E tsamaellana le liprofaele tsa 3V, 5V, 8V tse nang le litekanyo tsa metric

E sebelisoa haholo lisebelisoa tsa indasteri tsa Europe

3. Litlhaloso tsa Theknoloji le Boitsebiso ba Boenjiniere

Litekanyo tse Bohlokoa

Paramethara	Tlhaloso	Tekanyo
Pitch Diameter	Diameter e sebetsang hantle	E lekantsoe moleng oa lebanta
Kantle Diameter	Bophara ba pulley ka kakaretso	Bohlokoa bakeng sa tumello ea bolulo
Bore Diameter	Boholo ba ho kenya shaft	H7 mamello e tloaelehileng
Botebo ba Groove	Sebaka sa ho lula lebanta	E fapana ho ea ka karolo ea lebanta
Hub Protrusion	Axial positioning reference	E netefatsa ho tsamaisana hantle

Litšobotsi tsa Ts'ebetso

Meeli ea Lebelo
Boholo ba RPM bo baloang ho ipapisitsoe le thepa le bophara

Cast iron: ≤ 6,500 RPM (ho itshetlehile ka boholo)

Tšepe: ≤ 8,000 RPM

Aluminium: ≤ 10,000 RPM

Bokhoni ba Torque
E khethoa ke palo ea li-groove le karolo ea lebanta

Mabanta a khale: 0.5-50 HP ka groove

Mabanta a moqotetsane: 1-100 HP ka groove

4. Mounting Systems le Tlhophiso

Litlhophiso tsa Bore

Plain Bore

E hloka senotlolo le li-screw tsa ho seta
