Fixed tooth stepless speed change method and device

Abstract

According to the fixed-tooth stepless speed change method and device, when input exists, a hollow gear is meshed with a fixed gear to form revolution of a gear shaft, an eccentric circle holder forms eccentric rotation due to the action of an eccentric circle on the gear shaft, and at the moment, if a speed change holder does not generate an inclination angle, the speed change holder does not generate an inclination angle; when the variable-speed retainer generates an inclination angle, one part of the gear shaft moves downwards in the rotating process, the other part of the gear shaft moves upwards, and the generated effect is that one part of the eccentric circle rotates in an accelerated mode relative to the gear shaft; the other part of the eccentric circle rotates in a speed reduction mode relative to the gear shaft, at the moment, the eccentric circle holder can generate the effect of superposition of eccentric rotation and eccentric revolution, the eccentric revolution can enable the output eccentric circle to generate output, and in the input process, the larger the inclination angle of the speed change holder is, the more the eccentric revolution of the eccentric circle holder is, and the faster the output is; the vertical movement amplitude of the gear shaft is determined by the inclination angle of the speed change retainer, the output amount or speed is determined by the vertical movement amplitude, the forward rotation or the reverse rotation of the output is determined by the initial inclination direction of the speed change retainer, and then stepless speed change starting from zero is achieved.

Description

technical field [0001] The invention belongs to the field of stepless speed change, and relates to a method and device for stepless speed change of fixed teeth. Background technique [0002] Our company has previously applied for "A Method and Device for Mechanical Stepless Transmission", patent number 202110993378.6. By constructing multiple mechanisms on the output shaft that can freely circulate or reciprocate, the mechanism is a synthesis of two cyclic reciprocating structures. When one structure is always doing cyclic or reciprocating motion while the other structure is not doing reciprocating motion, a tangent but non-interfering curved surface is constructed, and the mechanism that pushes the cyclic reciprocating motion structure to run is in the same direction as the curved surface, and the output is to push The mechanism that has been doing circular reciprocating motion and the curved surface produce a superimposed effect. This mechanism and the curved surface alter...

Problems solved by technology

[0003] However, in the transmission system, the contact between the hyperboloid structure and the eccentric circle is a line contact, and it will not be affected when the torque is small, but there may be a problem of insufficient durability when the torque is high, which will affect the service life and increase the maintenance cost.
