一、原油路存在的问题中小型磨床工作台的导轨,大多采用图1所示的润滑方式。液压系统的压力油,经G节流减压,并由螺钉a调整压力后。再经可调节流器S_1及S_2,分别进入床身平V导轨中段位置的出油孔,然后通过工作台导轨上的油槽,润滑导轨。此种润滑方式可分为压力润滑和卸荷润滑两种,各存在一些缺点:
First, the crude oil road problems Small and medium-sized grinder table rails, mostly using the lubrication shown in Figure 1. Hydraulic system pressure oil, throttling decompression by G, and after a screw to adjust the pressure. And then through the adjustable flow control S_1 and S_2, respectively, into the middle of the bed flat V rail outlet hole position, and then through the slot on the table guide rail lubrication. This lubrication can be divided into two types of pressure lubrication and unloading lubrication, there are some disadvantages:
