Problems solved by technology

[0008] In view of the above problems, the present invention provides a mechanism for mutual conversion between reciprocating motion and rotary motion. This mechanism does not need to use a circular slider, thereby solving various problems caused by the existence of a circular slider in the crank circular slider mechanism. At the same time, it can also Continue to retain the various advantages of canceling the connecting rod in the crank circular slider mechanism

Embodiment 1

[0040] figure 1 It is a schematic diagram of the first embodiment of the mechanism for mutual conversion of reciprocating motion and rotary motion of the present invention. figure 2 for figure 1 A schematic diagram of the left view, which is used to illustrate the positional relationship of the reciprocating member of this embodiment, figure 1 Some elements shown in are not shown. image 3 , Figure 4 with Figure 5 Respectively figure 1 The illustrated schematic diagram of the structure of each component in the first embodiment of the mechanism for mutual conversion of reciprocating motion and rotary motion.

[0041] Please refer to figure 1 In this embodiment, the number of the movable shaft pins is three, and each one has a reciprocating member as an example.

[0042] In this embodiment, the mechanism for mutual conversion of reciprocating motion and rotational motion includes a first reciprocating member 14a, a second reciprocating member 14b, and a third reciprocating member 14...

Embodiment 2

[0075] Image 6 It is a schematic diagram of the second embodiment of the mechanism for converting between reciprocating motion and rotating motion of the present invention. In this embodiment, the reciprocating members corresponding to the first crank pin 6a and the third crank pin 6c located at the left and right ends are double-acting pistons, and the reciprocating member corresponding to the second crank pin 6b located in the middle is a dynamic balance slider. The mechanism for mutual conversion of reciprocating motion and rotary motion of this embodiment can also be used to form an H-type four-cylinder internal combustion engine and compressor. The other aspects of this embodiment are the same as the first embodiment described above, and have the same beneficial effects, which are not repeated here.

[0076] In addition; if the reciprocating part on the second moving shaft pin 6b is replaced by a single-acting piston, it can constitute an H-⊥ five-cylinder engine. It can ...

Abstract

The invention relates to a mechanism for mutual conversion between reciprocating motion and rotating motion, which comprises a reciprocating motion part, a rotating motion part and a frame. The rotating motion part comprises two end shafts and a movable shaft. The end shafts can be rotatably fixed on the frame. The rotating shafts of the two end shafts are in one line. A movable shaft neck holding hole is arranged on each end shaft, wherein the distance from the axis of the movable shaft neck holding hole to the rotating shaft is e. Movable shaft necks are arranged at the two ends of the movable shaft. Three movable shaft pins are arranged in the middle, wherein the axis of the three movable shaft pins is in parallel with the axis of the movable shaft and the distance from the axis of thethree movable shaft pins to the axis of the movable shaft is e. Phase difference of 180 degrees is kept for adjacent movable shaft pins in space. When in assembling, the movable shaft necks are respectively and rotatably connected with the movable shaft neck holding holes of the end shafts at the two ends. At least one reciprocating motion part placed in a reciprocating motion track is arranged corresponding to each movable shaft pin and is rotatably connected with the movable shaft pin through a movable shaft pin hole on the reciprocating motion part. Phase difference of 90 degrees is kept for the reciprocating motion tracks of the adjacent reciprocating motion parts in space. Since the mechanism has no connecting rod or circular sliding block, the defect caused by the connecting rod or the circular sliding block to the conversion mechanism is overcome. The invention additionally provides a device using the mechanism.

Description

[0001] This application claims the priority of the Chinese patent application with the application number 200910236026.5 filed by the applicant on October 16, 2009. Technical field [0002] The invention relates to a motion conversion mechanism, in particular to a mechanism for mutual conversion between reciprocating motion and rotary motion. The present invention also relates to the components constituting the above-mentioned mechanism and the equipment obtained by using the above-mentioned mechanism. Background technique [0003] In mechanical equipment, it is necessary to realize the mutual conversion between reciprocating motion and rotating motion in many occasions. For example, a reciprocating internal combustion engine needs to convert the reciprocating linear motion of the piston generated by the explosive pressure of the combustible mixture into the rotation of the crankshaft; on the contrary, the compressor needs to convert the rotation of the crankshaft driven by an ext...
