Cylindrical gear is an important type of mechanical gear, and it is the most common gear style.
When the gear mechanism of cylindrical gear is meshed and transmitted, there is a large tangential relative sliding speed along the tooth length direction, which will produce a large rate of friction and wear; On the other hand, the tooth profiles of the two wheels are in point contact state, and the contact stress value will be very large, which will cause the surface to be pressed and fed too early and aggravate the wear of the teeth. Compared with parallel shaft helical gear, the service life and mechanical efficiency of staggered shaft helical gear mechanism are much lower.
Gear mechanism is used to transmit motion and power between two shafts. It is the most widely used transmission mechanism. It realizes the transmission requirements through the meshing of gear teeth. Therefore, compared with mechanical transmission such as friction wheel and belt pulley, its remarkable characteristics are: stable transmission ratio, reliable operation, high efficiency, long service life, and wide applicable diameter, circumferential speed and power range.
Cylindrical gear is an important type of mechanical gear, and it is the most common gear style. According to the direction of gear teeth, cylindrical gears can be divided into straight cylindrical gears, helical cylindrical gears and herringbone cylindrical gears.
