The classification of synchronous gear transmission mainly has the following points:
1. According to purpose
(1) Synchronous belt drive for general industry The tooth profile is trapezoidal. Mainly used in various medium and small power machinery.
(2) High-torque synchronous belt drive The tooth profile is arc-shaped. Mainly used for heavy machinery transmission.
(3) Special specifications of synchronous belt drive to meet the special needs of certain machinery (such as automobile engines).
(4) Special purpose synchronous belt drive is suitable for special working conditions, such as oil resistance, temperature resistance, high resistance, low noise, special size, etc.
2. According to the tooth shape
(1) Trapezoidal tooth is the standard tooth profile of the same class belt of ISO and our date. The model and size parameters have been standardized.
(2) Arc gears There are currently corporate standards in various countries. It is expected that international and Chinese national standards will be produced soon.
3. According to specifications
(1) Modular system The basic parameter is the horizontal number M, and most of the various models and structures are determined according to the modulus. Since the 1960s, the scope of application
slowing shrieking.
(2) Pitch system The basic parameter is inch belt tooth pitch. Determine the corresponding model and structural parameters according to the pitch. The unit of measurement changed from the English system
Calculate. It is currently ISO and my country's national standard.
(3) DIN metric pitch system The basic parameter is the pitch of the metric belt teeth. It is difficult to set the German national standard.
