Abstract
DC60(20/03/57) สิ่งที่ได้จัดเตรียมนี้เป็นแบริ่งเผาผนึกซึ่งทำให้สามารถลดค่าใช้จ่ายโดยการลดปริมาณ การใช้ทองแดง,มีความดีเยี่ยมในลักษณะสมบัติการเดิมเคลื่อนเริ่มแรกและความเงียบ,และ มีความทนทานสูงผงวัตถุดิบซึ่งรวมถึงผงเหล็ก,ผงทองแดงชนิดแบน,ผงโลหะจุดหลอมเหลวต่ำ, และแกรไฟต์จะได้รับการโหลดเข้าไปในแบบหล่อและวัตถุอัดแน่นชนิดกรีนได้รับการก่อขึ้นรูป ภายใต้สถานะที่ผงทองแดงชนิดแบนได้รับการทำให้ยึดติดบนพื้นผิวแบบหล่อลำดับต่อมานั้น การเผาผนึกได้รับการดำเนินการโดยปราศจากการทำให้เหล็กในวัตถุอัดแน่นชนิดกรีนนี้ทำปฏิกิริยา กับคาร์บอนเพื่อที่ให้โครงสร้างเหล็กได้รับการก่อขึ้นรูปเป็นวัฏภาคเฟอร์ไรต์ในวิธีนี้สามารถทำให้ ได้มาซึ่งแบริ่งเผาผนึก(1)ซึ่งรวมถึงส่วนฐาน(S2)ที่มีทองแดงในปริมาณบรรจุสม่ำเสมอ,และ ชั้นพื้นผิว(S1)ซึ่งปิดคลุมพื้นผิวของส่วนฐาน(S2)และมีทองแดงในปริมาณบรรจุมากกว่าส่วนฐาน (S2)DC60(20/03/57) The prepared product is a sintered bearing which can reduce the cost by reducing the amount of copper used, has excellent initial slewing properties and silence, and has high durability. The raw material powders including iron powder, flat copper powder, low melting point metal powder, and graphite are loaded into the mold and Green compacts are formed. Under the condition that flat copper powder is subsequently bonded to the mold surface, the sintering is carried out without the iron in the Green compact reacting with carbon so that the iron structure is formed into a ferrite phase. In this way, it is possible to obtain a sintered bearing (1) which includes a base part (S2) with a uniform amount of copper filling, and a surface layer (S1) which covers the surface of the base part (S2) and has a higher amount of copper filling than the base part (S2).
