Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
See Fig. 1, Fig. 2, a kind of Biserial cylindrical roller bearing with sealing disclosed by the invention, include two inner rings 1,1-1, outer ring 2, be assemblied between inside and outside circle 1,1-1,2 this enforcement of rolling element 3(in rolling element be band convex roller).Be provided with outer ring raceway 2-1,2-2 inside described outer ring 2, outer ring two raceway is all located at inside outer ring.Described outer ring 2 raceway two bottom sides is provided with oil duct 2-3,2-4 that outer ring raceway is communicated with, and outer ring raceway axially inner side arranges rib 2-6,2-7, and the axial both sides of outer ring raceway arrange annular groove 2-8.Be provided with inner ring raceway outside described inner ring 1 and the rib 1-4 of inner ring raceway both sides is set, described inner ring 1, both sides between 1-1 and outer ring 2 are provided with black box 5, black box 5 location and installation is between inner ring 1,1-1 and outer ring 2, and the black box 5 of both sides forms the sealed chamber of Bearing inner sealing, rolling element 3 is installed inside two ends snap ring 4.
Described black box 5 includes rubber seal 5-1 and support frame 5-2.In the present embodiment, rubber seal 5-1 adopts nitrile butadiene rubber to make, and support frame 5-2 adopts SPCC steel plate to make, the serviceability temperature of nitrile butadiene rubber, water resistence, and every use feature such as wear resistance is comparatively good, and cost performance is high; The tensile strength of SPCC is higher, good rigidly.Be provided with the outer ring seal groove for rubber seal 5-1 location and installation inside described outer ring 2, rubber seal 5-1 connects the other end of one end relative to outer ring seal groove and inner ring 1,1-1 contact outside are sealed and matched.Some sealing lip 5-4 that rubber seal 5-1 includes and is positioned to be installed on assembly department 5-3 in the seal groove of outer ring for black box 5, be sealed and matched with inner ring 1 contact outside and the joint 5-5 of connection portion 5-3 and sealing lip 5-4, joint 5-5 is provided with the hard-wired mounting groove of the described support frame 5-2 of confession towards rolling element 3 one side.Certainly as the technological scheme that the present invention is feasible, described rubber seal 5-1 can one end be also sealing lip, the other end and support frame end connect and compose black box, the other end that support frame connects one end relative to rubber seal is arranged on outer ring, but under this vibrational power flow, on support frame, kiss-coating is less, and black box difficulty of processing is large, therefore the present invention adopts the first black box to arrange.
