Description

Technical Field

[0001] This utility model relates to the technical field of ring rolling mill equipment, specifically to a sealing structure for a conical roller of a ring rolling mill. Background Technology

[0002] A ring rolling mill, also known as a ring mill, expanding mill, or ring rolling mill, is a forging and pressing equipment that manufactures seamless ring forgings through localized plastic deformation. It is mainly used to produce ring-shaped parts such as bearing rings, gear rings, flanges, and wheel hubs, and is widely used in machinery, automotive, aerospace, and energy industries. Its process is suitable for materials such as carbon steel, stainless steel, and titanium alloys. Through combined radial and axial rolling, it achieves wall thickness reduction and diameter expansion, featuring high material utilization, continuous distribution of metal fibers, and excellent mechanical properties.

[0003] As a key component of the ring rolling machine, the conical roller operates in a harsh environment. During the ring rolling process, impurities such as metal shavings, coolant, and dust will enter the conical roller. If the sealing effect is not good, the intrusion of impurities will lead to wear of the conical roller bearing and lubrication failure, thereby affecting the service life of the ring rolling machine. Utility Model Content

[0004] The purpose of this invention is to provide a sealing structure for the conical roller of a ring rolling mill.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a conical roller sealing structure for a ring rolling mill, comprising a conical roller;

[0029] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0030] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0031] Please see the appendix Figure 1 -Appendix Figure 2 This utility model discloses a conical roller sealing structure for a ring rolling mill, comprising a conical roller 1;

[0032] The bearing assembly 2 includes a bearing 21 and a bearing housing 22; the bearing housing 22 is disposed on the tapered roller 1; the inner ring of the bearing 21 is disposed on the tapered roller 1 and the outer ring is disposed on the bearing housing 22, so that the bearing housing 22 is rotatably connected to the tapered roller 1.

[0033] The sealing unit 3 includes a first sealing component 31 and a second sealing component 32. The first sealing component 31 and the second sealing component 32 are both disposed at one end of the bearing housing 22, forming at least two isolation areas to isolate the bearing 21.

[0034] Specifically, the bearing assembly 2 can improve the coaxiality of the tapered roller 1 during rotation, and the sealing unit 3 can effectively seal and protect the bearing 21, while also preventing the leakage of lubricating fluid.

[0035] In Embodiment 1, the first sealing assembly 31 includes;

[0036] End cap 311 is located on one side of bearing assembly 2. End cap 311 and bearing housing 22 are closely fitted with sealing gasket 312 on the side that are close to each other, which is used to prevent impurities from entering bearing 21.

[0037] The sealing ring 313 is located on the outside of the end cover 311 and below the bearing housing 22, and the contact surface is in a tight fit. It is used to assist the sealing gasket 312 in increasing the reliability of the seal.

[0038] Specifically, when the end cover 311 and the bearing housing 22 are fixedly connected by bolts, the sealing gasket 312 is compressed, thereby filling the gap between the end cover 311 and the bearing housing 22, thus preventing impurities from entering the bearing 21. At the same time, during the fixing process of the end cover 311 and the bearing housing 22, the sealing ring 313 is also compressed. With the help of the elasticity of the rubber, the gap is filled, and the connection between the end cover 311 and the bearing housing 22 is auxiliaryly sealed, enhancing the sealing reliability. The sealing ring 313 and the sealing gasket 312 are both made of oil-resistant rubber in one piece, and the sealing ring 313 is an O-ring sealing ring.

[0039] In embodiment two, the second sealing assembly 32 includes;

[0040] Bushing 321 is provided on tapered roller 1 to protect the surface of tapered roller 1;

[0041] Waterproof ring 322 is located above bushing 321 and is detachably connected to tapered roller 1. Waterproof ring 322 is adapted to the contact surface of end cap 311 to initially block impurities from entering bearing 21.

[0042] Multiple oil seals 323 are provided on the end cover 311 and are in close contact with the bushing to prevent the lubricant in the bearing 21 from leaking out, while also preventing impurities from entering the bearing 21.

[0043] Specifically, there are two oil seals 323, which are arranged in a mirror image. The bushing 321 can protect the surface of the tapered roller 1 and achieve wear resistance. The waterproof ring 322 can effectively prevent coolant and impurities from entering the bearing 21.

[0044] In embodiment three, bearing 21 also includes;

[0045] The first shoulder 211 is located on one side of the bearing 21 and below the end cover 311;

[0046] The second shoulder 212 is located on the side of the bearing 21 away from the first shoulder 211 and is located below the bearing housing 22;

[0047] The first shoulder 211 and the second shoulder 212 are used to fix and limit the bearing 21.

[0048] In embodiment four, a baffle 4 is fixed to the top of the waterproof ring 322, and a water collection groove 5 is opened at the baffle 4 on the end cap 311. The two oil seals 323 are arranged in a mirror image, and a spacer 6 is provided on the side of the two oil seals 323 that are close to each other.

[0049] Specifically, the waterproof ring 322 and the baffle 4 are made of oil-resistant rubber in one piece. The baffle 4 can effectively isolate the coolant from the edge of the waterproof ring 322, reducing the probability of coolant seeping in from the edge of the waterproof ring 322. The water collection tank 5 can collect the coolant flowing into the edge of the waterproof ring 322, preventing coolant from seeping in from the edge of the waterproof ring 322.

[0050] Working principle:

[0051] First, start the ring rolling machine. When the conical roller 1 rotates, it needs to be cooled by pouring coolant. At this time, the waterproof ring 322 needs to initially block impurities and coolant. The sealing gasket 312 and sealing ring 313 between the end cover 311 and the bearing seat 22 work together to seal and prevent impurities from entering from the gap. The contact surfaces of the two oil seals 323 and the bushing 321 are in a tight fit, which can form a seal in the bearing 21 area to block fine impurities and prevent lubricant leakage. At this point, the entire process is completed.
