Therefore, hard-toothed gears are increasingly used. The bearing capacity of the gear with the hard tooth surface is high, and the gear is subjected to quenching, surface quenching or carburizing and quenching treatment after semi-finishing cutting so as to improve the hardness. However, in the heat treatment, the gear inevitably undergoes deformation, particularly in the case of a large ring gear, and therefore grinding, lapping or finish cutting must be performed after the heat treatment to eliminate errors due to the deformation. However, when the reserved relative deformation of the grinding amount is small, the deformation of the gear ring cannot be eliminated during grinding, lapping or fine cutting.

At present, for high-precision hard tooth surface gear rings in China, a common process method is generally gear grinding. Because of the quenching treatment of the surface of the gear ring and the simple structure and thin wall of the outer ring of the gear ring, the deformation of the tooth part is large after the quenching treatment, the uneven side grinding amount of the tooth part is often caused, and the precision of the tooth part can not be finally ensured.

Detailed Description

For a better understanding of the present invention, reference will now be made in detail to the present invention, examples of which are illustrated in the accompanying drawings.

Example 1:

referring to fig. 1, the utility model provides an auxiliary workbench is rectified in easy deformation bull gear gerar grinding dress card. The tool comprises a correcting mechanism and a clamping mechanism. The gear ring 6 is fixed on the correcting mechanism through the closing mechanism, and the gear ring 6 is adjusted through the correcting mechanism so that the deformation of the tooth part of the gear ring 6 reaches the design tolerance. And the joint surface of the gear ring correction mechanism and the gear ring 6 needs to be ground, so that the flatness of the joint surface is ensured, and the correction reference of the gear ring 6 is ensured.

The utility model discloses a according to gear grinding equipment workstation structural design's auxiliary workbench, be equipped with aligning gear on the auxiliary workbench and to closing the mechanism, rectify the deformation of ring gear, also guarantee the ring gear and grind the even and design use accuracy requirement of product of volume in gear grinding processing, respond well. The utility model discloses rectify the ring gear, guarantee that it can carry out comprehensive finishing in order to reach the required precision of gear to profile of tooth and precision in the correct grinding process.

The utility model corrects the gear ring and clamps after quenching before gear grinding, adjusts the gear ring, and makes the deformation of the gear ring tooth part return to a reasonable range.
