    • A blade-type tensioner for chain drives which is suitable for use as a tensioner on the timing chain of a motor vehicle engine. The present invention is a chain tensioner particularly suited for use in confined spaces having a blade spring element mechanically interlocked with a plastic shoe. The shoe may be of rigid filled nylon and engages the chain to be tensioned. The spring element is interlocked to the plastic shoe by having ends inserted into grooves formed in the opposite ends of the shoe. The shoe is rotatably fixed to a base by way of a pin. The groove at the fixed end of the shoe extends towards the tip of the fixed end of the shoe past the pin attachment point. The groove at the free end of the shoe extends toward the tip of the free end of the shoe past the point at which the free end of the shoe bears upon a sliding surface formed on the base.
    • 一种用于链条驱动器的叶片式张紧器,其适合用作机动车辆发动机的正时链条上的张紧器。 本发明是一种特别适用于具有与塑料鞋机械联锁的叶片弹簧元件的密闭空间中的链条张紧器。 该鞋可以是刚性填充的尼龙并且与待张紧的链接合。 弹簧元件通过将端部插入形成在鞋的相对端中的槽中而与塑料鞋互锁。 鞋通过销可转动地固定在基座上。 鞋的固定端处的凹槽朝着穿过销连接点的鞋的固定端的尖端延伸。 鞋的自由端处的槽朝着鞋的自由端的尖端延伸穿过鞋的自由端承载在形成在底座上的滑动表面上的点。
