Abstract
The invention discloses a sealing structure for a motor box body and an end cover. The sealing structure comprises the motor box body and the end cover. A connecting end with a small inner diameter is arranged at the rear end of the end cover, the diameter of the connecting end is identical to the inner diameter of an opening formed in the motor box body, the connecting end is clamped in the opening of the box body, and the end, in contact of the end cover, of the opening of the motor box body is provided with a circle of chamfered groove. The root of the connecting end of the end cover is further sleeved with a sealing ring used for sealing the gap between the sealing box body and the end cover, the sealing ring is located in the chamfered groove formed in the opening of the motor box body, the motor box body is assembled with the end cover, the sealing ring is extruded and deformed through the chamfered groove, so that sealing is conducted in the radial direction and the axial direction at the same time, sealing is firm, and due to the fact that the sealing ring is used for replacing seal gum for sealing, assembling is convenient and fast, and toxin and pollution are avoided.
Description
Technical field
The present invention relates to motor device field, particularly relate to the hermetically-sealed construction of a kind of motor case body and end cap.
Background technology
The casing of motor and end cap junction need to arrange hermetically-sealed construction and seal, place extraneous water, dust etc. to enter in motor case body and affect motor and normally work, traditional hermetically-sealed construction is that artificial gluing seals on the mating surface of motor case body and end cap, this sealing means gluing trouble is time-consuming, and easily there is holiday, cause poor sealing, and have certain harm for the glue sealed to human body, work in such a case for a long time to the certain harm of health generation of staff.
Summary of the invention
The object of the present invention is to provide a kind of easy to assembly, hermetically-sealed construction of sealing reliable motor case body and end cap.
For reaching this object, the present invention by the following technical solutions:
The hermetically-sealed construction of a kind of motor case body and end cap, comprise motor case body and end cap, described end cap rear end is provided with the little link of internal diameter, the diameter of described link is consistent with the internal diameter of the opening that motor case body is offered, described link is stuck in box opening, the end opens that described motor case body opening contacts with end cap has a circle chamfer groove, the root of described end cap link is also arranged with the sealing ring for the gap between seal case and end cap, and described sealing ring is positioned at the chamfer groove that described motor case body opening is offered.
Further, in described casing, be provided with step, being connected on front side of step of the link of described end cap.
Further, described sealing ring is O RunddichtringO.
Beneficial effect of the present invention is: the hermetically-sealed construction of described motor case body and end cap, link extension little for internal diameter on end cap is snapped in motor case body, and sealing ring in the end sleeve of link, electric motor end cap offers chamfer groove, by motor case body together with end cap assembling, by chamfer groove by sealing ring crimp, thus seal up the gap between motor case body and end cap in radial and axial both direction simultaneously, it is firm to seal, and uses standard seal circle sealing assembling simple.
Accompanying drawing explanation
Fig. 1 is the cutaway view of the hermetically-sealed construction of the motor case body that provides of the specific embodiment of the invention and end cap;
Fig. 2 is the partial enlarged drawing at A place in Fig. 1.
In figure, 1, motor case body; 11, chamfer groove; 12, step 2, end cap; 21, link; 3, O RunddichtringO.
Embodiment
Technical scheme of the present invention is further illustrated by embodiment below in conjunction with accompanying drawing.
As shown in Figure 1, the hermetically-sealed construction of described motor case body and end cap, comprise the motor case body 1 and end cap 2 that offer opening, described end cap 2 comprises the little link 21 of internal diameter that rear end is wholely set, step 12 is provided with in described motor case body 1 opening, the diameter of described link 21 is consistent with the internal diameter of step 12 front end in the opening of motor case body 1, described link 21 is connected to when assembling in the fore-end of the step 12 that motor case body 1 opening is arranged, the end opens contacted with end cap 2 foremost of described motor case body 1 opening has a circle chamfer groove 11, the root of the link 21 of described end cap 2 is also arranged with for the O RunddichtringO 3 of sealed electric-motor casing 1 with end cap 2, when the link 21 of end cap 2 inserts in described motor case body 11 opening, chamfer groove 11 extrudes O RunddichtringO 3, O RunddichtringO 3 extrusion, seal up the gap between motor case body 1 and end cap 2 in radial and axial both direction simultaneously, ensure that motor case body 1 seals firm.
During assembling, only the O RunddichtringO 3 of standard need be set to link 21 root of end cap 2, then the opening of motor case body 1 is inserted on the link 21 of end cap 2, easy to assembly.
Below only describe the present invention with embodiment, but the present invention is not limited to above-mentioned size and outward appearance illustration, more should form any restriction of the present invention.As long as any improvement do the present invention or modification all belong within the protection range of the claims in the present invention opinion.
