The integrated nose cone inner bearing of the mining dump truck comprises a frame cross beam and a ball bearing, the ball bearing is arranged on the frame cross beam, and the outer wall face of the ball bearing is a spherical ring face; the ball bearing and the frame cross beam are of an integrally-formed structure. The invention further discloses a machining method of the integrated nose cone inner bearing of the mining dump truck and a mounting method of the integrated nose cone inner bearing of the mining dump truck. Stress accumulation at the connecting position of the ball bearing and the frame cross beam can be avoided, and the connecting strength of the ball bearing and the frame cross beam is enhanced. 本发明公开了一种矿用自卸车一体式鼻锥内轴承，包括：车架横梁、球轴承，球轴承设置在车架横梁上，球轴承的外壁面为球形环面；球轴承、车架横梁为一体成型结构。本发明还公开了一种矿用自卸车一体式鼻锥内轴承的加工方法以及矿用自卸车一体式鼻锥内轴承的安装方法。本发明能够避免球轴承和车架横梁连接位置的应力积聚，增强球轴承和车架横梁的连接强度。
