Product Description

Transmission of csD-20-120-2UF motion for hamenaco Clutch unit harmonic drive. Harmonic drive is usually composed of three basic components, including a rigid wheel with inner teeth, a flexible wheel with outer teeth that can produce radial elastic deformation when working, and a wave generator installed in the flexible wheel internal transmission part wave, oval shape, with flexible rolling bearings in the outer ring. The number of external teeth of flexible wheel is less than the number of internal teeth of rigid wheel. When the wave generator rotates, the outer teeth of the flexible wheel corresponding to the long axis direction just completely engage the inner teeth of the rigid wheel

Because it is a kind of overspeed clutch, it can only engage under the condition that the speed change of the input shaft and output shaft can pass the synchronization point. If the speed change of the input shaft and output shaft cannot pass the synchronization point, the harmonic drive CSD-20-120-2UF of hamanaco clutch unit cannot be used.

It is a single steering clutch, that is, when the structure of the clutch is determined, it can only operate with a fixed steering and never allow reverse engagement. Transmission efficiency The efficiency of gear drive will affect the selection of motor power, and the excessive friction torque of harmonic drive CSD-20-120-2UF of Hamenaco clutch unit will reduce the smooth speed range of the servo system, and even cause low-speed crawling phenomenon.

The efficiency requirements of small module gear drive, although not as important as the power gear drive, but, after all, the power of the motor of the small power drive system is limited hamenako clutch unit harmonic drive CSD-20-120-2uF (generally is a fraction to dozens of KW, two sometimes the efficiency problem is also very prominent.

Precision machinery and instruments commonly used gear transmission type for cylindrical gear (straight tooth and helical tooth) transmission, helical gear transmission, bevel gear transmission, rack transmission and worm gear transmission. In the manufacture of precision machinery and instruments, straight cylindrical gears are more used. Hamenako clutch unit harmonic drive CSD-20-120-2UF is because the design and manufacture of straight cylindrical gears are more convenient, and its transmission accuracy and efficiency are also higher.

The clearance system of gb standard based on circumferential clearance is different from that of gb standard. In the machine standard, the clearance of tooth side is based on the original tooth shape displacement, and the harmonic transmission csD-20-120-2UF of Hamenako clutch unit can be derived from other indicators. The national standard is based on the gear backlash (i.e. the so-called single gear backlash).
