Further, described mounting base 1 bottom is provided with an annular boss 9.
Concrete, the internal diameter of the through hole of the internal diameter of rubber body 4 center inner sleeves 7 and fork auricular branch seat 6 boss side surfaces equals the external diameter of connecting screw rod 5.
Beneficial effect:
1, the thrust that airplane engine produces is in the course of the work delivered on motor scaffold by main erection joint, transmitting thrust not of auxiliary erection joint place, this just requires the isolation mounting of auxiliary mounting plane enough little compared with main mounting plane isolation mounting in the rigidity of thrust direction, and have again suitable rigidity to bear motor side direction and vertical load in other directions, this model utility adopts two symmetrical identical elastic components of installing as damping element, can realize axial low rigidity, meet well motor and subtracted the requirement that vibration isolation is installed.
2, the utility model adopts Split assembled structural type, realizes larger bearing capacity with small size rubber structure replacement large scale rubber assembly in parallel, has reduced die sinking cost, and has strengthened Economy and the maintainalbility of isolation mounting.
3, the utility model adopts combinatorial cylinders shape rubber structure, and select equidistant hyperbola to optimize rubber profile, and make it to bear each to load and moment of torsion, be especially suitable for bearing torsional load, in the time that motor exists high pulling torque, still can play well anti-vibration and shock effect.
4, the designed isolation mounting of the utility model selects high temperature and high damping resistant silicone rubber as vibration isolation element, and it still can keep good mechanical property at 170 ℃, can meet the higher operating temperature requirement of attachment face after motor.
