Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figures 1-5, the utility model provides a technical solution: a new type of stacked sealed bearing, including an outer ring 1 and an inner ring 2, the bottom of the outer ring 1 is fixedly connected with a lower seal 3, and the inner ring 2 is provided with a There are ball grooves 4, and there are multiple sets of ball grooves 4 in a regular circular array. The ball grooves 4 are movable with balls 5, and the outer ring 1 includes a fixing part 101 and a split part 102, wherein the top of the inside of the fixing part 101 is set There is an annular gap matching the shape of the split piece 102, and a first internally threaded hole 6 is opened through the surface of the fixing piece 101. The second internally threaded hole 7, the first internally threaded hole 6 and the second internally threaded hole 7 are connected with a screw 8, and the first internally threaded hole 6 and the second internally threaded hole 7 are in a regular annular array and are provided with multiple groups. The surface of 8 is connected to the inner wall surface of the first internally threaded hole 6 and the inner wall surface of the second internally threaded hole 7 through a thread structure, and is connected to the first internally threaded hole 6 and the second internally threaded hole 7 through a screw rod 8, so that the fixing member 101 It is fixedly connected with the split part 102.
