CN203374625U - Axial and radial bidirectional limiting structure for shaft - Google Patents

Abstract

The utility model discloses an axial and radial bidirectional limiting structure for a shaft. The axial and radial bidirectional limiting structure for the shaft is characterized by comprising an axial limiting piece and a radial limiting piece, wherein the axial limiting piece is arranged outside the end of the shaft; the radial limiting piece is arranged along the outer circumferential surface of the shaft. The axial and radial bidirectional limiting structure for the shaft has the advantages that the shaft is limited in the axial direction and the radial direction; the axial movement and the radial rotation of the shaft are prevented; the shaft is limited effectively; the end of the shaft is protected; damage is reduced; the axial and radial bidirectional limiting structure for the shaft is detached conveniently and quickly.

Description

Axial and the radially bidirectionally limited structure of axle

Technical field

The utility model relates to a kind of axial and radially bidirectionally limited structure of axle.

Background technique

Axle is to be through in the middle of bearing or the cylindrical object that wheel is middle or gear is middle.Axle is supporting rotational parts the mechanical parts that turn round therewith to transmit motion, moment of torsion or moment of flexure, and the part of doing rotation motion in machine just is contained on axle.Axle is when spacing, and the axially easy play of axle self, radially easily rotate, and dismantle loaded down with trivial details.

Therefore, be badly in need of a kind of improved technology and solve existing this problem in prior art.

The model utility content

The purpose of this utility model is to provide a kind of axial and radially bidirectionally limited structure of axle.

The technical solution adopted in the utility model is:

Axle axially and radially bidirectionally limited structure, it is characterized in that: comprise axial limiting part and bounding means radially, described axial limiting part is located at outside shaft end, and described radially bounding means is along the outer peripheral surface setting of axle.

Described radially bounding means arranges along the outer semicircle side face of axle.

The utility model has the advantages that: to axle axially and radially bidirectionally limited, prevent axle self axial float and radial rotary, the effective location axle, the protection axle head, reduce impaired, and dismantle convenient.

The accompanying drawing explanation

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

Fig. 1 is structural representation of the present utility model.

Fig. 2 is worm's eye view of the present utility model.

Fig. 3 is side view of the present utility model.

Wherein: 1, axial limiting part, 2, bounding means radially, 3, axle.

Embodiment

As Figure 1-3; axial and the radially bidirectionally limited structure of axle of the present utility model; comprise axial limiting part 1 and bounding means 2 radially, described axial limiting part 1 is located at axle 3 outsides, ends, and described radially bounding means 2 arranges along the outer semicircle side face of axle 3; to axle 3 axially and radially bidirectionally limited; prevent axle 3 self axial float and radial rotary, effective location axle 3, protection axle head; reduce impaired, and dismantle convenient.

Axial limiting part 1 is similar to hole back-up ring structure, the axial float of restrictive axes 3; Radially bounding means 2 is clamping devices, by the bolt stationary axle 3 of take-uping the slack, prevents that axle 3 from rotating.This structure can reduce because the error that bring in the gap of axle, for the axle of special substance, also reaches the protection axle head, reduces impaired; This structure is the side stationary axle, just can the easy removal axle as long as dismantle radially bounding means in when dismounting, and simple structure is located and is played effective effect axle.

Claims (2)

1. Axle axially and radially bidirectionally limited structure, it is characterized in that: comprise axial limiting part and bounding means radially, described axial limiting part is located at outside shaft end, and described radially bounding means is along the outer peripheral surface setting of axle.
2. Axle according to claim 1 axially and radially bidirectionally limited structure, it is characterized in that: described radially bounding means arranges along the outer semicircle side face of axle.
