China Custom CZPT 200 Gearbox for Profile Pipe Extruder Equipment bevel gearbox

Product Description

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

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

How to Choose the Right Gearbox for Your Machinery

Selecting the appropriate gearbox for your machinery involves careful consideration of several key factors. Here's a step-by-step guide to help you make the right choice:

1. Identify Application Requirements: Understand the specific requirements of your machinery, including torque, speed, load, direction of rotation, and duty cycle.
2. Choose Gear Type: Determine the type of gears that best suit your needs, such as spur, helical, bevel, planetary, or others, based on factors like efficiency, noise level, and space constraints.
3. Calculate Gear Ratio: Calculate the required gear ratio to achieve the desired output speed and torque. Consider factors like input and output shaft speeds.
4. Select Gear Material: Choose appropriate gear materials based on factors like durability, wear resistance, and corrosion resistance. Common materials include steel, cast iron, and various alloys.
5. Consider Efficiency: Evaluate the gearbox's efficiency and select one that meets your energy efficiency requirements.
6. Account for Load Conditions: Analyze the load conditions, such as constant or intermittent loads, shock loads, and starting and stopping frequencies.
7. Check Lubrication Requirements: Consider the lubrication needs of the gearbox and ensure proper lubrication for smooth operation and longevity.
8. Factor in Space Constraints: Consider the available space for installing the gearbox and choose a size that fits within your machinery.
9. Assess Environmental Conditions: Evaluate the operating environment, including temperature, humidity, and exposure to dust or corrosive substances.
10. Review Mounting Options: Determine the mounting options that work best for your machinery, such as foot-mounted, flange-mounted, or shaft-mounted gearboxes.
11. Consult with Experts: Seek advice from gearbox manufacturers or engineers to ensure you make an informed decision.

Choosing the right gearbox is crucial for achieving optimal machinery performance, longevity, and reliability.
