Background technique
Gear drive is conventional mechanical transmission, has multiple different form and kind.But current existing fixed axis gear driving mechanism can only be realized the transmission between the fixing two-parallel axis of relative position, for example, for the cylinder gear speed reducer of gearing down between two-parallel axis, its distance between shafts depends on reduction speed ratio and driving and driven design of gears, cannot change.And can change the driving mechanism of distance between shafts, as Schmidt's coupling etc., function singleness, cannot realize slow down or the level of integration of the function ，Qie mechanism of speedup not high.
Summary of the invention
Technical problem to be solved by this invention is that a kind of distance between shafts continuous variable gear drive based on planar linkage will be provided, solve existing gear drive and cannot realize the deficiency that distance between shafts changes, when keeping stable drive ratio, realize the continuous variation of input, output shaft spacing, be applicable to increasing, gearing down occasion that distance between shafts changes demand.
In order to solve above technical problem, the invention provides a kind of distance between shafts continuous variable gear drive based on planar linkage, comprise the first planar linkage and the second planar linkage, input shaft, jack shaft and output shaft, first order driving gear, first order driven gear, second level driving gear and second level driven gear.
The first planar linkage, the second planar linkage and jack shaft are hinged in jack shaft axis, and the first planar linkage, the second planar linkage and jack shaft can rotate freely around hinged central axis.
First order driving gear is installed on input shaft, input shaft and the first planar linkage are hinged in input shaft axis place, first order driving gear is also hinged in input shaft axis place with the first planar linkage by input shaft, and first order driving gear and input shaft can same angular velocity rotate freely around input shaft axis.
First order driven gear is installed on jack shaft, and second level driving gear is also installed on jack shaft, and first order driven gear, second level driving gear are also hinged in jack shaft axis with the first planar linkage, the second planar linkage by jack shaft.First order driven gear, second level driving gear and jack shaft can same angular velocity rotate freely around jack shaft axis.
Second level driven gear is installed on output shaft, output shaft is hinged in output shaft axis place with the second planar linkage, second level driven gear is also hinged in output shaft axis place with the second planar linkage by output shaft, and second level driven gear and output shaft can same angular velocity rotate freely around output shaft axis.
First order driving gear and first order driven gear are meshed, second level driving gear and second level driven gear are meshed, and power can be passed to output shaft from input shaft, first order driving gear, first order driven gear, jack shaft, second level driving gear, second level driven gear successively.
During this distance between shafts continuous variable gear drive work, the first planar linkage and the second planar linkage can become different amount around the rotation of jack shaft axis in the plane vertical with jack shaft axis, and the distance between shafts of input shaft and output shaft can realize continuous variation.This transmission ratio depends on the driving and driven gear ratio of the driving and driven gear ratio of the first order and the second level, has nothing to do with input, output shaft spacing.When the distance between shafts of input, output shaft changes continuously, velocity ratio remains unchanged.
Superior effect of the present invention is: realized input shaft, the stable drive ratio increasing of output shaft distance between shafts continuous variable, gearing down function.

Embodiment
Refer to shown in accompanying drawing, the invention will be further described.
As shown in Figure 1, the invention provides a kind of distance between shafts continuous variable gear drive based on planar linkage, comprise the first planar linkage 1 and the second planar linkage 2; Input shaft 3, jack shaft 4 and output shaft 5; First order driving gear 6, first order driven gear 7, second level driving gear 8 and second level driven gear 9.
The first planar linkage 1, the second planar linkage 2 and jack shaft 4 are hinged in jack shaft axis, and the first planar linkage 1, the second planar linkage 2 and jack shaft 4 can rotate freely around hinged central axis.
