Best price ZJW stepless speed reducer chain grate stoker boiler automatic smart coal boilers chain grate boiler
Characteristics
1. ZJW series boiler grate governor adopts multi-stage involute
cylindrical gear deceleration transmission mode, featuring safe and
reliable operation, high transmission efficiency, stable operation,
low noise, long service life, simple and convenient use and
maintenance.
2. The main parts of ZJW series boiler grate governor are designed
with computer-aided optimization design technology, and applied
with various heat treatment processes, carefully manufactured, with
excellent performance and quality.
3. The speed regulating motor is generally equipped with an
electromagnetic speed regulating motor (also called a slip motor),
and can also be equipped with an AC variable frequency motor
according to user requirements. According to the different
operating conditions of the boiler, by adjusting the speed control
knob of the motor controller, the motor speed can be changed, so
that the running speed of the grate can be adjusted steplessly
within a certain range, so that the coal combustion is fully
burned. The motor controller can be equipped with a computer
interface according to user needs, and can be connected with a
computer for automatic control.
4. The shear-type safety clutch is used as the overload protection
device of the governor. It can effectively cut off the power
transmission when the grate fails and the load torque exceeds the
safe value of the allowable output torque of the governor, thus
effectively protecting the grate and the governor. When the fault
is removed, the security pin can be replaced conveniently and
quickly.
5. Adopt new sealing materials. For the static seal point leakage
of the reducer, a new polymer repair material can be used for
blocking. If the static seal point leaks during the operation of
the reducer, the surface engineered oil surface emergency repair
agent sticky-polymer 25551 and 90T composite repair materials can
be used to block the oil leakage.
6. The company optimizes the gear parameters such as the
displacement coefficient, the tooth height coefficient, the
pressure angle and the center distance to minimize the impact
velocity and effectively reduce the running noise of the equipment.
7. Design a new oil cup type venting cap, weld the oil cup type
venting cap on the cover plate, the venting hole diameter is 6 mm,
which is convenient for ventilation, realizes the pressure
equalization, and refuels from the oil cup when refueling, without
opening the inspection The hole cover plate reduces the oil leakage
problem during the operation of the reducer.
Installation Precautions
1. The connection between the reducer and the working machine: the
reducer is directly set on the working machine spindle. When the
reducer is running, the counter torque acting on the reduction gear
body is mounted on the counter-torque bracket of the reduction gear
body or by other Method to balance. The machine is directly
matched, and the other end is coupled with the fixed bracket.
2. Installation of the anti-torque bracket: The anti-torque bracket
should be installed on the side of the working machine facing the
reducer to reduce the bending moment attached to the working
machine shaft. The sleeve of the anti-torque bracket and the fixed
support coupling end uses an elastic body such as rubber to prevent
deflection and absorb the generated torque fluctuation.
3. Installation relationship between the reducer and the working
machine: In order to avoid the deflection of the working machine
main shaft and the additional force on the reducer bearing, the
distance between the reducer and the working machine should be as
small as possible without affecting the normal working conditions.
, its value is 5-10mm.
Features of different types of reducer
The main feature of the worm gear reducer is that it has a reverse self-locking function and can have a large reduction ratio. The input shaft and the output shaft are not on the same axis, nor on the same plane. The planetary reducer has the advantages of compact structure, small return clearance, high precision, long service life and large rated output torque. The gear reducer has the characteristics of small size and large transmission torque. The gear reducer is designed and manufactured on the basis of the modular combination system. There are many motor combinations, installation forms and structural schemes. The transmission ratio is finely graded to meet different working conditions and realize electro-mechanical integration. The gear reducer has high transmission efficiency, low energy consumption and superior performance. The cycloidal pinwheel reducer is a transmission type that adopts the principle of cycloidal pin gear meshing planetary transmission. It is an ideal transmission device with many advantages, wide application and forward and reverse operation.
