Svaki model trokutastog pojasa specificira veličinu presjeka trokutastog pojasa. Veličina presjeka tipa trokutastog pojasa je: gornja širina je 13 mm, a debljina 8 mm; Veličina presjeka trouglastog pojasa tipa B- je: gornja širina je 17 mm, a debljina 10,5 mm; Veličina presjeka trouglastog pojasa u obliku C- je: gornja širina je 22 mm, a debljina 13,5 mm; Veličina presjeka trouglastog pojasa u obliku D-a je: gornja širina je 21,5 mm, a debljina 19 mm; Veličina presjeka trouglastog pojasa u obliku E- je: gornja širina je 38 mm, a debljina 25,5 mm. Odgovarajuće dimenzije (širina visina): 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.
