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

Different Types of Gearboxes and Their Applications
There are several types of gearboxes, each designed for specific applications based on their characteristics and capabilities. Here are some common types and their applications:
- Spur Gearbox: Spur gearboxes consist of parallel-shaft gears with straight teeth. They are simple and economical, suitable for low-speed and low-torque applications such as conveyors, machine tools, and clocks.
- Helical Gearbox: Helical gearboxes have helical teeth that provide smoother and quieter operation compared to spur gears. They are used in various industries, including automotive, construction, and mining equipment.
- Bevel Gearbox: Bevel gearboxes transmit power between non-parallel shafts. They are commonly used in vehicles, marine applications, and heavy machinery where changing the direction of motion is necessary.
- Planetary Gearbox: Planetary gearboxes offer high torque density and compact size. They are used in robotics, automation, and precision machinery due to their efficiency and versatility.
- Worm Gearbox: Worm gearboxes have a worm screw meshing with a gear wheel. They provide high reduction ratios and are used in applications like conveyor systems, elevators, and packaging equipment.
- Cycloidal Gearbox: Cycloidal gearboxes use cams and pins for motion transmission, making them highly durable and shock-resistant. They find use in industrial machinery and robotics.
- Spiral Bevel Gearbox: Spiral bevel gearboxes combine the advantages of bevel and helical gears, providing high efficiency and smooth operation. They are employed in vehicles, aircraft, and machine tools.
Each type of gearbox offers specific advantages suited to its application, enabling efficient power transmission and control in various industries.
