Abstract
The invention discloses a high-strength motor shaft. The high-strength motor shaft comprises a front connection rod and a rear connection rod, wherein a knurled rod, a first polished rod and a second polished rod are sequentially connected between the front connection rod and the rear connection rod; splines are arranged on the outer circle surfaces of the front connection rod and the rear connection rod; the splines on the front connection rod extend to the end side of the front connection rod; straight-line knurls are rolled on the outer circle surface of the knurled rod; a plurality of axial bar grooves are distributed at equal intervals in the outer circle surface of the first polished rod; a plurality of cross-shaped reinforcing groove nodes are distributed on the bar grooves. The high-strength motor shaft is simple and reasonable in structure, convenient to mount and use, small in possibility of skidding in the radial direction in the operation process, relatively good in torsion resistance, capable of conveniently locating and welding rib plates, good in stability and not easy for stress concentration and deformation; the precision of the motor shaft is effectively guaranteed; the service life of the motor shaft is prolonged; the normal operation of the motor is guaranteed.
Description
Technical field
The present invention relates to technical field of motors, be specially a kind of high strength motor shaft.
Background technique
Motor refers to a kind of calutron of realizing electric energy conversion or transmit according to the law of electromagnetic induction.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, easily causes parts to skid, and floor positioning welding is inconvenient, and weld easily produces stress and concentrates and be out of shape, and installation precision is not high, and working life is lower.
Summary of the invention
The object of this invention is to provide a kind of high strength motor shaft, 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 parts to skid, floor positioning welding is inconvenient, and weld easily produces stress and concentrates and be out of shape, installation precision is not high, the problem that working life is lower.
For achieving the above object, the technical solution used in the present invention is:
A kind of high strength motor shaft, it is characterized in that: include front connecting rod and rear connecting rod, between described front connecting rod and rear connecting rod, be connected with annular knurl bar, the first polished rod and the second polished rod in turn, on the periphery of described front connecting rod and rear connecting rod, be equipped with spline, spline on described front connecting rod extends to front connecting rod end face, on the periphery of described annular knurl bar, rolling has straight knurling, the periphery equal intervals of described the first polished rod is distributed with a plurality of axial arranged bar-shaped troughs, is distributed with a plurality of crosss and reinforces groove node on described bar-shaped trough.
Described a kind of high strength motor shaft, is characterized in that: between described the first polished rod and the second polished rod, be provided with annular slot.
Described a kind of high strength motor shaft, is characterized in that: described motor shaft adopts high strength alloy material to make.
Beneficial effect of the present invention is:
The present invention is simple and reasonable, easy to install, in operation process, be not prone to radially skidding, have good anti-twisting property, floor positioning welding is convenient, good stability, being difficult for producing stress concentrates and is out of shape, the precision that has effectively guaranteed motor shaft, has improved working life, has guaranteed the normal operation of motor.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
