Star-Type Elastic Coupling is a widely used claw-type elastic buffer coupling in the field of industrial mechanical transmission. Unlike rigid transmission components, it focuses on flexible buffering, noise reduction and vibration absorption, and serves as the core function of protective equipment.
By leveraging the advantages of multiple hardness elastic bodies as options, various material housings, and diverse installation and locking methods, it can be adapted to ordinary working conditions, light-load impacts, dusty and humid environments, and can completely replace the imported ROTEX series coupling. It is compatible with the vast majority of general machinery, engineering, metallurgical and chemical equipment, and has extremely strong versatility and adaptability.
This Star-Type Elastic Coupling adopts a European-style curved claw structure design. The overall combination is scientifically reasonable, with strong structural stability, and is suitable for long-term continuous operation.
The product is composed of two half coupling units and an intermediate star-shaped elastic buffer pad. There are no redundant or complex accessories. The disassembly, maintenance, and replacement of accessories do not require professional tools. Daily maintenance is simple and convenient.
It adopts the European standard claw structure with curved surface design of the claws. The contact area of the elastic pad's grooves is larger, effectively reducing the surface pressure of the involute tooth surface. Even in heavy-load conditions, there will be no problems such as tooth surface deformation, wear, or crushing.
It is equipped with a safety limit structure. Even if the elastic body wears out over a long period, the coupling body can still transmit power stably, and will not directly cause equipment shutdown or shaft system damage, ensuring the safety of equipment operation.
Star-Type Elastic Coupling supports multiple material and hardness combinations. It can precisely match the model according to the customer's load, speed, and working conditions, eliminating the drawback of a single specification being suitable for all working conditions.
The main body of the coupling can be made of powder alloy cast iron, ordinary cast iron, ductile iron, steel, aluminum alloy, etc., suitable for different usage requirements such as light load, medium load, heavy load, and lightweight equipment.
The intermediate elastic pad uses high-quality polyurethane material, offering four different hardness options of 80A, 92A, 98A, and 64D. Corresponding to different torque parameters, 92A is the industry standard type, meeting the needs of the vast majority of routine working conditions.
Different hardness elastomers use differentiated colors to distinguish, allowing customers to quickly identify the specifications and avoid mixed installation and model mismatch, facilitating on-site management and spare parts replacement.
The Star-Type Elastic Coupling boasts excellent environmental tolerance and operational performance, capable of adapting to complex outdoor and workshop harsh conditions. Its stability far exceeds that of ordinary simple couplings.
The applicable working temperature range is from -20℃ to 80℃. It does not crack at low temperatures or soften at high temperatures, and can be used stably in all four seasons.
It has good resistance to oil, dust, sand, and moisture. It can operate continuously in damp, dusty, and slightly oily workshop conditions without aging or failing.
By relying on the flexible buffering characteristic of polyurethane elastomer, it can effectively absorb the vibrations and impacts generated by equipment startup, shutdown, and load fluctuations, reducing equipment noise and protecting the motor and main shaft.
Supports various locking forms such as flat key connection, spline connection, single-slot locking, and conical friction locking. It is suitable for different shaft diameters and transmission installation requirements, ensuring firm fixation without slippage.
Includes extended middle type, contracted middle type, standard contracted type, flange type, etc. It can be adapted to different installation spacings and installation positions of equipment scenarios.
Parameters, dimensions, and performance can perfectly match the German ROTEX coupling. It can directly replace imported products, significantly reducing the cost of equipment component procurement.
Various conventional transmission equipment and universal power transmission devices for shaft connection and buffering transmission.
Power transmission systems for water conservancy engineering equipment and construction machinery, suitable for outdoor and heavy-load fluctuating working conditions.
Star-Type Elastic Coupling can be adapted to metallurgy, mining and chemical equipment, capable of withstanding complex working environments such as dust, oil contamination and slight corrosion.
