Description

Technical Field

[0001] The utility model belongs to the technical field of tooling fixtures, and particularly relates to a special tooling for milling grooves on an active cylindrical gear. Background Art

[0002] A face gear is a face gear transmission device used for two intersecting shafts or two staggered shafts at a 90° angle or a non-90° angle, and is mainly applied to the face gear transmission of standard spur teeth or helical teeth in occasions with large loads and long-term use.

[0003] During the use of a face gear, friction will occur between the tooth surfaces, and a large amount of heat will be generated during the high-speed operation of the face gear. If the heat cannot be dissipated in time, the tooth surface temperature will rise, which will in turn affect the performance and service life of the gear. In order to improve the use effect of the face gear, an oil passage groove needs to be machined at the bottom of the tooth groove of the face gear, so that lubricating oil or coolant can flow smoothly into the bottom of the tooth groove, thereby forming a lubricating film between the tooth surfaces, effectively reducing friction and wear, and extending the service life of the gear.

[0004] In order to better machine the face gear and prevent the face gear from shaking during the machining process of the face gear, it is necessary to clamp and position the face gear. The existing working fixture for the face gear has a poor positioning effect on the face gear and cannot quickly and correctly position.
