The cross section of the connection section of a driving shaft and a driven shaft is hexagonal in shape, the cross section of the inner hole of a cylindrical shaft sleeve is matched with the driving shaft and the driven shaft in shape and the shaft sleeve is sleeved outside the driving shaft and the driven shaft, the two ends of the shaft sleeve are provided with sealing rings, one side of the driven shaft is provided with a back-up ring, and the thickness of the back-up ring is matched with the distance from the shaft sleeve to a driven bearing. The high-rotating-speed and small-shaft-diameter shaft coupling can work stably in a high rotation speed, facilities assembling and positioning, and the coaxiality of the driving shaft and the driven shaft can be guaranteed. And meanwhile, the high-rotating-speed and small-shaft-diameter shaft coupling has the advantages of simple structure, simple installation, easy machining, low cost, and high reliability.
Description
Technical field
The utility model relates to a kind of mechanical high rotating speed small axle diameter coupling technology, specially refers to a kind of high rotating speed small axle diameter coupling.
Background technique
In the mechanical transmission of some high-tech area, the rotating speed of working shaft is generally all very high, conventionally in 100000r/min left and right.And in some application, the diameter of driving shaft and driven shaft is also little, be generally 5mm left and right.When needs are connected driving shaft and when transferring power, master and slave moving axis need to be connected with driven shaft.Prior art adopts spline joint conventionally, on master and slave moving axis, processes spline, adopts spline housing that master and slave moving axis is linked together.Because the diameter of master and slave moving axis is less, not only process comparatively difficulty of spline, and the dimensional accuracy of spline is difficult to ensure card, connect precision and be difficult to guarantee.Obviously, the high rotating speed small axle diameter of prior art coupling structure exists comparatively difficulty of processing, and dimensional accuracy is difficult to ensure card and is connected precision and is difficult to the problems such as assurance.
Summary of the invention
The comparatively difficulty of processing existing for solving prior art high rotating speed small axle diameter coupling structure, dimensional accuracy is difficult to ensure card and is connected precision and is difficult to the problems such as assurance, the utility model proposes a kind of high rotating speed small axle diameter coupling.The high rotating speed small axle diameter of the utility model coupling, the shape of cross section of master and slave moving axis linkage section is regular hexagon, profile is that columniform inner hole of shaft sleeve shape of cross section and master and slave moving axis match and be sleeved on outside master and slave moving axis, be provided with seal ring at axle sleeve two ends, be provided with back-up ring in driven shaft one side, the thickness of its back-up ring and axle sleeve match to the distance of driven bearing.
Further technological scheme is, described high rotating speed small axle diameter coupling adopts hard metal (preferred, described hard metal is stainless steel) to make.
Thereby adopt brass material to make the deficiency that does not reach hardness requirement by adopting hard metal to overcome high rotating speed small axle diameter coupling, adopt hard metal to regulate hardness by heat treatment, thereby reach the hardness requirement of course of working.
The useful technique effect of the high rotating speed small axle diameter of the utility model coupling be can stable operation under high rotating speed, be convenient to assembling and location, the coaxality of master and slave moving axis is guaranteed.Meanwhile, also there is simple in structure, simple installation, be easy to processing, the advantage such as cheap, good reliability.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of the high rotating speed small axle diameter of the utility model coupling;
Below in conjunction with the drawings and specific embodiments, the high rotating speed small axle diameter of the utility model coupling is further described.
Embodiment
Accompanying drawing 1 is the structural representation of the high rotating speed small axle diameter of the utility model coupling, and accompanying drawing 2 is A-A sectional structure schematic diagram of accompanying drawing 1, and in figure, l is driving shaft, and 2 is axle sleeve, and 3 is driven shaft, and 4 is back-up ring, and 5 is seal ring, and 6 is driven bearing.As seen from the figure, the high rotating speed small axle diameter of the utility model coupling, main, driven shaft (1, 3) shape of cross section of linkage section is regular hexagon, profile is columniform axle sleeve 2 endoporus shape of cross section and masters, driven shaft matches and is sleeved on master, driven shaft (1, 3) outside, be provided with seal ring 5 at axle sleeve 2 two ends, be provided with back-up ring 4 in driven shaft one side, by being set, back-up ring 4 is conducive to coupling to position, if coupling only depends on seal ring 5 to carry out axially locating, when High Rotation Speed, will wear and tear because seal ring 5 appears in the axial motion of axle sleeve 2, thereby after generation residue, also may alter to driven bearing 6, affect the normal work of driven bearing 6 and cause occurring accident, back-up ring 4 also plays and stops seal ring 5 residues to enter driven bearing 6 simultaneously, thereby guarantee the safety of working procedure, the thickness of its back-up ring 4 and axle sleeve 2 match to the distance of driven bearing 6.The shape of cross section of the master and slave moving axis linkage section of the high rotating speed small axle diameter of the utility model coupling is regular hexagon, with respect to processing spline, makes it be easy to processing, cheap, particularly all the more so to the less axle of diameter.Due to orthohexagonal simple in structure, make its processing comparatively easy, machining accuracy is higher, is convenient to assembling and location, simple installation, has effectively guaranteed the coaxality of master and slave moving axis, can stable operation under high rotating speed, and there is higher reliability.
Obviously, the useful technique effect of the high rotating speed small axle diameter of the utility model coupling be can stable operation under high rotating speed, the coaxality of master and slave moving axis is guaranteed.Meanwhile, also there is simple in structure, simple installation, be easy to processing, the advantage such as cheap, good reliability.
