Torque Inspector II Bench Top System

Torque Inspector II

Testing Capabilities

Both starting torque and running torque can be measured with the same system, the same tooling and in the same test cycle. From this testing a variety of problems can be identified.

  • Contamination
  • Material Defects
  • Surface Wear
  • Poor Internal Geometry
  • Structural Defects

Customized reports that show only the required information for a particular customer or a specific application can be easily generated, viewed on the screen and outputted to a conventional printer or strip chart printer.

The Torque Inspector II is a bench top system for measuring the torque characteristics of anti friction devices and assemblies. Contained in the system are a customized computer, monitor, keyboard, and the necessary circuitry for performing a test and processing the results. User-friendly menus enable the operator to rapidly become proficient with the operation of this National Instruments Labview based system.

Standard features such as 2 serial ports, one parallel port, four USB ports and a CD/DVD drive are provided.

Test configurations are stored in memory and are retrievable with the click of a mouse key, avoiding time consuming setups. Test results can be stored in memory or on a disk and then transported to other peripheral devices for further analysis and processing.

  • System Description

    This state-of-the-art computer and test head makes performing tests as easy as 1, 2, 3.

    The Torque Inspector II System consists of a state-of-the-art computer and a Standard, or High Load, Bearing Test Head. The test head contains a Vibrac Torque Transducer, an Optical Encoder and a Variable Speed Drive. This design enables the system to rotate the device under test at a constant speed (0.5 to 10 rpm) while measuring both torque and position.

    Test Head: A Vibrac Model 9405A test head is the mechanical testing portion of the BRG 3000 Bearing Test System. This test head combines an Optical Torque Transducer, an Optical Encoder and a Variable Speed Synchronous Drive. This combination enables the system to rotate the bearing at a constant and precise speed while measuring both torque and position.

    Torque Transducer: A Vibrac Mini Series Static torque transducer is used in this test head. The principal of operation for these torque transducers is pictured below.
