Technical field
The present invention relates to a kind of novel transmission mechanism, particularly fully utilize planet synchronous pulley and Hooks coupling universal coupling transmission principle and a kind of novel transmission mechanism that can make universal deceleration or reverse speedup of inventing.
Background technique
Retarder is the mechanical transmission of using always, and its driving mechanism kind is also a lot.But existing various retarder product all can only provide relative position fixing between centers gearing down.Such as, cylindrical gear mechanism generally provides the transmission conversion between the fixing two-parallel axis of relative position; Common straight-tooth bevel gears can be used for the transmission conversion of two fixing crossing between centers of relative position; Worm reducer or spiral gear mechanism generally are used for the gearing down of two fixing vertical interlaced between centers of relative position.In the existing retarder product, the gearing down when only generally being difficult to realize that concurrent aces or alternating axis are got the disalignment angle of cut with a kind of retarder.Intersect arbitrarily or arbitrarily during the gearing down between alternating axis when producing the actual machine driven system implementation space that requires, generally need the various dissimilar reducing gears of combination, also need the Hooks coupling universal coupling mechanism (as Hooks coupling universal coupling in the vehicle transmission and transmission shaft) of series connection specially sometimes.Like this, tend to that the transmission shaft of mechanical system is increased, the between centers connecting relation is numerous and diverse.
Summary of the invention
The present invention seeks to: propose a kind of novel planetary synchronous pulley driving mechanism with universal deceleration or reverse speedup transmission agency, it can adapt to two concurrent aceses or the deceleration between two alternating axiss or the speedup transmission of the disalignment angle of cut, even and between the transmission shaft crossed axis angle change do not influence the drive connection of two between centers yet.
