Abstract
The utility model relates to an end surface type crossed roller bearing which comprises a shaft ring, a seat ring and a cylindrical rolling body, wherein the shaft ring and the seat ring are axially arranged, the opposite end surfaces of the shaft ring and the seat ring are respectively provided with a V-shaped groove in the circumferential direction, the cylindrical rolling body is arranged between the V-shaped grooves of the shaft ring and the seat ring, and the cylindrical rolling body (2) is arranged in a crossed manner. Thus, under the conditions of the equivalent axial and radial supporting capacities, the utility model can greatly reduce the radial size of the bearing, thereby being widely used for situations in which the radial installation size is limited.
Description
Technical field
The utility model relates to a kind of crossed roller bearing, particularly a kind of end-surface type crossed roller bearing.
Background technique
Existing end-surface type crossed roller bearing is a radial; Generally form by outer ring, inner ring, cylinder rolling element and rolling elements separator; Be processed with V-shaped groove on the internal diameter of outer ring and the external diameter of inner ring; Outer ring and inner ring arranged radially during installation, inner ring is installed in the inside of outer ring, intersects between inner ring and the outer ring to be placed with rolling element.
Mainly there is the defective of two aspects in existing end-surface type crossed roller bearing: the one, and radial dimension is very big, needs bigger radially installing space.The 2nd, need processing rolling element mounting hole, complex process and reduction bearing capacity.
This shows that above-mentioned existing end-surface type crossed roller bearing obviously still has inconvenience and defective, and demands urgently further improving in structure and use.In order to solve the problem of above-mentioned existence; Relevant manufacturer there's no one who doesn't or isn't seeks solution painstakingly; But do not see always that for a long time suitable design is developed completion, and common product does not have appropriate structure to address the above problem, this obviously is the problem that the anxious desire of relevant dealer solves.Therefore how to found a kind of end-surface type crossed roller bearing, real one of the current important research and development problem that belongs to, also becoming the current industry utmost point needs improved target.
Summary of the invention
The purpose of the utility model is, a kind of end-surface type crossed roller bearing is provided, and having under the situation axially equal and radially bearing capacity, the radial dimension of bearing is dwindled greatly, is widely used in radially installation dimension occasions with limited.
The purpose of the utility model and to solve its technical problem be that technological scheme below adopting realizes.A kind of end-surface type crossed roller bearing according to the utility model proposition; Comprise blowout patche, seat ring and cylinder rolling element; Blowout patche and seat ring are axially-aligned; Along the circumferential direction be respectively arranged with V-shaped groove on the opposing end surface of blowout patche and seat ring, the cylinder rolling element is arranged at blowout patche) and seat ring) V-shaped groove between, and the cylinder rolling element) be cross arrangement.
The purpose of the utility model and solve its technical problem and can also adopt following technical measures to come further to realize.
Aforesaid end-surface type crossed roller bearing wherein is respectively arranged with on the apparent surface of blowout patche and seat ring and is connected screw.
Aforesaid end-surface type crossed roller bearing wherein is provided with rolling elements separator between the cylinder rolling element.
The utility model compared with prior art has tangible advantage and beneficial effect.By technique scheme; The utility model end-surface type crossed roller bearing has advantage and beneficial effect at least: because the utility model adopts the axially-aligned mode with blowout patche, seat ring and cylinder rolling element, so can significantly reduce the radial dimension of end-surface type crossed roller bearing.And the cylinder rolling element is easy for installation, need not to process the rolling element mounting hole.
Above-mentioned explanation only is the general introduction of the utility model technological scheme; In order more to know the technological means of understanding the utility model; And can implement according to the content of specification, and for let the above-mentioned of the utility model with other purposes, feature and advantage can be more obviously understandable, below special act preferred embodiment; And conjunction with figs., specify as follows.
Description of drawings
Fig. 1 is the sectional drawing of a preferred embodiment of the utility model end-surface type crossed roller bearing.
Fig. 2 is the plan view of a preferred embodiment of the utility model end-surface type crossed roller bearing.
Embodiment
For further setting forth the utility model is to reach technological means and the effect that predetermined goal of the invention is taked; Below in conjunction with accompanying drawing and preferred embodiment; To its embodiment of end-surface type crossed roller bearing, structure, characteristic and the effect thereof that proposes according to the utility model, specify as after.
See also illustrated in figures 1 and 2ly, Fig. 1 is the sectional drawing of a preferred embodiment of the utility model end-surface type crossed roller bearing, and Fig. 2 is the plan view of a preferred embodiment of the utility model end-surface type crossed roller bearing.The end-surface type crossed roller bearing comprises blowout patche 1, seat ring 2 and cylinder rolling element 3; In the utility model; Blowout patche 1 is axially-aligned with seat ring 2; Along the circumferential direction be respectively arranged with V-shaped groove on the opposing end surface of blowout patche 1 and seat ring 2, cylinder rolling element (3) is arranged between the V-shaped groove of blowout patche 1 and seat ring 2, and cylinder rolling element (2) is cross arrangement.
In the utility model, also can be respectively arranged with on the apparent surface of blowout patche (1) and seat ring (2) and be connected screw, also the connection screw can be set.
In the utility model, improve limit speed if desired, can also between cylinder rolling element 3, be provided with rolling elements separator 4.
Above-mentioned end-surface type crossed roller bearing; Be that blowout patche, seat ring and cylinder rolling element are adopted the axially-aligned mode; So can significantly reduce the radial dimension of end-surface type crossed roller bearing; Having under the situation axially equal and radially bearing capacity, the radial dimension of bearing is dwindled greatly, be widely used in radially installation dimension occasions with limited.In addition, the cylinder rolling element is easy for installation, need not to process the rolling element mounting hole.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Though the utility model discloses as above with preferred embodiment, yet be not that any professional and technical personnel of being familiar with is not in breaking away from the utility model technological scheme scope in order to qualification the utility model; When the technology contents of above-mentioned announcement capable of using is made a little change or is modified to the equivalent embodiment of equivalent variations; In every case be the content that does not break away from the utility model technological scheme, to any simple modification, equivalent variations and modification that above embodiment did, all still belong in the scope of the utility model technological scheme according to the technical spirit of the utility model.
