Abstract
The invention discloses a kind of curved rack damping composite driving mechanism, including gear, curved rack, damping rail, end-rack, gear has upper teeth portion, curved rack has lower teeth portion, and the upper teeth portion is circumferentially provided with least two mating grooves along gear, and end-rack is located at gear exterior, the end-rack has damping rail with screw connection, arc where the damping rail, mating groove, curved rack is parallel, and when upper teeth portion and lower teeth portion coordinate, damping rail also coordinates with mating groove.The matching mechanism of gear and curved rack is introduced a damping mechanism by the present invention, is reduced the idle running influence of transmission, is had the advantage of two kinds of mechanism drivings concurrently, is particularly suitable for use in the mechanical structure for not only needing load-carrying but also needing to be driven without idle running.
Description
Technical field
The present invention relates to gear, rack field, more particularly to a kind of curved rack damping composite driving mechanism.
Background technology
Rack is that rack also divides spur rack and diagonal-cut rack with a series of flat boards or straight-bar for equidistantly distributing tooth,
Used respectively with straight spur gear and helical gears pairing.It is combined through gear drive with rack-driving, more particularly to
During linear transmission, frequently with the kind of drive of rack pinion, have the advantages that transport is steady, step pitch is calibrated, have load-carrying concurrently.In order to
Its service life can be improved by preventing the abrasion, spot corrosion, gluing of rack and pinion, and the lubrication for rack and pinion is particularly important.
Gear and rack carry out machine driving often as a kind of mechanism, and mechanical efficiency is high, durable.But for some fine
The cooperation of governor motion, gear and rack no longer meets requirement.In some mechanical transmission mechanisms, not only needed certain load-carrying but also
Stable damping is needed, idle running is prevented, the cooperation gearratio spur rack of curved rack and pinion is unstable, it would be highly desirable to improves, therefore opens
Send out gear a kind of and under the premise of curved rack coordinates, be re-introduced into damping transmission, namely anodontia and with teeth combination, it is excellent with reference to both
Point, is that machine driving introduces new constructive scheme.
The content of the invention
It is an object of the invention to provide a kind of curved rack damping composite driving mechanism, the cooperation of transformation gear and curved rack
Mechanism, with reference to the advantage of damping transmission, to overcome problems of the prior art.
In order to realize the above object the technical scheme is that：
A kind of curved rack damping composite driving mechanism, including gear, curved rack, damping rail, end-rack, gear has upper teeth portion, curved
Rack has lower teeth portion, and the upper teeth portion is circumferentially provided with least two mating grooves along gear, and end-rack is located at gear exterior, described
End-rack has damping rail with screw connection, and the arc where the damping rail, mating groove, curved rack is parallel, in upper teeth portion and lower tooth
When portion coordinates, damping rail also coordinates with mating groove.
Preferably, the mating groove quantity is 2 ~ 3, mating groove is equally spaced in the centre position in outer peripheral gear face.Match somebody with somebody
Close slot number amount and do not destroy structure, centre position destroys smaller to teeth portion, is driven impacted minimum, stable transmission after transformation.
Preferably, the damping rail is the rope or bar of resisting medium, resisting medium is butyl rubber, silicon rubber, poly- ammonia
One kind in ester foam, copper-zinc-aluminum series alloy, iron-chromium-molybdenum system alloy, manganese-copper series alloy.
Preferably, the upper teeth portion and lower teeth portion are helical teeth.Seize gearratio straight-tooth on both sides by the arms more stable.
Preferably, the cooperation rooved face scribbles damping paint.Damping paint strengthens damping capacity.
The beneficial effects of the present invention are：The present invention is simple in construction, transmission novelty has feature.Gear, curved rack coordinate, with
The cooperation for damping rail and end-rack is reliable and stable；Opening a plurality of mating groove coordinates damping rail both not destroy structure, moreover it is possible to play very well
Damping fiting effect, coordinated with frictional force part limiting gear rack and be driven, improve transmission stability, reduce rack-driving
Idle running；The distance between screw regulation damping rail and end-rack, convenient regulation amount of resistant.Cooperation of the invention by gear and curved rack
Mechanism introduces a damping mechanism, reduces the idle running influence of transmission, has the advantage of two kinds of mechanism drivings concurrently, be particularly suitable for use in both
Load-carrying is needed to need the mechanical structure being driven without idle running again.
