The utility model provides a material conveying roller axle, includes the axle center, and two bearings are installed to the symmetry on the axle center, and the top cover of bearing is equipped with the axle sleeve, and bearing and axle sleeve contact each other install the shock pad between two bearings, the upper end and the axle sleeve interconnect of shock pad, the lower extreme and the axle center interconnect of shock pad.
As a further aspect of the present invention: the axis is provided with a protective sleeve.
As a further aspect of the present invention: the left side and the right side of the shaft sleeve are both provided with outer covers.
As a further aspect of the present invention: the outer edge of both ends is moulded to have the external screw thread about the axle sleeve, and the inboard shaping of enclosing cover has the internal thread, and enclosing cover and the mutual screw-thread fit of axle sleeve.
As a further aspect of the present invention: the shaping of center department of enclosing cover has the round hole, and the diameter of round hole is greater than the diameter of lag, installs sealed the pad in the round hole, and the inboard of sealed pad and the outside in close contact with of lag.
As a further aspect of the present invention: the outer side of the shaft sleeve is provided with a wear-resistant anticorrosive layer.
Compared with the prior art, the beneficial effects of the utility model are that: through install the shock pad in the axle sleeve, can reduce the effort to bearing and axle center when the material of axle sleeve top is overweight, can not cause the damage to bearing and axle center.
Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
Fig. 1 is a schematic structural diagram of the present invention.
Shown in the figure: 1. an axis; 2. a bearing; 3. a shaft sleeve; 4. a shock pad; 5. a protective sleeve; 6. an outer cover; 7. an external thread; 8. an internal thread; 9. a circular hole; 10. a gasket; 11. wear-resistant anticorrosive coating.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, a material conveying roller shaft comprises a shaft center 1, two bearings 2 are symmetrically mounted on the shaft center 1, a shaft sleeve 3 is sleeved above the bearings 2, the bearings 2 are in contact with the shaft sleeve 3, a damping pad 4 is mounted between the two bearings 2, the upper end of the damping pad 4 is connected with the shaft sleeve 3, and the lower end of the damping pad 4 is connected with the shaft center 1. Through installing shock pad 4 in axle sleeve 3, can reduce the effort to bearing 2 and axle center 1 when the material of axle sleeve 3 top is overweight, can not cause the damage to bearing 2 and axle center 1.
As a further aspect of the present invention: the shaft center 1 is provided with a protective sleeve 5. The protective sleeve 5 is used for protecting the shaft center 1.
As a further aspect of the present invention: the outer covers 6 are mounted on the left side and the right side of the shaft sleeve 3. The outer cover 6 can protect the bearing 2, and prevents impurities from being carried out inside the bearing 2, so that the bearing 2 is damaged.
As a further aspect of the present invention: the outer edge shaping at both ends has external screw thread 7 about axle sleeve 3, and the inboard shaping of enclosing cover 6 has internal thread 8, and enclosing cover 6 and the mutual screw-thread fit of axle sleeve 3.
As a further aspect of the present invention: the shaping of the center department of enclosing cover 6 has round hole 9, and the diameter of round hole 9 is greater than the diameter of lag 5, installs sealed the pad 10 in the round hole 9, and the inboard of sealed pad 10 and the outside in close contact with of lag 5.
As a further aspect of the present invention: the outer side of the shaft sleeve 3 is provided with a wear-resistant anticorrosive layer 11.
The utility model discloses a theory of operation is: by installing the damping pad 4 in the shaft sleeve 3, when the material above the shaft sleeve 3 is too heavy, the acting force on the bearing 2 and the shaft center 1 can be reduced, and the bearing 2 and the shaft center 1 cannot be damaged; the outer cover 6 can protect the bearing 2, and prevents impurities from being carried out inside the bearing 2, so that the bearing 2 is damaged.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
