What are the methods for gear manufacturers to repair gear tooth surface wear?

Gears are widely used, especially when modern mechanical equipment is widely used, users have a higher demand for gears. We should be very familiar with gears. Gears will inevitably be subject to different degrees of wear during operation. When the wear is not serious, we can repair it by this method for further use.

1. Adjust the transposition method: transpose the worn gear, and continue to work at the part where the gear is not worn or slightly worn.

2. Modification cutting method: remove the corresponding value of the scrapped large gear outer diameter lathe, and then roll the gear again, remove the corrosion part of the tooth surface, negative modification of the large gear, positive modification of the small gear, and become a new gear pair with unchanged transmission parameters, so that the large gear can be repaired and put into use.

3. Tooth inlay repair method: For gears with small load and low speed, during the repair process, the root of the bad gear shall be dug out of the trapezoidal groove on the planer, pressed into a new tooth germ with the same groove shape, welded firmly or connected with bolts for shaping.

4. Surfacing repair method: if the wear of individual gears or the wear of both sides of the gear ends exceeds the limit, one or more layers of metal can be overlayed on the whole or part of the gear surface according to the gear damage. Overlay welding repair gear, simple operation, good repair quality.

According to the above introduction, we can know that there are many ways to repair gear tooth surface wear, and we can choose more convenient repair methods according to our actual situation. But we need to know that only when the gear is not seriously worn can we continue to use it. If the gear is seriously worn, we can only replace it with a new one.
