SCALLOP-RESISTANT TRACK LINK AND METHOD OF MAKING SAME

A track link (20) includes an elongate link body (32) formed of a link body material (76) that varies in hardness to form a first lower hardness zone (78), a second lower hardness zone (80), and a higher hardness zone (82). The higher hardness zone (82) includes an upper rail surface (44) of the elo...

Zusammenfassung:A track link (20) includes an elongate link body (32) formed of a link body material (76) that varies in hardness to form a first lower hardness zone (78), a second lower hardness zone (80), and a higher hardness zone (82). The higher hardness zone (82) includes an upper rail surface (44) of the elongate link body (32) and extends substantially throughout the elongate link body (32) outside of the first and second lower hardness zones (80), which surround the track pin bores (48,54). Related methodology for making a track link (20) is also disclosed. 一种履带链节(20)包括由链节主体材料(76)形成的细长链节主体(32)，该链节主体材料(76)的硬度变化以形成第一较低硬度区(78)、第二较低硬度区(80)和较高硬度区(82)。较高硬度区(82)包括细长链节主体(32)的上轨道表面(44)并且在围绕履带销孔(48、54)的第一和第二较低硬度区(80)之外基本贯穿细长链节主体(32)延伸。还公开了用于制造履带链节(20)的相关方法。
