Abstract
The invention relates to a movement of a dental high-speed turbine handpiece. The movement comprises a rotating shaft, and a wind wheel and two bearings which are sleeved on the rotating shaft, the bearings are respectively positioned at two sides of the wind wheel, positions on a cylinder corresponding the bearings are respectively provided with an annular groove, an O-shaped rubber ring is arranged in the annular groove, and the O-shaped rubber ring is made by using a fluorubber material. The movement of the dental high-speed turbine handpiece has the advantages of stable running and long service life.
Description
Technical field
The present invention relates to dental handpiece, be specifically related to the movement of high speed dental turbo mobile phone.
Background technology
The high speed dental turbo mobile phone is a kind of cutting of the high speed rotating with air stream drives medical apparatus and instruments, turns 200,000 rev/mins～600,000 rev/mins of scooters and does not wait, and it is mainly used for cutting the tooth body, prepares tooth cavity, prepares thread form and finishing thread form etc.
The high speed dental turbo mobile phone mainly is comprised of with the head be connected with handle handle, handle inside is provided with water inlet pipe, air inlet pipe and return gas channel, head comprises shell and interior movement thereof, movement comprises cylindrical shell, rotating shaft, be sleeved on wind wheel and 2 bearings in rotating shaft, bearing lays respectively at the both sides of wind wheel, on cylindrical shell, the position of corresponding bearing is respectively arranged with annular groove, be provided with " O " type cushion rubber in annular groove, play rigid bearing and prevent between bearing and cylindrical shell occurring the effect firmly contacted.The impact of the overall performance for the high speed dental turbo mobile phone of " O " type cushion rubber is extremely important, and elasticity is crossed conference and caused in high speed dental turbo operating handset process unstablely, and the phenomenon of vibration is arranged; Elasticity is too small, and " O " type cushion rubber can't play the effect of damping, buffering, can cause equally in high speed dental turbo operating handset process unstable.Existing " O " type cushion rubber is made by nitrile rubber, and the performances such as high temperature resistant, oil resistant, resistance to abrasion are inadequate, yielding aging, after long-time the use, can cause the movement fluctuation of service, and shorten service life.
Fluorubber (fluororubber) refers to the synthetic rubber that contains fluorine atom on the carbon atom of main chain or side chain, the characteristic that fluorubber has is high temperature resistant, oil resistant and the medicine of anti-the number of chemical corrode is the indispensable materials of most advanced branches of science technology such as modern Aviation, guided missile, rocket, space travel.Du Pont (DuPont) VITON A fluorubber also claims fluororubber 26, is commonly called as glue No. 2, is copolymer from vinylidene fluoride and hexafluoropropylene.
Summary of the invention
The purpose of this invention is to provide a kind of operation more stable, the movement of the high speed dental turbo mobile phone of longer service life.
For solving the problems of the technologies described above, the present invention is by the following technical solutions: the movement of high speed dental turbo mobile phone, comprise cylindrical shell, rotating shaft, be sleeved on wind wheel and two bearings in rotating shaft, described bearing lays respectively at the both sides of wind wheel, and on cylindrical shell, the position of corresponding bearing is respectively arranged with annular groove, be provided with " O " type cushion rubber in annular groove, described " O " type cushion rubber is that the fluorubber material is made.The VITON A of the preferred Du Pont of fluorubber fluorubber.
In order to strengthen the stable of movement operation, be provided with top in the bottom of described cylindrical shell and be pressed in the saddle type bullet pad on bearing.
Adopt the movement of the high speed dental turbo mobile phone of technique scheme, O type circle in movement adopts fluorubber to make, the VITON of Du Pont A fluorubber particularly, there is the performances such as good high temperature resistant, oil resistant, resistance to abrasion and incompressible permanent deformation, still can keep good moderate elastic force after long-time the use, the movement operation is more stable; The bottom of cylindrical shell is provided with top and is pressed in the saddle type bullet pad on bearing, plays the effect of damping, buffering when the high speed dental turbo mobile phone stops running up, shortens the time that rotating shaft stops fully from running up, thereby greatly extends the life-span of movement.
The accompanying drawing explanation
The cut-away view that Fig. 1 is one embodiment of the present invention.
Number in the figure is: 1 cylindrical shell; 2 rotating shafts; 3 wind wheels; 4 bearings; 5 " O " type cushion rubber; 6 saddle type bullet pads.
The specific embodiment
The movement of high speed dental turbo mobile phone of the present invention, comprise cylindrical shell 1, rotating shaft 2, be sleeved on wind wheel 3 and two bearings 4 in rotating shaft 2, described bearing 4 lays respectively at the both sides of wind wheel 3, on cylindrical shell 1, the position of corresponding bearing 4 is respectively arranged with annular groove, is provided with " O " type cushion rubber 5 in annular groove, and described " O " type cushion rubber 5 is made for the fluorubber material.The preferred VITON A of fluorubber fluorubber.In order to strengthen the stable of movement operation, be provided with top in the bottom of described cylindrical shell 1 and be pressed in the saddle type bullet pad 6 on bearing 4.
Claims (3)
1. the movement of high speed dental turbo mobile phone, comprise cylindrical shell, rotating shaft, be sleeved on wind wheel and two bearings in rotating shaft, described bearing lays respectively at the both sides of wind wheel, on cylindrical shell, the position of corresponding bearing is respectively arranged with annular groove, is provided with " O " type cushion rubber in annular groove, it is characterized in that: described " O " type cushion rubber is that the fluorubber material is made.
