Its behavior is either large or small on compared with theory value to holding the distance on the roller or edge of cylinder the edge of conveyer belt. The running and leaning towards and will enable conveyer belt and framework, ask the roller support to rub of conveyer belt, cause the glue is worn and torn. A serious one run, lean towards, can enable conveyer belt turn-ups, if surface edge have protruding screw head, cover glue layers of part strip, accident of scratching etc. in cylinder. Run, lean towards, can lead to the fact accident of conveyer shut down number of times increase, influence and produce; Run, may cause supplies let go also simply, make conveyer economic decline of operation of system. For this reason, it is the crank connecting rod organization that the crank connecting rod type adjusts and leans towards the most outstanding characteristic of the device automatically. Adjust and lean towards the shelf and install the connecting rod made of the symmetrical connection of both ends on the base through the rolling bearing, the connecting rod sets up the roller terminal fixedly. Both sides that are installed on the crank set up the roller close to the edge of conveyer belt, run and simply appear, conveyer belt press to should incline, set up roller, make, set up roller rotate outwards with the crank, the crank and connecting rod spur and adjust and lean towards the shelf to rotate certain angle according to the conveyer belt operation direction, thus produced and adjusted partially. 目 录1引言12系统分析22.1工作原理2 2.2初始条件22.3计算过程与分析22.3.1阻力计算22.3.2载荷计算32.3.3总阻力计算42.3.4弹簧弹力计算与选择42.3.5调偏架的固定52.3.6两连杆的固定及计算62.3.7其它杆件的安装62.3.8立辊的规格63系统说明74. 心得体会8参考文献8
