A lightweight composite material floating oil seal structure

Abstract

This utility model belongs to the field of lightweight technology, and particularly relates to a lightweight composite material floating oil seal structure, including an inner ring one, an inner ring two on the right side of the inner ring one, a composite layer, an outer ring one, and an outer ring two on the outer side of the inner ring one, and multiple fixed cylinders fixedly connected to the right side wall of the inner ring one, with limit rods slidably installed on the inner side walls of the multiple fixed cylinders. This utility model's device is mainly composed of a modular design, which can significantly reduce weight. Combined with multiple openings, it can further reduce the burden caused by weight. The inner ring two can be horizontally adjusted, which mainly serves to reinforce and support the outer composite layer, outer ring one, and outer ring two according to actual conditions.

The reinforcing bolts also improve the overall structural strength of the equipment.

Description

Technical Field

[0001] This utility model relates to the field of lightweight technology, and in particular to a lightweight composite material floating oil seal structure. Background Technology

[0002] Floating oil seals, as core sealing components in the transmission systems of engineering machinery (such as excavators and tunnel boring machines) and heavy vehicles, have long faced the challenges of extreme working conditions (mud, high pressure, and high wear). Traditional structures mostly use all-metal components (such as alloy steel).

[0003] However, this design of floating oil seals presents a problem: the extra mass of rotating parts in heavy equipment can lead to increased energy consumption, and this potential risk can shorten the service life of materials and may even cause material failure.

[0004] To address the above issues, we propose a lightweight composite material floating oil seal structure. Utility Model Content

[0005] The purpose of this invention is to solve the problems in the background technology by proposing a lightweight composite material floating oil seal structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a lightweight composite material floating oil seal structure, including an inner ring one, an inner ring two on the right side of the inner ring one, a composite layer, an outer ring one, and an outer ring two on the outer side of the inner ring one, a plurality of fixed cylinders fixedly connected to the right side wall of the inner ring one, a limit rod slidably provided on the inner side wall of the plurality of fixed cylinders, the limit rod slidably passing through the inner ring two, a nut threaded on the outer side of the limit rod, and a washer slidably provided on the outer side of the limit rod.

[0007] In the aforementioned lightweight composite floating oil seal structure, the composite layer is fixedly sleeved on the outer side of the inner ring one, and the inner side of the composite layer slides in contact with the outer side of the inner ring two. The composite layer is made of rubber.

[0008] In the aforementioned lightweight composite floating oil seal structure, outer ring one and outer ring two are both sleeved on the outside of the composite layer. Outer ring one and outer ring two are fixedly connected to the composite layer by multiple reinforcing bolts. The reinforcing bolts penetrate the composite layer and are fixedly connected to the outer side wall of inner ring one. Both outer ring one and outer ring two are provided with multiple openings.

[0009] In the aforementioned lightweight composite floating oil seal structure, multiple fixed cylinders are evenly arranged on the right side of the inner ring, and the gasket is located inside the nut.

[0010] In the aforementioned lightweight composite floating oil seal structure, a fixing block 1 is fixedly connected to the bottom of the outer ring 1, and a fixing block 2 is fixedly connected to the bottom of the outer ring 2. The fixing block 1 is connected to the fixing block 2 by two reinforcing bolts.

[0011] In the aforementioned lightweight composite floating oil seal structure, the outer ring one is located on the right side of the composite layer, the outer ring two is located on the left side of the composite layer, and a plurality of reinforcing bolts are evenly arranged on the outer sides of the outer ring one and the outer ring two.

[0012] Compared with existing technologies, the advantages of this lightweight composite material floating oil seal structure are: This utility model device is mainly composed of modular design, which can significantly reduce weight. With multiple openings, the burden caused by weight can be further reduced. The inner ring two can be adjusted horizontally, which can be used to reinforce and support the outer composite layer, outer ring one, and outer ring two according to the actual situation. Since the actual stress on the components is not necessarily uniform during operation, this provides a larger adjustment space. The reinforcing bolts are also used to improve the overall structural strength of the equipment. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figures 1-3A lightweight composite floating oil seal structure includes an inner ring 1, an inner ring 2 on the right side of the inner ring 1, a composite layer 7, an outer ring 8, and an outer ring 9 on the outer side of the inner ring 1. Multiple fixing cylinders 3 are fixedly connected to the right side wall of the inner ring 1. Limiting rods 4 are slidably installed on the inner side walls of the multiple fixing cylinders 3, passing through the inner ring 2. Nuts 5 are threaded onto the outer side of the limiting rods 4, and washers 6 are slidably installed on the outer side of the limiting rods 4. The composite layer 7 is fixedly fitted on the outer side of the inner ring 1, with its inner side slidingly contacting the outer side of the inner ring 2. The composite layer 7 is made of rubber. Outer rings 8 and 9 are fitted on the outer side of the composite layer 7, and are fixedly connected to the composite layer 7 by multiple reinforcing bolts 11. The reinforcing bolts 11 pass through the composite layer 7 and are fixedly connected to the outer side wall of the inner ring 1. Both outer rings 8 and 9 have multiple openings 10. The fixed cylinder 3 is evenly arranged on the right side of the inner ring 1, the washer 6 is located inside the nut 5, the outer ring 8 is located on the right side of the composite layer 7, the outer ring 9 is located on the left side of the composite layer 7, and multiple reinforcing bolts 11 are evenly arranged on the outside of the outer ring 8 and the outer ring 9. This device is mainly composed of modular components, which can significantly reduce the weight. With multiple openings 10, the burden caused by the weight can be further reduced. The inner ring 2 can be horizontally adjusted, which can be used to reinforce and support the outer composite layer 7, outer ring 8, and outer ring 9 according to the actual situation. Since the actual force on the components is not necessarily uniform during operation, this provides a larger adjustment space. The reinforcing bolts 11 are also used to improve the overall structural strength of the equipment. The high elasticity of the rubber material can compensate for end face wear, maintain sealed contact under vibration or axial movement conditions, and absorb mechanical vibration to reduce noise.

[0017] The bottom of outer ring 8 is fixedly connected to fixing block 12, and the bottom of outer ring 9 is fixedly connected to fixing block 23. Fixing block 12 is connected to fixing block 23 by two reinforcing bolts 14. Since this structure is composed of modular structure, the connection between fixing block 12 and fixing block 23 is mainly used to reinforce the stability of outer ring 8 and outer ring 9.

[0018] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.

[0019] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
