Description
Technical field
The utility model is related to a kind of hollow shaft motors, belong to motor renovation technique field.
Background technology
Conventional motors hollow axis structure requires extremely strictly in terms of machining accuracy and concentricity, and the motor casing of motor passes through
Electric machine flange end cap is connected with apparatus casing, electric machine flange end cap and rear end cap by two sets of rotor bearings and hollow axis connection,
Equipment bearing, two sets of included bearings of motor itself, in addition the bearing of its driving equipment, three sets of bearings are provided in apparatus casing
It carries simultaneously, if machining accuracy does not reach requirement, tree-pointb earing will will appear the state having a contest, to keep bearing friction impaired
Seriously, bearing life is reduced, load is aggravated, current of electric increases, and increases loss, or even influence the normal use of equipment.
Invention content
According to defect of the existing technology, the purpose of this utility model is to provide a kind of hollow shaft motor, cancels motor
Motor casing is directly fixed on device housings by flange end cap, removes the spring bearing of rotor, by rotor directly quilt
Support is installed on the main shaft of equipment, when the rotor is turning, is directly driven machine spindle operating, is reduced friction, reduce loss.
To achieve the above object, technical solution used by the utility model is：A kind of hollow shaft motor, including motor casing
Body, hollow shaft, rotor and end cover；Hollow shaft is set inside the electric machine casing, rotor, electric machine casing are arranged on hollow shaft
End cover is arranged in rear end, and the electric machine casing connects apparatus casing to be driven, machine spindle is arranged in apparatus casing to be driven,
Machine spindle extends in motor hollow shaft, and equipment bearing is arranged in the machine spindle.
Further, the electric machine casing is directly connected to apparatus casing to be driven by bolt.
Further, one end of the hollow shaft extends in end cover, end cover and is set on hollow shaft
Outside framework oil seal is arranged in rotor contact position.
The beneficial effects of the utility model are：The utility model is simple in structure, reduces electric machine structure component, easy for installation,
Reduce main shaft friction, reduces loss.
