Helical-bevel gear units (two and three stages)

Helical-bevel gearmotors K..DR..

Key Advantages

Robust and Low-Maintenance Design: The helical-bevel gear units are notably robust due to their high-endurance gearing and superior manufacturing quality of all component parts. This ensures longevity and reduces maintenance needs.

High Efficiency and Power Range: When combined with an AC motor, these gearmotors offer high efficiency and can support a motor power range of up to 200 kW, depending on the energy efficiency class required.

Versatile Combination Options: The K..DR.. series provides diverse combination possibilities:

Wide Range of Gear Unit Ratios: Catering to different speed and torque requirements.
Flexible Installation: Options for foot or flange-mounted designs offer adaptability to various installation contexts.
Motor Variants for Different Energy Efficiency Classes: Ranging from IE1 to IE4, allowing for optimized energy consumption according to your operational needs.
Compact and Powerful: The integration of helical-bevel gear units with AC motors results in a compact yet powerful gearmotor, suitable for applications where space is at a premium but high performance is needed.
