Coaxial multi-stage gearbox

Abstract

The invention discloses a coaxial multi-stage gearbox. The coaxial multi-stage gearbox comprises a box body, wherein a driving device and a speed changing adjusting device are arranged in the box body; the speed changing adjusting device can be engaged with the driving device so that the driving device outputs various powers; the driving device comprises an input system and an output system; the input system comprises an input driving gear shaft; the output system comprises an output spindle which can be engaged with the input driving gear shaft and outputs power; the speed changing adjusting device comprises a clutch gear; and the output spindle penetrates through the clutch gear. The box body comprises a first shell; the output system comprises a driving output device and a driven output device; the driving output device comprises an output spindle and a first clutch inner gear ring which is fixedly arranged on a reverse side, which is opposite to the first shell, of the clutch gear; and the driven output device comprises a second clutch inner gear ring. The coaxial multi-stage gearbox has the advantages that a speed changing range is large, retardation efficiency is high, various powers can be output, speed changing in various grades is realized, and an infinite step speed changing range can be obtained.

Description

technical field [0001] The invention relates to a mechanical device, in particular to a speed reducer. Background technique [0002] The traditional reducer is delivered at a constant speed, while the gearbox can change the transmission ratio, rotation direction (such as reverse gear) and set neutral gear of the reducer. There are many structures and principles. For example, automobile gearboxes are divided into manual and automatic, and also divided into gear type and electric type. [0003] The transmission ratio is the ratio of the angular velocity of the two rotating components in the mechanism, also known as the speed ratio, which is equal to the ratio of the input shaft speed to the output shaft speed, that is, equal to the product ratio of all driven gear teeth to the product of all driving gear teeth. [0004] However, the transmission of the traditional reducer with variable speed function is relatively small, resulting in low reduction efficiency, and the scope of...

Problems solved by technology

[0004] However, the transmission of the traditional reducer with variable speed function is relatively small, resulting in low deceleration efficiency, and the scope of application is relatively single and limited. It still cannot meet many work requirements, resulting in certain limitations and inconvenience.
