This roller bearing to supplementary rolling element replaces the holder structure, becomes rolling friction with sliding friction, reduces the energy consumption, improve equipment performance.

Description

Roller bearing

Technical field

The utility model relates to a kind of bearing, particularly relates to a kind of roller bearing.

Background technology

Existing bearing is mainly retainer structure, forms framework knot with certain material as steel, copper, polyurethaneStructure, frame is lived rolling element, as the interval of rolling element. Between retainer and rolling element, be sliding friction, frictionCan reduce the rotating speed of roller, friction can make roller and retainer produce damage and produce heat simultaneously. Load, simultaneouslyRotating speed, vibrational loading, impact load, rotary centrifugal force all can aggravate the friction between retainer and roller.Existing cylinder roller bearing is widely used, and is divided into single-row roller, biserial roller, three row rollers, four row rollersAnd six row roller etc.; Each row roller all along be circumferentially evenly inlaid on fixed mount and with outside cylindrical shell phaseCut. When bearing bears load when larger, as milling train, coal pulverizer, bearing need to increase roller columns and bearLarger load. After but columns increases and roller quantity increases, the frictional resistance producing between itself and fixed mountIncrease, become very important, affect serviceability.

Summary of the invention

In order to solve the problems of the technologies described above, the utility model provides a kind of roller bearing, does not need fixed mount to fixRoller, becomes rolling friction by sliding friction, reduces energy consumption, improves equipment serviceability.

For this reason, the technical solution of the utility model is as follows:

A kind of roller bearing, comprises the enclosed cavity that can take apart and is arranged at the master in the described enclosed cavity that can take apartRolling element and auxiliary rolling element, described main rolling element has multiple, along being circumferentially set in parallel in described can taking apartIn enclosed cavity, described main rolling element is tangent is between any two provided with auxiliary rolling element; Described auxiliary rolling element is flatRow is provided with two rows, is distributed in respectively described main rolling element both sides.

Further, described main rolling element, auxiliary rolling element be spherical simultaneously or be cylindric simultaneously, orBe round table-like simultaneously.

Preferably, when described main rolling element, auxiliary rolling element are while being cylindric or round table-like simultaneously, described master rollsThe two ends of kinetoplast are formed with the boss for blocking described auxiliary rolling element.

Further, when described main rolling element, auxiliary rolling element are while being cylindric, round table-like simultaneously, described energyThe enclosed cavity of taking apart is that outer ring, inner ring form after annular end cap is installed at two ends.

Further, when described main rolling element, auxiliary rolling element are while being spherical simultaneously, the described sealing that can take apartChamber is to form after upper cover, lower cover are installed as one.

The design principle of the roller bearing that the utility model provides is: as shown in Figure 1, and when two circles are tangential onBetween two parallel planes time, when a circle rotation is advanced, another circle rotation in the other direction rotation is advanced; No matter twoWhether circular diameter size is identical, and its angular speed equates. Disclosed the rolling of the utility model of utilizing this principle to obtainSub-bearing, it,, to assist roller to replace retainer structure, can reduce friction, increases load, limit speed.This design is applicable to long cylindrical roller bearing, taper roll bearing and plain thrust bearing.

Detailed description of the invention

Below in conjunction with drawings and Examples, structure of the present utility model is described in detail.

Embodiment 1

A kind of long cylindrical roller bearing, comprises outer ring 1, inner ring 2, annular end cap 5, main rolling element 3 and auxiliaryHelp rolling element 4; Outer ring 1, inner ring 2 are cylindric, and the rear formation sealing of annular end cap 5 is installed at its two endsChamber; The outer surface of the inner surface of outer ring 1 and inner ring 2 parallels; Main rolling element 3 is for long in the present embodimentCylindrical roller; Outer ring 1, inner ring 2 are circumferentially arranged with in parallel multiple with the interior edge of enclosed cavity that annular end cap 5 formsLong cylinder roller 3; Long cylinder roller 3 is provided with auxiliary rolling element 4 between any two; It is auxiliary that rolling element 4 is parallel establishesBe equipped with two rows, be distributed in respectively the two ends of long cylinder roller 3; The two ends of long cylinder roller 3 be formed with forBlock the boss of auxiliary rolling element 4.

When work, in the time that long cylinder roller 3 moves, the auxiliary rolling element 4 of its both sides is with identical angular speedRotate round about; Be that main and auxiliary rolling element advances at upper and lower two parallel orbital plane synchronous rotaries. ShouldLong cylindrical roller bearing, to assist rolling element to replace retainer structure, can reduce friction, increases load, the utmost pointLimit rotating speed.

Embodiment 2

A kind of taper roll bearing, comprises outer ring, inner ring, annular end cap, main rolling element and auxiliary rolling element;The main and auxiliary rolling element that helps is all round table-like; After outer ring, inner ring and annular end cap assembling, form enclosed cavity; This envelopeClose edge in chamber and be circumferentially arranged with multiple main rolling elements in parallel, the axis of each main rolling element converges at a bit; MainRolling element is provided with auxiliary rolling element between any two; Auxiliary rolling element is arranged with two rows in parallel, is distributed in respectively masterThe two ends of rolling element; The two ends of main rolling element are formed with the boss for blocking auxiliary rolling element.

This taper roll bearing, to assist rolling element to replace retainer structure, can reduce friction, increase load,Limit speed.
