Final Drive Housing

The housing on a final drive is the container that will enclose the final drive components, keep them in a lubricated environment, and connect to the machine. Because of the immense forces happening inside the final drive, the housing must be constructed to stand up to both internal and external forces. In heavy construction equipment, the final drive housing can be incredibly large and heavy. Overhead cranes, forklifts, and other equipment are often needed to work on a final drive.

Planetary Gears

In final drives with planetary gears, there are often two sets of planetary gears — an inner planetary and an outer planetary — each composed of a set of three planet gears and held together by a carrier.

Sun Gear

At the center of planet gears is the sun gear. The sun gear is the component bringing force into the final drive to be transformed into high-torque output.

The Ring Gear

The ring gear sits around the planet gears. The planet gears, taking power from the sun gear, turn inside the ring gear as they transform the power into increased torque.

Ball Bearings

Ball bearings are a common component to machines of all types, purposes, and designs. Bearings are designed to allow specific movement while greatly reducing friction. In a ball bearing, balls are contained inside of bearing races. To ensure proper functionality bearings must be designed and crafted to meet exact specifications and standards. Bearings in a final drive must be well-oiled at all times to reduce fiction.

O-Rings and Seals

O-rings and seals are another common component in any mechanical system. In a final drive, the O-rings and seals are designed to keep all lubricant inside of the housing and to prevent outside elements from entering the housing. Both the loss of lubricant and the introduction of foreign matter into a final drive will lead to fast and detrimental degradation of the internal components
