Overhang Loads | | When attaching a chain sprocket or V-pulleys to the output shaft, the overhang load must be taken into consideration. Allowable overhang loads are shows in the following table. | |
[Formula to Determine Overhang Load] | Allowable overhang load | Overhang load = T x H x S / R | T | = | Torque x service factor | S | = | Position factor | H | = | Overhang load factor | R | = | Radius of pitch of sprocket wheel or pully | | | |
Chain | 1.00 | | | Gear | 1.25 | | V-Belt | 1.50 | | Flan belt | 2.50 | | | | | |
if overhang load value does not satisfy the above formula, increase R (i.e. radius of pitch of sprocket wheel, gear or pulley).
1) l ? L/s (when load is at middle or inner side) S = 1 2) l > L/s (when load is at outer side) S = 2 l /L |
