Txawm hais tias cov haujlwm ntawm linear optical axis thiab cov lus qhia linear zoo sib xws, lawv yog ob qho tib si txhawb nqa thiab kev taw qhia, tab sis tseem muaj qee qhov sib txawv ntawm lawv, feem ntau nyob rau hauv qhov chaw teeb tsa thiab cov duab. Los ntawm cov duab taw tes ntawm view, linear optical axis yog ncig; thaum cov lus qhia linear feem ntau yog square thiab muaj txoj haujlwm ruaj khov uas cov slider tau ua tiav.
From the installation point of view, the linear optical axis is generally fixed at both ends, and the suspended connecting parts in the middle cover all or most of the radial direction of the optical axis; but the linear guide rail is generally close to the equipment installation base on one side and fixed by bolts. of.
After reasonable cooperation, the linear bearing embodies the characteristics of light weight, corrosion resistance, interchangeability, and low cost. It is widely used in various machine equipment and can achieve the greatest economic benefits of labor saving and automation. Precision equipment or special machinery industries such as electronic equipment, food machinery, packaging machinery, medical machinery, printing machinery, textile machinery, machinery, instruments, robots, tool machinery, CNC machine tools, automobiles, and digital three-dimensional coordinate measuring equipment will use straight lines. Bearing.
In order to meet the needs of these different applications, the linear bearing specifications are also diverse, basically covering the LM and LME, LIN-11, LIN-12, and KH series. Among them, the LM series takes the metric size as the standard, and the linear shaft is equipped. The outer diameter tolerance is generally h7; while the LME series adopts inch sizes as the standard, and there are also metric sizes. The outer diameter tolerance of the linear shaft is generally g6.
The LIN-11 linear bearing is a European standard plastic linear bearing, which is installed with a circlip limit; and the LIN-12 series is a narrow design, and its outer diameter is directly installed in a tight fit with the mounting seat hole, mainly for saving Installation space.
