Sheave Alignment and Maintenance
Alan Luedeking of Ludeca Inc.
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 latter, in the form of the DotLine LaserTM Pulley Alignment Tool, is new to the sheave alignment field, but has proven itself in greatly reducing downtime and the manpower needed to do the alignment, while simultaneously achieving far greater accuracy. This results in great labor savings and increased production uptime.
The Expected and the Unexpected
The Ever Increasing Benefits of Modern PdM Technologies
by Bill Hillman, CMRP
When dial indicators, straight edges, and taper gauges were the only tools available for doing shaft-to-shaft alignment, machines were often left in a rough alignment condition. This happened because either too much time would need to be invested in order to obtain the required degree of precision or human error entered into the calculations.
The Impact on Bearing Life of Overtensioned Belts
by Jeremy Davis and Hunter Golden
One of the leading causes of premature bearing failure can be attributed to overload and overstress conditions. A common catalyst for this type of condition is improper belt tensioning. Increasing the radial load on a bearing will drastically reduce the expected bearing life span and can be graphically illustrated as y=1/x (0<x<infinity). In order to achieve optimal design expectations, procedure based, precision maintenance practices must be utilized.
