High quality NMTG Locking Assemblies made of stainless steel are the preferred choice for all drive applications that place highest demands on the corrosion resistance of the components being used.
The high quality NMTG locking assembly made of stainless steel is the preferred choice for all drive applications that place the highest demands on the corrosion resistance of the components used. (i.e: Pump Manufacturing, food and beverage industry and in medical technology). In general, stainless products are used wherever increased risk of corrosion and purity are important criteria. Stainless steel in particular offers a variety of applications in the field of stainless constructions.
Our stainless steel locking assembly transmits torque as well as radial and axial forces completely backlash free and is also completely free from wear and maintenance. They are available as special solutions to suit users and in a wide variety of installed, readily available standard sizes and types.
Easy to detach, compact design
For individual clamping connections compact design, most cost-effective
Centres the hub to the shaft, radial flate height, for thin-walled hubs
Centres the hub to the shaft for small shaft diameters
Two Part Model with Slotted Single taper design as well as with Flange
NMTG Keyless Locking Assemblies works based on wedge friction theory. By tightening screws, clamp force is generated and due to taper geometry, the clamp force transmits force to other member in radial direction which induced contact pressure to the shaft & Hub. Clamping system connect two or more parts to shaft and hub which allow motion to be transmitted and to withstand an axial thrust. Due to Interference between two bonded parts at shaft and hub the torque can be transmitted from shaft to the hub through locking assembly.
Locking Assemblies develop pressure between shaft and the hub, which transmits highest torques free from backlash. Keyless transmission elements which have varied and versatile applications on almost all engineering fields. The elements have great absorbing capacity of kinetic energy by elastic radial deformation of tapered rings. The method is also very simple. By expansion of the outer ring & shrinkage of inner rings, frictional shaft & hub connections are established,
Thus gears, chain sprockets, pulley, drum, cam discs, flywheel can to be attached preciously. The supplied locking devices are ready for installation.
Though apparently seems simple but preparing keyway is one of the difficult machining operations:
The cumulative effect of the all above (operational) errors, is really calls for an alternative system-keyless Transmission.
NMTG Keyless Transmission Elements entirely eliminates drawbacks of key transmission and conventional shrink connections and also involved calculations, extremely close machining tolerances - creating problems while fitting & removing parts and during repair work - adjustment, exchanging, etc. It efficiently replaces, key & polygon connections, splined shafts, etc.
on the shaft-hub connections compared with traditional systems
Keyless Locking Assemblies are most suitable for securing all types of bosses and hubs on shafts and axles:
In this way, they can safeguard valuable machine components against damage. However the slip causes fretting of the contact surfaces, so elements should not be used as slip clutch.
