Worm gear reducer is a kind of power transmission mechanism, which uses the speed converter of gear to reduce the rotation number of motor to the required rotation number and obtain a large torque. In the mechanism used to transmit power and motion, the reducer is widely used. Let's understand the working principle of the worm gear reducer !


 Working principle of worm gear reducer:

① The structure of the worm gear reducer box is integral, with beautiful appearance and good rigidity.

② The box type has the basic type (the box body is a vertical or horizontal structure with a baseboard) and the universal type (the box body is a cuboid, with fixed screw holes on many sides, without a baseboard or with another baseboard and other structural types)

③ There are two connection modes of input shaft: basic type (single input shaft and double input shaft) and with motor flange.

④ The output shaft structure has two types: basic type (single output shaft, double output shaft) and hollow output shaft.

⑤ The position direction of the output and input shaft has the input shaft at the bottom and at the top; The output axis is up and down, and the input axis is up and down.

⑥ Two or three reducers can be used to form a multi-stage reducer to obtain a great transmission ratio. Installation type and output mode: base type, flange type and torsion arm type installation, solid shaft and hollow shaft output and worm direct output.


Function of worm gear reducer

As a traditional transmission device, the worm gear reducer is internally composed of worm gear and worm, and the shape is involute. Worm gear reducer has the following advantages:

① Compact mechanical structure, light volume, small and efficient;

② Good heat exchange performance and fast heat dissipation;

③ Simple installation, flexible and light, superior performance, easy pollution, maintenance and repair;

④ Large transmission speed ratio, large torque and high overload energy;

⑤ Stable operation, low noise and durability;

⑥ Strong applicability, high safety and reliability;

⑦ Long service life, low input speed range and large deceleration range;

⑧ With self-locking function, it is suitable for lifting operation.


Installation of RV worm gear reducer:

1. Various installation forms can be adopted according to the actual requirements, and multiple surfaces can be installed;

2. The installation must be firm and reliable;

3. The working mechanism of prime mover and reducer shall be carefully aligned, and the error shall not be greater than the allowable compensation of the coupling used;

4. Rotate by hand after installation. It must be flexible and free of jamming.


Precautions for RV worm gear reducer:

1. The worm speed of RV worm gear speed machine shall not exceed 1500r / min.

2. The working ambient temperature is - 40 ° C - + 40C. When the working ambient temperature is lower than 0C, the lubricating oil must be heated to more than 0 ° C before starting. When the working ambient temperature is higher than 40 ° C, cooling measures must be taken.

3. The input shaft of worm gear reducer can rotate forward and backward.



The above is a brief introduction to the working principle and function of worm gear reducer. I hope it will be helpful to you. It also manufactures precision worm gears, double lead worm gears, worm gear reducers and worm reducers for transmission precision industry. The enterprise has nearly 100 production and processing equipment, such as full CNC worm grinder, CNC cylindrical grinder, CNC gear hobbing machine, CNC lathe and so on.
