Measuring tooth typeCouplingThe internal and external teeth should be combined with 20 degrees and 30 degrees pressure angle teeth.CouplingThe structure must be combined with the tooth formula to determine the product size, and the company's technology will help you get it!There are many ways to connect the teeth. Generally speaking, there are two types of couplings for transmission parts, involute splines with a pressure angle of 2 degrees and ordinary teeth of 30 degrees.According to the formula, the spline is-the number of teeth plus 20 multiplied by the modulus is equal to the outer diameter of the shaft head, and the number of teeth minus 1 is multiplied by the modulus to equal the diameter of the inner tooth.Ordinary teeth are the number of teeth plus 1 or minus 2 to multiply the modulus!Look at the actual picture tooth structure:
