Description
Technical field
The utility model belongs to crusher technical field, is related to a kind of bearing dismounting tool.
Background technology
According to equipment rebuilding standard, when overhaul crusher must dismounting crusher hammer axle bearing into shape, it will have a direct impact on equipment
Service efficiency and using unit economic benefit.Existing common practice is that dismounting bearing mostly uses greatly mode of heating, makes axis
It holds heat expansion and increases gap to extract bearing, heating the process of bearing may cause bearing material to change, to influence its machinery
Performance.It is to pound by getting rid of hammer strength and hit bearing using rule is tapped, so that bearing inner race and axle sleeve is disengaged and easy to disassemble, but taps
Shi Rongyi, which makes vehicle unbalance stress, may damage bearing, cause damages.It is to use specific purpose tool using rule is pulled out, dismantles axis respectively
The inner ring and outer ring held, under normal circumstances puller dismounting when need rotating handle that bearing is made slowly to pull out, this method to draw
The requirement of tool is higher, if puller is unable to the centre bore of aiming axis, is easily damaged bearing, drag hook is also easy to try to shirk responsibility.Based on this,
It is badly in need of proposing that one kind is simple in structure at present, it is easy to use, it is capable of the disassembling fixture of safe and reliable dismounting crusher hammer axle bearing.
Utility model content
The purpose of this utility model is to provide a kind of bearing dismounting tool, solves and is dismantled in existing crusher hammer axle bearing
It is middle to there is the problem of dismounting difficulty is big, and reliability is not high, accessory is easily damaged.
The technical scheme adopted is that a kind of bearing dismounting tool, the disassembling fixture includes and bearing the utility model
The inner ring of the wire tray to match, the wire tray is equipped with screw thread corresponding with bearing expansion sleeve, and the outer ring of wire tray offers keyway.
The principle of the technical program is, when bearing removal, the screw thread and bearing expansion sleeve the fastening lock that are equipped with using wire tray
Tightly, size reduces after bearing swelling cover locking, becomes larger with bearing clearance, and bearing is easy to extract naturally, avoids strength and dismantles
Damage bearing.
The utility model is also characterized by：
Further, wire tray internal diameter is 380mm, outer diameter 400mm, thickness 30mm.
Further, keyway is opened in the outer ring of wire tray at equal intervals.
Further, the radial depth that keyway opens up is 20mm, the consistency of thickness of the thickness opened up and the wire tray.
The utility model has the beneficial effects that in the dismounting of crusher hammer axle bearing, in wire tray and bearing expansion sleeve
Under locking effect, it is easy to realize bearing removal, reduce personnel labor intensity, enhance reliability and safety when dismounting
Property, while avoiding the Bearing fittings in dismounting and being damaged；It designs and produces simply, operation is flexible, has higher operable
Property and practical value.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of bearing dismounting tool of the utility model；
Fig. 2 is a kind of structural schematic diagram of the bearing dismounting tool of the utility model in dismounting.
In figure, 1. bearing outer rings, 2. bearing inner races, 3. rolling elements, 4. bearing expansion sleeves, 5. wire trays, 6. screw threads, 7. keys
Slot.
Specific implementation mode
The utility model is described in detail with reference to the accompanying drawings and detailed description, but the utility model and unlimited
In these modes.
A kind of bearing dismounting tool is suitable for crusher hammer axle bearing and dismantles, as shown in Figure 1, the bearing outer ring 1 of bearing is logical
It crosses rolling element 3 and slidably connects bearing inner race 2, bearing inner race 2 is sleeved on bearing expansion sleeve 4, and bearing is real by bearing expansion sleeve 4
Existing axial restraint.
Disassembling fixture includes the wire tray 5 to match with bearing, and the inner ring of wire tray 5 is equipped with corresponding with bearing expansion sleeve 4
Screw thread 6, wire tray 5 by one end of screw thread 6 and bearing expansion sleeve 4 be flexibly connected, 5 internal diameter of wire tray be 380mm, outer diameter 400mm,
Thickness is 30mm.
The outer ring of wire tray 5 offers 8 keyways 7 at equal intervals, and the radial depth that keyway 7 opens up is 20mm, the thickness opened up
With the consistency of thickness of wire tray 5.
When bearing removal, as shown in Fig. 2, wire tray 5 is screwed on the bearing expansion sleeve 4 of crusher hammer axle bearing, clockwise
Keyway is tapped, the screw thread fastening force locking bearing expansion sleeve 4 being equipped with using wire tray 5.Size subtracts after bearing expansion sleeve 4 is locked
It is small, become larger with bearing clearance, bearing is easy to extract naturally, avoids strength dismounting damage bearing.
Under the locking effect of wire tray and bearing expansion sleeve, it is easy to realize bearing removal, not only reduce personnel's labour
Intensity enhances reliability when dismounting and safety, while avoiding the Bearing fittings in dismounting and being damaged.
