Durable Couplings

Ensure that your power is transmitted effectively at your facility or oil and gas site with devices from Lyle Dingman Company. Our versatile diaphragm couplings and torsional couplings provide you with the secure connections you need for two shafts. Use of these couplings allows rotating equipment to perform optimally.

VOITH BHS Diaphragm Couplings

Even if you are familiar with rotating equipment, you may require help selecting products. We are a manufacturers' representative for Voith BHS, which has 85 years of coupling experience. Voith engineers will find the right solution for your application. Available options include:

Special Purpose Couplings

API 671 Special Purpose Couplings

  • High reliability, wear-free, economical couplings
  • Light coupling for best rotor dynamics
  • Definable low axial loads and less restoring forces / important for high-speed gearing with double helical teeth
  • No friction within the coupling so no self-exciting vibrations (disc couplings)
Twintors Diaphragm Coupling

Innovative and Unique Twintors Diaphragm Coupling from Voith

  • Superior coupling choice for laterally sensitive gears and compressors requiring a low moment design coupling
  • No large disc bolts
  • No major diameter flange bolts
  • Small bolts used in flange connections
  • Exceeds design performance of industry-standard "RM" designs for disc couplings

General Performance Envelope

  • MAX Nominal speed 80,000 RPM

Voith Torsional Couplings

"Voith has more than 40 years' experience in developing Flexible Couplings to improve drive systems that are subjected to torsional vibrations, focusing on optimum service life of all drive components and connected equipment."

When you invest in torsional couplings from Voith, you receive:

  • Flexible & Highly Flexible Couplings
  • Torsional Vibration Calculations (TVC)
  • Torsional Vibration Measurement & Analysis (TVM/TVA)
Voith Torsional Coupling

Torsional Vibration Analysis (TVA)

A system's complete TVA looks at Natural Frequencies and Modes, Forced Vibrations (Excitation Frequencies), and Transient Conditions. A TVA tells you the amplitudes of the vibratory torques, power loss, angular accelerations, b.j.c., etc., within the RPM range of interest. Components are modeled as masses (inertias) connected by stiffness and damping values. This model is known as a "Mass Elastic System."

Torsional Vibration Analysis

Mass Elastic System

In the Voith TVA, complete Natural Frequency, Steady State, and Transient results are shown in detail (Campbell Diagrams etc.). Voith also provides a report that includes:

  • All Relevant Assumptions
  • Basic Application Parameters
  • Calculated Loads vs. Permissible Loads
  • A summary of the operation of the driveline, including any recommendations for improvement*

*NOTE: Most current coupling/TVA suppliers publish the results, without a summary of the important findings, and expect the customer to interpret the results themselves!
