ABSTRACT:
An improved planetary gear box for a heavy duty truck jack which includes a planetary gear box that provides high torque and in-line input and output shafts and a high gear ratio and a compact package which does not require many precision machine parts. The invention uses parts formed by stamping rather than machining and uses a floating ring gear which can move relative to the housing, thus, allowing a stamped ring gear to be utilized. Floating planetary gears are used by providing slotted carriers whic allow the planet gears to float which eliminates concentric problems with the planet gears and the carrier assembly. The invention allows the use of a stamped housing and the rear carrier of the planet gears is staked to the drive pilot of the jack screw. The invention results in an improved and less expensive jack than utilized in the prior art.
