Abstract
The utility model relates to a bearing removal tool, include bolt, nut, sleeve, apron, round pin axle, carry the head, the bolt fastening on the apron, the nut is installed through the screw thread to the tip, is provided with the sleeve that can follow the bolt and remove between nut and apron, carries the head through round pin axle and cover connection, the round pin axle can free dismouting, conveniently carries the head and the bearing fit that is dismantled, carries the head along lapping a week evenly distributed everywhere. The utility model discloses the principle is simple, and convenient operation uses safe and reliable, realizes steady, safe the dismantling of bearing, guarantees to dismantle the safe, reliable of in -process bearing and installation base member and people.
Description
Technical field
A kind of extracting tool that this utility model is related to, especially a kind of extracting tool of bearing.
Background technology
Bearing, is a kind of important spare part in contemporary plant equipment, and its major function is supporting machinery rotary body, is reduced
Coefficient of friction in its motor process, and ensure its rotating accuracy.In being widely used in the mechanical reducers such as aviation, ship.Bearing
Dismounting carry out when being periodic maintenance, bearing replacing, be to ensure component stability reliability service, prevent bearing from relatively rotating, bearing
Interference fit is designed as between phase accessory, nip is generally larger, this will cause bearing removal difficulty big.Set as needed
Meter makes extracting tool, it is ensured that dismounting is safe and reliable, reduces the probability damaged to bearing and phase accessory.The one kind for using at present
Helicopter Transmission System bearing extractor is as shown in figure 1, main operational principle is to carry 10 to catch on the end ring to be dismantled
On one side, by the impulsive force of sleeve perseveration by bearing while lift, the another side of bearing is then lifted again, through making repeatedly
With the dismounting for finally realizing bearing, because the instrument only one of which carries head, can only single-point effect, extremely unstable, dismounting when easily
Cause the damage of bearing or bearing installing matrix, affect the reliability for using.
The content of the invention
This utility model purpose is to provide a kind of bearing extractor of dedicated reliable, makes the bearing can be with safe and reliable
Carrying out dismantle, it is to avoid bearing and matrix sustain damage, it is ensured that the reliability that product is used.
Concrete technical scheme of the present utility model is, bearing extractor include bolt, nut, sleeve, cover plate, bearing pin,
Head is carried, described is bolted on cover plate, and end is provided with nut by screw thread, being provided between nut and cover plate can edge
The sleeve of bolt movement, is carried head and is connected with cover plate by bearing pin, and bearing pin can conveniently carry head with the bearing being disassembled with disassembled and assembled freely
Coordinate, carry head and be uniformly distributed everywhere within one week along cover plate.Described sleeve outer surface is arc.
The impulsive force that sleeve is produced is distributed to four and is carried on head by this utility model by cover plate, it is ensured that edge during bearing removal
Circumference stress balance, unloading process is stable, reliable, it is to avoid bearing or matrix are caused to damage, sleeve adopts cambered design, easily holds
Tightly, make operation safer, more reliable, it is ensured that people, the safety of machine and reliability in unloading process.
Description of the drawings
Fig. 1 is traditional bearing extracting tool schematic diagram；
Fig. 2 is structural representation of the present utility model.
Specific embodiment
As shown in Fig. 2 bearing extractor includes bolt 1, nut 2, sleeve 3, cover plate 4, bearing pin 5, carries 6, it is described
Bolt 1 is fixed on cover plate 4, and end is provided with nut 2 by screw thread, and being provided between nut 2 and cover plate 4 can be along bolt 1
Mobile sleeve 3, is carried 6 and is connected with cover plate 4 by bearing pin 5, and bearing pin 5 can conveniently carry 6 with the axle being disassembled with disassembled and assembled freely
Cooperation is held, 6 is carried and is uniformly distributed everywhere within 4 one weeks along cover plate.The described outer surface of sleeve 3 is arc.
When in use, first carrying for bearing extractor 4 is caught on into the lower stop edge that to dismantle bearing, 4 will be carried and passed through
Bearing pin 5 is fixed on pressing plate 4, and the dismantlement work of bearing is then completed by lifting the impulsive force of sleeve generation repeatedly upwards.
