>Introduction
ZLYJ collection Reduction Gearbox (velocity reducer) is a transmission portion for most solitary screw extrusion line, wihch also possesses substantial precision hard equipment surface and thrust block created. Developed with normal ZBJ19009-88, it brings together well with most of equipment from distinct suppliers. Also the gear and axis components are manufactured of high power alloy metal with surface hardness HRC54~62. In the front finish of hollow enter axis there is big specification thrust bearing that will bear axial thrust power while the screw is doing work
>Applied Circumstance
1. All type of extrusion & blowing equipment
2. High velocity shaft rotation Speed <1500RPM
3. Doing work Environment Temp. -forty~45°C, with temperature underneath 0°C, must pre-heat lubrication oil to earlier mentioned 0°C
>Major Technological Index
one. Output Speed: sixteen-one hundred RPM
two. Output Torque: Max.4300 Nm
three. Motor Electricity: 5.5-two hundred Kw
>Selection of Gearbox
one. Choose pace ratio
e.g. enter pace n1=1000rpm, output pace n2=70rpm, ratio i=n1/n2=fourteen.28, must choose ratio 14
2. Decide on product variety in accordance to input electrical power
e.g. input power P=26kw, right after examining type, 29kw>26kw, most ecomonic should be ZLYJ200
three. Select assemble sort
as per genuine use, select horizontal or vertical type
4. Compute axial thrust Fa=π*Ds²*Ps/(4*one thousand)
e.g. Screw diameter Ds=75mm, Screw pressure Ps=26MPa
Fa=π*Ds²*Ps/(4*a thousand)=114.8kN
187kN>114.8kN, ZLYJ200 can bear the axial thrust and economic to decide on
five. Confirm relationship measurement
6. Verify CZPT type

Gearboxes and reducers are enclosed mechanical reduction units commonly utilised in present-day automated control systems to command torque from your motors and accomplish other motion-related duties. A gearbox permits you to enhance torque even though reducing the speed of your key mover output shaft. The output shaft of the gearbox rotates at a slower pace than the enter shaft. This results in a mechanical benefit, rising torque. Conversely, your gearbox can be established in reverse, offering enhanced shaft speed and reduced torque. Two common transmission configurations are straight and correct angle. Online versions generally consist of helical or spur gears, planetary gears, cycloidal mechanisms, or harmonic generators. Right-angle styles generally use worm or helical equipment drives, however, hybrid drives are also available. Gearmotors merge an enclosed equipment established with an electric powered motor to increase torque and performance whilst minimizing speed. Even though further friction, inertia, or sharp load changes for limited-term operation of the actuator can cause issues, they supply a lengthy running daily life by protecting against overloading. Numerous equipment ratios, speeds and torques are obtainable to assist enhance functionality and decrease potential difficulties. Browse to locate the right gearbox and reducer for your automation task.
Planetary gearboxes are employed in a variety of occasions exactly where higher performance and high reduction ratio are essential in a small space. Showcasing high precision and substantial torque-to-quantity ratio, it is excellent for torque improve, deceleration, specific positioning and manage of regenerative equipment. To ensure that the selected planetary gearbox is the greatest suit for your software, it is essential to take into account parameters this kind of as torque, backlash and equipment ratios when picking a planetary gearbox.
