What exactly is the product of the harmonic reducer manufacturer

2020-04-03

The product of harmonic reducer manufacturer is a kind of fixed inner tooth rigid wheel, flexible wheel and wave generator that makes the flexible wheel deform radially. Harmonic gear reducer is a new type of transmission structure in gear reducer. It uses flexible gear to generate controllable elastic deformation wave, which causes the relative wrong teeth between rigid wheel and flexible wheel to transmit power and motion. This kind of transmission is essentially different from the general gear transmission, and has particularity in meshing theory, set calculation and structural design. Harmonic gear reducer has the advantages of high precision and high bearing capacity. Compared with ordinary reducer, its volume and weight are reduced by at least 1/3 due to the use of 50% less materials.

The transmission method of the products of the wave reducer manufacturer is the same as the planetary gear transmission. The harmonic gear transmission is also composed of three basic components: a fixed internal tooth rigid wheel, a flexible wheel and a wave generator that causes radial deformation of the flexible wheel. Cut teeth with the same modulus on 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 two less than the number of teeth of the rigid wheel. The tooth number difference of the harmonic drive characterizes the deformation wavenumber of the flexspline. The most common is the wave number w-2 harmonic drive. In the free state, the two wheels are in a concentric position, while the gap between the teeth of the rigid wheel and the flexible wheel is uniform. The generator installed in the flexspline causes the flexspline to deform radially into an oval shape. At this time, on the major axis of the ellipse, the teeth mesh along the entire working height, while on the minor axis, a radial gap is formed between the tooth tips. During rotation of the generator, the shape of the flexspline is always close to that described above. The composition structure of the products of harmonic reducer manufacturers Harmonic gear reducer is composed of three main components: rigid wheel, flexible wheel and wave generator. Among them, the wave generator is the driving part, and one of the rigid wheel and the flexible wheel is the driven part.

The fixed rigid wheel is a rigid internal gear, and the flexible wheel is a thin-walled cylindrical external gear that is easy to deform. They have triangular (or involute) tooth shapes together, and the circumference of the two is equal, but the rigid wheel has more teeth than the flexible wheel. The wave generator consists of an elliptical disc and a flexible ball bearing, or a rotating arm with rollers at both ends. Usually the wave generator is the original moving body, one of the flexible wheel and the rigid wheel is the driven body, and the other is the fixed part.
