The invention relates to a mechanical catapult which comprises a cylindrical body, a flexible disk (1) that is arranged inside the cylindrical body, more than three strip elastic bodies (2) and more than three fixed pulleys (3); all the fixed pulleys (3) are distributed evenly at the ...
Mechanical power transmission serves the function of transferring rotational power from a driver to an output component. This process enables control over the applied power's quantity, speed, and torque. It offers key advantages such as flexibility and simplicity, and frequently surpasses electrical mea...
Versatile single and multiple ply belt constructions are available. Design advantages include: outstanding flex-life, operational smoothness, and precise tracking. MEI's semi-elastic types eliminate idler and tensioning pulleys. Typical power transmission and conveying applications include sensitive recording ...
