Description

Technical Field

[0001] This utility model relates to the field of coupling technology, specifically a coupling with an optimized sealing structure. Background Technology

[0002] In industrial transmission systems, couplings, as key components connecting the shafts of different equipment and transmitting torque, are widely used in metallurgy, mining, chemical and other fields. These applications are often accompanied by complex working conditions such as high dust concentration, coolant splashing, high humidity or frequent vibration, which places stringent requirements on the sealing performance and structural stability of couplings.

[0003] Currently, most couplings on the market employ a single sealing ring or a simple gland design for their sealing structure, which has significant drawbacks. Firstly, the sealing protection is limited, allowing external contaminants such as dust, metal shavings, and coolant to easily penetrate critical transmission components like gears and bearings. This accelerates wear and corrosion, shortening the coupling's lifespan, frequently causing equipment downtime, and increasing production and maintenance costs. Secondly, the insufficient sealing of existing structures allows lubricants (such as grease and oil) inside the coupling to fail due to splashing, evaporation, or contamination, further exacerbating component wear. Furthermore, these existing structures are incompatible with the sway function of some couplings, making them prone to seal failure during operation. In addition, some couplings lack effective buffering and observation structures, making them unable to withstand minor vibrations and impacts during operation, and hindering real-time monitoring of internal lubrication and sealing conditions, thus complicating equipment maintenance.

[0004] Based on this, a coupling with an optimized sealing structure is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0005] The purpose of this invention is to provide a coupling with an optimized sealing structure to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A coupling with an optimized sealing structure includes an inner gear ring at the roller end, an outer gear sleeve at the roller end, an inner gear ring at the gear end, and an outer gear sleeve at the gear end. The inner gear ring at the roller end and the outer gear sleeve at the roller end are connected by a gear pair. A pressure cap is bolted between the inner gear ring at the roller end and the outer gear sleeve at the roller end. A sealing cover is provided on the outside of the outer gear sleeve at the roller end and the inner gear ring at the roller end. One end of the sealing cover is connected to the outer gear sleeve at the roller end through a clamp, and the other end is connected to the inner gear ring at the roller end through a clamp. The sealing cover covers the outside of the pressure cap.

[0007] Based on the above technical solutions, this utility model also provides the following optional technical solutions: In one alternative: the inner gear ring at the roller end is mounted with an intermediate shaft via a retainer, the outer gear sleeve at the gear end is bolted with a pressure cap two, the pressure cap two is welded with a protective cover, and the protective cover is slidably connected to the intermediate shaft.

[0008] In one alternative: the protective cover has ventilation and observation holes on its periphery.

[0009] In one alternative: a sealing ring is provided between the protective cover and the intermediate shaft.

[0010] In one alternative: the outer toothed bushing at the roller end is bolted with a pressure cap three, and a sealing ring two is embedded between the pressure cap three and the outer toothed bushing at the roller end.

[0011] In one alternative: the inner gear ring at the tooth end is bolted to a pressure cap four, and a wear-resistant copper ring is installed between the pressure cap four and the outer gear sleeve at the tooth end.

[0012] In one alternative embodiment, a radial sealing ring and an axial sealing ring are provided between the wear-resistant copper ring and the toothed external gear bushing.

[0013] In one alternative: an axial sealing ring is provided between the pressure cap and the outer toothed bushing of the roller end.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention achieves all-around sealing protection through a multi-layered sealing structure design. Rubber sealing covers on the outer sides of the roller end outer toothed bushing and the roller end inner toothed ring, fixed with clamps, directly prevent external dust, iron filings, coolant, and other contaminants from entering the roller end assembly. The tooth end, through a combination of pressure cap four, a wear-resistant copper ring, and radial and axial sealing rings, effectively prevents contaminants from intruding into the tooth end transmission parts. Simultaneously, the axial sealing ring between pressure cap one and the roller end outer toothed bushing, and the sealing ring two between pressure cap three and the roller end outer toothed bushing, further enhance the sealing effect, significantly reducing the risk of component wear and corrosion caused by contaminants.

[0015] This invention effectively retains lubricant inside the coupling through a multi-seal structure, reducing lubricant failure caused by splashing, evaporation, or contamination. This ensures long-term effective lubrication of critical components such as gears and bearings, and reduces component wear rates. This not only extends the lubricant replacement cycle and reduces the frequency of lubrication replenishment during maintenance, but also lowers the probability of equipment failure due to insufficient lubrication, significantly saving maintenance costs for enterprises.

[0016] The wear-resistant copper ring design of this utility model achieves effective sealing while adapting to the tooth end swing angle function of the coupling, without interfering with the swing angle movement, thus ensuring the smoothness of the transmission process.

[0017] The rubber sealing cover of this utility model has a certain degree of elasticity, which can play a buffering role when the roller end assembly generates slight vibration during operation, reducing the impact of vibration on the sealing part and connection structure, and indirectly improving the structural stability and operational reliability of the entire coupling.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In one embodiment, such as Figures 1-5 As shown, a coupling with an optimized sealing structure includes an inner gear ring 1 at the roller end, an outer gear sleeve 2 at the roller end, an inner gear ring 8 at the gear end, and an outer gear sleeve 9 at the gear end. The inner gear ring 1 and the outer gear sleeve 2 at the roller end are connected by a gear pair, and the inner gear ring 8 and the outer gear sleeve 9 at the gear end are also connected by a gear pair. A pressure cap 3 is bolted between the inner gear ring 1 and the outer gear sleeve 2 at the roller end. A sealing cover 11 is provided on the outside of the outer gear sleeve 2 and the inner gear ring 1 at the roller end. One end of the sealing cover 11 is connected to the outer gear sleeve 2 at the roller end through a clamp 12, and the other end is connected to the inner gear ring 1 at the roller end through a clamp 23. The sealing cover 11 covers the outside of the pressure cap 3.

[0026] By adding a rubber sealing cover 11, contaminants can be effectively blocked, the deterioration of internal lubricants such as grease and lubricating oil due to external contamination can be reduced, and the loss of lubricant due to splashing, evaporation and other reasons can be reduced, ensuring the durability of lubrication effect and reducing the frequency of lubrication replenishment during maintenance.

[0027] The sealing cover 11 is made of rubber. Rubber has a certain degree of elasticity and can buffer the slight vibration generated when the roller end assembly is running, reducing the impact of vibration on the sealing part or connection structure, and indirectly protecting the stability of the assembly.

[0028] In environments with high dust levels, high humidity, or liquid splashes, the rubber sealing cover 11 provides additional protection for the roller end assembly, making the assembly more adaptable to harsh environments and reducing downtime for maintenance due to environmental factors.

[0029] In one embodiment, the inner toothed ring 1 at the roller end is mounted with an intermediate shaft 6 via a retainer 5, and the outer toothed bushing 9 at the tooth end is mounted with a pressure cap 4 via bolts. The pressure cap 4 is welded with a protective cover 7, and the protective cover 7 is slidably connected to the intermediate shaft 6.

[0030] The protective cover 7 can protect the intermediate shaft 6 from external dust.

[0031] In one embodiment, ventilation and observation holes 14 are provided on the circumference of the protective cover.

[0032] The ventilation and observation holes 14 on the 7th side of the protective cover allow staff to observe the lubrication and sealing status inside the coupling in real time, identify potential problems in time, and reduce unnecessary disassembly and maintenance; at the same time, the ventilation design can also balance the internal air pressure and avoid the sealing effect being affected by air pressure difference.

[0033] In one embodiment, a sealing ring 10 is provided between the protective cover 7 and the intermediate shaft 6 to improve the sealing performance of the coupling.

[0034] In one embodiment, a pressure cap 16 is bolted to the outer gear sleeve 2 at the roller end, and a sealing ring 15 is embedded between the pressure cap 16 and the outer gear sleeve 2 at the roller end. This further improves the sealing performance of the coupling.

[0035] In one embodiment, the inner tooth ring 8 at the tooth end is bolted to a pressure cap 18, and a wear-resistant copper ring 17 is installed between the pressure cap 18 and the outer tooth bushing 9 at the tooth end.

[0036] By adding a pressure cap 18 and a wear-resistant copper ring 17, and optimizing the sealing layout, it is possible to effectively prevent contaminants such as dust and coolant from entering the tooth ends; retain internal lubricant to reduce tooth end wear; adapt to the tooth end swing angle function without interfering with the swing angle movement; improve the wear resistance and service life of the sealing structure, and ensure the long-term stable operation of the equipment.

[0037] In one embodiment, a radial sealing ring and an axial sealing ring are provided between the wear-resistant copper ring 17 and the toothed external gear sleeve 9.

[0038] In one embodiment, an axial sealing ring is provided between the gland 3 and the outer toothed bushing 2 at the roller end.

[0040] Protects internal lubrication: Reduces the deterioration of internal lubricants such as grease and oil due to external contamination, while also reducing lubricant loss due to splashing, evaporation, etc., ensuring the durability of lubrication effect and reducing the frequency of lubrication replenishment during maintenance.

[0041] Buffering and shock absorption: The sealing cover 11 is made of rubber. Rubber has a certain elasticity and can buffer when the roller end assembly generates slight vibration during operation, reducing the impact of vibration on the sealing part or connection structure, and indirectly protecting the stability of the assembly.

[0042] Adaptable to complex environments: In working conditions with a lot of dust, high humidity or liquid splashes, the rubber sealing cover 11 can provide extra protection for the roller end assembly, making the assembly more adaptable to harsh environments and reducing downtime maintenance caused by environmental factors.

[0043] By adding a pressure cap 18 and a wear-resistant copper ring 17, and optimizing the sealing layout, it is possible to effectively prevent contaminants such as dust and coolant from entering the tooth ends; retain internal lubricant to reduce tooth end wear; adapt to the tooth end swing angle function without interfering with the swing angle movement; improve the wear resistance and service life of the sealing structure, and ensure the long-term stable operation of the equipment.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application.
