NM50-265 Polyurethane Coupling for Industrial Mental Shaft Coupling
"NM rubber coupling spider" and "NM rubber element" are both related to NM-type rubber couplings, typically referring to the elastomer (spider rubber ring) and rubber components of NM-type rubber couplings, respectively. Here is a detailed introduction to them:
- The NM-type rubber coupling mainly consists of two cast iron half-couplings and an intermediate rubber elastomer.
- The rubber elastomer, namely "NM rubber coupling spider", is spider-like in shape, usually with multiple claw-like structures that can match the convex claws of the half-couplings, playing a role in connecting and transmitting torque.
- "NM rubber element" refers to the rubber components that make up the elastomer, which are the key parts for realizing the elastic function of the coupling. They are generally made of specially designed synthetic rubber, such as nitrile rubber (NBR).
- Good elasticity and shock absorption: It can effectively absorb and buffer the vibration and impact generated during the operation of equipment, reduce damage to equipment, extend the service life of equipment, and at the same time reduce noise and improve the comfort of the working environment.
- Oil resistance and corrosion resistance: Rubber materials such as nitrile rubber have excellent oil resistance, acid and alkali resistance, and chemical corrosion resistance. They can maintain stable performance in harsh working environments and resist erosion from oils, acids, alkalis, and other chemical solvents.
- High wear resistance: It has high wear resistance, and is not prone to wear, aging and other problems even during long-term and frequent use, thus ensuring the transmission efficiency and stability of the coupling.
- Easy installation: The structure is relatively simple, and installation and disassembly are easy, which is convenient for equipment maintenance and overhaul, and can save time and labor costs.
- Ability to compensate for shaft misalignment: It can compensate for axial, radial and angular deviations generated during equipment installation and operation, enabling the equipment to operate normally within a certain deviation range, improving the installation accuracy and operational reliability of the equipment.
- Pump equipment: Such as centrifugal pumps, gear pumps, screw pumps, etc., used to connect the pump shaft and motor shaft, transmit power while effectively buffering the vibration and impact generated during pump operation.
- Fan equipment: Including centrifugal fans, axial fans, etc., which can reduce vibration and noise during fan operation and ensure the stable operation of the fan.
- Compressors: Such as air compressors, refrigeration compressors, etc., can withstand high torque and intermittent loads during compressor operation, protecting the equipment from damage.
- Transportation equipment: In transportation equipment such as conveyors, elevators, cranes, etc., it can ensure the smooth transmission of power and adapt to different working conditions.
- Other industrial equipment: It is also widely used in various industrial equipment such as mixers, crushers, reducers, printing machines, textile machines, etc., playing a role in connection and transmission.
Common outer diameter sizes include 50mm, 67mm, 82mm, 97mm, 112mm, 128mm, 148mm, 168mm, 194mm, 214mm, etc.
