Title: The Innovative Contributions of Donald R. Sherman
Introduction
Donald R. Sherman is a notable inventor based in San Jose, CA, who has made significant contributions to the field of wheel balancing technology. With a total of 4 patents to his name, Sherman has developed innovative solutions that enhance the performance and accuracy of wheel balancing machines.
Latest Patents
One of Sherman's latest patents is a transducer mount for wheel balancing machines. This invention features a transducer mount designed for machines that utilize a rotatively driven shaft to support a wheel/tire assembly. The design includes two spaced apart bearing blocks that support the shaft, which are mounted within a square passageway formed by a rigid structural member. The bearing blocks are dimensioned to create a gap between their peripheries and the walls of the passageway. Additionally, a passive support member and an active support member, which includes a piezoelectric element, extend between the passageway and each of the bearing blocks. This innovative design generates a voltage that represents the imbalanced forces in the wheel/tire assembly.
Another significant patent by Sherman is the wheel balancer transducer mount with an improved signal-to-noise ratio. This invention addresses the challenges faced by wheel balancers that have a shaft and a drive belt approaching the shaft from a specific direction. The design incorporates a bearing block supported by a passive mount aligned with the drive direction, along with an active mount spaced from the passive mount. This configuration ensures that vibrations from the belt drive do not produce moments about the passive mount that are sensed by the active mount, thereby enhancing the accuracy of the wheel balancing process.
