Description
Technical field
The utility model belongs to the technical field of engine device, is specifically related to a kind of motor of model airplane damping base.
Background technique
Be arranged on the small end that the critical piece doing linear reciprocating motion in its inside of carry-on piston aviation engine has piston, wrist pin and connecting rod at present, along with the change of velocity of piston, they create reciprocal inertia force neither be constant.The inertial force of linear reciprocating motion part is delivered to base by motion, and the external driving crank of gas force and propeller cavitation rotate, its reaction force can be delivered to fuselage by engine foundation, because its direction constantly changes, and be directly proportional to speed, once uneven, the damage of starting the parts such as base, body will be caused.In addition, when engine-driving propeller cavitation, also can produce one and act on and start torsional vibration on base.The vibration that motor itself produces is inevitable, and conventional engine base be hard connection between frame, the vibration that motor produces effectively is not absorbed, and vibration can be delivered to fuselage by engine foundation, thus produces the resonance of motor and fuselage.
Model utility content
The utility model, for the deficiencies in the prior art, provides a kind of motor of model airplane damping base, effectively can reduce the impact of engine luggine on whole airplane, thus reduces the noise of motor, reduces airplane fault, improves service life of aeroengine.
The technical solution of the utility model is achieved in that a kind of motor of model airplane damping base comprises the engine foundation and set screw being provided with multiple mounting hole, it is characterized in that: the two ends symmetry of described mounting hole has through two conical bores mutually; Be respectively equipped with the vibration-absorbing rubber sleeve matched in described conical bore, this vibration-absorbing rubber sleeve end face exceeds described mounting hole end face; A columned positioning spacer coaxial with described mounting hole is also provided with between two described vibration-absorbing rubber sleeves; Also flat gasket is provided with outside described vibration-absorbing rubber sleeve; Described set screw is fixedly connected with motor through described flat gasket, positioning spacer successively from described mounting hole side.
Preferably, described vibration-absorbing rubber sleeve is made up of nitrile rubber.
Preferably, the tapering of described conical bore is 90 ° ~ 150 °.
Preferably, described mounting hole has four, is distributed on described engine foundation four angles.
The utility model solves the defect existed in background technique, has following beneficial effect:
The motor of model airplane damping base that the utility model provides, project organization is simple; Be very effective, by absorbing vibrational energy, effectively can reduce the impact of engine luggine on whole airplane, improves manipulation quality, reduces airplane fault, extend the working life of body parts, improve the reliability of aircraft.

Fig. 2 is the partial sectional view of motor of model airplane damping base perspective view;
In figure: 1-engine foundation, 2-vibration-absorbing rubber sleeve, 3-set screw, 4-flat gasket, 5-positioning spacer.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
A kind of motor of model airplane damping base as depicted in figs. 1 and 2, comprises the engine foundation 1 and set screw 3 that are provided with 4 mounting holes, and the two ends symmetry of mounting hole has through two conical bores mutually; Be respectively equipped with the vibration-absorbing rubber sleeve 2 matched in this conical bore, this vibration-absorbing rubber sleeve 2 end face exceeds the end face 2mm ~ 4mm of mounting hole; Also be provided with a columned positioning spacer 5 coaxial with mounting hole between two vibration-absorbing rubber sleeves 2, this positioning spacer 5 is made up of metallic material.Flat gasket 4 is also provided with outside vibration-absorbing rubber sleeve 2; Set screw 3 is fixedly connected with motor through flat gasket 4, positioning spacer 5 successively from mounting hole side.Vibration-absorbing rubber sleeve 2 is made up of nitrile rubber.The tapering of conical bore is 90 ° ~ 150 °, and the preferred tapering of the present embodiment is 120 °.
Principle of the present utility model is: utilize rubber itself to have delayed, damping and can carry out the feature of reversible large deformation, impacts for separating vibration and absorbing.The vibration produced when the engine operates through base, ripple major part of shaking absorb by the cover of cone rubber everywhere.The engine foundation of routine and hard between base are connected to become and be flexible coupling, the vibration that motor is produced effectively is absorbed, and therefore will effectively reduce the vibration of motor, improves service life of aeroengine.
Working procedure of the present utility model is: install the vibration-absorbing rubber sleeve 2 with tapering respectively in four mounting hole both sides of engine foundation 1, and install a positioning spacer 5 additional in the middle of vibration-absorbing rubber sleeve 2, the left and right sides is also fixed with flat gasket 4.Set screw 3 penetrates from mounting hole side, fixing firm with motor.Rubber sleeve inherently can play the effect of energy-obsorbing and damping, and the conical surface with the vibration-absorbing rubber sleeve 2 of tapering can also carry the torsion and vibration that all directions pass over.When the vibration passing produced when the engine operates is to engine foundation 1, vibration major part absorb by the cone rubber cover in eight mounting holes, therefore will effectively reduce the vibration of motor, improve service life of aeroengine, improve the reliability of aircraft.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
