Problems solved by technology
[0002] At present, the sliding bearings in the speed change mechanism of the double-speed variable speed coiler are generally lubricated by thin oil spraying. And the oil groove on the end surface of the lubricating bearing enters the friction surface between the bearing and the shaft. During the working process, when the gear rotates, the lubricating oil can hardly enter the friction surface through the oil hole at the root of the tooth, and only a small amount of lubricating oil can enter the end surface of the sliding bearing. When the coiler is running at high speed, the sliding bearings are not well lubricated and cooled, and seizures often occur, resulting in serious accidents

The invention relates to a strip coiler speed change mechanism adopting a centrifugal lubrication mode. The strip coiler speed change mechanism comprises first lubricating bearings and second lubricating bearings, wherein the first lubricating bearings and the second lubricating bearings are installed on a high speed shaft at intervals, the first lubricating bearings are arranged in pairs, the second lubricating bearings are arranged in pairs, a first gear is installed on each first lubricating bearing, a second gear is installed on each second lubricating bearing, main lubricating oil holes which are axially arranged are arranged in the high speed shaft, a first branch lubricating oil hole and a second branch lubricating oil hole are also arranged in the high speed shaft, a first gap is formed between the adjacent end surfaces of the two first lubricating bearings, a second gap is formed between the adjacent end surfaces of the two second lubricating bearings, a first gear oil hole is arranged on the first gear, and a second gear oil hole is arranged on the second gear. The strip coiler speed change mechanism has artful, simple, compact and reasonable structure and convenient manufacture and installation, and can greatly improve the lubricating condition of a sliding bearing and bring the heat and the fine sundries generated by the friction of the bearing and the shaft out of a friction working surface.
Description
technical field [0001] The invention relates to a speed change mechanism of a strip coiler in the metallurgical industry, in particular to a speed change mechanism of a strip coiler adopting centrifugal lubrication. Background technique [0002] At present, the sliding bearings in the speed change mechanism of the double-speed variable speed coiler are generally lubricated by thin oil spraying. And the oil groove on the end surface of the lubricating bearing enters the friction surface between the bearing and the shaft. During the working process, when the gear rotates, the lubricating oil can hardly enter the friction surface through the oil hole at the root of the tooth, and only a small amount of lubricating oil can enter the end surface of the sliding bearing. When the coiler is running at high speed, the sliding bearings are not well lubricated and cooled, and the bite phenomenon often occurs, resulting in serious accidents.
