Shielded inductance coil
- Commodity name: Shielded inductance coil
- Description
-
Hobbing is a method of processing gears based on the principle of generating. The tooth transmission chain between the tool and the tooth blank must maintain the accuracy of motion according to a certain transmission ratio. However, these transmission chains are composed of a series of transmission components. Their manufacturing and assembly errors will inevitably concentrate and reflect on the end parts of the transmission chain during the motion transmission process, resulting in uneven relative motion and affecting the processing accuracy of the gear teeth. The variation in the common normal length is the largest error reflecting the uneven distribution of gear teeth, which is mainly caused by the uneven rotation accuracy of the worm gear pair of the hobbing machine's worktable, as well as the wear of the circular guide rail of the hobbing machine's worktable and the misalignment between the indexing worm gear and the circular guide rail of the worktable. Furthermore, severe collisions on the tooth surface of the indexing wheel or too loose or too tight engagement of the indexing wheel can also affect the excessive variation of the common normal.
