Harmonic Reducer CSF-25-50-2UH

The Harmonic Drive Coaxial Drive Harmonic Reducer CSF-25-50-2UH is mainly composed of four basic components: wave generator, flexible gear, flexible bearing, and rigid gear. The harmonic drive reducer is a gear transmission that relies on the wave generator to assemble a flexible bearing to make the flexible gear produce controllable elastic deformation and mesh with the rigid gear to transmit motion and power. The number of external teeth of the flexible wheel is less than the number of internal teeth of the rigid wheel. When the wave generator rotates, the external teeth of the flexible wheel corresponding to the long axis direction just mesh with the internal teeth of the rigid wheel.

Product Description

According to the number of transmission stages, it can be divided into single-stage and multi-stage reducers; according to the shape of the gear, it can be divided into cylindrical gear reducers, bevel gear reducers and bevel-cylindrical gear reducers; according to the transmission layout, the Harmonic Coaxial Transmission Harmonic Reducer CSF-25-50-2UH can be divided into expansion type, split type and coaxial type reducers.

Main types and characteristics of fixed-axis transmission reducers:

Cylindrical single-stage: widely used. Simple structure, easy to ensure accuracy Harmonic Coaxial Transmission Harmonic Reducer CSF-25-50-2UH. The gear teeth can be made into straight teeth, helical teeth or herringbone teeth. It can be used for low-speed heavy loads and can also be used for high-speed transmission

Cylindrical-expanded This is the simplest and most widely used structure in the two-stage reducer. The position of the gear relative to the bearing is asymmetric. When the shaft is bent and torsionally deformed, the load is unevenly distributed on the tooth width Harmonic Coaxial Transmission Harmonic Reducer CSF-25-50-2UH. Therefore, the shaft should be designed to have greater rigidity, and the high-speed shaft gear should be away from the input port. Most hardened gears adopt this structure.

Split type: The high-speed stage is a symmetrical left-right helical gear. The low-speed stage can be a herringbone gear or a straight gear. The gears and bearings are arranged symmetrically. The load is evenly distributed along the tooth width, the bearing is evenly loaded, and the torque on the dangerous section of the intermediate shaft is equivalent to half of the torque transmitted by the shaft. However, this structure will inevitably produce axial movement, which affects the uniformity of the tooth surface load. The structure should ensure the possibility of axial movement. Usually, the large gear of the low-speed stage is axially positioned, and the intermediate shaft gear and the high-speed pinion can move axially

Cylindrical-coaxial line type: The length of the box is reduced. The input shaft and the output shaft are arranged on the same axis, making the equipment layout more convenient
