Preferably, the bearing positioning step is a circular ring with a notch, the arc length of the notch is about 1-5 cm, and the length of the notch can be set according to the diameter of the cylinder. The gap on the bearing step of the roller enables the rest outer ring of the broken bearing or the clamped bearing to be exposed on one side surface, after the nut and the roller shaft are removed, the bearing outer ring or the bearing at the point is hit by an iron rod, and the bearing outer ring or the bearing at the point is easy to knock out due to the force application point.

Preferably, the bearing ejector block and the bearing outer ring are both made of hard plastics; the structure of the bearing is the structure of a common leather bearing.

Preferably, the diameter of the first fixing nut is smaller than that of the bearing rolling ring and larger than that of the bearing hole, and the first fixing nut is used for fixing the bearing in the cylinder; the second fixing nut is arranged on the outer end face of the fixing plate and used for fixing the whole roller.

Preferably, the cylinder has a diameter of 2-30 cm, is a hollow cylinder, has no limitation on length, and can be customized according to the requirements of mechanical equipment used.

Drawings

In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings needed to be used in the description of the embodiments will be briefly introduced below, and it is obvious that the drawings in the following description are only preferred embodiments of the present invention, and it is obvious for those skilled in the art that other drawings can be obtained according to these drawings without inventive effort.

FIG. 1 is a roller and bearing diagram of an embodiment of the present invention;

FIG. 2 is a view of a bearing orienting step of a roller according to an embodiment of the present invention;

the reference numbers in the figures are: 1-cylinder, 2-bearing orientation step, 3-solid layer, 4-roll shaft, 5-bearing, 6-bearing top block, 7-rectangular groove, 8-first fixing nut, 9-fixing plate, 10-second fixing nut and 11-bearing orientation step gap.

Detailed Description

Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Other advantages and effects of the present invention will be readily apparent to those skilled in the art from the disclosure herein.

The invention is further illustrated by the following examples in conjunction with the accompanying drawings:

the roller convenient for bearing replacement as shown in fig. 1 and 2 comprises a roller body 1, a bearing orientation step 2, a solid layer 3, a roller shaft 4, a bearing 5, a first fixing nut 8, a second fixing nut 10 and a fixing plate 9. The hollow cylinder body 1 is provided with a roll shaft through hole, the diameter of the roll shaft through hole is slightly smaller than that of the bearing 5, and the bearing 5 is embedded into the hollow cylinder body 1. The bearing directional step 2 extends outwards from the barrel 1 to form a solid layer 3, the solid layer 3 is provided with a rectangular groove 7 matched with the bearing top block 6, the rotation of the outer ring of the bearing 5 drives the barrel 1 to rotate, and the outer ring of the bearing 5 is leather. Bearing orientation step 2 is located between barrel 1 and bearing 5, makes bearing 5 unilateral stopped to remove, and bearing orientation step 2 department has a breach 11, and breach 11 is as dismantling bearing 5 or the fulcrum of the outer lane that cracked bearing 5 left over, and the bearing 5 or the bearing outer lane that remains after cracked is changed to convenient to dismantle. The roller shaft 4 passes through the inside of the bearing 5, the inside of the cylinder 1 and the fixing plate 9. The bearing 5 is fixed inside the barrel 1 through the first fixing nut 8, meanwhile, the diameter of the first fixing nut 8 is larger than the diameter of the inner ring of the bearing 5 and smaller than the diameter of the outer ring of the bearing, and then the shaft is fixed on the fixing plate 9 through the second fixing nut 10.

In order to fix the roller better and ensure that the bearing 5 is fixed in the through hole of the roller shaft 4 and does not move back and forth in the cylinder 1 or move on the roller shaft 4, bearing orientation steps 2 are arranged at two ends of the cylinder 1 and first fixing nuts 8 are arranged.

In order to facilitate the disassembly and the replacement of the bearing 5, the roller shaft 4 can be drawn out by disassembling the first and second fixed nuts, and is not fixed in the barrel body 1 or fixed on an instrument device, after the roller shaft 4 is disassembled, the residual bearing 5 and the barrel body 1 are knocked out by using an iron rod to knock the notch 11 on the bearing directional step 2, so that the bearing 5 or the left bearing outer ring can be knocked out.

The length and the diameter of the cylinder body 1 are not limited, so that the application range of the cylinder body can be expanded as required; the cylinder 1 is a hollow cylinder 1, and knocking out the bearing 5 through one end of the cylinder 1 becomes another method for detaching the bearing 5.

The above description is only a preferred example of the present invention, and the technical solution of the present invention is not limited thereto, and it should be noted that for those skilled in the art, under the teaching provided by the present invention, other equivalent variations and modifications can be made as common general knowledge in the field, and the protection scope of the present invention should also be considered.
