本文介绍多驱动胶带输送机中间摩擦式驱动装置的几种不同结构特点及其合理的使用范围。驱动胶带只与输送机承载胶带的上分支(图1a)或下分支(图1б)接触的中间驱动装置,结构上最简单而又可靠。这类驱动装置具有一个单滚筒的驱动机,并根据驱动段长度的不同选用弹簧——螺旋式、重锤式 This article describes several different structural features of the multi-drive belt conveyor intermediate friction drive and its reasonable use of the range. The drive belt is only the simplest and most reliable construction of the intermediate drive in contact with the upper branch (Figure 1a) or the lower branch (Figure 1b) of the carrier tape. This type of drive has a single-cylinder drive machine, and depending on the length of the drive section selection of spring - screw type, hammer type
