The Benefits of Ring Gear

About 1/3 of motor-driven motion systems employ gearing, yet ring gears are beneficial for applications with a limited size and those operating at less than 1,000 rpm. The benefits of using a gearhead in conjunction with the servomotor are numerous. Here are the benefits of ring gear.

High power density

The term “power density” refers to the amount of energy (time amount of energy transferred) per volume. For planetary gears, loads are shared between many planets rather than single gears like another gearing. 

The greater the number of planets, the more sharing of load, and thus the greater power density. This is why the ring gear has an extremely high power density compared to conventional gearboxes parallel to the axis. 

The reduction is due to the high quantity of planet gears’ multiple kinematic combinations and the torsional reaction. Coaxial shafting and pure torsional reactions are the primary factors determining planetary gears’ power density.

Compact Size

These ring gears are smaller because of the high power density and the coaxial shaft layout. When using the ring gear, the driving and driven members are concentric, which means that the driving and driving equipment can be connected in the same direction, which will save space. 

Using multiple planet gears can help attain high gear ratios in tiny spaces. Ring gears can be more suited for applications that require rapid speed reduction in small spaces.

Light Weight

The high power density and small size result in a lightweight, as a result of which, for the identical gear ratio or torque, the ring gear is lighter than other conventional (parallel shaft) gearboxes.

Longer life

The mode of motion in the ring gear differs from conventional gearboxes that are parallel. 

Traditional gears depend on a few connections between gears to transfer the driving force. In this scenario, the entire load is concentrated around a handful of contacts, so the gears wear out quickly and may even crack. 

The planetary gears, however, have many gear-contacting surfaces with greater surface area, which can spread the load evenly across the central axis. 

Multiple gear surfaces can share the load, including any impact load that is instantaneous equally, making them less susceptible to damage caused by higher torques. When applying torque, an equal distribution of torque is created among the sun’s pinion and the planets. 

In the absence of bearings on the pinion, the pinion becomes free to flounder, and the load applied immediately centers itself around the pitch circle, resulting in an equal share of the load among the planets. 

To ensure that the load is evenly distributed to the annulus or ring gear, this planet-carrier is rigid in structure and design, thereby decreasing the deflection of elastic forces across the pins of planet ring gear bearing. 

The spur gear teeth exert no Axial force on the gear components. Thus, a gear ring will have a longer lifespan of gears than conventional gearboxes for the same load.
