Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipe winch technology, specifically an integrated welded pipe winch bearing oil baffle ring. Background Technology
[0002] A pipe winch is a type of mechanical equipment used in specific operating environments and is widely used in shipbuilding, marine engineering, and other fields. Pipe winches are mainly used for winding, storing, and releasing pipes or hoses to adapt to different operational needs. On ships, pipe winches are often used for mooring, towing, and anchor chain retrieval. In marine engineering, pipe winches are more often used in crude oil export systems and pipelaying operations, such as hose winches used on offshore structures like floating production storage and offloading (FPSO) units and mobile platforms, as well as pipelaying winches used on pipelaying vessels for operations such as abandoning pipes, retrieving pipes, emergency response, and towing. Pipe winches require bearings to rotate and release the line; therefore, bearings play a crucial role in pipe winches.
[0003] The existing publication number CN2084536U discloses an improved bearing housing anti-leakage oil retainer ring. The outer circle of the oil retainer ring is added with an annular edge for interference fit and is installed on the main shaft. It fits together with the inner edge of the bearing side cover and covers the main shaft. The rotation of the main shaft drives the rolling bearing to rotate. This rotation causes the lubricating oil in the bearing housing to splash onto the oil retainer ring. Since the annular edge of the outer circle of the oil retainer ring fits together with the inner edge of the bearing side cover and covers the main shaft part between the oil retainer ring and the bearing side cover, the problem of lubricating oil flowing out along the shaft is prevented.
[0004] Currently, the oil retainers on winches are manufactured as a single piece of cast iron. During this process, the appropriate size oil retainer is selected based on the bearing's dimensions and external structure. The manufacturing process involves cutting the cast iron material, calculating the required quantity based on the bearing's design drawings, and then using tools like a saw to divide the large cast iron blank into smaller pieces before machining them into the final oil retainer. This process of cutting the cast iron material results in material loss and resource waste. Furthermore, the manufacturing process requires individual cutting, sawing, and shaping, making it quite cumbersome.
[0005] Therefore, those skilled in the art have provided an integrated welded winch bearing oil baffle ring to solve the problems mentioned in the background art. Utility Model Content
