Abstract
The utility model discloses a kind of extension shaft electric machine structure, motor sets extension shaft, bearing is arranged on extension shaft, connected between bearing and motor by electric motor end cap, electric motor end cap both sides band is fluted, bearing, electric motor end cap opposite side groove and motor connection are installed, the bearing sets bearing (ball) cover close to the side of torque output in the groove of electric motor end cap side.The beneficial effects of the utility model are to ensure that the sealing of motor, and the injury to motor shaft is reduced again, maintenance rate is substantially reduced.Avoid increase bearing to use supported at three point simultaneously, reduce difficulty of processing, reduce abrasion.
Description
Technical field
The utility model is related to technical field of motors, a kind of extension shaft electric machine structure of specific design.
Background technology
With the continuous renewal of blower fan, pump class formation, motor crankshaft, which needs to be lengthened to certain length, could meet installation
The requirement of structure, the lengthening simply of motor shaft causes the amount of deflection and rigidity of projecting shaft not to reach actual requirement, causes off-axis to show
The generation repeatedly of elephant.Some producers constitute supported at three point, the machining accuracy of supported at three point in the additional a set of bearing of motor body
It is required that it is high, and also be difficult to reach requirement, bearing wear is fragile greatly, and concentricity is bad, off-axis phenomenon also occurs.
The content of the invention
The defect existed based on prior art, the utility model will be moved outside motor bearings, and bone is installed in motor original position of bearings
Frame sealing ring sealed electric-motor, the position from nearly torque output is arranged on by the bearing of outer shifting, and its specific technical scheme is, a kind of
Extension shaft electric machine structure, motor sets extension shaft, and bearing is arranged on extension shaft, connected between bearing and motor by electric motor end cap
Connect, electric motor end cap both sides band is fluted, bearing, electric motor end cap opposite side groove and electricity are installed in the groove of electric motor end cap side
Machine is connected, and the bearing sets bearing (ball) cover close to the side of torque output.
Further, the bearing is arranged close to one end of torque output.
Further, the electric motor end cap sets outside framework oil seal with motor shaft contact position.
Further, the bearing (ball) cover sets outside framework oil seal with motor shaft contact position.
Further, the bearing, electric motor end cap and motor are the integrated design.
Further, the electric machine structure is applied in blower fan, pump class.
The beneficial effects of the utility model are to ensure that the sealing of motor, and the injury to motor shaft is reduced again, is substantially reduced
Maintenance rate.Avoid increase bearing to use supported at three point simultaneously, reduce difficulty of processing, reduce abrasion.
Brief description of the drawings
Fig. 1 is extension shaft electric machine structure schematic diagram,
Fig. 2 is electric motor end cap side view,
Fig. 3 is electric motor end cap front view,
In figure：1st, motor, 2, motor shaft, 3, electric motor end cap, 4, bearing, 5, bearing (ball) cover, 6, outside framework oil seal, 7,
Electric motor end cap installs position of bearings, and 8, electric motor end cap connection motor position, 9, engaging lug, 10, bolt connecting hole.
Embodiment
In order to further illustrate the technical solution of the utility model, it is described with reference to the drawings as follows：One kind is used for blower fan or pump
The extension shaft electric machine structure of class, motor 1 sets extension shaft, and motor bearings 4 is outer to be moved, and bearing 4 is arranged on extension shaft, motor primitive axis
Position mounting framework oil sealing sealing motor is held, is connected between bearing 4 and motor 1 by electric motor end cap 3, bearing 4, electric motor end cap 3
It is the integrated design with motor 1.Electric motor end cap 3 is truncated cone-shaped, and the upper and lower surface of electric motor end cap 3 sets circular groove,
Bearing 4 is installed, the lower surface circular groove of electric motor end cap 3 is connected with motor 1, motor side in the upper surface circular groove of electric motor end cap 3
The lower surface surrounding of lid 3 is uniformly arranged in the middle of multiple engaging lugs 9, engaging lug 9 and sets bolt connecting hole 10, and electric motor end cap 3 passes through spiral shell
Bolt is connected with motor 1.The bearing 4 sets bearing (ball) cover 5 close to the side of torque output.Electric motor end cap 3 is contacted with motor shaft 2
Place sets outside framework oil seal 6, and bearing (ball) cover 5 sets outside framework oil seal 6 with the contact position of motor shaft 2.Bearing 5 is arranged close to torque output
One end, reduce injury to motor shaft 2, motor shaft is longer, bearing outset is from more remote, the motor of connection bearing 4 and motor 1
End cap 3 is longer.
