滚筒选用大无缝钢管直接制作：使用火焰切割机进行精确切割，使用专业滚筒焊接机对滚筒内圆盘进行焊接，使用变位机对滚筒轴套和圆盘进行焊接。用大车床进行滚筒外圆通加工，壁厚均匀径向跳动小。选用45#圆钢与轴套，轴通加工，保证轴的同心度和减少轴的偏心力。使滚筒转动更稳定，优质轴承和轴承座，配有轴承内径增大器，轴承为热装。可以轻松将轴承推到轴承位处，避免了敲打对轴承的损伤，当滚筒承受合力大于80KN的都做消除内应力处理，带速大于2.5m/s的需做静平衡检测。

The pulley directly was made by large seamless steel: We precisely cut the tube by using the flame cutting machine, and weld the inner pulley disc by using the professional pulley welding machine, and weld the pulley sleeve & disc by using the positioner. We use the large drum lathe process the outside circle, so that it ensures the pulley has the uniform thickness and small pulsation.We chose 45# round steel & sleeve and process the whole shaft so that it ensures shaft concentricity and reduction for the eccentric shaft force. It make sure the pulley move more stable, high-quality bearing which is hot charging and bearing block are equipped inner bearing Enlargement Device, so the bearing can be easily pushed to the bearing position and it avoids the bearing damage from the beating.We need make the eliminating inner stress treatments when the pulley's withstand forces exceed 80KN and we will make the static balance inspection when the belt speed exceeds 2.5m/s.

可以根据不同客户的要求加工定做不同型号、不同质量、不同标准的各种滚筒。

We can produce different type, different quality, different standard pulleyaccording to the customers request.

可生产不同国家标准的滚筒：生产范围直径巾219mm-巾3000m，长度500mm-5000mm

Producing different standards pulley: Production scope Diameter:b219mm-中3000m, Length:500mm-5000mm
