Abstract
The utility model relates to a directly-connected-type roller way motor with a square flange and a taper hole shaft, which comprises a motor base, a flange end cap, a motor shaft, a bearing, a bearing retaining ring, a stator, a rotor and a rear end cap. The directly-connected-type roller way motor with a square flange and a taper hole shaft is characterized in that the motor flange end cap is in a square structure which can be fittingly connected with a square reduction box body integrally, an O-shaped sealing ring is mounted outside a bearing chamber of the flange end cap, a portion of the bearing is embedded on the square flange end cap while the other portion of the bearing is embedded on a reduction box, an oil seal is disposed at a position at which the rear end of the bearing runs through the motor shaft, and the motor shaft is in a taper hole shaft structure. The directly-connected-type roller way motor has the advantages that the motor is novel in structure, convenient in installation, accurate in positioning, stable in running and low in noise, the diameter of a gear of the reduction box is smaller under the condition that the gear has higher deceleration, so that the strength of the gear can be increased conveniently, sealing and lubricating effect is better, and service life of the motor is long.
Description
Technical field
The utility model belongs to the motor manufacturing technology field, particularly relates to a kind of associated mode square flange dish taper-bored spindle electric machines for roller.
Background technology
The electric machines for roller of metallurgy industry use at present all connect with reduction box, reach the purpose of reduction of speed by the speed reducing ratio of gear.Existing electric machines for roller are because its structural limitations, have following deficiency: 1, the bearing of motor adopts solid lubrication fat to be lubricated, the oil sealing of motor is installed on the front end of motor bearings, in actual the use, because roller bed is carried a large amount of high temperature billet steels, make the bearing of motor understand the dry damage of oil starvation, make motor stuck, and then cause motor to burn out, shortened the useful life of motor because of stall because of long term high temperature.When 2, motor was installed, flange end cap and reduction box junction did not have sealing ring, and its sealing effectiveness is relatively poor.3, the shaft extension of motor is cylindrical d-axis, reduction gearing is enclosed within d-axis and stretches and utilize shaft block ring to block, because steel billet can produce fierce bump to the roller bed roller, the intensity of shaft block ring is lower, make the gear of motor easily come off from motor shaft, damage the deceleration system in the reduction box, reliability is lower.
Summary of the invention
The utility model provides a kind of simple in structure, easy for installation and associated mode square flange dish taper-bored spindle electric machines for roller that seal lubrication is good for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: associated mode square flange dish taper-bored spindle electric machines for roller, comprise electric machine stand, flange end cap, motor shaft, bearing, end ring, stator, rotor and rear end cap, it is characterized in that: described motor flange end cap is equipped with the O RunddichtringO for mating the square structure that fuses with square reductor casing outside flange end cap bearing chamber; A described bearing part is inlaid on the square square flange end cap, and another part is inlaid on the reductor, and described bearing rear end and motor shaft perforation place are provided with and prevent that the reduction box thin oil from entering the oil sealing of motor internal, and described motor shaft is the taper-bored spindle structure.
The utility model can also adopt following technical scheme:
The tapering of described motor taper-bored spindle is a Morse's taper.
Described square flange end cap and taper-bored spindle perforation place are provided with rubber oil seal with reinforce.
Advantage and the good effect that the utlity model has are: because the utility model adopts technique scheme, and the novel structure of motor, easy for installation, accurate positioning; The bearing part of motor is inlaid on the square square flange end cap, and another part is inlaid on the reductor, both can play the effect of support motor, also can support reducer gear simultaneously, guarantees that motor rotation is steady, and noise is low; The gear of reductor is under the bigger situation of speed reducing ratio, and gear diameter is less, is convenient to improve the intensity of gear, and sealing and lubricant effect are better, long service life.In addition, the lubricated of motor bearings is the thin oil lubricant that adopts in the reduction box, and the oil sealing of motor is positioned over the back of bearing, can prevent that like this thin oil of reduction box from entering motor internal, and sealingly secure is reliable.
