Abstract
The utility model relates to a cooling water pipe sealing structure of a rotary kiln riding wheel bearing pack, in particular to an improvement on the cooling water pipe sealing structure of the rotary kiln riding wheel bearing pack. The cooling water pipe sealing structure of the rotary kiln riding wheel bearing pack is simple in structure, good in sealing effect and low in production cost. The cooling water pipe sealing structure comprises a spherical surface tile, a bearing upper cover is arranged outside the spherical surface tile, a pipe connector is arranged on the spherical surface tile, and an opening is formed in the position, corresponding to the pipe connector, of the bearing upper cover. The cooling water pipe sealing structure is characterized in that a supporting pipe concentric with the pipe connector is fixedly arranged at the position, located outside the opening, on the bearing upper cover, an annular pressing cover is arranged on the end face of the supporting pipe through a bolt, an annular sealing mat is arranged between the pressing cover and the end face of the supporting pipe, and an inner hole of the sealing mat is in interference fit with the pipe connector.
Description
Technical field
The utility model relates to the improvement of the bearing of conveyor idler group water-cooling tube sealing configuration of rotary kiln.
Background technique
Bearing of conveyor idler group is the main support unit of rotary kiln, so the bearing of conveyor idler group that is thermal technology's heave-load device supporting kiln body due to kiln needs cooling water lasting cooling to work bearing shell, in equipment operation process, spherical bush meeting automatic fine is adjusted the gyration center of bearing of conveyor idler group, force and between water-cooling tube and bearing upper cover, need a flexible sealing configuration to prevent rainwater, foreign material and drench gradually water to enter bearing of conveyor idler group and cause accident, this mechanism still can guarantee sealing effect after also needing to possess the error occurring when absorbing because of processing and installing.But, as shown in Figure 3, there is following shortcoming in sealing configuration at present: 1, Sealing does not reach the effect of sealing in the time that adjustment is installed.Former Sealing 11 mostly is bowl-type rubber and makes, and because bearing upper cover 2 is that welding or cast structure seal face mostly are cylndrical surface or complicated song, the rubber seal 11 of bowl-type is difficult to adjust whole curved surface is sealed when mounted.
2, Sealing 11 needs special mould to make, and makes complicated.
3, amount of deformation is uncontrolled when mounted for Sealing 11.Because pipe joint 6 and the connecting thread of spherical bush 1 mostly are sealed pipe screw thread, the screwing length of sealed pipe screw thread is substantially fixing, in addition there is unavoidable deviation in making in bearing upper cover 2, cause in the time of fastening pipe joint 6, cannot oppress accurately Sealing 11 and produce applicable amount of deformation to reach the effect of sealing.
Summary of the invention
The utility model is exactly for the problems referred to above, provides a kind of simple in structure, good sealing effect, the supporting roller of rotary kiln bearing pack water-cooling tube sealing configuration of low production cost.
For realizing above-mentioned purpose of the present utility model, the utility model adopts following technological scheme, the utility model comprises spherical bush, spherical bush is outside equipped with bearing upper cover, on spherical bush, be provided with pipe joint, on bearing upper cover, be provided with opening corresponding to pipe joint, it is characterized in that: the outside that is positioned at described opening on bearing upper cover, be fixedly installed the support tube concentric with pipe joint, on the end face of support tube, be provided with annular gland by bolt, between gland and the end face of support tube, be provided with annular sealing gasket, the endoporus of sealing gasket is with pipe joint interference fit.
As a kind of preferred version of the present utility model, described gland inwall is set to inclined-plane corresponding to the edge of sealing gasket.
As another kind of preferred version of the present utility model, the upper end in described support tube is provided with bracing ring corresponding to sealing gasket.
The beneficial effects of the utility model: 1, the utility model sealing configuration has been realized from former curved surface sealing and become end face seal; Reliability significantly improves.
2,, because the utility model is simple in structure, in Installation and adjustment process, greatly reduce operator's labor intensity.
3, the sealing gasket of the utility model sealing configuration is changed conveniently, (existing structure need to could be changed after pipe joint dismounting).
4, the gasket structure using due to the utility model sealing configuration is simple, is easy to make, and changes existing Sealing and makes the problem that needs special mould, has reduced cost of production and the maintenance cost of equipment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Fig. 3 is existing supporting roller of rotary kiln bearing pack water-cooling tube sealed structural representation.
In accompanying drawing, 1 is that spherical bush, 2 is that bearing upper cover, 3 is that gland, 4 is that sealing gasket, 5 is that opening, 6 is that pipe joint, 7 is that bracing ring, 8 is that bolt, 9 is that support tube, 10 is that inclined-plane, 11 is existing Sealing.
Embodiment
The utility model comprises spherical bush 1, spherical bush 1 is outside equipped with bearing upper cover 2, on spherical bush 1, be provided with pipe joint 6, on bearing upper cover 2, be provided with opening 5 corresponding to pipe joint 6, it is characterized in that: the outside that is positioned at described opening 5 on bearing upper cover 2, be fixedly installed the support tube 9 concentric with pipe joint 6, on the end face of support tube 9, be provided with annular gland 3 by bolt 8, between the end face of gland 3 and support tube 9, be provided with annular sealing gasket 4, the endoporus of sealing gasket 4 is with pipe joint 6 interference fit.
As a kind of preferred version of the present utility model, described gland 3 inwalls are set to inclined-plane 10 corresponding to the edge of sealing gasket 4.
As another kind of preferred version of the present utility model, the upper end in described support tube 9 is provided with bracing ring 7 corresponding to sealing gasket 4.By the cooperation on bracing ring 7 and the interior inclined-plane 10 of gland 3, can make sealing gasket 4 and gland 3 fully fit, further improve sealing effect.
The utility model, by be provided with support tube 9 and bracing ring 7 on bearing upper cover 2, can carry out machining on the end face of support tube 9 and bracing ring 7, obtains good sealing plane, can increase substantially sealing effect.
