MAV Locking Assemblies
MAV Locking Assemblies
Keyway and splined locking systems show important disadvantages, in particular under overload and frequent torque reversals. The notch of keyway seat is a stress concentrator which reduces fatigue strength. Keyways and splines are eliminated by forced fit systems, where high radial pressures are generated. MAV SpA of Italy has been in this competitive field for the past 30 years and is a major player in the US, Australian and European market. Manufactures high quality shaft-hub connections encompassing a range from 6 to 600mm (as a standard).
Also known as Clamping units and used as Keyless Bushes to mount products onto shafts, without keys and keyways. Has built up unique expertise in designing and manufacturing clamping units to conform to individual requirements and various types of coatings (for critical environment applications).
A very wide range of models (ID/OD retained the same, for standardization, in most models) to suit varied lengths of products being mounted, run out characteristics (self-centering and non self-centering) and torque being transmitted.
Strengths:
Working in collaboration with customers, MAV has developed various solutions to applications, using FEM analysis, which allows to verify the strength and safety features of their product range.
A modern machine shop with robotically controlled machines enables MAV to provide consistent dimensionally stable products. MAV Shrink Discs or external locking devices, which provide a rigid, zero-backlash frictional connection between hollow shafts (hub) and shafts. These elements offer extremely concentric and well balanced connections, ideal for high speed applications. Presented in 3 options – Heavy, medium and light, depending upon torque transmissions. Also available in SPLIT version. For oxidising/corrosive operating conditions, Stainless Steel as well as surface coated units are available with zinc/ nickel plating and phosphate treatment.
We also offer: ETP Keyless Bushes, ROTAR Universal Joints, Trasmil Cardan Shafts, StS Metal bellow/Magnetic Couplings, Samiflex Elastic Couplings, Agricultural PTO Shafts/Gear Boxes Hutchinson Poly V-Belts & Ru-steel Flexible couplings.
