The gear is a very important accessory for the entire reducer. During the operation of the equipment, the gears and gears are actually in a state of interlocking with each other. Therefore, in order to use the equipment efficiently, it is necessary to carry out a reasonable design for every accessory. Especially at the gears. However, the following principles should also be adhered to when designing:
1. In closed transmission: the soft tooth surface should be designed and calculated according to the contact fatigue strength of the tooth surface to determine the parameters and dimensions of the gear, and then the bending fatigue strength of the tooth root should be checked to meet the bending fatigue strength of the tooth root.
2. The hard tooth surface of the reducer should be designed and calculated according to the bending fatigue bending strength to determine the parameters and dimensions of the gear, and then check the contact fatigue strength of the tooth surface. In open transmission: only calculate the bending fatigue strength of the tooth root, increase the modulus appropriately and reserve the amount of wear to meet the contact fatigue strength of the tooth surface.
3. Generally, reducer should first calculate the index circle diameter and main geometric parameters of the gear according to the contact fatigue strength conditions of the tooth surface, and then check the bending fatigue strength of its gear teeth. When a hard tooth surface is used, generally the gear modulus and its main geometric parameters should be determined according to the gear's bending fatigue strength conditions, and then the tooth surface contact fatigue strength should be checked.
The importance of gears to the reducer can be imagined. From this it can be seen that the above principles should also be adhered to when designing gears. Gear accuracy, size, diameter and other data are all part of the design process that should be carefully planned, so as to improve the efficiency of the equipment.
