Technical field
The utility model relates to transmission art field, particularly relates to a kind of miniature gears case and shell thereof.
Background technique
The use of the miniature gears case that, reduction speed ratio little for volume is high is more and more extensive, such as electronic lock, communication apparatus, precision instrument, medical apparatus, Smart Home etc.Along with automation, intelligentized development, require more and more higher to the microminiaturization of retarder.Existing miniature gears case is connected and fixed on a client mainly through screw or buckle, along with the reduction that miniature gears casing is long-pending, for screw connection or the space also deficiency for snapping on gearbox-case, and when assembling, installation time is long, needs cost of labor higher.
Model utility content
The purpose of this utility model is to provide miniature gears case and shell thereof, and be intended to solve when miniature gears casing is long-pending less in prior art, the mode that miniature gears case cannot use screw to connect carries out installing the problem of fixing.
For solving the problems of the technologies described above, the technical solution of the utility model is: provide a kind of miniature gears case shell, comprise the outer cover body of hollow, described outer cover body has input end and output terminal, described output terminal is the loading end of output shaft, described outer cover body sidewall is provided with the plane of orientation that at least one extends to described output end face, and described plane of orientation carries out circumference rotation for limiting described outer cover body.
Alternatively, the end face circumference of described output terminal is provided with guiding fillet.
Alternatively, described plane of orientation is multiple, and multiple described plane of orientation is uniformly distributed on described outer cover body sidewall.
The utility model additionally provides a kind of miniature gears case, comprising miniature gears case shell, being located at the gearing in described miniature gears case shell and being located at described miniature gears case shell end face for driving the motor of described gearing, described miniature gears case shell is above-mentioned miniature gears case shell.
Alternatively, described motor is provided with axial limit structure away from the end face of described miniature gears case shell.
In the utility model, miniature gears case shell is provided with to coordinate with client computer and carries out the spacing plane of orientation of circumference, thus the fixing screw that no longer relies on of the installation of miniature gears case has been come, especially when miniature gears casing is long-pending less, this Placement is simpler, assembling of being more convenient for.

Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
It should be noted that, when element is called as " being fixed on " or " being arranged at " another element, it can directly on another element or may there is centering elements simultaneously.When an element is called as " being connected to " another element, it can be directly connected to another element or may there is centering elements simultaneously.
Also it should be noted that, the orientation term such as left and right, upper and lower in the present embodiment, is only relative concept or be reference with the normal operating condition of product each other, and should not be regarded as have restrictive.
With reference to Fig. 1, a kind of miniature gears case shell that the utility model embodiment provides, it comprises the outer cover body 10 of hollow, and outer cover body 10 has input end 11 and output terminal 12, and outer cover body 10 sidewall is provided with the plane of orientation 13 that at least one extends to output terminal 12.With reference to Fig. 2, outer cover body 10, motor 50 and the gearing (not shown) be placed in outer cover body 10 are assembled into and are integrally formed miniature gears case 20.Gearing has output shaft 30, and output shaft 30 is stretched out by the output terminal 12 of outer cover body 10, that is to say that the output terminal 12 of outer cover body 10 is the loading end of output shaft 30.When miniature gears case 20 is applied in each client computer, miniature gears case 20 and client computer are assembled.As shown in Figure 2, show the portions of client machine structure 40 of assembling with miniature gears case 20, client architecture 40 has spacing end face 41, is circumferentially with mounting plane 42 at spacing end face 41.When miniature gears case 20 assembles with client architecture 40, the plane of orientation 13 on miniature gears case shell is fitted with mounting plane 42, and output terminal 12 end face of miniature gears case shell is resisted against on spacing end face 41 simultaneously.
In the present embodiment, due to the mounting structure adopting plane of orientation 13 and mounting plane 42 to fit, limit the rotation of miniature gears case 20 in the circumferential, do not need to adopt screw fixation method again, especially, when miniature gears case 20 small volume, this Placement is more convenient for assembling.
Further, the end face circumference of output terminal 12 is provided with the rounding 14 with leading role.When miniature gears case 20 assembles with client architecture 40, by the rounding off of rounding 14, miniature gears case 20 can be made steadily, to be swimmingly in place; And the stress that the design of rounding 14 it also avoid due to assembling or power unit work generation is concentrated, and improves the intensity of outer cover body 10, meanwhile, improves the working life of miniature gears case 20.
Further, plane of orientation 13 is multiple, and multiple plane of orientation 13 is uniformly distributed on outer cover body 10 sidewall.In the present embodiment, plane of orientation 13 is preferably four.Certainly, also according to actual conditions, the plane of orientation 13 of other quantity can be set.Accordingly, in client architecture 40, mounting plane 42 is identical with plane of orientation 13 quantity, thus ensures that, when assembling, plane of orientation 13 can be fitted by one_to_one corresponding with mounting plane 42, thus reaches good circumferential position-limiting action.
The utility model additionally provides a kind of miniature gears case 20, and miniature gears case 20 comprises miniature gears case shell, be placed in gearing in miniature gears case shell and miniature gears case shell end face for driving the motor 50 of described gearing.Wherein, miniature gears case shell is above-mentioned miniature gears case shell.The spacing plane of orientation 13 of circumference is carried out because miniature gears case shell is provided with to coordinate with client architecture 40, thus the fixing screw that no longer relies on of the installation of miniature gears case 20 has been come, special in miniature gears case 20 small volume, this Placement is simpler, assembling of being more convenient for.
Further, in the present embodiment, motor 50 is provided with axial limit structure 60 away from the end face of miniature gears case shell.When miniature gears case 20 is applied in each client computer, axial limit structure 60 is fixed on (not shown client-part) in each client computer, thus miniature gears case 20 can not be moved in the axial direction.Certainly, when being provided with the containing space mated with miniature gears case 20 boundary dimension in client computer, herein also can omitted axial limit structure 60, miniature gears case 20 is placed in containing space just, axially irremovable.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
