Abstract
A kind of bearing roller, belong to parts of bearings technical field.The utility model includes roller body, the bus of roller body includes arc-shaped profile bus section, busbar section and is connected to two sections of chamfering bus section, busbar sections at arc-shaped profile bus section, busbar section both ends, two sections of chamfering bus section, busbar sections include three sections, the oblique line section that is respectively connected with arc-shaped profile bus section, busbar section, the second oblique line section being connected with the contrate wheel profile of roller body and with oblique line section, the arc of the tangent connection of the second oblique line section, the cylindrical rolling surface to form the roller body is rotated around roller axis by the bus.The chamfering bus section, busbar section of roller body bus is set to three sections by the utility model, pass through the setting of three sections of the line segment, so that the problem of angle of protrusion is not present at roller chamfer, it is round and smooth with cylindrical rolling surface and roller end face transition smooth-going at whole chamfering, the problem of so as to substantially reduce stress concentration at roller chamfer, so that whole roller uniform force, the service life of whole bearing is improved.
Description
Technical field
The utility model belongs to parts of bearings technical field, especially with a kind of bearing roller.
Background technology
The bus of existing self-aligning bearing roller and cylindrical roller 1（It is three-dimensional that the circle to be formed is rotated with axis by the line segment
Structure）Arc-shaped profile bus section, busbar section 2 and chamfering bus section, busbar section 4 are generally included, rotates to form rolling around roller axis by the bus
The cylindrical rolling surface of son, as shown in figure 1, chamfering bus section, busbar section 4 is arranged on the junction of roller outer rim rolling surface 5 and roller end face 3,
The existing generally use straight line chamfering of chamfering bus section, busbar section 4 or circular arc chamfering processing, place after straight line chamfered easily with
There is angle in roller end face and roller outer rim rolling surface, therefore the problem of stress concentration be present, the bearing after molding assembly due to
The problem of stress concentration, easily causes bearing damage；The mode of circular arc chamfering processing is to first pass through the processing side of turning and grinding
Formula, but also can have angle with roller end face and roller outer rim rolling surface at the circular arc chamfering after grinding, there is also should
The problem of power is concentrated.
Utility model content
For drawbacks described above existing for above-mentioned background technology, the utility model aim to provide a kind of roller by stress uniformly and
Bearing roller structure rational in infrastructure.
Therefore, the utility model uses following technical scheme：A kind of bearing roller, including roller body, it is characterized in that, institute
The bus for the roller body stated includes arc-shaped profile bus section, busbar section and is connected to two sections of arc-shaped profile bus section, busbar section both ends
Chamfering bus section, busbar section, two sections of chamfering bus section, busbar sections are including three sections, the oblique line section being respectively connected with arc-shaped profile bus section, busbar section and rolling
Sub- body contrate wheel profile connection the second oblique line section and with oblique line section, the arc of the tangent connection of the second oblique line section, lead to
Cross the bus and rotate the cylindrical rolling surface to form the roller body around roller axis.
As the supplement to above-mentioned technical proposal and perfect, the utility model also includes following technical characteristic.
The angle in the perpendicular face in the end face of oblique line section and roller body and the second oblique line section and described roller body
The angle of end face is acute angle.
The angle in the perpendicular face in the end face of oblique line section and roller body and the second oblique line section and described roller body
The angle of end face is respectively less than 22 degree.
It can reach following beneficial effect using the utility model：The utility model is by the chamfering bus of roller body bus
Section is set to three sections, by the setting of three sections of the line segment, so that the problem of angle of protrusion is not present at roller chamfer, entirely
It is round and smooth with cylindrical rolling surface and roller end face transition smooth-going at chamfering, so as to substantially reduce asking for stress concentration at roller chamfer
Topic, so that whole roller uniform force, improve the service life of whole bearing.
Brief description of the drawings
Fig. 1 is the roller structure schematic diagram of prior art.
Fig. 2 is the connection diagram of chamfering bus section, busbar section of the present utility model.
Embodiment
Specific embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.
As shown in Fig. 2 the utility model includes roller body, the bus of roller body includes arc-shaped profile bus section, busbar section 2
With two sections of chamfering bus section, busbar sections for being connected to the both ends of arc-shaped profile bus section, busbar section 2, two sections of chamfering bus section, busbar sections 4 include three sections,
The oblique line section 7 being respectively connected with arc-shaped profile bus section, busbar section 2, the second oblique line being connected with the contrate wheel profile 6 of roller body
Section 8 and with oblique line section 7, the arc 9 of the tangent connection of the second oblique line section 8, rotate to be formed around roller axis by the bus
The cylindrical rolling surface 5 of the roller body.
Preferably, the angle in the perpendicular face in the end face of oblique line section 7 and roller body and the second oblique line section 8 and roller body
The angle of end face be acute angle.
It is further preferred that the angle in the perpendicular face in the end face of oblique line section 7 and roller body and the second oblique line section 8 and rolling
The angle of the end face of sub- body is respectively less than 22 degree, and 15 degree are preferably used as the present embodiment.
The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within claimed the scope of the utility model.The utility model
Claimed scope is by appended claims and its equivalent thereof.
