The bearing end cover is provided with an outer annular bulge loop formed on the inner side wall close to the outer end, an annular positioning groove is formed on the inner side wall of the outer annular bulge loop, the outer side edge part of the annular first sealing ring is nested in the corresponding annular positioning groove, the side wall part of the middle through hole of the first sealing ring is an inner side edge part, and the inner side edge part extends out of the annular positioning groove.
The utility model has the outstanding effects that:
the O-shaped sealing rings are arranged on the outer end face and the inner end face of the floating sealing ring, the sealing floating sealing ring is supported and fixed on the bearing end cover through friction force generated by extrusion deformation of the O-shaped sealing rings, sealing effect is achieved, the floating sealing ring is enabled to be located in the middle of the annular sealing groove through elastic recovery of the O-shaped sealing rings, and the floating sealing ring is not easy to deviate, so that sealing effect is guaranteed, and the sealing device is simple in structure and convenient to install.
Description of the drawings:
FIG. 1 is a schematic view of a partial structure of the present utility model;
fig. 2 is a partial enlarged view of fig. 1.
The specific embodiment is as follows:
1-2, a floating seal end cover for a sliding bearing comprises a bearing end cover 10, wherein an inner annular bulge loop 11 is formed on the inner side wall of the bearing end cover 10 close to the inner end, an outer annular bulge loop 13 is formed on the inner side wall of the bearing end cover 10 close to the outer end, an annular seal groove 12 is formed in the middle of the inner side wall of the inner annular bulge loop 11, a floating seal ring 20 is inserted into the annular seal groove 12, and the inner side wall of a middle through hole of the floating seal ring 20 extends out of the annular seal groove 12; the outer end surface and the inner end surface of the floating seal ring 20 are pressed against a seal ring 30, and the other side wall of the seal ring 30 is pressed against the inner end surface or the outer end surface of the corresponding side of the annular seal groove 12.
The outer end face and the inner end face of the floating seal ring 20 are both formed with annular locating grooves 21, the inner wall face of the annular locating groove 21 is an arc-shaped wall face, the seal ring 30 is an O-shaped seal ring which is partially nested in the corresponding annular locating groove 21, and the seal ring 30 is clamped between the inner wall face of the annular locating groove 21 and the inner end face or the outer end face of the corresponding annular locating groove 21.
When the floating sealing ring is used, the shaft body is inserted into the middle through hole of the floating sealing ring 20, the outer side wall of the shaft body is tightly attached to the inner side wall of the middle through hole, an annular groove is formed in the inner side wall of the middle through hole of the floating sealing ring 20, oil can be stored in the annular groove, the oil on the shaft body can be stored in the annular groove under the condition that the floating sealing ring 20 ensures sealing of the shaft body, the lubricating effect is achieved while leakage is prevented, the inner side wall of the middle through hole of the floating sealing ring 20 is prevented from being dry-ground with the shaft body, and the service life is guaranteed.
Further, a space 1 is provided between the side wall of the floating seal ring 20 and the inner side wall of the annular positioning groove 21.
Further, two annular positioning grooves 131 are formed on the inner side wall of the outer annular protruding ring 13, the outer side edge portion, i.e. the outer circle portion, of the annular first sealing ring 2 is nested in the corresponding annular positioning groove 131, and the side wall of the middle through hole of the first sealing ring 2 is an inner side edge portion, which extends out of the annular positioning groove 131. The side walls of the middle through holes of the two first sealing rings 2 are in smaller gaps or are attached to the outer side walls of the shaft body, so that double-layer sealing is realized.
