Abrasive grinding belt test machine
First Claim
1. An apparatus for measuring the normal and tangential belt forces between a belt and a driving pulley (contact wheel) as well as the workpiece grinding friction force between a workpiece and the belt, with respect to pulley angular position, for abrasive belt grinding, the apparatus comprising:
- an instrumented driving pulley (contact wheel) in which normal and tangential force transducers are assembled;
a first motor which rotates the said driving pulley;
a belt means connecting the driving pulley to a driven pulley whereby said belt means contacts the workpiece;
a second motor which rotates said workpiece and is mounted on first sliding means;
a first loading means connected to said first sliding means for applying a workpiece grinding normal force;
a second sliding means on which the driven pulley is mounted for driving pulley (contact wheel) belt grinding;
a second loading means connected to said second sliding means for applying the belt initial tension.

Abstract
A machine is presented for measuring normal and tangential belt forces as well as the grinding friction force all versus the angular position for abrasive belt grinding. Normal and tangential force transducers, having the same surface shape and surface finish as the contact pulley, are assembled in the contact pulley. The instrumented contact pulley is used as a driving or driven pulley. A variable speed D.C. motor rotates the driving pulley. A cylindrical workpiece is driven by a variable speed A.C. motor through a torque sensor. The torque sensor determines the grinding friction force between the workpiece and the belt. The A.C. motor-torque sensor assembly is mounted on a carriage plate which slides on two rails with linear bearings. Means are provided for applying a predetermined belt tension and means are also provided for applying a workpiece grinding normal force.
