Abstract
The present utility model relates to a memorizing alloy composite damping bearing which consists of a memorizing alloy external layer and a babbit metal inner bushing. The dominant role of said memorizing alloy external layer is: at a high temperature the stress-induced martensite can absorb high-frequency vibration, and at a low temperature the ordinary martensite can absorb low-frequency vibration so as to reduce the noise and raise the machining precision. The role of the babbit metal inner bushing is pressure bearing, hard wearing and smooth running, and to pass the vibration coming from the main axle to the memorizing alloy external layer so that the vibration can be absorbed to make the main axle run smoothly.
Description
Affiliated technical field
The utility model relates to a kind of in-fighting type bearing shell.Especially memory alloy compostie damp bearing shell.Be specially adapted to absorb machine tool chief axis, clip nut, the high and low frequency vibration of motion component such as the bent axle of diesel engine.
Background technique
At present, the plain bushing of domestic use does not possess vibration absorption ability, thereby produces noise, reduces the processing precision.So far the domestic compostie damp bearing shell made from memory alloy of not seeing as yet.
Summary of the invention
Have the deficiency that can not absorb vibration in order to overcome prior art, the utility model provides a kind of memory alloy compostie damp bearing shell, to compensate its defect.
The technological scheme that its technical problem that solves the utility model adopts is: memory alloy compostie damp bearing shell is to be made of memory alloy skin and Babbitt internal layer axle bush.The outer field main effect of memory alloy is: when high temperature, and the stress martensite of inducting, absorbing high-frequency vibration; When low temperature, common martensite absorbs low-frequency vibration, reduces noise, improves machining accuracy.Babbitt internal layer axle bush mainly is: play pressure-bearing, and wear-resisting, the effect of smooth running.Skin is passed in the vibration that main shaft is produced simultaneously, so that its absorption, to guarantee the main shaft smooth running.
The beneficial effects of the utility model are: reliable operation, simple in structure, easy to use, according to the difference of temperature, absorbing high-frequency and low-frequency vibration reduce noise, improve machining accuracy.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Embodiment
In Fig. 1, memory alloy compostie damp bearing shell is by memory alloy outer 1 and Babbitt internal layer axle
In Fig. 1, memory alloy compostie damp bearing shell is to be made of memory alloy outer 1 and Babbitt internal layer axle bush 2.Memory alloy skin 1 is formed by casting, and with Babbitt internal layer axle bush 2 fusions that form with spun casting be one.
When this bearing shell matched work with machine tool chief axis, machine tool chief axis directly contacts with Babbitt internal layer axle bush 2, plays pressure-bearing, and was wear-resisting, the effect of smooth running.When hot operation, the dither that machine tool chief axis produces is passed to memory alloy skin 1 by Babbitt internal layer axle bush 2, the martensite absorbing high-frequency vibration of inducting of its stress; When low-temperature working, the low-frequency vibration that machine tool chief axis produces is passed to memory alloy skin 1 by Babbitt internal layer axle bush 2, and at this moment, the common martensite of its outer 1 inside absorbs low-frequency vibration owing to in-fighting is very big.So just can guarantee lathe smooth working under any operating ambient temperature, reduce noise, improve machining accuracy.
The outer CuAlBeX that adopts of memory alloy, CuZnAl, the CuAlMn alloy casting forms.
Claims (2)
1. a memory alloy compostie damp bearing shell is characterized in that, this bearing shell is to be made of memory alloy skin and Babbitt internal layer axle bush.
2. according to right 1 described memory alloy compostie damp bearing shell, it is characterized in that, the outer CuAlBeX that adopts of memory alloy, CuZnAl, the CuAlMn alloy casting forms.
