Description
Technical field
The present invention relates to a kind of bearing, the taper roll bearing with detachable roller is related particularly to, for steel
The supporting of iron industry rolling mill roll, belongs to field of bearings.
Background technology
Traditional taper roll bearing is limited by this body structure, the gap very little after assembling between roller and roller, and
There is retainer to block, therefore, it is difficult to be clearly observed the abrasion condition of inner ring raceway, so, can not just go out in raceway
Found in time before existing fatigue flake and more renew bearing, often raceway delamination damage, occur seizing, off-axis etc. seriously after
Fruit causes equipment downtime just passively to carry out bearing replacing, substantially increases maintenance cost.
The content of the invention
In view of above-mentioned technological deficiency, it is an object of the invention to provide the taper roller axle with detachable roller
Hold, the abrasion condition of early detection bearing is capable of by detachable roller structure, reduce the equipment caused by bearing damage
Failure and maintenance cost increase.
To achieve these goals, the technical solution adopted in the present invention is：Taper roller with detachable roller
Bearing, it is characterised in that including outer ring, inner ring, retainer, hollow roller, bearing pin, retainer large washer, retainer small washer and
Split pin；Hollow roller is arranged in retainer plurality of pockets, retainer be arranged between inner ring and outer ring, retainer external diameter with
Raceway contact in bearing outer ring, retainer internal diameter and bearing inner race external diameter raceway contact, described roller axle center are cylindric sky
Core structure, bearing pin is penetrated in hollow roller, and one end is connected by screw thread with retainer large washer, and the other end is small through retainer
Packing ring is simultaneously provided with split pin on the bearing pin close to retainer small washer.
Described roller axle center inflated diameter is engaged with pin diameter.
During equipment conventional maintenance, split pin can be opened, then pull down bearing pin and hollow roller, in the space vacateed
Observe the abrasion condition of inner ring raceway.
The beneficial effects of the invention are as follows：The present invention is simple in construction, easy to operate, being capable of early stage by detachable roller structure
It was found that the abrasion condition of bearing, reduces the equipment fault and maintenance cost increase caused by bearing damage.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
In figure, 1, outer ring, 2, inner ring, 3, hollow roller, 4, bearing pin, 5, retainer large washer, 6, retainer small washer, 7,

Embodiment
The present invention is described in detail below in conjunction with the accompanying drawings.
As shown in figure 1, the taper roll bearing with detachable roller, it is characterised in that including outer ring 1, inner ring 2, protect
Hold frame, hollow roller 3, bearing pin 4, retainer large washer 5, retainer small washer 6 and split pin 7；Hollow roller 3 is arranged at holding
In frame plurality of pockets, retainer is arranged between inner ring 2 and outer ring 1, retainer external diameter and raceway contact in bearing outer ring, is kept
Frame internal diameter and the external diameter raceway contact of bearing inner race 1, described roller axle center is cylindric hollow-core construction, and bearing pin 4 is penetrated in hollow
In roller 3, one end is connected by screw thread with retainer large washer 5, and the other end is through retainer small washer 6 and close to retainer
The bearing pin 4 of small washer 6 is provided with split pin 7；During installation, bearing pin 4 passes through the axle center of hollow roller 3, and one end is by screw thread with protecting
Hold that frame large washer 5 is linked together, the other end passes through retainer small washer 5, and on the bearing pin 4 close to retainer small washer 5
Provided with split pin 7, such bearing pin 4, hollow roller 3, retainer large washer 5, retainer small washer 6 and inner ring 2 just constitute one
Component, finally constitutes a set of bearing with outer ring 1；During equipment conventional maintenance, split pin 7 can be opened, then pull down bearing pin 4 and sky
Heart roller 3, in the space the vacateed i.e. abrasion condition of observable inner ring raceway.
