Description
Technical field
The utility model relates to a kind of asynchronous motor, especially relates to a kind of threephase asynchronous.
Background technology
By inquiry after the actual conditions of present processed glass industry, there are following shortcomings in grinding head motor in the domestic electric machine industry: be configured to conventional former and later two bearings, find that operating mode is more abominable, intensity of load is bigger, long-time high strength continuous operation makes bearing life shorten significantly, brings unnecessary loss to the user.The axial endplay control of motor is tight inadequately, can't satisfy the demand and carry out the customer requirements of high accuracy ground glass.Motor dust cover design is tight inadequately, can't prevent effectively that sealing spatters the erosion with dust.
Summary of the invention
The purpose of this utility model is exactly that a kind of reliable, noise is low, flexibility is high, performance is high, the life-span is long threephase asynchronous is provided in order to overcome the defective that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of threephase asynchronous; comprise support; be positioned at the band winding stator core of support; be positioned at band winding stator core and with its cage rotor in relative rotation; be positioned at the rotating shaft of cage rotor inside; be installed in the front end housing and the rear end cap of support front and back; it is characterized in that; also comprise fore bearing; rear bearing; back-up ring; reinforced seal; the fore bearing inner cap; the fore bearing enclosing cover; protective cap; described fore bearing front end is provided with packing ring successively; stop washer; axle sleeve; be provided with the O RunddichtringO between described front end housing and the fore bearing enclosing cover; described fore bearing front end and back-up ring; reinforced seal connects; described fore bearing; back-up ring; reinforced seal is positioned within the fore bearing enclosing cover, and described fore bearing enclosing cover is positioned within the protective cap.
Described fore bearing is made up of 2 paired duplex angular contact ball bearings, is installed in the front end of rotating shaft.
Described rear bearing is common deep groove ball bearing, is installed in the rear end of rotating shaft.
Compared with prior art, the utlity model has following advantage:
Front end adopts paired angular contact ball bearing, improve bearing capacity greatly, exclusive locking mechanism has effectively been controlled axial endplay, and is reliable, noise is low, the flexibility height, performance is efficient, can directly connect the high-precision grinding processing that the emery wheel seat is used for grinding machine at the shaft extension end, simultaneously, unique head protector design makes motor plant and can directly be connected with client's emery wheel seat in use, makes the fail safe reliability also have the life-span to increase greatly.
