Abstract

A driving device includes a motor and a gearbox. The gearbox includes a first sun gear, first planetary gears surrounding and engaged with the first sun gear, and a first internal gear ring surrounding and engaged with the first planetary gears. The first sun gear is coaxially fixed to a rotary shaft of the motor. Meshing planes of the first sun gear and the first planetary gears are slanted with respect to the rotary shaft. Each of the first planetary gears is subjected to an externally-exerted first force and exerts a transverse component of force toward the rotary shaft on the first sun gear. The motor structure of the driving device is simplified, which makes the driving device have a more compact structure, lighter weight and lower cost.
