Gear grinding finishing: Generating gear grinding and forming gear grinding

Gear grinding finishing：The descriptions of generative tooth grinding and forming method tooth grinding are as follows, for reference and understanding.

1. Grinding teeth by developing method:

a. Grind teeth with a double bevel grinding wheel:

It is carried out on the conical surface grinding wheel gear grinding machine, the grinding wheel is trimmed into a conical surface to form the tooth surface of the imaginary rack, as shown in the figure.

b. Grind teeth with two disc-shaped grinding wheels:

Grind the teeth with two disc-shaped grinding wheels on a double-wheel gear grinding machine, which can produce high-precisionCylindrical gear, But the structure of the machine tool is complicated, the cost is high, the productivity is low, and the application is not wide.

As shown in the figure, the two disc-shaped grinding wheels are inclined at a certain angle to form the two outer sides of the two (or one) teeth of the imaginary rack, and the gear teeth are ground at the same time.

2. Gear grinding by forming method:

This method has high productivity, but is affected by the grinding wheel dressing accuracy and indexing accuracy, and the processing accuracy is low.

It is necessary to trim the two sides of the grinding wheel near the outer circle into a shape that matches the teeth of the workpiece, and then grind the teeth that have been cut.

Gear grinding is specially used for finishing hardened gears.MoregearFor technical questions related to gear grinding and finishing, you can consult EP free of charge.
