Abstract
The present invention relates to a bearing assembly and measurement tool which is mainly characterized in that one end of the tool body is an assembly end, and the other end is a measurement end; the centre of the tool is provided with an annular positioning cylinder; the inner circumference surface of the annular positioning cylinder is provided with an annular support flange; the outer circumference surface of the annular positioning cylinder at the assembly end is provided with an annular assembly step with a support surface; an annular groove is formed between the annular assembly step and the annular positioning cylinder; and the outer cylinder surface of the annular positioning cylinder at the measurement end is provided with an annular measurement step with a support surface. The bearing assembly and measurement tool is simple in structure, small in size, light in weight and convenient to operate and use; the assembly end surface of the tool is upward, a bearing base is arranged on the assembly support surface, and thus assembly can be finished; the measurement end surface of the tool is upward, and thus measurement of axial play of a bearing can be finished; the assembly and measurement are good in reliability; assembly and play measurement of the bearing can be finished with one set of tool, thereby reducing production cost, reducing tool switching time and improving production efficiency; and economic efficiency is good.
Description
Technical field
The present invention relates to a kind of alignment measurement frock, be specifically related to a kind of bearing assemble for planetary wheeling assembly cylinder roller bearing in wind turbine gearbox and measure frock.
Background technology
Well-known in gear drive field, at present to assembling and the play measurement employing two cover frocks mostly of bearing, especially planetary wheeling assembly cylinder roller bearing assembling in wind turbine gearbox, wherein a set of frock is used for assembling, bearing clearance measurement is carried out by another set of frock after assembling completes, this not only increases the cost of fabricating tools, and production efficiency is obviously not high.For solving above-mentioned middle problem, reducing frock manufacturing cost, saving and exchanging the frock time, this just needs a kind of frock that can be used for assembling and can be used for measure.
Summary of the invention
Not only the object of the invention is the shortcoming that will overcome above-mentioned technology, provide a kind of structure simple, processing ease, good reliability, can be used for bearing assemble, but also can be used for the bearing assemble that bearing clearance measures and measure frock.
Bearing assemble of the present invention measures frock, comprises frock body, it is characterized in that: described frock body one end is assembling end, and the other end is measuring junction, and center is provided with circular orientation right cylinder; The cylindrical outer circumference surface of circular orientation of described assembling end is provided with annular assembling step, and annular assembling step is provided with annular assembling supporting surface, looping groove between annular assembling step and circular orientation right cylinder; The cylindrical external cylindrical surface of circular orientation of described measuring junction is provided with annular and measures step; Described annular is measured step and is provided with annular measurement supporting surface, and it is lower 5 ~ 10 millimeters than measuring end face that annular measures supporting surface, and the annular measurement step width measuring step is 5 ~ 10 millimeters.
In order to better realize above-mentioned purpose:
The assembling step width of described annular assembling step is 5 ~ 10 millimeters, assembling bench height is 5 ~ 8 millimeters.
Described annular assembling supporting surface is lower than assembled end 10 ~ 15 millimeters.
The measurement bench height that described annular measures step is 5 ~ 8 millimeters.
The cylindrical inner peripheral surface of described circular orientation is provided with annular support flange, and flange is wide is 3 ~ 5 millimeters,
Bearing assemble of the present invention measures frock, and structure is simple, volume is little, lightweight, easy for operation, and during assembling, upwards, bearing seat outer ring is placed in assembling supporting surface to the assembled end of frock, can complete assembling; When play is measured, only need by frock measuring junction towards upper, bearing seat inner ring is placed in measurement supporting surface, upwards mentions planetary gear, and the end-play that can complete bearing is measured, and alignment measurement is time saving and energy saving, good reliability; A set of frock just can complete assembling and the play measurement of bearing, reduces production cost, saves frock swap time, improve production efficiency, good economy performance.
