摘要： PROBLEM TO BE SOLVED: To solve the problem that in the conventional belt driving units a load is generated by sliding friction between a roller outer surface and a belt surface when a roller shaft displacement member displaces, and a contact stress is generated on the periphery part of an endless belt, which makes the lifetime of the endless belt shorter.SOLUTION: A tension roller 43 is divided into multiple segmented rollers from 43-1 to 43-5 in the axial direction in such a manner that each segmented roller 43-1 - 43-5 can individually turn. Thus, the tilt loading of the tension roller 43 caused by friction between the surface of the tension roller 43 and the inner peripheral surface of the intermediate transfer belt 41 is mitigated, which allows smooth movement of the tension roller 43. As a result, the effect that contract stress generated between the peripheral part of the intermediate transfer belt 41 and the side face of a pulley 56 is reduced is obtained and the extension of the lifetime of a belt unit 40, or an endless transfer belt, is expected.
摘要翻译：解决的问题为了解决传统的皮带驱动单元中当滚子轴位移构件移位时通过滚子外表面和皮带表面之间的滑动摩擦而产生负载的问题，并且产生接触应力环形带的周边部分，使得环形带的寿命更短。解决方案：张紧辊43沿轴向被分割成43-1至43-5的多个分段辊，使得每个分段辊43-1至43-5可分别转动。因此，由张力辊43的表面与中间转印带41的内周面之间的摩擦引起的张力辊43的倾斜载荷被减轻，这允许张紧辊43的平稳移动。结果，可以获得在中间转印带41的周边部分和带轮56的侧面之间产生的收缩应力减小的效果，并且期望带单元40或环形转印带的寿命延长。版权所有（C）2012，JPO＆INPIT
