Abstract
The invention discloses a speed-up dental handpiece which comprises a machine head, a first transmission shaft, a second transmission shaft and a transitional shaft, wherein one end of the first transmission shaft is connected with the machine head; one end of the transitional shaft is in transmission connection with the first transmission shaft; the other end of the transitional shaft is in transmission connection with the second transmission shaft; an included angle is formed between the first transmission shaft and the second transmission shaft. As the transitional shaft is adopted to connect the two transmission shafts, the transmission between the two transmission shafts can be decomposed effectively, so as to reduce loss of a driving end, and lower the requirements on materials. Therefore, the service life of the speed-up dental handpiece is prolonged to a great extent, and the cost is reduced to a great extent.
Description
Technical field
The present invention relates to medical instruments field, in particular to a kind of speedup dentistry mobile phone.
Background technology
Arranging two transmission shafts at an angle in the curved machine of dentistry mobile phone, two transmission shafts are connected by geartransmission. The diameter of dentistry mobile phone only 10��20mm, the transmitting gear diameter only 3��6mm of its inside, and the transmission shaft of dentistry mobile phone needs bigger rotating speed, therefore transmitting gear is easy wearing detail.
As shown in Figure 1, one transmission shaft of existing dentistry mobile phone arranges conical insert, another transmission shaft arranges internal wheel, and internal wheel is generally straight tooth gear so that the gears meshing contact area of two transmission shafts is little so that act on the moment on the tooth of gear bigger, sliding friction occurs during two geartransmissions, causing material friction serious, the work-ing life of gear is only 1��3 month, seriously affects the work-ing life of dentistry mobile phone.
At present in order to improve the work-ing life of transmission tooth, usually adopt harder material, materially increase the cost of dentistry mobile phone.
Summary of the invention
It is an object of the invention to provide a kind of speedup dentistry mobile phone, at least can one of solve the problem.
For achieving the above object, according to an aspect of the present invention, provide a kind of speedup dentistry mobile phone, comprise head, the first transmission shaft, second driving shaft and transition axis, one end of first transmission shaft is connected with head, one end of transition axis is connected with the first transmission shaft driven, and the other end and the second driving shaft of transition axis are in transmission connection, and the first transmission shaft and second driving shaft have angle. Thus, adopt transition axis to connect two transmission shafts, it is possible to effectively to decompose the transmission action of two transmission shafts, and then reduce the loss to transmission end, reduce the requirement to material.
In some embodiments, the end of the first transmission shaft is provided with gear I, and second driving shaft is provided with gear II, and the two ends of transition axis are respectively equipped with gear III and gear IV, and gear I is meshed with gear III, and gear II and gear IV are meshed. Therefore, adopt geartransmission, two groups of gears can have bigger contact area respectively, the moment of reducing effect on tooth, so reduce gear abrasion, increase work-ing life.
In some embodiments, gear I and gear III are cone gear. Thus two gear external toothings, can closely engage between tooth with tooth, it is achieved pure rolling transmission, effectively reduce gear wear, increase work-ing life.
In some embodiments, gear II is internal wheel, and gear IV is straight tooth gear. Thus two gear internal messing, can closely engage between tooth with tooth, it is achieved pure rolling transmission, effectively reduce gear wear, increase work-ing life.
In some embodiments, also comprise the first housing, elbow and the 2nd housing that connect successively, first housing is connected with head, first transmission shaft, second driving shaft and transition axis are all positioned at the space that the first housing, elbow and the 2nd housing are formed, being provided with support block in elbow, by supporting, block supports transition axis. Thus ensure the firm installation of transition axis in dentistry mobile phone.
The useful effect of the present invention is: speedup dentistry mobile phone adopts transition axis to connect the first transmission shaft and second driving shaft can effectively decompose the transmission action of two transmission shafts, and then reduces the loss to transmission end, reduces the requirement to material. Transition axis and two transmission shafts realize being in transmission connection by gear driving pair, and the setting of two groups of gear driving pairs can make closely to engage between gear, it is achieved pure rolling transmission, effectively reduce gear friction, reduce the requirement to material. The speedup dentistry mobile phone of the present invention has that long service life, cost are low, the simple advantage of structure.
