Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
See Fig. 1 to Fig. 5, a kind of shaft coupling axial displacement degree detecting device, comprising: telescopic slide jacking block assembly 1, rotatable square shaft assembly 7, extension spring 10, housing, clock gauge 8, clock gauge mosaic set 9, push rod block 5;
Between described two telescopic slide jacking block assemblies 1, a rotatable square shaft assembly 7 is housed, telescopic slide jacking block assembly 1 top is equipped with 12, two extension springs 10 of two extension spring fixed legs and is contained on four extension spring fixed legs 12 and is coupled together by two telescopic slide jacking block assemblies 1.
In telescopic slide jacking block assembly 1 and rotatable square shaft assembly 7 bottom surface and two sides, housing 2,13 is housed, bottom surface housing 2 pars intermedia has long ellipse open slot 21, open slot 21 is while be equipped with clock gauge mosaic set 9 for ellipse, clock gauge mosaic set 9 is fixed on one piece of telescopic slide jacking block assembly 1 through bolt 14 and cushion block 15, and in clock gauge mosaic set 9, close-fitting has clock gauge 8.Open slot 21 another side is extended with push rod block 5, and push rod block 5 is fixed on another block telescopic slide jacking block assembly 1, and clock gauge detects push rod 6 and withstands push rod block 5; Described push rod block 5 is L shape, and L shape has adjustment tank 3, and push rod block 5 is fixed on telescopic slide jacking block assembly 1 through adjustment tank 3 by bolt 4, and L shape another side is detected push rod 6 by clock gauge and withstands, and can be adjusted the position of push rod block 5 by adjustment tank 3.Housing except comprising bottom surface housing 2 and two sides housing 13, also comprise top to in-flanges 11, telescopic slide jacking block assembly 1 can wrap by housing, and limits telescopic slide jacking block assembly 1 and can only move to two ends.
See Fig. 8, described telescopic slide jacking block assembly 1 comprises jacking block 101, screw rod shifting disc 18, coaxial counterscrew 20, internal thread 19 hole is had in two pieces of jacking blocks 101, coaxial counterscrew 20 both ends are contained in internal thread hole and are coupled together by two pieces of jacking blocks 101, in the middle part of coaxial counterscrew 20, screw rod shifting disc 18 are fixedly housed.Telescopic slide jacking block assembly 1 is two limit telescopic slide ejecting blocks, because the thread rotary orientation on coaxial counterscrew 20 2 limit is contrary, so when adjusting bolt shifting disc 18 to two bearing circle and moving, will promote or receive two pieces of jacking blocks 101 and release or indentation to two limits; What in figure, X showed is that the dish adjusting bolt shifting disc 18 moves direction.
See Fig. 6 and Fig. 7, described rotatable square shaft assembly 7 comprises rotatable square shaft 16 and square rib axis body axle core 17, and square rib axis body axle core 17 embeds in rotatable square shaft 16, rotatable square shaft 16 outer corners cavetto, and square rib axis body axle core 17 two ends are right cylinder.Rotatable square shaft 16 and square rib axis body axle core 17 can be two parts, also can be integrations, the rotatable square shaft body of integration and square rib axis body axle core processing more complicated.
Square rib axis body axle core 17 on described rotatable square shaft assembly 7 can be pulled by spanner and drive telescopic slide jacking block assembly 1 to move, and clock gauge 8 can measure telescopic slide jacking block assembly 1 amount of movement.See Fig. 9, spanner can be a standard wrench 31, also can be a special spanner, and described special spanner is made up of two standard wrench, 31, two connecting shafts 32, in the middle of two standard wrench, two connecting shafts 32 are housed to connect, wrench opening 33 can the side's of blocking rib axis body axle core 17.In use can with one independently standard wrench 31, also can use special spanner, special spanner uses steadily, stress equalization, and special spanner is longer simultaneously, and the arm of force is longer, and time firmly, telescopic slide jacking block assembly 1 thrust is larger.
Shaft coupling axial displacement degree detecting device of the present invention use procedure is as follows:
See Figure 10, shaft coupling axial displacement degree detecting device 44 of the present invention is placed in the axial neutral of shaft coupling 43 to be detected and power end 41, shaft coupling 43 and load side 42; Distance adjusts axial neutral, opens the jacking block 101 of the telescopic slide jacking block assembly 1 of shaft coupling axial displacement degree detecting device 44 of the present invention, if can be jumped the queue with cushion block not.So shaft coupling axial displacement degree detecting device 44 of the present invention also can be used for detecting the axial displacement degree of other main equipments, such as wheel box, heavy motor etc.
See Figure 11, when detecting, shaft coupling axial displacement degree detecting device 44 of the present invention is had extension spring side as active side, and active side can see whole rotatable square shaft assembly 7, can by the wrench opening side of blocking rib axis body axle core 17.In use can with one independently standard wrench, but use steadily not as good as special spanner of the present invention, stress equalization.Figure 12 shows that by special spanner to a direction firmly the jacking block 101 of telescopic slide jacking block assembly 1 is extrapolated under leverage.The arm of force of special spanner is longer simultaneously, and force and the fulcrum of lever are longer, and time firmly, telescopic slide jacking block assembly 1 thrust is larger.
During operation, shaft coupling axial displacement degree detecting device 44 of the present invention is placed in the axial neutral of shaft coupling to be detected, the screw rod driver plate 18 of adjustment telescopic slide jacking block assembly 1, two limit jacking blocks 101 can adjust, whether enough suitablely observe jacking block stroke, if not, can at telescopic slide jacking block assembly 1 fore-clamp choker block block, if enough, adjust shifting disc 18 of the present invention, jacking block 101 is made to hold out against in the axial neutral of shaft coupling to be detected, jacking block 101 rate of tension of telescopic slide jacking block assembly 1 is that shaft coupling axial displacement degree detecting device 44 of the present invention is placed in the axial neutral of shaft coupling 43 and does not loosen, the reading of adjustment clock gauge 8, the method that clock gauge 8 adjusts is, the push rod block 5 corresponding to detection push rod 6 of adjustment clock gauge, and bolt 4 is fixed, the reading of adjustment clock gauge 8 is a positive integer (as+6mm) of interference, when spanner is exerted oneself, when telescopic slide jacking block assembly 1 is outwards mobile, the reading of clock gauge 8 will " back to zero " direction, reading as clock gauge is+2mm, then play value is the difference of clock gauge reading, i.e. 6-2=4mm, play value is 4mm.More close to " zero-bit ", show that shaft coupling 43 axial displacement degree is larger, exceed regulation axial displacement degree and just need maintenance; Otherwise " back to zero " degree is very little, and show that shaft coupling 43 axial displacement degree is little, shaft coupling 43 bearing wear is little; Judge according to testing result, and make a record.
These are only preferred embodiment of the present invention, be not intended to limit the protection domain of invention, therefore, all any amendments done within the spirit and principles in the present invention, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
