Tapered roller bearing ring height difference measurement device

Abstract

The invention relates to a tapered roller bearing ring height difference measurement device. The measurement device comprises a pressure board and a measurement gauge, wherein the pressure board comprises an outer pressure board and an inner ring pressure board, the outer pressure board comprises an annular outer ring pressure sleeve, one axial end of the outer ring pressure sleeve is a pressing end pressing against an outer bearing ring, the outer ring pressure sleeve is provided with a fixing cover board, the inner ring pressure board is matched in the outer ring pressure sleeve in a mode of doing axial guiding sliding along the outer ring pressure sleeve, one end of the inner ring pressure board consistent with the pressing end of the outer ring pressure sleeve in direction is a compaction end pressing against an inner bearing ring, the other axial end of the inner ring pressure board has a measurement reference surface, the measurement reference surface is fixedly mounted on the fixing cover board, and a gauge head of the measurement gauge stretches into the outer ring pressure sleeve and is in pressing matching with the measurement reference surface. The measurement device is advantaged in that operation is convenient, measurement is reliable, and the measurement device is applicable to measurement of batch production.

Description

technical field [0001] The invention relates to a measuring device, in particular to a measuring device for detecting the height difference between an end face of a bearing outer ring and a bearing inner ring of a tapered roller bearing. Background technique [0002] Tapered roller bearings are mainly used to bear combined radial and axial loads, mainly radial loads. Single row tapered roller bearings generally need to be used in pairs to balance the axial force. [0003] In some low-speed and vibration-bearing occasions, single row tapered roller bearings need to be installed without clearance or with pre-interference installation. The size of the clearance or pre-interference is adjusted by the thickness of the spacer. The purpose is to make the rollers and raceways of tapered roller bearings have good contact, distribute the load evenly, and prevent the rollers and raceways from being damaged by vibration and impact. . In this way, it is necessary to measure and contro...

Problems solved by technology

[0004] like figure 1 As shown, the conventional measurement of the distance h value between the wide end face of the outer ring of the tapered roller bearing and the narrow end face of the inner ring requires measuring the total height H, and then subtracting the height B of the inner ring and the height A of the pressure plate, the measurement efficiency is low, and the measurement link Many, large error, not suitable for mass production
