The invention discloses a telescopic cylinder, the telescopic cylinder comprising an outer tube and an inner tube, the inner tube being at least partially disposed within the outer tube and being longitudinally displaceable within the outer tube along a stroke between a starting point of a stroke in which the inner tube is fully retracted into the outer tube and an end point of a stroke in which the inner tube is fully extended from the outer tube. The telescopic cylinder includes a guide ring disposed in a recess of an inner surface of the outer tube and configured to be in contact with an outer surface of the inner tube to align the inner tube within the outer tube throughout a stroke. The telescopic cylinder further includes a slider disposed in a recess in an outer surface of the innertube and a wear band disposed in a recess in an inner surface of the outer tube, where the slider and the wear band are configured to contact each other when the inner tube is at an end of the stroketo align the inner tube within the outer tube at the end of the stroke.
公开了一种伸缩缸,其包括外管和内管,该内管至少部分地设置在外管内,并且可以沿着一行程在内管完全缩回到外管内的行程的起点与内管完全从外管伸出的行程的终点之间在外管内纵向位移。伸缩缸包括引导环,该引导环设置在外管的内表面的凹部中,并且构造成与内管的外表面接触,以在整个行程中将内管对准在外管内。伸缩缸还包括设置在内管的外表面中的凹部中的滑动件以及设置在外管的内表面的凹部中的耐磨带,其中滑动件和耐磨带配置成当内管处于行程的终点时彼此接触,以在行程的终点处使内管对准在外管内。
