Abstract
The utility model relates to the technical field of cylindrical roller bearings, in particular to a double-row reducing cylindrical roller bearing, which comprises outer rings, inner rings, rollers and a retainer. The outer rings, the inner rings and the rollers are in double rows, the rollers are two rows of cylindrical rollers with different inner diameters, inner diameters of the inner rings are different, and the double-row reducing cylindrical roller bearing is used for carrying different loads. Retainer washers are mounted on two sides of the retainer. The double-row reducing cylindrical roller bearing can meet requirements of different loads to rotation speed, and is reasonable in design and long in service life.
Description
Technical field
The utility model relates to the roller bearing technical field, especially a kind of biserial reducing 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, the single-row or Biserial cylindrical roller bearing that the overwhelming majority adopts; Can't tackle the high-revolving requirement of different 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: for solving the deficiency of existing technology, a kind of high-mechanic load is provided, the biserial reducing roller bearing in high working life.
The utility model solves the technological scheme that its technical problem adopted: a kind of biserial reducing roller bearing comprises the outer ring, inner ring; Roller and retainer, outer ring, inner ring; Roller is biserial, and roller is two different line column rollers of internal diameter, and the inner ring internal diameter size is not of uniform size.The row that wherein internal diameter is bigger are in order to bearing main load, and the less row of internal diameter are in order to bearing less important load, thereby the bearing capacity of its load improves a lot, and also be improved its working life.In addition, the retainer both sides all are equipped with retainer packing ring bearing both sides the contact seal circle are housed, interior dress lithium grease, and running temperature is limited to-40 ℃～+ 80 ℃.
The beneficial effect of the utility model is that the biserial reducing roller bearing of the utility model can be tackled different load speed requirements, and is reasonable in design, high life.
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.
Biserial reducing roller bearing as shown in Figure 1 comprises outer ring 1, inner ring 2; Roller 3 and retainer, outer ring 1, inner ring 2, roller 3 are biserial, and roller 3 is two different line column rollers of internal diameter; Inner ring 2 internal diameter sizes are not of uniform size, are used to tackle the different bearer load.The retainer both sides all are equipped with the retainer packing 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 ℃.
With above-mentioned desirable embodiment according to the utility model is enlightenment, and through above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this model utility technological thought.The technical scope of this model utility is not limited to the content on the specification, must confirm its technical scope according to the claim scope.
