The Significance of Helical Gears and Motors to the Power Transmission Market

February 27, 2017

Helical gears are heat treated, broadened, and angled so that they can efficiently process massive loads. Power losses drop when they're properly incorporated within a gearing package. That's a brief description of an entirely vital mechanical component. Let's dig deeper. Let's see just how significant the helical geometry becomes when it works with a motor to create a dynamic but economical power transmission solution.

The Low-Loss Power Chain

Case hardened helical gears work in concert to generate an absolute meshing effect, a near perfect model of functional energy dissemination. Pages full of engineering mathematics would explain this effect in detail, but we have no wish to dazzle our audience with exotic equations. Let's just say the loading effect is equally distributed throughout the slanting teeth so that it transmits unequivocally, without generating mechanical losses. Otherwise, those losses would accumulate as the transmitting power hopped from one gear to the next.

Designed for Motorized Augmentation

The design of a top-notch gearing system is based on many factors. At the end of the day, all produced power should propagate without engendering an accompanying loss factor. Meanwhile, back in the gearing assembly, ratio altering assemblies and a motor add sidereal impact to the helical gearing package. The design is obviously gaining in complexity. Energy losses are now likely because the geometry envelope is muddying the mathematical model. In short, the power transmission market might be forced to adapt to the produced losses, that is, of course, unless the design accounts for their swelling presence.

Empowering the Power Transmission Market

Typically, the motor in this gearing configuration acts as a torque regulator. The speed and radial velocity generated by the prime mover are enhanced by adding windings and magnetic poles to the motor innards. Horsepower is, therefore, regulated. A graphical representation of the motor's output characteristics would illustrate this statement, with the line taking on a flattened profile that defeats any transient energy spikes. Then, when applied to the helical gearing assembly, the industrious motor effectively magnifies gearbox torque. In effect, the helical meshing effect is carrying out the bulk of the work, but the torque produced by the motor supplements this action while dismissing any possible loss factor.

The transient effects covered here are produced by the originating energy source and the various output stages. They live in manufacturing machinery and pumping equipment, high-volume production lines and other high-torque applications. Fortunately, although there's no luck involved, helical gears and motors function together to eliminate these transient effects and deliver resolute power.
