带式输送机搭接存在的问题及影响托辊的因素
Problems existing in lap joint of belt conveyor and factors affecting idler
带式输送机在长距离直线运输中的确能发挥重要作用，但在拐弯的运输巷道中运行，就难以满足运输需求了。大型钢丝绳缠绕多驱动带式输送机的运输距离，一般也都是不大于两千米。一般可弯曲带式输送机，则是无法实现小角度运输的，必须采用搭接方式来解决转弯问题。转弯的输送机，容易抛落物料，会对下部的胶带产生较大的冲击力，使得下部胶带要承受连续或脉动的冲击，导致使用寿命降低，托辊的维修率被增加。从现场中发现，托辊轴承则是影响托辊寿命的主要因素。而轴承的寿命主要取决于所承载的荷载、质量和润滑状况。长期处在恶劣环境中运行的检查井钢模具 隔离墩模具 隔离墩钢模具 流水槽模具 U型槽模具 螺杆启闭机 卷扬式启闭机 铜雕佛像 轴承，多因素加剧磨损，大大降低了托辊使用寿命。
Belt conveyor can play an important role in long-distance straight-line transportation, but it is difficult to meet the transportation demand when running in the turning transportation roadway. The transportation distance of large wire rope winding multi drive belt conveyor is generally no more than 2000 meters. Generally, the bending belt conveyor is unable to realize small angle transportation, so it is necessary to adopt lap joint method to solve the turning problem. Turning conveyor, easy to throw materials, will have a greater impact on the lower belt, making the lower belt to withstand continuous or pulsating impact, resulting in reduced service life and increased maintenance rate of idler. It is found that the roller bearing is the main factor affecting the service life of the roller. It depends mainly on the condition of the bearing, the condition of the load and the life of the bearing. Bearing running in harsh environment for a long time, many factors aggravate wear and greatly reduce the service life of idler.
