Abstract

An innovative technology for the realization of key elements of a microfabricated reduction unit is presented. In view of integrating the functions of gear, pinion and axle into one element, multilevel metal electroplating in a negative dry film resist mould (Riston) is used. Easier processing, inherent planarization for multilevel 3-D structures, vertical sidewalls and high thicknesses (20-50 mu m/level) are shown to be the main key features of dry films. To demonstrate the process feasibility, a gear and pinion set with upper and lower axle posts has been realized with four levels of nickel.

Tire

A tire (North American English) or tyre (Commonwealth English except Canada) is a ring-shaped component that surrounds a wheel's rim to transfer a vehicle's load from the axle through the wheel to the ground and to provide traction on the surface over which the wheel travels. Most tires, such as those for automobiles and bicycles, are pneumatically inflated structures, which also provide a flexible cushion that absorbs shock as the tire rolls over rough features on the surface.

Rolling resistance

Rolling resistance, sometimes called rolling friction or rolling drag, is the force resisting the motion when a body (such as a ball, tire, or wheel) rolls on a surface. It is mainly caused by non-elastic effects; that is, not all the energy needed for deformation (or movement) of the wheel, roadbed, etc., is recovered when the pressure is removed. Two forms of this are hysteresis losses (see below), and permanent (plastic) deformation of the object or the surface (e.g. soil).

Aseptic processing

Aseptic processing is a processing technique wherein commercially thermally sterilized liquid products (typically food or pharmaceutical) are packaged into previously sterilized containers under sterile conditions to produce shelf-stable products that do not need refrigeration. Aseptic processing has almost completely replaced in-container sterilization of liquid foods, including milk, fruit juices and concentrates, cream, yogurt, salad dressing, liquid egg, and ice cream mix.
