Abstract
The invention discloses a torsional vibration damper recycling vibration energy in an electromagnetic mode. According to the structure of the torsional vibration damper, an abrasion reducing bush is arranged in an inner shell and an annular notch is formed in the bush and used for fixing a magnet inner core disc. Vibration damping liquid is injected in a circumferential welding gap between the inner shell and the magnet inner core disc. Communicated magnetic induction coils are wound around the surface of the shell. The vibration damper is closed through an outer shell. The two ends of one magnetic induction coil at the lower end of the inner shell serve as alternating current power output ends. The inner shell, the outer shell and the abrasion reducing bush are respectively of an annular shape. Energy generated by vibration of a crank is converted into electricity through the magnetic induction coils and is recycled. According to experimental measurement and calculation, in normal operation of an engine, 100W electricity can be recycled by the magnetic induction coils and can be sufficiently supplied to a vehicle for illumination. The principle and the structure are applied to a large vibration machine so that electricity up to kilowatts can be recycled. According to the torsional vibration damper recycling the vibration energy in the electromagnetic mode, the vibration damping purpose can be achieved, the vibration energy can be effectively recycled, and self-use electricity can be partially satisfied.
Description
Technical field
Engine vibration-damping technology of the present invention, is specifically related to a kind of device energy of torsional vibration being reclaimed with electromagnetic mode.
Background technique
As everyone knows, motor inevitably produces torsional vibration in work meeting in service, and this vibration makes machinery equipment Efficiency Decreasing, even causes the fatigue ruption of bent axle or transmission shaft, and especially in the motor of high speed, high pressure, situation is even more serious.Though the shafting torsional oscillation earthquake intensity sometimes causing because of Long-term Vibration does not reach the degree of crankshaft breakdown, the torsional deflection of bent axle will cause main axle bush to peel off scaling loss, and timing gear or other driven accessary destroy.In addition, the torsional deflection of bent axle also can make engine noise increase.Therefore, subduing torsional vibration is problem anxious to be resolved during engine design is manufactured.
Subduing the effective measures of torsional vibration is on bent axle, to install torshional vibration damper additional.The vibration damping mode of traditional silicone oil torshional vibration damper is by inertia disk is housed on antifriction bush, inertia disk designs according to the natural frequency of bent axle, when speed of crankshaft approaches resonance speed, the damping characteristic of inertia disk plays a role, and dissipates the energy that torshional vibration damper produces because of resonance.The defect that this vibration damping mode is brought is, the energy that crankshaft torsional vibrations produce sheds heat by the silicone oil of inertia disk outside, and its vibrational energy can not get effectively reclaiming and utilizing.If can reach on the basis of effectiveness in vibration suppression, again this energy is reclaimed simultaneously, will become the required of the industry.
Summary of the invention
The object of the invention is, a kind of torshional vibration damper that reclaims vibrational energy with electromagnetic mode is provided.Utilize the inertia magnet inner core changes of magnetic field that double vibrations produces in shock absorber casing, make inductor coil produce the electric current of alternation, thereby vibrational energy is changed into the device of electric energy.
Technological scheme of the present invention is as follows: the torshional vibration damper that reclaims vibrational energy with electromagnetic mode comprises: inner and outer shell, antifriction bush, magnet inner core disk, vibration damping liquid and magnetic induction coil etc.Its technological scheme is: inner housing is equipped with antifriction bush, and antifriction bush is provided with annular breach, and annular breach is used for fixing magnet inner core disk.In circumferential weld gap between inner housing and magnet inner core disk, be marked with vibration damping liquid.The surface of inner housing is tied with the magnetic induction coil of UNICOM, and vibration damper seals with frame.Inner and outer shell and antifriction bush magnetic are annular.
In the process of vibration damper vibration, because ring magnet inner core disk has inertia, the motion of disk has periodic hysteresis than the motion of inner housing all the time, so just exists relative movement between magnet inner core disk and inner housing.On inner housing surface, be wound with magnetic induction coil, be used for experiencing the change of magnetic field strength of internal magnets.When internal magnets produces motion, magnetic force line cutting magnetic induction coil, just portion produces alternating current in coil.This electric current changes this into direct current by being located at the rectification circuit of torshional vibration damper bottom, and this power supply can be directly used in use or the storage battery charging of motor circuit.
Feature of the present invention and beneficial effect are that the energy that engine luggine is produced changes electric energy into by magnetic induction coil and reclaimed.According to experiment test, calculate in normal working of engine work, electromagnetic induction coil can reclaim the electric energy of 100W, and this electric energy is enough to supply vehicle illumination.If this principle and structure applications, in larger vibrating machine, can be reclaimed to nearly other electric energy of multikilowatt.Electromagnetic energy reclaims torshional vibration damper, except reaching effective vibration damping object, makes crankshaft vibration energy be able to effective recovery, and part meets the personal electric energy of locomotive.

Embodiment
Below in conjunction with accompanying drawing and by embodiment, principle of the present invention and structure are further described.The structure that reclaims the torshional vibration damper of vibrational energy with electromagnetic mode is: inner housing 1 is equipped with antifriction bush 2, and antifriction bush is provided with annular breach, and annular breach is used for fixing magnet inner core disk 3.In circumferential weld gap between inner housing and magnet inner core disk, be marked with vibration damping liquid 4, the surface of inner housing is tied with the magnetic induction coil 5 of UNICOM, frame 6 sealings for vibration damper.The magnetic induction coil two ends of inner housing lower end are as Ac output terminal, and inner and outer shell and antifriction bush are annular, and what accompanying drawing showed is semicircle, and in figure, chain line is the center line of annular vibration damper.Adopt silicone oil as vibration damping liquid.
As embodiment, torshional vibration damper is by the annular inner and outer shell sealing and have two primary elements of magnet inner core disk and form, and the be magnetic disk of (inertia) of band can freely rotate round the lining of smooth abrasion-proof in housing.In toroidal shell and magnet inner core disk circumferential weld gap, fill with the damping fluid with damping characteristic simultaneously.Housing and magnet inner core disk pass through mould-forming, and then install coil, by inner housing lower end, winding wire are drawn, and are connected to external power supply.During use, by torsional vibration damper frame and crankshaft end close-coupled, make it and produce torsional vibration with bent axle.
