Harmony Reducer CSF-32-30-2UH for Closed Slot Shaving Cutter

The Harmonic Drive Reducer CSF-32-30-2UH is mainly composed of three basic components: a wave generator, a flexible gear and a rigid gear. The harmonic drive reducer is a gear drive that uses a wave generator to make the flexible gear produce controllable elastic deformation and mesh with the rigid gear to transmit motion and power.

Product Description

For gears with a small number of teeth, in order to increase the overlap during shaving and improve the stability of the shaving process, the shaft angle should be appropriately smaller. When shaving shoulder gears and small gears of duplex gears, the shaft angle should also be smaller to avoid collision between the shaving cutter and the shoulder or large gear. In order to ensure the shaving effect. The minimum shaft angle cannot be less than 32° Increasing the number of teeth of the shaving cutter can increase the overlap during shaving, improve processing accuracy and extend the life of the shaving cutter. Therefore, under the premise that the function of the shaving machine allows, a larger number of teeth should be used as much as possible.

When determining the number of teeth of the shaving cutter actually used, the following factors should also be considered

1) There should be no common factor between the number of teeth of the shaving cutter and the number of teeth of the shaved gear

2) The shaving center distance should be within the range of use of the shaving machine.

3) The number of teeth selected should match the existing indexing plate groove number of the gear grinding machine as much as possible.

4) For ease of manufacturing, the number of teeth of small-module shaving cutters can be appropriately reduced.

The chip groove section of closed-groove shaving cutters also has two types: rectangular and trapezoidal. The former is easy to manufacture. But the cutting angles of the cutting edges on both sides are different; the latter is more difficult to manufacture, but the cutting angles of the cutting edges on both sides can be maintained. The bottom of the groove is usually a curved groove bottom parallel to the tooth surface, but it can also be made into a bevel groove bottom. At this time, the top and root have a standard groove depth to ensure the number of times the shaving cutter is reground, and the depth of other parts is greater than the standard value, which is conducive to chip holding without hindering the strength of the cutter teeth. This groove bottom shape is conducive to the processing of the chip groove.
