Operation principle of the present utility model is:
This utility model, by independently driving primary rotor 3 and working shaft 6, can break through one-level bearing 2 and two
Level bearing A5, the arbitrary bearing of secondary bearing B13 be used alone in the case of limit speed.Particularly as follows:
Power is passed to one-level driven pulley 10 by primary motor, because one-level driven pulley 10 and secondary bearing seat B11 are integrated knot
Structure, and then drive primary rotor 3 and the outer ring rotating of secondary bearing B13, primary rotor 3 drives again the inner ring of one-level bearing 2 to turn
Dynamic；Further, because primary rotor 3 is structure as a whole with secondary bearing seat A4, drive secondary bearing A5's by secondary bearing seat A4
Outer ring rotating.Meanwhile, power is passed to two grades of driven pulleys 15 by mair motor, and these two grades of driven pulleys 15 drive working shaft 6 with design
Actual speed rotates；Working shaft 6 drives again the inner ring of secondary bearing A5 and the inner ring of secondary bearing B13 to rotate.
Such as, the limit speed of one-level bearing 2 is that 3500r/min is (i.e. maximum relative between the inside and outside circle of one-level bearing 2
Rotating speed is 3500r/min), the limit speed of secondary bearing A5 and secondary bearing B13 is 5500r/min (i.e. secondary bearing A5
And maximum relative rotation speed is 5500r/min between the inside and outside circle of secondary bearing B13).One-level driven pulley 10 is by primary rotor 3
The working speed making one-level bearing 2 is that (because the outer ring of one-level bearing 2 does not rotates, therefore inner ring revolves 2300r/min with primary rotor 3
Turn, be 2300r/min relative to the rotating speed of outer ring)；Meanwhile, one-level driven pulley 10 drives two grades of axles by secondary bearing seat B11
Hold the outer ring rotating speed of B13 and drive the outer ring rotating speed of secondary bearing A5 to be 2300r/min by secondary bearing seat A4.By main electricity
Machine drives two grades of driven pulleys 15 to rotate, and makes the rotating speed of two grades of driven pulleys 15 reach 6500r/min relative to support stand；Working shaft
6 rotate with two grades of driven pulleys 15, and rotating speed reaches 6500r/min, and drives the inner ring of secondary bearing A5 and the interior of secondary bearing B13
Circle rotating speed all reaches 6500r/min；And at this moment secondary bearing A5 and secondary bearing B13 is relative to the working speed of one-level bearing 2
Only 4200r/min (the namely inner ring rotating speed 6500r/min of secondary bearing A5 and secondary bearing B13 and outer ring rotating speed
The difference of 2300r/min), final two grades of driven pulleys 15 can reach 6500r/min, i.e. work relative to the working speed of support stand
The rotating speed making axle 6 can reach 6500r/min.And be used alone one-level bearing 2 and primary rotor 3 can only be made to reach capacity rotating speed
3500r/min, is used alone secondary bearing A5 or secondary bearing B13 and working shaft 6 can only be made to reach capacity 5500 revs/min of rotating speed
Clock.Secondary bearing A5 working speed in secondary bearing seat A4 and secondary bearing B13 work in secondary bearing seat B11
Rotating speed all only has 4200r/min (speed discrepancy of inside and outside circle), well below the limit speed 5500r/min of each secondary bearing,
Achieve secondary bearing on the premise of not reaching self limit speed, make the purpose that the rotating speed of working shaft 6 is greatly improved.
