Abstract
The utility model discloses a waterproof motor, which comprises a stator, a rotor and a shell, wherein the rotor is arranged in the shell through a rotating shaft, two ends of the shell are provided with a front end cover and a rear end cover respectively, a labyrinth type seal is provided between the front end cover and the shell, the front end cover is provided with a press cover, the press cover is sleeved on the rotating shaft and hermetically connected with the rotating shaft through a sealing ring, and the rear end cover is hermetically connected with the shell and covers on the periphery of the rear end part of the rotating shaft. The waterproof motor disclosed by the utility model has good sealing and insulating performance, and high heat resistance, thereby being very suitable for being used in humid severe environments.
Description
Technical field
The utility model relates to a kind of motor, especially relates to a kind of motor with water-proof function.
Background technology
Because the operational environment of motor is very abominable, under wet environment, common waterproof machine does not satisfy needs at all.The rear end of common electric machine is provided with radiator fan, ventilates and forced heat radiation for motor provides, and still, water is easy to enter in the bore of stator from the fan spindle nose, causes motor to damage; Moreover the front end spindle nose of motor because hermetically-sealed construction is the sealing of conventional seals circle, also is easy to into water.
The utility model content
The utility model is in order to overcome the deficiencies in the prior art, and a kind of motor of simple in structure, good water-proof effect is provided.
To achieve these goals, the utility model is by the following technical solutions: a kind of waterproof machine, comprise stator, rotor and housing, rotor is located in the housing by rotating shaft, the two ends of housing are respectively equipped with front end housing and rear end cap, are labyrinth sealing between described front end housing and the housing, and front end housing is provided with gland, gland is sheathed in the rotating shaft, and and rotating shaft between be tightly connected by sealing ring; Described rear end cap is connected with housing seal, and rear end cap covers in the periphery of rotating shaft rearward end; The sidewall of described housing is provided with terminal box, and this terminal box comprises box body, end cap, cable tube and seal cover, and the front end of end cap is provided with recess, and seal cover is located at the front end of end cap, and and the recess of end cap between be provided with packing ring.
As preferably, the inwall of described rotor is coated with at least 2 layers of insulation enamelled coating
As preferably, described packing ring is asbestos pad, and the thickness of this asbestos pad is 1mm.
The utlity model has following advantage: this motor seal property is good, and good insulation preformance, thermal endurance height use in the adverse circumstances of very suitable humidity.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make those skilled in the art person better understand the utility model scheme, below in conjunction with the accompanying drawing among the utility model embodiment, technical scheme among the utility model embodiment is carried out clear, complete description, obviously, described embodiment only is a part of embodiment of the present utility model, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all should belong to the scope of the utility model protection.
As shown in Figure 1, a kind of waterproof machine, comprise stator, rotor 1 and housing 2, rotor 1 is located in the housing 2 by rotating shaft 3, the two ends of housing 2 are respectively equipped with front end housing 11 and rear end cap 12, adopt labyrinth sealing between described front end housing 11 and the housing 2, and front end housing 11 is provided with gland 4, gland 4 is sheathed in the rotating shaft 3, and and rotating shaft between be tightly connected by sealing ring 5; Rear end cap 12 is tightly connected with housing 2, and rear end cap 12 covers in the periphery of rotating shaft 3 rearward end; The inwall of rotor 1 applies the insulation enamelled coating that haves three layers, and has greatly improved insulation property and the heat-proof quality of motor.The sidewall of housing 2 is provided with terminal box, this terminal box comprises box body 61, end cap 63, cable tube 64 and seal cover 62, and the front end of end cap 63 is provided with recess, and seal cover 62 is located at the front end of end cap 63, and and being provided with packing ring 9 between the recess of end cap 63, it is the asbestos pad of 1mm that packing ring 9 adopts thickness.This motor is wrapped in the spindle nose of the rotating shaft of rotor in the rear end cap fully, and has removed fan, and rear end cap has just sealed fully like this, simultaneously, applies 3 layers of insulation enamelled coating in rotor, has improved thermal diffusivity and insulating properties.Also improve at the terminal box position, and traditional terminal box also is easy to into water, wiring good seal performance after improving.The utility model is simple in structure, and water resistance is good, and thermal endurance and insulating properties are high, use in the adverse circumstances of very suitable humidity.
