Abstract
The invention relates to a no-platform clearance adjustment method for super huge double-row tapered roller bearings. Clearance adjustment is carried out on supporting blocks, and every six supporting blocks form one group. Firstly, AB and AC are respectively marked on the two side end surfaces of two outer rings, and A'C' is marked on the two side end surfaces of an inner ring. The axial clearance of the bearing is adjusted by adopting a method for preparing an outer ring spacer, and namely the determination of the width B1B1 of the outer ring spacer. Before measurement, the axial directions a and b from the end surfaces of the inner ring to the end surfaces of the outer rings are respectively measured at the positions I and II of the bearing, and the size BB is decided by the formula BB=A'C'-AB-BC-a-b; if the axial clearance is set as Ga, the B1B1 is decided by the formula B1B1=BB+Ga. The no-platform clearance adjustment method gets rid of the limitation that measurement cannot be carried out if no platform exists on site. The method has the advantages of being easy to operate and high in accuracy.
Description
Technical field
The present invention relates to bearing mnanufacture technical field, what be specifically related to is a kind of two single raceway outer rings, a two raceway inner ring, an outer ring spacer, inner ring assembling height in outer ring assembling high without platform super-huge double-row conical bearing play adjusting method.
Background technique
Traditional double-row conical bearing method of measurement needs a measuring table, but the measuring table needed for extra large size bearing is larger, manufacture cost is higher, when user produces query to bearing clearance, when needing staff to carry out the check of play to scene, general scene does not all have platform, therefore just in-site measurement cannot be carried out, rely on the method for measurement Applicable scope of large measuring table little, measure and have certain narrow limitation, the simultaneously manufacture of large platform and calibrating also have certain difficulty.
Summary of the invention
The present invention seeks to as improving the flexibility of measuring operation, provide without platform super-huge double-row conical bearing play adjusting method, do not need usage platform when the method is measured, only need place 6 cushion blocks at inner ring end face can measure, easy and simple to handle, accuracy is high.
The technological scheme adopted is:
Without platform super-huge double-row conical bearing play adjusting method, comprise the following steps:
Preparation before step one adjusts
A, bearing completed products part are through cleaning up after the assay was approved;
The adjustment of b, play is carried out on the support block that 6 pieces are a group, and 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;
C, on the end face of both sides, two outer rings, mark AB and BC respectively, inner ring both sides end face subscript note A ' C ', the letter set by marking with electroprobe, and with tense marker upper bearing (metal) sequence number;
Step 2 adjustment requirement
The inner ring location end face being assembled in bottom should be made before a, measurement to be horizontal;
Add load block at cycle surface when b, measurement, its load value should ensure rolling element and raceway even contact;
Each row roller and lasso should be rotated respectively, to ensure that each part of bearing is all in normal position before c, measurement;
Step 3 bearing clearance adjusts
The adjustment of bearing axial play adopts the method for preparation outer ring spacer to adjust, namely the method for described preparation outer ring spacer is the determination of external spacerband width size B1B1, inner ring end face is measured respectively to cycle surface axial distance a and b in the position I of bearing and position II, size before measuring.
BB is determined by (1) formula:
（1）
If axial internal clearance is set to Ga, then B1B1 calculates by (2) formula:
Outer ring spacer width B 1B1 determines:
(2)
The present invention has broken away from the on-the-spot narrow limitation cannot measured without platform, and easy and simple to handle, accuracy is high.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of marking before bearing clearance of the present invention adjustment.
Fig. 2 is the schematic diagram of step 3 bearing clearance of the present invention adjustment.

Add load block at cycle surface when b, measurement, its load value should ensure rolling element and raceway even contact;
Each row roller and lasso should be rotated respectively, to ensure that each part of bearing is all in normal position before c, measurement;
Step 3 bearing clearance adjusts
The adjustment of bearing axial play adopts the method for preparation outer ring spacer to adjust, namely the method for described preparation outer ring spacer is the determination of external spacerband width B1B1, press shown in Fig. 2 before measuring, axial distance a and b of inner ring end face to cycle surface is measured respectively by gauge block 1, size in position I and position II.
BB is determined by (1) formula:
（1）
If axial internal clearance is set to Ga, then B1B1 calculates by (2) formula:
Outer ring spacer width B 1B1 determines:
(2).
