|<b>David Brown Ratings and Service Factors</b>
Gear unit selection is made by comparing actual loads with catalog ratings. Catalog ratings are based on a standard set of loading conditions, whereas actual load conditions vary according to the type of application. Service Factors are therefore used to calculate an equivalent load to compare with catalog ratings.
i.e. Equivalent Load = Actual Load x Service Factor
<b>Mechanical Ratings and Service Factor Fm</b>
Mechanical ratings measure capacity in terms of life and/or strength, assuming 10 hr/day continuous running under uniform load conditions.
Catalog ratings allow 100% overload at starting, braking, or momentarily during operation up to 10 hours per day.
The unit selected must therefore have a catalog rating at least equal to half the maximum overload.
Mechanical Service Factor Fm (Table 1) is used to modify the actual load according to daily operating time, and type of loading.
If overloads can be calculated, or accurately assessed, actual loads should be used instead of Fm.
For units subjected to frequent stop/starts or overloads in excess of 10 times/day multiply factor Fm x Factor Fs (Table 2).
For applications where units are to operate in extremely dusty or moist/humid atmospheres, unit selection should be referred to Textron Power Transmission application engineers. |
