Abstract
The utility model discloses a motor used for a cooling tower. The motor comprises a rotor, a rotating shaft and a casing. Two ends of the casing are provided with a front end cover and a rear end cover respectively, wherein the rear end cover is provided with a shaft hole penetrated by the rotating shaft. A fan cover is covered at the periphery of the rear end cover. The inner side of the rear end cover is provided with a bearing chamber for installing a bearing. A waterproof cover which is provided with a cone-shaped extending hole penetrated by the rotating shaft is arranged between the rear end cove and the fan cover; the cone-shaped extending hole extends into the shaft hole of the rear end cover; and an end portion of the cone-shaped extending hole contacts with the rear end surface of the bearing; a side wall of the casing is provided with a junction box; the junction box comprises a box body, an end cover, a cable pipe and a sealing cover; the front end of the end cover is provided with a recessed portion; the sealing cover is arranged at the front end of the end cover; and a gasket is arranged between the sealing cover and the recessed portion of the end cover. According to the motor used for the cooling tower of the utility model, the rotating shaft is in tight fit with the cone-shaped extending hole of the rear end cover, such that the motor has excellent sealing performance and is very suitable for being used for the cooling tower; and the junction box is of a waterproof structure, such that short-circuit accidents will not occur, and therefore, the motor is safe in usage.
Description
Technical field
The utility model relates to a kind of motor for cooling tower.
Background technology
Motor on the cooling tower because its special operational environment need have the anti-function of drenching of waterproof preferably, also will stand being exposed to the sun of the sun; And existing cooling tower motor special, has certain anti-pouring function in order to deal with rainy bad weather such as grade, but, even when not raining, the wet environment of cooling tower, the terminal box of motor is slowly made moist, particularly click the rear end cap place, moisture is the easiest to be entered, and long-play gets off, damage motor easily, cause the accident.
The utility model content
The utility model provides a kind of simple in structure in order to overcome the deficiencies in the prior art, good water-proof effect, the cooling tower motor special of long service life.
To achieve these goals, the utility model is by the following technical solutions: a kind of motor for cooling tower, comprise rotor, rotating shaft and shell, the two ends of shell are respectively equipped with front end housing and rear end cap, rear end cap is provided with the axis hole that passes for rotating shaft, the periphery of rear end cap is covered with a fan housing, the inboard of rear end cap is provided with for bearings mounted bearing chamber, be provided with this bucker of a bucker between described rear end cap and the fan housing and be provided with the taper elongated hole that passes for rotating shaft, this taper elongated hole puts in the axis hole of rear end cap, and taper elongated hole end contacts with the rear end face of bearing; The sidewall of described shell 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, be provided with a waveform packing ring between the rear end face of described rear end cap and bearing.
The front end of described bearing is provided with a sealing ring.
Described front end housing and rotating shaft contact position are provided with sealing gasket.
Further again, the junction of described front end housing, rear end cap and shell is coated with sealant layer.
Or be coated with anticorrosive coat on the described shell.
In sum, the utility model has following advantage: cooperate between the taper elongated hole of rotating shaft of the present utility model and rear end cap closely, and good seal performance, very suitable cooling tower uses; The terminal box waterproof construction arranges, and the accident that can not be short-circuited is used safety.
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, the technical scheme among the utility model embodiment is carried out clear, complete description.
As shown in Figure 1, a kind of motor for cooling tower, comprise rotor 2, rotating shaft 3 and shell 1, the two ends of shell 1 are respectively equipped with front end housing 11 and rear end cap 12, rear end cap 12 is provided with the axis hole 4 that passes for rotating shaft 3, the periphery of rear end cap 12 is covered with a fan housing 5, the inboard of rear end cap 12 is provided with for the bearing chamber that bearing 7 is installed, be provided with a bucker 6 between described rear end cap 12 and the fan housing 5, this bucker is provided with the taper elongated hole 61 that passes for rotating shaft 3, this taper elongated hole 61 puts in the axis hole 4 of rear end cap, and taper elongated hole 61 ends contact with the rear end face of bearing 7.By the taper elongated hole is set, be conducive to the installation of rotating shaft, adopt the mode of interference fit to fasten firmly between rotating shaft and the taper elongated hole simultaneously, be difficult for water inlet; The sidewall of described shell 1 is provided with terminal box, this terminal box comprises box body 61, end cap 63, cable tube 64 and seal cover 62, the front end of end cap 63 is provided with recess, seal cover 62 is located at the front end of end cap 63, and and be provided with between the recess of end cap 63 between the rear end face of packing ring 69 described rear end caps 12 and bearing 7 and be provided with a waveform packing ring 8, increase seal washer, improve sealing.The front end of described bearing 7 is provided with a sealing ring 71, and described front end housing 11 is provided with sealing gasket 9 with rotating shaft 3 contact positions.Described front end housing 11, rear end cap 12 are coated with sealant layer with the junction of shell 1, and shell 1 whole surface all is coated with anticorrosive coat, can increase the service life.
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.
