Description
Technical field
The utility model relates to a kind of bearing, particularly relates to the crossed roller bearing of a kind of circular cone rolling element and steel ball rolling body cross-distribution.
Background technique
At present crossed roller bearing is that cylinder or circular cone rolling element are 90 ° of mutual square crossings and are arranged on the roller surface of V shape groove, and retainer or spacing block are housed between rolling element.This kind of bearing can bear radial and axial multidirectional load, affected the rotational speed of bearing.In the mechanical part that bears multiaxis loading and need to run up, still adopt pairing to use less angular contact ball bearing or the four-point contact ball of bearing capacity at present.Therefore be difficult to bear both sides twocouese axial load and radial load, and affect bearing working life.
The model utility content
The purpose of this utility model, be to provide the crossed roller bearing of a kind of circular cone rolling element and steel ball rolling body cross-distribution, and this bearing can bear its both sides twocouese axial force and larger radial load, and bearing has higher rotational speed simultaneously.
The purpose of this utility model can adopt following technological scheme to realize:
The crossed roller bearing of a kind of circular cone and steel ball rolling body cross-distribution, by cylindrical, inner ring and be installed in outer ring and inner ring between a row Combined roller in the raceway that forms form, it is characterized in that:
One, bearing outer ring: this bearing outer ring cross section is reversed V-shape, and the reversed V-shape raceway is on one side for being greater than miter angle plane of inclination raceway, and this raceway is as circular cone rolling element raceway.Because the raceway wrapping angle is larger, so can bear bearing one side larger axis to load and radial load.Reversed V-shape raceway another side and front raceway angle are less than 90 degree, and the middle part, plane of inclination has the spherical arc raceway.Be positioned at the arc raceway middle part with the steel ball point of contact.With about 45 degree of axis contact angle, similar to angular contact ball bearing, inclined-plane, arc raceway both sides rib can do the large end ball of circular cone rolling element basal plane rib simultaneously and the steel ball rib is used.Therefore this bearing can bear axial load and the radial load that other direction is less, has higher rotational speed simultaneously.
Two, bearing inner race: this bearing inner race is two style structure, and after two inner ring combinations, cross section is V-shaped.The V-arrangement raceway on one side has the spherical arc raceway in the middle part, inclined-plane, with the steel ball point of contact, is positioned at the arc raceway middle part, with about 45 degree of axis contact angle, similar with angular contact ball bearing.Inclined-plane, arc raceway both sides rib can do circular cone rolling element small end face rib simultaneously and steel ball rolling body rib is used, and this rib and circular cone rolling element small end face have certain interval, and in the bearing operation process, this rib does not bear load.V-arrangement raceway another side and front raceway angle are less than 90 degree, and this raceway is used as circular cone rolling element raceway.The double-body bike bearing inner race is convenient to bearing assemble, assembles rear inner ring and outer ring raceway, jointly forms raceway and the rib of the inner circular cone of bearing and steel ball rolling body.Owing to can taking full advantage of the lasso raceway, therefore with the bearing of same volume general type, compare, more can bear larger load, there is higher rotating speed simultaneously.Due to reasons in structure, between inner ring external diameter and outer ring internal diameter, very little gap is arranged after bearing assemble, so sealing effect is better in addition.
Three, bearing roller and spacing block: this bearing roller is the structural type that circular cone rolling element and steel ball rolling body are interspersed.Use the isolation of nylon spacing block between rolling element, prevent from colliding between rolling element.Rolling element cross arrangement and bearing ring have formed the crossed roller bearing of circular cone and steel ball rolling body cross-distribution jointly.Its structural similarity is in angular contact ball bearing and tapered roller bearing, can bearing radial force and twocouese axial force, and there are characteristics and the strong characteristics of tapered roller bearing bearing capacity of ball bearing higher rotation speed.Can in the mechanical part that bears multiaxis loading and need to run up, use.
The beneficial effects of the utility model are: crossed roller bearing described in the utility model, can bear bearing both sides twocouese axial load and radial load, and bearing has higher rotational speed simultaneously.The inner steel ball of bearing is 45 degree angles with lasso raceway point of contact line and axis, and structural similarity is in angular contact ball bearing, can bearing radial force and one direction axial force, there are the characteristics of ball bearing higher rotation speed; Circular cone rolling element and lasso form the tapered roller bearing with larger wrapping angle, and the circular cone rolling element utilizes the steel ball rib, does the rib of circular cone rolling element ball basal plane and small end face.Its energy bearing radial force and other direction axial force, and have the advantages that the tapered roller bearing bearing capacity is strong.Therefore, a set of bearing just can bear the load of all directions, compares with traditional model and has higher rotating speed and load, can in the mechanical part that bears multiaxis loading and need to run up, use, and for example on rotor shaft, uses.
