发明内容
从现有技术出发,本发明的目的在于提供具有可选结构的传感器单元。
为了实现该目的,本发明提供了一种传感器单元,其特征在于,该传感器单元具有容纳传感器构件以及至少一个电路板的环形的基体。由于不同的传感器装置的传感器构件以及具有用于这些传感器构件的电源和信号传输组件的电路板预先安装在单独的环形基体上并且相互适宜地连接,根据本发明的传感器单元可以快速且简单地在机械系统中进行安装,因为只有基体必须被装入。相应地,根据本发明的传感器单元的安装带有低的时间和成本耗费。
根据本发明的一个设计方案,不同的传感器装置具有至少一个温度传感器装置和/或至少一个转矩传感器装置和/或至少一个振动传感器装置。因此,可以利用单独的传感器单元来采集全部数据,尤其是对监控传动装置所必需的全部数据。
优选在基体上设有用于连接外部的电源和信号传输导线的可从外部触及的单独的接口。以这种方法,对根据本发明的传感器单元在将传感器单元连接至外部电源和信号评估装置方面的操作,得到明显改进。
有利地,作为传感器构件,至少一个温度传感器装置的测量量采集器和至少一个转矩传感器装置的测量量采集器位于基体的第一端侧处,并且电源和信号传输接口位于基体的相对的第二端侧处。相应地,在安装基体时,温度传感器装置和振动传感器装置的测量量采集器能够指向待监控的组件地定向,其中,例如其是传动轴承,同时在基体另一端侧实现电源和信号传输导线的连接。

根据本发明的一个设计方案,电路板位于基体内部中。电路板的这种设置的优点在于,使电路板免受外部影响。类似的,这适用于存在在传感器构件与电路板之间的布线。
基体优选由耐油、耐温和耐压材料制成,尤其是由塑料、优选聚酰胺制成。相应地,基体可以无问题地承受占据在传动装置或机械系统中的条件。材料的耐油性、耐温性和耐压性的程度可以分别根据有传感器单元集成在其中的机械系统的运行条件来确定。
根据本发明的一个设计方案,基体以增材的方式制成,这带来了在生产基体和传感器单元时的高灵活性。替选地,原则上也可以使用其他制造技术来生产基体。
此外本发明还提供了一种具有至少一个根据本发明的传感器单元的传动装置。
传感器单元的基体优选布置在传动装置壳体盖与在传动轴上布置的传动轴承之间,并且可以抵靠在这些传动组件上,尤其是在这些传动组件应该被重点考虑时。
优选地,作为转矩传感器装置的传感器构件,测量量采集器和信号发射器在基体径向内部设置在传动轴上,信号发射器将测量量采集器检测的测量数据传递至设在基体的内环周处的信号接收器。
本发明还提供了一种传动系,该传动系包括与传动装置以传递转矩的方式连接的转子轴,该转子轴又以传递转矩的方式与传动装置连接,其特征在于,该传动装置设计为根据本发明的传动装置。

图5示意性地示出了根据本发明的传动系26的另一实施方式的结构,该结构可以被用于未详细示出的风力发电设施22或未详细示出的工业应用28。传动系26包括根据本发明的被实施为行星变速箱的传动装置3,该传动装置在入口侧与风力发电设施22的驱动机构29或转子23连接并被供给有驱动功率30。在风力发电设施22中这借助于转子轴24完成。在此,传动装置3包括前后依次布置的行星级31、32和33以及端侧轮级34。传动级31、32、33和34将输出功率35输出给发电机25或机械应用36。

虽然通过优选实施例详细示出并描述了本发明,但本发明不由公开的示例限制,并且其他变型可以由领域内的技术人员推导出而不脱离本发明的保护范围。
