Description
Существующие способы извлечени нижних вкладышей подщипников колеичатых валов в поршневых двигател х, например, в двигател х внутреннего горени , вызывают значительные затраты времени и рабочей силы и, кроме того, в большинстве случаев требуют применени подъемных механизмов,Existing methods for extracting the lower liners of the undersized shaft bearings in piston engines, for example, in internal combustion engines, cause a considerable investment of time and labor and, moreover, in most cases require the use of lifting mechanisms,
Дл устранени этих недостатков предлагаетс приспособление, в котором, лл извлечени нижнего вкладыша, служит хомут, надеваемый на щеку колена вала и снабженный упорами дл извлекаемого вкладыша, перемещаемого при повороте вала из нижнего положени в перхнее.To eliminate these drawbacks, a device is proposed in which, to remove the lower liner, there is a collar that is put on the cheek of the shaft knee and provided with stops for a removable liner that moves when the shaft rotates from the lower position to the perhne.
На чертеже фиг. 1 изображает вид приспособлени сбоку с частичным разрезом и фиг, 2- то же, вид спереди с частичным разрезом.In FIG. 1 is a side view of the device with a partial cut; and FIG. 2 is the same, a front view with a partial cut.
Приспособление состоит из хомута 3, нижн часть которого надеваетс на .нижнюю часть щеки кривошипа и соедин етс , при помощи болтов 5, с верхлей частью 7 хомута 5, расположенного ,ка верхней части щеки. ПропущенныйThe device consists of a collar 3, the lower part of which is put on the lower part of the crank cheek and is connected, by means of bolts 5, with the upper part 7 of the collar 5 located on the upper part of the cheek. Missed
через отверстие, имеющеес в верхней части / хомута 3, болт 6 прижимает нижнюю часть ход1ута к нижней части щеки.through the hole in the upper part / collar 3, the bolt 6 presses the lower part of the stroke against the lower part of the cheek.
Вход щие в отверсти нижней чпсти хомута 3 упоры 4 служат дл зажима своими концами нижней половины вкладыша . Путем поворота вала вкладыш подшипника переместитс из нижнего положени в верхнее. Цепи 8 служат дл предохранени от падени упоров 4 во врем сборки и разборки приспособлени .The stops 4 which enter into the openings of the lower part of the clamp 3, serve to clamp with their ends the lower half of the insert. By turning the shaft, the bearing shell will move from the lower position to the upper position. The chains 8 serve to prevent the stops 4 from falling during the assembly and disassembly of the fixture.
Закладку нижнего вклaдынJa обратно на место производ т посредством этого же приспособлени .The laying of the lower jaw back into place is made by means of the same device.
Предмет изобретени .The subject matter of the invention.
Приспособление дл извлечени н ::хн х вкладышей коренных подшнпннкси коленчатых валоз, отличающеес тем, что дл перемещени вкладыша из нижнего положени в верхнее путем поворота вала слумсит неподвижно надетый на щеку колена хомут 5, снабженный упорами 4 дл кромок вкладыша.A device for extracting n :: xn x liners of crankshaft main sub-shaft crankshaft, characterized in that to move the liner from the lower position to the upper position by rotating the shaft, sling the clamp 5 fixed to the liner 4 for the liner edges.
