Description
Technical field
The utility model relates to locomotive, motor train unit cooling mechanism combined type vibration damping device, belongs to the heat transfer technology field.
Background technology
Locomotive, motor train unit cooling mechanism generally comprise following several critical component: filter, radiator, blower fan, casing etc., blower fan is installed in the casing by supporting seat, and whole cooling mechanism is fixed on the locomotive ground board support by the outer mount pad of casing or is lifted on the underfloor vehicle frame of motor train unit.At present, the general employing is rigidly connected between mount pad between the supporting seat in locomotive, motor train unit cooling mechanism blower fan and the casing, outside the casing and locomotive ground board support or the motor train unit vehicle frame, also has only a few to add a rubber tie plate that 5mm～10mm is thick between above-mentioned rigid connector.There is following shortcoming in above-mentioned connection mode: when cooling mechanism is worked, vibration and noise that the blower fan high speed rotating produces directly reach car body by being rigidly connected, may cause the fatigue damage of surrounding devices and structure on the one hand, excessive on the other hand vibration and noise will have a strong impact on passenger's rest, disturb passenger's normal life.
Summary of the invention
The purpose of this utility model is to overcome weak point of the prior art, for railway transportation equipment provides a kind of metallic elastic component combined type vibration damping device, realization elasticity is connected between the mount pad of make between the supporting seat in locomotive, motor train unit cooling mechanism blower fan and the casing, casing is outer and locomotive ground board support or the motor train unit vehicle frame, isolate the vibration of Natural vibration source, thus reach improve comfort of passenger, prolong cooling mechanism and around the purpose of relevant device and structural life-time.
This locomotive, motor train unit cooling mechanism with the structure of combined type vibration damping device are: inner sleeve is provided with elastic element outward, and the outer sleeve that elastic element is provided with the band mounting flange outward constitutes the combined type vibration damping device; At the inner sleeve upper surface lower carrier plate is set, overbolt is worn inner sleeve, lower carrier plate, locomotive ground board support or motor train unit vehicle frame, upper padding plate from the bottom to top successively, by the nut on it combined type vibration damping device is fastened on locomotive ground board support or the motor train unit vehicle frame; The outer sleeve bottom surface is provided with flange, is connected with the cooling mechanism mount pad by lag bolt.
Described inner sleeve is cylindrical, bottom surface band disc supporting plate, and inner sleeve outside face and elastic element fit tightly, and the inner sleeve inside face is a smooth surface, and outside face is provided with rib to outer lug along longitudinal axis.Bottom surface disc supporting plate is used to hold and applies a power that makes progress to elastic element, makes itself and outer sleeve keep fitting tightly.The inner sleeve inside face is a smooth surface, and diameter is greater than the diameter of built-in overbolt.Outside face is provided with rib to outer lug along longitudinal axis, is used to guarantee that elastic element can be along the circumferential direction not rotary shifted after being subjected to torsion.Transverse plane is higher than transverse plane on the elastic element on the described inner sleeve, and diff-H is δ 3.This design, when elastic element because of vibration deformation took place, the shock absorber outer sleeve did not contact with erection support generation rigidity, guaranteed effectiveness in vibration suppression.
Described elastic element main body is approximate positive truncated cone-shaped, the lower part of truncated cone-shaped is the rounding platform, its inside face and inner sleeve intimate are fitted, outside face and outer sleeve inside face fit tightly, all be higher than the respective planes of outer sleeve along two planes up and down of short transverse, diff-H is δ 1 and δ 2.This design makes elastic element along train is vertical certain amount of compression be arranged, and in the time of can avoiding train operation on the one hand, from the vibration of wheel track or impact and pass to cooling mechanism through vehicle frame, can completely cut off the vibration of blower fan on the other hand.
Described outer sleeve is approximate truncated cone-shaped, and the bottom surface is provided with flange, and flange can be oval, also can be circular or square, and outer sleeve inside face and elastic element intimate are fitted, and inside face is provided with inwardly protruded rib along the round platform generatrix direction.According to installing space size and cooling mechanism weight, the flange of outer sleeve bottom surface can be arranged to approximate ellipsoidal, also can be arranged to circular or square or other version.Outer sleeve inside face and elastic element intimate are fitted, and inside face is provided with inwardly protruded rib along the round platform generatrix direction, is used to guarantee that elastic element can be along the circumferential direction not rotary shifted after being subjected to torsion.
Described inner sleeve, elastic element, outer sleeve can directly be cast together, also can stick with glue together between three elements.Described combined type vibration damping device, its installation direction can be according to practical application Rotate 180 °.
Described elastic element can adopt elastomeric material, also can adopt the elastomeric material that utilizes blending technology or technology such as modification technology or carbon black situ-formed graft rubber technology to make.Described combined type vibration damping device, other component materials adopts steel.
Combined type vibration damping device of the present utility model, when train operation, cooling mechanism work, the vibration that the cooling mechanism blower fan produces is passed to outer sleeve by the flange on the outer sleeve, and outer sleeve is being given elastic element with this transfer of vibration, elastic element produces deformation, absorbs or this vibration that decays.Vice versa, from the vibration or the impact of wheel track or the generation of other focus, passes to inner sleeve by lower carrier plate during train operation, and inner sleeve should vibrate or impact and pass to elastic element, and elastic element produces deformation, absorbs or this vibration that decays.Thereby realize the purpose of vibration and noise reducing.
The advantage of the utility model combined type vibration damping device is, by structure design, adjust rubber performance, and different rigidity requirement on three directions in the time of can satisfying train operation; The modular ratio metal of elastic element is little a lot, can produce bigger elastic deformation, two kinds of functions that have decay and absorb vibration and impact, good damping result; This combined vibration-damping device does not have slipper, does not have abrasion, is easy to maintenance; In light weight, easy for installation, be easy to dismounting.This combined type vibration damping device can improve comfort of passenger, the prolongation cooling mechanism reaches relevant device and structural life-time on every side.
