Precision And Flexibility For Demanding Drive Systems

DESCH flexible couplings are designed to transmit torque while accommodating shaft misalignment, vibration and shock within industrial drive systems. With multiple coupling designs, materials and performance ranges, DESCH provides solutions for applications ranging from compact, high-speed drives to heavy-duty systems requiring high-torque transmission. Depending on the coupling design, options include aluminum, steel and grey cast iron construction, as well as flexible tyre couplings for applications requiring substantial misalignment compensation.

Choosing The Right Coupling For The Job

There’s a lot to consider when choosing the right DESCH product for your specific application.

Load & Speed

The coupling must be matched to the torque and rotational speed of the connected equipment.

Key factors to assess include:

  • Peak and starting loads
  • Required safety factor
  • Drive duty cycle

Alignment & Vibration

Shaft misalignment, vibration and shock can place additional loads on connected drive components.

When evaluating, consider:

  • Radial or parallel misalignment
  • Axial movement
  • Vibration levels

Application & Configuration

Material, available space, shaft dimensions and required torque all influence the final configuration.

Our options include:

  • Flexible tyre designs
  • Compact mini couplings
  • Application-specific configurations

Maintain For Longevity

While DESCH products are engineered for long-term performance, appropriate maintenance helps protect reliability, extend service life, and prevent avoidable downtime.

  • Install and align the coupling according to the specified installation requirements
  • Verify operating torque and speed remain within the coupling’s rated limits
  • Inspect flexible elements and connection components during scheduled maintenance
  • Monitor for abnormal vibration, noise or changes in operating conditions
  • Replace wear components when inspection indicates deterioration
