一、皮带输送机托辊的使用 1.托辊使用前应仔细检查外观有无严重磕碰受损现象，旋转托辊应转动灵活，无卡阻。 2.托辊的安装距离应视物流的种类和输送机特点运量大小经科学计算而定，避免过疏或过密安装。 3.托辊安装应适应避免相互间磨碰。 二、皮带输送机托辊的维护 1.托辊正常使用寿命20000h以上，一般不需维修。但根据使用场所和负荷的大小，应制定相应的维修日期，及时清洗注油维修，及时清理浮煤。对有异常声响和不转的托辊要及时更换。 2.更换轴承时，必须使轴承保持架开口向外，轴承装入托辊后，应保持适当的游隙，不得压死。 3.迷宫密封件应采用原厂配件，装配时应分别装入托辊内，不得套在一起装配。 4.使用中托辊，应严防重物击砸托辊管体。 5.为确保托辊密封性能及使用性能，禁止随意拆卸托辊。
The use of 1. roller before use should be carefully checked whether the appearance of serious damage phenomenon and supporting a bump, belt conveyor, roller rotation should be flexible rotation, no jam. The installation distance of 2. idlers should be determined according to the type of logistics and the characteristics of the conveyor, and the size of the traffic volume should be determined by scientific calculation, so as to avoid the installation of too sparse or too close. 3. roller installation should be adapted to avoid mutual grinding collision. Two, belt conveyor roller maintenance, 1. roller normal service life of more than 20000h, generally need no maintenance. But according to the size of the use of the site and load, should develop the corresponding maintenance date, timely cleaning oil filling repair, clean up floating coal in time. The idler with abnormal sound and no change should be replaced in time. 2. when changing the bearing, the bearing cage must be opened outwards, and the bearing should be kept in proper clearance after loading into the idler, so the bearing cage should not be crushed. 3. labyrinth sealing parts should be used in the original parts, should be installed separately in the idler, not assembled together. 4. the use of idler rollers, should prevent heavy objects hit the roller tube body. 5. in order to ensure the sealing performance and use performance of roller, it is forbidden to disassemble idler roller at random.
