Abstract

本发明涉及一种集成行星轮减速装置的圆锥滚子轴承。该装置包括输入轴、内圈、滚动体、保持架、外圈、外圈太阳轮、行星轮、输入轴太阳轮、行星架、螺钉。两个轴承的内圈和外圈分别开有小凹槽,它们之间配合形成一个小腔体,滚动体和保持架安装在里面;两个轴承外圈轴向宽度比内圈宽,且成阶梯状构造,两个轴承外圈之间通过螺钉连接形成一个腔室,其中一个轴承外圈腔室内壁安装有齿轮,称为外圈太阳轮;输入轴与其中一个齿轮内圈过盈配合,且伸入腔室的输入轴的一头安装有齿轮,称为输入轴太阳轮;行星轮安装在两个太阳轮之间,并且由行星架支撑,行星架与另外一个轴承内圈过盈配合,也称行星架为输出轴。
The invention relates to a conical roller bearing of an integrated planetary gear speed reducing device. The device comprises an input shaft, inner rings, a rolling body, a retainer, outer rings, an outer ring sun gear, a planetary gear, an input shaft sun gear, a planetary carrier and a screw, wherein a small groove is formed in each of the inner ring and the outer ring of each of two bearings, and the small grooves are matched to form a small cavity in which the rolling body and the retainer are mounted; the axial width of the outer rings of the two bearings is larger than that of the inner rings, the outer rings of the two bearings are of stepped structures and are connected through the screw to form a chamber, and the inner wall of the chamber of the outer ring of one of the bearings is provided with a gear named as the outer-ring sun gear; the input shaft is in interference fit with the inner ring of one of the bearings, and the end extending into the input shaft of the chamber is provided with a gear named as the input shaft sun gear; and the planetary gear is arranged between the two sun gears and is supported by the planetary carrier, and the planetary carrier is in interference fit with the inner ring of the other bearing and is also named as an output shaft.
