Be filled with one deck lubricating grease between the lower end surface of the upper-end surface of described rubber ring and lower spheric seat.
Be provided with flange outside the top of described carriage, the bottom of described rubber ring is set in the center hole of described carriage, and the top of rubber ring is positioned at above described flange; The upper end of described spring is set in the below of described flange.
Described gooseneck bracket is comprised of base frame, root and cylinder, and the periphery of described root is provided with vertical muscle, is used for strengthening its intensity, and described spring clip is located at described vertical muscle periphery, is used for fixing spring; Described cylinder is cone structure, and the interference fit by conical surface and rubber ring provides variable damping force.
The bottom of described suspension rod is provided with round boss, is used for blocking and the fixed derrick seat.
The utility model is comprised of the gooseneck bracket, spring, carriage, rubber ring and the lower spheric seat that are set in successively on suspension rod, and the round boss of the bottom of suspension rod just in time blocks gooseneck bracket; The lower end surface of the upper-end surface of rubber ring and lower spheric seat is respectively equipped with the annular muscle that matches, and makes between them and fixes by pressing; The hole wall of the center hole of rubber ring and lower spheric seat all has the annular muscle of friction damping force between increase and suspension rod; The bottom of rubber ring is set in the center hole of carriage, and its top is positioned at the flange top on carriage top; Below, the lower end that the upper end of spring is set in flange is fastened on the vertical muscle periphery of gooseneck bracket, respectively spring limited, and namely spring can only carry out fore and aft motion between the base frame of the flange of carriage and gooseneck bracket.
When load changes, the carriage that is fixed together, rubber ring drive spring and carry out fore and aft motion together with lower spheric seat, the cone column sleeve of gooseneck bracket is entered in the center hole of rubber ring, provide either large or small variable damping force according to the height size of its interference fit, thereby reach the effect of vibration damping and noise reduction.If it is large that load becomes, the vibration increase of machinery equipment, noise become large, and the spring in this moment vibration damping equipment will be further compressed, and the engagement height of the cone post of gooseneck bracket and rubber ring increases thereupon, thereby has increased friction damping force, the amplitude that reduces to vibrate; If load diminishes, the noise and vibration of machinery equipment is corresponding to diminish, and spring will extend accordingly, and the cone post of gooseneck bracket and the engagement height of rubber ring reduce thereupon, thereby has reduced the friction damping force of vibration damping equipment.So no matter the size of load or vibration, can be by changing the damping force of vibration damping equipment, the effect that reaches vibration damping, noise reduction is unanimously effective.
Another purpose of the present utility model is to provide a kind of rotary drum washing machine that comprises adaptive damping suspension rod vibration damping equipment.
Adaptive damping suspension rod vibration damping equipment will be provided with in this washing machine, realized that washing machine is in the unequally loaded situation, vibration damping equipment provides the differentiated friction damping force, thereby realizes the vibration of washing machine slow-speed of revolution resonance region when the heavy load dehydration starts, in the situation that large damping decays rapidly; And in the high speed dewatering stage during underload, in little damping situation, the generation of vibration of dehydration barrel is effectively isolated, be unlikely to make vibration to be delivered on the washing machine box body, thereby reduce the amplitude of casing, reach the whole dehydration smooth running of assurance washing machine under various loads.
