Abstract
The invention relates to a high-speed turbine handpiece movement for the dental department. The high-speed turbine handpiece movement comprises a rotating shaft, a wind wheel and two bearings, wherein the rotating shaft is sleeved with the wind wheel. Each bearing comprises an outer ring, an inner ring, a retainer and a plurality of balls, wherein the balls are arranged in the circumferential direction of the retainer. Rollway surfaces are arranged on the inner circumferential surfaces of the outer rings and the outer circumferential surfaces of the inner rings, and platforms which stretch towards the inner sides are arranged on the upper portions of the outer rings of the bearings. The high-speed turbine handpiece movement for the dental department is not prone to being damaged, easy to assemble and long in service life.
Description
Technical field
The present invention relates to dental handpiece, be specifically related to a kind of high speed dental turbo mobile phone core.
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 rotating shaft, be sleeved on wind wheel and 2 bearings in rotating shaft, described 2 bearings lay respectively at the two ends of wind wheel.In the composition of existing dental handpiece movement, described bearing comprises outer ring, inner ring, retainer and is arranged at the some balls on the retainer circumferencial direction, all there is roller surface on the inner peripheral surface of described outer ring and the outer peripheral face of inner ring, inner ring and outer ring are the hollow cylinder shape, and retainer is arranged between inner ring and outer ring.
The bearing that existing high speed dental turbo mobile phone core is used, carry out proofing dust and protecting according to whether to ball and be divided into two kinds, open type bearing and combination type bearing with cover.The outside of the retainer of open type bearing between inner ring and outer ring does not arrange dust cap, and the foreign material that some granules are larger can be inhaled into retainer the inside, cause ball rotate dumb, be abraded damage etc., thereby shortened the service life of bearing.Combination type bearing with cover is between inner ring and outer ring, be provided with independently dust cap above retainer, can prevent that foreign material that some granules are larger from entering retainer inside and touching ball, avoid retainer and ball to damage, extended the service life of bearing, but still will reserve larger gap between the bearing cap of this structure and inside and outside circle, otherwise be difficult to assembling, and lid can rub with inner ring when high speed dental turbo mobile phone high speed rotating is worked.The assembling trouble of combination type bearing with cover, high to assembly crewman's technical ability requirement, production efficiency is low.In addition, the ball used in existing bearing is made for metal, because the each use of high speed dental turbo mobile phone all will be passed through autoclave sterilization, in use steam can often be inhaled into bearing inside, after metal balls is repeatedly used, the ball abrasion of easily getting rusty, shortened service life of high speed dental turbo mobile phone.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of not fragile, and assembling is simple, the high speed dental turbo mobile phone core of longer service life.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
A kind of high speed dental turbo mobile phone core, comprise rotating shaft, be sleeved on wind wheel and 2 bearings in rotating shaft, described bearing comprises outer ring, inner ring retainer and is arranged at the some balls on the retainer circumferencial direction, all have roller surface on the outer peripheral face of the inner peripheral surface of outer ring and inner ring, it is characterized in that: the top, outer ring of described bearing is provided with extendable platform to the inside.
In technique scheme, the outer ring of the described bearing internal diameter after extendable platform to the inside is less than the external diameter of described bearing inner race.
In technique scheme, the ball of described bearing adopts hard ceramic material to make.
Adopt a kind of high speed dental turbo mobile phone core of technique scheme, the extendable platform to the inside that the bearing outer ring top of using in movement arranges, played the effect of dust cap, do not need to use independent dust cap, its dustproof gap is very little, and dust-proof effect is better, longer service life; Assembly process reduces, and assembling process is simpler than the assembling of combination type bearing with cover; Use hard ceramic balls in bearing, the damage that is difficult for getting rusty, can increase the service life greatly.
The accompanying drawing explanation
The cut-away view that Fig. 1 is one embodiment of the present invention middle (center) bearing.
Number in the figure is: 1 outer ring; 2 inner rings; 3 retainers; 4 balls.
The specific embodiment
A kind of high speed dental turbo mobile phone core of the present invention, comprise rotating shaft, be sleeved on wind wheel and 2 bearings in rotating shaft, described bearing as shown in Figure 1, comprise outer ring 1, inner ring 2, retainer 3 and be arranged at the some balls 4 on retainer 3 circumferencial directions, all there is roller surface on the outer peripheral face of the inner peripheral surface of outer ring 1 and inner ring 2, the top, outer ring of described bearing is provided with extendable platform to the inside, the described outer ring internal diameter after extendable platform to the inside is less than the external diameter of described bearing inner race, and the ball of described bearing adopts hard ceramic material to make.
Claims (3)
1. a high speed dental turbo mobile phone core, comprise rotating shaft, be sleeved on wind wheel and 2 bearings in rotating shaft, described bearing comprises outer ring, inner ring, retainer and is arranged at the some balls on the retainer circumferencial direction, all have roller surface on the outer peripheral face of the inner peripheral surface of outer ring and inner ring, it is characterized in that: the top, outer ring of described bearing is provided with the platform extended to the inside.
2. a kind of high speed dental turbo mobile phone core according to claim 1 is characterized in that: the outer ring of the described bearing internal diameter after extendable platform to the inside is less than the external diameter of described bearing inner race.
