Description
Technical field
The utility model belongs to steering gear apparatus technical field, relates in particular to a kind of light steering gear.
Background technology
Steering gear is the vitals of direct current machine, and effect is that the direct current being passed through on brush is converted to the alternating current in winding or the alternating electromotive force in winding is converted to the direct electromotive force. on brush end.Principle is, when coil is by after electric current, can be under the effect of permanent magnet, by attracting and repulsive force rotation, in the time that it forwards to magnet balance, the contact originally leading on the more corresponding commutator of line of electricity is just separated with brush, and brush is connected to and meets that produce motive force and organize on contact corresponding to coil, so ceaselessly repeat down, DC motor has just been turned over.The steering gear existing at present exists unreasonable structure, cause processing inconvenient, and whole steering gear weight is heavier, adds and wastes material man-hour, wastes energy when use, thereby has shortened its service time.
Summary of the invention
The purpose of this utility model is to solve above-described technical problem, provides a kind of rational in infrastructure, is convenient to processing and the lighter light steering gear of weight, and its technical scheme is as follows:
A kind of light steering gear, it is characterized in that, described light steering gear comprises cylinder-shaped body, in the axial direction of described cylinder-shaped body, offer through hole, on the lateral wall of described cylinder-shaped body, evenly offer some linear groove, in described linear groove, be filled with insulating barrier, described insulating barrier is embedded in linear groove and the upper surface of insulating barrier is positioned at linear groove, and the spacing between the upper surface of described insulating barrier and cylinder-shaped body lateral wall is 0.5-1mm; The upper surface of described cylinder-shaped body is connected with steering head, in the axial direction of steering head, offer axis hole, described axis hole communicates with through hole, described shaft hole diameter is less than the diameter of through hole, the sidewall equal intervals of described steering head is provided with direction turning piece, between adjacent direction turning piece, be provided with insulating trip, described insulating trip extends to lower surface from the upper surface of direction turning piece by side and communicates with insulating barrier.
The light steering gear that the utility model provides, when in use, offers through hole in the axial direction of described cylinder-shaped body, in the axial direction of steering head, offers axis hole, and described axis hole is identical with through hole, and described shaft hole diameter is less than the diameter of through hole.Can make steering gear more convenient in processing by through hole and axis hole.Steering gear, in processing, can well be played supporting and location effect with backstay by through hole and axis hole, makes to process convenient and accurate.On the lateral wall of described cylinder-shaped body, evenly offer some linear groove, in described linear groove, be filled with insulating barrier, described insulating barrier is embedded in linear groove and the upper surface of insulating barrier is positioned at linear groove, and the spacing between upper surface and the cylindrical outer side wall of described insulating barrier is 0.5-1mm; Because insulating barrier is that depression is arranged on whole cylinder-shaped body, so make the insulating material use in insulating barrier less, reducing the weight that has also reduced steering gear in the situation that material being used.
The beneficial effects of the utility model are: rational in infrastructure, be convenient to processing and weight lighter.
Brief description of the drawings
Fig. 1 is schematic diagram of the present utility model.
Embodiment
Illustrate embodiment below in conjunction with Fig. 1:
As shown in Figure 1, a kind of light steering gear, described light steering gear comprises cylinder-shaped body 1, in the axial direction of described cylinder-shaped body 1, offer through hole 2, on the lateral wall of described cylinder-shaped body 1, evenly offer some linear groove 3, in described linear groove 3, be filled with insulating barrier 4, described insulating barrier 4 is embedded in linear groove 3 and the upper surface of insulating barrier 4 is positioned at linear groove 3, and the spacing between the upper surface of described insulating barrier 4 and cylinder-shaped body 1 lateral wall is 0.5-1mm; The upper surface of described cylinder-shaped body 1 is connected with steering head 5, in the axial direction of steering head 5, offer axis hole 6, described axis hole 6 communicates with through hole 2, described axis hole 6 diameters are less than the diameter of through hole 2, the sidewall equal intervals of described steering head 5 is provided with direction turning piece 7, between adjacent direction turning piece 7, be provided with insulating trip 8, described insulating trip 8 extends to lower surface from the upper surface of direction turning piece 7 by side and communicates with insulating barrier 4.
The light steering gear that the utility model provides, when in use, offers through hole in the axial direction of described cylinder-shaped body, in the axial direction of steering head, offers axis hole, and described axis hole is identical with through hole, and described shaft hole diameter is less than the diameter of through hole.Can make steering gear more convenient in processing by through hole and axis hole.Steering gear, in processing, can well be played supporting and location effect with backstay by through hole and axis hole, makes to process convenient and accurate.On the lateral wall of described cylinder-shaped body, evenly offer some linear groove, in described linear groove, be filled with insulating barrier, described insulating barrier is embedded in linear groove and the upper surface of insulating barrier is positioned at linear groove, and the spacing between upper surface and the cylindrical outer side wall of described insulating barrier is 0.5-1mm; Because insulating barrier is that depression is arranged on whole cylinder-shaped body, so make the insulating material use in insulating barrier less, reducing the weight that has also reduced steering gear in the situation that material being used.
