Abstract
This utility model relates to a kind of cylindrical roller thrust bearing, include the inner ring being coaxially disposed, outer ring, described outer ring is provided with outer raceway, inner ring is provided with interior raceway, it is provided with retainer between described outer raceway and interior raceway, retainer is provided with some cylindrical rollers, the sidewall of roller and outer raceway, interior raceway is conflicted, it is characterized in that: described outer raceway, interior raceway is taper surface, outer raceway is 45 degree with the angle of outer ring central axis, interior raceway is 45 degree with the angle of inner ring central axis, the central axis of roller is also 45 degree with the angle of outer ring central axis.Using technique scheme, this utility model provides a kind of cylindrical roller thrust bearing, can bear bigger axial force and bigger radial force simultaneously, is suitable to middling speed and rotates.
Description
Technical field
This utility model relates to field of bearings, particularly to a kind of cylindrical roller thrust bearing.
Background technology
The cylindrical roller thrust bearing of standard design belongs to divergence type bearing, can only bear the axial load that one direction is bigger,
But radial load can not be born, its be merely able to limit axle (or shell) direction axial displacement, can be used as unidirectional axially
Location, but can not radially position；And, the cylindrical roller thrust bearing of standard design, during roller rolls, due to roller two end line
Speed is different, makes roller be inevitably generated slip on lasso raceway, and therefore, it is generally only applicable to low-speed running field
Close.
Summary of the invention
The purpose of this utility model: in order to overcome the defect of prior art, this utility model provides a kind of thrust cylindrical
Roller bearing, can bear bigger axial force and bigger radial force simultaneously, is suitable to middling speed and rotates.
The technical solution of the utility model: a kind of cylindrical roller thrust bearing, includes inner ring, the outer ring being coaxially disposed,
Described outer ring is provided with outer raceway, and inner ring is provided with interior raceway, is provided with retainer between described outer raceway and interior raceway, protects
Holding frame and be provided with some cylindrical rollers, the sidewall of roller and outer raceway, interior raceway are conflicted, it is characterised in that: described outer raceway,
Interior raceway is taper surface, and outer raceway is 45 degree with the angle of outer ring central axis, interior raceway and the angle of inner ring central axis
Being 45 degree, the central axis of roller is also 45 degree with the angle of outer ring central axis.
Use technique scheme so that bearing can bear bigger axial force and bigger radial force simultaneously；And, rolling
The linear velocity difference at sub-two ends is less than common cylindrical roller thrust bearing so that it is less than normal that roller produces slip on raceway,
Rotate so that it can be adapted to middling speed.
Further setting of the present utility model: the two ends of described outer raceway all extend to outside outer ring, described interior raceway
Two ends all extend to outside inner ring.
Use above-mentioned further setting, external raceway, interior raceway so can be facilitated to be processed, also allow for guarantor simultaneously
Hold the installation of frame, roller.
Further setting of the present utility model: described retainer is that plastics are made.
Use and above-mentioned further arrange, the quality of bearing can be alleviated, reduce noise during bearing operation.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model specific embodiment.
Detailed description of the invention
As it is shown in figure 1, a kind of cylindrical roller thrust bearing, include inner ring 1, the outer ring 2 being coaxially disposed, described outer ring
2 are provided with outer raceway 21, and inner ring 1 is provided with interior raceway 11, is provided with retainer 3 between described outer raceway 21 and interior raceway 11,
Retainer 3 is provided with some cylindrical rollers 4, and the sidewall of roller 4 is conflicted with outer raceway 21, interior raceway 11, described outer raceway 21,
Interior raceway 11 is taper surface, and outer raceway 21 is 45 degree with the angle of outer ring 2 central axis, interior raceway 11 and inner ring 1 central shaft
The angle of line is 45 degree, and the central axis of roller 4 is also 45 degree with the angle of outer ring 2 central axis.So make the bearing can be with
Time bear bigger axial force and bigger radial force；And, the linear velocity difference at roller 4 two ends is than common thrust cylindrical rolling
Sub-bearing is little so that it is less than normal that roller 4 produces slip on raceway, rotates so that it can be adapted to middling speed.
In this utility model specific embodiment, the two ends of described outer raceway 21 all extend to outside outer ring 2, described interior rolling
The two ends in road 11 all extend to outside inner ring 1.External raceway 21, interior raceway 11 so can be facilitated to be processed, also allow for simultaneously
To retainer 3, the installation of roller 4.
In this utility model specific embodiment, described retainer 3 is made for plastics.So can alleviate the matter of bearing
Amount, reduces noise during bearing operation.
