OPERATION & MAINTENANCE MANUAL STE35SR
Engine
Engine is 3 cylinders, 4 stroke, water-cooling, Models
available as Yuma 3TNV80F or Kubota D1105.
Main Pump
Hydraulic pump is a hydraulic component which converts
mechanical energy into liquid pressure energy. It consists of a
variable ram pump. Constant power plus load sensitive control
mode is adopted.
Main Valve
The main valve consists of 11 valve plates. 11 valves including
first coupling valve, auxiliary valve, stick valve, boom valve,
bucket valve, boom swing valve, rotary valve, left travel valve,
right travel valve, bulldozing the shovel valve is connected to
the end of the valve. (Please refer to the actual product for the
specific order).
Swing Motor and Reducer
Rotary motor and reducer comprises two parts: rotary motor
and reducer. The rotary motor is swash plate axil piston motor,
including a plunger, swash plate, relief valve, check valve and
delay valve. The reducer is composed of star gear, planet gear,
pinion gear and shell. The high speed and small torque output
by the rotary motor main shaft changes to low speed and large
torque after being decelerated by the reducer.
Travel Motor and Reducer
Travel motor and reducer contains the travel motor and the
gear reducer. The travel motor is a swash plate axial piston
motor that also include plunger, inclined plate, brake valve,
balance valve, flow control valve, etc. The reducer is
composed of the sun gear, the planetary gear, the pinion gear
and the gear housing. The high speed and small torque output
from the main shaft of the walking motor changes into low
speed and large torque after deceleration by the reducer.
Two-speed switching can correspond to different working
conditions.
