Abstract
The utility model discloses a bearing puller, and belongs to disassembling tools in the field of machines. The bearing puller comprises a traction lead screw, transverse rod pieces and vertical rod pieces, wherein the transverse rod pieces and the vertical rod pieces are mutually related. The traction lead screw penetrates through an unthreaded hole in the middle of a lower cross beam to be located on a nut cap at the lower end of the lead screw, and then penetrates through a threaded hole in the middle of an upper cross beam to be connected with the upper cross beam in a threaded mode. The two ends of the upper cross beam are respectively connected with a supporting rod in a sleeved mode, and the lower end of each supporting rod is provided with an adjusting screw. The two ends of the lower cross beam are respectively provided with a pull rod in a sleeved mode, the lower portions of the two pull rods are provided with a spacing adjusting mechanism, and the lower ends of the pull rods are provided with pull hooks which stretch outwards. By means of the bearing puller, the outer circle of a bearing in a shell hole can be disassembled simply, conveniently, quickly and safely, the labor intensity is relieved and the working efficiency is improved.
Description
Technical field: the utility model belongs to a kind of extracting tool of mechanical field.
Background technology: often have the dismounting of bearing in flight-line maintenance, conventional way is to knock with cushion block, and the radial ball bearing being arranged on axle can pull down with tri-paw puller, or depress next with forcing press.For being arranged on bearing in housing bore, particularly taper roll bearing is after taking off axle, and its bearing outer ring is knock or use oxygen cutting all easily to damage parts and sealing, there is no again practical chest expander, is a kind of work of the effort of taking a lot of work.
Summary of the invention: the purpose of this utility model is a kind of bearing chest-developer of design, and the bearing outer ring in housing bore can easily be taken off.The purpose of this utility model is achieved in that a kind of bearing chest-developer, comprises traction table lead screw and is mutually related horizontal, vertical bar.Traction table lead screw, through the unthreaded hole at sill middle part, makes it to drop on the nut of leading screw lower end, then is threaded with entablature through the screwed hole at entablature middle part.The each support bar of ining succession that overlaps in entablature two ends, there is adjustment screw each support bar lower end; The each pull bar of ining succession that overlaps in sill two ends, distance regulating mechanism is arranged at two pull bar bottoms, and there is respectively the drag hook stretching out laterally pull bar lower end.The distance regulating mechanism of pull bar bottom is to fix respectively a screw rod with right-hand thread and left-hand thread in two pull bar inner sides, and respectively with two, adjusting sleeve pipe two ends screw flight is connected.
The simple and efficient safety again of bearing outer ring in this bearing chest-developer dismounting housing bore, reduces labor intensity, and has improved operating efficiency.
Accompanying drawing explanation: the structural representation of Fig. 1 bearing chest-developer.Fig. 2 be represent that support bar and top rail beam casing connect to view.
The specific embodiment: be further described below in conjunction with accompanying drawing.
As shown in drawings, a kind of bearing chest-developer, comprises traction table lead screw and is mutually related horizontal, vertical bar.Traction table lead screw 1 is through the unthreaded hole at sill 5 middle parts, make it to drop on the nut of leading screw lower end, be threaded with entablature through the screwed hole at entablature 3 middle parts again, the each support bar 2 of ining succession that overlaps in entablature two ends, there is height adjustment screw 4 each support bar lower end, is used for regulating the length of support bar.Distance regulating mechanism is arranged at each 6, two pull bar bottoms of a pull bar of ining succession of overlapping, sill two ends, and this distance regulating mechanism is to fix respectively a screw rod 8 that has right-hand thread and left-hand thread in two pull bars inner sides, and respectively with two, 9 two ends of adjusting sleeve pipe screw flight is connected.Rotating casing can change amount pull bar spacing, make it to hook reliably split tiltedly another part.There is respectively the drag hook 7 stretching out laterally pull bar lower end.By they sup-port, on housing, the drag hook of pull bar hooks bearing outer ring, and rotational lead screw can pull out bearing outer ring.
