Problems solved by technology

[0006] When the ball screw pair is displaced through the stroke, the loss caused by linear friction is large, and the accuracy cannot be guaranteed. Therefore, the disadvantages of the ball screw transmission pair are: serious wear in the transmission control, low accuracy retention, and insufficient speed. , high cost; especially when carrying out large strokes, these defects of the ball screw pair are more serious, and people are constantly looking for new mechanisms to improve the existing ball screw pair mechanism

Abstract

The invention discloses a transmission mechanism, which comprises a driving device and a transmission device, wherein the driving device is used for driving the transmission device. The transmission device comprises a multi-groove spiral line roller, a steel wire, a steel wire transmission mechanism and a steel wire conveying mechanism, wherein the steel wire is connected with an actuator, the steel wire transmission mechanism transmits the steel wire to be wound on the multi-groove spiral line roller, and the steel wire conveying mechanism draws the steel wire to the actuator. The transmission mechanism based on pure rolling friction is capable of realizing the function of large-lead, large-travel and high-speed movement, and a steel wire spiral line transmission pair is simple and reliable in structure, low in wear, gapless in transmission and quite high in precision.

Description

technical field [0001] The invention relates to the field of mechanical transmission, in particular to a transmission mechanism. Background technique [0002] The ball screw pair is often used in the mechanical field. As a transmission mechanism, it is composed of a motor, a ball screw, a ball nut (component) and a ball. It can change rotary motion into linear motion, or linear motion into rotary motion. , The ball screw pair is a product with a wide range of applications and a high degree of specialization. [0003] The ball screw pair is a screw transmission element with balls as rolling bodies between the screw and the nut. There are various structural types of ball screw pairs. According to the ball circulation method, it is divided into two categories: outer circulation and inner circulation. The outer circulation bead return device is mostly of the intubation type, and the inner circulation bead return device is mostly of the waist-shaped groove insert type. [000...
