Abstract

The invention discloses a multipurpose screw and idler wheel coupling drive device, belonging to mechanical drive devices. A conventional coupling drive device has the disadvantages of stress concentration, fatigue fractures, surface abrasion or limited linear displacement distance in the process of converting the rotational movement to linear movement or movement in a big curve. The multipurpose screw and idler wheel coupling drive device comprises a track, a pulley, a screw, a driving device and idler wheels. The pulley slides along the track and is connected with a load to output kinetic energy. The screw is axially positioned on the pulley and can rotate along the axis of the pulley, and the screw extends in the same direction with the track. The driving device is arranged on the pulley to drive the screw to rotate around the axis of the pulley. The idler wheels are lined on the track in the extension direction of the screw and the idler wheel corresponding to the screw is located inside a spiral groove of the screw. The multipurpose screw and idler wheel coupling drive device can change the rotation direction of the screw by converting the coupling of the screw and the idler wheels to linear or approximately linear movement, and in such a way, the motion direction of the pulley can be changed and the transmission efficiency is high. The screw can be coupled with a plurality of idler wheels at the same time, so stress concentration can be avoided and the reliability and the safety are improved.

Description

technical field [0001] The invention belongs to a mechanical transmission device, in particular to a multipurpose screw and roller coupling transmission device. Background technique [0002] In the field of mechanical transmission, to convert the rotary motion of the machine into long-distance linear or near-linear motion, the existing technology is mainly realized by rack and pinion transmission. If the stroke is not very long, it can also be realized by screw and nut transmission. . However, when the rack and pinion rotate, under the condition of heavy load, because the contact between the gear and the rack is sliding friction, and the degree of coincidence is very low, it is easy to cause stress concentration, fatigue fracture and surface wear to cause failure; In this way, due to the limitation of the length of the screw rod, the distance of linear movement is limited, and it can only move in a straight line. Contents of the invention [0003] The technical problem t...
