assemblies in the same group and then the inner assemblies in all groups with the outer rings to form bearings in sequence, measuring the bearing width of each bearing, and at the meantime recording measured values in crossing table cells of row and columns of the matching table; and step 7 matching by group and assembling the outer rings and the inner assemblies of bearing according to deviation of specifications of bearing width of bearing and the recorded values in the bearing width matching table. According to the width-limited matching method, matching accuracy is increased, and repeated assembling and repeated measurements of bearing width are avoided.

Description

technical field [0001] The invention relates to a height-limiting matching method for the assembly height of a tapered roller bearing. Background technique [0002] With the application of bearings becoming more and more popular, the demand for bearings in all walks of life has greatly increased, the production scale of bearings has expanded rapidly, the output has increased rapidly, and the requirements for the accuracy of bearings have become more and more stringent. Require. There are many factors that affect the assembly height of the bearing, including the raceway size of the inner ring, the rib size, the diameter of the roller, and the diameter of the raceway of the outer ring. To control each influencing factor, the workload is undoubtedly huge, and excessive production costs will hinder the development of the enterprise, or even crush the enterprise. The deviation of the assembly height of conventional bearings is generally controlled within 0.20mm, while for heigh...
