Performance and advantages of SGR's toroidal worm reducer

In the product family of sgr industries, in addition to the well-known planetary gear reducers, there is also a toroidal worm reducer, which is highly loved and favored by customers because of its high load-bearing capacity, high transmission efficiency and self-locking performance. It is widely used in industrial automation, heavy machinery, wind power generation, marine engineering and other fields.

So, what are the performance and advantages of SGR’s toroidal worm reducer? Let's unlock them together!

(1) Efficient single-stage toroidal worm reducer

The single-stage toroidal worm reducer is a specially designed worm reducer that uses the unique meshing method of the toroidal worm and the worm wheel to achieve power transmission. In the deceleration process of the single-stage toroidal worm reducer, only one set of worm and worm wheel is used instead of multiple sets in series.

Mechanical parameters of SGR’s single-stage toroidal worm reducer:

The characteristics of SGR's single-stage toroidal worm reducer are that the worm and worm wheel are multi-tooth meshing, the worm tooth surface hardness reaches HRC58~62, and the worm wheel is made of high-performance alloy bronze, which can maintain long-term wear resistance, high transmission efficiency, and long life. Compared with the worm wheel pair with cylindrical worm tooth shape of the same specification, the load capacity and service life are increased by 2~4 times, and the transmission efficiency is increased by 2 times. SGR can provide toroidal worm and worm wheel pairs and reducers according to users’ requirements.

Among the single-stage cylindrical worm reducers of SGR Industry, there is also a high-efficiency double-enveloping worm reducer. The high-efficiency double-enveloping worm reducer adopts a universal double-enveloping worm gearbox, which has the characteristics of smooth operation and no noise. It is more efficient than traditional worm gear transmission and has increased load-bearing capacity. SGR Industry can also provide customized designs for various application requirements.

(2)Efficient double -stage toroidal worm gear reducer

The double-stage toroidal worm reducer is a worm reducer that achieves a larger reduction ratio through two-stage transmission. Compared with the single-stage toroidal worm reducer, the double-stage toroidal worm reducer can achieve a higher reduction ratio in a more compact design by connecting two worm and worm wheel assemblies in series (or a complex multi-tooth structure) while maintaining high efficiency and load-bearing capacity.

Mechanical parameters of SGR's double-stage toroidal worm reducer:

The characteristics of SGR's double-stage toroidal worm reducer are multi-tooth meshing between the worm and the worm wheel. The hardness of the worm tooth surface reaches HRC58~62. The worm wheel is made of high-performance alloy bronze, which can maintain long-term wear resistance, high transmission efficiency and long service life. Compared with the worm wheel pair with cylindrical worm teeth of the same specification, the load-bearing capacity and service life are increased by 2~4 times.

（3）Performance advantages of SGR's toroidal worm reducer

SGR Industries has obvious advantages in the research and development, design, production and manufacturing of toroidal worm reducers, which also lays the foundation for the performance advantages of SGR Industries' toroidal worm reducers.

SGR uses the toroidal worm gear design software to implement product design, three-dimensional structure design, strength verification, and based on the meshing principle, SGR has established a tooth surface model to determine the distribution of the contact area, and uses the modification technology to optimize the distribution range of the tooth surface contact line.SGR Industry has won the design patent certificate issued by the State Intellectual Property Office for its innovative design of the plane double enveloping toroidal worm reducer

When manufacturing toroidal worm reducers, SGR Industries got rid of the traditional process of making special cutters, and SGR usually cut the spiral grooves of the worm on a CNC lathe. The gear cutting and fine turning are completed in one clamping, with high processing efficiency and guaranteed precision; The grinding of the worm tooth surface is carried out in a multi-axis linkage mode. This improves processing efficiency and ensures processing accuracy!

It is worth mentioning that the four-linkage toroidal worm CNC turning and grinding compound machine tool independently developed by SGR Industry has won the dual certification of invention patent  and utility model patent issued by the State Intellectual Property Office, which demonstrates SGR's profound R&D foundation and forward-looking vision in the field of efficient toroidal worm gears.

When conducting factory inspection on toroidal worm reducers, SGR Industries uses toroidal worm and hob measuring instruments to test the accuracy of the worm and hob. For key components, SGR Industries will conduct inspection experiments on the three-coordinate measuring center to ensure that each specification of reducer has been run-in at no load and meets the design requirements before leaving the factory!

It is SGR’s multiple advantages in the design, development, manufacturing, testing and delivery of toroidal worm reducers that have created the performance advantages of SGR’s toroidal worm reducers. The outstanding performance of SGR Industry's toroidal worm reducers in terms of load capacity, transmission efficiency, self-locking performance, running stability and noise control will also surely push the brand of SGR Industry to a bigger stage.(Author: SGR, Angie Zhang)
