Application of the pulley to the washing machine

The use of technopolymers with high performances of mechanical and wear resistance for the production of the washing machine pulley, together with a new design, is the solution to reduce the component weight and to increase its recyclability.

Manuela Gioberti

The use of a highly performing plastic material, combined with an engineering approach to design, has allowed Meccanica Generale to launch on the market a new innovative pulley for washing machines, fully made of plastic, without the addition of any metallic insert and able to grant high mechanical resistance to wear and deformations, replacing the same component, certainly more expensive and heavier, already produced in aluminium. With excellent mechanical performance, of resistance to heat and chemical agents, lightness and highest recyclability. The patent of the company Meccanica Generale hits this target of improvement of performances and high quality of the pulley, as well as long service life and low environmental impact.

RETICULAR CONFORMATION
The reticular conformation of the pulley designed and produced by Meccanica Generale, fruit of several simulations at the structural-topological computer, allows exploiting the technological peculiarities of the material used for the implementation, reducing the component weight and at the same time granting a homogeneous distribution of stresses and of deformations in the use phase.

PLASTIC INSTEAD OF METAL
The choice of the plastic material for the production of the new pulley fell on a technopolymer with base of nylon reinforced by 65% with glass fibre, matching excellent moulding characteristics first and of mechanical resistance afterwards. That material is used for the production of components for industry instead of metal materials and it offers high dimensional stability, resistance to ageing due to heat and toughness also at high temperatures.

RESISTANT TO DEFORMATIONS
The advantages offered by the pulley for washing machines produced according to the patent by Meccanica Generale consist in the greater lightness with equal performances of mechanical and wear resistance in comparison with the traditional typologies of pulleys, according to the work commonly carried out by a washing machine. The reticular structure that characterizes the product improves the motion transmission performances, at the same time enhancing the resistance to deformations (for instance crushing and ovalization).
