Description
Technical field
The utility model relates to a kind of hermetically sealed bearing seat with spherical outside surface, belongs to bearing assemble technical field.
Background technique
At present, the outer spherical surface rolling bearing units assembly of prior art is used on the equipment such as farm machinery, mining machinery, conveyor belt, bearing directly contacts with external environment, failure conditions is used to analyze from bearing in the past, major part is because the Sealing of bearing can not stop that extraneous dirt invades Bearing inner, cause worn steel ball in bearing serious, the working life of bearing is reduced greatly.In addition, also have on bearing support and be with sealing configuration, but be all sealing configuration and the plastic end cover of some steel plate frames, rigidity is poor, and sealing effect is bad.
Summary of the invention
Technical problem to be solved in the utility model is the defect overcoming prior art, provides a kind of hermetically sealed bearing seat with spherical outside surface, which increases its sealing effect, improve the working life of bearing, and structure is simple.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of hermetically sealed bearing seat with spherical outside surface, it comprises sealing pedestal and end cover, sealing pedestal is fixedly connected with by lock bolt with end cover, and seal between pedestal and end cover and surround bearing installation cavity, the non-tight end cap mounting end of described sealing pedestal is provided with rotary shaft hole, and this non-tight end cap mounting end has seal groove in the periphery of rotary shaft hole, and be embedded with in seal groove can with the felt seal part of the running shaft interference fit penetrated in rotary shaft hole.
Further for the ease of bearing assemble in bearing installation cavity, described sealing pedestal is provided with the bearing assemble mouth of direction to running shaft arranged outside, and this bearing assemble mouth is positioned on bearing installation cavity.
Further, described end cover is made up of gray cast iron.
After have employed technique scheme, first assemble hair and glue Sealing in seal groove, again bearing with spherical outside surface is assembled in bearing installation cavity, again running shaft being penetrated rotary shaft hole and gluing Sealing by hair installs in bearing installation cavity, with the lock screw locking rotating rotating shaft on bearing with spherical outside surface, then with lock bolt, end cover is assembled on sealing pedestal, makes whole product be in complete sealing state, make product play good seal action, the working life of bearing products is improved greatly.
Accompanying drawing explanation
Fig. 1 is the scheme of installation of hermetically sealed bearing seat with spherical outside surface of the present utility model;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is the structural representation of sealing pedestal of the present utility model.
Embodiment
In order to make content of the present utility model more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail.
As shown in Figures 1 to 3, a kind of hermetically sealed bearing seat with spherical outside surface, it comprises sealing pedestal 1 and end cover 2, sealing pedestal 1 is fixedly connected with by lock bolt 3 with end cover 2, and seal between pedestal 1 and end cover 2 and surround bearing installation cavity 12, the non-tight end cap mounting end of sealing pedestal 1 is provided with rotary shaft hole 1-1, and this non-tight end cap mounting end has seal groove 1-2 in the periphery of rotary shaft hole 1-1, and be embedded with in seal groove 1-2 can with the felt seal part 4 of running shaft 6 interference fit penetrated in rotary shaft hole 1-1.
For the ease of bearing assemble in bearing installation cavity 12, as shown in Figure 3, sealing pedestal 1 is provided with the bearing assemble mouth 1-3 of direction to running shaft 6 arranged outside, and this bearing assemble mouth 1-3 is positioned on bearing installation cavity 12.
End cover 2 is made up of gray cast iron, but is not limited thereto.
Working principle of the present utility model is as follows:
First assembling hair glues in Sealing 4 to seal groove 1-2, again bearing with spherical outside surface 5 is assembled in bearing installation cavity 12, again running shaft 6 being penetrated rotary shaft hole 1-1 and being glued Sealing 4 by hair installs in bearing installation cavity 12, with the lock screw locking rotating rotating shaft 6 on bearing with spherical outside surface 5, with lock bolt, end cover 2 is assembled on sealing pedestal 1 again, make whole product be in complete sealing state, make product play good seal action, the working life of bearing products is improved greatly.
Above-described specific embodiment; technical problem, technological scheme and beneficial effect that the utility model solves are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
