Abstract
The utility model discloses an internal combustion locomotive diesel generating set combined type vibration damping device. The internal combustion locomotive diesel generating set combined type vibration damping device comprises a diesel arranged on a baseboard of a locomotive body. Rubber shock absorbers are symmetrically arranged on two sides of the diesel. The internal combustion locomotive diesel generating set combined type vibration damping device is characterized in that inclined hydraulic shock absorbers are further symmetrically arranged on two sides of the diesel. The internal combustion locomotive diesel generating set combined type vibration damping device uses rubber elasticity of the rubber shock absorber to baffle vibration of a generating set, and meanwhile uses the inclined hydraulic shock absorbers to absorb vibration energy of the generating set. The inclined hydraulic shock absorbers has a resistance damping character, can reduce vertical and transverse high frequency and low frequency vibration of the generating set, and thus reducing locomotive vibration, eliminating resonance phenomenon of local position or the accessories, slowing down untimely fatigue of structure intensity of mechanical parts such as a synchronous main generator, diesel, and locomotive, prolonging service life, and improving comfortableness of steward.
Description
Technical field
The utility model relates to a kind of vibration damping equipment, particularly relates to a kind of combined damping device of diesel locomotive diesel generator set.
Background technique
At present, internal combustion locomotive newly make, overhaul and in repair diesel generating set test after, diesel generating set is used four bearings with rubber shock absorber to be installed in to carry out vibration damping on the locomotive car body, its vibration damping mode only adopts rubber shock absorber, effectiveness in vibration suppression is undesirable.
Internal combustion locomotive has two large vibration sources on the locomotive when operation, namely diesel engine itself is a uneven mechanism of motion, produces easily vibration; Main generator rotates, and also can produce vibration.Because Vibration of Diesel Generator Set, may form resonance at local location or accessory and cause high vibration.Locomotive adopts integral body, and crackle, welding are bad if the vehicle frame part has, distortion etc., cause vehicle frame rigidity inadequate, and the diesel generating set basis is insecure, larger vibration also occurs easily.Now only cushion the vibration of diesel generating set with rubber shock absorber, locomotive occurs causing whole locomotive vibration because of Vibration of Diesel Generator Set when actual motion easily.
Therefore, do not reach in the situation of desirable effectiveness in vibration suppression at single employing rubber shock absorber, those skilled in the art demands designing more preferably vibration damping equipment of a kind of effectiveness in vibration suppression urgently.
The model utility content
The purpose of this utility model just provides a kind of diesel locomotive diesel generator set combined damping device, adopt the mode of rubber shock absorber and tilting dydraulic shock absorber combination to carry out vibration damping, effectiveness in vibration suppression is better, can overcome above-mentioned the deficiencies in the prior art part fully.
The purpose of this utility model realizes by following technical proposals:
A kind of diesel locomotive diesel generator set combined damping device comprises the diesel engine that is arranged on the hull bottom plate, and the diesel engine bilateral symmetry is provided with rubber shock absorber, it is characterized in that: also be symmetrically arranged with the tilting dydraulic shock absorber in the diesel engine both sides.
Further, described diesel engine sidewall is provided with fitting seat, and correspondence is provided with lower fitting seat on the hull bottom plate, and tilting dydraulic shock absorber two ends are inclined between diesel engine sidewall and the hull bottom plate by upper and lower fitting seat.
Further, the oil hydraulic cylinder external diameter of described tilting dydraulic shock absorber is φ 50mm～φ 300mm.
Further, described tilting dydraulic shock absorber has more than 2 pairs, span 50mm～1000mm between adjacent two pairs of tilting dydraulic shock absorbers.
During the work of tilting dydraulic shock absorber, piston is to-and-fro motion in oil cylinder, produce the vibration damping resistance through orifice valve when fluid flows in piston cylinder, the tilting dydraulic shock absorber absorbs the vibrational energy of generator set simultaneously, and the vibrational energy of generator set is converted into the heat energy of fluid and dissipation.
The beneficial effects of the utility model are: simple in structure, reasonable in design, utilize the vibration of the rubber elasticity buffer dynamo group of rubber shock absorber, and utilize simultaneously the tilting dydraulic shock absorber to absorb the vibrational energy of generator set.The tilting dydraulic shock absorber has the vibration damping drag characteristic, can reduce the vertical and horizontal high and low frequency vibration of generator set, and then reduction locomotive vibration, eliminate local location or accessory resonance phenomenon, slow down the structural strength premature fatigue of the mechanical parts such as synchronous main alternator, diesel engine and car body, and increase the service life, improve crew's travelling comfort.
