Know Everything about Gear Couplings

In mechanical power transmission gear coupling is a popular form of flexible coupling. What has made them one of the most preferred types of mechanical power transmission couplings is their suitability to a wide application like usability, areas & easiness in installation. Basically, between two connected shafts, they form a mechanical device that has a high capacity of transmitting 'torque', which is not collinear.

In performance they are considered as torsional rigid, their basic design can be divided into two major types:

Two external gear hubs are present in a fully flexible type coupling usually with finished bore & keyway mounted on connecting shafts. With internal teeth of common teeth are engaged in these hubs, which form a spline-like joint for power transmission.

2 halves, rigid and flexible are therein a semi-flexible coupling primarily. One end rigidity does not accommodate the parallel displacement of shafts but since it has flexible members; it surely does accommodate angular misalignment. This type of coupling is primarily employed in floating shaft applications.

In finished bore usually, a gear coupling from gear coupling supplier is supplied & installed & keyway conditions with specified dimensions against the requirement of the application.

What makes them suitable for a wide range of mechanical power transmission applications is the flexibility to absorb misalignment between 2 shafts, torsional rigidity, ease in installation & maintenance & most importantly high torque transmission capacity at low vibrations.

In design gear, teeth of the coupling is crowned which gives you the scope for absorbing angular misalignment while the scope for adjusting the linear misalignment is provided by the backlash between the mating teeth, which in turn makes the join, vibration-free during rotation.

Seals, machines, bearings, and shafts are therefore not subjected to the additional forces as large axial moments are avoided, sometimes of considerable magnitude.

There is extensive use of the gear couplings from gear coupling manufacturer in majority application areas such as heavy gearboxes, transmission drives, engines, fluid couplings similar where high torque transmission capacity along with torsional rigidity is required.

How to Choose the Right Conveyor Chain for Your Application

For the maximum performance of a conveyor chain, four critical criteria are required. They are wearing ability, impact resistance, and ultimate strength and fatigue resistance.

The measurement that determines the ultimate strength of the conveyor chain is the weight in pounds required to break the chain on a linear plane. By using a tensile testing machine the usual method of testing is done. ANSI dictates the minimum strength values for each size of the chain.

The material by which the chain is made, its hardening specifications, and its manufacturing process that is used in making its components consist of a pin, center link, and side link is controlled by the manufacturer and determines the strength of the chain.

While comparing chains a conveyor chain's durability value is the most subjective value to consider. Its durability is affected by factors such as chain speed, lubrication, loads, and system design among others. Only the hardness factor is controlled by a manufacturer that impacts the other three criteria.

It is a fact that the durability the factor of a chain from conveyor chain manufacturer depends on how hard the chain is but along with this comes to lower resistance to fatigue and impact. The more the chain is harder the less resistance it becomes to fatigue and impact.

While the chain is moving around its horizontal turns, the side loads between the chain and the rollers or traction wheel make for a subtle bending motion in the center link of the conveyor chain. For fatigue, this particular movement is the catalyst. The fatigue should not go unnoticed and therefore, hence the chain is not replaced at once and the instance of failure is diminished.

In the case of loads that are often stopped and started, the chain particularly the pusher dog is subject to impact failure if an impact-resistant material was not used in its manufacture. The loading and unloading sites are other possible points of impact on a conveyor from the conveyor chain supplier. Impact failures happen with no warning like fatigue failures, but they do not, as a rule, spread out as the fatigue failures do.
