Slewing bearing, axle assembly and operation machine
The invention relates to the field of operation machinery, and discloses a slewing bearing, an axle assembly and operation machinery. The slewing bearing comprises an inner ring, an outer ring, a ball body and a roller pin; wherein the outer ring is arranged on the outer side of the inner ring in a sleeving manner, a gap is formed between the inner wall of the outer ring and the outer wall of the inner ring so as to form a first roller path, and the roller pin is arranged in the first roller path; a first ring groove is formed in the portion, located in the first roller path, of the inner wall of the outer ring, a second ring groove is formed in the portion, located in the first roller path, of the outer wall of the inner ring, the first ring groove and the second ring groove are oppositely arranged and define a second roller path, and the ball is arranged in the second roller path. Due to the fact that the roller pins are in linear contact with the first roller paths, the contact area of the roller pins and the first roller paths is larger, the roller pins can share the pressure of the balls, the stress area of the inner ring and the stress area of the outer ring are increased, the situation that the inner ring or the outer ring is damaged by the balls or the roller pins is reduced, and the radial bearing capacity of the slewing bearing is improved.
本发明涉及作业机械领域，公开了回转支承、车桥总成及作业机械。回转支承，包括内圈、外圈、球体和滚针；其中，外圈套设在内圈的外侧，外圈的内壁与内圈的外壁之间具有间距，以形成第一滚道，滚针设于第一滚道内；外圈的内壁位于第一滚道内的部分设有第一环槽，内圈的外壁位于第一滚道内的部分设有第二环槽，第一环槽和第二环槽相对设置并围成第二滚道，球体设于第二滚道内。由于滚针与第一滚道之间为线接触，使得滚针与第一滚道的接触面积更大，因此滚针能够分担球体的压力，并增大内圈和外圈的受力面积，从而减少内圈或外圈被球体或滚针硌伤或压坏的情况发生，提高回转支承的径向承载能力。
