Abstract
The utility model relates to a bearing dismounting tool for dismounting a bearing on a coupling of a flywheel shell cover plate of a diesel engine. The tool comprises a connecting plate, wherein the bottom of the connecting plate is connected with a positioning block, thread holes are formed in the middle parts of the connecting plate and the positioning block and penetrate through the same, and tightening bolts are cooperatively arranged in the thread holes, the positioning block takes the shape of a bottle cover, and sleeves on the coupling at the flywheel end of the diesel engine when in use; two side of the connecting plate which are symmetrical with each other are respectively connected with the upper end of a pull rod through a bolt, the two pull rods are in the same length, the lower end of each pull rod is connected with a pull block, and the pull blocks are parallel to the connecting plate. According to the bearing dismounting tool for dismounting the bearing on the coupling of the flywheel shell cover plate of the diesel engine, the bearing can be dismounted from the coupling intactly, so that the economic cost is saved, and waste is avoided.
Description
Technical field
The utility model belongs to mechanical processing technique technical field, is specifically related to diesel engine and tears bearing instrument open.
Background technology
The bell housing cover plate that four cylinder Diesel engines are joined harvester need to be connected with flywheel end by shaft coupling, bearing, and when the assembling of bell housing cover plate goes wrong, need to be pulled down, because bearing and shaft coupling are interference fit, after bell housing cover plate is pulled down, bearing need to be pulled down from shaft coupling.Existing dismounting is exactly directly with iron hammer, bearing to be struck down, easily damages bearing and causes waste; In dismounting bearing process, also likely damage the shaft coupling of running in bearings, and bearing is difficult for removing.The utility model provides a kind of bearing instrument of tearing open, can be by bearing intact pulling down from shaft coupling, and bearing can be used again, avoids waste.
Summary of the invention
The problems referred to above that exist in order to solve the dismounting of diesel engine assembling process middle (center) bearing, the utility model provides a kind of instrument of tearing bearing for diesel engine open.
The bearing instrument of tearing open for the dismounting of diesel engine flywheel housing-plate shaft coupling upper bearing (metal), comprise connecting plate, the bottom surface of described connecting plate is connecting locating piece, and the middle part of connecting plate and the middle part of locating piece offer the screwed hole of perforation, coordinates to be provided with to tight a bolt in screwed hole; Described locating piece is bottle cap shape, and during use, cover is buckled on the bell housing cover plate shaft coupling of diesel engine; The symmetrical both sides of connecting plate are connecting respectively the upper end of pull bar by latch, two pull bars equal in length, and the lower end of every pull bar is connecting pulling block, and described pulling block is parallel to connecting plate.
Described connecting plate is rectangular slab, and the symmetrical both sides of connecting plate are respectively equipped with the contiguous block of the groove shape of evagination, and the contiguous block of every side is connecting the upper end of pull bar by latch; Described latch is opening latch, in the overhanging end of opening latch, is provided with split pin.
Described pulling block is rectangular block, and two corresponding side edge of pulling block are respectively equipped with the raised line raising up.
Useful technique effect of the present utility model is: when tearing bearing open, with open-end wrench, to tighting a bolt, 5 tighten, apply the effect of power by connecting plate 1 and 2 pairs of axle heads of locating piece, pull bar 3 drives pulling blocks 4, bearing inner race is imposed to the effect of power, and bearing 9 is pulled down.Connecting plate 1 is threaded hole, 5 matches with tighting a bolt; Pull bar 3 is connected with split pin 7 by latch 6 with connecting plate 1, and pull bar 3 can be to both sides opened with certain angle; On pulling block 4, with small stair and bearing 9 action of inners, bearing 9 is pulled down.The utility model can be pulled down from axle bearing 9 is intact, saves financial cost, avoids causing waste.

The specific embodiment
Below in conjunction with accompanying drawing, by embodiment, the utility model is further described.
Embodiment:
Referring to Fig. 1 and Fig. 3, the bearing instrument of tearing open for the dismounting of diesel engine flywheel housing-plate shaft coupling upper bearing (metal) comprises connecting plate 1, and the bottom surface of described connecting plate 1 is connecting locating piece 2, and locating piece 2 is bottle cap shape, during use, cover is buckled on the bell housing cover plate shaft coupling 8 of diesel engine.The middle part of the middle part of connecting plate 1 and locating piece 2 offers the screwed hole of perforation, coordinates to be equipped with to tight a bolt 5 in screwed hole.Referring to Fig. 2, connecting plate 1 is rectangular slab, and the symmetrical both sides of connecting plate 1 are respectively equipped with the projection of the groove shape of evagination, and the projection of every side is connecting the upper end of pull bar 3 by latch 6; Latch 6 is opening latch, is fitted with split pin 7 in the overhanging end of opening latch.Referring to Fig. 4, two pull bars 3 equal in length, the lower end of every pull bar 3 is connecting pulling block 4, and every pulling block is parallel to connecting plate 1.Described pulling block 4 is rectangular block, and two corresponding side edge of pulling block are respectively equipped with the raised line raising up.
During use, referring to Fig. 5, first by two pull bars 3 to both sides opened with certain angle, and locating piece 2 covers are buckled on the output of flywheel housing cover plate shaft coupling 8, again two pull bars 3 are drawn close to centre, then in 5 screwed holes that are screwed on connecting plate 1 and locating piece 2 that tight a bolt, make to tight a bolt 5 end contacts with the output of diesel engine flywheel housing-plate shaft coupling 8, continue to tight a bolt 5, two raised lines on pulling block 4 are contacted with the inner ring of bearing 9, now whole device is in stressed tensioning state, with open-end wrench, continue 5 effects that apply power that tight a bolt, raised line band dynamic bearing 9 on two pulling blocks 4, bearing 9 is upwards mentioned slowly, bearing 9 disassembles from diesel engine flywheel housing-plate shaft coupling 8 the most at last.
