Abstract
The present invention relates to a kind of dental handpiece movement increasing block piece, this movement is installed in the handset machine head that is connected with cell-phone handle, comprise rotating shaft, be rotatingly sleeved on wind wheel in rotating shaft and two bearings, wherein two bearings are in the upper and lower of wind wheel respectively, on the top of handset machine head, cell phone rear cover is installed, air-flow in cell-phone handle drives wind wheel to rotate in handset machine head, is also all provided with the block piece that the air-flow blocked in described cell-phone handle blows in bearing between described wind wheel and described bearing.The invention has the beneficial effects as follows: between wind wheel and bearing, be provided with the block piece that the air-flow blocked in cell-phone handle blows in bearing, the air-flow preventing the trachea in handle from producing blows in bearing, the noise produced when reducing dental handpiece work, avoid the damage of foreign body quickening to bearing be mingled with in the gas flow, and after avoiding the grease of Bearing inner to be blown away, accelerate bearing wear damage.
Description
Technical field
The present invention relates to medical apparatus and instruments, be specifically related to a kind of dental handpiece movement increasing block piece.
Background technology
Dental handpiece a kind ofly cuts medical apparatus and instruments with the high speed rotating of air stream drives, and do not turn scooter 200,000 revs/min ~ 600,000 revs/min not etc., it is mainly used for cutting tooth body, prepares tooth cavity, prepares thread form and finishing thread form etc.
High speed dental turbo mobile phone forms primarily of handle and the head that is connected with handle, and handle inner is provided with water inlet pipe, air inlet pipe and return gas channel, and head comprises shell and interior movement thereof, and movement comprises rotating shaft, is sleeved on the wind wheel in rotating shaft and two bearings.Trachea generation air stream drives wind wheel high-speed rotary in handle transfers and cuts.In the composition of existing dental handpiece movement, sealing protection process is not done between wind wheel and bearing, the air-flow that trachea in handle produces can blow in bearing, abnormal sound is produced when causing dental handpiece to work, noise is large, the foreign body be mingled with in the gas flow also can accelerate the damage of bearing, and air-flow accelerates bearing wear damage after the grease of Bearing inner can be caused to be blown away.
Summary of the invention
In sum, in order to overcome existing technical problem, the invention provides a kind of dental handpiece movement increasing block piece.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of dental handpiece movement increasing block piece, this movement is installed in the handset machine head that is connected with cell-phone handle, comprise rotating shaft, be rotatingly sleeved on wind wheel in rotating shaft and two bearings, wherein two bearings are in the upper and lower of wind wheel respectively, on the top of handset machine head, cell phone rear cover is installed, air-flow in cell-phone handle drives wind wheel to rotate in handset machine head, is also all provided with the block piece that the air-flow blocked in described cell-phone handle blows in bearing between described wind wheel and described bearing.
The invention has the beneficial effects as follows: between wind wheel and bearing, be provided with the block piece that the air-flow blocked in cell-phone handle blows in bearing, the air-flow preventing the trachea in handle from producing blows in bearing, the noise produced when reducing dental handpiece work, avoid the damage of foreign body quickening to bearing be mingled with in the gas flow, and after avoiding the grease of Bearing inner to be blown away, accelerate bearing wear damage.
Further, described block piece is the pad being sleeved on position between the corresponding described wind wheel of described rotating shaft and described bearing.
Further, described pad is step pad, and the larger one side of described pad radial dimension touch described wind wheel, and the one side that its radial dimension is less touch described bearing.
Above-mentioned further beneficial effect is: adopt step pad as the block piece be arranged between wind wheel and bearing, to the isolated better effects if of air-flow.
Further, described bearing is ball bearing.
Further, the ball of described bearing adopts hard ceramic material to make.
Above-mentioned further beneficial effect is: bearing adopts ball bearing, and ball is hard ceramic balls, bearing is not easily got rusty damages, can greatly increase the service life, while can reduce the noise produced in bearing running.
