What type of shaft coupling is used when two intersecting axes are neither collinear nor parallel______________________?
Show answer Hide answer
Answer: B. universal coupling
Explanation
A universal coupling is specifically designed to connect two intersecting shafts whose axes are neither collinear nor parallel. This mechanical joint uses yokes and a central cross to transmit rotational torque at an angle. It accommodates angular misalignment between the driving and driven shafts during power transmission. Universal joints experience fluctuating output velocities when operating at an angle, requiring paired arrangements. Needle roller bearings are typically used in modern universal joints to minimize friction at the cross pins. Drive shafts in rear wheel drive vehicles rely heavily on universal joints to handle suspension movement.
Automotive powertrains use universal joints to transmit power from transmissions to sloping rear axles. Industrial machinery utilizes universal joints in drive lines that require flexibility and angular misalignment capacity. Agricultural power takeoff shafts employ universal joints to drive implements attached to tractors. Flexible couplings accommodate minor parallel or angular misalignment but are not designed for intersecting axes. Chain couplings use sprockets and roller chains for parallel shafts rather than intersecting angle power delivery. Oldham couplings are specifically engineered to connect parallel shafts with lateral misalignment rather than intersecting axes.
