Sonraíonn gach múnla den chrios triantánach méid na rannóige den chrios triantánach. Is é méid an ailt den chineál crios triantánach ná: is é 13mm an leithead barr agus is é 8mm an tiús; Is é méid na coda de chrios triantánach B-: is é 17mm an leithead barr agus is é 10.5mm an tiús; Is é méid na coda de chrios triantánach C-chruthach: is é 22mm an leithead barr agus is é 13.5mm an tiús; Is é méid na coda de chrios triantánach D-chruthach: is é 21.5mm an leithead barr agus is é 19mm an tiús; Is é méid na coda de chrios triantánach E-chruthach: is é 38mm an leithead barr agus is é 25.5mm an tiús. Toisí comhfhreagracha (airde leithead): 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.
