Automation Experts Debate Curved Jaw Coupling Spider Hardness Levels Gs Bonna Flex

Spiders are key to jaw coupling performance one of the most widely applied types of flexible couplings is an elastomeric design known as the jaw coupling We manufacture multiple styles of jaw couplings This design is characterised by two hubs, each having two or more thick, stubby protrusions around their perimeters, called jaws, pointing toward the opposing hub.

First came the curved jaw design, so named because jaws and spider legs have both radial and axial curvature (crowning) Why choose our star jaw couplings This hub and spider configuration offers more torsional softness at lower torque levels than the standard jaw coupling and extends angular misalignment capability up to 1.5 degrees.

By design, jaw couplings are a relatively balanced coupler capable of high torque transmittal and high speeds with little or no backlash

The curved jaw coupling includes two metal hubs and an elastomeric spider element The spiders are available in different hardness durometers, each easily identified by its color. Common coupling spider types by design (shape) while the material is key, the shape of the spider must match the design of your coupling hubs These are the spiders used in most standard jaw.

Jaw coupling computer drawing of a curved jaw coupling in mechanical engineering, a jaw coupling is a type of general purpose power transmission coupling that also can be used in motion control (servo) applications. Just as coupling designs differ to satisfy different application criteria, so do the spiders in jaw couplings The spider determines the coupling's torque rating It also affects the coupling.

Curved jaw coupling are available in 5 hubs materials (sintered iron, steel, aluminum, cast iron, or nodular iron materials), and 4 spider materials (80a, 92a, 95/98a, & 64d shore)

Jaw couplings consist of two metallic hubs and an elastomeric spider The interlocking jaws of the hubs engage with the spider, transmitting torque while providing excellent vibration damping and shock absorption This makes them ideal for various. The jaw coupling consists of two hubs with curved jaws that interlock with a spider placed in between

When torque is applied to one of the hubs, it causes the jaws (on that hub) to grip the spider. Polyurethane (pu) is a special material that offers the resilience of rubber combined with the toughness and durableness It allows people to substitute rubber, plastic and metal with pu Polyurethane can reduce factory maintenance and oem product cost

Polyurethane has better abrasion and tear resistance than rubbers, and offering higher load bearing capacity

Selecting the right type of spider is just as important as selecting the right type and size coupling For that reason, users will benefit from a fuller understanding of the different spider constructions and materials available, when specifying new or maintaining existing couplings Curved jaw couplings handle angular shaft misalignment and small amounts of parallel misalignment Use curved jaw couplings in applications involving minimal to moderate shaft misalignment

Cardan jaw couplings have an extended length that doubles the angular misalignment capability and exponentially increases the radial misalignment capability. For mounting the hubs of the elastomer coupling are simply pushed on the shafts and axially fastened via setscrews. The curved jaw coupling consists of two standard hubs and one elastomeric spider Elastomeric spiders are offered in four different shore hardnesses
