Question:

Is the gear a standard part?

Is the gear a standard part?

Answer:

It should be said that the design of the general gear follows the unified standard, and there is a unified algorithm to facilitate processing
Only the modulus and the number of teeth are required for the determination of the standard gear. After the gear modulus and the number of teeth are determined, according to the state regulations, the modulus and the number of teeth are brought into the formula, and the gear height, the pitch of teeth, the diameter of the pitch circle and the center distance of the gear are determined in turn, and the gear thus obtained is called a standard gear.
But in the gear design process, in order to reduce the number of processing gear cutter, the gear modulus set the national standard.
Standard gears and standard parts are two concepts. Gear does not belong to national standard parts, national standard parts have O- ring, washer and retaining ring, structural parts, nuts, bolts and screws, rivets and welding pins, seals, pins and keys, bearings.
