Description
Technical field
The present invention relates to contiuously variable transmission, more particularly to a kind of hydrodynamic lubrication swash plate formed using plungers pump plunger principle
Helical gear contiuously variable transmission belongs to mechanical transmission technical field.
Background technology
Speed changer has a wide range of applications in industries such as light industry, chemical industry, weaving, food, sewage disposals, main to include machinery
Formula speed changer and electronic type speed changer.Wherein, mostly using driving band type or planetary structure formula in mechanical continuously-variable transmission
Transmission principle.Due to the easy aging of the transmission belt of driving band type speed changer or fatigue, the damage of speed changer is easily caused.And planet knot
Volume is relatively large for the speed changer structure of structure formula, and needs hydraulic control unit, therefore substantially limits its scope of application, and work
Make reliability and do not easily cause damage by force.Chinese invention patent ZL200510132746.9 discloses a kind of coaxial connecting rod stepless arteries and veins
Dynamic speed changer, using oblique circular cylinder formula eccentric wheel, the exterior contour of this eccentric wheel is an oblique circular cylinder.In this form of implementation
In, the slip ring sleeve on the oblique circular cylinder side of eccentric wheel, coincide by the side view of centre bore and oblique circular cylinder.That is, the center
The Kong Weiyi gradient inclined hole identical with oblique circular cylinder.If realizing zero gear ratio, the one of the oblique circular cylinder eccentric wheel can be made
A bottom surface and input shaft are concentric.This speed changer overcomes complicated, huge, of high cost, the maintenance difficult of manufacture, rotating ratio tune
The section deficiency of the prior art such as more difficult, is not only simple in structure compact, and manufactures and repair is all simple and at low cost, especially
That it can provide low-down minimum speed ratio, for example, minimum speed ratio is zero, that is, rotating ratio ranging from from zero to setting
The maximum (top) speed ratio of meter；Moreover, not only can shut down when speed change, can also in machine run speed change.But this pulsation becomes
Depending on the ripple amplitude of fast device is because of the quantity of connecting rod, the amplitude requirement of pulsation is smaller, then the quantitative requirement of connecting rod is more, conversely,
The amplitude requirement of pulsation is bigger, then the quantitative requirement of connecting rod is fewer, since this pulsation speed variator is limited by its own structure
System, the quantity of shown connecting rod can not possibly be set very much, this just substantially limits the lower limit of ripple amplitude.
Chinese invention patent ZL200910210481.8 discloses a kind of swash plate guide-rod stepless transmission, belongs to mechanical
Transmission technology field.According to the invention, swash plate guide-rod stepless transmission is by driving mechanism, output mechanism, babinet（15）Group
Into driving mechanism is by the adjustable swash plate of gradient（12）It is formed with the guide rod of three or more isogonism settings, three guide rods one
With unidirectional rotatable helical gear, other end is withstood in swash plate disk, and can do circumferential slippage in swash plate disk.Output machine
Structure is by the output shaft that one-directionally rotates（2）Be fixed in output shaft（2）Helical gear in upper and driving mechanism（4）The big helical teeth of engagement
Wheel（3）It forms.Export it is steady and it is small be the contiuously variable transmission a big feature.Since the comparison of resistance of speed adjusting gear is small,
Therefore the transformation of rotating speed can be carried out in transmission duty, can also be carried out when speed changer is stopped, this is the stepless change
Another big feature of fast device.But swash plate in the invention（12）With guide rod（7）Moving contact surface between for sliding friction, not only
Frictional resistance is big and be easy to cause the secondary abrasion of friction, so that the working life of speed changer is greatly reduced, while also can
Reduce the transmission accuracy and transmission efficiency of speed changer.
