Why do I recommend you choose SGR worm gear reducers?

When it comes to reducers, the first thing that comes to mind is the planetary gear reducer. Among the reducers family, if the planetary gear reducer is the shining star product, then the worm gear reducer with double-enveloping helical gears is the underdog product that remains relatively unknown.

As early as the late 16th century to the early 17th century, planetary gear systems began to appear in some precision instruments (such as astronomical clocks). The history of the worm gear reducers is not as long as that of the planetary gear reducers, but they have also played an irreplaceable role in the field of mechanical transmission.

For over a decade,SGR industry has been deeply engaged in the field of mechanical transmission, consistently focusing on the design, research and development, production and sales of industrial transmission gearboxes. The research and design of double-enveloping worm gear reducers is a key development focus of SGR Industry.

In this article, I will take you to have a detailed understanding of the double-enveloping worm gear reducers.

(1)Features:Unique structure, achieving efficient transmission

The double-enveloping worm gear reducer mainly consists of a worm, a worm wheel and bearings. The worm has a special helical surface shape, and its tooth surface is precisely ground after nitriding, featuring high precision and smoothness, and matching the worm wheel's tooth profile to form multi-point contact. The worm wheel is made of high-quality bronze or other wear-resistant materials to ensure good wear resistance and fatigue resistance under high load conditions. The bearings are used to support the rotational motion of the worm and worm wheel, ensuring smooth operation and low noise.

The operating principle of a double-enveloping worm gear reducer is to transmit power through the meshing of a worm and a worm wheel. A motor or other drive source initiates the rotation of the worm, which in turn rotates the worm wheel, completing the power transmission. The transmission efficiency of a double-enveloping worm gear reducer typically exceeds 85%.

(2) Outstanding advantages and wide application fieldsof worm gear reducers

The contact between the double-enveloping worm and the worm wheel is multi-point. This design reduces pressure at each contact point, significantly improving the load-bearing capacity and making the reducer run more smoothly, reducing vibration and noise. The unique design of the worm wheel and worm makes it difficult to reverse drive the worm when the worm wheel is subjected to external forces, thus creating its "self-locking" property.

The double-enveloping worm gear reducer has a compact structure, capable of providing a large reduction ratio and torque output within a limited space. Furthermore, the double-enveloping worm gear reducer offers advantages such as long life and high reliability.

Thanks to these advantages, the double-enveloping worm gear reducers have a wide range of applications, including industrial automation, heavy machinery, wind power generation, marine engineering, stage machinery and other fields.

(3) Why do I recommend you choose SGR’s flat worm gear reducer?

SGR Industry has strong technological innovation capabilities in the design, manufacturing, testing and inspection of the double enveloping worm gear reducers.

In terms of design, SGR Industry uses independently developed toroidal worm gear design software for product design, three-dimensional structural design, and strength verification. Based on the principle of meshing, a tooth surface model is then created to determine the distribution of the contact area. Profiling techniques are then used to optimize the distribution of the tooth surface contact line. The flat double-enveloping toroidal worm gear reducer developed and produced by SGR Industry has been awarded a design patent by the State Intellectual Property Office, demonstrating SGR Industry's core innovation capabilities.

In terms of manufacturing, SGR Industry has moved away from the traditional process of producing dedicated cutters and blades. Instead, it performs worm spiral groove cutting on modern CNC lathes, completing both cutting and finishing in a single clamping operation, resulting in high efficiency and precision. Furthermore,SGR Industry utilizes a multi-axis linkage method for grinding worm tooth surfaces, based on its four-linkage toroidal worm CNC turning and grinding machine tools and four-linkage toroidal worm turning and grinding machine tools, improving processing efficiency and ensuring precision.

In terms of testing, SGR Industry uses a toroidal worm and hob measuring instrument to check the accuracy of the worm and hob. Furthermore, a three-coordinate measuring machine is used to inspect key components in double enveloping worm gear reducers. This ensures that each specification of reducer undergoes a no-load run-in and meets design requirements before shipment.(Author, SGR , Angie Zhang)
