Description
[technical field]
This utility model relates to a kind of bearing, especially relates to a kind of Biserial cylindrical roller bearing.
[background technology]
Known, the Biserial cylindrical roller bearing of current conventional structure, it is applicable to the operating mode that varions type load is little, and
For some occasions exigent to bearing load carrying capacity, such as the bearing used on disintegrating machine, the biggest owing to carry
Bearing capacity, the most just requires that bearing also can not reduce service life in the case of bearing the biggest load, the most also requires axle
Hold locus constant in the case of, improve load holding capacity, say, that the intensity of retainer to be ensured, and rolling
Kinetoplast quantity can not be too many, but, current Biserial cylindrical roller bearing does not possess such function, thus causes bearing specified
Dynamic loading is difficult to improve.
[utility model content]
In order to overcome the deficiency in background technology, the utility model discloses a kind of Biserial cylindrical roller bearing, this practicality
Novel by arranging biserial rolling element and back-up ring on the retainer of inner ring and outer ring, and biserial rolling element is set side by side
Put, while reaching to improve specified dynamic load load with this, do not change the purpose of bearing space position.
In order to realize described utility model purpose, this utility model adopts the following technical scheme that
A kind of Biserial cylindrical roller bearing, including inner ring, outer ring, rolling element, retainer, back-up ring and fixed block, inner ring and
Being provided with retainer between outer ring, retainer is provided with two row rolling elements, and rolling element is cylindrical structure, is provided with gear on retainer
Circle, back-up ring is provided with fixed block, and two row rolling elements on retainer are disposed in parallel on retainer.
Described shield ring sleeve, on retainer, is provided with fixed block on the lateral surface of back-up ring.
Described fixed block is column type or prismatic structure, and fixed block is connected with back-up ring by riveting, and fixed block is right
Structure is claimed to be arranged on the two sides of back-up ring.
Two row rolling elements on described retainer are arranged on retainer by back-up ring, and two row rolling elements are one_to_one corresponding knot
Structure, the structure often arranging rolling element is that size arranges, and the size of each column rolling element alternately arranges.
Owing to have employed technique scheme, this utility model has the advantages that
A kind of Biserial cylindrical roller bearing described in the utility model, including inner ring, outer ring, rolling element, retainer, back-up ring
And fixed block, by arranging biserial rolling element and back-up ring on the retainer of inner ring and outer ring, and by biserial rolling element and discharge into
Row is arranged, and does not change the purpose of bearing space position with this while reaching to improve specified dynamic load load；This utility model is real
Strong by property, process and assemble up the most fairly simple, be not only able to effectively improve specified dynamic load load, and make bearing empty
Between invariant position, meet the needs of routine work greatly.
[accompanying drawing explanation]
Fig. 1 is structural representation of the present utility model；
In figure: 1, outer ring；2, fixed block；3, inner ring；4, retainer；5, back-up ring；6, rolling element.
[detailed description of the invention]
Explanation this utility model that can be detailed by the following examples, open the purpose of this utility model is intended to protection
All technological improvements in the range of this utility model.
In conjunction with a kind of Biserial cylindrical roller bearing described in accompanying drawing 1, including inner ring 3, outer ring 1, rolling element 6, retainer 4,
Back-up ring 5 and fixed block 2, be provided with retainer 4 between inner ring 3 and outer ring 1, retainer 4 is provided with two row rolling elements 6, and rolling element 6 is
Cylindrical structure, is provided with back-up ring 5 on retainer 4, and back-up ring 5 is provided with fixed block 2, and two row rolling elements 6 on retainer 4 are arranged side by side
It is arranged on retainer 4；Described back-up ring 5 is enclosed within retainer 4, is provided with fixed block 2 on the lateral surface of back-up ring 5；Described fixing
Block 2 is column type or prismatic structure, and fixed block 2 is connected with back-up ring 5 by riveting, and fixed block 2 symmetrically structure is arranged on
On the two sides of back-up ring 5；Two row rolling elements 6 on described retainer 4 are arranged on retainer 4 by back-up ring 5, two row rolling elements
6 in one_to_one corresponding structure, and often the structure of row's rolling element 6 is that size arranges, and the size of each column rolling element 6 is alternately arranged
Row.
Implement a kind of Biserial cylindrical roller bearing described in the utility model, when in use, owing to rolling element 6 is being protected
Holding and be arranged side by side on frame 4, and two row rolling elements 6 are in one_to_one corresponding structure, often the structure of row's rolling element 6 is that size is carried out
Arrangement, the size of each column rolling element 6 alternately arranges, so it is to say, be by two greatly in each hole on retainer 4
Little different rolling element 6 is combined into a big roller, and the size of two row rolling elements 4 is that intersection arranges, and is so
The quantity of rolling element is not the most increased, say, that not only can carry bigger while can meeting bigger bearing load
Load, and the position of bearing space keeps constant, thus meet the requirement of actual production greatly.
Although specifically showing in conjunction with preferred embodiment and describing this utility model, implement this technical scheme method
A lot of with approach, the above is only preferred implementation of the present utility model, but those skilled in the art should be understood that
In the spirit and scope of the present utility model limited without departing from appended claims, in the form and details can be right
This utility model makes a variety of changes, and is protection domain of the present utility model.
