Rotary damper gear precision torque characteristics

Requirement

A global manufacturer and distributor of component parts that are used in products across many industries, including transport, beauty, consumer goods, and healthcare, came to Mecmesin with a challenging torque measurement application.

Their division in Thailand was manufacturing a new design of small rotary damper gear for their own customer.

To enable the development of the product, specific performance targets had been set and there was a requirement to measure and report of the torque-to-turn characteristics of the gear.

The very light torque values involved with such a small component needed and instrument with appropriate accuracy and sensitivity in order to provide meaningful data for confident comparison of differences from sample to sample.

Solution

Mecmesin Asia supplied a Helixa-i precision torque testing system, which is built to measure down to mN.m values with high accuracy - facilitated by precise and adjustable axial alignment of the rotational axis.

The Mecmesin engineers modified the motor drive to increase its standard speed to 100 rpm maximum; a specific requirement of the customer's test procedure.

In addition, a bespoke fixture was designed to support the damper gear sample.

Helixa-i is computer-controlled by Emperor Torque software, which allows the user to write flexible and unique test programs, store them in a library of procedures and run them against any design variant or development sample.

This in-house R&D capability to apply any test condition will boost the efficiency of the new product development cycle.

Test equipment

  • Helixa-i precision automated torque testing system with modified motor speed control
  • 0.1 N.m Helixa Torque Cell
  • Special damper gear holder fixture

PC-driven
Helixa-i

The Helixa-i is a top of the range torque tester controlled by software running on a PC. Designed for precision torque applications where torque forces may be very small and accuracy is the priority.

With a wide range of precision fixtures, the Helixa-i is easy to use and optimised for measuring torque from as little as 1 mN.m right up to 6 N.m.
