Gear Boxes are familiar devices in mechanical systems. They are used to couple rotational motion among different parts of machines and provide an effective method of increasing torque at the expense of reducing the rotational speed or vice versa. Gearboxes are filled with the silicone-graphite oil used on the chains.
Gear coupling is a mechanical device for transmitting torque between two shafts that are not coaxial. It consists of a flexible joint fixed to each shaft. The two joints are connected by a third shaft, called the spindle. It consists of involute-toothed hubs which mesh with an intermediate sleeve or shaft. They allow significant amounts of angular misalignment and axial movement. Gear couplings have higher torque densities than universal joints designed to fit a given space while universal joints induce lower vibrations. The gear coupling equipment has five major components such as two hubs, two sleeves and spacer. It also has a number of bolts, nuts, lockwashers, and two or more seals. The spacer is omitted when the separation between the connected shafts is small. The hubs have a row of external teeth with involute profile; the sleeves have matching internal teeth.
Gear Driven Positioner have sturdy positioners that solve many problems met in welding automation. It is used to save time particularly when welding various types of work pieces. It is possible to select the rotational speed of the table. The table offers up to 135° of tilt. They assure maximum versatility productivity in the welding of circular parts. The pneumatic cylinder is used to move the welding torch for automatic cycle. The overlap timer and the automatic zero point researchers are necessary for automatic cycle.
