The size parameters of gear wheels

The main parameter of the gears that you need to pay attention when they selecting for Your project is the number of teeth located on the outer circumference of the wheel. For gear wheels with large teeth are easy to manually calculate their ratio, given the small number of teeth. And in that case, if the gearbox of a large number of small teeth, selection of project, this can be problematic, and then it is best to rely on the documentation provided from the manufacturer. Another parameter that determines the geometry of the gears and the module, i.e. the size of one tooth is determined on the basis of several funds of the same name side surfaces of the teeth from each other. The bigger the block, the more the teeth of the wheel. Picking up the toothed wheel should take into account their diameter connector and an outer diameter. Pitch diameter is defined by the line passing through the centers of the distance between the teeth on the circumference of the toothed wheel, and the outer diameter is determined through a line connecting the tops of the teeth opposite each other on the circumference of the base gear. Respectively, should be selected and material - choice we have gears, plastic plastic, and aluminum.

Performance parameters of gear wheels

The effectiveness of gear is determined by its performance parameters, i.e. torque, speed and power. Torque shows the force applied on the shoulder of a given length - for gears, the torque depends on the diameter of the wheels between which it is passed. The speed of the block of gear wheels determines the number of turns performed for a specific period of time for around of the system output. When the wheel of larger diameter drives the wheel of smaller diameter, for one revolution of the large wheel, the smaller wheel will make more revolutions in the same period of time - this decision is the gearbox increases the rpm. A small wheel large driving wheel, is a system to decrease the speed of rotation. The ratio of the sizes of the two wheels, interacting with each other linearly proportional to the changes of speed and torque between them. In turn, the capacity of the gear train determines the maximum amount of energy that the system can provide within a time unit. The value of the power reducer, also significantly affects the output power of the drive system reducer, for example, on the motor shaft, the power at the gearbox output remains constant, regardless of the size of the gear wheels forming a gear.
