CF-GH Series Harmonic Drive (Strain Wave Gear Reducer)

CF-GH Series Harmonic Drive (Strain Wave Gear Reducer)

The CF-GH series harmonic drive reducer is an advanced precision gearbox widely used in various industries for high-precision motion control applications. Harmonic drive technology, also known as strain wave gearing, is a compact and efficient gear mechanism that offers superior torque transmission capabilities with zero backlash. The CF-GH series builds upon this technology, incorporating several design enhancements and improvements to deliver even better performance.One of the key features of the CF-GH series harmonic drive reducer is its high torque density. It can transmit a large amount of torque relative to its compact size, making it ideal for applications where space is limited. This high torque density allows for more flexibility in system design and integration. The CF-GH series also offers excellent positional accuracy. It provides precise motion control thanks to its minimal backlash and high torsional stiffness. This accuracy is crucial in applications that require precise positioning, such as robotics, machine tools, and automation systems.Furthermore, the CF-GH series harmonic drive reducer offers a long service life with low maintenance requirements. Its rugged construction and high-quality materials ensure durability and reliability even in demanding environments. This reduces downtime and increases productivity, making it a cost-effective solution for many industries. The CF-GH series harmonic drive reducer is available in various sizes and configurations to accommodate different torque and speed requirements. It can be customized to meet specific application needs, including different mounting options, input and output shaft configurations, and gear ratios.

Components of a Harmonic Drive:

Harmonic transmission device is mainly composed of three basic parts, namely wave generator, flexible wheel and rigid wheel.1. Wave generator: composed of a flexible bearing and an elliptical cam, the wave generator is usually installed at the input end of the speed reducer, the inner ring of the flexible bearing is fixed on the cam, and the outer ring realizes the elastic transformation into an elliptical shape by means of a ball.2. Flexible wheel: a flexible thin-walled elastomer part with a circle of outer teeth, usually installed at the output of the gearhead.3. Rigid wheel: a rigid circular part with a circle of inner teeth, generally 2 teeth more than the flexible wheel, usually fixed on the reducer body.

CF-GH Series Harmonic Drive Reducer Features:

*1 The output torque is set at a value of L10 = 7,000 hours of service life at an input speed of 2,000 r/min for an ordinary same-service motor. Use this as an approximate standard for normal operation.*2 The output torque is set at the value of L10 = 7000 hours of service life when the input speed is kept at 3000r/min for an ordinary homogenous motor. Use this as an approximate standard for normal operation.*3 Maximum allowable average load torque calculated from the load torque mode. Note that exceeding this value may reduce the service life and durability of the product.*4 Maximum allowable torque during start-stop in the operating cycle.*5 Maximum allowable shock torque during an emergency stop and shock torque from external sources. Be sure to use the product within this torque range. In addition, during the model selection process, calculate the allowable frequency and confirm that it meets the operating conditions.*6 Maximum allowable input speed under non-operating conditions. The speed may be affected by the operating environment and operating conditions, but keep the input speed below 3000r/min for continuous operation.*7 Indicates the weight of the gearhead alone. Please refer to the dimension table for values, including input shaft coupling and motor flange.
