(Summary description)When it comes to gears, the module must be inseparable, and the module is one of the two major factors that determine the size of the gear. So what is modulus? Before explaining, we need to understand another concept, that is, the index circle. The index circle is a circle with a certain diameter d between the gear circle and the tooth root circle. This circle becomes the index circle, which is used as a calculation gear. Reference for the dimensions of each part. The modulus is the ratio of the pitch of the index circle (the length of the index circle between equivalent points on two adjacent teeth) to the pi (π), in millimeters (mm). In addition to the modulus, there are CP (Circular pitch) and DP (diameter pitch) that indicate the size of the gear teeth.

Information

When it comes to gears, the module must be inseparable, and the module is one of the two major factors that determine the size of the gear. So what is modulus? Before explaining, we need to understand another concept, that is, the index circle. The index circle is between the gear circle and the root circle, and a circle with a certain diameter of d is specified, and this circle becomes the index. A circle, which is used as a benchmark for calculating the dimensions of each part of the gear. The modulus is the ratio of the pitch of the index circle (the length of the index circle between equivalent points on two adjacent teeth) to the pi (π), and the unit is millimeters (mm). In addition to the modulus, the size of the gear teeth is represented by CP (Circular pitch) and DP (Diametral pitch)

We are serious about producing precision small module gears!
