K Series Bevel Gear Motors
Description
The K series gear motor is a spiral bevel gear (or bevel gear) reducer, renowned for its right-angle output design. It features an integrated motor and reducer design, utilizing a combination of helical and spiral bevel gears for power transmission. It is particularly suitable for industrial equipment requiring variable direction of motion.
Technical Features
The K series gear motors are popular across numerous industrial sectors due to their multiple advantages in design, materials, and performance.
High Transmission Efficiency: Utilizing hardened gears and an optimized transmission structure, the K series achieves an average transmission efficiency exceeding 94%, with some models exceeding 95%, helping to reduce operating energy consumption.
Compact Structure and Right-Angle Output: Using spiral bevel gears for right-angle transmission, this design effectively saves installation space and is particularly suitable for compact equipment.
High Torque and Strong Load-bearing Capacity: Gears are made of high-quality alloy steel (such as 20CrMnTi) and undergo heat treatment processes such as carburizing and quenching. The gear surfaces are highly hard (up to HRC58-62) and wear-resistant, capable of withstanding heavy radial and axial loads. Output torque reaches up to 50,000 Nm.
Modular Design: The modular design offers excellent adaptability and allows for flexible integration with various motor types (such as three-phase asynchronous motors, variable-frequency motors, and servo motors). It supports a variety of mounting methods, significantly reducing component variety and inventory requirements.
Smooth Operation and Long Life: Gears are precision-ground (to a precision of 5-6) for smooth transmission. Combined with a rigid cast iron housing (some smaller sizes are aluminum) and a well-sealed structure, the product offers low vibration, low noise, minimal maintenance, and a long service life.
