摘要： 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.

摘要： A silent chain having multiple links each having a pair of teeth and apertures, which are connected by connecting pins inserted into the apertures. The links have an sheared link bearing surface which further reduces the wear of the sprocket tooth surface and further prevents defective bending of the silent chain. The bearing surface of the link tooth has a shear surface which may be formed by shaving or fine-blanking. The shear surface length may be at least approximately 70% or at least approximately 90% of the link thickness.

摘要： Chain parts and other steel articles are provided with hard, wear-resistant carbide coatings by tumbling them in a heated retort with a particulate mix which includes a source of vanadium and/or niobium. The steel substrate comprises a steel having at least 0.2% carbon, preferably 0.7-1.2%. Where the chromium content of the steel is 4-12%, preferably 4-8%, the chemical deposition process includes drawing a small amount of chromium from the steel substrate into the vanadium or niobium carbide coating, where it is distributed substantially homogeneously, helping to provide adhesion strength to the coating.

摘要： A blade tensioner is configured with a blade shoe having a chain sliding face, several plate-spring-like blade springs stacked on the reverse side of chain sliding face of the blade shoe in order to apply a spring force to the blade shoe, and spacer members provided between respective adjoining blade springs and brought in contact with corresponding blade springs at least at two points separated from each other by a fixed distance. In such case, the blade springs contact the spacer members at a fixed span. Accordingly, the damping factor of the overall blade spring or system is constant, so that the damping performance of the blade tensioner can be stabilized.
摘要翻译：叶片张紧器配置有具有链条滑动面的叶片靴，多个板簧式叶片弹簧堆叠在叶片靴的链条滑动面的相反侧，以便向叶片靴施加弹簧力，并且间隔件设置在各个邻接的叶片弹簧之间的构件至少在彼此分开一定距离的两个点处与相应的叶片弹簧接触。在这种情况下，叶片弹簧以固定的跨度与间隔件接触。因此，整个叶片弹簧或系统的阻尼系数是恒定的，使得叶片张紧器的阻尼性能可以稳定。
