In operation of opening cranium, the general drilling operation of on skull, doing earlier, modes such as boring back reuse milling are opened the skull plate, carry out inner operation.The general volume that requires to bore mobile phone is little, in light weight, reliable operation, heating are little, easy to operate.
Some bore mobile phone and adopt the electric hand drill mode, on the brill mobile phone motor are arranged, because motor has certain power requirement, motor is bigger, so these volume, the weight of boring mobile phones are all bigger.Some also have rechargeable battery except that motor is arranged, more strengthened volume, weight.Influential to the operation operation convenience.
Summary of the invention
The purpose of this utility model provides a kind of medical brill mobile phone, and profile is little, in light weight, easy to operate, helps improving the operation quality.
A kind of medical brill mobile phone described in the utility model, the overcoat that comprises urceolus, is connected with urceolus right part inwall is characterized in that:
Be provided with cover in first in the left part of urceolus, a power shaft cooperates by the inwall location of cover in the clutch shaft bearing and first, and the power shaft left end is that shift fork, right-hand member are first central gears;
Be provided with cover in second in the middle part of urceolus, the left part of second central gear cooperates by the inwall location of cover in second bearing and second;
Be provided with an output shaft in overcoat, this output shaft cooperates with the inwall location of overcoat by the 3rd bearing;
In first, be provided with first order planetary gear mechanism between the cover in the cover and second, its three primary planet pinions and the engagement of first central gear;
In second, be provided with second level planetary gear mechanism between cover and the overcoat, its three secondary planetary gears and the engagement of second central gear;
The left end of second central gear is connected with first planet carrier of first order planetary gear mechanism; The left end of output shaft is connected with second planet carrier of second level planetary gear mechanism, and the right-hand member of output shaft is connected with drill bit.
Described a kind of medical brill mobile phone, its described first order planetary gear mechanism comprise first ring gear that cooperates with the inwall of urceolus, first planet carrier, respectively be connected on first planet carrier by the 4th bearing location and with three primary planet pinions of first ring gear engagement.
Described a kind of medical brill mobile phone, its described second level planetary gear mechanism comprise second ring gear that cooperates with the inwall of urceolus, second planet carrier, respectively be connected on second planet carrier by the 5th bearing location and with three secondary planetary gears of second ring gear engagement.
This utility model adopts flexible axle or alternate manner input power, through two-stage planet deceleration outputting power.The rotating speed height of first order planetary gear mechanism, stressed little, the rotating speed of second level planetary gear mechanism is low, stressed big.The gear ratio of two-stage planet drive mechanism, module thereby do not wait.The module of first planetary gear mechanism is little, gear ratio is big.Module is little, can make that gear is littler, linear velocity is lower, can reduce heating.Gear ratio is big, and rotating speed is reduced rapidly, also can reduce heating.The second planetary gear mechanism second level module is big, and strength of gear teeth height helps stressed.
This utility model is compared with prior art and is had the following advantages:
(1) do not have motor, battery on the brill mobile phone, adopt thin flexible axle input power, brill mobile phone volume, weight reduce greatly.
(2) two-stage planet transmission, gear ratio is big, compact conformation.
(3) all with the rolling bearing supporting, the work heating is little for central gear and planetary gear, and it is hot to avoid boring mobile phone, helps operation technique.
