shaft coupling

shaft coupling is the safe and backless free connection that connects the drive shaft and drive shaft in order to transmit torque. The external clamping systems generate a backlash-free connection by pressing the connecting sleeve onto the shaft ends.

WORKING PRINCIPLE:-

Connect the hub solidly to shafts, using a keyless mechanical interference fit, to transmit torque or to withstand axial thrust. This mechanical interference fit is based on wedge base friction theory.

By tightening screws clamp force is generated and due to taper geometry, the clamp force transmits force to another member in a radial direction which induced contact pressure to the hub.

This pressure expands the Shaft Locking Device to eliminate the gap between the hub and the shaft. The Shaft Locking Device generates friction bonding between the Shaft Locking Device and the shaft/hub to create a zero backlash connection.

Due to Interference between two bonded parts at the shaft and hub, the torque can be transmitted from the shaft to the hub through the Shaft hub assembly.
Shaft Hub Connection is easily releasable to remove the mechanical interference fit.

Shaft Locking Devices expand to fill the gap between the shaft and hub, allowing for easy installation and removal, saving time over traditional interference fit techniques. The contact pressures created using a Shaft Locking Device are greater than traditional interference fit pressures, allowing for more torque to be transmitted or shorter hubs to be used.

The easy installation also allows the hub to be positioned more accurately on the shaft and can facilitate the angular timing of the hub.

Overrunning clutch

  Overrunning clutch WORKING PRINCIPLE An  overrunning clutch , also known as a freewheel one-way clutch, is a mechanical device used to transmit rotational motion in one direction while allowing free rotation in the opposite direction. In this type of application, the different conditions of engagement and disengagement are repeated arbitrarily, when the Overrunning Clutch inner and outer races engage each other to transmit torque, and when the Overrunning Clutch continues overrunning through the difference in rotating speed and direction between the inner and outer races. This is the same behavior as a freewheel on the rear bicycle wheel. BENEFITS Switching is possible only by ON/OFF operation of the high-speed motor. Switching operation is also possible when driving is distributed to multiple shafts from the main motor. https://nmtgindia.com/freewheel-oneway-clutch/overrunning-clutch

multi-jack bolt nuts

Premium high-tension nuts and bolts by NMTG India for secure and reliable fastening in critical applications for… Tensioner Nuts & Bolt is designed for direct replacement of Conventional Hex Nut & Bolt. No need of requirement of more space, just required to replace the hex nut. Normally in medium & heavy Industries, different bolted joints / connections are to be used which requires high Clamping Force. So, these require more effort in Tightening & Untightening. Major two difficulties in Large size Bolt: How to tighten the Bolt. How to keep it tight. Tightening a Bolt having an elastic stretch which keep the bolted assembly together. If the distance between Bolt head and nut is less, the elasticity will be insufficient. The better way to improve elasticity of a bolting system is by the use of our developed proven bolting system called Tensioner Nut Assembly. multi-jack bolt nuts Standard hex nuts used in such connections are tightened by the known tightening systems suc...
