Amerigear Engineering Data
Speeds, Classes and Balance
Speeds: The speed limits shown in the table are recommendations based on experience and are intended as a guide only. The actual limits are determined by the characteristics of the system in which the coupling is to be installed. Consult Ameridrives for speed limits of series not listed.
Classes: Four classes of Amerigear couplings are available.
1. Standard Amerigear Couplings
I. Standard Couplings
II. Balanced Standard Couplings
III. Class III Couplings
The hubs and sleeves of the Class III couplings are selected from stock to minimize gear tooth tip clearance, and the sleeves incorporate integral pilots, both providing accurate centering of mating sleeves, spacer or tandem shafts. These couplings are dynamically balanced as components and will meet AGMA classifications as designated below. Sleeves and spacers are serialized for ease of identification. Class III coupling piloted sleeves are stocked with undrilled flanges.
Because of the increased speed rating of the Class III Coupling, the rated angular misalignment is limited to ±¾°.
The Class III Coupling is available in the following series:
F, FL, FE, FS, FS Tandem, FPH.
Note: Class depends on length and size of coupling.
Class I Couplings
