Abstract
The utility model discloses a seal motor, which comprises a motor, a magnetic driving part is positioned behind the motor, and the output shaft of the magnetic driving part is arranged on the bearing seat that is arranged in the magnetic driving part. The motor, the magnetic driving part and the magnetic driving bearing seat are all arranged in an unsplit casing. As the bearing seat and the magnetic drive are in the same space, the utility model has the advantages of rational and compact structure, small volume, and convenient usage.
Description
Technical field:
The utility model relates to a kind of motor.
Background technology:
Now in sealing transmission design, always motor, magnetic transmission, bearing pedestal three parts are coupled together uses by flange with bolt, seem not compact, it is inconvenient to use.
Summary of the invention:
It is a kind of rational in infrastructure, compact that the purpose of this utility model is to provide, and volume is little, sealed electric-motor easy to use.
Technical solution of the present utility model is:
A kind of sealed electric-motor comprises the motor part, after the motor part magnetic running part is set, and the output shaft of magnetic running part is loaded on the bearing pedestal of magnetic transmission inside, it is characterized in that: motor part, magnetic running part, magnetic power transmission shaft bearing are loaded in the shell.
Magnetic power transmission shaft bearing is arranged in the magnetic transmission space; The magnetic running part comprises the active magnetic assembly that is connected with motor shaft, driven magnetic assembly and seal closure, and the seal closure inside top that is provided with between driven magnetic assembly and the active magnetic assembly is provided with a spindle socket, the fore bearing of dress output shaft in the spindle socket.
The rear bearing of output shaft is loaded on shell end cap position.The corresponding position of seal closure between adjacent active magnetic is provided with one or more horizontal reinforcement.
The utility model is rational in infrastructure, compact, volume is little, easy to use, be that magnetic drive technology and motor are combined, an integral body of formation, similar on the profile to common electric machine, a projecting shaft is arranged, a connecting flange is arranged, but it also has the zero leakage sealing function except the function that the moment of rotating is arranged.The utility model is for avoiding eddy-current heating, and the seal closure material can be selected nonmetallic materials for use, as Reinforced Nylon, strengthens poly-tetrafluoro etc.
Nonmetallic materials and steel comparisons such as plastics, intensity is not high, and under the uniform pressure situation, the seal closure wall thickness is wanted corresponding increase, thereby has also increased the distance of inside and outside magnetic, has reduced maximum magnetic flux moment.In magnetic transmission active length, require cone wall thickness thin as far as possible, but be unlikely to when pressurization, to cause the very big distortion that bloats.Especially plastic seal cover, its creep amount of bloating is very big.The principle big more according to active length, that the amount of bloating is big more, the utility model have increased by one or more horizontal ribs on seal closure, to reach the purpose of cutting apart the active length corresponding with magnetic length.
Output shaft is mainly exported torque, but also will bear certain moment of flexure.So two bearings are arranged, and will draw back distance between bearings.For when increasing this spacing, be unlikely to too much to increase the length of sealed electric-motor again, special at spindle socket of seal closure top design, place upper bearing (metal).Like this, bearings and magnetic transmission are placed the same space section, utilized the space to greatest extent, saved one section and be exclusively used in the bearing pedestal of placing pair of bearings.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the configuration diagram of an embodiment of the utility model.
Fig. 2 is the configuration diagram of seal closure.
Embodiment:
A kind of sealed electric-motor comprises motor part 1, and the magnetic running part is set after the motor part 1, and the output shaft 8 of magnetic running part is loaded on the bearing pedestal of magnetic transmission inside, and motor part 1, magnetic running part, magnetic power transmission shaft bearing are loaded in the shell 2.Magnetic power transmission shaft bearing is arranged in the magnetic transmission space; The magnetic running part comprises the active magnetic assembly 4 that is connected with motor shaft 3, driven magnetic assembly 5 and seal closure 6, and seal closure 6 inside top that are provided with between driven magnetic assembly 5 and the active magnetic assembly 4 are provided with a spindle socket, the fore bearing 7 of dress output shaft 8 in the spindle socket.The rear bearing 9 of output shaft 8 is loaded on shell 2 end cap positions.The corresponding position of seal closure 6 between adjacent active magnetic 11,12 is provided with one or more horizontal reinforcement 10.
