The model utility content
Technical problem to be solved in the utility model is the bearing that rational in infrastructure, the good seal performance of a kind of waterproof, anti-gas-leak, dust protection is provided for above-mentioned prior art present situation.
The utility model solves the problems of the technologies described above the technological scheme that adopts: the bearing of the waterproof anti-gas-leak of present embodiment, include the outer ring, inner ring, rolling element and seal ring, described rolling physical efficiency rollably places between outer ring and the inner ring, described seal ring places between outer ring and the inner ring and is positioned at the top and bottom of annular chamber, it is characterized in that: described seal ring includes the first seal ring and the second seal ring, the outer circumferential face of described the first seal ring and the inner circle wall of outer ring fix, the inner peripheral surface of described the first seal ring is supported on the periphery wall close contact of inner ring, the inner peripheral surface of described the second seal ring and inner ring periphery wall fasten together, described the second seal ring outer circumferential face is supported on the inner circle wall close contact of outer ring, and described the first seal ring is positioned at the second seal ring outside and is arranged above and below together, is formed with cavity between described the first seal ring and the second seal ring.
As improvement, be extended with partition in described the first seal ring, described partition is divided into each self-packing cavity one and cavity two with the cavity in the first seal ring and the second seal ring, be used for filling grease, and prevent internal grease or fluid to external leakage, also can prevent extraneous dabbling or the intrusion of dust.
Improve, described partition is conical partition again, and described partition is supported on the surperficial close contact of the second seal ring from the first seal ring oblique stretching out in middle part, thus the space between dynamic seal (packing) ground bridge joint bearing and the seal ring.
Improve, the first seal ring outer circumferential face is in the annular groove of setting with the outer ring inwall of the first seal ring outer circumferential face opposite position, compact structure again.
Improve, the second seal ring inner peripheral surface is in the annular cavity of setting with the inner ring inwall of the second seal ring inner peripheral surface opposite position again.
Improve again, the upper liner of described the first seal ring has tinsel skeleton one, increase the intensity of seal ring, do not made it easy to wear or scratch, thereby guaranteed good sealing effect, and this seal ring is not yielding, durable in use, make things convenient for greatly the installation of seal ring, better guarantee the assembling and positioning of seal ring, guarantee sealing effect, the lubricant medium that can be good at satisfying lubrication system does not leak or seepage.
Improve, the upper liner of described the second seal ring has tinsel skeleton two again.
Compared with prior art, the utility model has the advantage of: the bearing of described waterproof anti-gas-leak arranges the first seal ring, the second seal ring, seal the grease that bridge joint forms toroidal cavity and is filled with viscosity with the partition of the first seal ring, strengthened sealing effect, the lubricant medium that blocks in gas and the bearing bore on the one hand leaks or seepage; And the water, dust etc. in the running are also intercepted by these two toroidal cavities respectively on the other hand, so that these impurity are difficult to enter bearing cavity, greatly improved the reliability requirement of bearing, and be provided with the skeleton of sheet metal, increased the intensity of seal ring, thereby improved sealing effect and the life-span of Sealing, satisfied usage requirement.
