A driven sprocket system for multi-phase transmission

Abstract

The invention discloses a driven chain wheel system for multiphase transmission, wherein a first-phase chain wheel and a first-phase one-way clutch of the driven chain wheel system form a first-phase transmission system; a second-phase chain wheel and a second-phase one-way clutch of the driven chain wheel system form a second-phase transmission system; protruding columns of the second-phase chain wheel and grooves of the first-phase chain wheel fit to elastic components mutually; and the first-phase transmission system and the second-phase transmission system are elastically connected, so that a multiphase transmission system is formed. Transmission directions of the first-phase one-way clutch and the second-phase one-way clutch are the same; and when the elastic components are not deformed elastically, the symmetrical centerline of each protruding column overlaps with the symmetrical centerline of each groove. By means of the unidirectional transmission characteristic of force and speed of the one-way clutch, undesirable torque located on a driven chain wheel and a shaft is eliminated, and transmission noise of the system is reduced; and an elastic connection mode is adopted among one-phase chain wheels, so that the speed fluctuation range of an output shaft is reduced, and the speed output of the multiphase transmission is more stable.

Description

technical field [0001] The invention belongs to the technical field of mechanical transmission, and in particular relates to a driven sprocket system for multi-phase transmission. Background technique [0002] The chain is a basic part widely used in the field of mechanical transmission, especially in the conditions of large center distance, severe working conditions and high-speed and heavy-duty working conditions, its transmission performance is better than that of belt transmission and gear transmission, so it has become an important part of construction machinery. One of the preferred forms of many industries such as automobile industry, shipbuilding industry, etc. [0003] Chain transmission can be divided into single-phase transmission and multi-phase transmission according to the number of sprocket phases. The so-called multi-phase transmission refers to the meshing system composed of n hanging chains and multi-phase sprockets with n phases. Generally speaking, the ...

Problems solved by technology

For the manufacturing process, this type of sprocket requires high manufacturing precision, and because the high-precision sprocket cannot completely eliminate the phase angle error between the driving sprocket and the driven sprocket, resulting in various The transmission error between phases cannot be eliminated, so this sprocket form not only greatly increases the labor cost, but also the transmission effect is not ideal; for the driven sprocket, due to the polygon effect, each phase at the same time The relative speeds of the sprockets must be different, so the phase angles between the single-phase driven sprockets have a relative change trend. If these systems with relative change trends are fixedly connected in a large system, multiple sets of Undesirable torques with different directions and magnitudes are applied to the multi-phase driven sprocket and shaft, which makes the multi-phase transmission sprocket and shaft more likely to be damaged

[0006] The existing Chinese patent (publication number: CN 204533395U) relates to a multi-phase transmission toothed chain transmission system, but the rigid connection between the phases of the driven sprockets described in it does not allow the sprockets of each phase to The self-adjustment of the phase angle will cause the driven sprocket to bear multiple sets of bad torques during the transmission process, which will shorten the life of the driven sprocket and the output shaft, reduce the transmission accuracy of the system, and cause a certain phase of the chain to be sporadically Sexual jumping of teeth increases the impact and noise of transmission
