The experimental implementation explanation of chute-type three-dimensional regulation quantitative verification Double cone up rolling condition experiment instrument of the present utility model：
1st, Double cone up rolling experiment instrument is assembled；
2nd, three adjustable support lower limbs 1 below adjusting base 2, make leveling spirit bubble 3 in circle central authorities；
3rd, left track 10 turns to initial position with 11 top chute rotating wheel 10-2 of right track, by 10 terminal of left track
Left support legs and feet 8 are placed on initial position, i.e. left track 10 with right track 11 in flat with the right support legs and feet 9 of 11 terminal of right track
Row state, now, reads the main scale corresponding with 11 top of right track position in chute of left track 10 and vernier cursor scale value α1,
As shown in Fig. 8, Fig. 2, Fig. 3；
4th, the upper and lower adjustable screw 8-3 of left support lower limb and the upper and lower adjustable screw of right support lower limb of right track 11 to left track 10
9-3 carries out coarse adjustment, makes left track 10 approximate horizontal with right track 11, and then horizon rule is placed in left track 10 and right track 11
Surface different azimuth, the upper and lower adjustable screw 8-3 of the fine tuning left support lower limb and upper and lower adjustable screw 9-3 of right support lower limb, is allowed to horizon rule
Upper spirit bubble is in circle central authorities, as shown in Fig. 2, Fig. 3 and Fig. 8；
5th, according to final the rolled position of the given double cone body basal diameter of teacher, height, and cone, calculate relevant parameter；
6th, according to the relevant parameter for being calculated, by 11 end support legs and feet 9 of 10 end support legs and feet 8 of left track and right track
Respective distance is moved symmetrically along left support legs and feet chute 8-9 and right support legs and feet chute 9-8 respectively, this process, left track 10 are last
End rotates axle 10-0 and 11 end of right track rotates axle 11-0 and can rotate axle cunning in 10 end of left track respectively
Road 10-8 rotates mobile respective distance in axle slideway 11-8 with 11 end of right track, is allowed to 10 end support legs and feet of left track
8 and 11 end support legs and feet of right track, 9 spacing be close to s, simultaneously, left track 10 horizontally rotates this process around a left track top left side
Axle A1(10-00) rotate, right track 11 surrounds right track top horizontal rotating shaft A2(11-00) rotate；Again horizon rule is placed
In left track 10 and 11 upper surface different azimuth of right track, respectively the upper and lower adjustable screw 8-3 of adjustable track end left support lower limb with
The upper and lower adjustable screw 9-3 of right support lower limb, is allowed to the blister of horizon rule in circle centre position, again ensures that left track 10 with the right side
Track 11 is in same level.As shown in Fig. 8, Fig. 2, Fig. 3；
The 7th, left and right track (10,11) top chute rotating wheel 10-2 is swung down to the angle of reckoning along chute 12,
Locking left and right track top chute rotating wheel bearing lock screw, specific bicone is put in orbit, along 12 side of chute
To slowly mobile chute rotating wheel 10-2 up and down, it is allowed to till bicone just slowly rolled along left and right track (10,11) direction,
Read now left and right track (10,11) top position correspondence main scale and vernier cursor scale α2, then left and right track (10,11) plane institute
Gyration is Δ α=α2-α1, as shown in Figure 4.
8th, calculate respectivelyWith tan Δ α, see whether meet Double cone up rolling condition：
Checking Double cone up rolling condition experiment principle：
1st, the projectional technique of left and right track top rotational angle
In left and right track by this with regard to centrage under the horizontal precondition of symmetrical, parallel and upper surface.If known bicone
Basal diameter m and height n, double cone body apex angle ssi, determine that left and right track end supports legs and feet symmetrically to move with regard to base centerline
Dynamic distance s, the then interorbital angle γ in left and righti, left and right track top rotates axle rotational angle around left and right track end
(i.e. left and right orbit plane with respect to the horizontal plane inclination angle) αi, as shown in Figure 9 and Figure 10.Then
tanβi=m/2/n/2=m/n ... (1)
According to bicone height n, left and right track angle half tangent is determined
tanγi/ 2=s/2/l=s/2l ... (2)
According to Double cone up rolling condition
Allow
tanβi/2·tanγi/ 2=fi ……(4)
Then tan αi<fi, obtain
αi<acr tan fi ……(5)
2nd, Double cone up rolling tests the measuring method of relevant parameter
Three supporting legs of adjusting base, allow base spirit bubble in circle central authorities, merge cone experiment instrument or so track end
End supports legs and feet, is allowed to left and right parallel track, rotates left and right track top chute rotating wheel and is horizontal, locks left and right rail
Horizon rule is placed on the different azimuth on the track upper surface of left and right, is adjusted respectively by road top chute rotating wheel bearing lock screw
The upper and lower adjustable screw of section left and right track end support bar, (horizon rule bubble is located at circle in same level to be allowed to two tracks
Central authorities) on, read the initial present position major-minor chi reading α in left and right track top1, according to selected basal diameter mi, high niCone
Body, symmetrical mobile left and right track end support legs and feet, and it is s (s to be allowed to left and right track end and support legs and feet center distance<ni), then
The tangent of left and right track angle half
tanγi/ 2=s/2/l=s/2l ... (6)
Calculate the tangent of bicone drift angle half
tanβi/ 2=m/n ... (7)
Allow
tanβi/2·tanγi/ 2=fi ……(8)
There are tan αi<fi, then
α0<acr tan fi ……(9)
The angle that then track top in left and right should be turned over is about in α0<acrtanfiNear, and α is adjusted in its vicinityi
When, bicone is just rolled, then the angle that left and right track is turned over is：
Δ α=αi-α0<αi-acr tan fi……(10)
It should be strongly noted that being rolled on the track of left and right for a long time to demonstrate bicone, need advancing the track long
Gear cone thing (A) can be fixed on track least significant end by degree, then left and right track end gear cone thing (A) spacing should be not more than bicone
Height ni, now, cone thing place track end position can will be kept off using similar triangles and be scaled to left and right track end vertically side
Locate above axle to rotating, be so assured that left and right track end supports the spacing between legs and feet center, so that it is determined that
Left and right track end supports legs and feet with respect to centrage moving interval s.
Instance analysis：
1st, the measurement of Double cone up rolling relevant parameter charges to table 1 with reckoning result；
2nd, experimental procedure and method (summary)；
3rd, error and analysis such as table 1.
1.4 bicone relative dimensions of table and relevant parameter during gear cone thing place track end position
