Abstract

The utility model discloses a motor casing which comprises a shell, and a front cover and a back cover which are connected to both ends of the shell, wherein the lowest point of the shell is provided with a drainage hole, and a one-way drainage plug is inserted in the drainage hole; the one-way drainage plug is provided with a waterproof cover and a plunger body, and a plurality of maze sheets are distributed on the plunger body. The lowest point of the shell is provided with the drainage hole, and the one-way drainage plug is inserted in the drainage hole; therefore, some condensed water can be generated inside the motor and discharged out of the motor casing through the drainage hole; and due to the action of the one-way drainage plug, outside rain water or liquid can be prevented from flowing into the motor casing through the drainage hole, thereby ensuring the safety of the motor.

Description

A kind of motor case

Technical field

The utility model relates to a kind of parts of motor, relates to a kind of motor case that has from drain function specifically.

Background technology

Prior motor; Usually form by casing, rotor assembly and stator module; The big portion of rotor assembly and stator module by the front and back ends lid may enclose in housing; In order to prevent that extraneous rainwater or other liquid from infiltrating in the motor case, is provided with sealing ring in the junction of housing and forward and backward end cap usually.Infiltrate motor internal though can prevent extraneous rainwater or other liquid like this; But when the environment occurrence temperature at motor place changed, as when hot environment becomes low temperature environment, motor internal can produce some condensed waters; Because the junction of housing and forward and backward end cap has excellent sealing performance; Cause this part condensed water to evaporate, can make motor internal lure erosion after long-time, even might cause the fault of motor from motor internal.

The utility model content

For overcoming above-mentioned defective, the utility model aims to provide a kind of extraneous rainwater or other liquid of can preventing and infiltrates motor internal, can drain the motor case of condensed water in the motor simultaneously again fast.

For achieving the above object; The technical scheme that the utility model adopts is: a kind of motor case; Comprise a housing and the protecgulum and the bonnet that are connected in housing two ends, the minimum point of said housing has an osculum, is plugged with a single slope drainage plug on the said osculum.

Said single slope drainage plug has a waterproof cover and stick harness body, is distributed with several labyrinth sheets on the said stick harness body.

Adopted the motor case of the utility model, owing to be provided with an osculum in the minimum point of housing, and on osculum, be plugged with a single slope drainage plug; On the one hand; Can make motor internal can produce some condensed waters and discharge motor case through this osculum, on the other hand, because the effect of single slope drainage plug; Can avoid extraneous rainwater or liquid to flow in the motor case, guarantee the fail safe of motor through osculum.

Description of drawings

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the local structure for amplifying sketch map of Fig. 1.

Among the figure: 1-housing, 2-protecgulum, 3-bonnet, 4-osculum, 5-single slope drainage plug, 6-waterproof cover, 7-stick harness body, 8-labyrinth sheet.

Embodiment

As shown in Figure 1; The utility model discloses a kind of motor case, comprise a housing 1 and protecgulum that is connected in housing 1 two ends 2 and bonnet 3, the stator module of motor and the part of rotor assembly are sealed in the casing that housing 1, protecgulum 2 and bonnet 3 surround; In sum; With the structure basically identical of prior motor casing, the innovative point of the utility model is that mainly the minimum point of said housing 1 has an osculum 4, is plugged with a single slope drainage plug 5 on the said osculum 4.When motor is vertical mounting means, because of the minimum point of motor case not on housing 1, at this moment, said osculum 4 must be arranged on the minimum point of bonnet 3, and is same, also must be plugged with a single slope drainage plug 5 on the said osculum 4.Like this, the condensed water in the motor case converges to the minimum point of interior, and through the gap outflow motor casing between osculum 4 and the single slope drainage plug 5, extraneous rainwater or other liquid then can't get in the motor case.

The concrete structure of said single slope drainage plug 5 is: waterproof cover 6 and the stick harness body 7 that is connected above that are distributed with several labyrinth sheets 8 on the said stick harness body 7.Usually labyrinth sheet 8 is vertical with stick harness body 7, and labyrinth sheet 8 has some breaches on circumference, and the position of the breach on adjacent every layer or the every group of labyrinth sheet 8 is not on same perspective plane.

Claims

1. motor case; Comprise a housing (1) and be connected in the protecgulum (2) and the bonnet (3) of housing (1) two end; The minimum point that it is characterized in that said housing (1) has an osculum (4); Be plugged with a single slope drainage plug (5) on the said osculum (4), said single slope drainage plug (5) has a waterproof cover (6) and stick harness body (7), is distributed with several labyrinth sheets (8) on the said stick harness body (7).
