The invention discloses a lightweight train wheel and a production process thereof, and belongs to the technical field of train wheel production. The bearing mainly comprises an inner ring, a weld-aid ring is welded outside the inner ring in a sleeving manner, and an outer ring is welded outside the weld-aid ring in a sleeving manner; the inner ring is made of an aluminum alloy material, the outer ring is made of a steel material, the weld-aid ring is an aluminum-steel composite plate, the aluminum alloy side of the weld-aid ring faces the inner ring, and the steel material side of the weld-aid ring faces the outer ring. The inner ring and the outer ring are fixed through welding, so that the train wheel has higher fixing strength, the whole train wheel is not prone to falling apart, the overall strength of the train wheel is ensured, and the safety of the train wheel is improved; meanwhile, the train wheel becomes a whole through welding and fixing, and flaw detection of the wheel can be more accurate. According to the light-weight train wheel and the production process thereof, the effect of improving the strength of the train wheel is achieved.

    本发明公开了一种轻量化火车轮及其生产工艺,属于火车轮生产技术领域。主要包括内圈,所述内圈外套设焊接有助焊圈,所述助焊圈外套设焊接有外圈;所述内圈由铝合金材料制成,所述外圈由钢材料制成,所述助焊圈为铝钢复合板,所述助焊圈的铝合金一侧朝向内圈,所述助焊圈的钢材料一侧朝向外圈。通过焊接将内圈与外圈固定,使火车轮具有更强的固定强度,让火车轮整体不容易散架,从而确保火车轮整体的强度,增加火车轮的安全性;同时,通过焊接固定,使火车轮成为一个整体,对于车轮的探伤能够更加精确。本申请的一种轻量化火车轮及其生产工艺达到增加火车轮强度的效果。
