| Arc of contact θ | I-angle lapho i-belt itsintsa khona i-pulley. Ibalulekile ku-pulley lencane; ngaphansi kwa-180° yehlisa emandla (i-factor Kα). |
| Banded belt | Ema-V-belt lamanyenti lahlanganiswe yi-band, ekushaywa nekuvimbela kuphenduka. |
| Bottoming | I-belt itsintsa phansi ku-groove: i-groove lesigugile nobe sekhishini lengasiyo. Kudala i-slip. |
| Centre distance C | Libanga emkhatsini wemkhatsi wema-shaft lamabili. |
| Cogged / notched | I-belt lenemanochi ngaphansi kute igobe kalula kuma-pulley lamancane futsi ipholile. |
| Datum diameter / datum length | I-diameter ye-pulley lesetjentiselwa kubala nebudze be-belt lobufanako, ku-datum line. Kusetjentiswa kuko konkhe kubala kwema-belt e-ISO. |
| Datum width | Bubanti be-groove (ne-belt) ku-datum line: 8.5, 11, 14, 19 mm ku-Z/SPZ, A/SPA, B/SPB, C/SPC. |
| Deflection force | Emandla ladzingekako kucindzetela i-belt eceleni nga-1/64 ye-span yayo; asetjentiselwa kucinisa nekuhlola kucina. |
| Design power Pd | Emandla e-motor × service factor. |
| Driver / driven | I-pulley ye-motor / i-pulley yemshini. |
| Effective length | Budze ngaphandle kwe-belt (ema-RMA narrow belt, poly-V). |
| Effective pull Te | Umehluko wekucina (licala lelicinile kususa lelikhululekile) lodlulisa emandla: Te = 1000 P / v. |
| Groove angle β | I-angle ye-groove ye-pulley, cishe 32–38° kuye nge-sekhishini ne-diameter. |
| Idler | I-pulley lejikeleta ngekukhululeka lesetjentiselwa kususa kukhululeka nobe kwenyusa i-arc of contact. |
| Kα (arc correction factor) | Yehlisa emandla e-belt kuma-arc langaphansi kwa-180°. |
| KL (length factor) | Ilungisa emandla e-belt ngebudze bayo. |
| Matched set | Ema-belt lentiwe nobe lakhetfwe ngebudze lobufanako kute ahlanganyele umtfwalo ku-drive lenema-belt lamanyenti. |
| Pitch (ema-timing belt) | Libanga emkhatsini wemazinyo, sib. 8 mm ku-HTD 8M. |
| Raw-edge | I-belt lenetinhlangotsi letisikiwe letingenalo lindvwangu kute ibambe kakhulu. |
| Rim speed | Lijubane le-pulley ngaphandle: kunemikhawulo ku-cast iron (≈ 30 m/s). |
| Service factor | Linani lelikhulisa ngenca yekushaywa, i-torque yekucala nema-awa ekusebenta. |
| Slip | Kulahleka lokuncane kwelijubane kwe-V-belt (≈ 1–2 %); i-slip lenkhulu idala kushisa nekuguga. |
| Span length | Budze be-belt lobukhululekile emkhatsini wema-tangent point ema-pulley. |
| Static (installation) tension | Kucina kwe-belt nayingasebenti, lokubekwa ekufakeni. |
| Synchronous belt | I-timing belt: inemazinyo, ayi-slip. |
| Take-up | Kulungisa lokukhona kute ucinise i-belt njengoba ihlala futsi inwebeka. |
| Taper-lock bush | I-bush legobile lesikiwe lebopha i-pulley ku-shaft; kushintja i-bush kushintja i-bore. |
| Teeth in mesh | Linani lemazinyo e-timing belt labambene ku-pulley lencane; gcina ≥ 6. |
| Tight side / slack side | Licala lelidonswa yi-pulley leshayelako / licala lelibuyako. |
| Turnover | I-V-belt iphenduka ku-groove yayo. |
| VSD / VFD | I-variable-speed (frequency) drive lelawula lijubane le-motor. |
| Wedge belt | I-narrow V-belt (SPZ–SPC, 3V/5V/8V) lenemandla lamanyenti nge-belt ngayinye. |
