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 錄1引言12系統(tǒng)分析22.1工作原理2 2.2初始條件22.3計(jì)算過程與分析22.3.1阻力計(jì)算22.3.2載荷計(jì)算32.3.3總阻力計(jì)算42.3.4彈簧彈力計(jì)算與選擇42.3.5調(diào)偏架的固定52.3.6兩連桿的固定及計(jì)算62.3.7其它桿件的安裝62.3.8立輥的規(guī)格63系統(tǒng)說明74. 心得體會8參考文獻(xiàn)8
