Background technique
Multistage axis equipment is essential equipment in many manufacturing enterprises, for example screw conveyor, beet washer, gives ash-pit
Deng these belong to multistage axis equipment, are typically all that (traditional pipe nipple axis is all with pipe nipple axis between each axis of multistage axis equipment
Use casting or forging, welding integral rigidity structure) and flange rigid attachment for an entirety, very because of multistage axis entire length
It is long, it is to guarantee the concentric problem of axis using supporting or suspending bearing shell in midair mostly between each segmentation to guarantee the concentricity of multistage axis,
But if lubricant effect is bad when equipment operation, will make the abrasion of bearing shell and pipe nipple axis, and multistage axis sinking degree of disturbing is caused to increase,
The concentricity of multistage axis will be affected, and when bearing shell and pipe nipple axis are seriously worn, degree of disturbing also increases therewith, multistage axis
It is being rotated with disturbing curved state, is being rigid attachment between each axis of multistage axis, connection place is without freedom degree, when long in this way, under multistage axis
It will fracture or crack at the pipe nipple axis or big shaft flange at heavy maximum position, cause equipment fault to influence production, and multistage axis is tieed up
Repair that the time is longer, the serious economic benefit for influencing enterprise.
Summary of the invention
The utility model provides a kind of spline flexibility short joint-shaft, overcomes the defects of the prior art, and can have
Effect solves multistage axis equipment and is easy to appear fracture or cracking because multistage axis sinks, and equipment fault is caused to influence production, and multistage
The problem of axis maintenance time is longer, seriously affects Business Economic Benefit.
The technical solution of the utility model is realized by following measures: the spline flexibility short joint-shaft, including a left side

Axis, the left part of left connecting shaft are evenly distributed equipped at least four for bolted through-hole, the right part diameter of right connecting shaft
Greater than left part diameter, the right part of the left part of right connecting shaft and left connecting shaft is identical splined shaft, and the right part of right connecting shaft is equipped with
Through-hole corresponding with left connecting shaft, spline housing are tubular, and the inner wall of spline housing is equipped with the flower with left connecting shaft, right connecting shaft
The corresponding keyway of key axis, the hub splines of left connecting shaft are located at the inner cavity left part of spline housing, and the splined shaft of right connecting shaft is arranged
In the inner cavity right part of spline housing.
Here is the further optimization and/or improvements to above-mentioned utility model technical solution:
Above-mentioned left connecting shaft includes terminal pad and splined shaft, and the right part of terminal pad is equipped with the stop collar concentric with terminal pad
Platform is evenly distributed in the terminal pad on the outside of limited ring dais equipped at least four for bolted through-hole, limited ring dais
Right side and the left side one of splined shaft are concentric fixed.
Above-mentioned right connecting shaft includes terminal pad and splined shaft, and the left part of terminal pad is equipped with and right connecting shaft in right connecting shaft
The concentric limited ring dais of terminal pad is evenly distributed in the terminal pad 5 on the outside of right connecting shaft limited ring dais and uses equipped at least four
In bolted through-hole, the left side of right connecting shaft limited ring dais and the right side one of right connecting shaft splined shaft are concentric fixed.
The utility model reasonable and compact in structure, it is easy to use, it is existing when by using spline housing and spline axis connection
Gap makes to avoid rigid connection between each axis of multistage axis, and the freedom degree connected between each axis is larger, reduces when multistage axis
Entirety degree of disturbing it is larger when, the bad influence of concentricity, effectively prevents the fracture of multistage axis, reduces equipment between each axis
Maintenance frequency, influence of the equipment fault to production system is reduced, to ensure the economic benefit of enterprise.
Detailed description of the invention
Attached drawing 1 is the best embodiment of the utility model schematic diagram of main cross-sectional structure.
Attached drawing 2 is that schematic perspective view is reduced in the explosion of attached drawing 1.
Attached drawing 3 is the left view enlarged structure schematic diagram of spline housing in attached drawing 1.
Coding in attached drawing is respectively as follows: 1 for spline housing, and 2 be splined shaft, and 3 be through-hole, and 4 be keyway, and 5 be terminal pad, and 6 are
Limited ring dais.
Specific embodiment
The utility model is not limited by following embodiments, can technical solution according to the present utility model and actual conditions
Determine specific embodiment.
In the present invention, for ease of description, the description of the relative positional relationship of each component is according to specification
The Butut mode of attached drawing 1 is described, such as: front, rear, top, and bottom, left and right positional relationship be according to Figure of description 1
Butut direction determine.
The utility model is further described below with reference to examples and drawings:
As shown in attached drawing 1,2,3, the spline flexibility short joint-shaft, including left connecting shaft, spline housing 1 and right connecting shaft, it is left
The left part diameter of connecting shaft is greater than right part diameter, and the right part of left connecting shaft is splined shaft 2, and the left part of left connecting shaft is evenly distributed
It is used for bolted through-hole 3 equipped at least four, the right part diameter of right connecting shaft to be greater than left part diameter, the left part of right connecting shaft
Right part with left connecting shaft is identical splined shaft 2, and the right part of right connecting shaft is equipped with through-hole 3 corresponding with left connecting shaft, flower
