Description
Technical field
The application relates to airborne vehicle manufacturing technology field, particularly about the dismantling device and the assembly and disassembly methods of the aviation oscillating bearing on the aircraft actuation mechanism.
Background technology
At present, along with the develop rapidly of Computerized Numerical Control processing technology, airplane design technology, be widely used on the oscillating bearing actuation mechanism aboard.Oscillating bearing is a kind of sliding bearing of special construction.Its structure is simpler than rolling bearing, and it mainly is made up of an inner ring and the outer ring by Internal Spherical Surface by spherical outside surface, can bear bigger load.Oscillating bearing generally is used for lower oscillating motion of speed and low-speed rotation, also can make banking motion in the certain angle scope, when bolster and axle housing hole decentraction are big, and still can operate as normal.Used at key positions such as undercarriage, spoilers widely at the aviation field oscillating bearing.During the mounting spherical sliding bearing, suggestion is used to install and is used towards cap or one section tubing, should avoid directly knocking race ring.Definitely can not transmit installing force by sliding surface.Along with the increase of bearing size, the required power of bearing is installed also sharply increases, thereby usually bigger bearing can not be installed under cold state.Generally can install by the mode of heating bearing or bearing block.Removal force required during dismounting should be added on the lasso to be removed all the time.
This has just brought a new problem---the dismounting problem of oscillating bearing.At present the plain bearing that extensively is suitable for of other field generally uses the bearing drawbench to dismantle, but drawbench only is applicable to from axostylus axostyle and dismantles small size bearing, can't be used to dismantle oscillating bearing, more can not be used to install bearing.If need change to the oscillating bearing on big parts of aircraft or the complete machine, special site environment can't the working pressure machine etc. other equipment do not allow to knock yet, otherwise may cause the parts distortion even scrap.Therefore, need design a kind of new instrument and carry out the dismounting of oscillating bearing, to satisfy the needs of change in design and aircraft maintenance, easily and fast, safety oscillating bearing is dismantled and is installed.
Summary of the invention
The purpose of this utility model has been to provide a kind of instrument that removes and installs of oscillating bearing and has removed and installed method.By this instrument, can on parts or complete machine, dismantle and install easily and fast oscillating bearing, whole unloading process need not forcing press, do not have shock loading, and is safe and reliable.
The application's design philosophy is oscillating bearing to be extracted or is pressed into bearing block by the screw thread principle.The instrument that removes and installs of oscillating bearing, oscillating bearing contains bearing outer ring and bearing inner race, the described instrument that removes and installs is made up of harness cord bolt, pulling nut, supporting component and bearing briquetting, the bearing briquetting is a rigid structure that symmetrical presser feet is arranged, external diameter between the presser feet is less than the bearing outer ring external diameter, there is bolt hole at the center of bearing briquetting, and supporting component is made up of supporting seat and movable cushion block, and there is bolt hole at the center of supporting seat.
The internal diameter of bearing briquetting should be less than bearing outside diameter greater than the bearing inner race external diameter; The distance of two lip blocks should be greater than bearing outside diameter; The height of lip block should be greater than the height overall of bearing during dismounting; The height of lip block should be greater than the difference in height of bearing enclose end face during installation; Supporting seat is provided with central channel in the side up and down, and bolt hole is positioned at the center of central channel, to guarantee that two lip blocks and bolt are on the same line.
Adopt above-mentioned instrument to be to the installation method of oscillating bearing, at first oscillating bearing is placed on the installing hole of bearing block, the harness cord bolt sleeve is connected in the bolt hole of bearing briquetting, the presser feet of bearing briquetting is crimped on the surface of bearing outer ring, supporting component is placed the another side of the installing hole of bearing block, the other end of harness cord bolt passes the bearing centre hole successively, the centre bore of bearing block and the bolt hole of supporting component are spirally connected with the pulling nut, the bolt head of harness cord bolt is fixed, rotation pulling nut is crimped on oscillating bearing in the installing hole of bearing block under the active force of screw thread gradually.
Adopt above-mentioned instrument to be to the method for dismounting of oscillating bearing, the harness cord bolt sleeve is connected in the bolt hole of bearing briquetting, the presser feet of bearing briquetting is crimped on the surface of bearing outer ring, supporting component is placed the another side of the installing hole of bearing block, the other end of harness cord bolt passes the bearing centre hole successively, the centre bore of bearing block and the bolt hole of supporting component are spirally connected with the pulling nut, the cushion block symmetry of supporting component is crimped on the both sides of bearing block installing hole, the height of the cushion block of supporting component is greater than the height of oscillating bearing, the bolt head of harness cord bolt is fixed, rotation pulling nut withdraws from oscillating bearing under the active force of screw thread gradually in the installing hole of bearing block.
The application's beneficial effect is simple and reasonable, easy for operation, be not subjected to spatial constraints, can the enforcement of the condition of not opening wide fast, safety, the dismounting or the installation to oscillating bearing of no shock loading, can not cause damage, be specially adapted to use under special equipment and the particular surroundings other adjacent zeros parts.
Below in conjunction with the embodiment accompanying drawing, the application done describing in further detail.
