Description
Technical field
The utility model relates to a kind of thrust-bearing, particularly relates to a kind of inner ring integrated multiple row roller thrust bearing.
Background technique
Existing thrust-bearing has two kinds: a kind of is angular contact ball bearing group, it is made up of multilayer, every one deck is generally made up of outer ring, inner ring and steel ball, outer ring and inner ring arranged radially, between outer ring and inner ring raceway, form peach type raceway groove, steel ball is arranged at peach type raceway groove inner circumference, and contacting of steel ball and raceway groove is some contact.Another kind is cylindrical roller thrust bearing, comprises seat ring, blowout patche and cylinder rolling element, seat ring and blowout patche axially-aligned, and cylinder rolling element is arranged on the roller surface of seat ring and blowout patche.
Mainly there is following defect in existing thrust-bearing:
1. existing angular contact ball bearing group and existing cylindrical roller thrust bearing mainly bear axial load, can not bear radial load and tilting moment.
2. when existing angular contact ball bearing group is worked, bear dynamic axial load, due to contacting as some contact of steel ball and raceway groove, area of contact is little, and contact stress is large, and steel ball and raceway easily come in contact fatigue wear, and bearing capacity is low, and working life is short.
Because the defect that above-mentioned existing thrust-bearing exists, practical experience and the professional knowledge of the inventor based on being engaged in this type of product specification manufacture and enriching for many years, and the utilization of cooperation scientific principle, actively research and innovation in addition, to founding a kind of inner ring integrated multiple row roller thrust bearing of new structure, can improve general existing thrust-bearing, make it have more practicability.Through constantly research, design, and after repeatedly studying sample and improving, finally create the utility model having practical value.
Summary of the invention
Main purpose of the present utility model is, overcome the defect that existing thrust-bearing exists, a kind of inner ring integrated multiple row roller thrust bearing of new structure is provided, technical problem to be solved is to bear axial load, radial load and tilting moment simultaneously, in the situation that thering is equal axially and radially bearing capacity, can make the radial dimension of bearing greatly dwindle, be widely used in the radially limited occasion of installation dimension.
The purpose of this utility model and solve its technical problem and realize by the following technical solutions.According to a kind of inner ring integrated multiple row roller thrust bearing the utility model proposes, comprise the outer ring 1 of many groups, inner ring 2 and the cylinder rolling element 3 of integrated, outer ring 1 and inner ring 2 arranged radiallys, inner ring 2 external diameter 2.1 places are provided with the V-type mouth of many groups, form V-type groove with outer ring 1 internal diameter 1.1 place's roller surfaces 1.2, cylinder rolling element 3 is in the cross arrangement of V-type groove inner circumference, and the outer ring 1 of many groups, inner ring 2 and the cylinder rolling element 3 of integrated are arranged in order vertically.
The purpose of this utility model and solve its technical problem and also can be applied to the following technical measures to achieve further.
Aforesaid inner ring integrated multiple row roller thrust bearing, this inner ring integrated multiple row roller thrust bearing also comprises rolling elements separator 4, the V-type groove inner circumference cross arrangement that this rolling elements separator 4 forms at outer ring 1 and inner ring 2, and with cylinder rolling element 3 alternately.
The utility model compared with prior art has obvious advantage and beneficial effect.By technique scheme, the utility model at least has following advantages and beneficial effect:
1. outer ring of the present utility model and inner ring arranged radially, make bearing can bear axial load, radial load and tilting moment simultaneously, in the situation that thering is equal axially and radially bearing capacity, can make the radial dimension of bearing reduce, be widely used in the radially limited occasion of installation dimension.
2. rolling element of the present utility model adopts cylindrical roller, and raceway and roller area of contact are large, and contact stress is little, is therefore greatly improved in the bearing capacity of bearing and working life.
3. in the V-shaped groove that the utility model can form at outer ring and inner ring, increase rolling elements separator, with cylinder rolling element alternately, improve limit speed.
4. outer ring of the present utility model quantity is variable, can select according to actual needs the outer ring of many groups to form inner ring integrated multiple row roller thrust bearing.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of specification, and for above and other object of the present utility model, feature and advantage can be become apparent, below especially exemplified by preferred embodiment, and coordinate accompanying drawing, be described in detail as follows.
