GEAR BLOCK ASSEMBLY

A gear or cogwheel is a rotating machine part having cut teeth or, in the case of a cogwheel, inserted teeth (called cogs), which mesh with another toothed part to transmit torque. Geared devices can change the speed, torque, and direction of a power source. Gears almost always produce a change in torque, creating a mechanical advantage, through their gear ratio, and thus may be considered a simple machine. The teeth on the two meshing gears all have the same shape. Two or more meshing gears, working in a sequence, are called a gear train or a transmission. A gear can mesh with a linear toothed part, called a rack, producing translation instead of rotation.

Parts of a lock assembly include a cylinder or lock body, where a key is inserted. When locked, the cylinder engages a series of spring-loaded pins that keep the cylinder from turning. When a key is inserted, the uneven edge pushes the pins upward to fit the key’s height in that location within the lock body. Essentially, it recognizes the correct key when the pins move into their proper places. This “opens” the cylinder, allowing the bolt to move, and you to open the lock. The lock engages a piece of metal or plastic that extends from the door into the receiver and holds it closed. In addition, a lock assembly may include mounting components, brackets, washers and bolts.
