What is the difference between spur gear wpds70 reducer and helical gear wpds70 reducer? The difference between helical gear and spur gear of planetary wpds70 reducer 1. The difference in appearance can be seen from the above figure that the helical gear is placed on the cylindrical gear misplaced, while the spur gear is not misplaced. 2. The support of planet carrier is different. Oblique teeth need double support of planet carrier, and straight teeth are both
What is the difference between spur gear wpds70 reducer and helical gear wpds70 reducer
Difference between oblique teeth and straight teeth of planetary wpds70 reducer
1. Differences in appearance
As can be seen from the above figure, helical gears are placed on cylindrical gears in dislocation, while straight teeth are not placed in dislocation.
2. The planet carrier supports the planet differently
Helical teeth need double support of planet carrier, and straight teeth can be double support or single support
3. Different accuracy
The accuracy of oblique teeth is higher than that of straight teeth. In terms of the structure of planetary wpds70 reducer, the planet carrier of oblique teeth planetary wpds70 reducer needs double support structure to support, while the planet carrier of straight teeth planetary reducer can be single support or double support. Only in terms of accuracy, noise and efficiency, the single support of spur gear is far from the double support of spur gear. Compared with the helical planetary reducer, the double supported Spur Planetary reducer has higher accuracy because the helical accuracy is higher than the straight accuracy, so the accuracy of the helical planetary reducer will be higher.
4. The noise is different
The main disadvantage of spur gear planetary wpds70 reducer is that they will produce vibration. Whether due to design, manufacturing or deformation, some changes of involute shape may occur along the whole tooth surface at the same time. This will lead to a regular, once per tooth excitation, which is often very strong. The resulting vibration not only causes large load on the gear, but also causes noise. Therefore, the noise of straight teeth is greater than that of oblique teeth.
5. It is difficult and uneconomical to manufacture and assemble a large number of thin spur gears, so they are made into connected gears with teeth along the helix direction;
6. Unlike spur gears, helical gears cause poor axial force. However, the advantages in vibration and strength far outweigh the disadvantages caused by axial thrust and slightly increased manufacturing cost. Therefore, helical gear rather than spur gear is selected in reducer manufacturing.
