The gear is a very important accessory of the whole reducer.During operation of the equipment, the cogs and cogs are effectively interlocked.Therefore, in order to use the equipment effectively, each accessory must be properly designed.Especially the gears.However, the following principles should also be followed when designing:
1. 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 check whether the bending fatigue strength of the tooth root meets the required 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 the open transmission: only calculate the bending fatigue strength of the tooth root, appropriately increase the modulus and reserve the wear amount to meet the contact fatigue strength of the tooth surface.
3. Generally, the reducer should first calculate the pitch circle diameter and main geometric parameters of the gear according to the contact fatigue strength condition of the tooth surface, and then check the bending fatigue strength of its gear teeth.When using a hard tooth surface, usually the gear modulus and its main geometric parameters should be determined according to the bending fatigue strength condition of the gear, and then the contact fatigue strength of the tooth surface should be checked.
You can imagine the importance of gears to reducers.It can be seen that the above principles should also be followed when designing gears.The precision, size, diameter and other data of the gears are all part of the design process that must be carefully planned to increase the efficiency of the equipment.
