Abstract
The invention relates to a bearing, and in particular relates to a conical roller bearing with a detachable type roller, which is used for supporting a rolling mill roller of iron and steel industry and belongs to the field of bearings. Hollow rollers are arranged in a plurality of pocket holes of a retainer; the retainer is mounted between an inner ring and an outer ring; the outer diameter of the retainer is in contact with a roller path in the outer ring of the bearing; the inner diameter of the retainer is in contact with a roller path on the outer diameter of the inner ring of the bearing; the axis of the roller is in a cylindrical hollow structure; a pin shaft penetrates into the hollow roller; one end of the pin shaft is connected with a large gasket of the retainer by a thread; and the other end of the pin shaft penetrates through a small gasket of the retainer and a cotter pin is arranged on the pin shaft close to the small gasket of the retainer. The conical roller bearing with the detachable type roller has a simple structure and is convenient to operate; an abrasion condition of the bearing can be found early through the detachable type roller structure; and equipment faults caused by the fact that the bearing is damaged, and the increasing of the maintenance cost are reduced.
Description
Technical field
The present invention relates to a kind of bearing, particularly relate to the tapered roller bearing with detachable roller, for the supporting of steel industry rolling mill roll, belong to field of bearings.
Background technique
Traditional tapered roller bearing limit due to this body structure; gap after assembling between roller and roller is very little; and have retainer to block; therefore; be difficult to the abrasion condition clearly observing inner ring raceway, like this, just before fatigue flake appears in bearing race, also more cannot renew bearing by Timeliness coverage; be usually bearing race delamination damage, occur that the serious consequence such as seize, off-axis causes that equipment downtime is just passive carries out bearing replacing, substantially increases maintenance cost.
Summary of the invention
In view of the technological deficiency of above-mentioned existence, the object of this invention is to provide the tapered roller bearing with detachable roller, can the abrasion condition of early detection bearing by detachable roller structure, reduce equipment failure because bearing damage causes and maintenance cost increases.
To achieve these goals, the technical solution adopted in the present invention is: the tapered roller bearing with detachable roller, it is characterized in that comprising outer ring, inner ring, retainer, hollow roller, bearing pin, retainer large washer, retainer small washer and cotter pin; Hollow roller is arranged in the some pocket holes of retainer, retainer is arranged between inner ring and outer ring, raceway contact in retainer external diameter and bearing outer ring, retainer internal diameter and bearing inner race external diameter raceway contact, described roller axle center is cylindric hollow-core construction, bearing pin penetrates in hollow roller, and one end is connected with retainer large washer by screw thread, and the other end passes retainer small washer and be provided with cotter pin on the bearing pin near retainer small washer.
Described roller axle center inflated diameter matches with pin diameter.
During equipment conventional maintenance, cotter pin can be opened, then pull down bearing pin and hollow roller, at the abrasion condition of the space vacateed and observable inner ring raceway.
The invention has the beneficial effects as follows: structure of the present invention is simple, easy to operate, can the abrasion condition of early detection bearing by detachable roller structure, reduce equipment failure because bearing damage causes and maintenance cost increases.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, 1, outer ring, 2, inner ring, 3, hollow roller, 4, bearing pin, 5, retainer large washer, 6, retainer small washer, 7, cotter pin.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
As shown in Figure 1, there is the tapered roller bearing of detachable roller, it is characterized in that comprising outer ring 1, inner ring 2, retainer, hollow roller 3, bearing pin 4, retainer large washer 5, retainer small washer 6 and cotter pin 7; Hollow roller 3 is arranged in the some pocket holes of retainer, retainer is arranged between inner ring 2 and outer ring 1, raceway contact in retainer external diameter and bearing outer ring, retainer internal diameter and bearing inner race 1 external diameter raceway contact, described roller axle center is cylindric hollow-core construction, bearing pin 4 penetrates in hollow roller 3, and one end is connected with retainer large washer 5 by screw thread, and the other end passes retainer small washer 6 and be provided with cotter pin 7 on the bearing pin 4 near retainer small washer 6; During installation, bearing pin 4 is through the axle center of hollow roller 3, one end is linked together by screw thread and retainer large washer 5, the other end passes retainer small washer 5, and cotter pin 7 is provided with on the bearing pin 4 near retainer small washer 5, such bearing pin 4, hollow roller 3, retainer large washer 5, retainer small washer 6 and inner ring 2 be a composition assembly just, and last and outer ring 1 forms a set of bearing; During equipment conventional maintenance, cotter pin 7 can be opened, then pull down bearing pin 4 and hollow roller 3, at the abrasion condition of the space vacateed and observable inner ring raceway.
