Problems solved by technology

However, when the intermediate roller is skewed, the contact between it and the driving and driven wheels will cause relative speed and sliding wear in the lateral direction due to the inconsistency of the contact point speed direction, which will affect the transmission efficiency.
Therefore, this speed change method is not suitable for taking a larger friction coefficient, and its bearing capacity must be very low.

Abstract

The invention discloses a steering reducing infinitely variable speed mechanism with double intermediate rollers. The mechanism comprises an input shaft, an intermediate shaft, a master pin, a first intermediate roller, a second intermediate roller and an output shaft, and a pair of intermediate rollers with viscoelastic behavior is adopted as the first intermediate roller and the second intermediate roller. The intermediate rollers are enabled to deviate laterally to change radial positions thereof under the action of lateral force so as to regulate the speed ratio. The mechanism has the advantages that contact radius of a high-friction-coefficient driving wheel is controlled to be changed smoothly and continuously under the conditions of low resistance and low wear, the structure is simple, infinitely variable speed control is simplified, and bearing capacity of a frictional infinitely variable transmission is improved.

Description

technical field [0001] The invention belongs to the field of mechanical transmission, and in particular relates to a friction-type continuously variable transmission device with a double-middle roller steering diameter-reducing mechanism. Background technique [0002] The mechanical continuously variable transmission mechanism is a mechanical transmission device with continuously adjustable transmission ratio, which is widely used in various mechanical equipment and has various types of mechanisms. Such as moving roller flat disc type, cone disc ring disc type, optical axis swash plate type, roller flat disc type, arc cone ring disc type, etc. Friction transmission is a common mechanism type of mechanical continuously variable transmission, such as the common metal belt continuously variable transmission (VDT-CVT). The friction transmission mechanism uses the friction force between the transmission parts to transmit motion and power under the action of a certain positive pr...
