Mechanical-drive synergetic bearing device

The utility model relates to a bearing device, in particular to a mechanical-drive synergetic bearing device, which is characterized in that the mechanical-drive synergetic bearing device comprises a bearing frame (1), a round lightening hole (2), a needle roller bearing (3), fixing screws (4), needle roller bearing racks (5), a ball bearing (6), a needle roller bearing (7), a cone (8) and a round lightening hole (9). The needle roller bearing (3) is fixedly connected to the bearing frame (1) by the fixing screws (4), the bottom of the triangular bearing frame (1) is provided with the ball bearing (6), two sides of the needle roller bearing (3) are provided with the needle roller bearing racks (5), the acute angle alpha of the triangular bearing frame (1) is 10-60 degrees, two bottom angles beta 1 and beta 2 of the triangular bearing frame (1) are equal, and the bottom of the cone (8) is provided with the needle roller bearing (7). The bearing frame (1) is provided with the round lightening hole (2), and the cone (8) is provided with the round lightening hole (9). The mechanical-drive synergetic bearing device has the advantages of simple structure, low cost, safety, reliability, easy use, no loss and more than one time synergetic force.
