Product Description
>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

Can I Use Synthetic Oil in My Gearbox?
Yes, you can use synthetic oil in your gearbox, and in many cases, it can offer several advantages over conventional mineral-based oils:
- Improved Temperature Stability: Synthetic oils typically have a higher resistance to thermal breakdown, making them suitable for gearboxes that operate at high temperatures.
- Enhanced Lubrication: Synthetic oils often have superior lubrication properties, providing better protection against friction, wear, and component damage.
- Extended Oil Change Intervals: Synthetic oils can often withstand longer operating periods without losing their effectiveness, reducing the frequency of oil changes and maintenance.
- Reduced Viscosity Changes: Synthetic oils are less prone to viscosity changes at different temperatures, ensuring consistent lubrication performance in varying conditions.
- Lower Friction and Energy Loss: The smoother molecular structure of synthetic oils can lead to reduced internal friction, potentially improving gearbox efficiency and performance.
- Cold Weather Performance: Synthetic oils generally flow better at low temperatures, making them suitable for gearboxes operating in cold climates.
- Protection Against Oxidation: Synthetic oils often have better resistance to oxidation, helping to prevent the formation of sludge and deposits that can impact gearbox performance.
However, before switching to synthetic oil, it’s important to consider the manufacturer’s recommendations and specifications for your specific gearbox model. Some gearboxes may have specific requirements or restrictions on the type of lubricant to use. If the manufacturer approves the use of synthetic oil, it can be a beneficial choice, but if not, sticking to the recommended oil type is crucial to ensure proper gearbox function and warranty coverage.
