Description
Technical field
The present invention relates to a kind of dental handpiece heads.
Background technology
Dental handpiece heads on the market are made up of shell, turbine, bearing at present, and turbine footpath jumps serious in current product,
The too small inner body in Element Design space is easy to be adjacent to head side wall influence rotational efficienty, and space crosses conference and causes air-flow excessive
Influence rotation efficiency.Miniature bearing cost used in other dental handpiece is too high, the strong influence use of dental handpiece
Cost, is that the popularization of disposable dental handpiece causes great obstruction.On the other hand, the inner ring outer ring of current bearing is used
Metal material, production cost is high, and the friction of ball and metal in the running can produce sharp noise.Used in dental handpiece
Bearing rotating speed can reach 300,000 turns per minute, and full-automatic production can't be realized at present for this high-precision bearing.
The content of the invention
In order to overcome existing dental handpiece design unreasonable, cost is too high, and used bearing can produce sharp noise
Deficiency, the present invention provides a kind of novel dental handset machine head.
The present invention solve its technical problem technical scheme be：On novel dental handset machine head, including shell, the shell
End cap, which is provided with end cap, the shell, is provided with turbine assembly, and block, the block are equipped with end cap lower surface in the shell
Inwall is provided with ball grooves, and the side opening of ball grooves one, the 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 and be clamped with two ends so that turbine runs at high speed in head internal stability, whirlpool
The gap taken turns with casing is also extremely easily controlled.
It is further used as preferably, the turbine assembly includes turbine, the axostylus axostyle being interspersed on turbine and is set in axostylus axostyle
On bearing inner race, retainer, through hole of the retainer provided with placement ball, the guarantor are arranged with the bearing inner race
Closing on the outside of frame through hole is held, ball is limited in through hole.By ball, retainer, bearing inner race, which is wholely set, simplifies assembling step
Suddenly so that dental handpiece can realize automated production, the production in enormous quantities of product is realized, reduces labour cost, reduction production
The production cost of product.
It is further used as preferably, the block upper end edge convex in shell is provided with flange collar, the block lower end of end cap lower end
Edge convex is provided with flange collar.
It is further used as preferably, the block lower end in shell is provided with choke face, 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, circular arc excessively place is provided with O-ring to flange collar.Using O-ring so that lid
Cap steadily can be arranged in shell, on the one hand also function to the purpose for clamping turbine assembly, be greatly reduced footpath and jumped so that 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 sets rubber washer to enter
One step has ensured the clamping degree of turbine so that block, which is fixed, more to be consolidated, and is greatly reduced footpath and jumps so that turbine wheel shaft is operated more
Plus it is steady.The setting of rubber washer can reduce the vibrations of block, increase damping, so as to reduce noise.
It is further used as preferably, the block is made of abrasion resistant fibrous.Using the abrasion resistant fibrous block processing side being made
Just, it can be made of Shooting Technique and reduce production cost, the use of lubricant fiber in addition can ensure the operating stream of ball
Smooth property keeps the running efficiency of turbine.
In the use of the present invention, rubber washer is respectively disposed on shell and end cap, O-ring is set in block and
The block for being arranged with O-ring is placed in shell and on end cap afterwards, end cap is covered tightly after turbine assembly is loaded to be installed
Finish.
The beneficial effects of the present invention are：Cap sealed is splendid, and the design of block upper convex ring forms form of flanges so that
Turbo driving is more steady, the setting of cap material cause with ball flexible friction, reduce noise, can be reduced to after tested
Few more than 5 decibels, step is simply easily manufactured, it is adaptable to automated production, reasonable in design, and turbine rotation efficiency is great
Improve, effect of optimization is good, overall operation is stable.Present invention is designed such that the cost performance of dental handpiece reached it is ultimate attainment.
