Problems solved by technology

[0004] Most variable speed transmissions in the prior art cannot achieve zero gear ratio
Moreover, some pulse governors must turn off the driving motor when the speed is adjusted, which is very inconvenient in many cases.

Embodiment Construction

[0013] The invention will be described in more detail below with reference to an embodiment shown in the accompanying drawings.

[0014] In the illustrated embodiment, the stepless pulsation speed regulation transmission device of the present invention includes three cranks 2, one end of which is fixed on the input shaft, and the other ends are spaced apart with equal phase difference (here the phase difference is 120 degrees). Open, and hinged with a first connecting rod 3 respectively, the other end of each first connecting rod 3 is respectively hinged with a second connecting rod 5 and a second rocking bar 4, and the other end of each second connecting rod 5 is respectively connected with A first rocking lever 6 is hinged, and all first rocking levers 6 are all connected with an overrunning clutch 12, and the central shaft of the overrunning clutch 12 is fixed on the output shaft, and drives the output shaft to rotate. The other end of each second rocking rod is hinged with...

Abstract

The stepless pulsed speed regulating transmission mechanism includes three cranks and each one end of the cranks fixed to the same input shaft and the other end separated by one equal phase difference and hinge jointed with one first link lever separate, one separately second link lever, one separate first rocker, one separate second rocker and one identical overrunning clutch successively. The central shaft of the overrunning clutch is fixed onto the output shaft for rotating the output shaft. Each of the other end of the second rocker is hinged with one sldie block, one pulling rod and one screw nut around one screw bolt, which can rotate on one chassis and is fixed to one handle. The screw unit is driven by the rotating handle to move linearly and the slide block is made to move inside one arced slot to realize stepless speed regulation.

Description

technical field [0001] The invention relates to a stepless pulsation speed regulation transmission device, in particular to a connecting rod type stepless pulsation speed regulation transmission device, which is widely used in transport vehicles, conveying machinery, machine tools, textile machinery, metallurgy, chemical industry and textile industries. field. Background technique [0002] Most of the continuously variable speed transmission devices use friction transmission, which has the disadvantages of short service life and limited speed range. In recent years, someone has also developed a connecting rod transmission type stepless speed regulating device. CN2092632U discloses a typical connecting rod transmission type stepless speed regulation transmission device. This stepless speed regulating device includes an eccentric wheel, a first connecting rod fixed to rotate with the eccentric wheel, a second connecting rod hinged with the first conne...
