Planetary gearbox manufacturer SGR- Shanghai SGR Heavy Industry Machinery Co., Ltd.

Potential mechanical customers often search on Google and social media platforms for "How is the reputation of Shanghai planetary gearbox manufacturer SGR?" They want to know more about the planetary gearbox manufacturer SGR.

As a editor working in SGR for 10 years , in this article, I want to focus on introducing the reputation of the planetary gearbox manufacturer SGR from the perspective of the company , products, facility,and innovative ability.

Product reputation

At SGR, we specialise in manufacturing planetary gearboxes and worm gearboxes for industrial applications in trenchless horizontal directional drilling rig, belt conveyor, sightseeing boat,river dredging boat,cement, rubbe and all types of industries.

SGR's main products are divided into two categories: N-series planetary gearboxes and C-series worm gearboxes.

N-series planetary gearboxes:

The N-series planetary gearboxes utilize 20CrMnTi alloy steel, carburized and quenched, followed by precision grinding, resulting in high transmission efficiency, low noise, and high torque density.

The N-series planetary gearboxes have acquired lots of awards. In 2009,they received the "First Prize for Scientific and Technological Achievements in the Gear Industry" certificated from the China Gear Industry Association in 2009; They were also been recognized as a "Shanghai High-tech Achievement Transformation Project" and have acquired one invention patent.

Core Parameters and Configuration:

Gear ring specifications	200～885mm
Output torque range	T2≤540000N.m
Speed ratio	i ≥3
Design	Modular design, serialized specifications, and specialized production
Input	Input ends include round holes, spline holes, round shafts, internal or external splined shafts, additional flanges, brakes, etc., suitable for hydraulic motors or electromagnetic motors;
Output	Output end types include round shafts, hollow shafts, hollow shafts with tensioning discs, internal or external splined shafts, additional connecting discs, gears, flanges, etc.
Accessories	A variety of accessories are available, including cooling and lubrication devices, backstops, etc., which users can select according to their needs.

C-series worm gearboxes:

The C-series worm gearboxes feature multi-tooth meshing between the worm and worm wheel. The worm is made of 20CrMnTi steel, carburized and quenched, and then ground. The worm wheel is made of high-performance alloy bronze, ensuring long-lasting wear resistance, high transmission efficiency, long service life, and self-locking properties.

Core Parameters and Configuration:

Center distance	100~710mm
Speed ratio	i ≥10
Output torque range	T2≤160000N.m
Design	Modular design, serialized specifications, and specialized production

Customers’ comments:

SGR's gearboxes have been successfully applied in scenarios with extremely high reliability requirements, such as horizontal directional drilling rigs (HDD), tourist boat propulsion systems, hydropower station speed increasers, and port lifting equipment, demonstrating their engineering-proven capabilities under heavy load and continuous operation conditions.

Customers have commented: "SGR's gearboxes offer exceptional value for money, easily replacing imported products. This technology is absolutely top-notch in China."
