Description

Technical Field

[0001] This utility model belongs to the field of sealing ring technology, and in particular relates to a wear-resistant rubber sealing ring. Background Technology

[0002] Rubber seals, as key components in the sealing field, are widely used in various industries. In the early days, traditional rubber seals had limitations in temperature resistance and chemical corrosion resistance. Under harsh conditions such as high temperature and strong acids and alkalis, they were prone to aging and deformation, leading to sealing failure, leakage, and other problems, affecting the normal operation of equipment and even causing safety hazards. As modern industry develops towards high precision and high reliability, higher requirements are placed on the performance of rubber seals. Developing new rubber seals with excellent weather resistance, wear resistance, and sealing stability to adapt to complex working conditions has become a key issue that the industry urgently needs to address.

[0003] However, existing rubber seals are prone to wear during use due to friction. Over time, the sealing performance of the rubber seals will decrease, requiring frequent replacement. This not only consumes a lot of resources for replacement but also disrupts production and reduces work efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a wear-resistant rubber sealing ring. By setting a compensation mechanism, it solves the problem that the friction part of the existing rubber sealing ring is easily worn during use, and the sealing performance of the rubber ring will decrease over time, requiring frequent replacement of the rubber ring. This not only consumes a lot of resources for rubber ring replacement, but also interrupts production and reduces work efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a wear-resistant rubber sealing ring, including a main body, on which a compensation mechanism and a sealing mechanism are provided;

[0007] The compensation mechanism includes a groove formed in the inner wall of the main body, and a soft rubber sheet is fixedly connected to the inner wall of the groove. The sealing mechanism includes a contact layer fixedly connected to the outer wall of the main body. The main body is made of rubber, the soft rubber sheet is made of high-elastic rubber, and the contact layer is made of hard rubber.

[0008] Furthermore, the inner wall of the soft rubber sheet is provided with a second groove, and a friction block is fixedly connected to the inner wall of the second groove. A connecting ring is fixedly connected to the outer wall of the soft rubber sheet. A third groove is provided inside the connecting ring, and a spring ring is fitted inside the inner wall of the third groove. Several limiting blocks are fixedly connected to the left and right sides of the connecting ring. The outer walls of the several limiting blocks are in contact with the first groove. The friction block is made of wear-resistant rubber, the connecting ring is made of high-elastic rubber, and the spring ring is made of elastic metal.

[0009] Furthermore, protective layers are fixedly connected to the left and right sides of the main body. The sides of the two protective layers that are close to each other are fixedly connected to the contact layer. The outer wall of the contact layer is provided with a plurality of grooves four. The inner wall of each of the plurality of grooves four is fixedly connected with a sealing ring. The sealing ring is provided with a groove five. The inner wall of each of the plurality of grooves five is fixedly connected with a steel ring. The protective layer is made of hard rubber, the sealing ring is made of rubber, and the steel ring is made of hard metal.

[0010] This utility model has the following beneficial effects:

[0011] 1. By setting up a compensation mechanism, when the equipment is running continuously and the friction block is worn, the friction block will retract inward. At this time, under the action of the soft rubber sheet and the connecting ring, the elastic force stored in the spring ring will push the friction block to fit tightly against the output shaft of the equipment. Under the action of the limit block, the friction block will be prevented from shifting, so that the worn part of the rubber ring can be compensated, allowing the rubber ring to maintain its sealing performance continuously without frequent replacement. This not only saves resources but also ensures the stability of the production process.

[0012] 2. By setting a sealing mechanism, the entire device can be embedded into the corresponding equipment, allowing the contact layer to fit against the inner wall of the equipment. At this time, supported by the steel ring, the outer wall of the device will be sealed by the sealing ring. Under the protection of the protective layer, the entire device will be protected from direct damage. Then, the corresponding output shaft can be inserted into the device. At this time, the entire compensation mechanism will be subjected to an outward force, which will cause the entire compensation mechanism to have an inward contraction force. This ensures that the rubber ring can be installed on the required machinery, thus guaranteeing the sealing performance of the contact area and further ensuring the sealing performance of the rubber ring.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] Please see Figure 1-5As shown, this utility model is a wear-resistant rubber sealing ring, including a main body 1.

The main body 1 is made of rubber, the soft rubber sheet 202 and the connecting ring 205 are made of high-elastic rubber, the friction block 204 is made of wear-resistant rubber, and the spring ring 207 is made of elastic metal. By setting the compensation mechanism 2, the worn parts in the rubber ring can be compensated, so that the rubber ring can maintain its sealing performance continuously without frequent replacement. This not only saves resources, but also ensures the stability of the production process.

[0024] The sealing mechanism 3 includes a contact layer 301 fixedly connected to the outer wall of the main body 1. Protective layers 302 are fixedly connected to the left and right sides of the main body 1.

[0025] A specific application of this embodiment is as follows: In use, the entire device can be embedded into the corresponding equipment, so that the contact layer 301 fits against the inner wall of the equipment.
