Embodiment Construction

[0023] As shown in Figure 1, the main structure of the mechanical twin-screw transmission is a box, on which an input shaft and an output shaft are installed in turn, and bearings are arranged at both ends of the shaft and installed on the bearing seat of the box. The input shaft 1 is provided with two first-stage active screws 3 and 4 with coaxial cores, 3 is a right-handed screw, 4 is a left-handed screw, and the output shaft 2 is equipped with driven screws 5 and 6, which are left-handed driven screws. 6 meshes with the right-handed driving screw 3, and the right-handed driven screw 5 meshes with the left-handed driving screw 4. The transmission ratio of the main and driven screws can be designed as deceleration, constant speed or speed increase. The transmission screws assembled on the same transmission shaft are designed as left and right spiral screws that appear in pairs. The transmission screws can also be designed as Single-start screw or multi-start screw. When the ...

Abstract

The invention discloses a mechanical double-screw driving auxiliary, mainly composed of box body, input shaft, output shaft, master driving screw, slave driving screw and bearing, where the screw driving auxiliary is set in the box body, the input shaft is set with two driving screws; the output shaft is set with two slave driving screws; the mutually-engaged master and slave driving screws rotate oppositely. It both has higher transmission efficiency and can be designed with self-locking function or not according to requirements. Compared with ordinary involute gear driving auxiliary of the same power, it has not only the character of driving efficiency but the advantages of small bulk, light, low noise and stable driving, and also mechanical power amplifying effect. Therefore, it can replace ordinary driving gears and applies to driving systems.

Description

technical field [0001] The invention relates to a mechanical twin-screw transmission pair. Background technique [0002] The standard involute cylindrical gear transmission mechanism widely used at present has no self-locking function despite its high transmission efficiency. However, the transmission efficiency of the worm and gear transmission mechanism with self-locking function is not high, and its use is subject to certain restrictions. The processing technology of the above two devices is complex and the cost is relatively high. Contents of the invention [0003] In order to solve the above problems, the present invention provides a mechanical twin-screw transmission pair with high transmission efficiency, convenient processing and low cost. [0004] The technical solution of the present invention is: it is mainly composed of a box body, an input shaft, an output shaft, a main drive screw, a slave drive screw and bearings, the screw drive is attached to the box bod...
