弹性金属塑料轴瓦的生产方法
摘要：
本发明公开一种弹性金属塑料轴瓦的生产方法，其特征在于包括如下步骤：制成在金属丝弹性垫上嵌有表面塑料层的瓦面；将瓦面置于密闭容器中，在真空度为6～15Pa的条件下将金属丝弹性垫浸入液态焊料中，使焊料填入金属丝弹性垫内的孔隙中；将含有焊料的瓦面钎焊在钢瓦基上。本发明克服了现有技术的“金属丝弹性垫中必须留有一定孔隙，才能获得较大的弹性模量”的技术偏见，采用在真空条件下向金属丝弹性垫内的孔隙填充焊料的生产方法，使焊料的孔隙填充率大于95％，甚至可达100％。高孔隙填充率可避免在金属丝弹性垫中形成填料空洞区及孔隙填充深度不等的问题，提高了产品的弹性模量及均匀度，可提高5～10％，尤其适合于在重载工矿下使用。
摘要（英）：

The present invention discloses a production method of elastic metal plastic bush. It is characterized by that said production method includes the following steps: on the metal wire elastic pad makingbush surface in which a surface plastic layer is inlaid; placing the bush surface in a closed container, under the condition of that vacuum degree is 6-15 Pa soaking the metal wire elastic pad in liquid soldering material to make the soldering material be filled into pores in the metal wire elastic pad, then soldering the bush surface containing soldering material on the steel bush base.
