Abstract
The utility model discloses a damping device and particularly discloses a pump damping device for an engine hydraulic pump. The pump damping device comprises a rear plate, two left plates, two right plates, shock pads and bases. The right plates are symmetrically mounted on two sides of the rear plate. The left plates are mounted on the left sides of the right plates respectively. Mounting blocks are symmetrically mounted outside the left plates and the right plates respectively. One shock pad is mounted below each mounting block. One base is mounted below the shock pad. Two bolts are symmetrically mounted on the two sides of the mounting block of each right plate. Two bolts are mounted on the left side of each left plate. Two bolts are mounted in the middle of the rear plate. The pump damping device has the advantages that the device is simple in structure and convenient to use and mount and demount; pump damping helps transmit power between an engine and the hydraulic pump; accordingly, the service lives of the engine and the hydraulic pump are prolonged.
Description
Technical field
The utility model relates to a kind of damping device, particularly the whole damping device of a kind of engine liquid press pump.
Background technique
Because the restriction of operating conditions, the vibration and noise of engineering machinery is difficult to eliminate, but can weaken vibration by structure optimization design, damper mechanism is the emphasis problem of structural design always, the vibration of bulldozer mainly comes from three aspects: power system, running gear, vehicle body structure, the bulldozer motor adopts diesel engine, compare with petrol engine, vibrate more serious, because the cycle of the disequilibrium power of cylinder combustion atmospheric pressure and moving element changes, make crankshaft system and motor complete machine produce vibration, in the vehicle body structure of vehicle, because a large amount of welding structural elements that adopt thin plate class part, this structure easily forms new vibration source under the drive of power system and running gear, when its natural frequency when being subjected to vibration frequency consistent, also has resonance phenomenon, this all can shorten the working life of bulldozer, also bring difficulty for the driving of bulldozer, need to design the damping device that produces vibration position for this reason, traditional full hydraulic bulldozer, motor directly drives hydraulic pump works by vibration damper, motor and oil hydraulic pump be independent vibration damping separately, the vibration of motor and oil hydraulic pump is asynchronous, this has not only reduced motor, in the working life of oil hydraulic pump, also have influence between motor and the oil hydraulic pump and transmit power.
The model utility content
The utility model provides a kind of simple in structure in order to remedy the defective of prior art, the whole damping device of the convenient engine liquid press pump that uses.
The utility model is achieved by the following technical solution:
The whole damping device of a kind of engine liquid press pump, comprise back side panel, left sideboard, right sideboard, beam and base, described back side panel bilateral symmetry is equipped with right sideboard, left sideboard is equipped with in the right sideboard left side respectively, and fitting seat is equipped with in the outside of two left sideboards and two right sideboards symmetry respectively, and the fitting seat downside is equipped with beam, the beam downside is equipped with base, two bolts are equipped with in fitting seat both sides on right sideboard symmetry respectively, and two bolts are equipped with in the left sideboard left side, and two bolts are equipped with in the back side panel intermediate portion.
The beneficial effects of the utility model are: simple in structure, easy to use, and easy installation and removal, integral vibration damping is conducive to the transmission of power between motor and oil hydraulic pump, improves the working life of motor, oil hydraulic pump.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing is the structural representation of the whole damping device of the utility model engine liquid press pump
Among the figure, 1 left sideboard, 2 right sideboards, 3 back side panels, 4 fitting seats, 5 bases, 6 beams, 7 bolts.
Embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.The whole damping device of a kind of engine liquid press pump of this model utility, comprise back side panel 3, left sideboard 1, right sideboard 2, beam 6 and base 5, described back side panel 3 bilateral symmetry are equipped with right sideboard 2, left sideboard 1 is equipped with in right sideboard 2 left sides respectively, fitting seat 4 is equipped with in the outside of two left sideboards 1 and two right sideboards 2 symmetry respectively, fitting seat 4 downsides are equipped with beam 6, beam 6 downsides are equipped with base 5, two bolts 7 are equipped with in fitting seat 4 both sides on the right sideboard 2 symmetry respectively, two bolts 7 are equipped with in left sideboard 1 left side, and two bolts 7 are equipped with in back side panel 3 intermediate portions.The whole damping device of a kind of engine liquid press pump of this model utility, during use left sideboard 1 is connected by bolt 7, damping pad 6 with base 5 with four fitting seats 4 of right sideboard 2, left sideboard 1, right sideboard 2, back side panel 3, motor, oil hydraulic pump are connected as a whole, the integral body of carrying out motor, oil hydraulic pump by damping pad 6 is unified vibration damping again.
