Tanso Shaft Locking Devices are designed to connect hubs and shafts securely without the need for keys, using a mechanical interference fit. This system transmits torque or withstands axial thrust effectively. The locking mechanism utilizes screw tension, which is converted into radial pressure via an inclined plane. This pressure expands the locking device, filling the gap between the hub and the shaft. The friction bond created between the locking device and the shaft/hub ensures a zero-backlash connection that can be easily released. These devices offer significant advantages over traditional methods. They allow for quick installation and removal, saving time and effort. The contact pressures generated by the locking device can exceed those of conventional interference fits, enabling higher torque transmission or shorter hub designs. Additionally, they provide precise positioning of the hub on the shaft and facilitate angular timing. Installation and disassembly are straightforward, requiring only common tools to lock and unlock the clamping screws. A torque wrench is recommended for precise torque settings. Tanso Shaft Locking Devices deliver superior holding power compared to keyed hubs, with overload protection that prevents damage when pre-set torque limits are exceeded. However, excessive slip may cause damage, so it's important to avoid overloading. The design allows the hub to be clamped at any position along the shaft, eliminating the need for additional components like lock washers, spacers, or stop rings. This makes the system more efficient and versatile. Easy assembly and disassembly
Both actions take place by locking and unlocking the clamping screws with common tools.
The use of a torque wrench is only necessary when a more precise torque is required.
Superior holding power
The action of the clamping cones creates shaft clamping torque superior to a normal keyed hub.
Overload protection
When the pre-set torque is exceeded locking device will slip, preventing the connected elements from being broken.
Note: Locking units are not friction couplings, so excessive slip will cause damage.
Easy adjustment
Combining the locking device design of smooth cone action with superior holding power, the hub can be clamped at any position along a shaft, eliminating the need for lock washers, spacers , stop rings, etc.
