Abstract
The utility model relates to the technical field of a cylindrical roller bearing, in particular to a double-row cylindrical roller bearing. The double-row cylindrical roller bearing comprises an outer ring, two inner rings, rollers and a retainer, wherein the two inner rings are connected together through a clamping ring, the outer ring is provided with a middle flange, and the surface of the outer ring is provided with two snap grooves. Two sides of the bearing are provided with contact type sealing rings which are filled with lithium-based greases, and the operating temperature is limited between 40 DEG C below zero and 80 DEG C above zero. The double-row cylindrical roller bearing has compact structure, convenience for installing, flexible operation, strong rigidity, large bearing capacity and small deformation after being loaded and is mostly used for bearing machine tool spindles.
Description
Technical field
The utility model relates to the roller bearing technical field, especially a kind of Biserial cylindrical roller bearing.
Background technique
In industries such as automobile, milling train, mine, metallurgy, plastics machineries; Can require has supporting design bearing, often can use roller bearing, and the overwhelming majority adopts single row roller bearing; Can't tackle the high-revolving requirement of high load; Because bearing capacity is lower, the rotation underaction has certain influence in usability with on working life.
The model utility content
The technical problem that the utility model will solve is: solve the deficiency of existing technology, a kind of Biserial cylindrical roller bearing is provided.
The utility model solves the technological scheme that its technical problem adopted: a kind of Biserial cylindrical roller bearing is characterized in that: comprise the outer ring, two inner rings; Roller and retainer; Two inner rings by wheel flange be linked together, inseparable, there is a centre rib outer ring; Can bear two-way axial load, as positioning bearing.Because the distance between the two row rollers is bigger, also can bear tilting moment.There are two locking grooves on the surface, outer ring, can axially locating.This profile shaft holds both sides the contact seal circle is housed, interior dress lithium grease, and running temperature is limited to-40 ℃～+ 80 ℃.Under certain conditions, this profile shaft holds service free, but when operation, steam or pollution is arranged, and often is middling speed or high speed operation, then must supplemental lubrication.In the occasion that adopts oil lubricating, need to remove seal ring, and the lubricating grease in the bearing cleaning, improve 30% in changeing when adopting oil lubricating.
There are two locking grooves on the surface, outer ring.The contact seal circle is equipped with in the bearing both sides, interior dress lithium grease, and running temperature is limited to-40 ℃～+ 80 ℃.
The beneficial effect of the utility model is, the biserial cylindrical roller bearing structure of the utility model is compact, and is easy for installation, flexible operation, rigidity is strong, bearing capacity is big, receive load after distortion little, be used for the supporting of machine tool chief axis mostly.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model.
1. outer rings among the figure, 2. inner ring, 3. roller.
Embodiment
Combine accompanying drawing that the utility model is done further detailed explanation now.These accompanying drawings are the schematic representation of simplification, the basic structure of the utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
A kind of Biserial cylindrical roller bearing as shown in Figure 1 comprises 1, two inner ring 2 in outer ring, roller 3 and retainer, two inner rings 2 by wheel flange be linked together, there is a centre rib outer ring 1, can bear two-way axial load, as positioning bearing.Because the distance between the two row rollers 3 is bigger, also can bear tilting moment.There are two locking grooves on 1 surface, outer ring.The contact seal circle is equipped with in the bearing both sides, interior dress lithium grease, and running temperature is limited to-40 ℃～+ 80 ℃.
Under certain conditions, this profile shaft holds service free, but when operation, steam or pollution is arranged, and often is middling speed or high speed operation, then must supplemental lubrication.In the occasion that adopts oil lubricating, need to remove seal ring, and the lubricating grease in the bearing cleaning, improve 30% in changeing when adopting oil lubricating.
