The gear ratio is determined by the distance between the center of the gear and the contact point in the gear drive of the gear reducer. As in the containing two gear device, if a gear is two times the size of another gear, then the gear ratio is 2:1. in the modern gear motor in the gear using a method called the special involute tooth, this is because the tooth shape is a very important characteristic that they can maintain a constant speed ratio in two gear.
On the helical gear motor, the direction of the gear teeth and the gear surface to a certain angle. When the two teeth of the helical gear system are engaged, the contact point starts from one end of the tooth and gradually moves to the other end with the rotation of the gear until the full engagement of the two teeth.
The reduction of the motor is through this way of meshing, helical gears in the operation than the spur gear is stable, the noise is relatively small, so that almost all of the automobile gearbox is the use of helical gears. Because the gear teeth on the helical gear motor have a certain angle, the gears will be subject to certain pressure when they are engaged. Bevel gears also have a very interesting feature, that is, if the gear tooth angle appropriate, you can load them on a vertical axis, so that the meshing angle to 90 degrees.
