Single Screw ZLYJ Series Plastic Extruder Gearbox Reducer ZLYJ173/200/225/250

ZLYJ series reducer is a high-precision gear transmission device with a hard tooth surface and thrust package designed for plastic and rubber screw extruders. The product design refers to various technical specifications specified in JBT8853-2001 Cylindrical Gear Reducer. Its feature is that the gear and shaft parts are high-strength alloy copper. The accuracy of gear machined by carburizing, quenching, and gear grinding process is Gb10095-886. Tooth surface hardness HRc54-62. The front end of the hollow output shaft is equipped with a large-sized thrust bearing to bear the axial thrust when the screw is working. The machine has a small size, high bearing capacity, stable transmission, low noise, and high efficiency.

1. The speed of the high-speed shaft shall not be greater than 1500 rpm.
2. The peripheral speed of gear transmission shall not be greater than 20m/s.
3. The working environment temperature is - 40-45 ℃. If it is lower than 0 ℃, the lubricating oil should be preheated to above 0 ℃ before starting. This reducer can run in both positive and negative directions, but some models have one-way high-speed shafts. The default direction of the oil pump is clockwise rotation facing the output shaft. If the direction changes, please explain it when ordering.

Models of Plastic Extruder Gearbox

ගන්න  ZLYJ 225-12.5-Ⅰ(Ⅱ, Ⅲ, Ⅳ, Ⅴ, Ⅵ, Ⅶ, Ⅷ) උදාහරණයක් ලෙසය

ZLYJ: Reducer series model
225: Specification No
12.5: Nominal transmission ratio
Ⅰ: Assembly type

How to select the appropriate model

The mechanical power, axial thrust and thermal power must be checked for the selection of ZLYJ reducer. The detailed steps are as follows:

  1. Selection ratio (Table 1 )
    Input speed n1=1000pm, output speed n2=70 rpm
    i=n1/n2=1000/70=14.28, Selection ratio 14
  2. Specification of gear selection reducer (Table 1)
    Select the model according to the input power and output speed provided by the user.
    Input power P=26KW, 29KW>26KW, and the most economical, select ZLYJ200
  3. Assembly type of reducer (Fig. 1)
    Select the assembly type of the reducer according to the installation mode of the user.
  4. Calculated axial thrust Fa=xds PS/(4 x 1000)
    Screw diameter: ds=75mm    Screw pressure: PS=26MPa
    Thrust Fa=mx75 × 26/(4 × 1000)=114.8KN
    187KN>114.8KN, ZLYJ200 can withstand this axial thrust
  5. Clearance connection size (Figure 1, Table 2)
    Check the hole diameter, key width, spline parameters and shaft hole depth of hollow output shaft.
    Check the size of the anchor mounting hole and the size of the thrust package threaded hole
  6. Constant cooling mode (Table 3)
    Small size reducers are generally splash lubricated and naturally cooled.
    Large reducer adopts forced lubrication and cooler cooling. If the user requires configuration beyond the attached table, it must be stated when ordering.
