Abstract
The utility model discloses a kind of crossed roller bearing, comprise outer ring, several rollers, inner ring and divider, the opposing end surface of described outer ring and inner ring is circumferentially respectively equipped with several restraining grooves, roller is that 90 ° of mutual cross arrangements are in restraining groove, between roller and restraining groove, extruding forms interference fit mutually, and be provided with divider between adjacent rollers, roller is cylindrical roller, its two ends are transition arc, and outer ring is provided with several mounting holes.Can not be there is end thereof contacts phenomenon or the deadlock phenomenon of roller in crossed roller bearing of the present utility model, have high-precision rotary motion and high rigidity, there will not be vibration problem in the course of the work.
Description
Technical field
The utility model relates to technical field of bearings, specifically, relates to a kind of crossed roller bearing.
Background technique
Bearing is in mechanical transmission course, play parts that are fixing and reduction load friction factor.Alternatively, when other parts produce relative movement each other on axle, be used for reducing the fixing parts of friction factor in power transmission process and retainer shaft central position.Bearing is a kind of very important component in contemporary machinery.Its major function is supported mechanical solid of rotation, in order to reduce the mechanical load friction factor of equipment in transmission process.For our device, it is made up of inner ring, outer ring and rolling element, wherein inner ring and rolling element, gap is had between rolling element and outer ring, in use because the gap of bearing, when alternate load effect lower shaft rotates, axle just has the vibration being equivalent to 2 all gaps of bearing, that is the amplitude of axle system equals the bearing play sum of axle two end supports, and bearing gapless driving refers to the gapless bearing (P4 level) of special making or eliminates gap by accurate pretension installation bearing.In fact, when little alternate load effect lower shaft rotates, do not have vibration to produce, but when load is larger, the rolling element of bearing pressurized side will produce distortion, inner ring and axle will move to pressurized side, differ between the rolling element of 180 degree of positions and Internal and external cycle just there will be gap with its position, and now also there will be has gap transmission.
Model utility content
In view of this, the purpose of this utility model is to provide a kind of crossed roller bearing, to solve bearing of the prior art when larger alternate load move under influence, there is gap between rolling element and Internal and external cycle, in working procedure, occur that influence of vibration normally works and the deficiency existed.
The utility model solves the problems of the technologies described above by the following technical programs:
A kind of crossed roller bearing, comprise outer ring, several rollers, inner ring and divider, the opposing end surface of described outer ring and inner ring is circumferentially respectively equipped with several restraining grooves, roller is that 90 ° of mutual cross arrangements are in restraining groove, between roller and restraining groove, extruding forms interference fit mutually, and be provided with divider between adjacent rollers, roller is cylindrical roller, its two ends are transition arc, and outer ring is provided with several mounting holes.
Arc-shaped gaps is provided with around the surface of contact of described roller and restraining groove.
Described restraining groove comprises restraining groove I and restraining groove II, and wherein, restraining groove I is arranged on outer ring, and restraining groove II is arranged on inner ring.
The cross section of described restraining groove I is " V " shape.
The cross section of described restraining groove II is " V " shape.
Packing ring is provided with between described outer ring and inner ring.
The beneficial effects of the utility model are: the utility model is equipped with separation member between the roller of vertical arrangement, prevent the phase mutual friction toppled between roller of roller, so can prevent the increase of rotation torque.End thereof contacts phenomenon or the deadlock phenomenon of roller can not be there is.Further, because inner ring or outer ring are the structures of segmentation, bearing clearance can adjust, and can carry to obtain high-precision rotary motion and high rigidity by applying to give to bearing.Because roller is cross arrangement, only significantly improve rigidity with the load that 1 crossed roller bearing just can bear all directions.Roller and restraining groove are extruded and forms interference fit, making roller just there is certain extruding force when starting working, there will not be gap in the course of the work, efficiently solve the vibration problem occurred in bearing working process.
