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

The trap measuring method of the end-play of cageless four-row tapered roller bearing

Technical field

The present invention relates to a kind of trap measuring method of end-play of bearing, specifically is a kind of trap measuring method of cageless four-row tapered roller bearing.

Background technology

The trap measuring method of existing four-row tapered roller bearing is as far as traditional four-row tapered roller bearing that spacer ring is arranged; Usually adopt reconditioning internal space ring and external space ring width to adjust the end-play of bearing, tradition has the trap method parts of four-row tapered roller bearing of spacer ring many, installs complicated; Measuring and adopting calculating gauge block value is benchmark; Personal error is big, and calculation of complex is for the at present domestic measuring method that does not have maturation of cageless four-row tapered roller bearing trap.

Summary of the invention

The measuring method that the purpose of this invention is to provide a kind of cageless four-row tapered roller bearing trap is for the processing of bearing trap provides effective theoretical foundation.

The technical scheme that adopts is:

The trap measuring method of the end-play of cageless four-row tapered roller bearing comprises the steps:

At first establish outer ring AB and ED face size tolerance is a, outer ring BC and DC face size tolerance are made as b, and inner ring face size tolerance is made as c, and play is made as A ~ B;

The first step:

Measure the C face, supporting inner ring end face A, E planar survey.(see figure 2)

With the inner ring end face is the benchmark zero-bit, measure cycle surface and be lower than inner ring end face A/2 ~ B/2, promptly-A/2 ~-B/2.

If the value of measuring guaranteeing under the high situation of assembling greater than-A/2, grinding cycle surface C face to-A/2 ~-B/2;

If the value of measuring guaranteeing under the high situation of assembling less than-B/2, grinding inner ring end face C face to-A/2 ~-B/2;

Second step:

Measure the A face, supporting inner ring end face C planar survey.(see figure 3)

With the inner ring end face is the benchmark zero-bit, measure cycle surface and be lower than inner ring end face A/2-a-b ~ B/2-a-b, promptly-(A/2-a-b) ~-(B/2-a-b),

Because outer ring AB face size tolerance is a, outer ring BC face size tolerance is b, and play is a+b-((A/2-a-b) ~-(B/2-a-b))+(A/2 ~ B/2)=A ~ Bmm after the trap.

If the value of measuring is greater than-(A/2-a-b) grinding outer ring raceway, to-(A/2-a-b) ~-(B/2-a-b);

If the value of measuring is less than-(B/2-a-b) grinding outer ring AB end face B face, this moment, measured value was constant, but play changes (reducing).

The 3rd step:

Measure the E face, supporting inner ring end face C planar survey.(see figure 4)

With the inner ring end face is the benchmark zero-bit, measure cycle surface and be lower than inner ring end face A/2-a-b ~ B/2-a-b, promptly-(A/2-a-b) ~-(B/2-a-b);

Because outer ring ED face size tolerance is a, outer ring DC face size tolerance is b, and play is a+b-((A/2-a-b) ~-(B/2-a-b))+(A/2 ~ B/2)=A ~ Bmm after the trap.

If the value of measuring is less than-(B/2-a-b) grinding outer ring ED end face D face, this moment, measured value was constant, but play changes (reducing).

Advantage of the present invention:

This measuring method: can cancel inside and outside three spacer rings, reduce the bearing parts, be the benchmark zero-bit with the inner ring end face, directly measures the cycle surface drop, convenient measurement, and the trap straightforward is calculated simple.

Embodiment:

The first step: establish outer ring AB and ED face size tolerance is a, outer ring BC and DC face size tolerance are made as b, and inner ring face size tolerance is made as c, and play is made as A ~ B.

Second step:

At first support the measurement of inner ring end face C face, supporting inner ring end face A face and supporting inner ring end face E face;

The 3rd step:

Measure outer ring A face, supporting inner ring end face C face:

If the value of measuring is less than-(B/2-a-b) grinding outer ring AB end face B face, this moment, measured value was constant, but play diminishes.

The 4th step:

Measure outer ring E face, supporting inner ring end face C face:

With the inner ring end face is the benchmark zero-bit; Measure cycle surface and be lower than inner ring end face A/2-a-b ~ B/2-a-b; Promptly-(A/2-a-b) ~-(B/2-a-b); Because outer ring ED face size tolerance is a, outer ring DC face size tolerance is b, and play is a+b-((A/2-a-b) ~-(B/2-a-b))+(A/2 ~ B/2)=A ~ Bmm after the trap.

If the value of measuring is less than-(B/2-a-b) grinding outer ring ED end face D face, this moment, measured value was constant, but play diminishes.
