Half Gear couplings

Series 100 Half Gear Coupling HG-XXX
The standard Series 100 Half Gear Coupling consists of a flexible and rigid half. The flexible half is a standard Series 100 half coupling consisting of an outer sleeve and an inner hub and the rigid half consists a flanged hub.

Half Geared coupling are most commonly used in floating shaft applications or on line shafting to accommodate axial expansion, these gear couplings pilot shafts and also compensate for up to 1 ½ angular misalignment. Also the rigid hubs can accommodate larger shaft diameters than the gear hubs.

Series 1100 Full Gear Spacer Coupling FGSA-XXX
Many centrifugal pumps and compressors are mounted in relation to their drive and driven units so as to provide sufficient space between shaft end to facilitate maintenance, such applications require spacer type couplings where the spacer can be removed for maintenance without disturbing the equipment thereby retaining the original shaft alignments. The Series 1100 Full Gear Spacer Coupling consists of two flexible half couplings of Series 1100 connected by a flanged tubular spacer which are available in various lengths. Step type ( Hybrid ) Spacer couplings are also available to connect couplings of different sizes at the two ends.

Spacer type couplings are available in ail sizes of the standard series and also can be custom built as per customer specifications.

Series 100 Half Gear Floating Shaft Coupling HGFS-XXX
When driving and driven shaft are widely separated,an un supported or floating shaft is used to span the gap. The two couplings require at each end of that shaft consists of one half of a standard coupling bolted to a Rigid Hub,each unit called a Flex-Rigid Coupling. Usually, the rigid hubs are mounted on the driving and driven shafts so that the flex halves on the floating shaft may be replaced without disturbing the connection equipment. The offset misalignment capacity of the floating shaft assembly increases as the distance between the gear meshes increases. Maximum design offset capacity may be calculated by multiplying the CL - CL of the teeth by the factor. 0.26 to obtain offset mis-alignment in inches. Any application requiring offset misalignment in excess of 0.013 times ( CL - CL ) of teeth should be referred to Flex - Tran for review.
