Abstract
The utility model discloses a waterproof motor. The waterproof motor comprises a rotor, a rotation shaft and a casing, wherein two ends of the casing are respectively provided with a front end cover and a back end cover, the back end cover is provided with a shaft hole for penetration of the rotation shaft, periphery of the back end cover is covered by an air cover, an inner side of the back end cover is provided with a bearing chamber used for mounting a bearing, a waterproof cover is arranged between the back end cover and the air cover, the waterproof cover is provided with a conical extension hole for penetration of the rotation shaft, the conical extension hole penetrates through the shaft hole of the back end cover, and an end portion of the conical extension hole contacts with a back end face of the bearing. Tight cooperation between the rotation shaft of the waterproof motor and the conical extension hole of the back end cover is realized, and the waterproof motor further has properties of good sealing performance, simple structure, convenient manufacturing and greatly reduced cost.
Description
Technical field
The utility model relates to a kind of waterproof machine.
Background technology
General motor water resistance is imperfection all, even the sealing motor, because seal approach imperfection, trickle for a long time.At the motor of trickle environment or outwork, as the motor on the cooling tower, not only to be exposed to the sun, also will often be drenched with rain, moreover its operational environment is also relatively moister, because long-time trickle, common motor is easy to watered and wetting, cause short circuit easily, especially have the slit between back end cover for motor and the rotating shaft, be very easy to cause the motor water inlet, some waterproof machines also appear in the market, but complex structures all, the manufacturing cost height is not suitable for large-scale popularization.
The utility model content
The utility model provides a kind of simple in structure, with low cost, the waterproof machine of good water-proof effect in order to overcome the deficiencies in the prior art.
To achieve these goals, the utility model is by the following technical solutions: a kind of waterproof machine, 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.
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 calmly.
In sum, the utility model has following advantage: cooperate between the taper elongated hole of the rotating shaft of this waterproof machine and rear end cap closely, and good seal performance, simple in structure, easily manufactured, greatly reduce cost.
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 waterproof machine, 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; Be provided with a waveform packing ring 8 between the rear end face of described rear end cap 12 and bearing 7, 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.
