Introduction: how to transform to the roller bearing parts - bearing knowledge

In 1995, our factory bought eight FA251C model combing machine, using often cause the clamp plate to roller bearing fault. Analysis of reasons, mainly manifested in the following two aspects. ( 1) Feed roller around the flowers. Due to cotton dust, rust or other reasons, mesa roller automatic stop device poor contact or unresponsive, feed roller after around the flower can't stop; In addition, the replacement of varieties from quantitative change, small volume table roller automatic stop contact height adjustment is undeserved, can cause feed roller around flowers don't stop. As the feed roller around the flower diameter increasing, feed roller bearing force is also increasing its fracture. ( 2) The clamp plate forget to reset. When the feed roller around the flowers stop, machinist must open the clamp plate to around flowers, the processing after processing if forget to reset the clamp plate on, boot after moment would be caused by the feed roller bearing fault. FA251C type comber clamp plate adopt aluminum alloy under the whole casting, welding method is used after damage can't restore to the original size, after the assembly stress non-uniform, soon break again, finally had to update. A new value 900 yuan, clamp plate under higher cost consumption. After an analysis of the causes we in March 2002, in the upper and lower clamp plate with a micro switch, as shown in figure 1, figure 2, the micro switch automatic system connect with the host. Around the flowers stop feed roller of the micro switch is installed on a clamp plate, Laura around the flower pin micro switch and downtime; Clamp plate forget reset can't boot micro switch is installed on the wallboard, forget to reset the clamp plate combined with a pressure micro switch and can't boot, clamp plate properly reset to boot. After adding micro switch, our factory caused by these reasons thoroughly eliminate clamp plate fracture, effectively reduce the equipment maintenance cost.
