Problems solved by technology

The disadvantages of these non-mechanical micro-drive technologies are complex structure, high price, and unstable performance.
And the most important feature of non-traditional mechanical micro-drive technology is that it is only suitable for instantaneous triggering or intermittent transmission of small displacement or small force, and cannot guarantee continuous and stable transmission.

Embodiment Construction

[0019] The method and mechanism of the invention are suitable for providing drivers for micro-mechanical devices. like figure 1 As shown, the space curve meshing transmission mechanism is composed of a driven wheel 1, a driven wheel hook bar 2, a driving wheel hook bar 3, a driving wheel 4, and a micro-motor 5. The driving wheel 4 is connected with the main shaft of the micro-motor 5, and the driven wheel 1 is connected with the rotating shaft of the driven device. The transmission pair is formed between the driving wheel 4 and the driven wheel 1 by the driving wheel hook bar 3 and the driven wheel hook bar 2 .

[0020] The transmission principle of the space curve meshing transmission mechanism is: the driving wheel rotates under the drive of the micro-motor, and a pair of driving wheel hook rods contact with the driven wheel hook rods to start meshing. At this time, the driven wheel hook rods hinder the driving wheel hook rods Motion, the interaction between them produces ...

Abstract

The invention discloses a space curve engagement and transmission mechanism, which is a novel transmission mechanism on the bases of the engagement principle of space curves. The transmission mechanism comprises a driving wheel, a driven wheel, a plurality of driving wheel hook levers and a plurality of driven wheel hook levers, wherein, the driving wheel hook levers are uniformly arranged on the end surface of the driving wheel; the driven wheel hook levers are uniformly arranged on the circumference of the driven wheel in a single row; the driving wheel hook levers and the driven wheel hook levers are in a conjugated spatial engaging curved shape; the driving wheel and the driven wheel which have mutually vertical axes form a transmission pair; and when the driving wheel is rotated, continuous stable engagement transmission is generated between the driving wheel hook levers and the driven wheel hook levers. The transmission mechanism has the advantages as follows: the mechanism is provided with only one transmission pair so that the number of transmission unit parts is minimized and the structure of the transmission unit is quite simple; transmission with high transmission ratio, such as the transmission of worm and gear, is achieved; and since two wheel axles are positioned on the same plane, the space dimension is smaller and the process is easy.

Description

technical field [0001] The invention relates to micro-electromechanical system transmission technology, in particular to a space curve meshing transmission mechanism. Background technique [0002] With the improvement of the level of science and technology and social living standards, the miniaturization of electromechanical products has become one of the trends. Micro-Electro-Mechanical Systems (MEMS) has become a hotspot in the field of mechanical research. The micro / micro transmission mechanism or reducer is the key component of MEMS products, so the research and development of micro mechanical transmission technology has become one of the research hotspots in mechanical science. Since the most important features of micro / miniature electromechanical products are small size (requiring the transmission mechanism and transmission system to occupy a small space) and light weight, most of them focus on small-power motion transmission or indexing motion, rather than high-power...
