Abstract
A dismantling device of a radial thrust bearing taper sleeve consists of a jack, a dismantling plate, a plurality of dismantling screws and a supporting plate, and is characterized in that the dismantling screws are connected between the dismantling plate and the supporting plate, the dismantling plate is connected to the taper sleeve, and the jack is mounted in a space between the dismantling plate and the supporting plate. The dismantling device of the radial thrust bearing taper sleeve is used for dismantling the taper sleeve, realizes dismantling operation for maintenance smoothly, increases repair precision and work efficiency and eliminates the problem of failure of dismantling, and dismantling strength and force of the dismantling device are strengthened greatly,.
Description
Technical field
The utility model belongs to flight-line maintenance equipment, is a kind of provision for disengagement of radial thrust bearing tapered sleeve.
Background technology
Rotor main shaft bearing tapered sleeve on the KTC80 filament cutter generally adopts interference fit to be connected cutter and rolls on the main shaft as the installation sleeve of conical bore self-aligning roller bearing 3122, as shown in Figure 1, approaches because of it is empty, and its dismounting is a difficult point during rotor is repaired.Directly the drawing tapered sleeve can occur because lifting surface area causes the situation of device failure for a short time.Though be reserved with the screw thread of assembling and disassembling dish when repairing dismounting on the tapered sleeve, owing to cooperate closely, and running time is longer, uses the dismounting of SKF specialty bearing extractor, and afterburning to the center bolt distortion, the screw thread damage all can not be become flexible tapered sleeve.
The utility model content
The purpose of this utility model provides a kind of provision for disengagement of radial thrust bearing tapered sleeve, guarantees in KTC80 filament cutter overhaul process, and when not damaging filament cutter main shaft and tapered sleeve precision, again can be smooth safely, like a cork the main shaft tapered sleeve is disassembled.
The purpose of this utility model realizes by following technical solution:
A kind of provision for disengagement of radial thrust bearing tapered sleeve, form by jack, dismounting dish, dismantling screw and gripper shoe, it is characterized in that: be connected between dismounting dish on the tapered sleeve and the gripper shoe and be connected with many dismantling screws, the jack of packing into of the space between dismounting dish and the gripper shoe.
The screw that a plurality of connection dismantling screws are arranged on the described dismounting dish, dismantling screw one end and dismounting dish are combined as a whole by screw thread, and the other end is connected with gripper shoe by bolt.
Carry out the tapered sleeve dismounting with the provision for disengagement of radial thrust bearing tapered sleeve described in the utility model, dismounting rigidity and removal force strengthen significantly, repair demolition work is smooth, has improved repairing precision and operating efficiency, does not occur the problem that can't dismantle again.
Description of drawings
Fig. 1 is existing filament cutter rotor main shaft and bearing tapered sleeve connection diagram.
Fig. 2 is a structural representation of the present utility model.
1-main shaft among the figure, 2-tapered sleeve, 3-dismounting dish.The 4-dismantling screw, 5-jack, 6-gripper shoe.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
The utility model has a dismounting dish, screw thread when utilizing the repairing dismounting of reserving on the tapered sleeve, by the installation of combining closely of internal thread on the dismounting dish and tapered sleeve, there are a plurality of screw installing/dismounting screw rods that they are connected as a single entity on the dismounting dish, dismantling screw other end construction bolt, dismantling screw is combined closely by bolt and gripper shoe, the jack of packing into of the space between dismounting dish and gripper shoe.When needing the dismounting tapered sleeve, the dismounting dish is contained on the tapered sleeve, jack is placed between main shaft and the gripper shoe, starts jack and just tapered sleeve can be unloaded.
Embodiment
So that four screws to be arranged on the dismounting dish is example, and supporting corresponding four length are 250mm, and diameter is dismantling screw and gripper shoe of 16mm, and gripper shoe is that 45 steel are made, thickness 20mm, and they are combined into the provision for disengagement of radial thrust bearing tapered sleeve.Select existing five tons of fluid pressure type jack for use; At first the dismounting dish is installed in before the dismounting on the main shaft tapered sleeve and fastening, four screw rods is screwed in remove in the valve snail holes and balancedly fastening then; Gripper shoe is installed on the terminal bolt of also putting on equably of dismantling screw; Then five tons of fluid pressure type jack balances are placed between filament cutter rotor main shaft 1 and the gripper shoe 6, and fluid pressure type jack axis and rotor main shaft are kept point-blank, again the bolt balance of the dismantling screw end on the gripper shoe is locked equably, make that whole provision for disengagement is in evenly, the balance locking state.At this moment just can use the pressurized handgrip of five tons of fluid pressure type jack, equilibrium is separated main shaft with filament cutter rotor main shaft bearing tapered sleeve lentamente, and whole unloading process is easily smooth.
Claims (2)
1. the provision for disengagement of a radial thrust bearing tapered sleeve, form by jack, dismounting dish, dismantling screw and gripper shoe, it is characterized in that: be connected between dismounting dish on the tapered sleeve and the gripper shoe and be connected with many dismantling screws, the jack of packing into of the space between dismounting dish and the gripper shoe.
2. the provision for disengagement of the described radial thrust bearing tapered sleeve of claim 1 is characterized in that: the screw of a plurality of connection dismantling screws is arranged on the dismounting dish, and dismantling screw one end and dismounting dish are combined as a whole by screw thread, and the other end is connected with gripper shoe by bolt.
