Abstract
The utility model relates to a tool for measuring installation clearance for a bearing of a wind power gear box. The tool comprises a support flange, an auxiliary measurement ring and a simulation spacer sleeve. The bearing surface of the support flange is a plane, and the auxiliary measurement ring and the simulation spacer sleeve are both shaped like a circular ring. Upper and lower surfaces of the auxiliary measurement ring and the simulation spacer sleeve are parallel planes. The external diameter of the simulation spacer sleeve is smaller than the internal diameter of the auxiliary measurement ring. The thickness of the simulation spacer sleeve is smaller than the thickness of the auxiliary measurement ring by 1mm. The tool has advantages that: the tool utilizes the auxiliary measurement ring and the simulation spacer sleeve to replace a depth gauge for measurement, measurement time is substantially shortened, measurement accumulative errors are reduced, assembling requirements are ensured, and production efficiency is raised.
Description
Technical field
The utility model relates to a kind of for wind power gear axle box bearing installation play measurement frock, belongs to the frock field of measuring.
Background technology
It is 20 years that the used bearing of wind turbine gearbox requires design service life, and split bearing is all at a high speed, move under the heavy duty, variable load operating mode, and control requires very strictly to the bearing assemble play, and the bearing after the assembling must meet design requirement.Axial play was 0.4-0.6mm after bearing in the one-level planetary wheeling assembly required bearing to install, if do not meet the serviceable life that designing requirement will have a strong impact on the one-level planetary gear after installing.Existing survey instrument only adopts pit gauge to measure respectively the inside and outside circle height value of bearing, and there are play in bearing self rolling body and bearing inner race rib, measure very difficultly, and it is large to measure cumulative errors, can not effectively guarantee the axial float of bearing after the assembling, inefficiency.
Summary of the invention
The purpose of this utility model is in order to overcome the problems referred to above, provide a kind of the wind power gear axle box bearing that is used for that can reduce to measure cumulative errors, shorten Measuring Time, enhance productivity play measurement frock to be installed.
The technical scheme that realizes the utility model purpose is as follows:
The utility model comprises pivot flange, subsidiary ring, simulation spacer, it is characterized in that: the supporting surface of pivot flange is the plane, subsidiary ring and simulation spacer are annular, the above and below of subsidiary ring and simulation spacer is the plane that is parallel to each other, the external diameter of simulation spacer is less than the internal diameter of subsidiary ring, the simulation spacer thickness than the little 1mm of thickness of subsidiary ring.
Good effect of the present utility model: the utility model replaces pit gauge to measure with simulation spacer and subsidiary ring, has greatly shortened Measuring Time, reduces and measures cumulative errors, guarantees matching requirements, has improved production efficiency.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
With reference to accompanying drawing, the utility model comprises pivot flange 1, subsidiary ring 2, simulation spacer 3, the supporting surface of pivot flange 1 is the plane, subsidiary ring 2 and simulation spacer 3 are annular, the above and below of subsidiary ring 2 and simulation spacer 3 is the plane that is parallel to each other, the external diameter of simulation spacer 3 is less than the internal diameter of subsidiary ring 2, simulation spacer 3 thickness than the little 1mm of thickness of subsidiary ring 2.
Particularly, the diameter of the supporting surface of pivot flange 1 is greater than the inner ring diameter of measured bearing, race diameter less than measured bearing, the external diameter of subsidiary ring 2 equates with the outer ring external diameter of measured bearing, wall thickness is identical with the wall thickness of measured bearing outer ring, the external diameter of simulation spacer 3 equates with the inner ring external diameter of measured bearing, wall thickness is identical with the wall thickness of measured bearing inner ring, first a row bearing band jump ring is faced down and be placed on (spring bearing inner ring) on the pivot flange, to simulate spacer 3 again, subsidiary ring 2 is placed on respectively in the bearing, on the outer ring, place again another row bearing (band jump ring end face upwards), make subsidiary ring 2, simulation spacer 3 is concentric with measured bearing, detecting between bearing and the simulation spacer 3 apart from (measuring error 0-0.02mm) with the clearance gauge circumference is A, simulation spacer 3 gauges are B, drawing match grinding part thickness value is: C=A+B-0.5mm, above measured value all needs record data.Then according to measured value bearing inner race is adjusted, guaranteed that bearing installation play meets designing requirement.After adopting frock of the present utility model, measure bearing the play time shorten is installed, measure cumulative errors and reduce, can effectively guarantee designing requirement, improved greatly assembly quality and the efficient of bearing.
