Our Advantages
About Us
FEATURES AT A GLANCE
Can operate normally in corrosive environments without the need for lubrication, which can prevent lubricating oil from polluting the environment.
The connection gap is small, especially suitable for harsh working environments, and the working temperature adaptation range is wider, up to -20~+250 ℃.
Small moment of inertia, suitable for a larger range of speed and torque.
Stable operation, minimum vibration, and most no noise.
All structural components have undergone heat treatment and algorithm optimization.
All contact surfaces are high precision ground.
The product components comply with relevant standards.
Dongde
JM series
diaphragm coupling
It is an all metal connected circular coupling that not only has certain angular and radial compensation capabilities, but also has the characteristics of high torque and high energy efficiency.
Moreover, due to its coupling characteristics, it also has a smaller moment of inertia, making it particularly suitable for high torque connections at medium to high speeds.
In addition, due to the physical properties of the material, this coupling is more suitable for environments with dust or corrosive gases, and the temperature range for stable operation can be wider.
By the way, this coupling does not have rotational clearance yet, and has a little flexibility in starting and stopping, and the working noise is also smaller.
