Each model of the triangular belt specifies the section size of the triangular belt. The section size of type a triangular belt is: the top width is 13mm and the thickness is 8mm; The section size of B-type triangular belt is: the top width is 17mm and the thickness is 10.5mm; The section size of C-shaped triangular belt is: the top width is 22mm and the thickness is 13.5mm; The section size of D-shaped triangular belt is: the top width is 21.5mm and the thickness is 19mm; The section size of E-shaped triangular belt is: the top width is 38mm and the thickness is 25.5mm. Corresponding dimensions (width * height): O (10 * 6), a (12.5 * 9), B (16.5 * 11), C (22 * 14), D (21.5 * 19), e (38 * 25.5).
The recommended groove angles of different types of pulleys in different diameter ranges are as follows: when the diameter range of O-type pulley is 50mm ~ 71mm, it is 34 degrees; 36 degrees at 71mm ~ 90mm and 38 degrees at > 90mm; Type a pulley is 34 degrees when the pulley diameter ranges from 71mm to 100mm and 36 degrees when the pulley diameter ranges from 100mm to 125mm; > 38 ° at 125mm; B-type pulley is 34 degrees when the pulley diameter ranges from 125mm to 160mm; 36 degrees for 160mm ~ 200mm and 38 degrees for > 200mm; C-type pulley is 34 degrees when the pulley diameter ranges from 200mm to 250mm, 36 degrees when 250mm to 315mm, and 38 degrees when > 315mm; When the diameter range of D-type pulley is 355mm ~ 450mm, it is 36 degrees, and when the diameter range is > 450mm, it is 38 degrees; Type E is 36 degrees when it is 500mm ~ 630mm and 38 degrees when it is > 630mm.
