Description

Novel line transmission mechanism

Technical Field

The utility model relates to a mechanical transmission field especially relates to a novel line drive mechanism.

Background

Mechanical transmission has many modes, and the mechanical transmission guarantees normal motion of mechanical energy, so the promotion and development in the field of mechanical transmission plays a significant role in the development of machinery. The line transmission is a novel transmission method, similar to the line transmission, is the rope transmission, the present rope transmission technology has certain application, but is not very popular, the principle of the rope transmission is the mechanical transmission that the rope transmission depends on the friction between the rope tightly wound on the grooved pulley and the grooved pulley to transmit power and motion, although it has the rotating motion and the linear motion between the parallel shafts capable of transmitting wet distance or the shafts at any position, the transmission part has the advantages of simple structure, convenient processing, stable transmission, no noise, no vibration and impact, etc., but has obvious disadvantages: the transmission precision is low, and the transmission device is only suitable for transmitting smaller force and moment. The reason for the low transmission precision is various, for example, when the friction between the rope and the sheave is insufficient, the rope slips on the sheave to cause the low transmission precision, which is a common situation, and there is also a certain situation that, because the space of the sheave groove is limited, the sheave can have the following two situations in the continuous take-up process: firstly, because the diameter of the rope occupies a certain space, the rope of the sheave is easy to be overlapped on the first layer of rope when the line of the sheave reaches the same position in the second circle, and when the rope is continuously collected in the chute, if the rope is overlapped on the previous layer, the rope on the upper layer is unstable, and the rope on the upper layer can fall off under slight interference, so that the transmission is stopped, which is a condition of low transmission precision. Secondly, assuming that the ropes can be uniformly distributed on the sliding groove on the rope pulley, but because the space of the sliding groove is limited, after the rope pulley rotates for a plurality of circles, the superposition of the ropes cannot be avoided, and because the diameter of the sliding groove on the rope pulley is increased due to the winding of the ropes, the phenomenon that the ropes shrink more and more along with the rotation times of the rope pulley occurs, which is also the reason that the precision is low due to the inevitable rope transmission; since the rope transmission is based on static friction to drive the rope, the rope transmission can only be adapted to transmit smaller force and moment, and if the mechanical transmission mode is more popular and diversified, a transmission mode capable of improving the defect is very necessary.
