Small worm, great achievement! A clear explanation of the planar secondary enveloping worm gear reducer
When it comes to reducers, people will think of planetary gear reducers. In the reducer family, if planetary gear reducers are shining star products, then planar secondary enveloping worm reducers are an unknown dark horse product. As early as the late 16th to early 17th century, planetary gear systems began to appear in some precision instruments, such as astronomical clocks. The history of planar double enveloping worm gear reducers is not as long as that of planetary gear reducers, but they have also played an irreplaceable role in the field of mechanical transmission.

Unique structure, achieving efficient transmission

The planar secondary enveloping worm gear reducer is mainly composed of a worm, a worm wheel, and bearings. Worm gear has a special spiral surface shape, and the tooth surface is finely ground after nitriding, with high precision, smooth surface, and matching with the worm gear tooth shape, forming multi-point contact; Worm gears are made of high-quality bronze or other wear-resistant materials to ensure good wear resistance and fatigue resistance under high load conditions; Bearings are used to support the rotational motion of worms and worm gears, ensuring smooth operation and low noise.

Outstanding advantages and wide application fields

The contact between the planar secondary enveloping worm gear and the worm wheel is multi-point contact. This design reduces the pressure at each contact point, significantly improving the load-bearing capacity and making the reducer operate more smoothly, reducing vibration and noise; It is precisely because of the unique design of the worm gear and worm that when the worm gear is subjected to external forces, it is difficult to drive the worm in the opposite direction, thus creating its "self-locking performance". The structure of the planar secondary enveloping worm gear reducer is compact, which can provide a large reduction ratio and torque output in a limited space. In addition, the planar secondary enveloping worm gear reducer also has the advantages of long service life and high reliability.

Working principle: Worm gear reducer is a power transmission mechanism that uses the speed converter of gears to reduce the rotation of the motor to the desired rotation and obtain a large torque. The worm is equivalent to a screw, and the worm wheel is equivalent to a nut that meshes with the screw. When the worm rotates, it drives the worm wheel to rotate through the engagement of the threads. Due to the small helix angle of the worm and the large number of teeth of the worm wheel, the purpose of deceleration is achieved, and the output torque is also increased by 14.

Feature 1

Compact mechanical structure: Lightweight in size and shape, compact and efficient, capable of achieving large transmission ratios in a small space.

Good heat exchange performance: fast heat dissipation, can effectively reduce operating temperature, improve equipment stability and service life.

Easy to install: flexible and lightweight, superior performance, easy to maintain and repair, and can be installed in various forms according to actual needs.

Smooth operation: Low noise, durable, with minimal vibration and impact during operation, providing stable power transmission.

Strong usability: High safety and reliability, with self-locking function under certain conditions, that is, only the worm can drive the worm wheel to rotate, and the worm wheel cannot drive the worm to rotate, which can prevent load reversal and improve the safety of the equipment.
