>Introduction
ZLYJ collection Reduction Gearbox (speed reducer) is a transmission element for most solitary screw extrusion line, wihch also possesses higher precision tough equipment area and thrust block made. Developed with standard ZBJ19009-88, it combines effectively with most of devices from various suppliers. Also the gear and axis components are manufactured of high strength alloy metal with floor hardness HRC54~62. In the entrance finish of hollow enter axis there is massive specification thrust bearing that will bear axial thrust force even though the screw is working
>Applied Circumstance
1. All kind of extrusion & blowing machinery
two. Large speed shaft rotation Pace <1500RPM
three. Operating Surroundings Temp. -forty~45°C, with temperature beneath 0°C, ought to pre-warmth lubrication oil to previously mentioned 0°C
>Major Specialized Index
1. Output Pace: 16-one hundred RPM
2. Output Torque: Max.4300 Nm
three. Motor Energy: 5.5-200 Kw
>Selection of Gearbox
one. Decide on pace ratio
e.g. input velocity n1=1000rpm, output pace n2=70rpm, ratio i=n1/n2=fourteen.28, should decide on ratio 14
2. Choose product variety in accordance to enter electricity
e.g. input electrical power P=26kw, right after examining kind, 29kw>26kw, most ecomonic must be ZLYJ200
three. Choose assemble kind
as per genuine use, choose horizontal or vertical variety
4. Calculate axial thrust Fa=π*Ds²*Ps/(4*a thousand)
e.g. Screw diameter Ds=75mm, Screw stress Ps=26MPa
Fa=π*Ds²*Ps/(4*one thousand)=114.8kN
187kN>114.8kN, ZLYJ200 can bear the axial thrust and economic to choose
five. Verify connection size
6. Verify CZPT sort

Gear reducers are also named reducers. Mechanical equipment, by either of these two names, are developed to reduce the energy transferred between the motor and the equipment among the rotational speeds (revolutions for each moment). The reducer efficiently decreases the rotational pace produced by the motor, therefore managing the velocity at which the equipment operates and rising the torque produced by the motor. Multiplying the torque produced by the motor will increase the machine’s obtainable electrical power – a approach known as “mechanical dominance”. In a greater context, gear reducers are essentially resources utilized to enhance the effectiveness of products procedure.
