Furthermore, the retainer is internally provided with oil-proof plates which are positioned at two sides of the rolling body.

Furthermore, the bottom of the retainer is provided with a heat absorbing plate which is connected with the inner ring, the retainer is connected with the outer ring through a heat conducting rod, and the surface of the outer ring is provided with a heat radiating plate.

Further, an oil quantity sensor is arranged on the surface of the retainer.

Furthermore, reinforcing plates are connected to two sides of the outer portion of the outer ring.

Compared with the prior art, the invention has the following beneficial effects:

1. this a loop wheel machine is supported with gyration adopts and sets up oil inlet, oil-out and oil mass inductor, can support inside refueling to the gyration, can be accurate with oil instil into the rolling element inside, can gyration support lubricate, guaranteed lubricated effect, and avoid the oil mass too much to cause the rolling element to rotate inconveniently, guaranteed that the gyration supports pivoted smooth and easy.

2. Through setting up absorber plate, heat conduction stick and heating panel, can absorb the heat that the inner circle produced then heat conduction dispels the heat to the outer lane surface, guarantee the homogeneity of gyration support inside temperature, avoid the gyration that local overheat leads to support inside unstability, prolonged the life of gyration support.

3. Because set up strengthening rib and gusset plate, the stability of multiplicable inner circle reduces the damage that the inner circle produced when wearing and tearing, plays the protection to the inner circle, has guaranteed the work of gyration support efficient, has increased the stability of whole gyration support through the gusset plate, has guaranteed the stability of gyration bearing structure, guarantees this kind of for loop wheel machine gyration support result of use and result of use, is fit for extensively promoting.
