Abstract
The invention provides a novel dental handpiece nose, which comprises a shell, wherein the upper end of the shell is covered by an end cover; the shell is internally provided with a turbine component; the interior of the shell and the lower end surface of the end cover are provided with cover caps; the inner walls of the cover caps are provided with ball grooves; one side of each ball groove is provided with an opening; the cover caps can directly sleeve two ends of the turbine components. Two ends of the cover caps can directly sleeve the turbine component and are clamped tightly, so that the turbine can run stably at a high speed in the nose; and a clearance between the turbine and an enclosure is also quite easy to control. The cover cap airtightness is excellent; convex rings on the cover caps are designed in a flange shape, so that the turbine is enabled to run more stably; due to the material of the cover caps, the cover caps are in flexible friction with balls, so that noises are reduced; according to tests, the noises can be reduced by at least 5dB; steps are simple, the novel dental handpiece nose is convenient to manufacture, suitable for automatic production, reasonable in structural design, greatly improved in turbine rotation efficiency and good in optimization effect and stable in integral run. Due to the design, the cost performance of the dental handpiece is maximal.
Description
Technical field
The present invention relates to novel dental handset machine head.
Background technology
Dental handpiece heads on the market are made up of shell, turbine, bearing at present, and in current product, turbine footpath is jumped seriously,
The too small inner body in Element Design space is easy to be adjacent to head side wall impact rotational efficienty, and space is crossed conference and causes air-flow excessive
Impact rotation efficiency.In addition dental handpiece is used miniature bearing high cost, the strong influence use of dental handpiece
Cost, the popularization for disposable dental handpiece causes great obstruction.On the other hand, the inner ring outer ring of current bearing all adopts
Metal material, production cost is high, and ball and the friction of metal in the running can produce sharp noise.Dental handpiece is used
Bearing rotating speed can reach 300,000 turns per minute, can't realize full-automatic production at present for this high-precision bearing.
Content of the invention
In order to overcome existing dental handpiece to design unreasonable, high cost, the bearing being used can produce sharp noise
Deficiency, the present invention provide a kind of novel dental handset machine head.
The technical scheme that the present invention solves its technical problem is: novel dental handset machine head, including shell, on described shell
End cap is provided with end cap, and described inside the shell is provided with turbine assembly, and described inside the shell and end cap lower surface are equipped with block, described block
Inwall is provided with ball grooves, described ball grooves one side opening, and described block part can directly be set in turbine assembly two ends.Using this
The block of the form of kind can be set on turbine assembly with two ends and clamp so that turbine runs up in head internal stability, whirlpool
Wheel is also extremely easily controlled with the gap of casing.
It is further used as preferably, described turbine assembly includes turbine, the axostylus axostyle being interspersed on turbine and be set in axostylus axostyle
On bearing inner race, described bearing inner race is arranged with retainer, described retainer be provided with dispose ball through hole, described guarantor
Hold and close up outside frame through hole, ball is limited in through hole.By ball, retainer, bearing inner race is wholely set and simplifies assembling step
Suddenly so that dental handpiece is capable of automated production, realize the production in enormous quantities of product, decrease labour cost, reduce and produce
The production cost of product.
It is further used as preferably, the block upper end edge of inside the shell is outwards convexly equipped with flange collar, the block lower end of end cap lower end
Edge is outwards convexly equipped with flange collar.
It is further used as preferably, the block lower end of inside the shell is provided with choke face, and the block upper end of end cap lower end is provided with choke
Face.
It is further used as preferably, with outer wall circular arc excessively, the excessive place of circular arc is provided with o shape circle to flange collar.Make to cover using o shape circle
Cap can steadily be arranged on inside the shell, on the one hand also functions to clamp the purpose of turbine assembly, be greatly reduced footpath jump and make whirlpool
Wheel shaft operating is more steady.
It is further used as preferably, the top and bottom of two blocks are provided with rubber washer.Lateral surface setting rubber washer enters
One step has ensured the clamping degree of turbine so that block fixation is more firm, is greatly reduced footpath jump and turbine wheel shaft is operated more
Plus steadily.The setting of rubber washer can reduce the vibrations of block, increases damping, thus reducing noise.
It is further used as preferably, described block is made using abrasion resistant fibrous.Using the abrasion resistant fibrous block processing side made
Just, can be made using Shooting Technique and reduce production cost, the in addition use of lubricant fiber can ensure the operating stream of ball
Smooth property keeps the running efficiency of turbine.
The present invention, when using, rubber washer is respectively disposed on shell and end cap, o shape snare is located in block
Afterwards the block being arranged with o shape circle is placed on inside the shell and end cap, covering tightly end cap after turbine assembly is loaded can install
Finish.
The beneficial effects of the present invention is: cap sealed is splendid, the design forming form of flanges of block upper convex ring so that
Turbo driving is more steady, and the setting of cap material makes and ball flexible friction, reduces noise, can be reduced to after tested
Few more than 5 decibels, step simply easily manufactured it is adaptable to automated production, reasonable in design, turbine rotation efficiency is great
Improve, effect of optimization is good, and overall operation is stable.Present invention is designed such that the cost performance of dental handpiece reached ultimate attainment.
