Abstract
Rolling bearing units for architecture advances, comprise the bearing support of bearing with spherical outside surface and Flange-shaped Parts, and the center of bearing support forms the through hole run through, and the bearing support of through hole surrounding forms some tapped holes; Madial wall in the middle part of described bearing support through hole forms the groove of spheric, bearing with spherical outside surface is embedded in the groove of bearing support, the through-hole wall of groove side is equipped with limited location snap ring, the through hole madial wall at limited location snap ring place forms the oil groove of a pair connection shaft bearing one side end face and groove, the bearing support end face of oil groove surrounding forms the seal ring resettlement groove of annular, bearing support other end forms the seal groove of annular, the degree of depth of seal groove equals the distance of seal groove place bearing support end face to groove.It uses at bearing support both ends of the surface forming seal slot fit seal ring on the basis of original bearing support, thus meets installation requirements, simultaneously corresponding in bearing support shaping oil groove to bearing lubrication; And the slewing area that snap ring limits its bearing is set.
Description
Technical field:
The utility model relates to the technical field of bearing, more specifically to a kind of rolling bearing units of architecture advances.
Background technique:
There is the cardan shaft bearing of some flange shapes in existing market, its by the bolt hole on bearing block flange or via hole and equipment or equipment mechanism in mating connection; But the both ends of the surface of existing bearing support are all generally planes, guarantee cannot be carried out when ensureing that the attachment face of mechanism matches with other equipment or device seal, some are had to equipment or the device of requirement sealing effect, the cardan shaft bearing of the flange shape that market is common cannot meet its installation requirement.
Model utility content:
The purpose of this utility model is exactly the deficiency for prior art, and provides a kind of rolling bearing units of architecture advances, and it is used by forming seal slot fit seal ring on the two ends of bearing support, meets the requirement that sealing is installed.。
Technology solution of the present utility model is as follows:
Rolling bearing units for architecture advances, comprise the bearing support of bearing with spherical outside surface and Flange-shaped Parts, and the center of bearing support forms the through hole run through, and the bearing support of through hole surrounding forms some tapped holes; Madial wall in the middle part of described bearing support through hole forms the groove of spheric, bearing with spherical outside surface is embedded in the groove of bearing support, the through-hole wall of groove side is equipped with limited location snap ring, the through hole madial wall at limited location snap ring place forms the oil groove of a pair connection shaft bearing one side end face and groove, the bearing support end face of oil groove surrounding forms the seal ring resettlement groove of annular, bearing support other end forms the seal groove of annular, the degree of depth of seal groove equals the distance of seal groove place bearing support end face to groove.
Described bearing with spherical outside surface is made up of the outer ring of inner ring, outer spherical surface, retainer, sealing cover and ball, ball and retainer are clamped between outer ring and inner ring, sealing cover is provided with between outer ring and inner ring, sealing cover all adopts the sealing cover of many lips, and bearing with spherical outside surface is provided with two sealing covers near bearing support seal groove side.
The beneficial effects of the utility model are:
1, it uses at bearing support both ends of the surface forming seal slot fit seal ring on the basis of original bearing support, thus meets installation requirements, simultaneously corresponding in bearing support shaping oil groove to bearing lubrication; And the slewing area that snap ring limits its bearing is set.
2, it forms groove at bearing support one end face, facilitates the installation of bearing and bearing support.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is sectional structure schematic diagram of the present utility model.
In figure: 1, bearing with spherical outside surface; 2, bearing support; 3, limited location snap ring; 21, through hole; 22, groove; 23, seal groove; 24, oil groove; 25, seal ring resettlement groove; 26, tapped hole.
Embodiment:
Embodiment: see shown in Fig. 1,2, a kind of rolling bearing units of architecture advances, comprises the bearing support 2 of bearing with spherical outside surface 1 and Flange-shaped Parts, and the center of bearing support 2 forms the through hole 21 run through, and the bearing support 2 of through hole 21 surrounding forms some tapped holes 26; Madial wall in the middle part of described bearing support 2 through hole 21 forms the groove 22 of spheric, bearing with spherical outside surface 1 is embedded in the groove 22 of bearing support 2, through hole 21 inwall of groove 22 side is equipped with limited location snap ring 3, through hole 21 madial wall at limited location snap ring 3 place forms the oil groove 24 of a pair connection shaft bearing 2 one side end face and groove 22, bearing support 2 end face of oil groove 24 surrounding forms the seal ring resettlement groove 25 of annular, bearing support 2 other end forms the seal groove 23 of annular, the degree of depth of seal groove 23 equals the distance of seal groove 23 place bearing support 2 end face to groove 22.
Described bearing with spherical outside surface 1 is made up of the outer ring of inner ring, outer spherical surface, retainer, sealing cover and ball, ball and retainer are clamped between outer ring and inner ring, sealing cover is provided with between outer ring and inner ring, sealing cover all adopts the sealing cover of many lips, and bearing with spherical outside surface 1 is provided with two sealing covers near bearing support 2 seal groove 23 side.
Working principle: this bearing support improves on the original basis; By using at bearing support both ends of the surface forming seal groove 23 and seal ring resettlement groove 25 fitted seal circle, thus meet the demand of sealing installation, corresponding shaping oil groove 24 pairs of bearing lubrication in bearing support simultaneously; And the slewing area that limited location snap ring 3 limits its bearing is set; When also having its seal groove 23 can make bearing with spherical outside surface 1 embedded axle bearing 2, the outer side wall of its bearing support 2 through hole 21 end facilitates resiliently deformable to expand, and facilitates the embedding of bearing with spherical outside surface 1.
