The invention discloses a maintenance-free agricultural machine hub bearing. The maintenance-free agricultural machine hub bearing comprises a flange outer ring, a roller bearing, a connecting shaft and dustproof covers; the flange outer ring is arranged outside the roller bearing in a sleeving mode to form an overall-type rolling structure; the connecting shaft penetrates through the roller bearing; the dustproof covers are arranged at the two ends of the connecting shaft in a sleeving mode and matched with the flange outer ring; and grooves are formed in the large-diameter end and the small-diameter end of the flange outer ring correspondingly, one sides of the dustproof covers are provided with extending edges perpendicular to the cover body direction, and the extending edges of the dustproof covers are matched with the interior of grooves in the flange outer ring in an inserted mode. According to the maintenance-free agricultural machine hub bearing, through the design of a labyrinth-type matched structure of the flange outer ring and the dustproof covers, rainwater and slurry can be further prevented from eroding an oil seal, the service life of the oil seal is effectively prolonged, thus the sealing effect of the whole hub bearing is further enhanced, the service life is prolonged, and the practicability is high.

    本发明公开了一种免维护农机轮毂轴承,包括:法兰外圈、滚子轴承、连接轴和防尘盖,所述法兰外圈套置在所述滚子轴承外,形成整体式滚动结构;所述连接轴贯穿所述滚子轴承;所述防尘盖套置在所述连接轴的两端,并与所述法兰外圈配合,所述法兰外圈的大直径端和小直径端均开设有凹槽,所述防尘盖的一侧带有垂直于盖体方向的延伸边,所述防尘盖的延伸边插入配合到所述法兰外圈的凹槽内。本发明一种免维护农机轮毂轴承,通过法兰外圈与防尘盖的迷宫式配合结构的设计,能够进一步防止雨水和泥浆侵蚀油封,有效延长了油封的使用寿命,从而进一步增强整个轮毂轴承的密封效果,提高服役寿命,实用性强。
