Adapters for Power Tool Testing
Like any other torque tool, power tools need to be tested. How they are tested has some significant differences than with other torque tools. The reason for the difference is that power tools move at faster rates of speed. It takes time to overcome inertia and get the fastener moving and it takes time to slow it down. Another difference is that power tools require filters to block out noise in the frequencies. SR digital torque testers have ten resident filters to help improve accuracy of power tool testing.
Rundown Fixtures assist in testing the output of pulse, stall and clutch power tools. Neither our testers nor our rundown fixtures are designed, engineered, or suited for impact tools. Testing impact tools on our equipment can damage the torque tester and immediately voids the warranty. Testing pulse and clutch power tools are accomplished by allowing the tool to achieve rotational speed prior to torque measurement. The rundown fixtures all include components to emulate either a hard or medium joint, thus assuring greater test accuracy.
The Rundown Fixtures work with Sturtevant Richmont System 4, System 5, System 8®, and Torq-Tronics®. Both Torq-Tronics 2 and the System 8 digital torque testers have power tool testing filters built. Matching tool capacity, rundown fixture capacity, and the transducer capacity is the basis for creating accurate test results.
Power tools are generally accurate 10% to 100% of rated capacity. In selecting a run down fixture match tool capacity with the rundown fixture kit. Example: If you have a 150 Nm or even a 200 Nm power tool you would select the 204 Nm run down fixture. When repairing the run down fixture be sure to match the repair kit capacity to the power tool capacity.
RDF Repair Kits
Each Rundown Fixture Repair Kit is the complete parts replacement for your fixture. With the included parts you can create a test to evaluate medium and hard joints. The kit includes the appropriate number of Bushings, Washers, Screws, Belleville Washers, Washers, and Power Bits for the corresponding fixture. Not all kits contain a power bit.
Note: When replacing parts in your Rundown Fixture be sure to replace ALL the parts and not just the part that may be worn out. In the long run the complete replacement approach saves time, headaches and ensures greater test accuracy. (Note: Each repair kit contains parts for 2-3 replacements.)
