Abstract
The utility model relates to a cylindrical roller bearing, in particular to a dual-column full complement cylindrical roller bearing inner ring, which comprises an inner ring body, wherein the outer surface of the inner ring body is provided with two columns of grooves which are used for assembling cylindrical rollers; and an inner triangular groove and an outer triangular groove which are opposite to each other are formed between the two columns of grooves and respectively positioned in the inner surface and the outer surface of the inner ring body. The dual-column full complement cylindrical roller bearing inner ring has the beneficial effects that the triangular grooves are formed in the dual surfaces of the inner ring, so that the bearing inner ring can be recombined into a whole after being fully separated, the working reliability of the bearing is ensured, and the service life is prolonged.
Description
Technical field
The utility model relates to a kind of roller bearing, relates in particular to a kind of double-row full-complement cylinder roller bearing inner ring.
Background technique
General roller bearing is comprised of inner ring, outer ring, retainer and cylindrical roller, and its retainer, cylindrical roller and outer ring or inner ring can become an assembly parts, inner ring or outer ring can with components apart.Utilize just this kind characteristics, mechanically obtain a wide range of applications.
Full-complement cylinder roller bearing designs in order to bear heavy load, and under same width, this bearing is compared with traditional band retainer bearing, has high bearing capacity, and radial cross section and little can be saved the space.The occasion that double-row full-complement cylinder roller bearing is applied in low-speed heave-load is very extensive, not only requirement can be born larger radial load, also requirement can be born certain axial unbalance loading simultaneously, and this structural design for the inner and outer ring of bearing has proposed higher requirement.In addition, because the double-row full-complement cylinder roller bearing inner ring has two raceways, four ribs, this carries out integral body processing or the assembling of disposable finished product of inner sleeve with regard to having determined the bearing that kind of bearings can not be equal to single row roller bearing or other classification.
Domestic general bearing enterprise is processed this series products, often take parts processing grinding bearing inner sleeve, carry out again zoarium during the finished product assembling, but the shortcoming of this type of design is, thereby the dimensional accuracy conformity that not only affects two raceways of bearing inner sleeve and four ribs affects bearing working life, the more important thing is, the inner sleeve after fit can not form an integral body, in use very easily skid, even security incident occurs.
The model utility content
The technical problems to be solved in the utility model is: for the ease of the bearing inner race combination, and the reliability when guaranteeing bearing working, the utility model provides a kind of double-row full-complement cylinder roller bearing inner ring.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of double-row full-complement cylinder roller bearing inner ring, comprise the inner ring body, offer the groove that two row are used for the assembling cylindrical roller on the outer surface of inner ring body, on the internal surface and outer surface of described inner ring body, the centre that is positioned at two row grooves offers respectively relative triangular slot and outer triangular slot.
For the ease of mounting and connection parts, the both sides of described interior triangular slot also offer stepped slot.
In order to gain in strength, the relative and 0.5～1.5mm apart in the groove of described interior triangular slot and outer triangular slot point place.
The beneficial effects of the utility model are, double-row full-complement cylinder roller bearing inner ring of the present utility model, within it the circle two-sided on set up leg-of-mutton groove, can effectively make bearing inner race after separating fully, be reassembled into integral body, reliability when guaranteeing bearing working increases the service life.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the optimum embodiment's of the utility model structural representation.
Among the figure 1, the inner ring body, 2, groove, 3-1, interior triangular slot, 3-2, outer triangular slot, 4, stepped slot.
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.
As shown in Figure 1, the optimum embodiment of the utility model double-row full-complement cylinder roller bearing inner ring, comprise inner ring body 1, offer the groove 2 that two row are used for the assembling cylindrical roller on the outer surface of inner ring body 1, on the internal surface and outer surface of inner ring body 1, the centre that is positioned at two row grooves 2 offers respectively relative triangular slot 3-1 and outer triangular slot 3-2, the both sides of interior triangular slot 3-1 also offer stepped slot 4, the groove of described interior triangular slot 3-1 and outer triangular slot 3-2 point place be groove bottom relatively but do not contact, spacing is 0.5～1.5mm, optimal spacing is 1mm, namely interior triangular slot 3-1 and outer triangular slot 3-2 keep certain middle spacing, can improve the intensity of bearing.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this model utility technological thought, carry out various change and modification fully.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.
