Disclosed is a bearing assembly for a ball recirculating steering gear in a steering system, the bearing assembly comprising: a screw having a first end and an opposite second end; the thrust bearing is arranged at the first end of the screw rod and comprises a bearing race and a bearing steel ball; the bearing seat ring comprises a left half seat ring and a right half seat ring, the left half seat ring and the right half seat ring are respectively provided with an outer raceway, and the screw rod is provided with an inner raceway corresponding to the outer raceway of the left half seat ring and the outer raceway of the right half seat ring at or near the first end; when the thrust bearing is in an assembled state on the screw, the bearing steel ball is in contact with the outer raceway of the left half race, the outer raceway of the right half race and the inner raceway of the screw, and the left half race and the right half race are in contact with each other in the longitudinal direction of the recirculating ball type steering gear in a clearance-free mode. Therefore, the steering clearance of the steering system is minimized under the condition that grouping assembly is adopted. The invention further discloses a recirculating ball type steering gear comprising the bearing assembly.

    公开一种轴承组件,其用于转向系统中的循环球式转向器,轴承组件包括:螺杆,其具有第一端和相对的第二端;以及止推轴承,其设置在螺杆的第一端上并且包括轴承座圈和轴承钢球;轴承座圈包括左半座圈和右半座圈,左半座圈和右半座圈分别设置有外滚道,螺杆在所述第一端处或附近设置有分别与左半座圈的外滚道和右半座圈的外滚道对应的内滚道;当止推轴承在螺杆上处于已装配状态时,轴承钢球与左半座圈的外滚道、右半座圈的外滚道以及螺杆的内滚道接触,并且左半座圈和右半座圈在循环球式转向器的纵向方向上以没有间隙的方式彼此接触,从而在采用分组装配的情况下最小化所述转向系统的转向间隙。还公开一种包括上述轴承组件的循环球式转向器。
