Shrink Disc

NMTG India is a leading manufacturer of Shrink Disc, offering high-quality products to clients worldwide, including

Shrink disc consists of either one or two thrust rings with tapered bores and a mating tapered inner ring. By tightening the screws the thrust rings are close together and compress the inner ring which generates the pressure on the hub and endeavors to clamp with the shaft and transmit the torque.

Shrink Disc

Two-Part Shrink Disc — The stepped taper outer ring is pulled onto the stepped taper inner ring by tightening the clamping screws. A radial clamping force is generated by the taper surfaces, The radial clamping force presses the hollow shaft onto the shaft and creates a frictional bonded connection at the contact surfaces between the shaft and the hollow shaft. Thereby, torque / axial force can be transmitted between the shaft and the hollow shaft.

Three-Part Shrink Disc — The front nut and rear nut are pulled together over the inner ring by tightening the clamping screws. A radial clamping force is generated by the taper surfaces.

The radial clamping force presses the hollow shaft onto the shaft and creates a frictional connection at the contact surfaces between the shaft and the hollow shaft. Thereby, torque / axial force can be transmitted between the shaft and the hollow shaft.

Overrunning clutch

Image
  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

Shaft Couplings

Image
Enhance your machinery’s performance with NMTG’s keyless coupling solutions, shaft couplings, and torque nuts for… The main function of the rigid coupling is the safe and backlash-free connection of two shafts by means of friction. This connection is mainly used to transmit torque. The coupling is simply pushed onto the shaft and fastened so it is frictionally engaged by tightening the screws in the shrink disc/locking assembly. They transfer torque and bending moments as well as axial and radial forces. Advantages Strong connection with high torque capacity Easy assembly and disassembly Backlash-free shaft hub connection High level of true running accuracy No heating necessary No hydraulic necessary Pursue the same diameter — but an adaptation to different diameters is also possible Shaft Couplings NMTG is a leading manufacturer in specialized markets for Mechanical Power Transmission Products. Our main products are  Keyless Transmission Elements, Freewheel One-way Clutches, Holdb...
