Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.
The reverse waterproof device of the oil film bearing is suitable for the roller provided with the oil film bearing, including but not limited to a supporting roller, a working roller and the like of a rolling mill. The technical scheme provided by the embodiment of the invention is described in detail below with reference to the accompanying drawings.
As shown in fig. 2, the reverse waterproof device of an oil film bearing according to an embodiment of the present invention includes: a water seal 3, a sealing cover 2 and a wear-resistant part; the water seal 3 is fixed on the end face of the roller 4 through a threaded connecting piece 5 and rotates along with the roller 4, the sealing cover 2 is fastened on the bearing seat 1 of the oil film bearing through a bolt, the wear-resistant part is a wear-resistant surface 6 arranged on the end face of the sealing cover 2, and a water seal lip 31 of the water seal 3 keeps contact with the wear-resistant surface 6.
As shown in fig. 3, the reverse waterproof device of an oil film bearing according to another embodiment of the present invention includes: a water seal 3, a sealing cover 2 and a wear-resistant part; the water seal 3 is fixed on the end face of the roller 4 through a threaded connecting piece 5 and rotates along with the roller 4, the sealing cover 2 is fastened on the bearing seat 1 of the oil film bearing through a bolt, the wear-resistant part is a wear-resistant ring 7 arranged on the end face of the sealing cover 2, and a water seal lip 31 of the water seal 3 is in contact with the end face of the wear-resistant ring 7.
In practical use of the reverse waterproof device of the oil film bearing of the present invention, the above-described embodiment of the wear-resistant surface 6 or the embodiment of the wear-resistant ring 7 may be selected according to the size of the spatial position of the seal cover 2, and when the spatial position of the seal cover 2 is sufficient, the wear-resistant surface 6 is provided on the end surface of the seal cover 2, and when the spatial position of the seal cover 2 is insufficient, the wear-resistant ring 7 is provided on the end surface of the seal cover 2. So set up, avoid because of sealed lid 2 go up the narrow and small limitation that is difficult for setting up wear-resisting face 6 in spatial position, thereby avoided simultaneously because of sealed lid 2 go up the too big thickness that needs wear-resisting ring 7 and cause wear-resisting ring 7 manufacturing cost to increase of spatial position, make the device on the whole simpler, reasonable and the cost is lower from this.
The working principle of the reverse waterproof device of the oil film bearing is as follows: when the rolling mill works, the roller 4 rotates, the water seal 3 fixed on the end face of the roller 4 through the threaded connecting piece 5 rotates along with the roller 4, and during the rotation of the water seal 3, the water seal lip 31 of the water seal 3 is always in contact with the wear-resistant surface 6 on the sealing cover 2 or the end face of the wear-resistant ring 7, so that the sealing and waterproof effects of the oil film bearing are effectively improved, the possibility that impurities such as cooling water, iron oxide scales and the like fall into the oil film bearing during rolling is prevented, and the normal use of the oil film bearing is ensured. Meanwhile, as the water seal 3 is fixed on the end face of the roller 4, the water seal lip 31 is in contact with the wear-resistant surface 6 or the wear-resistant ring 7 on the sealing cover 2 and is not in contact with the roller end face of the roller 4, so that the abrasion of the roller end face is not caused, and the roller 4 does not need to be repaired.
Further, in the reverse waterproof device of the oil film bearing of the present invention, the wear-resistant surface 6 is formed by spraying ceramic or nitriding on the end surface of the seal cover 2, and the formed wear-resistant surface has high hardness and small friction, thereby effectively reducing the abrasion of the water seal lip 31 itself and further improving the service life of the water seal 3.
Furthermore, in the reverse waterproof device of the oil film bearing of the invention, the sealing cover 2 is provided with the sealing cover convex eaves 21, so that the impact of cooling water on the water seal lip 31 can be effectively reduced, and the service life of the device is prolonged.
Furthermore, in the reverse waterproof device of the oil film bearing, the wear-resistant ring 7 is provided with the wear-resistant ring convex eaves 71, so that the impact of cooling water on the water seal lip 31 can be effectively reduced, and the service life of the device is prolonged.
Further, in the reverse waterproof device of the oil film bearing of the present invention, the sealing manner between the seal cover 2 and the wear ring 7 is static seal.
Further, in the reverse waterproof device of the oil film bearing of the present invention, the water seal lip 31 of the water seal 3 is one or more. So set up, can further improve oil film bearing's sealed water-proof effects, impurity such as cooling water and iron scale falls into oil film bearing when effectively preventing to roll, ensures oil film bearing normal use.
In summary, the reverse waterproof device for the oil film bearing of the present invention has at least the following beneficial effects:
(1) the water seal is fixed on the end face of the roller, when the roller rotates along with the roller, a water seal lip of the water seal is always in contact with a wear-resistant surface or a wear-resistant ring on the sealing cover, the sealing and waterproof effects of the oil film bearing are effectively improved, the possibility that cooling water, iron oxide scales and other impurities fall into the oil film bearing during rolling is prevented, and the normal use of the oil film bearing is ensured.
(2) The water seal is fixed on the end face of the roller, and the water seal lip is not in contact with the roller end face of the roller, so that the abrasion of the roller end face is avoided, the roller does not need to be repaired, and the use and maintenance cost of the roller is effectively reduced.
(3) After the wear-resistant surface or the wear-resistant ring on the sealing cover is worn, the replacement or maintenance cost is low, and the operation is simple and convenient.
