Coupling Force Reliable


Couplings are often used to couple two shafts and transmit motion and torque therebetween; have the ability to absorb vibration and to moderate shock; can be used as a safety device to prevent the connector from being subjected to excessive loads and overload protection Function; coupling with the coupling shaft only when the machine stops running, Voss Push in Couplings after the demolition of the two shafts can be separated.

Classification requirements

Fixed coupling: the required connection of the two axis center line strictly aligned;

Movable coupling: allows two axes to have a certain installation error.

Elastic Couplings: One of the elastic elements of different materials, in a certain range to compensate for the displacement between the two axes, Voss Push in Couplings as well as the role of buffer damping.

Displacement compensation

The two axes of the coupling are often affected by a certain degree of relative displacement and deflection due to manufacturing and installation errors, post - load deformation, bearing wear, Voss Push in Couplings unbalance of rotating parts and temperature changes.

Coupling from the structure to take a variety of measures to make the coupling with a variety of offset compensation performance, otherwise it will be in the shaft, coupling, bearing design caused additional load, resulting in deterioration of the work.

Displacement types between the two axes are: axial displacement, Voss Push in Couplings radial displacement, deflection displacement and integrated displacement.

Fixed rigid coupling

1. Structural features

A. simple structure, easy maintenance, can pass a larger torque;

B. the lack of compensation for the relative displacement between the two axes that are coupled;

C. pairs of the two-axis on the high requirements, if the relative displacement of the two axes, will be in the shaft, coupling and bearing on the additional load and serious wear and tear, Voss Push in Couplings seriously affect the shaft and bearing the normal work; Passing loads can not mitigate shock and absorb vibration.

2. Application

Low speed, large torque, smooth load, short and rigid shaft connection

3. Category

Flange coupling and sleeve coupling two.

4. Flange coupling structure characteristics

A. Composition: two flanged half coupling and a set of bolts;

B. Principle of work: two with a flange of the semi-coupling keys are connected to the two shafts, and then bolts to connect the two semi-couplings together to transfer movement and torque.

C. on the way: 1, respectively, with the shoulder and groove of the two semi-coupling with each other to match the middle and semi-coupling with ordinary bolts; (by preloading ordinary bolt on the flange side Contact with the surface of the friction generated by the torque; with hinge hole bolt on the middle, by the screw to withstand the extrusion and shear transmission torque.) 2, two semi-coupling are made of shoulder, together with a split ring And to achieve alignment.

D. Applicable: low speed, large torque, smooth load, short and rigid shaft connection.

E. simple structure, transmission torque; reliable force, good for neutral; easy disassembly, Voss Push in Couplings widely used; but does not have the displacement compensation function; according to the standard selection.

5. Sleeve coupling structure characteristics

A. Composition: Connect the male sleeve to the two shafts via a key or pin connection.

B. Advantages: simple structure, easy manufacturing, low cost, radial size is small.

C. Disadvantages: need to move axially when loading and unloading.

D. occasions: two-axis diameter is small, the two-axis neutral high precision, smooth operation of the occasion, for the transmission torque is small occasions.
