| 摘要： | Overtightening a threaded stud will stretch it, distorting its shape and increasing the risk of fatigue cracking. Undertighte,ning the connection means the fastener is not exerting sufficient clamping force, making the wheel wobble and fretting the threaded wheel studs. Defending against this risk is the king of hand tools, the torque wrench, which applies the torque required, and indicates it to the user in some way. It allows technicians to apply the precise values specified by commercial vehicle OEMs. Like any precision tool, the performance of any of these torque devices can drift, and so they need regular checks and calibration to make sure they remain accurate. In addition, the IRTE Workshop Accreditation scheme, which audits workshops for expected standards, looks for confirmation and logging of calibration processes ensuring they have been taking place and are up to date, points out IRTE's John Eastman. |
