The shaft refers to a device that connects two shafts or shafts and rotating parts, rotates together in the process of transmitting motion and power, and does not disengage under normal circumstances. Sometimes it is also used as a safety device to prevent the connected parts from being subjected to excessive load, and plays the role of overload protection.
Couplings are also called couplings. A mechanical component used to
firmly connect the driving shaft and the driven shaft in different
mechanisms to rotate together and transmit motion and torque.
Sometimes it is also used to connect shafts and other parts (such
as gears, pulleys, etc.). It is often composed of two halves, which
are respectively connected by keys or tight fittings, and are
fastened at the ends of the two shafts, and then the two halves are
connected in some way. The coupling can also compensate for the
offset (including axial offset, radial offset, angular offset or
comprehensive offset) between the two shafts due to inaccurate
manufacturing and installation, deformation during operation or
thermal expansion, etc. ; and shock mitigation and vibration
absorption.
Most of the commonly used couplings have been standardized or
standardized. Generally, it is only necessary to correctly select
the type of coupling and determine the type and size of the
coupling. When necessary, the load capacity can be checked and
calculated for its vulnerable weak links; when the rotation speed
is high, the centrifugal force of the outer edge and the
deformation of the elastic element should be checked, and the
balance check should be c
arried out.
type editor broadcast
Couplings can be divided into two categories: rigid couplings and
flexible couplings.
Rigid couplings do not have buffering properties and the ability to
compensate for the relative displacement of the two axes, requiring
strict alignment of the two axes. , Easy maintenance, can ensure
high neutrality of the two shafts, large transmission torque, and
wide application. Commonly used are flange couplings, sleeve
couplings and jacket couplings.
Flexible couplings can be divided into flexible couplings with no
elastic elements and flexible couplings with elastic elements. The
former type only has the ability to compensate for the relative
displacement of the two axes, but it cannot buffer and reduce
vibration. The common ones are slippery. Block couplings, gear
couplings, universal couplings and chain couplings, etc.; the
latter type contains elastic elements, in addition to the ability
to compensate for the relative displacement of the two axes, it
also has the functions of buffering and damping. However, due to
the limitation of the strength of the elastic element, the
transmitted torque is generally not as good as the flexible
coupling without elastic element. The common elastic sleeve pin
coupling, elastic pin coupling, plum-shaped coupling, tire type
coupling Couplings, serpentine spring couplings and reed couplings,
etc.
performance requirements
According to different working conditions, the coupling needs to
have the following properties:
(1) Portability. The mobility of the coupling refers to the ability
to compensate for the relative displacement of the two rotating
components. Factors such as manufacturing and installation errors
between connected components, temperature changes during operation,
and deformation under load all place requirements on portability.
Movable performance compensates or relieves additional loads
between shafts, bearings, couplings and other components due to
relative displacement between rotating components.
(2) Buffering. For occasions where frequent load starts or working
load changes, the coupling needs to have elastic elements for
buffering and vibration damping to protect the prime mover and the
working machine from being damaged or not damaged.
(3) Safe, reliable, with sufficient strength and service life.
(4) Simple structure, convenient assembly and disassembly and
maintenance.
Selection of Coupling Type When selecting a coupling type, the following items should be considered.
