Abstract
The utility model discloses a universal bearing extractor, and belongs to bearing maintenance tools in practical production practice. The universal bearing extractor mainly comprises a pneumatic system, a control button, a guide rail and a shaft bracket. When in disassembling, a chuck holder is adjusted to drive a chuck to move axially on the guide rail to the position of a bearing, and is fixed by a locking device; the chuck is adjusted to a proper distance to ensure that the chuck is tightly clamped with the end surface of the bearing; nuts on the chuck holder is adjusted and fastened to realize the adjusting and fixing of the height position of the center of the chuck; and the disassembling power is provided by the pneumatic system, the axial movement of the bearing is limited by the chuck, and a piston rod pushes out a shaft from the bearing to realize the separation of a shaft and the bearing. The universal bearing extractor has the advantages that the traditional manual disassembling is replaced by the pneumatic system disassembling, and the disassembling force is stable, uniform, and efficient.
Description
Technical field
The utility model relates to general shaft bearing replacer, is the bearing maintenance tool in a kind of actual production practice.
Background technology
Bearing is one of component standards spare of extensive use in the modern machine, needs after the inefficacy to change.Axle belongs to interference fit with cooperating of bearing, owing to for a long time with causing having between axle and bearing lubricating oil absorption or the impurity phenomenon that bonds, or machinery is long placed in phenomenons such as need not causing the dead or aging distortion of axle of rust, so change relatively difficulty of dismounting, at present domestic application is the three-pawl type chuck more widely, and its shortcoming is the easy damaged axle, fixing not firm cause breaking off relations cause engineering accident, the rigid bearing position is difficult for grasping, and easily makes the bearing spallation if grab at bearing outer ring.For solving the difficult problem in this flight-line maintenance, research and develop a kind of new device and can realize axle and bearing effective separation, not only avoided the problem of the aspects such as axle damage that traditional dismounting mode may bring, greatly improve enterprises production efficiency simultaneously.
Summary of the invention
The purpose of this utility model is for solving the difficult dismounting problem of production practices axis and bearing, waste time and energy for overcoming the traditional bearing extracting tool, the turnover of the easy spallation ball of bearing is hurted sb.'s feelings and the defective such as the dismounting scope is single when dismantling, and the bearing disassembling device of a kind of high efficiency, safety, highly versatile is provided.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: general bearing disassembling device mainly is comprised of pneumatic system, gauge tap, chuck, chuck holder, guide rail and shaft tray.Pneumatic system, control button, guide rail and shaft tray all are fixed on the pedestal, and chuck is installed on the chuck holder, and the chuck holder bottom is fixed on the locking device, and locking device is installed on the guide rail.Adjust chuck holder during dismounting, make it drive chuck and on guide rail, move to vertically the bearing position, and fixed by locking device; Chuck is adjusted to suitable distance, guarantees chuck chucking bearing face; Adjust and the locking clamp plate rail on nut, realize the adjusting of chuck hub place height and position and fixing; Pneumatic system provides dismounting power, and chuck restriction bearing moves axially, and by piston rod axle is ejected from bearing and realizes that axle separates with bearing.Wherein, chuck is divided into upper and lower two parts, by changing the upper and lower two-part up and down distance of chuck to reach the purpose to Multiple Type bearing chucking.Be that face contacts between chuck and the bearing face, guarantee the security of unloading process; Chuck holder is used for two whole cutting threads of support of chuck for installing, and two nuts are installed on each support, places respectively the upper and lower two parts of chuck outer.When chuck be adjusted to suitable distance and adjust the chuck hub axle and the piston rod central shaft behind sustained height, screw lower nut, fixedly the position of chuck and make chuck chucking bearing face becomes the pneumatic system dismounting to the conventional manual dismounting, removal force is stable, evenly, efficient.

The specific embodiment
As shown in Figure 1, pneumatic system 1, control button 3 are fixed on the side plate of support 2, and guide rail 6 and shaft tray 7 are fixed on the base plate of support 2.Chuck 9 is installed on the chuck holder 5, and the bottom of chuck holder 5 is fixed on the locking device 4, and locking device 4 is installed on the guide rail 6.Regulated radial distance and the centre-height of chuck 9 by the nut on the chuck holder 5, and the fixing position of chuck 9.Locking device 4 is comprised of slide block, retaining ring and locking nut, and the slide block encapsulation is on guide rail 6.The base of chuck holder 5 is fixed on the slide block by 8 nuts, can move horizontally at guide rail 6.
As illustrated in fig. 1 and 2, axle 8 is placed on chuck 9 and the shaft tray 7 during dismounting; Adjust chuck holder 5 in the position on the guide rail 6 so that the distance between axle 8 and the piston rod 11 about 20cm.Adjust the nut of tightening on the locking device after complete and guarantee that chuck holder 5 is fixed on current location; Adjust the height of 9 times parts of chuck on chuck holder 5 by the nut on the chuck holder 5, make chuck 9 central shafts and piston rod 11 central shafts at sustained height; Part and 9 times partial distances of chuck are with chucking bearing 10 end faces on the radiai adjustment chuck 9; Start pneumatic system 1, press control button 3 and realize piston rod 11 F.F.s, when piston rod 11 proceeds near axle 8 end face soon, press that the worker advances button 3 so that piston rod 11 is close to axle 8 end faces, and slowly push ahead axle 8 with given speed, meanwhile bearing 10 is blocked in the chuck 9 and can not moves, and bearing 10 namely is removed, and should notice that the protection of bearing 10 prevents that it from dropping and causes unnecessary damage this moment; Press and stop button 3, take axle 8 away; Starting fast backward button 3 resets piston rod 11.
