Key Point 1 of Mechanical Element Design

Introduction to "friction fasteners" that generate strong clamping force (frictional force) to secure the shaft and hub.

This time, we will introduce friction fasteners that connect shafts and hubs, marketed under names such as Power Lock and Mecha Lock by manufacturers, without the use of keys. The principle of fastening involves the inner and outer rings being in contact with each other at a taper, and by tightening the lock bolt, a strong clamping force (frictional force) is generated, securing the shaft and hub together. There are various types available to suit different applications, so caution is necessary when using them. 【Points】 ■ Presence or absence of centering function ■ Whether there is movement of the hub in the axial direction when tightening the lock bolt ■ Usable even if the shaft has a keyway ■ Do not use molybdenum-containing grease or oil with extreme pressure additives ■ Tightening of the lock bolt should be done using a torque wrench, adhering to the specified torque *For more details, please refer to the PDF document or feel free to contact us.
