Description
Technical field
The present invention 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, because kiln is that thermal technology's heave-load device is so the bearing of conveyor idler group of supporting kiln body needs cooling water to continue the cooling of work bearing shell, the gyration center of spherical bush meeting automatic fine adjustment bearing of conveyor idler group in equipment operation process, force and to need a flexible sealing configuration to enter bearing of conveyor idler group cause accident to prevent rainwater, foreign material and to drench gradually water between water-cooling tube and bearing upper cover, this mechanism still can ensure sealing effect after also needing to possess the error occurred when absorbing because of processing and install.But, as shown in Figure 3, there is following shortcoming: 1, Sealing does not reach the effect of sealing when mounting and adjusting in sealing configuration at present.Former Sealing 11 mostly is bowl-type rubber and makes, and because bearing upper cover 2 is the song that welding or cast structure seal face mostly are cylndrical surface or complexity, the rubber seal 11 of bowl-type is difficult to adjustment when mounted whole curved surface sealing.
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 when fastening pipe joint 6, Sealing 11 cannot be oppressed accurately to produce applicable amount of deformation to reach the effect of sealing.
Summary of the invention
The present invention is exactly for the problems referred to above, provides a kind of structure simple, 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 invention, the present invention adopts following technological scheme, the present invention includes spherical bush, spherical bush is outside equipped with bearing upper cover, spherical bush is provided with pipe joint, bearing upper cover is provided with opening corresponding to pipe joint, it is characterized in that: outside bearing upper cover being positioned at described opening, be fixedly installed the support tube concentric with pipe joint, the end face of support tube is provided with the gland of annular by bolt, be provided with the sealing gasket of annular between gland and the end face of support tube, the endoporus of sealing gasket is with pipe joint interference fit.
As a preferred embodiment of the present invention, described gland inwall is set to inclined-plane corresponding to the edge of sealing gasket.
As another kind of preferred version of the present invention, the upper end in described support tube is provided with bracing ring corresponding to sealing gasket.
Beneficial effect of the present invention: 1, sealing configuration of the present invention achieves and becomes end face seal from former curved surface sealing; Reliability significantly improves.
2, because structure of the present invention is simple, in Installation and adjustment process, the labor intensity of operator is greatly reduced.
3, the sealing gasket of sealing configuration of the present invention is changed conveniently, (existing structure needs could change after pipe joint dismounting).
4, the gasket structure used due to sealing configuration of the present invention is simple, is easy to make, and changes existing Sealing and makes the problem needing special die, reduce cost of production and the maintenance cost of equipment.

Embodiment
The present invention includes spherical bush 1, spherical bush 1 is outside equipped with bearing upper cover 2, spherical bush 1 is provided with pipe joint 6, bearing upper cover 2 is provided with opening 5 corresponding to pipe joint 6, it is characterized in that: outside bearing upper cover 2 being positioned at described opening 5, be fixedly installed the support tube 9 concentric with pipe joint 6, the end face of support tube 9 is provided with the gland 3 of annular by bolt 8, be provided with the sealing gasket 4 of annular between the end face of gland 3 and support tube 9, the endoporus of sealing gasket 4 is with pipe joint 6 interference fit.
As a preferred embodiment of the present invention, described gland 3 inwall is set to inclined-plane 10 corresponding to the edge of sealing gasket 4.
As another kind of preferred version of the present invention, the upper end in described support tube 9 is provided with bracing ring 7 corresponding to sealing gasket 4.By the cooperation on inclined-plane 10 in bracing ring 7 and gland 3, sealing gasket 4 and gland 3 can be made fully to fit, improve sealing effect further.
The present invention by being provided with support tube 9 and bracing ring 7 on bearing upper cover 2, can carrying out machining, obtain good sealing plane, can increase substantially sealing effect on the end face of support tube 9 and bracing ring 7.
Be understandable that, above about specific descriptions of the present invention, the technological scheme described by the embodiment of the present invention is only not limited to for illustration of the present invention, those of ordinary skill in the art is to be understood that, still can modify to the present invention or equivalent replacement, to reach identical technique effect; Needs are used, all within protection scope of the present invention as long as meet.
