Description

Technical Field

[0001] The utility model belongs to the technical field of seals, and particularly relates to a bearing seal ring structure. Background Technique

[0002] Bearing seals are components used to seal the lubricant inside the bearing and prevent external contaminants from entering the bearing. Their main function is to keep the grease or lubricating oil inside the bearing while preventing the entry of dust, dirt, and other contaminants, thereby extending the service life of the bearing and improving its operating efficiency. Common materials for seals include rubber, metal, and their composite materials. Different application requirements will select different materials and structures. The design of seals can be divided into various types, such as single-lip seals, double-lip seals, labyrinth seals, etc.

[0003] Currently, when sealing the main shaft, most bearing seals use Y-shaped seals. The lip of the seal fits with the main shaft. However, under long-term high-temperature and high-load conditions, the fit between the lip of the seal and the main shaft will decrease, resulting in a significant reduction in the sealing effect and accelerating the aging and damage of the seal.

[0004] Therefore, we provide a bearing seal ring structure to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a bearing seal ring structure. Through the setting of the reinforcement components, the problem that the fit between the seal ring and the main shaft of the existing bearing seal ring decreases under long-term high-temperature and high-load conditions is solved.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model is a bearing seal ring structure, including a rubber ring body. A rubber lip is fixedly connected to the bottom of the rubber ring body, and a through groove is formed on the surface of the rubber ring body.

[0008] A reinforcement component is arranged on the surface of the rubber ring body. The reinforcement component includes a reinforcing lip, which is fixedly connected inside the through groove, and a reinforcing ring is sleeved on the surface of the through groove.

[0009] The utility model is further arranged such that the top and bottom of the reinforcing ring are respectively in contact with the reinforcing lip and the inner wall of the through groove, and a first metal wire is fixedly connected inside the reinforcing ring.

[0010] The utility model is further arranged such that a buffer groove is formed inside the rubber ring body, and a support ring is arranged inside the buffer groove.

[0011] The present utility model is further configured such that a second metal wire is installed inside the support ring, and the second metal wire is made of stainless steel material.

[0012] The present utility model is further configured such that the bottom of the reinforcing lip contacts the rubber lip, and the number of support rings is three.

[0013] The present utility model is further configured such that the cross-sectional width of the rubber ring body is 16 MM, and the cross-sectional height of the rubber ring body is 14 MM.

[0014] The present utility model is further configured such that the diameter of the reinforcing ring is 4 MM, and the diameter of the support ring is 2 MM.

[0015] The present utility model has the following beneficial effects:

[0016] Through the arrangement of the reinforcing components, when the rubber ring body is installed inside the bearing, the rubber lip can be attached to the main shaft to achieve the sealing effect. At the same time, the reinforcing ring is installed inside the through groove, and the reinforcing lip can be squeezed by the reinforcing ring to achieve the attachment of the reinforcing lip and the rubber lip. During long-term high-load operation, the attachment position of the rubber lip will not change. At the same time, when the rubber lip is worn, the main shaft can be tightly pressed by the reinforcing lip to reduce the situation of seal leakage.

[0017] Of course, it is not necessary for any product implementing the present utility model to achieve all the above advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Specifically: The connection outer angle between the rubber lip 2 and the rubber ring body 1 is 100°. By tilting the rubber lip 2 downward, when the rubber ring body 1 is installed into the bearing, the rubber lip 2 can be attached to the main shaft. The bottom of the reinforcing lip 4 is in contact with the rubber lip 2, which can achieve the effect of tightening. The first metal wire 6 is installed inside the reinforcing ring 5, which can enhance the structural stability and provide additional sealing force in the seal ring. Specific Embodiment 2
