Description

TECHNICAL FIELD

[0001] The present application relates to the field of transmission technology, in particular to a flange shaft. BACKGROUND

[0002] In the existing industrial energy-saving speed regulation scheme, there is a winding type speed regulator, which includes two rotors, and the winding of the winding rotor needs to recover slip energy through a carbon brush slip ring. The bearing support and electrical connection of the winding rotor need to be considered simultaneously in the mechanical aspect.

[0003] The existing scheme 1 is to arrange the support bearing of the winding rotor outside the slip ring, so that the slip ring and the bearing do not cross in position. The disadvantage of this scheme is that when the rotor and the slip ring are long, the bearing outside the position will cause the span between the support bearings to be too long, affecting the dynamic characteristics of the rotor, and the carbon brush slip ring assembly is a heat source. By wrapping the slip ring inside, the heat dissipation of the slip ring needs to be considered again, and too much heat of the slip ring cannot be transferred to the bearing.

[0004] The existing scheme 2 is to additionally arrange an interference fit threading shaft sleeve on the rotating shaft, process a plurality of threading grooves on the rotating shaft, pass the winding lead from the groove, then install the threading shaft sleeve, and then install the support bearing on the threading shaft sleeve. The disadvantage of this scheme is that the assembled threading shaft sleeve needs to be separately processed, then hot-mounted, and then re-processed after installation to ensure the accuracy of the entire assembly. The heat treatment process of the threading shaft sleeve also needs to be considered additionally, which is slightly cumbersome. SUMMARY

[0005] The technical problem to be solved by the present application is the conflict between the electrical wiring and the mechanical bearing support of the winding rotor of the existing double-rotor speed regulator.

[0006] The technical scheme adopted by the present application to solve the technical problem is a flange shaft, which comprises a flange plate and a rotating shaft body. An inner bearing chamber is formed in the middle of the left side of the flange plate. An outer bearing position is arranged on the outer arc surface of the rotating shaft body. An internal shaft hole is formed in the rotating shaft body and is in communication with the inner bearing chamber. A stepped hole is formed in the internal shaft hole. An assembled lubricating oil pipe is inserted into the stepped hole. An internal threading hole outlet and an internal threading hole inlet are formed in the outer arc surface of the rotating shaft body.

[0007] An oil injection nozzle is formed in the outer surface of the rotating shaft body and is in communication with the inner stepped hole.

[0008] A sealing ring is arranged on the inner surface of the stepped hole and the outer assembly surface of the assembled lubricating oil pipe.

[0009] A winding threading hole is formed in the inner part of the flange plate.

[0010] A bolt assembly hole for connecting the winding rotor is formed in the inner part of the flange plate.

[0011] The internal threading hole outlet and the internal threading hole inlet are obliquely arranged in the inside of the rotating shaft body.

[0012] The beneficial effects of the present application are:

[0013] (1) The flange shaft has two bearing positions, which makes it more versatile;

[0014] (2) The rotating shaft body has a plurality of threading holes for leading out the winding wire of the outer winding rotor winding, which facilitates layout and installation, and the threading holes and the outer bearing position do not interfere with each other;

[0015] (3) A stepped hole is processed at the shaft core position, and the internal assembly lubricating oil pipe can separate the internal oil circuit and the ring channel, and the internal space utilization is higher. BRIEF DESCRIPTION OF DRAWINGS
