Problems solved by technology
During the conveying process, the belt between the two rollers is deformed due to the gravity of the material, and the deformed and sagging belt will be scratched soon under the action of the corners and friction at the end of the rollers, resulting in cracked and had to be scrapped
Replacing a new belt not only increases the production cost, but also increases the maintenance time, which affects the smooth progress of production

Embodiment Construction
[0014] The invention is composed of idler shaft 1, end cover 2, idler shaft bearing 6, wear-resistant bushing 4, steel cylinder 5 and rolling bearing 3.
[0015] As shown in the figure, the end cover 2 is installed at both ends of the idler shaft 1, the idler shaft bearing 6 is installed between the idler shaft 1 and the end cover 2, and a steel cylinder 5 is installed between the upper parts of the end cover 2 at both ends. The structure of this part is the same as the existing rubber idler, and the existing rubber idler can be used, or the waste or discarded rubber idler can be used to remove the rubber body.
[0016] As shown in the figure, a wear-resistant bushing 4 is set on the outer circumference of the steel cylinder 5, and a rolling bearing 3 is installed between the wear-resistant bushing 4 and the end cover 2. The outer circumference of the rolling bearing 3 is higher than the outer circumference of the end covers 2 at both ends. The outer peripheral surface of the ...

The invention provides a belt carrier roller capable of preventing a belt from being scratched and belongs to the technical field of belt transportation equipment. The belt carrier roller capable of preventing the belt from being scratched is used for preventing the belt from being scratched. The technical scheme includes that the belt carrier roller capable of preventing the belt from being scratched comprises a carrier roller shaft, end covers, a carrier roller shaft bearing and a steel cylinder, a wear-resistant shaft sleeve is sleeved on the periphery of the steel cylinder, rolling bearings are installed between the wear-resistant shaft sleeve and the end covers, the outer circumference of each rolling bearing is higher than the outer circumferences of the end covers which are arranged at two ends of all rolling bearing, and the outer circumferential surface of the wear-resistant bearing sleeve is in the same plane with the outer circumferential surface of each rolling bearing. Due to the fact that the wear-resistant shaft sleeve and the rolling bearings are installed outside the steel cylinder of the carrier roller and the rolling bearings contacting with the belt are arranged, friction on the belt is reduced, the belt is effectively protected from being scratched by edges of the existing carrier roller, and the belt is further prevented from being directly scratched when the carrier roller shaft bearing is damaged. The belt carrier roller capable of preventing the belt from being scratched has the advantages of being simple in structure, flexible in operation, small in friction resistance, capable of being improved by using the existing rubber carrier roller, not only reducing cost, but also enabling service life to be more than ten times that of the existing carrier roller, obvious in economic benefit and capable of having promotional value.
Description
technical field [0001] The invention relates to a belt idler used for belt transportation, and belongs to the technical field of belt transportation equipment. Background technique [0002] Belt conveying is an important way for modern factories to transport raw materials or products. Large and medium-sized belt conveyors include left idlers, right idlers and horizontal idlers to form a moving frame. The weight of the material carried by the belt is borne by the left idler, the horizontal idler and the right idler, and each of the three idlers rotates around its own rolling bearing. During the conveying process, the belt between the two rollers is deformed due to the gravity of the material, and the deformed and sagging belt will be scratched soon under the action of the corners and friction at the end of the rollers, resulting in Cracked and had to be scrapped. Replacing a new belt not only increases the production cost, but also increases the maintenance time, which affe...
