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.
Model utility content
The purpose of this utility model is to provide a kind of double-row conical aligning heavy load sliding bearing joint shaft bearing and roller bearing combined.
The technical scheme in the invention for solving the technical problem is: 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 beneficial effects of the utility model are: the double-row conical aligning heavy load sliding bearing that the utility model provides, 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.
