Abstract
The utility model discloses a combined type axial positioning structure for a part on a shaft and belongs to the technical field of axial positioning. The part on the shaft is sheathed on the shaft, and the shaft is provided with a clamping ring groove which is internally provided with a clamping ring in a clamping manner; one end of the part on the shaft is provided with a spigot, and the clamping ring is limited in the spigot and is positioned by the spigot and the clamping ring groove; the other end of the part on the shaft is connected with a pressing sleeve and a blocking ring; the pressing sleeve is positioned between the blocking ring and the part on the shaft; the pressing sleeve and the blocking ring are sheathed on the shaft in a manner of matching of cold shrinkage and deformation; and the blocking ring is positioned in a blocking ring groove on the shaft. The combined type axial positioning structure disclosed by the utility model has the characteristics of simple structure and process, economy, safety and reliability and the like, is especially suitable for occasions that the axial load of the part on the shaft is large and the material of the shaft is flexible, and can save the cost of the material.
Description
Technical field
The utility model relates to a kind of parts on shaft combined type axial positioning structure, belongs to axially locating technical field.
Background technique
Part often needs its two ends to position after being sleeved on axle, prevent its axial float.Conventionally the axially locating of parts on shaft mainly adopts the modes such as the shaft shoulder, sleeve nut, back-up ring, but at some special occasions, inconvenience adopts above-mentioned position structure.For example, in order to save cost of material, on slender axles, generally avoid adopting shaft shoulder orientation type; The axle that material is softer generally avoids the mode of machining screw on axle to locate; The orientation type of back-up ring is also avoided adopting in the position that axial load is large.
Summary of the invention
Overcome the deficiencies in the prior art, the utility model provides a kind of parts on shaft combined type axial positioning structure.
For prior art above shortcomings, the purpose of this utility model is to provide a kind of simple in structure, reliable, is suitable for that parts on shaft thrust load is large, the occasion of the material softer of axle, and can save the parts on shaft combined type axial positioning structure of cost of material.
The technical solution of the utility model is achieved in that
A parts on shaft combined type axial positioning structure, parts on shaft is sleeved on axle, offers annular groove on axle, is installed with snap ring in annular groove; Parts on shaft one end offers seam, and snap ring is limited in seam, and snap ring is located by seam and annular groove; The parts on shaft the other end connects clamping sleeve and back-up ring, and clamping sleeve is between back-up ring and parts on shaft, and the mode that clamping sleeve and back-up ring coordinate with shrinkage distortion is sleeved on axle, and back-up ring is positioned at the circlip groove on axle.
Further, described snap ring is for to surround by two halves the split type snap ring forming.
The utility model is taked split type snap ring location, and the compound mode of back-up ring, clamping sleeve shrink-fit auxiliary positioning realizes the axially locating to parts on shaft.Independent snap ring can bear larger thrust load, then is equipped with clamping sleeve and the back-up ring that adopts shrink-fit, can from axle, two ends realization locate part axial.
The utlity model has the features such as structural manufacturing process is simple, economic, safe, reliable, be particularly suitable for that parts on shaft thrust load is large, the occasion of the material softer of axle, and can save cost of material.
Accompanying drawing explanation
When considered in conjunction with the accompanying drawings, by the detailed description with reference to below, can more completely understand better the utility model and easily learn wherein many advantages of following, but accompanying drawing described herein is used to provide further understanding of the present utility model, form a part of the present utility model, schematic description and description of the present utility model is used for explaining the utility model, do not form improper restriction of the present utility model, as schemed wherein:
Fig. 1 is structural representation of the present utility model.
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment
Obviously, the many modifications and variations that those skilled in the art do based on aim of the present utility model belong to protection domain of the present utility model.
Embodiment 1: as shown in Figure 1, a kind of parts on shaft combined type axial positioning structure, parts on shaft 3 is sleeved on axle 4, on axle 4, offers annular groove, is installed with snap ring 5 in annular groove.Parts on shaft 3 one end offer seam, and snap ring 5 is limited in seam, and snap ring 5 is located by seam and annular groove; Parts on shaft 3 the other ends connect clamping sleeve 2 and back-up ring 1, and clamping sleeve 2 is between back-up ring 1 and parts on shaft 3, and the mode that clamping sleeve 2 and back-up ring 1 coordinate with shrinkage distortion is sleeved on axle 4, and its guide ring is positioned at the circlip groove on axle.
Described snap ring 5 is for to surround by two halves the split type snap ring forming, and snap ring 5 positioning precisioies are high.
The utility model split type snap ring is contained on the axle of offering annular groove, and utilizes seam that the parts on shaft of Spielpassung is offered to complete fixing to snap ring, completes axial part one side location simultaneously; By and axle between adopt the clamping sleeve of shrinkage distortion and the combining form of back-up ring, realize the location to parts on shaft opposite side.
As mentioned above, embodiment of the present utility model is explained, but as long as not departing from fact inventive point of the present utility model and effect can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, within such variation is also all included in protection domain of the present utility model.
Claims (2)
1. a parts on shaft combined type axial positioning structure, is characterized in that parts on shaft is sleeved on axle, offers annular groove on axle, is installed with snap ring in annular groove; Parts on shaft one end offers seam, and snap ring is limited in seam, and snap ring is located by seam and annular groove; The parts on shaft the other end connects clamping sleeve and back-up ring, and clamping sleeve is between back-up ring and parts on shaft, and the mode that clamping sleeve and back-up ring coordinate with shrinkage distortion is sleeved on axle, and back-up ring is positioned at the circlip groove on axle.
2. a kind of parts on shaft combined type axial positioning structure according to claim 1, is characterized in that snap ring is to surround by two halves the split type snap ring forming.
