What is the number of teeth on a gear?
1 Answers
Generally, the number of teeth on a gear is taken as m≥2. Within the same gear group, gears with the same modulus should be used as much as possible; gears with different moduli are only used under special circumstances, such as the final expansion group or back gear group, but generally no more than two types. The principle for determining the number of gear teeth is: compact gear structure size and small spindle speed error. The following is a related introduction about gears: 1. Composition: Generally, it consists of teeth, tooth grooves, end faces, normal faces, addendum circles, dedendum circles, base circles, and pitch circles. 2. Introduction to components: Each protruding part used for meshing, these protruding parts are generally arranged radially, and the teeth on the paired gears contact each other, enabling the gears to continue meshing and operating; the tooth groove is the space between two adjacent teeth on the gear; the end face is the plane perpendicular to the axis of the cylindrical gear or cylindrical worm; the normal face refers to the plane perpendicular to the tooth line of the gear; the addendum circle refers to the circle where the top of the tooth is located; the dedendum circle refers to the circle where the bottom of the groove is located.
