Generally speaking, helical gears are used in staggered shaft drives where the angle of intersection is equal to 90 degrees, while helical gears are used in parallel shaft drives.

The spiral bevel gear transmission has high efficiency, stable transmission ratio, large arc overlap coefficient, high bearing capacity, smooth and smooth transmission, reliable operation, compact structure, energy saving, space saving, wear resistance, long service life and low noise.

Among various mechanical transmissions, the transmission efficiency of spiral bevel gears is the highest, which has great economic benefits for all kinds of transmissions, especially high-power transmissions; the transmission parts of transmission parts required for transmitting the same torque are the most space-saving, than belts, The space required for chain drive is small; the spiral bevel gear transmission ratio is permanently stable, and the gear ratio is stable. It is often the basic requirement for transmission performance in the transmission of various types of mechanical equipment; the spiral bevel gear works reliably and has a long service life.

The biggest difference between the helical gear and the helical gear is that the helical gear has a helical shape (the helical gear tooth surface is not straight), and the helical gear tooth shape is a diagonal straight line which is the difference in appearance.

In application, the gear meshing of the helical gear is progressive, the noise is small, and the strength is high. For example, the spiral bevel gear is used on the angle grinder, which is mainly related to the advantages and disadvantages of the helical tooth and the curved tooth.
