Speed reducer Gearbox & Mecanum wheel

1) Speed reducer Gearbox Gearboxes and speed reducers are mechanical speed reduction equipment used in automation control [login to view URL] also reduce the input power source speed to achieve desired output speeds. Principles :- A worm gear is a type of interlocking gear composed of a worm shaft and worm wheel. The worm is shaped like a screw and the worm wheel is a type of gear machined to have a tooth profile with the same configuration. The operation of a worm gear is similar with that of a bolt and nut. The principle is the same as a nut that has been fixed so that it cannot rotate and therefore progresses in the axial direction when the bolt is turned. The design of a worm gear is thought of through the relationship between the rack and spur gear on the middle plane of the worm wheel. Operation In a single thread worm, when the worm shaft rotates one time, the worm wheel progresses by one tooth (rotates). In a double thread worm, the wheel progresses by two teeth. 2) Mecanum wheel The Mecanum wheel is an omnidirectional wheel design for a land-based vehicle to move in any direction. Each Mecanum wheel is an independent non-steering drive wheel with its own powertrain, and when spinning generates a propelling force perpendicular to the roller axle, which can be vectored into a longitudinal and a transverse component in relation to the [login to view URL] Mecanum wheel is based on a tireless wheel, with a series of rubberized external rollers obliquely attached to the whole circumference of its rim. These rollers typically each have an axis of rotation at 45° to the wheel plane and at 45° to the axle line.
