Four, instance analysis
1, the measurement of Double cone up rolling correlation parameter and reckoning
If take No. 1 awl as example, cone diameter m
1=80.32mm, bipyramid height n
1=183.30mm, a
1=353.3mm, bearing end play dynamic height h
0=152.7mm;
,
,
, the theoretical calculate value that the bearing end cone is rolled
High by No. 1 cone, establish the double cone body and be rolled to track end (gear cone thing just is installed in rail supported bar top) when locating, it is high that the length A B=360.88mm that cone is rolled, its spacing are cone, the gear cone thing distance of hanging down to the axis
, in △ ABE1,
, then,
, as shown in Figure 7,
Can extrapolate the corresponding angle (scale) that track end support bar leg rotates along circular arc by formula (5)
Can just be so that selected double cone roller track bearing end should falling head
, 152.7 bearing ends play dynamic height
2. regulating step and method
Leveling base, by axis of an orbit socket end support bar and track end support bar elevating screws, make two-orbit at grade, at this moment, axis of an orbit socket end lower support bar pin occupy the chute high order end, recording the relative base plate height of two-orbit upper surface is 190.4mm, according to selected No. 1 awl as above the parameter of calculating regulate as follows:
(1) is under the same plane state at as above two guide rails, reads axis of an orbit socket end and the corresponding scale of track end support bar
,
, then bicone rail spacing at the moving whole story is
, namely the axis of an orbit socket end is to gear cone thing spacing.As shown in Figure 7;
(2) by as above calculating, left and right sides track end support bar goes to corresponding scale along circular arc separately and should be
, at this moment, gear cone thing spacing should equal double cone height 183.30mm.As shown in Figure 7;
(3) fixed screw of loosening track bearing lower support bar elevating screws, rotation oscilaltion spiral reduces axis of an orbit socket end support bar height, and feet is moved successively cycling in proportion along the second main scale direction, make it, the bearing end falling head 190.4～
(152.70mm) and near the critical altitude theoretical value, the actual axle socket end drops to 152.70mm from 194.40mm, the 37.70mm that descended, DB section as shown in Figure 6;
(4) allow track end and the rotating shaft of support bar junction with orbital direction is consistent separately, lock all link fixed screws;
(5) No. 1 awl is placed on the two-orbit initiating terminal and looses one's grip, cone just begins to roll, and examines cone motion conditions on its track.Hence one can see that, and just the roll experiment value of critical altitude of double cone body is 37.70mm, with theoretical value relatively 39.66mm relatively,, the error of its generation only only has 4.94%.
Experiment has just verified that Double cone up rolling experiment condition (1) is correct thus.
Be worth explanation: too fast if bicone does not roll or rolls, should again carry out regulating shaft socket end falling head by above-mentioned steps
Value is tested repeatedly, until the double cone body just rolls, verifies with this whether the Double cone up rolling condition is correct.
Five, error and analysis
This No. 1 cone of selecting is tested, and its percentage error only has 4.94%.Subsequently, we have selected again 2,3, No. 4 bicones to test, shown in table (1).
The correlation parameter of three bicone relative dimensions of table 1. when calculating that gear cone thing is just above the track end support bar
Be reduced to respectively critical altitude
Near all fail to starts, and the actual starting of each cone elemental height is
, descend respectively 29.5mm, 23.8mm, 22.0mm of bearing end track just is the critical altitude of cone starting, with each Double cone up rolling theoretical calculate critical value
Compare, the theoretical calculate value is all greater than experiment value, and shown in table (1), its percentage error is respectively 6.79%, 5.56%, 5.58%.Although there is certain error in the new equipment experiment, has traced it to its cause two, elastic deformation because race way diameter is thinner, has occured in one; Its two, cone starting stiction is larger.
