Abstract
A kind of turntable shaft carries the determination method of play, first prepares outer ring size and is pre-designed equivalently-sized, has certain inner ring owing mill amount and be assembled into negative play bearing；Then holding shaft bearing outer-ring size constancy, is gradually reduced the deficient mill amount of bearing inner race, bearing corresponding moment of friction when measuring a certain deficient mill amount in elastic range, and draws the graph of a relation owing the increase of mill amount with moment of friction change；Owing to negative play and deficient mill amount are corresponding relation, therefore according to the graph of a relation drawn, draw the relation of negative play and moment of friction, thus realize determining according to moment of friction the negative play of turntable bearing.The present invention, by being characterized by deficient mill amount by negative play, then resettles the graph of a relation of deficient mill amount and moment of friction, draws deficient mill amount and the size of negative play intuitively by the moment of friction measuring turntable bearing.The method is simple and easy to do, and the accuracy measured is the highest.
Description
Technical field
The present invention relates to the turntable bearing of mechanical field, a kind of turntable shaft carries the determination method of play (the most pre-interference).
Background technology
The play of bearing is under normal circumstances more than zero, and requires motion occasion very smoothly at some, the turntable bearing used such as the occasion such as radar, blower fan, requirement realizes bearing negative play, i.e. play value is less than zero, and the size of negative play is owing to belonging to elastic deformation category, it is impossible to directly measure.
Summary of the invention
For solve existing turntable bearing negative play amount cannot problem measured directly, the invention provides a kind of turntable shaft and carry the determination method of play, indirectly characterize the negative play of turntable bearing by the moment of friction measuring turntable bearing.
The present invention solves that the technical scheme that above-mentioned technical problem uses is: a kind of turntable shaft carries the determination method of play, comprises the following steps:
1) according to the bearing outer ring dimensioned bearing outer ring being pre-designed, on the basis of the bearing inner race size being pre-designed, then increase certain additional size, to make, there is certain bearing inner race owing mill amount；
2) bearing outer ring utilizing step 1) to process and the bearing inner race with deficient mill amount are assembled into negative play bearing, and record deficient mill amount now and moment of friction；
3) holding shaft bearing outer-ring size constancy, bearing inner race is owed in regime of elastic deformation mill, thus is gradually reduced the deficient mill amount of bearing inner race, in the process, bearing corresponding moment of friction when measuring a certain deficient mill amount, then draws the corresponding relation figure owing mill amount with moment of friction；
4) it is corresponding relation due to negative play and deficient mill amount, the deficient mill amount therefore drawn according to step 4) and the corresponding relation figure of moment of friction, draw the relation of negative play and moment of friction, thus realization determines the negative play of turntable bearing according to moment of friction.
Deficient mill amount of the present invention refers to the actual size numerical value more than inner ring roller-way design size of inner ring roller-way.
Beneficial effect: the present invention, by being characterized by deficient mill amount by negative play, then resettles the graph of a relation of deficient mill amount and moment of friction, draws deficient mill amount and the size of negative play intuitively by the moment of friction measuring turntable bearing.The method is simple and easy to do, and the accuracy measured is the highest.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is further elaborated.
A kind of turntable shaft carries the determination method of play, comprises the following steps:
1) according to the bearing outer ring dimensioned bearing outer ring being pre-designed, on the basis of the bearing inner race size being pre-designed, then increase certain additional size, to make, there is certain bearing inner race owing mill amount；
2) bearing outer ring utilizing step 1) to process and the bearing inner race with deficient mill amount are assembled into negative play bearing, and record deficient mill amount now and moment of friction；
3) holding shaft bearing outer-ring size constancy, bearing inner race is owed in regime of elastic deformation mill, thus is gradually reduced the deficient mill amount of bearing inner race, in the process, bearing corresponding moment of friction when measuring a certain deficient mill amount, then draws the corresponding relation figure owing mill amount with moment of friction；
4) it is corresponding relation due to negative play and deficient mill amount, the deficient mill amount therefore drawn according to step 4) and the corresponding relation figure of moment of friction, draw the relation of negative play and moment of friction, thus realization determines the negative play of turntable bearing according to moment of friction.
The said method utilizing the present invention is possible not only to measure the negative play of existing turntable bearing, and the negative play turntable bearing meeting needs can also be designed, such as, need to design a negative play turntable bearing to meet needs, the method that the most just can use the present invention:
1) according to the bearing outer ring dimensioned bearing outer ring being pre-designed, on the basis of the bearing inner race size being pre-designed, then increase certain additional size, to make, there is certain bearing inner race owing mill amount；
2) bearing outer ring utilizing step 1) to process and the bearing inner race with deficient mill amount are assembled into negative play bearing, and record deficient mill amount now and moment of friction；
3) holding shaft bearing outer-ring size constancy, bearing inner race is owed in regime of elastic deformation mill, thus is gradually reduced the deficient mill amount of bearing inner race, in the process, bearing corresponding moment of friction when measuring a certain deficient mill amount, then draws the corresponding relation figure owing mill amount with moment of friction；
4) according to the moment of friction of turntable bearing when using, the deficient mill amount drawn in step 3) owes mill numerical quantity with finding out bearing inner race corresponding to this moment of friction in the corresponding relation figure of moment of friction, and owe the Internal and external cycle of mill numerical quantity processing bearing according to this, and then complete the assembling of negative play turntable bearing.
In order to measure accurately, during design bearing, outer ring processes according to normal dimensional parameters, realizes negative play by the size changing inner ring.
