Abstract
The utility model relates to a double-line cylindrical roller bearing, comprising a bearing outer ring, a bearing inner ring and cylindrical rollers, wherein two rolling chambers matched with the cylindrical rollers in shape are arranged between the bearing outer ring and the bearing inner ring along the axial direction; a plurality of cylindrical rollers sequentially cling to the inside of the rolling chambers; the rolling chambers are located between the bearing outer ring and the bearing inner ring; the two rolling chambers are respectively provided with a sealed channel communicated with the outside, and the sealed channels face the bearing outer ring; and the sealed channels are internally provided with sealing rings in a clamping way. By adopting the scheme, the utility model provides the double-line cylindrical roller bearing with a good sealing effect.
Description
Technical field
The utility model relates to a kind of roller bearing, is specifically related to a kind of Biserial cylindrical roller bearing.
Background technique
Roller bearing is that rolling element is the rolling bearing of cylindrical roller, while being particularly applied to stone machining equipment roller because needs load is larger, two roller bearings arranged side by side of general employing guarantee bearing capacity, this common roller bearing comprises bearing outer ring, bearing inner race, cylindrical roller and retainer, but again because the working environment of stone machining equipment roller is poor, often there is the mixture of stone flour bits or water and stone flour bits to enter cylindrical roller from the space between bearing outer ring, bearing inner race, had a greatly reduced quality the working life of roller bearing.
Common roller bearing is owing to being provided with retainer, being difficult to increases seal ring in the space between bearing outer ring and bearing inner race again, for addressing the above problem, can only be at outside other sealing means that adopt of bearing, but because of machining accuracy, the reasons such as sealing means, cause sealing effect still not good, stone machining equipment roller water and stone flour bits around still can enter bearing inside, thereby cause the inefficacy of bearing.
Summary of the invention
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of Biserial cylindrical roller bearing of good sealing effect.
For achieving the above object, the utility model provides following technological scheme: comprise bearing outer ring, bearing inner race and cylindrical roller, it is characterized in that: between described bearing outer ring and bearing inner race, be provided with vertically the suitable rolling chamber of two shapes and cylindrical roller, in described rolling chamber, laminating is provided with several cylindrical rollers successively, there is towards bearing outer ring arranged outside the sealing channel being connected with the external world in two described rolling chambeies respectively, in described sealing channel, are arranged with seal ring.
By adopting technique scheme, adopt the not full roller designs with retainer, give between bearing outer ring and bearing inner race and reserve sufficient space for seal ring is installed, guarantee its sealability, secondly, the design of full roller has also increased the load capacity of bearing, is well suited for the working condition of this low speed high loading of stone machining equipment roller.
The utility model is further set to: between two described rolling chambeies, be provided with communication passage, on described bearing outer ring, be provided with by communication passage and extraneous UNICOM for injecting the greasing hole of lubricating grease.
By adopting technique scheme, lubricating grease is entered rolling chamber cylindrical roller is lubricated by the greasing hole communication passage of flowing through again, reduces the friction between itself and rolling chamber, increases the service life.
The utility model is further set to: described seal ring comprises the base portion fitting with bearing outer ring and the spring section fitting with bearing inner race, described spring section is that cross section is leg-of-mutton annular construction member, described triangle is the fixed edge fixing with base portion on one side, the end points that described fixed edge is relative tilts to bearing outer ring outside, the limit of described fixed edge one side outside bearing outer ring is as the limit that stops of block water and stone flour bits, and the limit of opposite side inside bearing outer ring be the leading edge to outside as guiding lubricating grease.
By adopting technique scheme, base portion guarantees seal ring stability, conventionally the member that cross section is rectangle, spring section both can be for having stopped block water and stone flour bits, can also be when the supplemental lubrication fat of greasing hole, the lubricating grease that is mixing stone flour bits being squeezed is guided out to rolling chamber, further improves the practicability of whole bearing.
The utility model is further set to: between described base portion and spring section, be provided with the joint that cross section is strip.
By adopting technique scheme, joint is set position and the angle of being convenient to adjustable elastic portion, make its Applicable scope wider.
The utility model is further set to: the described corresponding rolling of bearing inner race chamber is divided into the inner ring left part and the inner ring right part that fit, between described inner ring left part and the inner ring right part inner peripheral surface near laminating end, be arranged with the spring that cross section is U-shaped, described inner ring left part and inner ring right part are respectively arranged with the draw-in groove suitable with the bending shape of spring U-shaped both sides.
By adopting technique scheme, bearing inner race is divided into inner ring left part and inner ring right part and is convenient to the installation of cylindrical roller, secondly by U-shaped spring, both are fixed, convenient fixing, takes up room little.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
