Gear distress analogue means based on fault toothed disc of the present utility model, can realize the switching of fault gear and the switching of fault toothed disc assembly, and concrete grammar is as follows:
1, the switching of fault gear
Gear distress analogue means based on fault toothed disc of the present utility model changes meshing gear by rotation fault toothed disc input module, thereby reaches the object that fault gear switches.Gathered after a kind of signal of gear distress, need to be switched to next fault gear to be measured, its method of operating is as follows:
First, before switching fault gear to be measured, should remove the constraint between all fault toothed disc input modules and casing, concrete operations are: take off the belt that high speed shaft 4 end belt pulleys 8 are connected with motor, take off the second bolt 15 and the register pin 16 on case lid 18, so just whole releasing of the constraint between fault toothed disc and casing on the first bolt 14, the second bearing (ball) cover 13 on clutch shaft bearing end cap 9.
Then, adjust the position of fault toothed disc input module, after former meshed gears drop out of gear, the fault gear 5 to be measured of needs engagement is adjusted to the position of engaging with low speed gear 10.Before rotating fault toothed disc input module, should make former fault gear to be measured 5 and low speed gear 10 drop out of gears, concrete operations are: manually move axially fault toothed disc input module to the position of low speed gear 10 drop out of gears.Move axially distance and be approximately 1.2 times of low speed gear facewidth, practical operation can fault toothed disc input module moves to rotate and is as the criterion.Gear drop out of gear afterwards clockwise or counterclockwise (being determined by demand) rotates to an angle fault toothed disc input module, angular dimension is determined by fault number of gears, then, manually fault toothed disc input module being shifted onto to origin-location (clutch shaft bearing end cap 9 has axial location effect) and being regulated makes it engage with low speed gear 10, if occur can not transverse shifting situation low speed gear is rotated to a minute angle, just realized like this switching of fault gear.
Finally, fault toothed disc input module is fixed on casing.Concrete operations are: rotation register pin 16 makes the second bearing seat 7 tight with back up pad 17 laminatings in casing 1, again the second bolt 15 on the first bolt 14 on clutch shaft bearing end cap 9 and the second bearing (ball) cover 13 is screwed, install belt it is connected with loading motor.So just, realized the switching to fault gear to be measured.
2, the switching of fault toothed disc input module
The fault toothed disc that gear distress analogue means based on fault toothed disc of the present utility model contains different faults type by custom pack reaches the object of the multiple gear distress of Fast simulation, simulate more fault and only need change fault toothed disc input module and corresponding parts, concrete operations are as follows:
First, before switch failure toothed disc input module, should remove the constraint between all fault toothed disc input modules and casing.Concrete operations are: take off the belt on high speed shaft 4 end belt pulleys 8 and electrical machine belt pulley, take off the first bolt 14 on clutch shaft bearing end cap 9, register pin 16 on the second bolt 15 and case lid 18 on the second bearing (ball) cover 13, the part that is connected and fixed between fault toothed disc input module and casing has all been removed like this.In addition while, also needing several belt pulleys 8 of high speed shaft end and the second bearing (ball) cover 13 to take off to ensure mobile fault toothed disc input module, end cap and fault toothed disc input module do not interfere.
Then, take off whole fault toothed disc input module, change new fault toothed disc input module.Concrete operations are: move axially fault toothed disc input module until separate with casing 1 along high speed shaft 4, new fault toothed disc input module is installed into box house, and (installation method and the method for taking off fault toothed disc input module are in like manner, reversed in order), the position of manually adjusting fault toothed disc input module makes one of them the fault gear 5 to be measured on fault toothed disc input module engage with low speed gear 10.
Finally, fault toothed disc input module is fixed on casing.Concrete operations are: the second bearing (ball) cover 13 is installed, then several belt pulleys 8 are arranged on to several high speed shaft 4 ends successively.Next rotate register pin 16 the second bearing seat 7 and the back up pad 17 in casing 1 are fitted, then the second bolt 15 on the first bolt 14 on clutch shaft bearing end cap 9 and the second bearing (ball) cover 13 is screwed, install belt it is connected with loading motor.So just, realized the switching to fault toothed disc input module.
