Problems solved by technology

[0002] The existing four-row tapered roller bearing combined measurement method is for the traditional four-row tapered roller bearing with a spacer. Usually, the axial clearance of the bearing is adjusted by grinding the width of the inner and outer spacers. Traditionally, there are The fitting method of four-row tapered roller bearings with spacers has many parts and complex installation, and the measurement uses the calculated gauge block value as the reference, which has large human errors and complicated calculations. For the four-row tapered roller bearings without spacers, the fitting method is currently There is no mature measurement method in China

Embodiment Construction

[0031] A combined measurement method for the axial clearance of four-row tapered roller bearings without a spacer, including the following steps:

[0032] Step 1: Set the dimensional tolerance of the outer ring AB and ED end faces as a, the outer ring BC and DC end face dimensional tolerance as b, the inner ring end face dimensional tolerance as c, and the clearance as A ~ B.

[0033] Step two:

[0034] First, measure the C surface of the inner ring, the A surface of the inner ring and the E surface of the inner ring;

[0035] Taking the end face of the inner ring as the reference zero position, measure that the end face of the outer ring is lower than the end face of the inner ring A / 2 ~ B / 2, namely -A / 2 ~ -B / 2.

[0036] If the measured value is greater than -A / 2, under the condition of ensuring the assembly height, grind the end face C of the outer ring to -A / 2 ~ -B / 2;

[0037] If the measured value is less than -B / 2, grind the end surface C of the inner ring to -A / 2 ~ -B / ...

Abstract

The invention discloses a method for fitting and measuring the axial clearance of a spacer-free four-column tapered roller bearing. The method comprises the following steps of: 1, measuring a bearing inner ring end surface C, a bearing inner ring end surface A and a bearing inner ring end surface E; 2, measuring an outer ring surface A and the bearing inner ring end surface C; and 3, measuring an outer ring surface E and the bearing inner ring end surface C. The method has the advantages that: three internal and external spacers can be removed, and bearing parts can be reduced; and the inner ring end surface is used as a reference zero position to directly measure the level difference of an outer ring end surface, so that the axial clearance is convenient to measure, can be clearly and easily fitted and is easy to calculate.

Description

technical field [0001] The invention relates to a method for measuring the axial clearance of a bearing, in particular to a method for measuring the combination of a four-row tapered roller bearing without a spacer. Background technique [0002] The existing four-row tapered roller bearing combined measurement method is for the traditional four-row tapered roller bearing with a spacer. Usually, the axial clearance of the bearing is adjusted by grinding the width of the inner and outer spacers. Traditionally, there are The fitting method of four-row tapered roller bearings with spacers has many parts and complicated installation, and the measurement uses the calculated gauge block value as a reference, which has large human errors and complicated calculations. For four-row tapered roller bearings without spacers, the fitting method is currently There is no mature measurement method in China.
