Abstract
Description
Technical Field
[0001] The utility model belongs to the field of lubrication devices, in particular to a novel self-lubricating device for a pinch roller device. Background Art
[0002] The pinch roll assembly is a crucial piece of equipment on a steel rolling line, used in the three-way intersection of the strip. During actual use, the free roll and the active roll of the pinch roll assembly form a roll gap of a certain size based on the thickness of the strip being produced. The active roll rotates, pinching the strip and transporting it to the flat conveyor chain. The pinch roll assembly uses a large amount of cooling water, so after prolonged use, the seals of the equipment will wear, causing water to enter the gearbox under the active roll. Because the gearbox is located below the cover plate in the three-way intersection, water ingress cannot be detected in time, and the oil in the gearbox will circulate again, causing the oil in the lubrication station to be contaminated by the water. Consequently, the entire lubrication station needs to be replaced with new oil, resulting in a waste of manpower, material resources, and time. Utility Model Content
