Abstract
The utility model relates to the technical field of bearings and particularly relates to a lubrication type combined thrust bearing comprising a first raceway ring and a second raceway ring, wherein a column of spherical balls are arranged between the first raceway ring and the second raceway ring; the lower surface of the second raceway ring is provided with a column of roller pins through a retainer; the outer ring of the second raceway ring is provided with an oil injection hole. The lubrication type combined thrust bearing provided by the utility model is reasonable in design, high in rigidity, high in bearing capacity, good in lubricating effect, small in friction, suitable for rotating at high speed and capable of being matched with an assembling shell to realize the precise and axial location of the bearing and ensure that the assembled bearing is favorable in use performance and long in service life.
Description
Technical field
The utility model relates to technical field of bearings, especially a kind of lubricating type combined type thrust-bearing.
Background technique
Bearing is all used on some equipment of all trades and professions and utensil widely, and at practical situations such as the structural feature of equipment, load that bearing is estimated carrying and Environmental Conditions, it is varied that the kind model of bearing also presents, complete.Common bearing is being used for all kinds of load-carrying vehicles and at a high speed, and during high load-carrying running, it is bigger wear and tear, not shock-resistant, is not suitable for bearing heavy load, and because lubrication effect is poor, long-term rotation at a high speed causes bearing breaking easily, working life weak point.
The model utility content
The technical problems to be solved in the utility model is: for overcoming the problem of above-mentioned existence, provide a kind of load-carrying vehicle and machinery of being applicable to, high load-carrying, the lubricating type combined type thrust-bearing of long-life.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of lubricating type combined type thrust-bearing, comprise the first raceway circle and the second raceway circle, be provided with a row spherical ball between the described first raceway circle and the second raceway circle, set up a row needle roller by retainer on the described second raceway circle lower surface, the described second raceway circle outer ring offers oil hole.
Further, described spherical ball is outside equipped with back-up ring.
Further, described lubricating type combined type thrust-bearing is the divergence type bearing.
The beneficial effects of the utility model are, lubricating type combined type thrust-bearing of the present utility model is reasonable in design, and it is little to take up room, be conducive to the compact design of machinery, easy for installation, flexible operation, rigidity is strong, and bearing capacity is bigger, high lubricating effect, it is little to rub, be suitable for rotation at a high speed, can cooperate with assembling shell, realize bearing is carried out accurate axially locating, make bearing assembling back usability good, high life.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
1. first raceway circles among the figure, the 2. second raceway circle, 3. spherical ball, 4. needle roller, 5. back-up ring, 6. oil hole.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Lubricating type combined type thrust-bearing as shown in Figure 1, comprise the first raceway circle 1 and the second raceway circle 2, be provided with a row spherical ball 3 between the first raceway circle 1 and the second raceway circle 2, set up a row needle roller 4, the second raceway circles 2 outer rings by retainer on the second raceway circle, 2 lower surfaces and offered oil hole 6.Spherical ball 3 is outside equipped with back-up ring 5.Wherein, lubricating type combined type thrust-bearing is the divergence type bearing.
Be enlightenment with above-mentioned foundation desirable embodiment of the present utility model, by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
