Abstract:
1. A torque-limiting driver, comprising: a) a housing having a first proximal housing section with a drive end at which drive end a drive interface is disposed, and having a second housing section mechanically communicating with the first housing section by a housing coupling, the second housing section having a distal shaft end with a shaft port that is configured to receive a shank of a driver output shaft extending along a rotation axis of the driver; b) a wear-compensated torque-limiting assembly disposed within the housing and mechanically adapted to apply a torque from the drive interface with the driver output shaft, the torque-limiting assembly being adjustable to selectively set a calibrated maximum amount of torque that can be transmitted via the drive interface of the housing to the driver output shaft and comprising: c) a bearing load assembly in mechanical communication with the torque-limiting assembly and adapted to apply a bias force thereto to selectively set the calibrated maximum amount of torque that can be transmitted via the drive interface of the housing to a driver output shaft.
