Abstract

The invention discloses a double-row tapered roller alignment heavy load sliding bearing and provides a sliding bearing which is used for combining a knuckle bearing and a roller bearing together. The sliding bearing comprises an outer ring and a first inner ring, and the outer ring and the first inner ring constitute the knuckle bearing. The sliding bearing is characterized in that a second inner ring is arranged in the inner cavity of the first inner ring, a holder is arranged between the second inner ring and the first inner ring, and the holder is provided with rollers, and the first inner ring, the second inner ring, the rollers and the holder constitute the roller bearing. The first inner ring is taken as the inner ring of the knuckle bearing and the outer ring of the roller bearing at the same time, and the first inner ring is shared by the knuckle bearing and the roller bearing. Two groups of rollers are arranged on the roller bearing, the axes of the two groups of rollers respectively form acute angles with the axis of the second inner ring, and the two groups of rollers are symmetrically arranged, so that on the one hand, the good mobility between the first inner ring and the second inner ring is ensured, on the other hand, the sliding bearing has an automatic alignment function, high in load capacity and good in stability.

Description

Double-row conical aligning heavy load sliding bearing
Technical field
The present invention relates to joint shaft bearing technical field, specifically the assemblying body of a kind of joint shaft bearing and roller bearing.
Background technique
Joint shaft bearing mainly has the sliding bearing of the inner ring of outer spherical surface and a special construction having the outer ring of inner ball surface to form by one, can bear larger load.The structural rate rolling bearing of joint shaft bearing is simple, and it is mainly made up of the outer ring of inner ball surface the inner ring of outer spherical surface and one by one.Joint shaft bearing is generally used for the lower oscillating motion of speed (i.e. angular motion), because slidingsurface is spheric, also can make banking motion (i.e. aligning motion) within the scope of several angle, supporting axle and axle housing hole nonconcentricity larger time, still can normally work.Roller bearing is the roller bearing of band cylindrical roller, its diameter relatively, and roller is thin but also length not only.Mixing plant for building using more is roller bearing, can not carry out Self-aligning, and be not easy to install, load capacity is little.In addition, roller bearing is directly installed on equipment, if the bearing support position wearing and tearing of equipment or damage, will directly affect the use of equipment.
Summary of the invention
The object of the present invention is to provide a kind of double-row conical aligning heavy load sliding bearing joint shaft bearing and roller bearing combined.
The present invention solves the technological scheme that its technical problem takes: double-row conical aligning heavy load sliding bearing, comprise outer ring and the first inner ring, described outer ring and the first inner ring form a joint shaft bearing, it is characterized in that, the second inner ring is provided with in the inner chamber of described first inner ring, between described second inner ring and the first inner ring, be provided with retainer, described retainer is provided with roller, described first inner ring, the second inner ring, roller and retainer constitute roller bearing.
Further, described outer ring is two slotting structures.
Further, described outer ring inner ball surface is provided with self-lubricating composite PTFE.
Further, described first inner ring outer spherical surface carries out the process of plating Lip river or phosphorating treatment.
Further, described retainer is two, and two retainers are symmetrical arranged about the symmetry plane of the second inner ring, and some rollers are separately positioned on two retainers.
Further, described roller comprises the first roller and the second roller, described first roller is identical with the structure shape of the second roller, described first roller is arranged on one of them retainer, described second roller is arranged on another retainer, the axis of described first roller and the axis of the second inner ring acutangulate angle, and the axis of described second roller and the axis of the second inner ring acutangulate angle, and some described first rollers and some second rollers are symmetrical arranged.
The invention has the beneficial effects as follows: double-row conical aligning heavy load sliding bearing provided by the invention, comprise joint shaft bearing and the roller bearing being positioned at joint shaft bearing inside, first inner ring is as the inner ring of joint shaft bearing, simultaneously as the outer ring of roller bearing, namely joint shaft bearing and roller bearing share the first inner ring.Roller bearing arranges two groups of rollers, i.e. the first roller and the second roller, the axis of two groups of rollers acutangulates angle with the second inner ring axis respectively and arranges, and two groups of rollers are symmetrical arranged, ensure that mobility good between the first inner ring and the second inner ring on the one hand, on the other hand, symmetrically arranged roller avoids the axial displacement between the second inner ring and the first inner ring, have Self-aligning function, easy to use, stability is better.

Embodiment
As shown in Figures 1 to 7, the present invention includes outer ring 1, first inner ring 2, second inner ring 3, first roller 4 and the second roller 5, below in conjunction with accompanying drawing, present invention is described.
As shown in Figure 1, double-row conical aligning heavy load sliding bearing of the present invention comprises a joint shaft bearing and a roller bearing, and roller bearing is embedded in the inside of joint shaft bearing.As shown in Figures 2 to 4, joint shaft bearing comprises the inside that outer ring 1 and the first inner ring 2, first inner ring are embedded in outer ring, both relative slidings.The joint shaft bearing be made up of outer ring 1 and the first inner ring 2 is prior art, commercially available.Outer ring is two slotting structures or single slotting structure, and the inner ball surface of outer ring is provided with self-lubricating composite PTFE.The outer spherical surface of the first inner ring carries out chromium plating process or phosphorating treatment, and object improves wear resistance, prevents surface peeling, play antistatic or anticorrosion ability.Be provided with the second inner ring 3, first roller 4 and the second roller 5 in the inside of the first inner ring, as shown in Figure 5, the first inner ring 2, second inner ring 3, first roller 4 and the second roller 5 constitute roller bearing.First inner ring is equivalent to the outer ring of this roller bearing, the second inner ring 3 is provided with in the inside of the first inner ring, this the second inner ring is equivalent to the inner ring of roller bearing, some two groups of rollers are provided with between the first inner ring and the second inner ring, be respectively into the first roller 4 of circumference setting and the second roller 5 becoming circumference to arrange, some first rollers are arranged on a retainer, and some second rollers are arranged on another retainer 6, and the first roller and the second roller all can roll on retainer 6.Structure, the shape and size of the first roller and the second roller are identical.The movable chamber of roller is formed between first inner ring and the second inner ring, two retainers are placed on the both sides in the movable chamber of roller respectively, and be oppositely arranged, first roller and the second roller are arranged on after on two retainers respectively, the axis of the first roller and the axis angle in an acute angle of the second inner ring, the axis of the second roller and the axis angle in an acute angle of the second inner ring, the symmetry plane of some first rollers second inner ring relative to some second rollers is symmetrical arranged.Second inner ring is when the first inner ring rotates, and the first roller and the second roller rotate simultaneously.
