Description
Technical field
The present invention relates to parts to dismount technical field, more specifically, more particularly to a kind of screw thread class part, especially beautiful
State FALK（Fu Ke）The device of monoblock type speed reducer middle (center) bearing retaining ring.
Background technology
To improve the precision of speed reducer（Concentricity equally accurate of the gear centre away from, bearing socket）, ensure the excellent of speed reducer
Good behavior in service, in conjunction with the production technology characteristic of lathe, the FALK in the U.S.（Fu Ke）Box body of speed reducer is designed as monoblock type, such as schemes
1, shown in 2, in figure respectively marked as：1- input shafts, oil sealing × 2 2-, 3（11）Bearing locking ring（Input shaft）, 4- retaining rings（It is defeated
Enter axis）, 5- high gears, 6- bearings, 7- output shafts, 8（16）Bearing locking ring（Output shaft）, 9- boring covers（Output shaft）, 10- it is low
Fast gear, 12- input shafts（Boring cover）, 13- bearings（Input shaft）, 14- hexagon socket cap head screws, 15- bearings, 17- retaining rings,
18- keyways, oil sealing × 2 19-, 20- hexagon socket cap head screws, 21- box body of speed reducer, hole for hoist × 8 22-.
The bearing of this speed reducer is to fix and adjust working clearance, bearing locking ring by bearing locking ring（See Fig. 4,
5、6、7）It to embed screw thread type, and prevents bearing locking ring from rotating using the fastening means of " screw thread dislocation ", and then reaches axis
The purpose for the axially position held；Since the speed reducer is driven for parallel axis helical teeth, the axial force that high low speed bearing is subject to is larger；Again
In addition when equipment operation high, low speed axis thermal expansion force；And to the axial impact force of speed reducer high-speed bearing when motor start and stop
To the impact force of speed reducer low speed bearing when changing with machine utilization.All these axial forces are transferred to axis by high low speed bearing
It holds in retaining ring, the screw thread at bearing locking ring " screw thread dislocation " is made to be permanently deformed（See Fig. 3）, cause bearing locking ring firm
Admittedly lock on reduction box (see Fig. 1:It is bearing of input shaft retaining ring and code name be 8,16 is output shaft bearing that code name, which is 3,11,
Retaining ring）, therefore, the first big technological difficulties that bearing locking ring is the overhaul of the equipments how are dismantled, for this technological difficulties,
Take solutions several so now.
First method：When dismantling at the scene, retaining ring is fastened on bearing locking with four hexagon socket cap head screws
On ring, hammer force then is imposed in retaining ring groove, the hammer force F acted in the outer circle of retaining ring passes through interior hexagonal cylindrical
Head screw is transmitted on bearing locking ring, and bearing locking circumferential direction outward turning transfers to reach dismounting purpose（See Figure 10,11）.But due to only
It moves back ring to connect using hexagon socket cap head screw with bearing locking ring, and between socket cap and retaining ring is transition cooperation, when making
When dismantling bearing locking ring with hammering retaining ring groove, the hexagon socket cap head screw neck nearest from hammer point is cut at first
Impact is cut, is broken first by after multiple shearing impact power, it is then close from hammer point time, slightly remote ... six in farthest socket cap
Angle screw is sheared from neck order, and therefore, when using this method, screw thread is engaged tighter bearing locking ring and at the scene can not
Realize dismounting.
Second method：When dismantling at the scene, retaining ring is fastened on bearing locking with four hexagon socket cap head screws
On ring, the mating special spanner 30 of hook spanner or producer is then fixed on bearing locking ring（See Figure 12）, pulled by hammering
Handle end installs the method for extension bar additional to achieve the purpose that dismantle bearing locking ring on spanner handle.Using striking wrench pommel
Method can equally cause hexagonal cylindrical head joint bolt in four to be frequently broken because of interrupted exciting force；And use extension bar
Method when, not only gene basis barrier spanner can not be made to rotate（Because the circumference spacing of retaining ring groove and adjacent grooves is insufficient
10mm need to choose a conjunction according to the handle of retaining ring groove angle of operation and hook spanner from basic limit rotation angle
The angle of suitable retaining ring groove adjustment hook spanner, but because revolvable angle is smaller, torsional forces is too when extension bar is shorter
It is small, and when extension bar is longer, extension bar itself when stripping ring being caused not rotate, adds because dismounting resistance bends compared with conference
Power bar, which has touched Equipment Foundations, can not continue to dismantle）, can not finally dismantle.Therefore, it is impossible to circle rotation and according to retaining
Ring groove angle frequently switches the case where spanner, not only influences disassembly efficiency problem（Since speed reducer output shaft is away from Equipment Foundations
Height only 260mm, in the case where not installing extension bar, with hook spanner dismount bearing locking ring when, hook spanner
Speed reducer cannot be surrounded to input（Go out）Axis circles）, and it is unable to reach the purpose of dismounting bearing locking ring.
The third method：FALK monoblock type speed reducer complete machines are returned into factory's maintenance, both the above method is taken when returning factory's maintenance
When cannot solve the problems, such as, the method for vehicle pin bearing stripping ring is taken to be dismantled, repairs reduction box dismounting when returning dress on lathe
After circumfili button, new stripping ring is installed.
Due to some are objective, axial direction when being operated such as speed reducer when the thermal expansion force of axis generation, helical gear operating
Impact of the factors such as active force to bearing locking ring, screw thread damage is general more serious at bearing locking ring " screw thread dislocation ", the
A kind of and second of method for dismounting at the scene cannot substantially complete the dismounting of bearing locking ring and take it is more, and the third
Method is not only a kind of a kind of method to damage equipment part as cost, and cost is larger and time-consuming longer.It is appreciated that
