How To Eliminate Output Overloads and Maintenance In Your Index Table Applications
Output overloads or “overload clutches” have been used for decades to protect the internal mechanics of a rotary index table. Most index tables become vulnerable when a manufacturer specifies a motor that is more powerful than the internal cam followers, cam, and bearings can support. A larger horsepower motor usually requires the use of an external gear box or reducer. The utilization of these mechanical boxes introduces increased maintenance and a larger overall footprint of the table.
The robust mechanical design of the WEISS index table eliminates the need for an output overload clutch. We are the only index table company that does not offer an overload clutch due to our innovative design. Our tables are designed to withstand an unlimited amount of e-stop and jam occurrences. This is accomplished by not sizing a motor that is more powerful than the table’s extremely robust internal mechanical components. If a jam or e-stop occurs then the motor will stall before any mechanical components can fail. You simply release the brake on the motor and index to the next position after a jam or e-stop condition.
