Description
Technical field
The invention belongs to technical field of bearings is and in particular to a kind of Biserial cylindrical roller bearing.
Background technology
Bearing is a kind of important spare part in contemporary plant equipment.During bearing uses, for reducing its motor process
In coefficient of friction, and ensure its rotating accuracy, improve bearing service life, must must add between the outer ring of bearing and inner ring
Plus lubricant, for biserial or many line column roller bearings, with the lengthening of bearing use time, lubricant can be gradually
Constantly pile up to roller both sides, for being, especially for roller, the multiple row roller bearing that inclination is laid, its lubricant can be constantly
Ground is piled up so that lubricant is not fully utilized to the position between adjacent two row rollers, causes other positions weary lubrication, just
Lubricant must be mended, shorten the cycle mending lubricant, increase the number of times mending lubricant, cause the waste of lubricant, increase equipment dimension
Shield cost.
Content of the invention
For the problems referred to above, the problem to be solved in the present invention is to provide one kind effectively to prevent lubricant heap between two row rollers
Long-pending, so that lubricant is fully utilized, allow other positions of roller obtain sufficient lubrication, extend the cycle mending lubricant, reduce and mend
The number of times of lubricant, saves lubricant, the Biserial cylindrical roller bearing of reduces cost.
A kind of Biserial cylindrical roller bearing, including outer ring, inner ring, retainer, sealing ring；The inner surface of described outer ring with interior
The outer surface edge of circle is designed with rib；Described retainer is arranged between outer ring and inner ring, and retainer is provided with two row rectangles
Through hole, the number of each column through hole is all identical with size；It is provided with a cylindrical roller, described sealing ring is located at outer in each through hole
On edge between circle and inner ring；It is recessed that the inner surface central authorities of described outer ring and the outer surface central authorities of inner ring are respectively provided with an annular
Groove, groove one and groove four；It is respectively provided with the two row rectangles being located at retainer on the outer surface of described retainer and inner surface
Annular groove between through hole, groove two and groove three；Described groove two is corresponding with groove one position, groove two and groove one it
Between be filled with many balls one, described groove three is corresponding with groove four position, is filled with many between groove three and groove four
Ball two.
Further, ball one is identical with ball two shape size.
Further, described sealing ring is abrasive rubber circle.
The present invention is by by way of installing ball additional between two row rollers, effectively preventing lubricant heap between two row rollers
Long-pending, so that lubricant is fully utilized, allow other positions of roller obtain sufficient lubrication, extend the cycle mending lubricant, reduce and mend
The number of times of lubricant, saves lubricant, reduces the maintenance cost of equipment.

Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.
A kind of Biserial cylindrical roller bearing as shown in Figures 1 to 4, including outer ring 1, inner ring 4, retainer 2, sealing ring 3；
The inner surface of described outer ring 1 and the outer surface edge of inner ring 4 are designed with rib；Described retainer 2 is arranged on outer ring 1 and inner ring 4
Between, retainer 2 is provided with two row rectangular through-hole 12, and the number of each column through hole 12 is all identical with size；Set in each through hole 12
There is a cylindrical roller 5, described sealing ring 3 is located on the edge between outer ring 1 and inner ring 4；In the inner surface of described outer ring 1
Centre is respectively provided with an annular groove, groove 1 and groove 46 with the outer surface central authorities of inner ring 4；The outer surface of described retainer 2
And annular groove between the two row rectangular through-hole 12 being located at retainer 2, groove 29 and groove 38 are respectively provided with inner surface；
Described groove 29 is corresponding with groove 1 position, is filled with many balls 1 between groove 29 and groove 1, described
Groove 38 is corresponding with groove 46 position, is filled with many balls 27 between groove 38 and groove 46.
Further, ball one（10）With ball two（7）Shape size is identical.
Further, described sealing ring 3 is abrasive rubber circle.
The present invention is by by way of installing ball additional between two row rollers, effectively preventing lubricant heap between two row rollers
Long-pending, so that lubricant is fully utilized, allow other positions of roller obtain sufficient lubrication, extend the cycle mending lubricant, reduce and mend
The number of times of lubricant, saves lubricant, reduces the maintenance cost of equipment.
