Gear Overview JW JW Vari-Crown® Tooth Form CJ CJ With straight hub teeth, there is a high concentration of load under misaligned conditions. As misalignment increases, more of the load is carried by the ends of the teeth, resulting in premature breakdown and coupling failure. JIS JIS Straight SF SF G HP HP G Some manufacturers use a conventionally crowned hub tooth known by various trade names. Regardless of the nomenclature, however, the contour of the tooth is a segment of an arc. Under all operating conditions, equal or similar contact areas between the hub teeth and the sleeve teeth...

Gear JIS CJ The following is a list of the information necessary to assist in making a coupling selection. Not all of these items will come into play in all selection processes. These items include, but are not limited to: Application related: • Application details • Type of motor and driven equipment • Motor horsepower or KW • Operating/coupling speed • Shaft sizes and separation • Space and size constraints • Environment (temperature, chemicals, etc) • Balance requirements • Special modifications Step 4: ompare the required total torque value with the nominal torque capacity C listed in...
