Problems solved by technology
[0002] The slewing system of the transportation machinery requires the bearing to have a large bearing capacity, and the two flat rings can rotate relatively flexibly. The rotation between the flat ring and the roller bearing of the existing flat roller bearing is unstable, and the whole bearing is exposed and easily damaged. Resulting in a short service life and relatively high manufacturing costs

Embodiment Construction
[0008] Such as figure 1 As shown, the plane roller bearing in this embodiment includes a first cage 1 , a second cage 2 , a first flat ring 3 , a second flat ring 4 , a roller 5 and a housing 6 .
[0009] The first cage 1 and the second cage 2 are stacked on each other, and fourteen rollers 5 are mounted on the above two cages. The first flat ring 3 is arranged above the first cage 1, and the second flat ring 4 is arranged below the second cage 2, both of which are in contact with the outer surfaces of the fourteen rollers 5 . The shell 6 wraps the first cage 1 , the second cage 2 , the first flat ring 3 and a part of the second flat ring 4 . The above-mentioned cage is punched from 0.5mm thick steel plate, and the stacking height of the two cages is smaller than the diameter of the roller.

The invention discloses a plane roller bearing which is used for the rotating system of the transport machinery, can work stably and bear more force and has long service life and low production cost. The plane roller bearing comprises a first retaining bracket, a second retaining bracket, a first flat ring, a second flat ring and a plurality of rollers. The first retaining bracket and the second retaining bracket are overlapped; the rollers are arranged one the first retaining bracket and the second retaining bracket; the first flat ring is arranged above the first retaining bracket, and the second flat ring is arranged blow the second retaining bracket; and both the first flat ring and the second flat ring contact the outer side surfaces of the rollers. The plane roller bearing also comprises a shell which externally covers the first retaining bracket, the second retaining bracket, the first flat ring and part of the second flat ring. The first retaining bracket and the second retaining bracket and produced by punching thick steel plates of 0.5 mm, and the overlapping height of the first retaining bracket and the second retaining bracket is less than the diameter of each roller.
Description
technical field [0001] The invention relates to a bearing, in particular to a plane roller bearing. Background technique [0002] The slewing system of the transportation machinery requires the bearing to have a large bearing capacity, and the two flat rings can rotate relatively flexibly. The rotation between the flat ring and the roller bearing of the existing flat roller bearing is unstable, and the whole bearing is exposed and easily damaged. As a result, the service life is short, and its manufacturing cost is relatively high. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a plane roller bearing with stable working state, long service life, large bearing capacity and low manufacturing cost. [0004] The present invention includes a first cage, a second cage, a first flat ring, a second flat ring and rollers; the first cage and the second cage are stacked on top of each other, and several rollers are instal...
