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

Steps to Replace a Faulty Gearbox in an Automobile
Replacing a faulty gearbox in an automobile is a complex task that requires proper tools, skills, and safety precautions. Here are the general steps involved in the process:
- Prepare the Vehicle: Park the vehicle on a flat surface and engage the parking brake. Disconnect the battery to ensure safety during the procedure.
- Drain Fluids: Drain the transmission fluid from the old gearbox into a suitable container.
- Disconnect Components: Remove any components obstructing access to the gearbox, such as the driveshaft, exhaust system, and linkage.
- Suspend the Engine: If necessary, use an engine hoist or support to suspend the engine safely.
- Support the Gearbox: Use a transmission jack to support the weight of the gearbox.
- Remove Gearbox: Detach the gearbox from the engine by removing bolts and disconnecting the clutch or torque converter.
- Install New Gearbox: Position the new gearbox onto the engine and secure it in place with bolts.
- Reconnect Components: Reattach the driveshaft, exhaust system, and linkage that were disconnected earlier.
- Refill Fluids: Fill the new gearbox with the appropriate transmission fluid according to the manufacturer’s specifications.
- Lower Engine: Carefully lower the engine back into its original position if it was suspended.
- Test and Adjust: Start the vehicle and test the new gearbox for proper operation. Check for any leaks, unusual noises, or gear shifting issues.
- Final Check: Double-check all connections and ensure that all components are properly secured.
- Dispose of Old Fluid: Dispose of the old transmission fluid safely and responsibly.
- Dispose of Old Gearbox: Properly dispose of the old gearbox according to local regulations.
It’s important to note that gearbox replacement can vary significantly depending on the vehicle’s make and model. It’s recommended to consult the vehicle’s service manual or seek professional assistance if you’re not experienced in automotive repair.
