H P In Reliability

摘要

Good sheave alignment will increase efficiency by reducing premature wear or failure of belts, pulleys and bearings. This can be accomplished by several different alignment methods, such as the labor-intensive string and straightedge method (most common) or by laser. The letter, in the form of the DotLine Laser Pulley Alignment Tool (Fig. 1), is new to the sheave alignment field, but has proven itself in greatly reducing downtime and the manpowder needed to do the alignment. Simultaneously, it achieves far greater accuracy. This results in great labor savings and increased production uptime.
