Abstract

The invention discloses a clearance adjusting method for a super-huge type square-head rivet single-row cylindrical roller bearing. Clearance adjustment is conducted on six supporting blocks as one group. The end faces of the two sides of inner rings, the end faces of the two sides of outer rings and the end faces of the two sides of holders are marked with A and B respectively. Before measurement, positioning end faces of the parts, located on the lower portions, of the inner rings and the outer rings should be located in the horizontal positions. When a traditional method is used for measurement, the bearing is horizontally placed, under the action of gravity, the holders can be pressed on the end faces of rollers, rotation is not flexible, and consequently the accuracy of measurement of a clearance is affected. The first supporting blocks are arranged on the end faces of the inner rings and the end faces of the outer rings respectively, and the second supporting blocks are placed on the end faces of holder seats, and therefore the influences of the holders on the rollers are eliminated, the bearing can run normally, and the measured clearance is more accurate. According to the clearance adjusting method, the influences of the holders on the bearing clearance are eliminated, operation is simple and convenient, and accuracy is high.

Description

Super-huge square toes riveting single row roller bearing play adjusting method

Technical field

The present invention relates to bearing mnanufacture technical field, what be specifically related to is a kind of super-huge square toes riveting single row roller bearing play adjusting method.

Background technique

Traditional super-huge single row roller bearing clearance measurement method needs a measuring table, but the measuring table needed for extra large size bearing is larger, manufacture cost is higher, when user checks bearing clearance before installation, cannot detect accurately.

Summary of the invention

The present invention improves the accuracy measuring operation, provide a kind of easy without platform super-huge square toes riveting single row roller bearing play adjusting method, when the method is measured, inside and outside circle, retainer and roller are paved, eliminate the impact that retainer is measured play, easy and simple to handle, accuracy is high.

The technological scheme adopted is:

Super-huge square toes riveting single row roller bearing play adjusting method, comprises the following steps:

Preparation before step one adjusts

(1) bearing completed products part is through cleaning up after the assay was approved;

(2) during play adjustment, place the first support block in inner ring, outer ring respectively and place the second support block by maintenance stand, retainer lid by the retainer of square toes riveting, place respectively totally six pieces be that the support block of a group carries out, the height phase mutual deviation of same group of support block should be less than 50% of measured bearing inner ring both ends of the surface parallel error;

(3) on inner ring, outer ring, retainer both sides end face, A and B is marked respectively, the letter set by marking with electroprobe, and with tense marker upper bearing (metal) sequence number;

Step 2 adjustment requirement

(1) inner ring of bottom should be made to be assembled in before measuring, location, outer ring end face is horizontal;

(2) each row roller and lasso should be rotated respectively, to ensure that each part of bearing is all in normal position before measuring.

The first support block height in above-mentioned step one is set as 20mm, and the second support block height dimension is set to h, adopts each part height size of product specification to calculate, is calculated as follows:

This invention removes the impact that retainer adjusts bearing clearance, easy and simple to handle, accuracy is high.

Accompanying drawing explanation

Fig. 1 is alphabetic flag and the play adjustment schematic diagram of step one of the present invention.

Preparation before step one adjusts

(2) during play adjustment, place the first support block 6 respectively in inner ring 2, outer ring 1 and place the second support block 7 by maintenance stand 4, retainer lid 5 by the retainer of square toes riveting, place respectively totally six pieces be that the support block of a group carries out, the height phase mutual deviation of same group of support block should be less than 50% of measured bearing inner ring both ends of the surface parallel error;

Step 2 adjustment requirement

(1) inner ring 2, the outer ring 1 that should make to be assembled in bottom before measuring are located end face and are horizontal;

(2) each row roller 3 and lasso should be rotated respectively, to ensure that each part of bearing is all in normal position before measuring.

The first support block 6 in described step one is highly set as 20mm, and the second support block 7 height dimension is set to h, adopts each part height size of product specification to calculate, is calculated as follows:

When using conventional methods measurement, by bearing horizontal positioned, under gravity, retainer can be pressed on roller end face, rotates dumb, will affect the Measurement accuracy of play; The first support block 6 is placed on inner ring 2 and outer ring 1 end face by the present invention respectively, the second support block 7 is placed on the end face (see figure 1) keeping stand 4, thus eliminating the need the impact of retainer on roller 3, whole bearing just can run well, and the play therefore measured is just more accurate.

Claims

1. super-huge square toes riveting single row roller bearing play adjusting method, is characterized in that comprising the following steps:
