Abstract
The utility model relates to a bearing unloading mechanism. The utility model is characterized in that the bearing unloading mechanism comprises an annular fixing body formed by butt joint of two semi-annular fixing bodies. Each of the inner part of the semi-annular fixing body is provided with a hydraulic oil cavity, and one end of the annular fixing body is uniformly distributed with plunger pistons along the radial direction. One end of the plunger piston extends into the inner part of the hydraulic oil cavity, and the other end extends out of the fixing body. The hydraulic oil motivates the plunger piston to produce axial force to act on a bearing. The annular fixing body in butt joint is adopted, which is convenient for installing and fixing the mechanism. The plunger piston adopts an external top form, and the end part of the bearing is under uniform stress, with the maximum force 48T, so the bearing can be easily and conveniently detached. The utility model has the advantages of simple structure, small size, and convenient operation.
Description
Technical field the utility model relates to a kind of instrument of dismantling bearing, particularly a kind ofly utilizes the hydraulicdriven Bearning mechanism that unloads.
Background technology when changing the flaker bearing, can make the dismounting of bearing very difficult because of producing corrosion between brearing bore and pedestal in grease preliminary treatment process equipment.A kind of way is destructive dismounting, with gas welding bearing is cut and removes, and bearing is scrapped, and causes serious waste; Also have on the roll mandrel relative with bearing to have oil groove, send into hydraulic oil by fuel feed hole, oil pressure applies radial load to bearing, and it is floated, thereby realizes the dismounting of bearing.The problem that this structure exists is: be subjected to the influence of surface roughness and tapering deviation, hydraulic oil leaks easily, and tension is too little, unbalance stress, so the dismounting of bearing is still relatively more difficult.
The summary of the invention the purpose of this utility model is to provide a kind of Bearning mechanism that unloads quickly and easily.Concrete solution of the present utility model is: unload Bearning mechanism and comprise the annular fixed body that is formed by two semi-round ring shape fixed body butt joints, hydraulic fluid chamber is all arranged in the semi-round ring shape fixed body, one end of annular fixed body radially is evenly distributed with plunger, one end of plunger stretches in the hydraulic fluid chamber, the other end stretches out outside the fixed body, hydraulic oil is sent in the oil pocket, promotes plunger and makes it apply axial force to bearing inner ring, reaches the purpose of unloading lower bearing.The endoporus of annular fixed body is a taper hole.
Characteristics of the present utility model are: adopt dock annular fixed body, be convenient to installing and fixing of this mechanism; The outer top of plunger form, the bearing end is stressed evenly, and maximum, force can reach 48T, can unload lower bearing easily; Simple in structure, volume is little, and is easy to use; The taper hole of fixed body is identical with the tapering of axle, to the bearing application of force time, fixed body is oppositely moved.
Description of drawings Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that the A of Fig. 1 is to schematic diagram.
Schematic diagram when Fig. 3 works for the utility model.
The specific embodiment is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1, 2, the utility model is to be formed by 1 butt joint of two semi-round ring shape fixed bodies, and its joint is fixedly connected with bolt 2.The inside of semi-round ring shape fixed body has hydraulic fluid chamber 3, is connected with hydraulic system by oil connection 4.The end of fixed body is provided with sealing ring 7 along circumferentially being evenly equipped with the plunger hole 5 that is connected with hydraulic fluid chamber between plunger 6 in the hole and the plunger hole, and an end of plunger stretches in the hydraulic fluid chamber, and the other end stretches out outside the fixed body.The endoporus of annular fixed body is a taper hole 8.During use, as shown in Figure 3, two semi-round ring shape fixed bodies are fixed on the axle 10 of roll 9, plunger contacts with bearing inner ring, and in hydraulic oil entered into the fixed body oil pocket, plunger applied axial force to bearing inner ring, and itself and axle are separated, and unloads lower bearing.The utility model also can with the prior art acting in conjunction, promptly apply radial load to bearing inner ring by oil groove and the fuel feed hole of on axle, opening, unload lower bearing more like a cork.
Claims (2)
1, a kind of Bearning mechanism that unloads, it is characterized in that it comprises the annular fixed body that is formed by two semi-round ring shape fixed body butt joints, hydraulic fluid chamber is all arranged in the semi-round ring shape fixed body, one end of annular fixed body radially is evenly distributed with plunger, one end of plunger stretches in the hydraulic fluid chamber, the other end stretches out outside the fixed body, and hydraulic oil promotes plunger makes it produce responsive to axial force on bearing.
2, the Bearning mechanism that unloads according to claim 1, the endoporus that it is characterized in that the annular fixed body is a taper hole.
