Measurement method and device for assembling height for single-row tapered roller bearing combination use

Abstract

The invention is called a method and a device for measuring the combined-use assembly height of single-row tapered roller bearing, which belongs to the technical field of assembling, inspecting and measuring tapered roller bearings. The invention mainly provides a method and a device for measuring the distance from the big end face of an outer sleeve to the small end face of an inner sleeve. The method is mainly characterized in that: 1. a hollow stepped shaft-shaped height standard component is manufactured according to design requirements; 2. a stepped three-point supporting measuring tableis adopted; 3. the standard component is placed in a step of the measuring table; a measuring head is in contact with the end face of an inner ring of a standard component step; a dial gauge is calibrated according to the actual height of the stepped-shaft-height standard component step; and 4. a to-be-measured bearing is placed on the measuring table, so that the measuring head is in contact with the small end face of the inner sleeve of the bearing; and whether the to-be-measured bearing is qualified or not can be determined according to corresponding values measured on the dial gauge. The device comprises a lever measuring claw, the supporting measuring table and the hollow stepped shaft-shaped height standard component. The invention is characterized in directness, reality and accurate measurement, and is mainly used for measuring the axial distance between the big end face of the outer sleeve and the small end face of the inner sleeve.

Description

Technical field [0001] The invention belongs to the technical field of assembly inspection and measurement of tapered roller bearings. Specifically, it relates to a method and device for measuring the axial distance between the large end surface of the outer sleeve of a tapered roller bearing and the small end surface of the inner sleeve, which is applied to the detection and configuration of the axial clearance before the combined use of the tapered roller bearing. Background technique [0002] The assembly height of tapered roller bearings is the distance T from the large end surface of the inner sleeve to the large end surface of the outer sleeve. See the labeling method figure 1 , Please refer to figure 2 . This marking and inspection measurement method is the most commonly used marking and inspection measurement method for the assembly height of tapered roller bearings. It can meet the measurement requirements of the assembly height of the tapered roller bearing in a single...

Problems solved by technology

This marking and inspection measurement method is the most commonly used marking and inspection measurement method for the assembly height of tapered roller bearings. It can meet the measurement requirements of the bearing assembly height under the single use of tapered roller bearings, but it cannot meet the single row tapered roller bearing combination. In the case of use, the bearing assembly has high measurement requirements, because the single row tapered roller bearings in combination use the tapered roller bearings The high assembly requirements are the distance t from the large end face of the outer sleeve to the small end face of the inner sleeve. For the marking method, see image 3 , so the original test measuring device cannot directly, truly and accurately measure the distance from the large end face of the outer sleeve to the small end face of the inner sleeve, so it is difficult to ensure the ideal axial clearance when the tapered roller bearing is used in combination
