Technical Field
[0001] The utility model relates to the technical field of oil seal covers, in particular to an oil seal cover with strong sealing performance. Background Art
[0002] Oil seal is a common name for general seals, which simply means the seal of lubricating oil. It is a mechanical component used to seal grease (oil is the most common liquid substance in the transmission system, and also refers to general liquid substances). It isolates the parts that need lubrication from the output parts in the transmission parts to prevent the lubricating oil from leaking. The seals used for static seals and dynamic seals (generally reciprocating motion) are called oil seals. Oil seal caps refer to the sealing caps of containers involving gasoline, engine oil, lubricating oil, etc. in machinery.
[0003] The prior art discloses an oil seal cover for preventing oil leakage of a transmission shaft with application number CN202021961968.8, comprising an upper seal cover, a sealing seat being fixedly connected to the bottom of the upper seal cover, a fixing port being passed through the top of the sealing seat, a sealing frame being fixedly connected to the bottom of the sealing seat, an oil seal position being opened on the top of the upper seal cover, and a first oil seal and a second oil seal being installed on the upper seal cover through the oil seal position. The utility model extends the depth of the oil seal position of the oil seal cover from 13 mm to 25 mm by providing an oil seal position, a first oil seal and a second oil seal, so that two oil seals can be installed in the oil seal position. When dust particles enter the transmission shaft and the sealing running-in surface, the first oil seal plays an oil sealing role and the second oil seal plays a dust prevention role, thereby reducing the frequent replacement of the oil seal of the oil seal cover and the high failure rate and avoiding the problem of oil leakage, thereby increasing the service life of the oil seal cover, and increasing the service life of the original oil seal cover from 1 month to more than 10 months.
[0004] However, the oil seal cover still has the following two defects: 1. The first oil seal and the second oil seal will age after being used for a long time, and will rub against the transmission shaft during use, thereby causing wear of the first oil seal and the second oil seal, and the oil seal of the oil seal cover is not easy to replace; 2. The fixing port of the oil seal cover is fixed in position, while the roller and the oil seal cover are generally produced in matching form, that is, the fixing port on the roller corresponds to the fixing port position of the oil seal cover, and the oil seal cover is difficult to adapt to rollers of different batches or models, affecting the versatility of the oil seal cover.
