Abstract
The utility model relates to a spline limiting structure, which comprises an inner spline shaft and an outer spline shaft. The ends of the inner spline shaft and the outer spline shaft are provided with inner splines and outer splines by processing. The minor diameter of each outer spline is the same as the diameter of each outer spline, a limit ring is disposed at the end of the inner spline shaft, and the limit ring is provided with inner teeth the same as the splines, end faces of the teeth are opposite to the tooth end faces of the outer spline shaft, and the limit ring is fixed to the inner spline shaft. By adopting the limit ring structure, the spline limiting structure is smart in design, and space is saved greatly while axial and peripheral positioning of the spline shafts is realized.
Description
Technical field
The utility model has related to a kind of limit structure, especially a kind of spline limit structure.
Background technique
In the existing mechanical transmission, it is the Placement of very general a kind of transferring power that spline connects, for the spacing spacing mode of common Steel Cable Baffle Ring that normally adopts of splined shaft.The transmitted power of the machinery that has at present is increasing, and common Steel Cable Baffle Ring is spacing can not to satisfy usage requirement, because the restriction in space, limit methods such as the nut of simplicity of design also can't be realized needed function.
Summary of the invention
The utility model provides a kind of simplicity of design, satisfies the spline limit structure of the usage requirement of high-power transmission.
The technical solution of the utility model is: structure comprises female splined shaft and male splined shaft, and its end is processed with internal spline and external splines respectively; The path of described external splines is identical with the male splined shaft diameter, and the end of female splined shaft is provided with limited ring, and the tooth identical with spline is set in the described limited ring, and the end face of described tooth is relative with the increment face of male splined shaft, and limited ring and female splined shaft are fixed.Described limited ring is provided with boss, and the female splined shaft end is provided with groove and matches with described boss.The arranged outside of described limited ring has collar, is fixed with screw on the female splined shaft, and the spiral shell of screw emits the inboard to be provided with annular groove, and described collar is stuck in the described annular groove.
The utility model earlier passes the limited ring cover tooth of rotation behind the external splines when mounted, and at this moment limited ring increment face is relative with transmission shaft external spline teeth end face, and limited ring is fixed with female splined shaft simultaneously, has realized axial limiting and circumferential the location; Described limited ring and female splined shaft are fixed, can adopt and boss is set on limited ring and matches with the groove of internal spline axle head and to adopt the limited ring structure, design ingeniously, in the axial and circumferential of having realized splined shaft spacing, saved the space greatly.
