Abstract
The utility model discloses a roller-bearing self-locking light-style integrated body bracket which consists of a plurality of lintels (1), an upper end cover (2) and a lower end cover (3), wherein, the plurality of lintels arranged respectively on the interior sides of both the upper end cover and the lower end cover are an integrated structure. The utility model is characterized in high intensity, high rigidity, compact integrated structure and light weight, etc., completely prevents all kinds of problems caused by the procedure that the bearing is first assembled and then is riveted, thereby effectively improving processing accuracy and productive efficiency, reducing successfully the riveting procedure, decreasing the difficulty to fabricate the integrated bearing, shortening the processing cycle, decreasing the fabrication cost, and prolonging the life span of the bearing. Under the premise that the body bracket is not damaged, the utility model makes the assembly and disassembly of the bearing more convenient. The intensity and the load is much heavier than that of the riveted structure, while the weight is reduced for 40-50 percent or so, therefore, the utility model is very suitable for the bearing with high rotation speed and high precision.
Description
Technical field
The utility model belongs to the retainer technical field, and what relate generally to is a kind of roller bearing self-locking light integral solid cage.
Background technique
Retainer is as one of bearing four big parts, and it mainly acts on is to keep rolling element proper exercise in the bearing, improves the bearing internal load and distributes and greasy property; And under retainer guiding, with guarantee bearing run up and steadily reliable.Therefore, solid cage is highi degree of accuracy, the vital assembly of high-intensity roller bearing.
The solid cage structure of conventional roller bearing adopts a minute body structure more, connect by the closing-up mode, the intensity that it bore can only rely on the riveted intensity of rivet and decide, be Spielpassung between rivet and the retainer rivet hole simultaneously, in bearing operation, certainly will produce the relative displacement phenomenon between the two, thereby make easily between rivet and the nail hole and produce shearing force,, influence the life-span of bearing to such an extent as to cause the rivet root that the tired phenomenon of rupture that produces takes place.Therefore, for high-precision bearing products, the operation that presses again after the bearing trap certainly will influence the overall precision of bearing; And the bearing products behind the riveted is not quick detachable, even its retainer of dismounting back is easy to produce distortion and scrapped, thereby increased bearing manufacture difficulty, prolonged the process-cycle, also increased cost of production simultaneously.
The model utility content
The purpose of this utility model is: propose and design and manufacture a kind of novel roller bearing self-locking light integral solid cage.The weight of this new structure retainer only is the 40-55% of original structure like product, has reduced the manufacture cost of bearing significantly; When having improved retainer intensity, rigidity and geometric accuracy, prolonged the working life of bearing again.This new structure solid cage had both reduced the component parts of former retainer, had reduced the assembly process of bearing again, and easy installation and removal is flexible under the prerequisite of not damaging solid cage.
The utility model realizes that the technological scheme that above-mentioned purpose is taked is: it is made of a plurality of lintels, upper end cap and lower end cap, and described a plurality of lintels distribute and are arranged on the inside circumference of described upper end cap and lower end cap.
The selected material of the utility model still can adopt the selected material of former solid cage, as: materials such as Cuprum alloy, aluminum alloy and steel part, so not only help the processing of product, its groove width can be decided according to the height of rolling element, and pocket hole to the height of basal plane can be decided by the design bearing standard; And the pocket bore portion is evenly distributed on the radially inner side circumference in solid cage pocket hole by bearing roller gyration center line, therefore the distribution number of lintel can be determined according to minimum deck-siding intensity, both can be designed to the retainer in even number pocket hole, also can be designed to the retainer in odd number pocket hole; Because the maximum diameter in the pocket hole that forms between adjacent two lintels is slightly less than selected rolling element diameter dimension, thereby making rolling element and pocket hole is the interference assembly relation, realize auto-lock function, and can guarantee that rolling element only is subjected to the retainer pocket hole of can freely coming in and going out under the situation of certain external force.
The utlity model has high strength, high rigidity and compact overall structure, characteristics such as slim and graceful, the variety of issue that operation produced such as avoided fully pressing again after the bearing trap, machining accuracy and manufacturing efficiency have been improved effectively, and successfully reduced the closing-up operation, reduced solid bearing manufacture difficulty, shortened the process-cycle, reduce cost of production, prolonged the working life of bearing.Under the prerequisite of not damaging solid cage, make the installation trap of bearing and tear cover open freely convenient.Because it be the integrated type retainer, big a lot of of its intensity and the duty ratio riveted type structure of being born, the common retainer of weight ratio has alleviated about 40%～50%, is highly suitable for high rotating speed, the use of high-precision bearing.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is Figure 1A-A sectional view.
Fig. 3 is the partial enlarged drawing of Fig. 1.
Among the figure: 1, lintel, 2, the upper end portion, 3, the underpart, 4, rolling element, 5, the inner arc pocket, 6, the lock point.
Embodiment
In conjunction with the accompanying drawings, it is as follows to provide embodiment of the present utility model:
As Fig. 1 in conjunction with shown in Figure 2: the utility model embodiment is made of upper end portion 2, underpart 3 and a plurality of lintel 1, and described a plurality of lintels 1 distribute and are arranged on the inboard of upper end portion 2 and underpart 3, and it is an overall structure.The upper-end surface of lintel 1 is parallel with the upper-end surface of upper end portion 2, and its lower end surface is parallel with 3 lower end surfaces, underpart.Lintel 1 both can be and had been designed to even number, also can be designed to the odd number hole; And the maximum diameter in the pocket hole that forms between adjacent two lintels 1 is slightly less than selected rolling element diameter dimension, thereby makes rolling element 4 and pocket hole 5 be the interference assembly relation.Make rolling element in this retainer pocket hole, carry out the work running, guarantee rolling element smooth operation in retainer pocket hole.Inner arc pocket 5 parts (as shown in Figure 3) in the pocket hole, diameter is more bigger than rolling element, is the working surface of rolling element guiding retainer, keeps the rolling element proper exercise, and can improve the bearing internal load and distribute and greasy property.Effect of its lock point 6 is after rolling element is installed trap, under the effect of not forced external force, makes rolling element keep proper exercise in the pocket hole and can not drop out.
