T***预张力预紧力对整个传动装置的运行状况和寿命有很大的影响。因此，它是少数几个变量的牙齿皮带驱动器的用户必须为自己设置。预张力取决于齿带传动的几何形状和应力。理想的传输行为、******和重复精度只能在特定的预张力下实现。全电子测量仪能方便、安全地设定齿带传动的预紧力。特殊传感器记录已安装的齿带的振动。仪器记录皮带的工作频率。光不敏感传感器允许传感器和皮带之间相对较高的测量距离。出于这个原因，该仪器非常适应生产和安装/装配条件。利用弦振动的基本物理原理，皮带的预张力和工作频率相互关联。因此，根据测量的频率来计算皮带的预张力是一项快速而容易的任务。Pre-tensionPre-tensionhighlyinfluencestheoperatingconditionandlifeofthewholegearing.Itisthereforeoneofthefewvariableswhichtheuseroftooth-beltdriveshastosetforhimself.Pre-tensiondependsonthegeometryandthestressofthetooth-beltdrive.Thedesirabletran***ittingbeh***iour,precisepositioningandrepetitionprecisioncanonlyberealisedataspecificpre-tension.Thefullyelectronicmeasuringinstrumentenableseasyandsecuresettingofthepre-tensionintooth-beltdrives.Specialsensorsregisterthevibrationofatooth-beltthathasbeensetinmotion.Theinstrumentregistersthebelt’soperatingfrequency.Thelight-insensitivesensorsallowforarelativelyhighmeasuringdistancebetweenthesensorandthebelt.Forthisreasontheinstrumentisverywelladjustedtoproductionandinstallation/assemblyconditi***.Usingthebasicphysicalprincipleofastringvibration,thepre-tensionandoperatingfrequencyofthebeltarerelatedtooneanother.Itisthereforeaquickandeasytasktocalculatethebelt’spre-tensionaccordingtothemeasuredfrequency.)
