HA Series Locking Assemblies
A locking assembly is typically designed for high torque, bending moments, or axial loads. This allows a shaft-hub connection to transmit torques and axial forces reliably. In addition, locking assemblies eliminate wear and backlash problems and simplify installation and dismantling of host parts.
HA Series Locking Assemblies
A locking assembly is designed to transmit forces evenly over 360 degrees of contact. This is achieved by distributing torque-transmission stresses along the conical surface of the locking assembly. It also provides good interchangeability. In addition, it reduces work and component spending. It is an ideal replacement for keyways and bored and keyed connections. It eliminates the need for cooling, heating, and pressurized equipment. It is also ideal for rotary table devices, pumps, and brake disc mountings.
A locking assembly may consist of one or two conical pressure rings. These rings are pulled onto the conical surfaces of the clamping sleeve by tightening clamping screws.
A locking assembly can be installed in any position. It has an indent 60, a corresponding capture portion 48, and a pin 70. These components create a frictional shaft-hub connection. This connection reliably transmits axial, radial, and bending moments.
Principle of HA Series Locking Assembly
| HA Series locking assembly is a kind of keyless coupling device. The principle and use of this locking assembly are to generate a huge holding force between the inner ring and the shaft and between the outer ring and the hub through the action of high-strength tension bolts so as to realize the keyless connection between the parts and the shaft. When under load, torque, axial force, or the combined load of the two is transmitted by the joint pressure of the locking assembly, the machine part, and the shaft and the accompanying frictional force. |  |
