Description

Technical Field

[0001] The utility model belongs to the technical field of oil seals, and in particular relates to a composite floating oil seal structure. Background Art

[0002] A floating oil seal is a sealing device used in mechanical equipment. It is usually used to prevent lubricating oil or other lubricating media from leaking from the inside of the equipment to the external environment. A floating oil seal is usually composed of metal parts and elastic sealing elements to prevent lubricating oil from flowing out and prevent external dust and impurities from entering the interior of the mechanical equipment.

[0003] At present, in order to facilitate installation and fixation on equipment, traditional floating oil seals often have threaded holes for installation on the floating seal seats. However, when the threaded holes are opened, they are usually opened directly on the floating seal seats. Since the threaded holes are directly opened on the floating seal seats of traditional floating oil seals, if the threads are twisted too hard or improperly operated during installation, it is easy to cause surface damage to the threaded holes, such as bruises, collapse or poor cutting. These damages will seriously affect the quality of the threaded holes and make the floating seal seats unusable. In the face of damaged floating seal seats, the traditional practice usually requires replacing the entire floating seal seat to repair the problem of the threaded holes. Especially for large-volume and high-cost floating oil seals used on large equipment, this practice will lead to high replacement costs.

[0004] To this end, we propose a composite floating oil seal structure to solve the above problems. Utility Model Content

The mounting seat 6 is of Z-shaped design, so that the mounting seat 6 is flush with the end surface of the corresponding floating seal seat 1 after being inserted into the socket 5. A threaded hole 7 is provided on the mounting seat 6. A plurality of sliding cavities 8 are provided at the position of the floating seal seat 1 near the socket 5, and an electromagnetic block 9 is fixedly arranged in the sliding cavity 8. The model of the electromagnetic block 9 is KK-P65. The electromagnetic block 9 is fixedly connected to a permanent magnet block 11 through a reset spring 10, and the permanent magnet block 11 is slidably connected to the corresponding sliding cavity 8.

[0028] The operating principle of the utility model is now described as follows:

[0029] When the threaded hole 7 on the floating oil seal is damaged and needs to be replaced, the corresponding electromagnetic blocks 9 are controlled by the switch 20 to be energized and magnetized, so that the electromagnetic block 9 attracts the corresponding permanent magnet block 11, so that the permanent magnet block 11 drives the fixing rod 12 to move downward, and then drives the clamping plate 13 to move downward, so that the clamping plate 13 is separated from the corresponding mounting seat 6, and the mounting seat 6 is unlocked. Subsequently, the mounting seat 6 corresponding to the damaged threaded hole 7 is pulled out, and then the new mounting seat 6 accessory is inserted into the corresponding socket 5. Subsequently, the corresponding electromagnetic blocks 9 are controlled by the switch 20 to be powered off and demagnetized, so that the electromagnetic block 9 no longer attracts the permanent magnet block 11, so that the reset spring 10 releases energy, so that the fixing rod 12 drives the corresponding clamping plate 13 to extend to clamp and fix the new mounting seat 6, and lock the mounting seat 6. Then, the staff can use the new threaded hole 7 for installation.
