As shown in Fig. 1-2 and Figure 27, main bearing journal beat project detection in, being respectively arranged at two ends with of bent axle 17
One support apparatus 19, make measurement trunnion beat project time operator can rotate smoothly bent axle by one hand.
Use this support apparatus 19 carry out trunnion beat the detection of project time, comprise the steps:
1) two bearing assemblies 19 are placed on measuring table, first with adjustment bolt 16, slide plate 3 are turned down, make axle connect roller
14 away from left V-block 1 and right V-block 5.Then bent axle 17 is lifted on two bearing assemblies 19 so that bent axle 17 two ends
Trunnion is clamped between inclined-plane 110 and the inclined-plane 51 of right V-block 5 of left V-block 1, but trunnion does not connect roller 14 and connects with axle
Touch.
2) slowly the slide plate 3 of two bearing assemblies 19 is heightened with adjustment bolt 16, make axle connect roller 14 and bent axle 17
Trunnion contacts, and now trunnion does not contacts with left V-block 1 and right V-block 5.Then slowly two are adjusted with adjustment bolt 16
The slide plate 3 of bearing assembly 19, the axis making bent axle is parallel with the datum level of platform.
Now, turning crankshaft 17 gently so that axle connects roller 14 and rotates with bent axle, reduce the frictional force rotated, the most available
Dial gauge 19 carries out the detection of project of beating.
3) after being measured, first with adjust bolt 16 slide plate 3 of two bearing assemblies is turned down, make axle connect roller 14 away from
The trunnion of bent axle 17, now trunnion is clamped between inclined-plane 110 and the inclined-plane 51 of right V-block 5 of left V-block 1.Then will
Bent axle 17 hangs bearing assembly 19.
During measuring, if operator forgot to connect axle roller 14 before being lifted on bearing assembly by bent axle
Turn down, then bent axle 17 can bump against axle and connects roller 14, and two lining rollers 8 that now axle connects below roller 14 connect roller 14 1 with axle
Rise and undertake impact force and the gravity of bent axle, it is to avoid it is subjected to large compressive and damage that axle connects roller.
In this utility model, axle connect roller use cantilevered install, its be positioned at trunnion an end rather than in
Portion, it is to avoid when rotating bent axle, axle connects the surface of roller and contacts with the oilhole in the middle part of trunnion and produce additional jitter, it is ensured that
The accuracy measured and reliability；Lining roller connects the aiding support of roller as axle, loses because of operation when alleviating lifting bent axle
By mistake the most countershaft even roller collides brought loss of significance, extends the life-span of bearing assembly；Slide plate sets with adjustment bolt
Put so that the operation switching lifted, measure and hang between bent axle can easily realize so that measure safer, laborsaving；This
Bearing assembly is applicable not only to the platform measuring of Large Crankshaft, is equally applicable to the project survey of beating of other overweight revolving parts.
The aforementioned description to specific illustrative embodiment of the present utility model illustrates that and the purpose of illustration.These
Describe and be not wishing to be defined to this utility model disclosed precise forms, and it will be apparent that according to above-mentioned teaching, can carry out
A lot of changes and change.The purpose selected exemplary embodiment and describe is to explain certain principles of the present utility model
And reality application, so that those skilled in the art is capable of and utilizes various different example of the present utility model
Property embodiment and various different selection and change.Scope of the present utility model is intended to by claims and equivalent thereof
Form is limited.
