滚筒不仅是带式输送机主要传动部件也是易损件，特别是在复杂恶劣的工况下，如何改进结构、提高工效、延长使用寿命，一直是研制人员所关注的课题。
设计中采用了轴固定于滚筒外支座上的结构，传动时只有筒体及轴承旋转，形成了主受力与传动部件分隔的传动系统。降低了整体运行阻力。在轴的设计中，将注油孔设置于轴端，通过轴身内部通道注入润滑油；轴外侧加无缝钢管轴套，轴套两端通过联接盘与铸焊接盘焊接，形成轴承、轴及密封件为一整体的密封系统。
特性：
(1)结构上很好地解决了大型滚筒组装时易使轴端与轴承配合错位引起轴阶与轴承内圈擦伤而影响零件使用寿命，装配浪费工时等问题。使用轴套组装能较好地对正，且安装方便。
(2)轴套与轴径向间隙为0.5—1mm，从轴端油杯处注油，使润滑油能充满轴套与轴的间隙，轴与轴套之间可形成吸附油膜能随时补充轴承及密封腔内的润滑油。经测试新型滚筒整体旋转阻力比普通滚筒降低40%左右。
(3)轴套做了耐腐处理，使筒皮内壁由于时效及外部侵蚀等怍用脱落的氧化物等杂质被隔绝于整个传动体系之外，大大延长了轴、轴承等传动零件的寿命，提高了滚筒的密封性。
(4)接盘采用铸焊结构，接盘与筒皮采用“U"形焊缝焊接。为保证铸胶附着强度，经试验合理的设计了筒体金属表面车削工艺螺纹，以保证其技术要求。

Belt conveyor roller is not only the main transmission parts and wearing parts, especially in the complex and bad conditions, how to improve the structure, improve work efficiency, prolong the service life, has been the research focus of researchers.
The design uses a shaft is fixed on the roller support structure, drive when only the cylinder body and the bearing to rotate, formed the main force and the driving components separated transmission system. To reduce the overall running resistance. In the design of shaft, the oiling holes are arranged on the shaft end, through the shaft body channel injecting lubricating oil; the outer side of the shaft and seamless steel pipe sleeve, at both ends of the shaft sleeve through a connecting disc with casting welding plate welding, forming a bearing, shaft and seal is a sealing system.
Characteristic：
(1) the structure well solves the large drum assembly is easy to make the end of the shaft and bearing misalignment caused by shaft and the inner ring of the bearing abrasion and impact of order of service life of parts, assembly waste hours of work and other problems. The use of shaft sleeve assembly can be effectively, and has the advantages of convenient installation.
(2) the sleeve and the shaft radial clearance of 0.5 - 1mm, from the end of the shaft oil cup oil, the lubricating oil can be filled in the gap of the sleeve and the shaft, shaft and the shaft sleeve can form between the adsorption of oil film bearing and seal cavity can at any time to add lubricating oil. By testing the new drum rotation resistance than ordinary roller is reduced by about 40%.
(3) Bush made corrosion treatment, so that the cylinder inner wall due to aging skin and external erosion Zun with shedding of oxides and other impurities were isolated in the whole transmission system, greatly extending the shaft, bearings and other transmission parts of the life, improve the cylinder seal.
(4) connected discs using cast weld structure, connecting plate and the drum skin by "U" shape weld. In order to ensure the rubber casting adhesive strength test, the reasonable design of the cylinder surface of metal cutting process thread, in order to ensure the technical requirements.
