Refer to Instruction manual.<br />

A. Mounting - Sprockets, sheaves, gears and pulleys on<br />

output shaft.<br />

In general, the closer a sprocket, sheave, gear or pulley<br />

is mounted to the supporting bearings of an output shaft,<br />

the less will be the load on the bearing and the less<br />

the stress on the shaft.<br />

The overhung load capacities given below are calculated<br />

on the basis of the load being located one shaft diameter<br />

from the bearing housing. Make sure that the overhung<br />

load capacity of the output shaft is not exceeded.<br />

B. Determining Minimum Pitch Diameters for Connecting<br />

Drives<br />

When the type of drive load connection is a chain and<br />

sprocket, it is necessary to be sure the sprocket<br />

pitch diameter is adequate. Sprockets of<br />

small pitch diameter produce greater overhung loads than<br />

do larger sprockets. The same applied to other types<br />

of drive load connections, i.e., sheaves, gears or pulleys.<br />

REEVES<br />

The following formula may be used to calculate the<br />

minimum allowable pitch diameter (min. P.D.) of the load<br />

connecting device.<br />

Min. P.D. =<br />

Maximum output HP X F X 126,000<br />

Allowable overhung load X Max. output rpm<br />

Where:<br />

F = Factor for type of load connecting device<br />

Such as:<br />

F = 1 for chain and sprocket with one side tight,<br />

F = 1.25 for chain and sprocket with both sides tight,<br />

F = 1.25 for gear,<br />

F = 1.5 for V-belt and sheave with drive and driven<br />

sheaves of equal diameter,<br />

F = 1.5 to 2 for V-belt and sheave with drive and driven<br />

sheaves of unequal diameter,<br />

F = 2.5 for flat pulley and flat belt.<br />

Use allowable overhung load capacity for appropriate<br />

MOTODRIVE and reducer from tables below.<br />
