Abstract
The utility model discloses a segmented connecting shaft connecting structure of a large motor. The segmented connecting shaft connecting structure of the large motor comprises a first shaft and a second shaft which are machined respectively, wherein the first shaft is provided with a first spigot installation face; the second shaft is provided with a second spigot installation face; the first spigot installation face is provided with a first outer edge extending outwards and a circular protrusion in the middle; the second spigot installation face is provided with a second outer edge extending outwards and a circular countersink groove in the middle; the first outer edge and the second outer edge are evenly provided with corresponding installing holes; the first shaft and the second shaft which are machined respectively and are provided with the first spigot installation face and the second spigot installation face respectively are thermally arranged together in a sleeved mode through spigots and are fixed through the first spigot installation face and the second spigot installation face, so that the first shaft and the second shaft are integrated. The segmented connecting shaft connecting structure of the large motor is simple in structure, good in manufacturability and reasonable, the segmented connecting shaft technology is utilized, it is unnecessary to repurchase new equipment specially, production investment cost is largely saved, production time is saved, and production requirements are met.
Description
technical field:
The utility model relates to large motor sectional spindle linkage structure, belongs 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,, in 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 the structure of motor with 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.
Model utility content
The purpose of this utility model is the problem of processing this type of major axis without Special Equipment for meeting, and provides 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 utility model 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, by machine separately and utilize its seam hot jacket with the axle one of seam attachment face one with the axle two with seam attachment face two together with and by seam attachment face one, 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.
The utility model has the advantages that:
The utility model 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 utility model.
Fig. 2 is axle one schematic diagram of the present utility model.
Fig. 3 is axle two schematic diagram of the present utility model.
embodiment:
Below in conjunction with concrete view, the utility model 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, by machine separately and utilize its seam hot jacket with the axle 1 of seam attachment face 3 with the axle 2 with seam attachment face 4 together with and by seam attachment face 3, 4 are fixed, make axle 1 and axle 2 become an integral shaft.
