technical field

The invention relates to the technical field of mechanical energy saving, in particular to a radial torque suction and discharge device.

Background technique

Torque (or torque) transmission is one of the basic forms to realize mechanical work transmission. Power, load and rotating shaft are the three basic elements of torque transmission. Generally speaking, power and load have their own intrinsic torsional characteristics, but their intrinsic torsional characteristics often do not match, resulting in mixed torque transmission, accompanied by reduced energy conversion efficiency of power and load, and torsional vibration. , torsional energy transfer loss, shortened device life and reduced reliability and other negative effects.

For the torque matching problem of load and power, traditional technologies have given a variety of solutions, but simple and thorough solutions are still lacking, and this situation has not been improved until the emergence of torque extractor technology. The torque absorber is the name of the new type of device according to the working principle, but it can also be named as torque adapter, torque damper, torque converter, torque coupler, universal torsion device, torque Vibrator or other names.

The spring needle structure of these schemes has basic properties and high-level properties. One of the main features is that the fixed support is used to constrain the movement of the moving support, so that the moving support only moves in the direction of the center line of the spring, and the direction of the force on the spring is parallel. on the centerline of the spring. This basic structure spring pin with high standard properties well satisfies the expected requirements in terms of spring force, but makes the torque extractor more complicated as a whole. In view of this, the present invention will start from the simplification of the motion constraints between the fixed bracket and the movable bracket, and combine with other aspects of the structure and function expansion, to provide more torque extractor solutions. The technical transformation scheme given in the present invention is also applicable to radial type and axial type torque suckers, but only the transformation of radial type torque suckers is described as an example.

One of the needle hub and the track is fixed, and the other is fixed on the suction and discharge shaft to keep rotating with it. The needle tip abuts or hooks on the track surface, and the needle tip slides or rolls along the track surface, driving the elastic needle to absorb or expel power. Without considering the influence of friction loss, moment of inertia and other non-ideal factors, the torque of the suction device is equal to or approximately equal to the rate of change of the energy of the bullet needle to the rotation angle, and the torque frequency is the least common multiple of the frequency of the rail surface and the frequency of the bullet needle. After a period of rotation angle , the sum of the accumulative suction work and the accumulative discharge work of the aspirator is 0. The springs are coil springs, leaf springs, rod springs or other non-coil springs.

The elastic needle is a flexible mechanical energy storage element in the torque suction machine, which is composed of a fixed support, a movable support and a spring. The spring needle absorbs and expels work through the spring, and converts the change of the radius of the rail surface into the expansion, bending and/or twisting rebound of the spring through the moving support, and is installed on the needle hub through the fixed support. Considered to be part of the needle hub. The needle tip is arranged on the movable bracket, and is the part or element that keeps the elastic needle in relative contact with the rail surface. The shape change of the pin is governed by the combination of the shape change of the track element in the torque sucker and the change of the rotation angle of the torque sucker shaft. The spring needle can also be applied to other mechanical devices with the function of suction and discharge. Through the cooperation of the spring needle and the track surface, the spring is used as the energy storage element to realize the quantitative correlation change between the torque of the suction device and the spring energy. The function of eliminating instantaneous torque vibration in equal amounts with timing has the function of quantitatively generating periodic instantaneous torque vibration on demand.
