How to choose gear module and number of teeth?

How to choose gear module and number of teeth?In fact, you can consider from the following aspects. If you are unclear or related to gear processing needs, you can consult EP for free.

1. The gear modulus needs to be related to your installation torque and load, and the modulus size is determined according to the use load. Select the standard value under the condition of meeting the structural size requirements and meeting the gear bending strength, and choose the smaller modulus.For the standard value of modulus, please click the previous article "Gear module"View related content.

2. The process given for gear design is to first calculate the modulus based on the contact strength, and then calculate the modulus based on the bending strength.

3. The modulus determines the bearing capacity of the gear and the size of the product. The smaller the modulus, the higher the transmission accuracy, and the larger the modulus, the higher the gear strength.

4. The number of teeth of the gear needs to be determined according to the speed of use, etc., which is calculated according to your transmission ratio.

5. The number of pinion teeth should avoid undercutting, and the number of meshing teeth should be prime to each other, and the need for matching and rounding the center distance should also be considered.

6. For open (semi-open) gear transmission, because the gear teeth are mainly worn out, in order to prevent the product from being too small, too many teeth should not be used for the pinion, generally z1=17~20.

7. Closed gear transmission generally has a higher speed. In order to improve the stability of the transmission and reduce the impact and vibration, it is better to have more teeth. The number of teeth of the pinion can be z1=20~40.

The above is the relevant description of the selection of gear modulus and tooth number, including but not limited to.Product selection needs to provide requirements such as modulus, number of teeth, materials, etc., and you can directly contact EP Gear processing Free consultation by technical staff.
