Abstract
The utility model discloses an electric drill outboard bearing carries support structure relates to mechanical transmission, including the electric drill, motor spindle, electric drill installation cylinder, fix the stomidium on the frame casing, constitute bevel gear pair's gear wheel and pinion, the gear wheel is installed in the frame casing, the pinion revolves in the motor spindle thread end and stretches out the stomidium front end, electric drill installation cylinder adopts location fastening screw to fix in the stomidium, the front end inner wall diameter of stomidium is lighter than rear end inner wall diameter and forms the interior location shaft shoulder, be provided with the bearing in the less front end inner wall of inner wall diameter in the stomidium, the bearing cup joints on the cylindrical surface of spiral bevel gear's rear end, the middle part inner wall of stomidium still overlaps and is equipped with an end ring, the bearing axial is by shells inner wall front end and end ring axial positioning, end ring and the preceding terminal surface laminating of electric drill installation cylindrical. The utility model discloses can improve motor spindle and radially reach axial bearing capacity, prevent the damage that the inside fore bearing of motor caused because of the additional moment simultaneously.
Description
Technical field
The utility model relates to mechanical transmission fields, is the electric drill outrigger shaft carrying supporting structure that a kind of input gear for beveling machine assembles specifically.
Background technique
Small instruments and tools class facility, normal using electric drill as power, the predominant intermolecular forces that when it uses, main bearing is subject to is axial force, radial force is almost negligible, and electric drill superiority be lightweight, volume is little, is convenient to manual hand manipulation etc., but when it is as power, electric machine main shaft bearing, not only bears axial force, bears larger radial force simultaneously.Electric drill anterior main shaft sponson cantilever is longer, and as electric drill particularly with when using for power source, when adopting (spiral) bevel gear drive, its radial component is comparatively serious to the damage of electric drill inside fore bearing in long time continuous working.
Model utility content
The purpose of this utility model is just to provide a kind of electric drill outrigger shaft to carry supporting structure to solve the problem, and it can improve electric machine main shaft radial direction and axial carrying capacity, prevents the damage that motor internal fore bearing causes because of additional moment simultaneously.
The utility model is achieved through the following technical solutions above-mentioned purpose:
Electric drill outrigger shaft carrying supporting structure of the present utility model, comprise electric drill, electric machine main shaft, cylinder installed by electric drill, be fixed on the stomidium on frame housing, form gearwheel and the small gear of bevel gear pair (particularly spiral bevel gear pair), gearwheel is arranged in frame housing, small gear is threaded onto electric machine main shaft threaded end and stretches out stomidium front end, electric drill is installed cylinder and is adopted location fastening screw trip bolt to be fixed in stomidium, wherein, the front inner wall diameter of described stomidium is less than rear end inner diameter and forms the inner position shaft shoulder, in described stomidium, the less front inner wall of inner diameter is provided with bearing, described bearing housing is connected on the cylindrical outer surface of the rear end of helical bevel gear, the middle part inwall of described stomidium is also set with an end ring, described bearing shaft is to by inner walls front end and end ring axially locating, the front-end face that cylinder installed by described end ring and electric drill is fitted.
Further, described bearing is deep groove ball bearing.
The beneficial effects of the utility model are: the utility model alleviates the load of electric drill fore bearing by the bearing in the outside being arranged on helical bevel gear, effectively can improve electric machine main shaft radial direction and axial carrying capacity, prevent the damage that motor internal fore bearing causes because of additional moment simultaneously
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Label declaration in schematic diagram:
1, electric drill; 2, end ring; 3, stomidium; 4, bearing; 5, helical bevel gear; 6, electric machine main shaft; 7, cylinder installed by electric drill; 8, frame housing; 9, gearwheel.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Electric drill outrigger shaft carrying supporting structure of the present utility model, comprise electric drill, electric machine main shaft, cylinder installed by electric drill, be fixed on the stomidium on frame housing 8, form gearwheel and the small gear of bevel gear pair (particularly spiral bevel gear pair), gearwheel 9 is arranged in frame housing 8, small gear is threaded onto electric machine main shaft threaded end and stretches out stomidium front end, electric drill is installed cylinder and is adopted location fastening screw trip bolt to be fixed in stomidium, wherein, the front inner wall diameter of stomidium is less than rear end inner diameter and forms the inner position shaft shoulder, in stomidium, the less front inner wall of inner diameter is provided with bearing, the preferred deep groove ball bearing of this bearing, bearing housing is connected on the cylindrical outer surface of the rear end of helical bevel gear, the middle part inwall of stomidium is also set with an end ring, bearing shaft is to by inner walls front end and end ring axially locating, the front-end face that cylinder installed by end ring and electric drill is fitted.
As shown in Figure 1, the utility model is provided with small gear 5 at electric drill 1 electric machine main shaft 6, the cylindrical outer surface of its rear end combines with bearing 4, bearing 4 external diameter is installed in stomidium 3, bear part small gear 5 to be in operation the axial force produced, it is axially by front boss and end ring 2 axially locating of stomidium 3, and the axial force of electric machine main shaft 6 is born through end ring, motor 1, stomidium 3, radial force is born by stomidium 3 through bearing 4 simultaneously, greatly alleviates the load of electric drill 1 fore bearing.
Through bearing 4 supporting motor main shaft 6 in stomidium 3, its front end is installed small gear 5 and is driven gearwheel to operate.
Above-described embodiment is preferred embodiment of the present utility model; it is not the restriction to technical solutions of the utility model; as long as without the technological scheme that creative work can realize on the basis of above-described embodiment, all should be considered as falling within the scope of the rights protection of the utility model patent.
