Accompanying drawing explanation
The accompanying drawing forming a application's part is used to provide a further understanding of the present invention, and schematic description and description of the present invention, for explaining the present invention, does not form inappropriate limitation of the present invention.In the accompanying drawings:
Fig. 1 is the detonation configuration schematic diagram of embodiment of the present invention shaft.
Wherein, being labeled as in above-mentioned accompanying drawing:
1, standard shaft; 11, assembly department; 3, auxiliary shaft part.
Embodiment
Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
As shown in Figure 1, comprise standard shaft 1 and auxiliary shaft part 3 according to the rotating shaft in the embodiment of the present invention, standard shaft 1 comprises assembly department 11, and auxiliary shaft part 3 is arranged on assembly department 11 removably.The present invention, by rotating shaft being set to standard shaft 1 and auxiliary shaft part 3, being about to the auxiliary shaft part 3 that more complicated rotating shaft is divided into the relatively simple standard shaft 1 of structure and is arranged on standard shaft 1, thus reducing difficulty of processing.Add man-hour, the relatively existing turning shaft structure of standard shaft 1 reduces, and processes and locates all more convenient, can effectively improve or ensure the machining accuracy of significant points, improving reliability.In addition, auxiliary shaft part 3 is detachable, and when wearing and tearing or fault, only need change corresponding auxiliary shaft part, the replaceability of rotating shaft is good.
Particularly, the standard shaft 1 in Fig. 1 is the less multidiameter shaft of step number, and manufacturing is got up comparatively easy, and by installing auxiliary shaft part 3 on standard shaft 1, can obtain the rotating shaft that structure is comparatively complicated.Standard shaft 1 also can be the simple cylinder axis of manufacturing (not shown), and by installing auxiliary shaft part on cylinder axis, can obtain baroque rotating shaft equally, whole rotating shaft manufacturing is got up relatively easily.More specifically, take rotating shaft as motor shaft be example, the topmost position of motor shaft be all arranged on standard shaft 1 as bearing position, encoder position, rotor core position etc., preferentially can process according to technological level in course of working.Due to standard shaft 1 designs simplification after disassembling, the processing at more difficult position can be completed under clamped one time, so all have higher coaxality between each main portions of standard shaft 1.
Relatively, position relatively low to required precision in rotating shaft, the changeover portion as bearing shoulder block, brake shoulder block and each ladder position then can be designed as auxiliary shaft part, then assembles on standard shaft 1, thus is assembled into complex structure, the rotating shaft that precision is high.
Usually, for realizing dismountable installation between auxiliary shaft part 3 and standard shaft 1, auxiliary shaft part 3 has the mounting hole suitable with the shape of cross section of assembly department 11, auxiliary shaft part 3 is set on the assembly department 11 of standard shaft 1 by mounting hole.Preferably, the mounting hole on auxiliary shaft part 3, auxiliary shaft part 3 and standard shaft 1 have identical central axis, thus can ensure to keep good coaxality between each position of mounted rotating shaft.Reliable fixing in order to ensure, the mounting hole on auxiliary shaft part 3 and assembly department 11 interference fit on standard shaft 1.Be understandable that, mounting hole and assembly department 11 offer screw thread, and the mode that mounting hole and assembly department 11 are threaded connection can realize object of the present invention equally, can realize reliable fixing simultaneously.As required, when the mounting hole on auxiliary shaft part 3 and assembly department 11 elastic conjunction on standard shaft 1, auxiliary shaft part 3 can adopt hot jacket mode to be assemblied in assembly department 11 on standard shaft 1, and the technique of colding pressing also can be adopted to realize elastic conjunction.
See Fig. 1, the quantity of auxiliary shaft part 3 is multiple, and specifically determine according to the complexity of rotating shaft and the situation of standard shaft 1, such as rotating shaft is more complicated, and the ladder namely in corresponding rotating shaft is more, and the quantity of auxiliary shaft part 3 is more.Wherein, the quantity of auxiliary shaft part 3 can be more than assembly department 11 quantity, thus the assembly department 11 on standard shaft 1 can install different auxiliary shaft parts 3 to adapt to different demands.
Preferably, the standard shaft 1 in the embodiment of the present invention is also provided with limit structure (not shown), limit structure is used for carrying out axially locating to auxiliary shaft part 3, the structure of whole rotating shaft thus more reliable and more stable.Particularly, such as, process annular stepped in the side of standard shaft assembly department, auxiliary shaft part when mounted side, against this ladder, thus realizes restriction to axial position.
Preferably, standard shaft 1 and auxiliary shaft part 3 adopt different materials, and such as: standard shaft 1 is common carbon steel, the material of auxiliary shaft part 3 is the alloyed steel of more high strength; Standard shaft 1 is common carbon steel, and the material of auxiliary shaft part 3 is spheroidal graphite cast iron; Standard shaft 1 is common carbon steel, and the material of auxiliary shaft part 3 adopts alloy.Further, in processing technology, to auxiliary shaft part 3 through Quenching Treatment to improve hardness.Standard shaft 1 and auxiliary shaft part 3 adopt different materials, thus can reduce cost of material under the prerequisite meeting production requirement.
Particularly, shown in composition graphs 1, in rotating shaft of the present invention, when ensureing that rotating shaft main body is constant, length and the tolerance of size of each shaft part can be adjusted arbitrarily according to the demand of practical structures, to meet supporting the use of different size chain and part; In addition, as the position that the needs such as bearing shoulder block, brake position shoulder block have compared with high verticality and structural strength, the material at auxiliary shaft part position can replace with the alloyed steel of more high strength or carry out Quenching Treatment to improve hardness to corresponding construction before assembly, solves the problem that part shaft part can not get both to the tolerance of size precision of aft-loaded airfoil and high hardness simultaneously.
The present invention also provides a kind of motor, comprises aforesaid rotating shaft, thus ensures rotating shaft precision, reduces difficulty of processing, improves reliability.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
