Elastomers In Compression
We gives four types of elastomer models to allow for extra versatility in addressing specific application demands. A single piece types are utilized in the “L” and “AL” versions (referred to as spiders) and a number of portion “load cushions” are utilized in the “C” and “H” model couplings. The load cushions are in sets of 6 to 14 pieces based upon coupling size.
Reliable Center Spider
The solid center design and style is usually applied layout when shafts from the driver and driven gear could be kept separate by a normal gap
Open Center Spider
The open center design allows for the shafts with the driver and driven to be positioned inside of a short distance
Open center spiders supply shaft positioning flexibility but have a reduced RPM capacity
Cushions
Made use of solely for the C and H Kind couplings
Load cushions are held in spot radially by a steel collar that is attached to one of several hubs
Snap Wrap Versatile Spider
Design permits for simple elimination in the spider without the need of moving the hubs
Will allow for near shaft separation all the way up to the hubs maximum bore
Maximum RPM is one,750 RPM with the retaining ring, but if utilized with all the LC Variety (with collar) the normal RPM rating in the coupling applies
Type is obtainable in NBR and Urethane only, and in constrained sizes
Spider Products
SOX (NBR) Rubber
The regular materials that may be remarkably versatile material that’s oil resistant
Resembles pure rubber in resilience and elasticity, and operates correctly in temperature ranges of -40° to 212° F (-40° to 100° C)
Urethane
Has 1.five instances greater torque capability than NBR
Very good resistance to oil and chemical compounds
Materials delivers significantly less dampening effect and operates at a temperature selection of -30° to 160° F
Hytrel
Flexible elastomer designed for higher torque and higher temperature operations
Operates in temperatures of -60° to 250° F (-51° to 121° C)
Bronze
Rigid, porous, oil-impregnated metal insert solely for lower velocity (max 250 RPM) applications requiring large torque capabilities
Not affected by water, oil, dirt, or excessive temperatures – operates in temperatures of -40° to 450° F (-40° to 232° C)
