Description
Technical field
This utility model is related to technical field of motors, more particularly, to a kind of rear end cap waterproof construction.
Background technology
If the moisture for motor internal being flowed into by cooling air is collected at motor internal, be easily damaged the zero of motor internal
Part, in consideration of it, need moisture is timely derived motor, to ensure the stability and reliability of motor work.
Utility model content
The purpose of this utility model is to provide a kind of rear end cap waterproof construction, and which can will flow into motor by cooling air
Internal moisture derives motor by rear end cap, so as to the parts of effective protection motor internal are against damages, it is ensured that motor work
The stability and reliability of work.
For solving above-mentioned technical problem, embodiment of the present utility model provides a kind of rear end cap waterproof construction, and which wraps
Rear end cap is included, there is rear end cap centrally arranged axis hole, rear end cap to be provided with the bearing mounting groove around axis hole, bearing mounting groove
Diapire is provided with concave shape drainage channel, and concave shape drainage channel is provided with the perforate that water is discharged motor.
Compared with prior art, the rear end cap waterproof construction that this utility model is provided is by drainage channel by water effective
Derivation motor, and the water guide structure does not affect the installation of bearing arrangement.
Further, concave shape drainage channel is in cross-like groove structure.
Further, perforate is provided with four in concave shape drainage channel.
Further, bearing mounting groove is provided with the annular recess communicated with cross-like groove structure around axis hole.
Further, concave shape drainage channel and the perforate being arranged at set by concave shape drainage channel are noted with rear end cap one
Molded.
Description of the drawings
Fig. 1 is rear end cap waterproof construction schematic diagram.
Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that this utility model is realized are easy to understand, under
Face in conjunction with specific embodiments, is expanded on further this utility model.
First embodiment of the present utility model provides a kind of rear end cap waterproof construction, shown in Figure 1, after which includes
There is centrally arranged axis hole, rear end cap to be provided with the bearing mounting groove 1 around axis hole, bearing mounting groove bottom for end cap E, rear end cap
Wall is provided with concave shape drainage channel 2, when water is then led further at the little concavity drainage channel in bearing mounting groove position,
And concave shape drainage channel is provided with the perforate 3 that water is discharged motor.
From the discussion above it is seen that, the moisture in motor can be drained by the rear end cap waterproof construction by perforate,
Avoid moisture from being collected in motor internal and damage motor internal parts, as bottom surface and the concave shape of bearing mounting groove are arranged
The work surface of aquaporin is not at approximately the same plane such that it is able to avoid discharge structure for the isostructural interference of bearing.
It is noted that concave shape drainage channel herein is in cross-like groove structure, that is to say, that install in bearing
On the annular working face that groove bottom land is located, four sub- draining recesses of distribution collectively form a cross-like groove structure and carry out
Draining, is provided with a perforate 3 in per individual sub- draining recess, so as to constitute the concave shape row with four perforates
Aquaporin, branch of the sub- draining recess as cross-like groove structure, can collect the hydrops of adjacent position, drainage efficiency respectively
More efficient.
In addition, in cross-like groove structure, the phase in the side wall of sub- draining recess and the commutation work face of bearing mounting groove
Ortho position installs and is equipped with circular arc chamfering (or directly chamfering), and which is more efficient for the guiding shunting action of water.
Wherein, bearing mounting groove is provided with the annular recess communicated with cross-like groove structure around axis hole, and high annular is recessed
Portion surround axis hole, as work surface of the annular recess with cross-like groove structure is in approximately the same plane, such that it is able to be formed
The effect of the sub- draining recess of insertion four so that between each branch of cross-like groove structure can mutual conduction and be beneficial to
Draining, it should be noted that " work surface of cross-like groove structure " referred to herein refers to the bottom land table of sub- draining recess
Face.
In the present embodiment, concave shape drainage channel and the perforate being arranged at set by concave shape drainage channel and rear end cap
Integrated injection molding,, for the rear end cap that is made using materials such as plastics, cost and quality are more controllable for this.
Second embodiment of the present utility model provides a kind of rear end cap waterproof construction, and which is used as to first embodiment
Further improvement, the improvement is that, the work surface of concave shape drainage channel 2 has the incline structure towards perforate.
Specifically, the four sub- draining recesses generally middle position in cross-like groove structure is provided with for by water
Be diverted to the perforate of outside motor, and as each sub- draining recess work surface by the way of certain slope by water
Tapping is come together in, as a kind of selection, the tapered structure of the work surface of sub- draining recess, and perforate is then located at cone structure
Bottom, this structure are conducive to water to be quickly oriented to perforate by the incline structure while flowing to sub- draining recess, draining
Efficiency is further enhanced, the contour structures for affecting rear end cap for avoiding the incline structure gradient excessive, this sub- draining recess
Work plane inclination less be advisable, moreover, the work surface of sub- draining recess can arrange texture structure, lines knot
Structure radial arrangement along perforate, which is become apparent from for water guiding action, or, set in the work surface of sub- draining recess
Ceramic structure layer is put, effectively can be reduced the hydropexic time.
It will be understood by those skilled in the art that the respective embodiments described above are to realize of the present utility model being embodied as
Example, and in actual applications, can to which, various changes can be made in the form and details, without departing from spirit of the present utility model
And scope.
