Description
Technical field
The utility model is related to technical field of motors, is especially a kind of hollow-cup motor casing assembly.
Background technology
Hollow-cup motor belongs to direct current, permanent magnetism, servo small and special electric machine.Energy conservation characteristic of the drag cup motor with protrusion,
Sensitive convenient control characteristic and stable operation characteristic, as efficient energy conversion device, represent sending out for motor
Exhibition direction.And, hollow-cup motor breaches in structure the rotor structure form of conventional motors, uses iron-core-free and turns
Son.
Casing assembly is the requisite part of hollow-cup motor, and its mechanism generally comprises shell and bottom, shell
One end be provided with the through hole that power supply machine rotating shaft is passed.Shell adopts interference fit with bottom, i.e., first uniform in the excircle of bottom
Coat glue, then be pressed into inside the shell with frock, because the bonding plane of two parts is little, adhesive liquid quantity used is limited, bottom with
Cage connection built on the sand, causes bottom ejecting force less than normal, can make product operating abnormal in the case of exceedingly odious.
So, how to develop a kind of bottom and firmly install with shell, and enable what hollow-cup motor normally ran
Hollow-cup motor casing assembly is the direction to be studied of this area staff.
Utility model content
In view of the defect of above-mentioned prior art, the purpose of this utility model is：A kind of hollow-cup motor shell group is provided
Part, bottom is firmly installed with shell, and is enabled to hollow-cup motor and can normally be run.
Technical solution of the present utility model is：Hollow-cup motor casing assembly, including the shell with installing hole with
And be arranged on the bottom of shell bottom, the top of the shell is provided with a perforation being connected with installing hole, the perforation it is interior
Wall is provided with an annular slot, and a sealing ring has been snapped in the draw-in groove；The bottom of the bottom has a disk, the bottom
Outer wall be provided with an annular lug, the bottom inwall of the shell be provided with match with projection and for projection snap in it is annular recessed
Groove.
Further, the outside wall surface of the projection is arc surface, after the projection is snapped in groove, outside the projection
Wall is fitted with the trough wall surface of groove, and the outside wall surface of the bottom is fitted with the internal face of shell.
Further, the bottom of the perforation has chamfering.
Further, the chamfering is circular arc chamfering.
Using hollow-cup motor casing assembly provided by the utility model, its advantage is：Set on the inwall of perforation
There is an annular slot, a sealing ring has been snapped in draw-in groove, because perforation is passed through for the rotating shaft installed in inside the shell, rotating shaft energy
It is enough to contact with sealing ring, improve the sealing effectiveness of housing top end；The bottom of bottom has a disk, and the outer wall of bottom is provided with
One annular lug, the bottom inwall of shell is provided with the annular groove for matching with projection and snapping in for projection, and bottom is pacified with shell
Fill convenient and install firm, fitted seal circle enables to hollow-cup motor using after can normally be run.
Description of the drawings
Fig. 1 is overall structure diagram of the present utility model；
Fig. 2 is decomposing schematic representation of the present utility model.
Shown in figure：1- shells, 11- installing holes, 2- bottoms, 21- disks, 3- perforation, 31- chamferings, 4- draw-in grooves, 5- sealings
Circle, 6- projections, 7- grooves.
Specific embodiment
For it is relatively more directly perceived, be fully understood by the technical solution of the utility model, now just carry out with reference to the utility model accompanying drawing
Nonrestrictive feature description is as follows：
As depicted in figs. 1 and 2, hollow-cup motor casing assembly, including the shell 1 with installing hole 11 and setting outside
The bottom 2 of the bottom of shell 1, the top of shell 1 is provided with a perforation 3 being connected with installing hole 11, and the inwall of perforation 3 is provided with a ring
Shape draw-in groove 4, has snapped in a sealing ring 5 in draw-in groove 4；The bottom of bottom 2 has a disk 21, and the outer wall of bottom 2 is provided with a ring
Shape projection 6, the bottom inwall of shell 1 is provided with the annular groove 7 for matching with projection 6 and snapping in for projection 6.
The connection of bottom 2 and shell 1 for convenience, also for being easy to the later stage to dismantle, the outside wall surface of projection 6 is arc surface,
Projection 6 is elastomer block, and after projection 6 is snapped in groove 7, the outside wall surface of projection 6 is fitted with the trough wall surface of groove 7, outside bottom 2
Wall is fitted with the internal face of shell 1.
The bottom of perforation 3 has chamfering 31.Preferably, chamfering 31 is circular arc chamfering 31, is easily installed in turning in shell 1
Axle is passed through.
Hollow-cup motor casing assembly provided by the utility model, the inwall of perforation 3 is provided with an annular slot 4, blocks
A sealing ring 5 has been snapped in groove 4, because perforation 3 is passed through for the rotating shaft (not shown) in shell 1, rotating shaft energy
It is enough to contact with sealing ring 5, improve the sealing effectiveness on the top of shell 1；The bottom of bottom 2 has a disk 21, the outer wall of bottom 2
An annular lug 6 is provided with, the bottom inwall of shell 1 is provided with the annular groove 7 for matching with projection 6 and snapping in for projection 6, bottom
Lid 2 is with the install convenient of shell 1 and installs firm, and enabling to hollow-cup motor after the use of fitted seal circle 5 can normally run.
Certainly, these are only preferred embodiment of the present utility model, it is non-therefore limit to patent of the present utility model
Simple modification and the equivalent structure change for it of scope, all utilization the utility model specifications and schema content institute, all should wrap in the same manner
It is contained within scope of patent protection of the present utility model.
