Description
Technical field
The present invention relates to design of gears field, particularly a kind of gear assembly eliminating drive gap.
Background technique
Gear refers to have tooth can engage the mechanical component transmitting motion and power continuously on wheel rim.Gear is the intermeshing mechanical parts having tooth of energy, and the application of gear in transmission has occurred very early.In 19 end of the centurys, generate cutting ratio juris and utilize the special purpose machine tool of this principle cutting and the appearance in succession of cutter, along with the development of producing, the stationarity of gear operation comes into one's own.
Existing gear generally includes the gear teeth, teeth groove, end face.Existing gear is when engaging each other, due to problems such as manufacturing process or use wearing and tearing, the gear teeth between gear engage each other and there is gap, in the transmission process of reality, the defect that transmission stability is poor may be there is, and then also may produce the wearing and tearing and generation noise of between the gear teeth and the gear teeth, mutually clashing into the aggravation gear teeth.And when gear is applied to the environment needing to detect rotation angle, the existence of running clearance have impact on the testing precision of rotation angle.
Summary of the invention
Embodiment of the present invention goal of the invention is to provide a kind of gear assembly eliminating drive gap, applying this technological scheme can when gear engages each other, eliminate the drive gap between the gear teeth, improve the stability of transmission, reduce the rate of wear of the gear teeth simultaneously, improve the working life of gear, play the effect reducing noise simultaneously.
In order to realize foregoing invention object, complete skill scheme of the present invention is:
Eliminate a gear assembly for drive gap, comprise gear shaft, the first gear and the second gear; Described first geared sleeve is connected on described gear shaft, and the first gear and described gear shaft are interference fit; Described second geared sleeve is connected on described gear shaft, and the second gear coordinates for movable with described gear shaft; The right side of described first gear is provided with the first boss, described first boss offers the first inclined-plane; The left side of described second gear is provided with the second boss, described second boss offers the second inclined-plane; Described first inclined-plane contacts with described second inclined-plane.
Preferably, described gear shaft goes back mounting spring and controlling mechanism; Described spring is arranged between described second gear and described controlling mechanism, and make one end of described spring withstand the right side of described second gear, the other end withstands described controlling mechanism.
Optionally, described controlling mechanism is adjusting nut, and described adjusting nut and described gear shaft are threaded connection.
Optionally, described controlling mechanism is buckle.
Therefore, the embodiment of the present invention is by arranging the first gear and the second gear, first gear is fixed on gear shaft, first gear arranges the first boss, second gear arranges the second boss, when in use, the first inclined-plane that first boss is offered contacts with the second inclined-plane that the second boss is offered, because the first inclined-plane and the second inclined-plane form relative movement, active force makes the first gear and the second gear have trend in relative rotation, now the gear teeth of the first gear and the gear teeth of the second gear also do relative movement, the present embodiment is when being meshed with other gears, due to the first gear and the second gear relative movement, the end face of the gear teeth of the first gear contacts with the end face of the teeth groove of other gears, the bottom surface of the gear teeth of the second gear contacts with the bottom surface of the teeth groove of other gears, drive gap when now utilizing the relative movement of two gears to eliminate the present embodiment and other gears meshing, improve the stability of transmission, reduce the rate of wear of the gear teeth simultaneously, improve the working life of gear, play the effect reducing noise simultaneously.The elimination of gear clearance, improves the precision that rotation angle detects.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technological scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment 1:
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, present embodiment discloses the concrete structure of using state signal and the present embodiment, the present embodiment provides a kind of gear assembly eliminating drive gap, comprises gear shaft 100, first gear 110 and the second gear 120; First gear 110 is socketed on gear shaft 100, and the first gear 110 is interference fit with gear shaft 100; Second gear 120 is socketed on gear shaft 100, and the second gear 120 coordinates for movable with gear shaft 100, the right side of the first gear 110 is provided with on the first boss 111, the first boss 111 and offers the first inclined-plane 112; The left side of the second gear 120 is provided with on the second boss 121, second boss 121 and offers the second inclined-plane 122; First inclined-plane 112 contacts with the second inclined-plane 122.
The present embodiment is when reality uses, first gear 110 and the second gear 120 match with other gears 200 simultaneously, the end face of the gear teeth of the first gear 110 contacts with the end face of the teeth groove of other gears 200, the bottom surface of the gear teeth of the second gear 120 contacts with the bottom surface of the teeth groove of other gears 200, reduces drive gap thus.
More tight in order to make the first inclined-plane 112 contact with the second inclined-plane 122, make opposing force effect more remarkable, gear shaft 100 goes back mounting spring 130 and controlling mechanism 101; Spring 130 is arranged between the second gear 120 and controlling mechanism 101, and make one end of spring 130 withstand the right side of the second gear 120, the other end withstands controlling mechanism 101.
More particularly, controlling mechanism can be adjusting nut, and adjusting nut and gear shaft 100 can be threaded connection, and by rotating adjusting nut, adjusting nut is moved on gear shaft, realizes the effect of compression or pull-off spring.
The most simply, controlling mechanism can be buckle, and buckle can be fixed on gear shaft, plays spacing effect.
Above-described mode of execution, does not form the restriction to this technological scheme protection domain.The amendment done within any spirit at above-mentioned mode of execution and principle, equivalently to replace and improvement etc., within the protection domain that all should be included in this technological scheme.
