Description

A kind of damping foot pad and air conditioner

technical field

The utility model relates to the technical field of vibration reduction, in particular to a vibration reduction foot pad and an air conditioner.

Background technique

The damping pads mainly play the role of attenuating the transmission of the vibration of the compressor to the chassis of the external unit. At the same time, they also have the functions of bearing and positioning, and can ensure that the pipelines of the external unit of the air conditioner are not damaged during transportation or handling. The rationality of the structure and design parameters of the damping pad directly affects the noise generated by the vibration of the chassis of the air conditioner's external unit, and even affects its reliability during transportation.

In the prior art, the structure and installation form of the vibration-damping pads are shown in Figure 1. The positioning bolts 100 are spot-welded on the chassis 101 of the external machine, and pass through the vibration-damping pads 102 with a through-hole structure in the middle, and the compressor mounting plate The mounting hole of 103 cooperates with the mounting groove of the damping foot pad 102, and the nut with pad 104 is screwed to the polished rod part of the positioning bolt 100.

In order to ensure that the air conditioner does not generate abnormal noise problems during operation, a gap will be set between the inner hole of the vibration-damping foot pad 102 and the positioning bolt 100. Usually, the gap should not be too small to avoid the vibration-damping foot pad 102 and the positioning bolt. 100 contact, the vibration of the compressor will be transmitted to the chassis 101 of the external machine, and excessive noise will be generated; however, the gap should not be too large, otherwise the compressor will vibrate too much in the damping foot pad 102 when the compressor is turned on and off, which will easily cause pipeline stress Exceeding the standard, and in the process of transportation, it is easy to cause pipeline breakage and damage. At present, the size of the above-mentioned gap cannot be well grasped, and the best effect cannot be achieved.

In addition, in order to solve the problem of excessive axial sway distance of the compressor during the transportation of the external machine, the existing technology will set the distance between the lower end of the nut with pad 104 and the upper end surface of the damping foot pad 102 to be less than 2mm, but it is affected by the pipeline. Due to the influence of the external force applied by other parts, when the compressor is actually installed, the gap between the upper end surface of the individual damping foot pad 102 and the lower end of the nut with pad 104 will always exceed the requirement.

In addition, the existing damping pads 102 all use the structure of the installation groove to cooperate with the mounting hole of the compressor mounting plate 103, and the top of the vibration damping pad 102 needs to be squeezed into the mounting hole of the compressor mounting plate 103 during installation. , to ensure that the damping foot pad 102 will not fall off from the compressor mounting plate 103 . Since the outer diameter of the top of the damping foot pad 102 is larger than the diameter of the above-mentioned installation hole, it is difficult to smoothly insert it into the installation hole, which seriously affects the assembly efficiency of the air conditioner.

By installing the above-mentioned vibration-damping foot pad 12, after the vibration-damping foot pad 12 is assembled, the vibration of the compressor 11 during operation is transmitted to the vibration-absorbing body 1 through the mounting plate 111 and the metal plate 2 on the upper end of the vibration-damping foot pad 12, due to the rubber inside The friction between the molecules dissipates most of the vibration transmitted from the compressor 11 in the form of heat, so the vibration transmitted to the chassis 10 of the air conditioner through the damping pad 12 is effectively attenuated, which reduces the Noise generated by the chassis 10.

Since the main excitation direction of the compressor 11 is tangential when it is running, especially when the compressor 11 is running at low frequency, the tangential shaking of the compressor 11 is relatively large, so it is necessary to increase the tangential stiffness of the vibration-damping pad 12 while meeting the vibration-damping requirements , to effectively suppress the tangential vibration displacement of the compressor 11.
