Abstract
The invention discloses a connection structure for segmented shaft connection of a large motor. The connection structure comprises a first shaft with a first seam allowance installation face and a second shaft with a second seam allowance installation face, the first shaft and the second shaft are respectively machined, the first seam allowance installation face comprises a first outer edge extending outwards and a circular protrusion in the middle, the second seam allowance installation face comprises a second outer edge extending outwards and a circular sunk groove in the middle, the first outer edge and the second outer edge are evenly provided with corresponding installation holes, the first shaft with the first seam allowance installation face and the second shaft with the second seam allowance installation face are respectively machined and arranged together in a shrinkage fit mode through corresponding seam allowances and are fixed through the first seam allowance installation face and the second seam allowance installation face, and the first shaft and the second shaft become a whole shaft. The connection structure is simple in structure, good in manufacturability and reasonable; by means of the segmented shaft connection technique, new equipment is needless to be purchased again, production investment cost is greatly saved, production time is saved and production requirements are met.
Description
technical field:
The present invention relates to large motor sectional spindle linkage structure, belong to the technical field of structures of large motor.
technical background:
Along with the fast development of China's economy and electromechanics trade, increasing to the large motor demand of high pressure,, when guaranteeing quality of product, the cost of enterprise product also will constantly reduce, and also requires due date constantly to shorten simultaneously.And many powerful motors need motor with the structure of Double shaft-extension, one end shaft extension is as load end, and the other end shaft extension is used for starting electrical machinery.Existing production way is the axle processing that directly buying meets length requirement, but often the manufacturing limit of producer's existing equipment cannot be processed this type of major axis, if special buying can meet the lathe etc. of its processing for this reason, input cost is very large so, and the cycle is long again, waste resource.
Summary of the invention
The object of the invention is the problem process this type of major axis without Special Equipment for meeting, provide a kind of simple, again without the large motor sectional spindle linkage structure that again drops into new equipment and process this type of major axis.
The present invention is achieved through the following technical solutions:
Large motor sectional spindle linkage structure, include and machine separately and with the axle one of seam attachment face one with the axle two of seam attachment face two, it is characterized in that: described seam attachment face one includes the circular protrusion that outward extending outer edge one and middle part are provided with, seam attachment face two includes the circular deep gouge that outward extending outer edge two and middle part are provided with, outer edge one is evenly provided with corresponding mounting hole with on outer edge two, to machine separately and utilize together with its seam hot jacket and by seam attachment face one with the axle one of seam attachment face one and axle two with seam attachment face two, two are fixed, make axle one and axle two become an integral shaft.
Described large motor sectional spindle linkage structure, is characterized in that: described circular protrusion and circular deep gouge are interference fit.
Described large motor sectional spindle linkage structure, it is characterized in that: described axle one together with axle two hot jackets afterwards by respective bolt penetrating mounting holes and screw nut and fixed, wherein between bolt and mounting hole, be provided with bullet pad one, between nut and mounting hole, be provided with bullet pad two, plain cushion.
Advantage of the present invention is:
The present invention is simple in structure, good manufacturability, rationally; Utilize segmentation spindle technology, without again purchasing specially new equipment, greatly saved production input cost, and saved the production time, met again the needs of producing.
accompanying drawing explanation:
Fig. 1 is overall structure schematic diagram of the present invention.
Fig. 2 is axle one schematic diagram of the present invention.
Fig. 3 is axle two schematic diagram of the present invention.
embodiment:
Below in conjunction with concrete view, the present invention is illustrated.
As shown in Figure 1, large motor sectional spindle linkage structure, include and machine separately and with the axle 1 of seam attachment face 3 with the axle 2 of seam attachment face 4, seam attachment face 3 includes the circular protrusion 3.2 that outward extending outer edge 3.1 and middle part are provided with, seam attachment face 4 includes the circular deep gouge 4.2 that outward extending outer edge 4.1 and middle part are provided with, circular protrusion 3.2 is interference fit with circular deep gouge 4.2, outer edge 3.1 is evenly provided with corresponding mounting hole 5 with on outer edge 4.1, to machine separately and utilize together with its seam hot jacket and by seam attachment face 3 with the axle 1 of seam attachment face 3 and axle 2 with seam attachment face 4, 4 are fixed, make axle 1 and axle 2 become an integral shaft.
