WH10 WH Type Oldham Coupling \u2013 80\u2013100mm Bore Shock-Absorbing Sliding-Block Flexible Drive Coupling<\/h1>\n

The WH10 WH Type Oldham coupling<\/strong> is a sliding-block flexible drive coupling designed for applications transmitting 5000 N\u00b7m at up to 1500 rpm where a certain degree of shaft relative offset compensation, shock absorption, and vibration damping capability are all simultaneously required. With a 330 mm outer diameter and bore range of 80\u2013100 mm, it suits the full range of industrial shaft connections in this torque class \u2014 from compact instrument drives at the WH1 end of the series to large pump and processing equipment drives at the WH10 level. The coupling’s working temperature range of -20\u00b0C to +70\u00b0C covers standard industrial and outdoor service environments. The WH10 is the largest and highest-torque model in the WH series, rated at 5000 N\u00b7m for 80\u2013100 mm shaft connections. At 1500 rpm maximum speed, it serves large industrial motor connections where shock absorption, misalignment compensation, and vibration damping are all simultaneously required in drives operating at reduced speed.<\/p>\n

The WH Type coupling is a three-component sliding-block Oldham design: two identical metal hubs, each mounted on one shaft, and a central polymer slider block that simultaneously engages the tongue-groove features on each hub face. Torque is transmitted through the sliding contact between the polymer block tongues and the metal hub grooves. Relative radial displacement between the two shafts is absorbed by translational sliding of the block within the hub grooves during rotation. The polymer block material provides inherent shock absorption by deflecting elastically under peak torque loads, attenuating transient torque spikes before they are transmitted to the connected shaft and its bearings. This shock absorption characteristic distinguishes the WH Type from rigid Oldham couplings and makes it particularly valuable in drive applications with variable or intermittent loading.<\/p>\n

Y-type (standard length) and J-type (short hub) bore configurations are both available for the WH10, with bore length dimensions of 172\u2013212 mm (Y-type) and 132\u2013167 mm (J-type). The full WH series documentation and selection guidance is available on our product catalog page<\/a>.<\/p>\n

Hub and Slider Block Assembly<\/h2>\n

\"WH10<\/p>\n

The WH10’s intermediate slider block is the functional core of the coupling. Machined from engineering polymer to precise tongue and groove dimensions, the block simultaneously engages the drive faces on both hub ends. The tongue width and groove dimensions on the WH10 are sized to provide adequate compressive contact area for reliable 5000 N\u00b7m torque transmission while maintaining the sliding clearance needed for radial compensation movement during rotation. The tongue depth dimension C = 62 mm determines the shear plane geometry of the engagement and is a key parameter in the coupling’s shock absorption capacity.<\/p>\n

\n
\n

Shock Absorption<\/h3>\n

The polymer slider block deflects elastically under peak torque loads, attenuating drive transients and protecting both motor and driven equipment bearings from shock loading. This is the primary functional differentiator of the WH Type over rigid Oldham couplings.<\/p>\n<\/div>\n

\n

Shaft Offset Compensation<\/h3>\n

Radial shaft offset between the two connected shaft centrelines is absorbed by the sliding mechanism, preventing transmission of radial forces to motor or driven equipment bearings \u2014 reducing bearing overload and extending equipment service life.<\/p>\n<\/div>\n

\n

Vibration Damping<\/h3>\n

The polymer block’s internal damping dissipates vibrational energy transmitted through the drive shaft, reducing vibration levels in both the motor and driven equipment \u2014 beneficial in applications where vibration affects product quality or equipment fatigue life.<\/p>\n<\/div>\n

\n

Y and J Bore Options<\/h3>\n

Both standard-length Y-type and short-hub J-type bore configurations are available, accommodating applications with different axial space constraints between bearing supports.<\/p>\n<\/div>\n<\/div>\n
