Description

Technical Field

[0001] The utility model relates to the technical field of RV reducer complete machine processing, in particular to a grinding tool for the output end of an RV reducer. Background Art

[0002] In RV reducers, the output flange is a key component for connecting transmission components and outputting high torque. Axial runout is a crucial indicator. The output flange consists of a long and short flange, each with a raceway. Strict runout requirements exist between the output end and the two raceways (generally 0.005-0.008mm). To achieve higher axial runout accuracy (≤0.001mm), the entire machine must be ground. Traditionally, a mandrel fixture is used. A 1:1000 taper mandrel is passed through the output flange assembly. The output end contacts the fixture end face, then transitions to the center hole. The other end is tightened with an end cap and nut. Hobbing is performed on a cylindrical grinder. Positioning methods allow only the initial distance between the end face and the raceway to be determined, and fit accuracy is affected by flatness. The 1:1000 taper mandrel determines the center of the center hole. During actual raceway grinding, the output flange end face and raceway are processed twice, resulting in double machining. Positioning accuracy is also affected by fixture accuracy.

[0003] During the processing of RV reducers and grinding fixtures, multiple bolts are usually required for fixing. For different models of RV reducers, it is often necessary to prepare matching bolts of different specifications in advance. Such an operation process not only requires the user to have an accurate understanding of the bolt specifications and sufficient preparation, but also during actual installation, it may be necessary to use special tools such as pressure plates to ensure that the bolts are tightened in place. The whole process is not only time-consuming, but also increases labor intensity. This inconvenience is particularly obvious. Furthermore, after completing the processing task, the user needs to invest the same time and energy to remove these bolts for subsequent maintenance, replacement of parts or reconfiguration of the working environment. This series of tedious operations undoubtedly brings additional workload to the user's daily work, reduces work efficiency, and also affects the overall operating experience. Therefore, we propose an RV reducer output end grinding fixture with easy-to-use functions, which is in urgent need of development. Utility Model Content
