Stepless Industrial Reduction Gearbox Automatic High Speed Reduction Gearbox

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.
