Planetary Gearbox Manufacturers

Planetary Gearbox Manufacturer and Custom Gear Reducer Factory

Shanghai SGR Heavy Industry Machinery Co., Ltd. is a high-tech enterprise specializing in gear transmission. As a Planetary Gearbox manufacturer and custom gear reducer factory, we design and produce compact, modular, and standardized planetary reducers that deliver high torque density, low vibration, and low noise for demanding industrial applications.

Our planetary gearbox range covers two main configurations: Coaxial Planetary Gear Reducer and Right Angle Planetary Gear Reducer. Each is engineered for specific mounting and shaft layout requirements, ensuring optimal integration into your machinery.

Our Planetary Gearbox Range

Engineering and Customization

We understand that every application has unique demands. Our engineering team works with you to configure the right planetary gearbox based on your specific torque, speed, and mounting requirements. We offer:

• Ratio range from 3.15 to 9000, covering a wide spectrum of speed reduction needs.
• Input power up to 55 kW, with permissible output torque up to 800,000 N·m.
• Low-speed shaft options: solid with key, splined, hollow with shrink disc, or splined hollow shaft.
• Housing materials: rigid nodular cast iron for durability and vibration damping.
• Gear materials: high-quality 20CrMnTi alloy steel, carburized, quenched, and precision ground for long service life.

For example, our N series coaxial reducers are used in agricultural machinery in Argentina, where they withstand heavy dust, vibration, and temperature variations. The fully sealed housing protects internal components, and precision-ground gears with optimized tooth profiles reduce noise and stress.

Quality Assurance and Testing

As a factory, we maintain strict quality control throughout production. Our in-house laboratory is equipped with advanced testing instruments, including a coordinate measuring machine and a gearbox power performance test platform. Each unit undergoes full inspection according to customer requirements, ensuring reliable performance and compliance with international standards.

We are ISO 9001 certified and have TUV CE approval for EMC and safety standards (IEC 61000 and IEC 62477 series). Our quality system ensures traceability from raw materials to final assembly.

Integration and Support

We provide comprehensive technical support to ensure smooth integration of our planetary gearboxes into your equipment. Our services include:

• Assistance with motor selection and coupling design.
• Guidance on installation, alignment, and lubrication.
• Documentation including dimensional drawings, CAD models, and maintenance manuals.
• After-sales support with a 1-year warranty and spare parts availability.

Information We Use to Configure Your Solution

To prepare an accurate proposal, we need the following details about your application:

• Required output torque and speed.
• Input speed and motor type (electric, hydraulic, etc.).
• Duty cycle and operating environment (temperature, dust, humidity).
• Mounting orientation and space constraints.
• Shaft connection requirements (keyed, splined, hollow).
• Any applicable standards or certifications.

With this information, we can recommend the most suitable planetary gearbox configuration and provide a detailed quotation.

Frequently Asked Questions

What is the difference between coaxial and right angle planetary gearboxes?

Coaxial units have input and output shafts aligned on the same axis, offering a compact inline solution. Right angle units incorporate a bevel gear stage to change the direction of power flow by 90°, which is useful when space is constrained or when the drive needs to turn a corner.

Can you customize the output shaft or mounting arrangement?

Yes, we offer multiple shaft options (solid, hollow, splined) and mounting configurations (foot, flange, shaft). We can also design custom flanges or adapters to match your existing equipment.

What is the typical lead time for a custom planetary gearbox?

Lead time depends on the complexity and quantity. For standard configurations, we can often ship within a few weeks. Custom designs may require additional engineering and production time. We provide a confirmed schedule with each quotation.

How do you ensure the gearbox meets our performance requirements?

We use your specified torque, speed, and duty cycle to select the appropriate gearbox size and ratio. Our engineering team performs calculations and, if needed, can conduct prototype testing. Final units are tested on our power performance platform before shipment.

Do you provide installation and maintenance documentation?

Yes, each gearbox is supplied with a user manual covering installation, lubrication, and maintenance procedures. We also offer remote technical support to assist with any issues.
