我厂铸造车间135m~3轨道式烘炉的台车轮架,原为固定穿孔式结构。在长期受反复高温烘烤和重力摩擦作用下,致使滚轮及滚轮轴磨损氧化严重。一般在2～3个月就要进行一次维修和保养,2～3年更新滚轮和滚轮轴一次。但穿孔式结构轮架给维修带来很大的困难。为解决此问题,我们将轮架改为如图所示的叉式 I plant casting workshop 135m ~ 3 track oven trolley frame, the original fixed-perforated structure. In the long-term by repeated high temperature baking and gravity friction, resulting in roller and roller shaft wear oxidation serious. Generally 2 to 3 months to be a maintenance and repair, 2 to 3 years to update the roller and roller shaft once. However, the piercing structure of the wheel frame to repair caused great difficulties. To solve this problem, we will change the wheel frame as shown in the fork
