Sprocket manufacturers share: the difference between helical gears and spur gears

Sprocket manufacturers share: the difference between helical gears and spur gears

(Summary description)Through the introduction of the sprocket in the editor, I believe everyone has some understanding of the sprocket. Today, the sprocket manufacturer shares: the difference between helical gears and spur gears. If you want to understand it, come and understand it together with the editor.

1. The gear teeth of the helical gear drive are gradually driven in and out, and the spur gear drive is a period of time (very short) after the first pair of teeth leave, and the next pair of teeth are meshed, and the coincidence is greater than that of the spur gear. If the helical gear transmission is relatively stable, the spur gear transmission is prone to sudden vibration, which is not suitable for heavy load conditions;

2. Because the gear teeth are oblique, helical gear transmission can produce a certain amount of axial force during transmission. Therefore, helical gears can bear both radial force and axial force; spur gears are not enough. This point

3. The tooth bearing surface of the spur gear is distributed along the gear axis in the full tooth width, while the distribution of the helical gear tooth bearing surface in the gear axial direction cannot cover the full tooth width. According to this principle, the same modulus is the same Under the premise of the same number of teeth, the force of the helical gear will be less than that of the spur gear. However, the normal force capacity of the gear will be enhanced due to the helix angle of the helical gear;

4. Helical gears are smoother than spur gears. Because gear teeth are gradually meshed and separated, and the number of meshed teeth is relatively large, it can bear a larger load, but generates a certain axial force and has a longer life. In other words, helical gears are used in heavy loads and large impact occasions.

In summary:

The advantages of helical gears: smooth transmission, low noise, high transmission power, stable performance, and long service life, usually used in closed gears. Disadvantages: If the parts are slightly difficult to map.

Advantages of spur gears: convenient processing, suitable for a wide range of open gear drives, and easy surveying and mapping. Disadvantages: The accuracy is not high and the noise is slightly higher.
