3.1 Model
The transmission is divided into AB type. Type A includes all or part of the basic code, frame size, combination code, reduction unit parameters, motor model, speed regulation code and assembly type code according to its different types: Type B includes the basic code, frame size, minimum output speed, motor model and speed regulation code according to its different types. 3.1.1 Type A
a: Basic code: ZH indicates horizontal structure, ZHF indicates flange installation structure; b. Combination code: used for derivative transmissions, W indicates the first derivative connected with a worm gear, B indicates the second derivative connected with a cycloidal pinwheel, and T indicates the third derivative connected with a TZS coaxial limit column gear; deceleration parameter code: composed of two digits, the first digit indicates the specification code, see Table 9, the second digit is the speed ratio code, c
see Table 10;
speed regulation code: D indicates electric speed regulation, the code is omitted for manual speed regulation; assembly type code: used for the first derivative transmission, indicating the corresponding assembly type. Note: the speed regulating handwheel can be installed on the upper part of the transmission, either on the left or on the right, and is omitted to simplify the model marking surface. Users can propose it when ordering or adjust it by themselves during use.
