Abstract
The utility model discloses a kind of power equipment rotor main shaft without moment of flexure drive mechanism.Comprise motor base and rotating shaft, rotating shaft is by Flange joint main shaft, main shaft is positioned at a rotor cap, motor base front end connects the extension set that a section is enclosed within main shaft periphery, front-end of spindle is fixedly connected with a wheel hub by tension mechanism, and the stage casing of wheel hub and back segment are arranged on extension set respectively by former and later two bearings.The utility model tool has the following advantages: eliminate the moment of flexure that in power equipment, connection rotating shaft and electric machine main shaft bear, disperse rotating shaft to the power stream of motor base, by extension set (but not passing through main shaft), motor base is allowed directly to bear moment of flexure from rotor, make weight from rotor completely by motor base load, main shaft only bears the moment of torsion that rotor turns brings, thus reduces the requirement of main axe intensity; To the loading demands of main shaft and bearing when reducing equipment de-sign, more reasonable structure, effectively reduces equipment cost, improves the fail safe of structure.
Description
Technical field
The utility model relates to a kind of special torque transmission structure being applicable to power equipment rotor and being connected with motor, and specifically a kind of power equipment rotor main shaft is without moment of flexure drive mechanism, belongs to electrical equipment technical field.
Background technology
Rotor in power equipment and the connected mode of motor, to be generally fixed in cabin on motor base by rotor by transmission main shaft and bearing; The rotor of main shaft connection device and motor (or motor speedup structure), transmit the moment of flexure from rotor and moment of torsion, and most of moment of flexure is passed to motor base and supporting construction by bearing, this structure is very high to the requirement of strength of main shaft; There is no a kind of reduction at present or remove the structure of base bearing by moment of flexure, to reduce main shaft load, and then reducing hidden danger and saving complete machine cost.
Summary of the invention
The technical problems to be solved in the utility model is to provide one can reduce main shaft load, and then reduces hidden danger, saves the power equipment rotor main shaft of complete machine cost without moment of flexure drive mechanism.
In order to solve the problems of the technologies described above, power equipment rotor main shaft of the present utility model is without moment of flexure drive mechanism, comprise motor base and rotating shaft, rotating shaft is by Flange joint main shaft, main shaft is positioned at a rotor cap, motor base front end connects the extension set that a section is enclosed within main shaft periphery, and front-end of spindle is fixedly connected with a wheel hub by tension mechanism, and the stage casing of wheel hub and back segment are arranged on extension set respectively by former and later two bearings.
Described rotating shaft is the associated gear case input of motor transmission shaft or motor.
The rear end of described extension set is provided with the rear end cap that is positioned at the rear end face place of rearward-facing end bearing.
The front end of described extension set is provided with the front end housing that is positioned at the front end face place of bearing above.
Described tension mechanism is expansion sleeve.
The utility model tool has the following advantages:
By connecting extension set at motor base leading portion, thus extend the standing part of motor base; Rotor hub is directly connected with standing part by bearing, makes the rotor weight from wheel hub be directly delivered to motor base; Main shaft is through extension set, front end and wheel hub are fixed by forms such as expansion sleeves, rear end connection rotating shaft, thereby eliminate the moment of flexure that in power equipment, connection rotating shaft and electric machine main shaft bear, disperse rotating shaft to the power stream of motor base, by extension set (but not passing through main shaft), motor base is allowed directly to bear moment of flexure from rotor, make weight from rotor completely by motor base load, main shaft only bears the moment of torsion that rotor turns brings, thus reduces the requirement of main axe intensity; To the loading demands of main shaft and bearing when reducing equipment de-sign, more reasonable structure, effectively reduces equipment cost, improves the fail safe of structure.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model power equipment rotor main shaft without moment of flexure drive mechanism.
Embodiment
Below in conjunction with the drawings and specific embodiments, power equipment rotor main shaft of the present utility model is described in further detail without moment of flexure drive mechanism.
As shown in the figure, power equipment rotor main shaft of the present utility model is without moment of flexure drive mechanism, comprise motor base 1 and rotating shaft 2, rotating shaft 2 is by Flange joint main shaft 3, main shaft 3 is positioned at a rotor cap 4, motor base 1 front end connects the extension set 5 that a section is enclosed within main shaft periphery, main shaft 3 front end is fixedly connected with a wheel hub 7 by tension mechanism 6 (tension mechanism is expansion sleeve or other locking mechanism), and the stage casing of wheel hub 7 and back segment are arranged on extension set 5 respectively by former and later two bearings; Said rotating shaft both can be motor transmission shaft also can be the associated gear case input of motor, the rear end of extension set 5 is provided with the rear end cap 8 that is positioned at the rear end face place of rearward-facing end bearing, the front end of extension set 5 is provided with the front end housing 9 that is positioned at the front end face place of bearing above, and former and later two bearings can be made thus to be sealed by front end housing 9 and rear end cap 8;
Utility model works process is as follows:
In power equipment course of normal operation, for generating equipment, provide twisting resistance by external force to impeller of rotor, drive wheel hub 7 to rotate, because wheel hub 7 and main shaft 3 are fixed, so by moment of torsion by main shaft to generator transmission; Secondly, because rotor turns plane is subject to the impact of uneven load and rotor deadweight, above-below direction pitching moment of flexure can be subject to, rotor is connected with main shaft by expansion sleeve in addition, simple transmitting torque, reduces the load of main shaft, and eliminates major part to the hurtful mechanical stress of driving-chain, due to the structure of the utility model design, this moment of flexure directly will be delivered to motor base by bearing.
