The latest designed ALS Couplings from Miki Pulley are available in three different types for more precisely handling parallel, angular or axial misalignment applications.
Stainless steel ASK Couplings from Miki Pulley feature a unique “sliced” body structure making them an effective low-cost corrosion resistant solution that can accommodate many types of misalignments. The stainless-steel design makes them ideal for use in food and chemical applications.
A flagship coupling in the Huco range, the Oldham solves the problem of side forces due to misalignment. Misalignment couplings that bend or flex do cause some side loading on bearings and shafts as the coupling tries to spring back. Of course, over prolonged use this can result in rapid deterioration of bearings, extra load on the motor, and eventual coupling fatigue.
Involute splines are commonly used in gearboxes to connect gears and shafts, especially when high torque is transmitted through the coupling. The load is shared among multiple teeth around the coupling circumference, resulting in higher load capacity than a conventional single key. However, the total load is not equally shared among all spline teeth, mainly because of
pitch deviations resulting from the manufacturing process. The load distribution along the spline engagement length is also nonuniform
because of tooth misalignments and shaft torsional effects. This paper presents an investigation of the influence of spur gear loads on the load distribution of spline teeth.
