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

Is it Better to Repair or Replace a Damaged Gearbox?
Deciding whether to repair or replace a damaged gearbox depends on several factors and considerations:
- Extent of Damage: Assess the severity of the gearbox damage. Minor issues like worn bearings or seals may be repairable, while extensive damage may necessitate a replacement.
- Cost of Repair: Compare the cost of repairing the gearbox to the cost of replacing it with a new or remanufactured unit. In some cases, repairs might be more cost-effective.
- Availability of Parts: Availability of replacement parts for the gearbox can influence the repair option. If parts are hard to find, replacement might be a more viable choice.
- Age and Condition: Consider the age and overall condition of the vehicle. If the vehicle is older and nearing the end of its lifespan, a replacement gearbox might offer better long-term reliability.
- Performance and Efficiency: A new or remanufactured gearbox might offer improved performance and efficiency compared to a repaired one.
- Future Maintenance: Evaluate potential future maintenance needs of both repair and replacement options. A replacement gearbox might come with a warranty and require less frequent maintenance.
- Professional Assessment: Seek advice from a qualified mechanic or technician who can thoroughly assess the gearbox and provide recommendations based on expertise.
Ultimately, the decision to repair or replace a damaged gearbox should be based on a careful evaluation of these factors. It’s recommended to consult with professionals to make an informed choice that best suits your specific situation and budget.
