Description

一种皮带机张紧机构
所属技术领域
本实用新型涉及一种皮带张紧机构，体积小、张紧力大。 
背景技术
目前，公知的皮带机张紧机构是由滚筒、行星减速器、异步电动机、液压制动器、轴承支座和底板装配而成。但是，由于液压制动需要额外的液压系统以及动力系统作为支持，需要额外空间进行安放。并且异步电机的体积相比同功率转速下的永磁同步电动机体积大。 
发明内容
本实用新型提供一种张紧机构，结构为联轴器、行星减速器、永磁同步电机、失电制动器、旋转变压器顺序连接，其特征是，联轴器将轴承与行星减速器的输出端相连接，行星减速器的输入端与永磁同步电机相连接，同时永磁同步电机与失电制动器相连接，在永磁同步电机轴末端与旋转变压器相连接，永磁同步电机作为系统动力装置。将行星减速器与联轴器的连接顺序互换，形成另外一种新的张紧结构。 
传统张紧机采用液压制动，制动滞后，对整体皮带机的灵敏性影响较大。本实用新型解决其技术问题所采用的技术方案是：将变频永磁同步电机以及电磁制动器集成于整个张紧机构当中，实现动力输出以及控制的一体化设计。采用了失电制动器，便可将液压制动进行替换，能比液压制动更快速的实现制动以及电机运行状态之间的切换。同时，电磁制动系统更节约空间。永磁同步电机比异步电动机的功率密度大，所需安装空间较小。 
本实用新型的有益效果是，可以在有限空间完成安装，同时控制反应速度更加快速，实现方式简单。 
附图说明
下面结合附图和实例对本实用新型进一步说明。 
图1是本实用新型的结构图。 
图1中： 
1为支座              2为球面调心滚子轴承  3为联轴器            4为滚筒 
5为行星减速器        6为轴承座            7为球面调心滚子轴承  8为轴承座 
9为支座              10为永磁同步电机     11为失电制动器       12为旋变 
具体实施方式
以下结合附图和实例对本实用新型进一步说明。 
在图1中，状态信号控制控制电机以及11失电制动器通电，电机正常运转，通过5行星减速器将高转速小扭矩转化为大扭矩小转速输出，通过3联轴器与4滚筒相连，保证力矩稳定输出。当张力足够时，状态信号控制切断电机以及失电制动器电源，保证失电制动器处于制动状态。整体系统在新的工况下进行工作。一旦出现故障，状态信号或者意外情况停电，电机与失电制动器会同时切断电源，保证系统安全。
