Processing methods and guidelines of gear manufacturers:

1.磨齿:IT6~IT4→IT3,Ra:0.8~0.2μm原理:成形法和展成法。

⑴Forming method grinding teeth IT6~IT5, Ra: 0.8~0.4μm, grinding with a forming wheel, the gear transmission yield is higher, the machining accuracy is lower, and the application is less.

⑵Grinding teeth by developing method

Cone grinding wheel gear grinding: the section tooth profile of the grinding wheel is the tooth profile of an imaginary rack, and the workpiece is rolled to the right. The right side of the grinding wheel is used to grind the right side of 1 tooth groove from the root to the top; then the workpiece is rolled to the left, Grind the left side of the first tooth slot with the left side of the grinding wheel, and also grind it from the root to the top. When both sides of the first tooth slot are completely ground, the grinding wheel will automatically move away from the workpiece, and the workpiece will rotate by indexing. Roll to the right to grind the second tooth slot, and repeat this cycle until all the teeth are ground.

2. Grind teeth:

IT7~IT6, Ra: 1.6~0.2μm Equipment: Gear grinding machine.Abrasive: Abrasive grain: 220#~240#, active lubricating oil characteristics: the same as honing, can only reduce the surface roughness, can not improve the accuracy of the tooth profile.

Parallel axis grinding method:

1. Process: The grinding wheel is parallel to the axis of the gear being ground. During grinding, the grinding wheel drives the grinding wheel to make a free meshing motion without backlash. The gear being researched also makes axial reciprocating motion, and the grinding wheel is slightly braked.After a period of time, the grinding wheel and the grinding wheel rotate in opposite directions, so that the two sides of the teeth are evenly ground.

2. Features: Due to the uneven sliding speed of the tooth surface, the grinding amount is also uneven, the sliding speed at the tooth tip and the tooth root part is large, and the grinding amount is also large.

Gear transmission with moving axis

There are many types of planetary gear transmission, and the performance of different types is very different. It is very important to choose the type reasonably according to the working conditions.Commonly used are ordinary planetary transmission composed of sun gear, planetary gear, internal gear and planet carrier, planetary gear transmission with small tooth difference, cycloid pin gear transmission and harmonic transmission.Planetary gear transmission is generally composed of parallel shaft gears. It has the characteristics of small size and light weight. The input shaft and output shaft can be on the same straight line.Its application is becoming more and more extensive.
