The above purpose is realized by the following technical scheme:

a gear measurement center tangential guide rail component clearance elimination structure comprises a fixed seat, a bearing plate, a locking screw, an adjusting spring and a connecting shaft, wherein the fixed seat is connected with the bearing plate through a hinge bracket, the fixed seat is in threaded connection with the adjusting screw and the locking screw, the adjusting spring is fixed at the front end of the adjusting screw, and the adjusting spring is inserted into a circular groove of the bearing plate;

the bearing plate is provided with a connecting shaft in a penetrating way, and the end part of the connecting shaft is connected with a bearing.

The gear measuring center tangential guide rail component anti-backlash structure is characterized in that the end part of the locking screw is inserted into a V-shaped angle of the bearing plate.

Has the advantages that:

1. the utility model discloses at the clearance between stable elimination tangential slide and the tangential guide rail in gear measurement center debugging and the testing process, improve the whole rigidity of gear measurement center tangential motion part to guarantee the precision and the stability of gear measurement center debugging and testing process, the effectual measurement of efficiency and the detection precision of having guaranteed the instrument.

2. The utility model discloses more convenient and quick realization gap eliminating function, the motion straightness accuracy of tangential part does not receive spring or bearing because the contact point error that processing or assembly arouse influences.

3. The utility model discloses clearance structure bearing and linear guide slider keep relative static, because linear guide slider is carrying out the primary motion when the tangential motion part motion, therefore the whole motion rigidity is compared traditional spring and is eliminated the clearance structure and is improved greatly.

4. The utility model discloses the precision is reliable, and the structure is clear and definite, has guaranteed more original design stable measurement of efficiency and detection precision in gear measurement center debugging and the testing process.
