The utility model discloses a special anti-backlash bearing system for a precision calender, which comprises a bolt hole, a bearing seat, a roller body, a bearing sleeve, a anti-backlash bearing sleeve, a sealed bearing and an end cover, and is characterized in that the bearing sleeve is composed of a plurality of single bearings. The lubricating oil channel is arranged on the bearing seat. Two through holes are arranged on the lubricating channel on the bearing seat. The clearance of the roller body is eliminated by screwing bolts in the bolt hole. The anti-backlash bearing system for the precision calender of the utility model applies an upward force to the roll body by setting bolt holes on the bearing seat and using the screw-in bolts, thereby offsetting the backlash produced in the production process and ensuring the calendering precision. At the same time, the lubricating oil channel is arranged on the bearing seat, and two through holes are arranged on the lubricating oil channel, which is convenient for supplying lubricating oil at any time, and prevents the roller body from being damaged during the rotation of the roller body.

技术介绍
压延机(calender)是由两个或两个以上的辊筒,按一定形式排列,在一定温度下,将橡胶或塑料压制展延成一定厚度和表面形状的胶片,并可对纤维帘帆布或钢丝帘布进行挂胶的机械。压延机按照辊筒数目可分为两辊、三辊、四辊和五辊压延机等;按照辊筒的排列方式又可分为“L”型、“T”型、“F”型、“Z”型和“S”型等。压延机由机架、压辊及其调节装置、传动系统和加热系统等部分组成,机架通常用铸铁制成,直接安装在铸铁或铸钢机座两侧,用以支承压辊轴承、轴交叉或压辊预弯曲装置、压辊调节装置、润滑装置和其它辅助装置。压辊由冷硬铸铁,铸钢制成,其长径比根据压辊材料的弯曲强度选定,约为2.6~3.5。为了补偿压辊受力产生的弯曲变形而造成制品厚度不匀的缺陷,压辊多制成腰鼓形,还可利用辊交叉装置和辊预弯曲装置消除制品的厚度不匀。现代压延机都使用滚柱轴承代替传统的滑动轴承、以节约能量、提高轴承寿命和制品厚度的精度。压延过程需要保证压延的精度,压延辊筒的在转动过程中,常常会产生晃动,这是压延辊筒在转 ...
