Elastomers In Compression
We delivers 4 kinds of elastomer models to allow for more flexibility in addressing certain application necessities. One particular piece types are used in the “L” and “AL” models (referred to as spiders) and numerous component “load cushions” are used in the “C” and “H” model couplings. The load cushions are in sets of six to 14 pieces depending on coupling dimension.
Solid Center Spider
The reliable center design is generally utilized design when shafts on the driver and driven equipment is often kept separate by a normal gap
Open Center Spider
The open center design makes it possible for for your shafts from the driver and driven to become positioned inside of a brief distance
Open center spiders supply shaft positioning flexibility but possess a reduce RPM capability
Cushions
Used exclusively for that C and H Kind couplings
Load cushions are held in place radially by a steel collar which is connected to one of many hubs
Snap Wrap Flexible Spider
Design makes it possible for for straightforward elimination in the spider devoid of moving the hubs
Will allow for shut shaft separation all the way up to the hubs optimum bore
Greatest RPM is one,750 RPM with the retaining ring, but if used with all the LC Type (with collar) the typical RPM rating with the coupling applies
Style is available in NBR and Urethane only, and in constrained sizes
Spider Components
SOX (NBR) Rubber
The common materials that is certainly hugely flexible material which is oil resistant
Resembles purely natural rubber in resilience and elasticity, and operates successfully in temperature ranges of -40° to 212° F (-40° to 100° C)
Urethane
Has 1.five occasions higher torque capacity than NBR
Superior resistance to oil and chemicals
Material delivers much less dampening impact and operates at a temperature choice of -30° to 160° F
Hytrel
Flexible elastomer made for substantial torque and substantial temperature operations
Operates in temperatures of -60° to 250° F (-51° to 121° C)
Bronze
Rigid, porous, oil-impregnated metal insert exclusively for lower pace (max 250 RPM) applications requiring high torque abilities
Not affected by water, oil, dirt, or severe temperatures – operates in temperatures of -40° to 450° F (-40° to 232° C)
