Embodiment Construction
[0020] The present invention will be further described below in conjunction with embodiment and accompanying drawing.
[0021] Such as figure 1 with 2 As shown, a coaxial multi-layer, multi-stage central drive type electric drive system includes a fixed shaft 2, which is used to support the entire electric drive system, and a rotating sleeve 3 extending along its length is sleeved on the fixed shaft 2. When the rotating sleeve 3 is working, it rotates relative to the fixed shaft 2. The rotating sleeve 3 is provided with a power source 4, an output component 5 and a reduction mechanism 6 in sequence from left to right. When the integrated electric drive system is working, the power source 4 drives the rotating sleeve. 3 rotation, the rotation speed of the rotating sleeve 3 is decelerated by the deceleration mechanism 6 to drive the output part 5 to rotate, that is, the effective power output is performed at the middle position of the electric drive system, and the setting of t...

The invention discloses a coaxial multi-layer multi-level center drive type electric drive system. A fixing shaft is sleeved with a rotation sleeve in a rotation fit manner. The rotation sleeve is sequentially provided with a power source, an output component and a speed reduction mechanism in the length direction. The power source is used for driving the rotation sleeve to rotate, the output component rotationally sleeves the rotation sleeve, and the speed reduction mechanism is used for transmitting the rotation of the rotation sleeve to the output component in a decelerating manner. A speedreduction shaft of the speed reduction mechanism is provided with a first speed reduction gear, a sliding sleeve and an elastic element. The ends, getting close to each other, of the sliding sleeve and the first speed reduction gear are provided with an arc inner concave structure and an arc outer convex structure correspondingly, the arc inner concave structure and the arc outer convex structureinteract with each other, the sliding sleeve can be driven to move in the axial direction of the speed reduction shaft, and the sliding sleeve is provided with a detection component for detecting axial displacement of the sliding sleeve. The coaxial multi-layer multi-level center drive type electric drive system has the beneficial effects that the mechanical transmission efficiency is high, the balance performance is good, controllability is good, the safety coefficient is high, the structure is compact, and the load of the drive system can be detected.
Description
technical field [0001] The invention relates to a drive system, in particular to a coaxial multi-layer and multi-stage central drive type electric drive system. Background technique [0002] The reducer is an independent component composed of gear transmission, worm transmission, and gear-worm transmission enclosed in a rigid shell. It is often used as a reduction transmission device between the prime mover and the working machine. It plays the role of matching speed and transmitting torque between prime mover and working machine or actuator, and is widely used in modern machinery. [0003] For the electric drive system with a deceleration mechanism, the power source and the deceleration mechanism are generally arranged side by side, which has defects such as the structure of the entire drive system is too large, and the overall force balance is poor. At the same time, since the above drive system uses the motor as the power source, it can detect the output load in real tim...
