Accompanying drawing explanation
For ease of illustrating, the utility model is described in detail by following preferred embodiment and accompanying drawing.
Fig. 1 is a kind of clutch friction steel disc of the utility model prosthetic device profile;
Fig. 2 is a kind of clutch friction steel disc of the utility model prosthetic device schematic diagram.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Please refer to Fig. 1-2, a kind of clutch friction steel disc prosthetic device of the present utility model, comprising: comprising: consistency from top to bottom, the upper reconditioning plate 1 leaving gap and lower reconditioning plate 3, and on this, the bottom of reconditioning plate 1 and the top of lower reconditioning plate 3 are provided with reconditioning plate 2; On this, reconditioning plate 1 is provided with the gap location of lower reconditioning plate 3: be positioned at the central gear 4 in centre position, steel disc fixture 5, the perimembranous of this steel disc fixture 5 is fixedly installed the external tooth 11 engaged with central gear 4, this steel disc fixture 5 offers the retaining hole 6 of installing friction steel disc, reconditioning plate 1 offers for this through hole 8 for adding lapping liquid, nozzle 9 can add lapping liquid by this through hole 8.On this, the peripheral part of reconditioning plate 1 and lower reconditioning plate 3 is provided with the internal gear 7 engaging, provide for steel disc fixture 5 rotary power with the external tooth 11 on steel disc fixture 5.
Wherein, on this, reconditioning plate 1 and lower reconditioning plate 3 are all connected with power set, and these power set make reconditioning plate 1 and lower reconditioning plate 3 do to rotate in the other direction.The quantity of this steel disc fixture 5 is multiple, is evenly distributed on the periphery of central gear 4.Preferred as one, the quantity of this steel disc fixture 5 is 3.This steel disc fixture 5 is provided with multiple grinding fluid apertures 10.
This retaining hole 6 is used for the friction steel disc of retaining clip between upper and lower reconditioning plate when grinding.Upper reconditioning plate 1, lower reconditioning plate 3 are made rightabout and are rotated, the planetary motion of revolution and rotation done by friction steel disc in retaining hole 6, adopt planetary gears, central gear 4 drives steel disc fixture 5, makes friction steel disc loopy moving between the outer ring and inner ring of reconditioning plate 2.Adopt Independent adjustable speed motor to drive, after being slowed down by reductor, carry out speed governing separately to upper reconditioning plate 1, lower reconditioning plate 3, central gear 4 by the gear of different speed ratio, obtain different turning and spend, make it reach optimal rotating ratio.When reconditioning friction steel disc, location is kept by the retaining hole 6 on steel disc fixture 5, friction steel disc is placed in this retaining hole 6, then be clipped between the upper reconditioning plate 1 posting reconditioning plate 2, lower reconditioning plate 3, nozzle 9 supplies lapping liquid to abradant surface by through hole 8 on one side, and reconditioning plate rotates the two-sided of the friction of reconditioning simultaneously steel disc up and down.
The method of this clutch friction steel disc prosthetic device is used to be:
First utilize friction steel disc Special-purpose peening machine to carry out shot peening strengthening to friction steel disc, then use clutch friction steel disc prosthetic device to carry out reconditioning to friction steel disc, two kinds of modes are organically combined, complete and friction steel disc is manufactured again.Shot peening strengthening improves one of fatigue of materials, the most effective method in life-span, by carrying out shot-peening to friction steel disc surface, it is made to produce micro-plastic deformation, surface produces work hardening, increases friction steel disc case hardness, improves wearability, make the micro-plastic deformation on friction steel disc surface, eliminate its inner residual stress existed, avoid the germinating of fatigue crack, increase the service life.
The reconditioning plate of the different trade mark can be adopted to carry out reconditioning friction steel disc, the reconditioning plate trade mark is between 80# ~ 360#, the selection of the concrete reconditioning plate trade mark is then determine according to the repairing standard of friction steel disc, the general reparation rule to friction steel disc first adopts the preliminary grinding of coarse sand reconditioning plate, then repair with the fine grinding of fine sand reconditioning plate, to reach speed change box clutch with the trade mark of the steel disc corresponding reconditioning plate that rubs to rub the different instructions for uses that steel disc manufactures again by changing.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
