Description

Technical Field

[0001] The utility model relates to the technical field of rollers, in particular to a self-lubricating wear-resistant roller. Background Art

[0002] Rollers are an important component of belt conveyors. Existing rollers are mainly composed of a shell, a supporting shaft, a bearing and a bearing seat. Grease is added to the bearings when the rollers are manufactured. Grease cannot be added to the bearings during the use of the rollers, which is a one-time grease filling method.

[0003] Existing self-lubricating wear-resistant rollers, such as the self-lubricating wear-resistant roller disclosed in the utility model patent with application number 202121035396.5, have a main structure including a roller shaft rotatably inserted into the roller body, a bearing fixedly installed on the roller body and sleeved on the outside of the roller shaft, an oil storage barrel fixedly installed inside the roller body, a fixed shaft fixedly installed in the oil storage barrel, a piston slidingly sleeved on the fixed shaft and slidably embedded in the oil storage barrel, a connecting pipe fixedly connected to the bottom of the oil storage barrel and its outer end is connected to the inner side of the bearing of the roller body, and an oil injection structure is installed on the roller body. When in use, the passive rotation of the roller body drives the oil storage barrel to rotate, and then drives the fixed shaft and the piston on the fixed shaft to rotate. Since the density of the piston is greater than the density of the lubricating oil, the piston always tends to move to the bottom of the oil storage barrel under the centrifugal action of the piston. When the outer oil seal and the inner oil seal on the roller body and the bearing are damaged and leak, the oil in the oil storage barrel is injected into the bearing through the connecting pipe under the action of the piston, thereby realizing emergency lubrication of the bearing and preventing bearing wear and damage. When the lubricating oil in the oil storage barrel is used up, lubricating oil can be added through the oil injection structure.

[0004] However, most existing rollers have poor sealing mechanisms, which can easily allow dust to enter the bearings and affect lubrication. In addition, after long-term use, the rollers can easily become hot, affecting the service life of the device. Utility Model Content
