Sumitomo Parallel Shaft Gearboxes & Speed Reducers

Parallel shaft gearmotors, also known as parallel shaft gearboxes, feature a design in which the input and output shafts are parallel to each other but offset. This design allows for higher torque capacity and a wider range of gear ratios than concentric gearboxes, making them suitable for applications that require higher torque and speed capabilities.

Parallel shaft gearmotors typically consist of two or more sets of gears, with each set mounted on a separate parallel shaft. The gears in the gearbox transmit power and torque from the input shaft to the output shaft through meshing teeth. The input and output shafts are mounted on opposite ends of the gearbox casing and are supported by bearings.

Parallel shaft gearmotors offer several advantages, including:

• High torque capacity: Parallel shaft gearmotors have a higher torque capacity than concentric gearboxes, making them suitable for high-torque applications.
• Wider gear ratio range: Parallel shaft gearmotors have a wider gear ratio range than concentric gearboxes, making them suitable for a wider range of applications.
• Versatility: Parallel shaft gearmotors can be used in a variety of applications, including conveyors, mixers, and pumps.
• Reliability: Parallel shaft gearmotors are known for their durability and reliability, making them a popular choice in industrial applications.

Parallel shaft gearmotors do have some disadvantages, including:

• Increased noise and vibration: The offset design of parallel shaft gearmotors can result in increased noise and vibration compared to concentric gearboxes.
• Higher maintenance requirements: The more complex design of parallel shaft gearmotors may require more maintenance than concentric gearboxes.
• Larger size: Parallel shaft gearmotors are typically larger and take up more space than concentric gearboxes.
