Abstract
The utility model relates to a grinding roller with good sealing property. The grinding roller comprises a grinding roller shaft; a bearing pack is connected onto the outer wall at one side of the grinding roller shaft in a sheathed manner; a hub is connected onto the bearing pack in a sheathed manner; a press ring is fixedly connected to one side of the hub; a roller sleeve is connected onto the hub in a sheathed manner; a grinding head is connected onto the outer wall of the roller sleeve in a sheathed manner; a transparent cover is fixedly connected to the other side of the hub; the inner wall of the transparent cover is connected with a first sealing ring, and the outer wall of the transparent cover is provided with a second sealing ring; a fixed ring is arranged beside the first sealing ring and is connected onto the grinding roller shaft in a sheathed manner; the inner wall of the fixed ring and the inner wall of the first sealing ring are respectively connected with a metal sealing structure in a matching way; each metal sealing structure comprises two metal framework rings and a floating seal. According to the grinding roller with good sealing property, vibration is generated in the grinding process, so that the two metal framework rings, which are in contact with each other, are mismatched; after the contact end surfaces of the two metal framework rings are set to be in convex arc shapes in an opposite way, the two metal framework rings are well in contact with each other even if being slightly mismatched, so that the sealing effect is greatly improved.
Description
Technical field
The utility model relates to a kind of grinding roller, relates in particular to a kind of grinding roller with good sealing property.
Background technology
Large-scale material grinder can produce a large amount of powders in abrasive process, and grinding roller meeting in abrasive process produces vibrations, causes bearing inner sealing hydraulic performance decline, and in long-term use, powder can enter the bearing inside of grinding roller, and machine is caused to damage.
Utility model content
The technical problems to be solved in the utility model is: in order to solve grinding roller, shake cause sealing property to decline in abrasive process, powder easily enters the problem in sealing ring, and the utility model provides a kind of grinding roller with good sealing property to solve the problems referred to above.
The utility model solves the technical scheme that its technical problem adopts: a kind of grinding roller with good sealing property, comprise shaft of grinding roller, on the outer wall of one side of described shaft of grinding roller, be socketed with bearing group, in described bearing group, be socketed with wheel hub, a side near shaft of grinding roller end on described wheel hub is fixedly connected with pressure ring, on described wheel hub, be socketed with roller shell, on described roller shell outer wall, be socketed with abrasive head, a side away from shaft of grinding roller end on described wheel hub is fixedly connected with transparent cover, on described transparent cover inwall, be fixedly connected with the first sealing ring, on the outer wall of described transparent cover, be provided with the second sealing ring, the other retainer ring that is provided with of the first described sealing ring, described retainer ring is socketed on shaft of grinding roller by screw, on the inwall of described retainer ring and on the inwall of the first sealing ring, be connected with shape metallic leak-proof structure, described shape metallic leak-proof structure comprises the floating seal on two metallic framework rings that are in contact with one another and metallic framework ring outer wall.Retainer ring inwall and one of them metallic framework ring outer wall form a dead slot, the first sealing ring and another metallic framework ring outer wall also form a dead slot, floating seal is separately positioned in two dead slots, in machine running process, grinding roller shake, two metallic framework rings are in contact with one another extruding, and sealing effectiveness can not be much affected.
It is circular-arc that the end face that two described metallic framework rings contact is relatively set into evagination.Grinding roller produces vibrations in abrasive process, cause two raw dislocation of the metallic framework environment-development contacting, but the end face that two metallic framework rings contact be arranged to evagination circular-arc after, even if there is trickle dislocation, still can be good at being against together, stop entering of dust, sealing effectiveness is improved greatly.
The beneficial effects of the utility model are; the utlity model has the grinding roller of good sealing property; in abrasive process, produce vibrations; cause two raw dislocation of the metallic framework environment-development contacting; but the end face contacting of metallic framework ring be arranged to evagination circular-arc after; even if there is trickle dislocation; still can be good at being against together; stop entering of dust; sealing effectiveness is improved greatly; add the multiple protective of the first sealing ring and the second sealing ring outward, make sealing effectiveness very good, can extend the life-span that grinding roller is used.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the structural representation that the utlity model has the optimum embodiment of grinding roller of good sealing property,
Fig. 2 is the enlarged drawing at A place in Fig. 1.
In figure 1, shaft of grinding roller, 2, bearing group, 3, wheel hub, 4, pressure ring, 5, roller shell, 6, abrasive head, 7, transparent cover, the 8, first sealing ring, 9, retainer ring, 10, metallic framework ring, 11, floating seal, the 12, second sealing ring.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model is only described in a schematic way, so it only show the formation relevant with the utility model.
As shown in Figure 1-2, a kind of grinding roller with good sealing property of the utility model, comprise shaft of grinding roller 1, on the outer wall of one side of shaft of grinding roller 1, be socketed with bearing group 2, in bearing group 2, be socketed with wheel hub 3, a side near shaft of grinding roller 1 end on wheel hub 3 is fixedly connected with pressure ring 4, on wheel hub 3, be socketed with roller shell 5, on roller shell 5 outer walls, be socketed with abrasive head 6, a side away from shaft of grinding roller 1 end on wheel hub 3 is fixedly connected with transparent cover 7, on transparent cover 7 inwalls, be fixedly connected with the first sealing ring 8, on the outer wall of transparent cover 7, be provided with the second sealing ring 12, the other retainer ring 9 that is provided with of the first sealing ring 8, retainer ring 9 is socketed on shaft of grinding roller 1 by screw, on the inwall of retainer ring 9 and on the inwall of the first sealing ring 8, be connected with shape metallic leak-proof structure, shape metallic leak-proof structure comprises the floating seal 11 on two metallic framework rings 10 that are in contact with one another and metallic framework ring 10 outer walls, it is circular-arc that the end face that two metallic framework rings 10 contact is relatively set into evagination.
Grinding roller produces vibrations in abrasive process, cause two metallic framework rings 10 that contact to misplace, but the end face that two metallic framework rings 10 contact be relatively set into evagination circular-arc after, even if there is trickle dislocation, still can be good at being against together, stop entering of dust, sealing effectiveness is improved greatly.
