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.
