KAYSEVEN
Compact, simple structure, with easy to absorb eccentricity and centering. Widely used in robots, resin molding materials, conveying equipment, printing machines, machine tools, and pumps etc.
[Features]
· Compact and simple structure.
· Like the MD series, it consists of three parts, the hub parts and an intermediate torque transmission part.
· Oldham type coupling absorbs eccentric misalignment.
· Dial gauge is not necessary for centering work at installation.
· Visual observation is sufficient.
· The intermediate torque transmission part is made of resin, and so does not require lubricant.
· No reactive force due to misalignment, contributing to energy conservation, with assembly and installation easy.
· Simple structure, and even in the event of damage to the intermediate transmission part, power transmission is possible.
· Thermally and electrically insulated by the intermediate transmission part.
· Friction joint employed for fastening to shaft.Type Shaft Bore Dia. (machined) D1(Ø) Shaft Bore Dia. (machined) D2(Ø) Outer Dia.

FAQ Flexible Shaft Couplings
- Question: What are the different types of flexible Shaft Couplings?
- Answer: There are several types of flexible Shaft Couplings, including beam, bellows, jaw, Oldham, disc, diaphragm, and gear couplings. Each type has unique features and benefits that make them suitable for different applications and environments. Flexible Shaft Couplings are used to connect two shafts and allow for misalignment while transmitting torque between them.
- Question: What factors should be considered when selecting a flexible Shaft Couplings?
- Answer: The factor for selecting a flexible coupling, there are several factors that should be considered, including the required torque capacity, misalignment capability, operating speed, and environmental factors such as temperature and humidity. Other considerations include the required degree of axial and radial stiffness, the space available for the coupling, and the type of equipment being connected. It is also important to consider the potential for wear and tear, maintenance requirements, and the cost of the coupling.
- Question: How is a flexible Shaft Couplings installed and maintained?
- Answer: Shaft Couplings are installed by aligning the shafts and tightening the screws or bolts. Maintenance involves regular inspections for signs of wear, damage, or misalignment. Lubrication is important to prevent excessive wear and reduce friction. Cleaning and tightening of bolts and screws are also necessary to ensure proper operation.
- Question: What is the difference between a flexible coupling and a rigid coupling?
- Answer: A flexible coupling allows for some misalignment between two connected shafts while transmitting torque, while a rigid coupling does not allow for any misalignment. Flexible Shaft Couplings are designed to absorb shock and vibration, which can help reduce wear and tear on connected equipment. Rigid couplings, on the other hand, are used in applications where precise alignment between shafts is critical, such as in high-speed rotating equipment or precision machinery.
