Example Embodiment

[0014] The following will refer to figure 1 A specific embodiment of the present invention will be described.

[0015] like figure 1 As shown, it is similar to the traditional incomplete gear transmission mechanism. The driven wheel 5 and the positioning index plate 4 are fixedly connected with the rotating shaft through the keyway, so that the index plate and the driven wheel keep rotating synchronously. The index plate 4 is provided with 4 holes, and 4 identical magnetic positioning pins 6 are symmetrically embedded and installed in the 4 holes of the positioning index plate 1 at intervals of 90° along the circumferential direction, and the axes of the magnetic positioning pins 6 and the index plate The axes of 4 are parallel, and 2 positioning magnets are installed on the positioning frame 8. When the centerlines of the magnetic positioning pins 6 and two positioning magnets coincided, the positioning magnets and the magnetic positioning pins 6 were not in contact with e...

Abstract

The invention discloses a magnetic vibration damping and positioning incomplete gear, relating to the field of intermittent drive mechanisms. The magnetic vibration damping and positioning incomplete gear comprises an incomplete gear drive wheel (1), an index plate (4), an incomplete gear driven wheel (5), a positioning frame (8), a stand, a vibration damping magnet A (2), a vibration damping magnet B (3), a magnetic positioning pin (6) and a positioning magnet. Compared with the prior art, the invention greatly improves the reliability and the stability and has the advantages of simple mechanism structure and long service life.

Description

technical field [0001] The invention relates to the field of incomplete gear transmission mechanisms, in particular to an incomplete gear transmission mechanism with a magnetic force damping device and a magnetic force positioning device. Background technique [0002] The incomplete gear mechanism is an intermittent motion mechanism evolved from the ordinary involute gear mechanism. For the intermittent motion of the driven wheel. Incomplete gears are widely used in food, medicine, packaging and other mechanical equipment. [0003] However, incomplete gears also have their disadvantages: first, the sudden change in the speed of the teeth of the driving wheel and the driven wheel when they contact will produce instantaneous impact vibration, which is easy to cause damage to the teeth; secondly, when the driving and driven wheels stop moving, it will also A sudden change in speed occurs, and the locking arc will generate impact vibration with the driving wheel during the loc...
