Description
Technical field
The utility model relates to a kind of selfaligning roller bearing, is the selfaligning roller bearing that the outer ring be used on speed reducer carries the gear teeth specifically.
Background technique
All know in machinery industry, selfaligning roller bearing has two row rollers, substantial radial load, also can bear the thrust load of either direction simultaneously, there is higher radial capacity, work under being specially adapted to heavy duty or oscillating load, but pure thrust load can not be born.
At present, the selfaligning roller bearing used in industry comprises outer ring and inner ring, outer ring sleeve is in the outside of inner ring, the retainer of annular is had between outer ring and inner ring, the both sides of retainer are evenly equipped with pocket hole along its circumference, all have the roller in waist drum shape in pocket hole, all coordinate in rolling between roller with pocket hole, have movable spacer ring between the roller of retainer side and the roller of opposite side, the position in the internal surface of described outer ring, the outer surface corresponding retainer two side pocket hole of inner ring is all in inner ball surface shape.When this selfaligning roller bearing uses on speed reducer, keeping consistency to make outer ring and small planetary gear rotate, needing first small planetary gear to be emptied.Small planetary gear is being enclosed within the outer ring of bearing.Then, with circlip, bearing is fixed on small planetary gear, finally again small planetary gear is installed to together with bearing in the cabinet of speed reducer and meshes together with mafor planet gear.Whole installation process is more complicated, and there will be the larger situation of Concentricity tolerance when being fixed on small planetary gear by bearing, thus reduces installation precision, shortens the working life of speed reducer.
Model utility content
The technical problems to be solved in the utility model is to provide the selfaligning roller bearing that a kind of outer ring carries the gear teeth, and this selfaligning roller bearing uses in speed reducer, and installation process is comparatively simple, installation efficiency is higher, and installation precision is higher, can working life of prolonged deceleration machine.
For solving the problem, provide following technological scheme:
Outer ring of the present utility model carries the selfaligning roller bearing of the gear teeth, comprise outer ring and inner ring, outer ring sleeve is in the outside of inner ring, the retainer of annular is had between outer ring and inner ring, the both sides of retainer are evenly equipped with pocket hole along its circumference, all have the roller in waist drum shape in pocket hole, all coordinate in rolling between roller with pocket hole, have movable spacer ring between the roller of retainer side and the roller of opposite side, the position of the internal surface of described outer ring, the outer surface corresponding retainer both sides roller of inner ring is all in inner ball surface shape.Be characterized in that the outer surface of described outer ring is circumferentially evenly equipped with the gear teeth, axial arranged all along outer ring of the gear teeth, and the gear teeth and outer ring are all in integrative-structure.
The further improvement of the utility model scheme width that is described outer ring is greater than to the width of inner ring, outer ring both ends of the surface are positioned at the outside of inner ring both ends of the surface respectively.The advantage of such improvement to improve the precision of aligning.
Take above scheme, have the following advantages:
The selfaligning roller bearing carrying the gear teeth due to outer ring of the present utility model comprises outer ring, inner ring, retainer and roller, and the outer surface of outer ring is circumferentially evenly equipped with the gear teeth, axial arranged all along outer ring of the gear teeth, and the gear teeth and outer ring are all in integrative-structure.So, can directly attach it in the cabinet of speed reducer, meshed together by the gear teeth on outer ring and mafor planet gear, thus greatly reduce the complexity of installation, improve installation efficiency, and the situation that the Concentricity tolerance occurred when bearing can be avoided to be fixed on small planetary gear is larger, improve installation precision, extend the working life of speed reducer.
Accompanying drawing explanation
Fig. 1 is the structural representation that outer ring of the present utility model carries the selfaligning roller bearing of the gear teeth;
Fig. 2 is that the A-A of Fig. 1 is to sectional view.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, the selfaligning roller bearing that outer ring of the present utility model carries the gear teeth comprises outer ring 3 and inner ring 1, and outer ring 3 is enclosed within the outside of inner ring 1, and the width of outer ring 3 is greater than the width of inner ring 1, and outer ring 3 both ends of the surface are positioned at the outside of inner ring 1 both ends of the surface respectively.The retainer 6 of annular is had between outer ring 3 and inner ring 1, the both sides of retainer 6 are evenly equipped with pocket hole 5 along its circumference, the roller 2 in waist drum shape is all had in pocket hole 5, all coordinate in rolling between roller 2 with pocket hole 5, have movable spacer ring 7 between the roller 2 of retainer 6 side and the roller 2 of opposite side, the position of the internal surface of described outer ring 3, the outer surface corresponding retainer 6 both sides roller 2 of inner ring 1 is all in inner ball surface shape.The outer surface of described outer ring 3 is circumferentially evenly equipped with the gear teeth 4, axial arranged all along outer ring 3 of the gear teeth 4, and the gear teeth 4 and outer ring 3 are all in integrative-structure, and outer ring 3 and the gear teeth 4 are made by carbonized Gear Steel.
During use, this selfaligning roller bearing is directly installed in speed reducer, is meshed together with mafor planet gear by the gear teeth 4 on outer ring 3.Thus greatly reduce the complexity of installation, improve installation efficiency, and the situation that the Concentricity tolerance occurred when bearing can be avoided to be fixed on small planetary gear is larger, improve installation precision, extend the working life of speed reducer.
