Guomao ZLYJ extruder reducer

Guomao ZLYJ extruder reducerOverview

The reducer used in Guomao ZLYJ extruder belongs to the extruder reducer, abbreviated as ZLYJ extruder reducer. It is a high-precision hard toothed belt thrust pack gear transmission device designed for plastic and rubber screw extruders. The product design refers to the technical specifications specified in JB/T8853-2001 "Cylindrical Gear Reducer". Its characteristics have many similarities with ZLY hard tooth surface gear reducers, and the gears and shaft parts are made of high-strength alloy steel materials. Gears are processed through carburizing, quenching, and grinding processes. The gear accuracy is GB10095-88, level 6. Tooth surface hardness HRC54~62. A large-sized thrust bearing is installed in the front section of the hollow output shaft to withstand the axial thrust during screw operation. The ZLYJ reducer has the characteristics of small size, high load-bearing capacity, smooth transmission, low noise, and high efficiency.

How to choose a reducer for Guomao ZLYJ extruder (related questions refer to: Hard tooth surface reducer selection method)

The selection of ZLYJ reducer must verify the mechanical power, axial thrust, and thermal power, which are divided into six steps

Step 1: Choose Speed Ratio

Step 2: Select gearbox specifications

Step 3: Choose the assembly form of ZLYJ reducer

Step 4: Calculate axial thrust

Step 5: Determine the connection size

Step 6: Determine the cooling release method

Cooling method of Guomao ZLYJ extruder reducer (related reference: What lubricating oil is used for lubrication and cooling of gear reducer)

ZLYJ112~146 are naturally cooled

ZLYJ173~280 are cooling coils (internal cooling)

ZLYJ315~450 is a cooler for cooling

How to install the reducer for Guomao ZLYJ extruder

Attention should be paid to moisture prevention during transportation and storage of ZLYJ reducers; Should be installed on a flat surface; Inject lubricating oil to the centerline of the oil gauge.

When the oil temperature of the ZLYJ extruder reducer significantly increases (related reference: ZLYJ reducer working temperature increases) and the noise of the ZLYJ reducer is obvious during operation, it should be stopped and the cause should be checked. If it is caused by tooth surface adhesion or other reasons, it must be repaired and the fault must be eliminated. The lubricating oil of the ZLYJ reducer should be replaced before use.
