Precision gear is a widely used mechanical part. In many industries, we pay more attention to the stability of precision gear. So how to deal with the tooth direction error of precision gear?

The tooth direction error is the end face distance between the two main design tooth lines on the indexing cylindrical surface and within the tooth width, which contain the actual tooth line and have a smaller distance. It directly analyzes the contact accuracy of gears through influence, which is one of the important inspection items of gears.

Due to the limitation of current gear production technology, the existence of gear direction error is actually inevitable. Most gear manufacturers use the gear production method mainly hob. Due to the long production time and the relatively mature technology of operators, it has become a habit for long-term use. Due to the high replacement cost of gear processing equipment, the manufacturer is unwilling to bear, which has exposed the shortcomings of this technology, but there are no regulations. Therefore, the correction of gear error can only be solved by empirical technology.

In the process of helical gear processing, the causes of tooth alignment error produced by gear manufacturers when producing gears are complex, sometimes it may be one reason, sometimes it may be multiple reasons, and the influence degree of each reason is different. Therefore, if gear manufacturers want to have no tooth alignment error at all, they should pay more attention to formulating reasonable processing technology in each process link, The error is controlled as small as possible, so as to reduce the tooth direction error out of tolerance to a certain extent and improve the product qualification rate.

The above is an introduction to the treatment of tooth direction error of precision gear. If you need precision gear, you are welcome to consult IHF combined gear manufacturer.
