Description
Technical field
The utility model relates to the asynchronous motor field, especially a kind of asynchronous motor of high-efficiency bearing heat radiation.
Background technology
Threephase asynchronous.It mainly is comprised of stator and rotor two parts, is air gap between the stator and rotor.The rotor winding is as producing induced potential and produce electromagnetic torque, two kinds of its minute squirrel-cage and Wound-rotor types.The cage rotor winding is the winding of own short circuit, is placed with a conductor (material is copper or aluminium) at rotor in each groove, and conductor is longer than iron core, at the iron core two ends with two end ring with the conductor short circuit, form short-circuited winding.If iron core is removed, remaining winding shape is like squirrel, so claim the squirrel-cage winding.Squirrel-cage asynchronous motor is simple in structure, easy to manufacture, cost is low, operation maintenance is convenient, and it is widely used in the industrial and agricultural production, as prime mover of Electric Traction.But standard flange is installed closed asynchronous squirrel-cage motor, and temperature is higher in the cavity of flange installation end sealing, even reaches 80 ℃ of bearing temperatures above limit value, and bearing life is very short.
The utility model content
The applicant provides a kind of high efficiency and heat radiation motor for above-mentioned shortcoming of the prior art
, simple in structure, radiating efficiency is high.
The technical scheme that the utility model adopts is as follows:
The high efficiency and heat radiation motor comprises shell, is connected to the flange end cap of shell front end, the bearing of enclosure and rotating shaft; Described flange end cap comprises intermediate disc, and described intermediate disc connects outer disc by reinforcement; Form ventilation hole between the reinforcement; Have groove in the rotating shaft, be provided with circlip in the described groove; Near circlip place cover fin is arranged in the rotating shaft;
Further technical scheme is as follows:
4 to 8 of the quantity of described reinforcement and evenly distribution;
One annular groove is arranged on the described intermediate disc, evenly be provided with the thin ribs of disk and thick ribs in the annular groove;
Be annular boss between described reinforcement and the annular groove, uniform several installing holes on the annular boss;
The position of described installing hole and quantity are decided by the structure of shell;
Described fin and rotating shaft are that interference fit and several are arranged as one group.
The beneficial effects of the utility model are: the flange end cap is designed to the structure that communicates with the external world and increases fin in rotating shaft, increase area of dissipation, improved the radiating efficiency of motor internal, particularly the temperature at motor bearings place obviously reduces, simple in structure, effective.

Installation process of the present utility model is as follows:
The first step is installed in bearing 3 in the bearing mounting groove of flange end cap 18 first, by bolt 6 bearing (ball) cover 4 is connected and fixed;
Second step puts rotating shaft 2 to the flange end cap 18 that bearing 3 is housed, and by bolt 7 flange end cap 18 is connected on the motor housing 1;
The 3rd step sticked into circlip 19 in the above the groove of rotating shaft 2, several heat radiations 5 was respectively installed in the rotating shaft 2 again.
More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range within protection range of the present utility model, can be done any type of modification referring to claim.
