D.Tong.CALL cylindrical gear app for iPhone and iPad

APP mainly serves practitioners in the machinery industry or teachers and students majoring in machinery.
Cylindrical gear is an important type of gear in mechanical gear, but also the most common gear style.
When the gear mechanism of cylindrical gear meshing drives, there is a large tangential relative sliding speed along the tooth length direction, so it will produce a large rate of friction wear. On the other hand, the tooth profile of two wheels is in the point contact state, and the contact stress value will greatly cause the surface to be pressed prematurely, which will aggravate the tooth wear. Compared with parallel helical gears, the service life and mechanical efficiency of staggered helical gears are much lower.
Gear mechanism is the most widely used transmission mechanism used to transfer the movement and power between two axes. It is through the tooth meshing to achieve the transmission requirements, so compared with the friction wheel, belt wheel and other mechanical transmission, its remarkable characteristics are: stable transmission ratio, reliable work, high efficiency, long life, suitable for a wide range of diameter, circumference speed and power.
Cylindrical gear is an important type of gear in mechanical gear, but also the most common gear style. Cylindrical gear according to the direction of the teeth, it can be divided into straight gear, helical gear and helical gear.
