The gear reducer in the harmonic reducer is composed of a fixed internal tooth rigid wheel, a flexible wheel, and a wave ultrasonic generator that makes the flexible wheel produce axial deformation. The gear reducer in the harmonic reducer is This new transmission system structure in the reducer uses flexible transmission gears to create steerable and malleable deformation waves, resulting in relative staggered teeth between the teeth of the rigid and flexible wheels to transmit driving force and fitness exercises. This type of transmission system is substantially different from the usual transmission gear transmission, and has diversity in the basic theory of toothing, combined measurement and overall design. Harmonic reducer has the advantages of high precision and high carrying capacity. Compared with general reducers, because the applied raw materials are 50% less, its volume and net weight are reduced by at least 1/3.
The same as the large planetary worm gear drive, the harmonic gear drive system is composed of three basic prefabricated components: a fixed internal tooth rigid wheel, a flexible wheel, (that is, the PCB and the driven shaft are connected with thick ductility). The wall sleeve cup "makes an abs ring on the busway at the beginning of the flexspline") and a wave ultrasonic generator that causes the flexspline to produce axial deformation. Cut out the transmission gears with the same modification coefficient from the rigid wheel and the flexible wheel, but the number of teeth is different, that is, the number of teeth of the flexible wheel is 2 less than that of the rigid wheel. The qualitative analysis of the tooth number difference of the transmission system of the harmonic reducer is the deformation wave number of the flexible wheel. The most common is the pulse current drive system with wave number w-2. Under random conditions (no ultrasonic generator), the two wheels are in the same position, and the tooth gaps of the rigid and flexible wheels are symmetrical. The ultrasonic generator installed in the flexspline causes the flexspline to produce axial deformation and become an ellipse. At this time, on the short axis of the ellipse, the teeth are engaged with the height-to-width ratio at all working edges, while on the short axis, there is an axial gap between the tooth tips. In the whole process of the rotation of the ultrasonic generator, the appearance of the flexspline is close to the stated appearance from beginning to end.
The harmonic reducer is composed of three key prefabricated components: rigid wheel, flexible wheel, and wave ultrasonic generator. Among them, the ultrasonic wave generator is the active part, and one of the rigid wheel and the flexible wheel is the follower. The fixed rigid wheel is a rigid internal transmission gear, and the flexible wheel is a thick-walled drum external transmission gear that is very easy to deform. Together, they have a triangular (or involute gear) tooth profile, and two The perimeter of the wheel is the same, but the rigid wheel has more teeth than the flexible wheel (usually two teeth). The wave ultrasonic generator is composed of an elliptical disk and a soft ball bearing, or a rotating arm containing roller bearings on both sides. Generally, the ultrasonic generator is the driving body, one of the flexible wheel and the rigid wheel is the driven body, and the other is the fixed card.
