Abstract
The utility model provides a split cylindrical roller bearing, which aims to solve the problem that a bearing is inconvenient to dismount. The split cylindrical roller bearing is formed by assembling cylindrical rollers in two sets of half outer rings, half inner rings, half cage covers and half cage seats, and comprises an axial positioning bearing and a moving support bearing, wherein a front half clamp ring and a rear half clamp ring are mounted outside the two sides of the two half inner rings respectively; the end parts of the front half clamp ring and the rear half clamp ring are fastened by four groups of screws and a washer; the half cage seats are fixedly linked through two sets of combined connecting plates by screws and a washer, and the ellipticities of the internal and the external diameters of the half cage seats are smaller than or equal to 0.3mm; and a hoisting threaded hole is formed on the split surface at the joint part of the two half inner rings and assists in mounting the two half inner rings. The split cylindrical roller bearing can be quickly and correctly mounted.
Description
Technical field
The utility model relates to roller bearing, is specifically related to a kind of subdivision roller bearing.
Background technique
When solid box is packed major axis into, could assemble after the related components on the axle need being pulled down, if it is super-huge part is just more inconvenient, time-consuming and cause production loss.
Summary of the invention
The utility model provides a kind of subdivision roller bearing to satisfy above-mentioned operating mode.The subdivision roller bearing is by two cover semi outer rings 1 of subdivision vertically, half inner ring 5, half retainer lid 3, partly keeps stand 6 that cylindrical roller 2 is assembled in wherein constituting; Described subdivision roller bearing comprises the axially locating bearing and the block bearing that moves about; Front card collar 10 and rear card collar 12 respectively are installed outside the both sides of two and half inner rings 5 of described subdivision roller bearing, respectively that the end of front card collar 10 and rear card collar 12 is fastening with four groups of screws 4 and packing ring 11.
The described stand 6 of partly keeping adopts connecting plate 7 that two covers join work by screw 8 and packing ring 9 fastening connections, and internal diameter and external diameter ovality are no more than 0.3mm.
Offer the lifting tapped hole on the described two halves inner ring 5 binding site split surfaces.
Usefulness of the present utility model is: realization is quick, accurate installs, and is mainly used in to slowly run or heavily loaded rotary part.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is a subdivision roller bearing sectional view;
Fig. 2 is that the subdivision roller bearing is along the A_A sectional view.
Among the figure: semi outer rings 1, cylindrical roller 2, half retainer lid 3, screw 4, half inner ring 5, partly keep stand 6, connecting plate 7, screw 8, packing ring 9, front card collar 10, packing ring 11, rear card collar 12.
Embodiment
The subdivision roller bearing comprises the axially locating bearing and the block bearing that moves about for whole axle has been equipped with, for equipment has been simplified component.
As shown in Figure 1, the subdivision roller bearing is by two cover semi outer rings 1, half inner ring 5, the half retainer lid 3 of subdivision vertically, partly keeps stand 6 that cylindrical roller 2 is assembled in wherein constituting; Front card collar 10 and rear card collar 12 respectively are installed outside the both sides of two and half inner rings 5, respectively half end that tightens circle 10 and rear card collar 12 are clamped (see figure 2) with four groups of screws 4 and packing ring 11; On two halves inner ring 5 binding site split surfaces, offer the lifting tapped hole, during 5 assemblings of two and half inner rings, can utilize the auxiliary installation of lifting tapped hole, after front card collar 10 and rear card collar 12 clamp, will inevitably there be micro gap in the binding site split surface, shows that two and half inner rings 5 assemble successfully.Two halves keep stand 6 to adopt two covers to join the connecting plate 7 usefulness screws 8 and the packing ring 9 fastening connections of work, back internal diameter and external diameter ovality are installed are no more than 0.3mm.
