Embodiment Construction

[0032] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0033] It should be noted that like numerals and letters denote similar items in the following figures, therefore, once an item is defined in one figure, it does not require further definition and explanation in subsequent figures. Meanwhile, in the description of the present application, the terms "first", "second" and the like are only used to distinguish descriptions, and cannot be understood as indicating or implying relative importance.

[0034] The preload adjustment in belt drive is very important to the use of belt drive. The preload and the surface roughness of the drive belt directly affect the transmission effect, transmission efficiency and service life of the belt drive. According to different usage environments and usage conditions, the preload should be appropriate. If it is too loose...

Abstract

The embodiment of the invention provides a transmission mechanism and a transmission system, and relates to the technical field of transmission. The transmission mechanism comprises a substrate; a mounting base which is rotatably arranged and is fixed on the base plate after rotating to a preset position; a first transmission wheel which is eccentrically arranged on the mounting base so as to eccentrically rotate when the mounting base rotates; a second transmission wheel which is opposite to the first transmission wheel; and a transmission belt which bypasses the first transmission wheel and the second transmission wheel and is tensioned under the eccentric rotation of the first transmission wheel. The purpose of adjusting the pre-tightening force is achieved by driving the first transmission wheel to eccentrically rotate through rotation of the mounting base, and the adjusting process is easy and convenient to operate. The relation between the magnitude of the pre-tightening force and the rotating angle of the mounting base is a continuous positive correlation curve within a certain range, the magnitude of the pre-tightening force can be conveniently adjusted by adjusting the rotating angle of the mounting base, the transmission efficiency can be guaranteed, and the service life can be prolonged.

Description

technical field [0001] The present application relates to the technical field of transmission, in particular, to a transmission mechanism and a transmission system. Background technique [0002] Belt drive is a kind of mechanical transmission that utilizes a flexible belt tensioned on a pulley for motion or power transmission. The belt transmission has the characteristics of simple structure, stable transmission, shock absorption, large inter-axis distance and multi-axis transmission, low cost, no lubrication, easy maintenance, etc., and is widely used in modern mechanical transmission. [0003] In belt transmission, in order to ensure the friction between the belt and the pulley, the belt needs to be tensioned. In the prior art, tensioning pulleys are generally arranged on the inside or outside of the transmission belt, and the transmission belt is compressed by the tensioning pulleys. The position of the tensioning wheel is not easy to adjust, and the tension force and p...
