Balance shaft assembly

The invention discloses a balance shaft assembly. The balance shaft assembly comprises a first balance shaft (1),a second balance shaft (2) and a bearing inner race (3); a first connecting shaft (1b) arranged at one end of the first balance shaft (1); a second connecting shaft (2b) is arranged at one end of the second balance shaft (2); one end of the bearing inner race is connected with the first connecting shaft (1b) in a sleeved mode, and the other end of the bearing race is connected with the second connecting shaft (2b) in a sleeved mode; and the first balance shaft (1) and the second balance shaft (2) are connected together by the way of integration rotating. The balance shaft component utilizes the bearing inner race of a rolling bearing to connect the two balance shafts. Therefore, installation of the rolling bearing on a balancing shaft with a large diameter counter weight can be easily and conveniently achieved. 本发明公开了种平衡轴组件。所述平衡轴组件包括：第平衡轴(1)，在其端处设置有第连接轴(1b)；第二平衡轴(2)，在其端处设置有第二连接轴(2b)；以及轴承内圈(3)，其端套接在
