ZLYJ series Gear box plastic extrusion machinery, single screw
extruder gear box ZLYJ gear box reducer for plastic
machinery
I. Introduction:
ZLYJ series reducer is specially designed high precision
hardened gear transmission equipment for plastic, rubber screw
extruder with pushing package. All technical specifications of
product design refer to JB/T8853-2001 "Cylindrical gear
reducer". The main character of ZLYJ series gearbox is high
strength alloy steel that being used for gear and shaft parts.
The gears are processed by technique of carbonization,
quenching and grinding. The gears' accuracy are GB10095-88, 6
grades. The hardness of tooth surface are HRC54 ~ 62. In
fore-end of hollow shaft the reducer is equipped with
large-sized thrust bearings to bear the axial thrust when screw
works. The set gear reducer has the advantages of small size,
high load capacity, smooth transmission, low noise and high
efficiency.
II. The Scope of Application:
1. The rotary speed of high-speed shaft is no more than 1500 r
/ min.
2. The circumferential velocity of transmission gears is no
greater than 20 m / sec.
3. The working ambient temperature is -40° C ~ 45° C, if less
than 0° C, the oil lubrication should be heated above 0 degree
before starting.
4. The reducer can be used to run both positive and negative
direction, but high-speed shaft of some models is equipped with
one-way oil pump, so its default direction: When face output
shaft, the output shaft clockwise rotate. If the rotary
direction is changed, please state when ordering.
