>Introduction
ZLYJ series Reduction Gearbox (speed reducer) is a transmission part for most single screw extrusion line, wihch also possesses high precision hard gear surface and thrust block designed. Designed with standard ZBJ19009-88, it combines well with most of machines from different suppliers. Also the gear and axis parts are made of high strength alloy steel with surface hardness HRC54~62. In the front end of hollow input axis there is large specification thrust bearing that will bear axial thrust force while the screw is working
>Applied Circumstance
1. All kind of extrusion & blowing machinery
2. High speed shaft rotation Speed <1500RPM
3. Working Environment Temp. -40~45°C, with temperature below 0°C, should pre-heat lubrication oil to above 0°C
>Major Technical Index
1. Output Speed: 16-100 RPM
2. Output Torque: Max.4300 Nm
3. Motor Power: 5.5-200 Kw
>Selection of Gearbox
1. Select speed ratio
e.g. input speed n1=1000rpm, output speed n2=70rpm, ratio i=n1/n2=14.28, should select ratio 14
2. Select model type according to input power
e.g. input power P=26kw, after checking form, 29kw>26kw, most ecomonic should be ZLYJ200
3. Select assemble type
as per actual use, select horizontal or vertical type
4. Calculate axial thrust Fa=π*Ds²*Ps/(4*1000)
e.g. Screw diameter Ds=75mm, Screw pressure Ps=26MPa
Fa=π*Ds²*Ps/(4*1000)=114.8kN
187kN>114.8kN, ZLYJ200 can bear the axial thrust and economic to select
5. Confirm connection size
6. Confirm cooling type

Belang fan smering yn Gearbox Performance
Smering spilet in krityske rol by it garandearjen fan de optimale prestaasjes, langstme en betrouberens fan gearboxen. Goede smering leveret ferskate wichtige foardielen:
- Ferminderet friksje en wearze: Smering foarmet in beskermjende laach tusken gear tosken, lagers, en oare bewegende komponinten, ferminderjen wriuwing en minimalisearje wear en tear.
- Heat dissipation: Lubricants helpe dissipate de waarmte generearre tidens gear operaasje, foar te kommen oververhitting en potinsjele skea oan komponinten.
- Noise Reduction: Adekwate smering kin lûd en trilling dampe produsearre troch gear meshing, wat liedt ta rêstiger en soepeler wurking.
- Sealing en Contaminant Previnsje: Smeermiddelen meitsje in barriêre dy't fersmoargingen lykas stof, smoargens en focht ôfslute, har yngong foarkomt en it risiko fan korrosysje en skea ferminderje.
- Ferbettere effisjinsje: Goede smering ferleget enerzjyferlies fanwege wriuwing, en ferbetteret de totale effisjinsje fan 'e gearbox.
- Ferlingde libbensdoer: Smering helpt foar te kommen foarriedige slijtage en falen fan komponinten, ferlinging fan 'e libbensdoer fan' e Fersnellingsbak en minimalisearje de needsaak foar kostbere reparaasjes of ferfangings.
- Optimale prestaasjes: Fersnellingsbakken wurkje binnen spesifisearre tolerânsjes as se goed smard wurde, en soargje derfoar dat se de bedoelde prestaasjes en funksjonaliteit leverje.
It’s essential to use the recommended lubricant type, viscosity, and change intervals specified by the gearbox manufacturer to ensure the best possible performance and longevity. Regular monitoring and maintenance of lubrication levels are crucial to preserving the health of the gearbox and its components.
