Abstract
The utility model belongs to technical field of rolling bearings, specifically a kind of dedicated outer guidance Biserial cylindrical roller bearing of Vertical Mill.The bearing includes outer ring, inner ring, rolling element, retainer, the retainer are revealed all the details on external diameter surface circumferencial direction with boss, the boss outer diameter Machining Arc groove, retainer rib end face processes 17 ' angles, and there are guide clearances for internal diameter and retainer outer radial position outside outer ring.The utility model bearing drives retainer rotation after guaranteeing outer ring rotation, and retainer pushes rolling element rotation, and flexibility of revolution is good；Lubrication can be increased in boss outer diameter Machining Arc groove；In rib end face, 17 ' angles of processing can guarantee the lubrication of rib and rolling body end surface, oil circuit it is unimpeded.
Description
Technical field
The utility model belongs to technical field of rolling bearings, specifically a kind of dedicated outer guidance double-row cylindrical roller axis of Vertical Mill
It holds.
Background technique
With being substantially improved for the mechanical research and development technology that is milled, the Vertical Mill technology of external flour mill manufacturing enterprise is day by day
The product technology advantage of maturation, Vertical Mill is also increasingly prominent.Under these circumstances, domestic flour mill manufacturing enterprise draws successful foreign
Experience has carried out important technical reform, and the principle of actual Vertical Mill is that motor band movable grinding disc rotates, and material is fallen from feed opening
Mobile to mill edge under the influence of centrifugal force and rolled by grinding roller to mill center, grinding roller is under the action of grinding pressure
Start to rotate, bearing is the critical component of grinding roller of vertical mill, and roll surface and bearing outer ring cooperate, therefore grinding roller bearing is actually outer
Circle rotation, traditional grinding roller of vertical mill bearing are guided using rolling element, while the retainer weight of general Vertical Mill is all bigger, rolls
Body pushes retainer rotation, and flexibility of revolution is poor, it is therefore desirable to improve to existing bearing arrangement.
Summary of the invention
In order to solve the above technical problems, the utility model provides a kind of dedicated outer guidance Biserial cylindrical roller bearing of Vertical Mill.
For achieving the above object, the utility model uses following technical scheme:
A kind of dedicated outer guidance Biserial cylindrical roller bearing of Vertical Mill, including outer ring, inner ring, rolling element, retainer, the guarantor
It holds frame to reveal all the details with boss on external diameter surface circumferencial direction, the boss outer diameter Machining Arc groove, retainer rib end face adds
17 ' angle of work, there are guide clearances for internal diameter and retainer outer radial position outside outer ring.
Compared with prior art, the invention has the benefit that bearing of the present invention drives holding after guaranteeing outer ring rotation
Frame rotation, retainer push rolling element rotation, and flexibility of revolution is good；Lubrication can be increased in boss outer diameter Machining Arc groove；
In rib end face, 17 ' angles of processing can guarantee the lubrication of rib and rolling body end surface, oil circuit it is unimpeded.
Detailed description of the invention
Fig. 1 the utility model structure diagram；
Fig. 2 the utility model retainer left view；
Fig. 3 the utility model retainer main view.
Specific embodiment
The utility model is further described below in conjunction with attached drawing.
A kind of dedicated outer guidance Biserial cylindrical roller bearing of Vertical Mill, including outer ring 01, inner ring 02, rolling element 04, retainer
56, the retainer 56 is revealed all the details with boss 07 on external diameter surface circumferencial direction, in 56 outer diameter of the outer internal diameter in outer ring 01 and retainer
Position guarantees to drive retainer rotation after outer ring rotates, retainer pushes rolling element rotation, rotation spirit there are guide clearance 06
Activity is good；In the boss outer diameter Machining Arc groove 08, can prevent because retainer guide due to existing for contact area it is excessive fall
The phenomenon that copper scale, while playing the role of increasing lubrication；Retainer rib end face processes 17 ' angles 05, can control and rolls body end
Face and rib contact position, while also can guarantee the lubrication of rib and rolling body end surface, oil circuit it is unimpeded.
Bearing arrangement of the present invention is bearing outer ring rotation, and inner ring is fixed, and outer ring drives retainer rotation, and retainer drives rolling
Kinetoplast rotation drove retainer rotation by rolling element in the past to change, and improved flexibility of revolution.
