Abstract
The utility model provides a simple bearing outer ring dismounting device, which comprises a screw rod (1), a supporting seat (2), an adjusting bolt (3), a limiting plate (4) and a claw (5); the screw rod (1) is in threaded connection with the supporting seat (2), the limiting plate (4) is arranged between the supporting seat (2) and the bearing outer ring, and the adjusting bolt (3) and the pulling claw (5) are fixed on the limiting plate (4). The utility model discloses the purpose is solved and is dismantled the difficult problem of bearing inner race, can carry out effective swift dismantlement to different radial bearing inner races in limited space to can guarantee to avoid the damage of bearing inner race. The casing deformation caused by the fact that the bearing outer ring is knocked violently in the development stage of the transmission is avoided, and therefore the development cost of a company is reduced to the maximum degree.
Description
Technical Field
The utility model relates to a mechanical dismantlement technical field, in particular to simple and easy bearing inner race dismounting device.
Background
Assembling in earlier stage and experimental the reprocessing in-process of having developed a section derailleur, the condition that need dismantle the bearing all can appear, because the derailleur belongs to the development stage, does not have special bearing outer lane extracting tool, can only strike the unilateral dismantlement of bearing outer lane through violence, very easily causes the casing to warp to lead to a large amount of finishing impression casing utilization ratio step-down, cause the great cost waste of company.
SUMMERY OF THE UTILITY MODEL
The utility model provides a simple and easy bearing inner race dismounting device, its purpose is solved and is dismantled the difficult problem of bearing inner race, can carry out effective swift dismantlement to different radial bearing inner races in limited space to can guarantee to avoid the damage of bearing inner race. In order to achieve the purpose, the embodiment of the utility model provides a simple and easy bearing inner race dismounting device for dismantle multiple size bearing inner race, including screw rod, supporting seat, adjusting bolt, limiting plate, claw.
The screw rod is sleeved in the supporting seat and connected with the limiting plate.
The middle of the limiting plate is provided with threads, and the threaded holes are matched with the screw rods.
The adjustable limiting plate is characterized in that long holes are formed in two sides of the limiting plate, two pulling claws are arranged on the limiting plate and can move on the limiting plate, and the pulling claws are provided with threads which are matched with the adjusting bolts.
The above technical scheme of the utility model has following beneficial effect:
the utility model provides an among the dismounting device, the pulling claw can remove on the limiting plate to satisfy the bearing inner race dismantlement of multiple different diameters. The utility model discloses a to the rotation of screw rod, drive the claw under the vice effect of screw thread transmission and carry the bearing inner race and draw out. The utility model discloses a "U" type supporting seat has guaranteed the stability of dismantlement process and has extracted the atress homogeneity of bearing inner race, and then has avoided the damage of bearing inner race.

Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.
The utility model discloses mainly be to when dismantling derailleur bearing inner race, guarantee bearing inner race ability reutilization in the time of quick detachable, provide a bearing inner race dismounting device.
As shown in fig. 1, the embodiment of the utility model provides a this bearing inner race dismounting device includes screw rod 1, supporting seat 2, adjusting bolt 3, limiting plate 4 and claw 5.
The upper end of the screw rod 1 is in clearance fit with the supporting seat 2, and the screw rod 1 is limited and can be suspended on the supporting seat 2;
the head of the upper end of the screw rod 1 is connected with a tool wrench and can rotate freely;
the lower end of the screw rod 1 is in threaded connection with the limiting plate 4, and the limiting plate 4 can be lifted upwards by rotating the screw rod 1 clockwise;
the lower end of the supporting seat 2 is in contact with the fixed surface, the contact surface is two semicircles, the bearing is stressed uniformly when the bearing is disassembled, and the bearing outer ring is prevented from being inclined in the process of disassembling the bearing outer ring;
the middle of the limiting plate 4 is a threaded hole, is in threaded connection with the screw rod 1 and can move up and down on the screw rod 1 through threads;
the two ends of the limiting plate 4 are rectangular holes, and the adjusting bolt 3 can be suspended in the rectangular holes of the limiting plate 4;
the adjusting bolt 3 is in clearance fit with the limiting plate 4 and is in threaded connection with the pusher dog 5, and the pusher dog 5 is fixed at the position of the limiting plate 4 through rotation of the adjusting bolt 3;
the upper end of the pusher dog 5 is in clearance fit with the rectangular hole of the limiting plate 4, and can move left and right in the rectangular hole of the limiting plate 4 to adjust the distance between the two pusher dogs and meet the requirements of different radiuses for disassembling the outer ring of the bearing;
as shown in fig. 1, the utility model discloses during the use, at first, unscrew adjusting bolt 3, adjust two claws 5 distances of pulling out, will pull out claw 5 and be located bearing inner race below, secondly screw up adjusting bolt 3, with limiting plate 4, pull out claw 5, adjusting bolt 3 is fixed, then arrange the stationary plane in with supporting seat 2, put into the supporting seat centre bore with screw rod 1 simultaneously, it is fixed through threaded connection with limiting plate 4, utilize spanner constantly rotatory screw rod 1 at last, drive under the vice effect of screw thread transmission and pull out claw 5, limiting plate 4, adjusting bolt 3 together follows axial direction rebound, finally extract the bearing inner race.
The utility model provides a bearing inner race dismounting device can effectual, swift dismantlement bearing inner race to guarantee that bearing inner race does not receive the damage, be almost zero to the casing damage, the effectual derailleur casing who is the development in earlier stage the cost is reduced.
The foregoing is a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
