Background technology
In general, head as the air type topping machanism of dental, on its top, have head, parts at the in-built cutting element being necessary of this head, comprise the armature spindle of cutting element, support two bearings of gyroaxis and be configured in two impellers between bearing portion, make to impact impeller and make cutting element revolution from being configured in the pressure-air of supplying with to gas circuit in the handle portion of head.The rotor shaft of existing disposable dental drill and blade are all integrated injection plastics, as the utility model patent of the patent No. 200520045733.3, its rotor shaft is to coordinate by three lobe springs with car pin, the utility application of application number 200910001394.1, the car pin hole of its rotor shaft is set to spline-shaped, by the elastic force clampingc car shank of plastics, this patent arranges former of choke in addition, increase rotary inertia, other disposable dental drill is also selected car pin hole and car shank interference fit etc., these structures, because the precision of China's injection mold is generally 0.04-0.06mm, the ratio of precision injection mold of metal die-casting mold is low, the parts precision of injection moulding or die casting is just poorer, under per minute 300,000 environment that turn, because the quality that low precision produces is inhomogeneous, occur uneven, cause vibration, produce noise, do not meet standard, just there is no actual use.
Utility model content
The purpose of this utility model is the dynamic equilibrium problems when solving the movement high speed rotating of existing dental drill.
For achieving the above object, this utility model is by the following technical solutions:
A dental turbine unit movement, is comprised of head shell, wind wheel and bearing, and wind wheel comprises rotor shaft and wind wheel blade, and described rotor shaft is established dynamic balancing hole in end, the built-in dynamic balancing body in dynamic balancing hole.
Described rotor shaft is established wind wheel axis hole, and wind wheel axis hole inner clip ZHUANLIAN connects jaw bar, and jaw boom end stretches out wind wheel axis hole and in jaw boom end, establishes dynamic balancing hole, the built-in dynamic balancing body in dynamic balancing hole.
Between described dynamic balancing body and described dynamic balancing hole, establish rubber or sponge.
Described rotor shaft is established splined hole in end, splined hole internal clearance matching spline, and spline stretches out fixedly dynamic balancing dish of splined hole.
Described rotor shaft is established wind wheel axis hole, and wind wheel axis hole inner clip ZHUANLIAN connects jaw bar, and jaw boom end stretches out wind wheel axis hole and establish splined hole in jaw boom end, splined hole internal clearance matching spline, and spline stretches out fixedly dynamic balancing dish of rotor shaft end.
Described spline is spherical spline, and the spline of spherical spline is axially circular arc on ball surface along turbine wheel shaft and distributes; With the splined hole of spherical spline fitted be ball cavity splined hole, be the spline with spherical spline fitted in ball cavity splined hole.
Between described spline and described splined hole, establish rubber or sponge.
Adopt this utility model of technique scheme, in rotor shaft, establish dynamic balancing body, keep the original size constancy of dental drill profile, the imbalance of rotating part is adjusted automatically; If splined hole, splined hole internal clearance matching spline, spline stretches out fixedly dynamic balancing dish of rotor shaft end, dynamic balancing dish regulates dynamically balanced amount large, even if the unbalanced amount of wind wheel is larger, and the part of die cast for example, also can automatically regulate, reduce the cost of high accuracy processing.
Accompanying drawing explanation
Fig. 1 this utility model is established dynamic balancing body structure schematic diagram;
Fig. 2 this utility model is established syndeton schematic diagram between flower;
Fig. 3 this utility model is established syndeton schematic diagram between globular flower.
The specific embodiment
As Fig. 1, a kind of dental drill head, by head shell 1, wind wheel and bearing 2, formed, wind wheel comprises rotor shaft 3 and wind wheel blade 4, and described rotor shaft 3 is established wind wheel axis hole, establishes jaw 9 and connect jaw bar 10 in wind wheel axis hole, jaw bar 10 ends are stretched out wind wheel axis hole and establish dynamic balancing hole 12 in jaw bar 10 ends, the interior encapsulation dynamic balancing in dynamic balancing hole 12 body 13, matched in clearance between dynamic balancing body 13 and dynamic balancing hole 12, dynamic balancing body 21 moves radially the dynamic balancing that automatically regulates wind wheel in dynamic balancing hole 12.The shape of dynamic balancing body 21 can be column, and for example cylinder, prism, can be also spherical or irregular particle shape.
Between dynamic balancing body 13 and dynamic balancing hole 12, establish soft rubber or sponge 20, soft rubber is as silica gel, polyurethane etc., and sponge is its foamed material.Make flexible cooperation between dynamic balancing body 13 and dynamic balancing hole 12.
Above-described embodiment is the structure of pressing loading-unloading vehicle pin dental drill, dental drill for plug or key loading-unloading vehicle pin, in rotor shaft end, establish dynamic balancing hole 12, the interior encapsulation dynamic balancing in dynamic balancing hole 12 body 13, but balanced body 13 is axially established the car pin hole keyhole UNICOM in through hole and rotor shaft.
As shown in Figure 2, jaw bar is established splined hole 21 in 10 ends, splined hole 21 internal clearance matching splines 22, and spline 22 stretches out fixedly dynamic balancing dish 23 of splined hole 21, establishes soft rubber or sponge 20 between spline 22 and splined hole 21.Spline 24 in splined hole 23 radially the moving dynamic balancing disc radial of moving belt move and automatically regulate the dynamic balancing of wind wheel.Equally, dental drill for plug or key loading-unloading vehicle pin, in rotor shaft end, establish splined hole 21, splined hole 21 internal clearance matching splines 22, spline 22 stretches out fixedly dynamic balancing dish 23 of rotor shaft end, but spline 22 is axially established car pin hole or the keyhole UNICOM in through hole and rotor shaft with dynamic balancing dish 23.Adjust so dynamically balanced great efforts, the movement of die cast metal can both be adjusted.
