Description
Technical field
The utility model relates to parts of bearings field, especially a kind of cylindrical roller of bearing.
Background technique
The element that load is born when roller is bearing operation, is part most weak in roller bearing, its manufacturing quality
Have a great impact to bearing working performance (such as running accuracy, vibration, noise and flexibility), is to influence bearing service life
Principal element.
The side profile bus section, busbar section and end profile bus section, busbar section of existing roller, end profile bus section, busbar section and internal diameter profile are female
Line segment is often the connection of straight line chamfering, and the bearing after molding assembly is easy to cause bearing damage due to the problems in stress collection.
Summary of the invention
The purpose of this utility model is to provide a kind of cylindrical rollers of bearing, to meet stress concentration at roller chamfer
Problem.
To realize above-mentioned technical purpose and the technique effect, the utility model discloses a kind of rollings of the cylinder of bearing
Son includes roller ontology, and the roller ontology is the cylindrical body for having certain internal diameter hole, the roller ontology
Bus includes side profile bus section, busbar section, end profile bus section, busbar section and internal diameter profile bus section, busbar section, the side profile bus section, busbar section and
End profile bus section, busbar section passes through two sections of outside chamfering bus section, busbar section connections, the internal diameter profile bus section, busbar section and end profile bus section, busbar section
It is connected by two sections of inner side chamfering bus section, busbar sections, the bus of the roller ontology rotates to form roller ontology around roller axis.
Further, the outside chamfering bus section, busbar section includes the first oblique line section, the second oblique line section and outside arc segment, institute
The first oblique line section, the second oblique line section stated are connect with side profile bus section, busbar section, end profile bus section, busbar section respectively, the lateral arcs
Line segment and the first oblique line section, the tangent connection of the second oblique line section.
Further, the first oblique line section and side profile bus section, busbar section end, the second oblique line section and end profile bus
Angle formed by section is 45 degree.
Further, the inner side chamfering bus section, busbar section is one section of inside arc segment, the inside arc segment and internal diameter
The tangent connection of profile bus section, busbar section, end profile bus section, busbar section.
The utility model has the following beneficial effects:
1. the utility model solves cylinder by three sections of oblique line sections of outside surface chamfer, the mode of medial surface chamfering circular arc connection
Roller is assembled into bearing in use, the problems in roller stress excessively collects.
2. the connection of the utility model inside and outside two chamfering line segments through reasonable settings, to keep the stress of roller equal
It is even, improve the service life of entire bearing.

Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.
As shown in the picture, the utility model discloses a kind of cylindrical rollers of bearing, include roller ontology 1, described
Roller ontology 1 is the cylindrical body for having certain internal diameter hole, and the bus of the roller ontology 1 includes side profile bus section, busbar section
3, end profile bus section, busbar section 2 and internal diameter profile bus section, busbar section 6, the side profile bus section, busbar section 3 and end profile bus section, busbar section 2 pass through
Two sections of outside chamfering bus section, busbar sections 4 connect, and the internal diameter profile bus section, busbar section 6 is fallen with end profile bus section, busbar section 2 by two sections of insides
Angle bus section, busbar section 5 connects, and the bus section, busbar section of the roller ontology 1 rotates to form roller ontology around roller axis.
The outside chamfering bus section, busbar section 4 includes the first oblique line section 7, the second oblique line section 9 and outside arc segment 8, described
First oblique line section 7, the second oblique line section 9 are connect with side profile bus section, busbar section 3, end profile bus section, busbar section 2 respectively, the lateral arcs
Line segment 8 and the first oblique line section 7, the tangent connection of the second oblique line section 9.
The described first oblique line section 7 and side profile bus section, busbar section end 3, the second oblique line section 9 and 2 institute of end profile bus section, busbar section at
Angle be 45 degree.
The inner side chamfering bus section, busbar section 5 is one section of inside arc segment 10, the inside arc segment 10 and internal diameter profile
The tangent connection of bus section, busbar section 6, end profile bus section, busbar section 2.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in
Change or replacement, should be covered within the scope of the utility model.
