Amerigear Gear Couplings ® Standard and Modified Designs
Open the catalog to page 1Crowned Flanks Flanks of the teeth are crowned so that tooth thickness is greatest at the center of the tooth. This assures larger contact area per tooth for higher torque requirements and puts more teeth in contact for a given angle. Actual tooth loading takes place near the center of the tooth face where tooth thickness is greatest. Crowned flanks also eliminate end-oftooth loading, provide optimum load distribution, and accommodate all types of misalignment with minimum backlash, while transmitting constant velocity. This design provides good oil film characteristics for efficient...
Open the catalog to page 3Design Advantages The Flexible Coupling method of connecting rotating shafts is a vital and necessary technique. Large massive shafting, loosely mounted in sleeve bearings and merely joined together by rigidly bolted flanges, cannot provide efficient mechanical power transmission. Especially today, as machine designers and builders demand higher speeds, higher torques, and higher misalignment capacities, the need for “flexibly connecting” this equipment becomes apparent. A flexible coupling is necessary since it is practically impossible to achieve and maintain perfect alignment of coupled...
Open the catalog to page 4Design Advantages Amerigear® Amerigear Fully-Crowned Teeth (Fig. 1) Crowned Flanks, Crowned Tips, Crowned Chamfers — recognized as the ultimate in gear tooth design and the secret of superior mechanical power transmission! Increased tooth contact area improves the load-carrying capacity of the teeth regardless of operating conditions and provides “balland-socket” piloting action at all misalignments. As a result, connected equipment is able to operate at higher torques, speeds, and misalignments with resultant longer life. Rigid, strong, “floating” sleeve (Fig. 2) A floating sleeve,...
Open the catalog to page 5Ordering Information 1. Obtain Shaft Sizes Compare shaft sizes of driving and driven equipment with listed maximum bores of desired Series or Type coupling to determine “tentative” coupling size. NOTE: Maximum bores are listed on pages 8 and 9 for F Type couplings and on page 29 for C Type couplings. Both Series F and Series C, Size 202 have capacities of 50 HP/100 RPM. Note: Series F and Series C, Size 202 will accommodate a 23/4” shaft with standard square key. In this example, the rating of 50 HP/100 RPM provides a large margin of safety. Recommended Service Factors (S.F.) In order to...

Open the catalog to page 8Series F Flexible Couplings Sizes 208-230 Flanged Sleeve — Double-Engagement Type Application: Meets requirements of severe service conditions and larger shaft sizes up to 46” diameter. Compensates for all three types of misalignment. Description: Heavy-duty Amerigear Series F Flexible Coupling (Sizes 208230) contains the same basic design features as Series F (Sizes 200-207), described on page 8 . . . however, misalignment capacity is ± 3/4°. Major components are fully-machined from medium carbon steel. DIA. Optional Bolt Thru Seal Retainer Lube Plug 2 @ 180˚ Each Flange *If higher torque...
Open the catalog to page 9Series FS Flexible Couplings Sizes 200-207 Flanged Sleeve — Single-Engagement Type Application: Used primarily in tandem pairs, connected by intermediate floating shaft or as individual unit in conjunction with a driver or driven shaft having a self-aligning support bearing. When used singly, compensates for angular misalignment only. Description: Amerigear Series FS Flexible Coupling consists of one standard flexible half coupling and one rigid half. The bolted center flanges facilitate installation and alignment. If used in tandem assemblies, see page 24 for shaft sizes and page 37 for...
