Basically, this factor implies a rotational speed difference between the two shafts. This ratio results from the difference in diameters of both gears, giving the name ‘pinion’ to the one of the smallest diameter. Gear ratio: It is basically the relation between rotational speeds of two meshed gears, where one of them exerts a force on the other.In order to face this complex process, let’s begin by properly establishing the most critical terminology regarding gears : Gears terminology This is the heart of the matter when it comes to gear calculation. In line with this, it is paramount to analyse in-depth how the gear and the flanks of the pinion’s tooth engage when designing a smooth rotational transmission (maintaining a constant angular speed ). Knowing how different types of gears work is key when opting for one or another in your industrial projects. Bevel gears which transfer motion rotationally on converging shafts.Those that operate on transmissions that have perpendicular shafts (helical gears that rely on a worm screw for torque transmission).Those that operate on parallel shafts mounted on a pinion: spur gears, helical gears, double helical gears, epicycloid gears, etc.What types of gears stand out in today’s industry? In addition, they stand out due to the great efficiency with which they deliver power, limiting energy loss as a result of a lower friction between its surfaces. In a myriad of applications, geared transmissions are in charge of transferring the right torque provided by a motor, being, in fact, the most reliable, strong and resilient transmission systems.
More specifically, we will focus on their terminology, gear formulas, and even aspects related to gear design that will help you prevent premature failures and perform an optimal gear calculation. In this article we discuss the key elements that will help you with the design of gears for your projects.
Gears are a key component in a wide range of motion control devices, as well as in mechanical and electromechanical transmissions.
