It is fixed, further improve rigidity.
Vibration-damping supporting structure of the present invention further includes interior endless tube 2, and the interior endless tube 2 is threaded through in the reinforced pipe 31, described
Interior endless tube 2 is embedded in the cushion blocking 1, and 2 structure of interior endless tube is arranged in cushion blocking 1, can enhance vibration reduction support knot of the present invention
The axial rigidity of structure, and buffer function is played, while providing axial support, reduce the transmitting of vibration in the axial direction.
Preferably, the annular cross section of interior endless tube 2 includes multiple arcs raised section 21, and arc convex section 21 can increase and subtract
The contact area of vibration pad 1, improves radially and tangentially rigidity.
Vibration-damping supporting structure of the present invention further includes having outer endless tube 4, and outer endless tube 4 is set on 1 periphery wall of cushion blocking.It is preferred that
Ground, there are two outer endless tube 4 is set, one is located at the side of plate, another is located at the other side of plate.In the periphery of cushion blocking 1
It is arranged outer endless tube 4, the axial rigidity of vibration-damping supporting structure of the present invention can be enhanced, and play buffer function, while providing axial
Support reduces the transmitting of vibration in the axial direction.
Cushion blocking 1 include it is multiple axially through vibration damping hole so that cushion blocking 1 to a certain extent have deformability.
Cushion blocking 1 is axial to protrude above the outer endless tube 4, it is preferable that cushion blocking 1 is axial to protrude above the radially projecting shape in portion 11
At boss, the bottom end of outer endless tube 4 is shelved on boss.Projective structure is arranged axially and radially upper in cushion blocking 1, can slow down axis
Upward vibration.
During actual fabrication, support leg 3, cushion blocking 1, interior endless tube 2 and outer endless tube 4 can be structure as a whole, such as be subtracted
Vibration pad 1 is rubber pad, support leg 3, interior endless tube 2 and outer endless tube 4 can be bonded together by the vulcanization of rubber, rubber internal notches
Reduce the use of material, while playing limit, prevent excessive generations of vibration of compressor from hitting, increase support leg 3 and
