Description

TECHNICAL FIELD

[0001] The utility model relates to rubber seal ring technical field especially relates to a low friction can eliminate oil cylinder dithering abnormal sound's rubber seal ring. BACKGROUND

[0002] Rubber seal ring plays an indispensable role in various mechanical systems, and is a key part to ensure normal operation of equipment. With excellent sealing performance, it can effectively prevent leakage of liquid, gas and other media, and is widely used in many fields such as automobiles, hydraulic equipment, industrial pipelines and so on. High-quality rubber seal ring has good elasticity, wear resistance and corrosion resistance, can adapt to complex working environment, can stably play a role no matter facing high temperature, high pressure or chemical corrosion, and can ensure the sealing and reliability of the system, providing solid protection for efficient and safe operation of industrial production.

[0003] Traditional rubber seal ring usually has a simple ring structure, and the material is ordinary rubber without special additives and improved formula. The overall structure is single, mainly relying on a single sealing lip to realize sealing, and the lip shape is conventional without special design to optimize the contact. When cooperating with the sealing surface, the contact mode is rough, which is difficult to accurately fit, and there is no additional buffer or lubrication structure, relying only on the elasticity of the rubber itself for sealing, which has limited sealing performance under complex working conditions.

[0004] The contact area of the sealing surface of the traditional rubber seal ring is large and the pressure distribution is uneven, which increases the friction. At the same time, the single ring structure lacks buffering and self-adapting ability, and cannot effectively cope with the pressure fluctuation in the oil cylinder, the impact of piston movement and other situations, so that the oil cylinder is prone to dithering. Moreover, due to the poor sealing, hydraulic oil leakage will also occur, further aggravating the wear of the parts and causing abnormal sound. This not only reduces the equipment operation efficiency and increases the energy consumption, but also accelerates the equipment aging and shortens the service life. In severe cases, it may even cause equipment failure, affect production continuity and cause economic losses. UTILITY MODEL CONTENTS

[0008] Further, the outer ring is internally provided with an outer sealing lip.

[0009] Further, the inner ring is internally provided with an inner sealing lip.

[0016] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0017] REFERENCE Figs. 1-2 In one embodiment, the utility model provides a low-friction rubber sealing ring capable of eliminating oil cylinder shaking abnormal sound, which comprises a rubber ring body 1, characterized in that: the outer wall of the rubber ring body 1 is fixedly connected with an outer ring 3, the side wall of the rubber ring body 1 is fixedly connected with an inner ring 5, the inside of the rubber ring body 1 is provided with a plurality of micro convex sealing sliding sections 2, the micro convex sealing sliding sections 2 are in a ring array inside the rubber ring body 1, the inside of the outer ring 3 is provided with an outer sealing lip 4, and the inside of the inner ring 5 is provided with an inner sealing lip 6.

[0018] Specifically, in terms of low friction, the rubber ring body 1 is evenly distributed with multiple micro convex sealing sliding segments 2 in a ring shape. When in contact with the oil cylinder or piston, due to the micro convex shape, the actual contact area is reduced compared to flat contact. When the piston moves, the micro convex structure produces a ball rolling effect, further reducing friction. The gap between the micro convex sealing sliding segments 2 can store and guide lubricating oil, making it evenly distributed to form a continuous lubricating film, reducing the coefficient of friction and allowing the piston to move more smoothly in the oil cylinder. The outer ring 3 and the inner ring 5 tightly connect the rubber ring body 1, and the outer sealing lip 4 and the inner sealing lip 6 are elastic. During operation, they can adaptively adjust according to the oil cylinder pressure and piston movement state, making the contact uniform and maintaining the appropriate pressure to avoid excessive friction due to excessive pressure and ensure good sealing performance. In terms of eliminating oil cylinder shaking and abnormal noise, the outer sealing lip 4 and the inner sealing lip 6 have a buffering function while sealing. The impact force and vibration generated by the piston movement can be absorbed by the elastic deformation of the lip. For example, when the piston is started quickly, the elastic deformation of the lip converts the impact force, reducing the shaking. Because the lip is tightly attached to the oil cylinder wall and the piston, it can isolate the vibration. The elasticity and damping characteristics of the rubber ring body 1 convert the vibration energy into heat energy and hinder the transmission of vibration. The rubber ring body 1, outer ring 3, inner ring 5, and micro convex sealing sliding segments 2 work together. The rubber ring body 1 provides support to ensure the correct position and shape of each part. The micro convex sealing sliding segments 2 reduce friction and maintain smooth piston movement. The sealing lips of the outer ring 3 and the inner ring 5 buffer and seal, improving the stability of the oil cylinder. In the face of pressure fluctuations, the entire structure adjusts in coordination to maintain sealing performance and effectively eliminate oil cylinder shaking and abnormal noise problems.

[0019] Working principle: in terms of low friction, the plurality of micro convex sealing sliding sections 2 distributed in the annular rubber ring body 1, when in contact with the oil cylinder or piston, reduce the actual contact area, when the piston moves, the micro convex structure produces a ball rolling effect, further reducing friction, the gap can also store and guide lubricating oil, forming a lubricating film, reducing the friction coefficient. In addition, the outer ring 3 and the inner ring 5 tightly connect the rubber ring body 1, the outer sealing lip 4 and the inner sealing lip 6 are elastic, which can adaptively adjust according to the pressure and movement state, so that the contact is uniform, the appropriate pressure is maintained, and excessive friction is avoided due to excessive pressure. In terms of eliminating the abnormal noise of the oil cylinder, the outer sealing lip 4 and the inner sealing lip 6 have a buffering function when focusing on sealing, and the impact force and vibration generated by the movement of the piston can be absorbed by the elastic deformation of the lip, such as when starting quickly, the deformation of the lip converts the impact force, reducing the shaking. Since the lip is tightly attached to the oil cylinder wall and the piston, it can isolate vibration, and the elastic and damping properties of the rubber ring body 1 convert vibration energy into heat energy dissipation, hindering vibration propagation. The rubber ring body 1, the outer ring 3, the inner ring 5 and the micro convex sealing sliding section 2 work together, the rubber ring body 1 provides support to ensure the correct position and shape of each part, the micro convex sealing sliding section 2 reduces friction and maintains smooth piston movement, the sealing lip of the outer ring 3 and the inner ring 5 buffers and seals, improving the stability of the oil cylinder, and the entire structure cooperates to adjust to maintain sealing performance, effectively eliminating the abnormal noise of the oil cylinder.

[0020] Finally, it should be pointed out that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the present application has been described in detail with reference to the foregoing embodiments, for those skilled in the art, it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
