Abstract
The utility model discloses a better motor shaft of equilibrium, including the head rod that connects gradually, the annular knurl pole, first polished rod, second polished rod and second connecting rod, all be equipped with the spline on the outer disc of head rod and second connecting rod, rolling on the outer disc of annular knurl pole have a straight knurling, be equipped with the keyway of slope on the outer disc of first polished rod along the axial, be equipped with annular (holding) chuck between first polished rod and the second polished rod, be equipped with the buffering packing ring between first polished rod terminal surface and the annular (holding) chuck, evenly distributed has a plurality of balancing holes on the annular (holding) chuck, it has a plurality of location shallow slot to distribute on the second polished rod. The utility model discloses the operation in -process is difficult for that the appearance is radially skidded and the axial cluster moves the phenomenon, has better antitorque ability, and adopts the design that sets up the balancing hole on annular (holding) chuck, has heightened the balance quality of motor shaft effectively, and stability is good, has guaranteed the precision of motor shaft effectively, has improved life, has guaranteed the normal operating of motor.
Description
Technical field
The utility model relates to technical field of motors, is specially the good motor shaft of a kind of balance.
Background technique
Motor refers to a kind of calutron realizing electric energy conversion according to the law of electromagnetic induction or transmit.Motor shaft is one of them vitals, and its performance directly affects the performance of whole motor.Traditional motor shaft structure is reasonable not, and it is convenient not to install and use, and anti-twisting property is poor, and easily cause members slip and axial motion phenomenon, mounting accuracy of component is not high, and balance quality is not good, and working life is lower.
Model utility content
The purpose of this utility model is to provide the good motor shaft of a kind of balance, reasonable not to solve motor shaft structure traditional in prior art, it is convenient not to install and use, anti-twisting property is poor, easily cause members slip and axial motion phenomenon, mounting accuracy of component is not high, and balance quality is not good, the problem that working life is lower.
For achieving the above object, the technical solution adopted in the utility model is:
The good motor shaft of a kind of balance, it is characterized in that: include the head rod connected successively, annular knurl bar, first polished rod, second polished rod and the second connecting rod, the periphery of described head rod and the second connecting rod is equipped with spline, on the periphery of described annular knurl bar, rolling has straight knurling, the periphery of described first polished rod is provided with vertically the keyway of inclination, annular chuck is provided with between described first polished rod and the second polished rod, buffer gasket is provided with between described first polished rod end face and annular chuck, described annular chuck is evenly distributed with some equalizing orifices, described second polished rod is distributed with multiple location shallow slot.
The described good motor shaft of a kind of balance, is characterized in that: described motor shaft adopts high strength alloy material to make.
The beneficial effects of the utility model are:
The utility model is simple and reasonable, easy to install, radial skidding and axial motion phenomenon is not easily there is in operation process, there is good anti-twisting property, and adopt the design that equalizing orifice is set in annular chuck, effectively heightened the balance quality of motor shaft, good stability, effectively ensure that the precision of motor shaft, improve working life, ensure that the normal operation of motor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
