Spiral bevel gears are divided into two types. In the helical gear according to the tooth length direction of the teeth, there are spur gears and curve gears. Their division is mainly based on the line of intersection between the ruler contour and the truncated cone. If the contour of the ruler is a straight line at the intersection of the truncated cone, then it is a spur gear. If the contour of the ruler and the intersecting line of the truncated cone is a curve, then it is a curve gear. The difference in the curve also divides the helical gear into three categories.
Spiral bevel gear is mainly used in the transmission of automobile drive axle, tractor and machine tool.
Compared with the straight bevel gear, the transmission is smooth, the noise is small, the carrying capacity is large, the transmission power is less than 750Kw, but the axial force is larger due to the helix Angle. The speed is generally greater than 5m/s, and can reach 40m/s after grinding.
When choosing helical gear, you can choose different helical bevel gear according to your needs. Be sure to choose high quality or helical gears produced by well-known companies, which can improve the efficiency of mechanical operation.
1. Advantages of spiral gear
Compared with ordinary gears, the transmission of spiral bevel gears is more stable, and the noise in the transmission process is relatively low. It has a high carrying capacity. Smooth transmission process, compact structure, reliable work, and can save space. The wear life is longer than that of ordinary gear. It can be said that the transmission efficiency of the helical gear is all the teeth
2. Application of spiral gear
According to the characteristics of spiral bevel gear, its application range is also different. The application of curve gear is more extensive than that of spur gear, mainly because of its carrying capacity. It is higher than the curve gear, and the noise is low in the working process, and the transmission process is smooth. It has a long life and is used in aviation, Marine, and automotive industries.
3. Classification of helical gears
Spiral bevel gear is generally divided into straight gear, helical gear, curve gear. This is mainly based on the different types of gear rotation of his intersecting axis and staggered axis, according to the characteristics of its tooth length curve. The helical gears are classified according to the form machining methods of tooth height. Different helical gear processing methods are also different.
