Abstract
The utility model belongs to tools matched with a bearing dismounting machine for bearing dismounting, and particularly relates to a tool structure used for the bearing dismounting and used generally on bearing dismounting machines. A U-shaped notch is formed in a dismounting baffle. A door-shaped shell body corresponding to the U-shaped notch is fixedly connected on a position, on the outer side of the U-shaped notch, on the dismounting baffle in a perpendicular mode. The interior size of the door-shaped shell body is movably matched with the exterior size of a dismounted bearing. The width of the U-shaped notch is movably matched with the shaft diameter of a mounting shaft of the bearing to be dismounted. A lifting lug is fixedly connected on the top surface of the door-shaped shell body. The lower ends of symmetrical vertical faces of the door-shaped shell body are connected with plug pin inserting rings respectively. A plug pin is installed in each plug pin inserting ring in a matched mode. According to the tool structure used for the bearing dismounting and used generally on the bearing dismounting machines, the generality of the bearing dismounting machines can be increased, the serviceable range of the bearing dismounting machines is expanded, the use ratio of equipment is increased, and the overhaul of railway vehicles is convenient.
Description
Technical field
The utility model belongs to the frock with the matching used dismounting bearing of bearing removal machine, the tool structure of the general dismounting bearing of particularly a kind of bearing removal machine.
Background technology
260t torpedo type mixed iron car (being the torpedo jar) and common vehicle in maintenance process, change or revolve repair wheel to the time to carry out the wheel set bearing dismounting be wherein important step.At present, our employed bearing removal equipment is the bearing removal machine, but it can only be used to have the dismounting of the torpedo tank car wheel set bearing (nonstandard bearings D 352132X2/HAC3S1) and the TG hot-metal car bearing (self-aligning roller bearing 22328) of axle box, and also has the roller type RD2 wheel set bearing (197726 bearing) of nearly 70 C62 coal cars and steel scrap car in the eight iron and steel road self-provided cars, compare preceding two kinds of wheel set bearings in shape owing to there is not axle box, size can not be complementary with the size that the bearing dismantling machine is suitable for, so can't use this equipment dismounting bearing, this brings difficulty for the maintenance of C62 vehicle.
Wheel to axle box bearing dismounting principle is: two actuation arm trailing wheels of bearing removal machine are fixing to axle journal place (bottom of axle box bearing), hydraulic stem props up spindle nose, use hydraulic action that whole bearing is pulled down the back then and check whether its technical performance meets instructions for use.Why the bearing removal machine that we use can only be used in the dismounting of thunder tank car wheel set bearing and TG hot-metal car bearing, reason is that the size of demountor actuation gear is according to the design bearing of torpedo tank car wheel to the tape spool case, and the RD2 that the C62 vehicle uses wheel is 197726 bearings to usefulness, cause not its size of tape spool case is used size range less than the bearing removal machine, so can't use.
Summary of the invention
The purpose of this utility model is to provide the tool structure of the general dismounting bearing of a kind of bearing removal machine, can increase the versatility of bearing removal machine, enlarges the scope of application of bearing removal machine, improves usage ratio of equipment, makes things convenient for the maintenance of rolling stock.
The purpose of this utility model is achieved in that the tool structure of the general dismounting bearing of a kind of bearing removal machine, on the dismounting baffle plate, the U-shaped breach is being set, vertical affixed and the corresponding door of U-shaped breach shape housing on the dismounting baffle plate in the U-shaped breach outside, the interior shape size of door shape housing and the appearance and size of dismounting bearing are movingly, the width of U-shaped breach and the diameter of axle of waiting to tear open the bearing installation shaft are movingly, affixed hanger on the end face of door shape housing, affixed respectively latch slotting ring cooperates latch is installed in the latch slotting ring in the lower end of door shape housing symmetrical facade.
The utility model is according to the use size of bearing dismantling machine, the U type tool structure of making a box-type for the right bearing of RD2 wheel (is equivalent to adorn a provisional axle box for wheel set bearing, thereby the size that makes it reaches the use size of bearing removal machine regulation), when needs dismounting bearing, extract latch earlier, frock sling be enclosed within on the spindle nose and with latch fixing after, again two actuation arm of bearing removal machine are stuck in the dismounting baffle plate outer end of frock, just can successfully dismantle down its bearing.After pulling down bearing, remove frock and can carry out bearing inspection operation procedure.
Making of the present utility model: the thick 345B steel plate of whole 36 ㎜ of employing is made, its inside dimension is than right bigger 0.15-0.20 ㎜ of bearing outside diameter of RD2 wheel, external dimensions equates with the working size of bearing dismantling machine, be 300 * 300 * 250 ㎜, opening part dress ∮ 20 * 300 ㎜ hex bolts are worked as the fixedly latch of usefulness; Workpiece sidepiece welding hanger is used for the driving lifting and uses.
The bearing removal machine is increased supporting frock, enlarged the versatility of this equipment, improved the utilization rate of existing equipment.The utility model utilization is convenient, practical, and effect is fine in the practice.
The utility model has increased the versatility of bearing removal machine, has enlarged the scope of application of bearing removal machine, has improved usage ratio of equipment, has made things convenient for the maintenance of rolling stock.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described, Fig. 1 is a main TV structure schematic diagram of the present utility model, and Fig. 2 is the right TV structure schematic diagram of Fig. 1, and Fig. 3 is the plan structure schematic diagram of Fig. 1.
The specific embodiment
The tool structure of the general dismounting bearing of a kind of bearing removal machine, as Fig. 1, Fig. 2, shown in Figure 3, on dismounting baffle plate 1, the U-shaped breach is being set, vertical affixed and the corresponding door of U-shaped breach shape housing 2 on the dismounting baffle plate 1 in the U type breach outside, the interior shape size of door shape housing 2 and the appearance and size of dismounting bearing are movingly, the width of U-shaped breach and the diameter of axle of waiting to tear open the bearing installation shaft are movingly, affixed hanger 3 on the end face of door shape housing 2, affixed respectively latch slotting ring 4 cooperates latch 5 is installed in latch slotting ring 4 in the lower end of door shape housing 2 symmetrical facades.Width ratio between the door shape housing 2 symmetrical facade inwalls waits to tear open the big 0.15-0.20mm of bearing outside diameter.The thickness of dismounting baffle plate 1 is 32-40mm.The length of door shape housing 2 is 214mm, and is wide and highly be respectively 300mm.
The utility model can be used for the dismounting of roller type RD2 wheel set bearing easily, thereby makes this equipment can be common to the dismounting of three kinds of wheel set bearings of our existing torpedo tank car, TG hot-metal car and C62 vehicle, and its serviceability is fine at present.
