Types G52, GV52<br />
The Type G52 single engagement design is used with floating<br />
shafts or three bearing drive trains. It has one flex half and one<br />
rigid half and only accepts angular misalignment. (See Pages 21<br />
and 43.)<br />
The GV52 vertical single engagement gear coupling is a<br />
standard horizontal single engagement gear coupling modified<br />
to accommodate the sleeve centering assembly. It recommended<br />
for inclinations over 10°. Downward thrust capacity for Sizes<br />
1010 thru 1030GV52 is 10,000 lbs.; Sizes 1035 thru<br />
1070GV52 is 30,000 lbs. and Sizes 1080GV52 and larger is<br />
87,000 lbs. (See Pages 25 & 46.)<br />
Floating shaft assemblies are used when distance between<br />
equipment is too great for spacer couplings. A standard floating<br />
shaft assembly consists of two standard single engagement<br />
couplings, two gap discs and a connecting shaft. A floating shaft can<br />
eliminate the need for additional bearing supports along spanning<br />
shafts because the shaft is supported by connected equipment<br />
through the single engagement couplings. (See Pages 22, 23, and<br />
44.) When used with a vertical floating shaft on inclinations over<br />
10°, the Type GV52 coupling is used as the lower coupling to<br />
support the shaft. (See Pages 25 and 46.)<br />
Flex Hubs on Floating Shaft (RFFR) — Assembly of the flex hubs<br />
on the floating shaft allows for easier replacement and allows the<br />
rigid hubs with greater bore capacity to be used on the connected<br />
equipment shafts. This frequently means a smaller coupling size<br />
can be utilized.<br />
Rigid Hubs on Floating Shaft (FRRF) — When the rigid hubs are<br />
on the floating shaft, shorter shaft spans can be accommodated,<br />
since no cover drawback is required.<br />
Types G52, GV52<br />
Double or single engagement brakewheel and disc brake<br />
couplings are used for applications, such as cranes, hoists and<br />
conveyors. Brakewheel and disc brake couplings accommodate<br />
misalignment between connected equipment and eliminate the<br />
need for double shaft extensions on motors and gear drives for<br />
applications requiring brakes. (See Pages 26 and 27.)<br />
Types G62 & 66<br />
Type G63<br />
Double and single engagement Slide couplings are used for<br />
applications requiring axial movement to accommodate thermal<br />
shaft expansion or adjustment. (See Pages 28, 29, and 47.)<br />
