Abstract
The utility model provides a sealing device of a motor cooling water channel, which comprises a motor casing body and an end cover matching with the casing body. At least two through holes penetrating through two sides of the casing body are arranged on the casing body; a groove for communicating the two through holes is arranged on the lateral wall between two adjacent through holes; a boss matching with the groove is arranged on the end cover; and a sealing part for sealing the groove is arranged between the boss and the groove. The sealing device is convenient to be installed and not easy to leak water.
Description
Technical field
The motor that the utility model relates to a kind of sealing device of motor cooling water channel and has the sealing device.
Background technology
Motor can produce loss when operation at present, and the heat energy that loss produces raises the temperature of each parts of motor and influence the safe operation of motor,, be equipped with cooling water channel on the therefore general electric machine casing simultaneously because but the restriction of temperature also can make motor shorten the running time under certain power.As depicted in figs. 1 and 2, electric machine casing 4a is provided with at least two through holes that connect described housing both sides, sidewall between two adjacent through holes is provided with the groove 3a that is communicated with two through holes, the sealing device of cooling water channel comprises sealing gasket 2a that is covered on the groove and the end cap 1a that is pressed on the sealing gasket, be equipped with corresponding screwed hole on electric machine casing 4a, sealing gasket 2a and the end cap 1a, make electric machine casing 4a, sealing gasket 2a and end cap 1a be assembled into one by bolt, make the salable above-mentioned groove 3a of sealing gasket 2a.But because sealing gasket 2a adopts silastic material, softer, can't guarantee the perforate precision on the sealing gasket 2a, during perforate precision on can't guaranteeing sealing gasket 2a, hole on the sealing gasket 2a is not easy to aim at the screwed hole on electric machine casing 5a and the end cap 1a, damages sealing gasket 2a when mounted easily, and when end cap 1a compresses sealing gasket 2a, the situation that occurs sealing gasket 2a excessive deformation easily and occur leaking causes motor to be burnt.
The utility model content
The utility model is not easy to aim at the screwed hole on electric machine casing and the end cap for the hole that solves on the prior art sealing gasket, damage sealing gasket when mounted easily, and when end cap compresses sealing gasket, the problem that occurs the sealing gasket excessive deformation easily and occur leaking provides a kind of easy installation and the sealing device of the motor cooling water channel that is not easy to leak and the motor with sealing device.
The utility model provides a kind of sealing device of motor cooling water channel, comprise electric machine casing and the end cap that cooperates with housing, described housing is provided with at least two through holes that connect described housing both sides, sidewall between two adjacent through holes is provided with the groove that is communicated with two through holes, described end cap is provided with the boss with described groove fit, also is provided with the seal that is used to seal described groove between described boss and the groove.
The utility model also provides a kind of motor, comprises above-mentioned sealing device.
The utility model compared with prior art, by on end cap, being provided with the boss with described groove fit, the boss sectional area ratio is bigger, easily with housing on groove alignment, convenient installation is provided with seal between groove and boss, in the gap between sealed groove and the boss, also just cooling water channel is sealed, and good airproof performance, be not easy to leak.

Embodiment
Clearer for technical problem, technical scheme and beneficial effect that the utility model is solved, 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 explanation the utility model, and be not used in qualification the utility model.
As Fig. 3, Fig. 4, Fig. 5 and shown in Figure 6, according to a kind of execution mode of the present utility model, the utility model provides a kind of sealing device of motor cooling water channel, comprise electric machine casing 1 and the end cap 2 that cooperates with electric machine casing 1, described housing 1 is provided with at least two through holes 3 that connect described housing 1 both sides, sidewall between two adjacent through holes 3 is provided with the groove 4 that is communicated with two through holes 3, described end cap 2 is provided with the boss 5 that cooperates with described groove 4, also is provided with the seal that is used to seal described groove 4 between described boss 5 and the groove 4.
As further improvement, be matched in clearance between described groove 4 and the boss 5, described boss 5 is inserted in the described groove 4 easily.Described boss 5 is one-body molded with described end cap 2, and boss 5 also can be fixed on the end cap 2 by the mode of welding certainly, but with described end cap 2 integrated boss 5, adding the precision that can better guarantee boss 5 man-hour, make that boss 5 is easier to be cooperated with groove 4.
As further improvement, the sealing gasket that described seal also adapts with boss 5 shapes, but because described seal between the gap of groove 4 and boss 5, forms interference fit between the inwall of the easier and groove 4 of the cylindrical of sealing ring 6, good airproof performance is not easy to leak.Under the preferable case: described seal is the sealing ring 6 that adapts with boss 5 shapes, and described sealing ring 6 is enclosed within on the described boss 5.
As further improvement, described groove 4 is crisscross arranged both sides at described electric machine casing 1 successively described through hole 3 is connected into the water channel of a S shape, promptly the groove 4 on electric machine casing 1 one sides is communicated with adjacent two through holes, the delivery port of first through hole is communicated with the water inlet of second through hole, and on electric machine casing 1 opposite side, be communicated with the water inlet of the 3rd through hole by the delivery port of another groove 4 with second through hole, therefore on electric machine casing 1, form the cooling water channel of axial round about manner, this structure processing technology is simple, cooling water makes the better effects if of heat radiation more near the heating position of motor.
The utility model also provides a kind of motor that comprises above-mentioned sealing device.
The assembling of this motor is as follows: be equipped with screwed hole on electric machine casing 1 and the end cap 2, on the boss 5 of end cap 2 sealing ring 6 is housed, boss 5 is aimed at the groove 4 of electric machine casing 1 then, boss 5 is inserted in the described groove 4, by bolt end cap 2 is fixed on the electric machine casing 1, the cylindrical interference fit of the inwall of described groove 4 and sealing ring 6, good airproof performance, the water in the cooling water channel can not spill.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
