1. the actuator of two cam disc controls has the phase place requirement each other, is divided into two cam disc processing and installation, can cause than mistake.
2. the installing space that takies is bigger.
3. be divided into two parts, process and install loaded down with trivial details.
Summary of the invention
The utility model is exactly in order to overcome the above-mentioned shortcoming of prior art, and propose a kind of simple in structure, take up room little and multiple mounted cam mechanism in the simple on load tap changer be installed.
The technical scheme that the utility model is taked is: the multiple mounted cam mechanism in the on load tap changer comprises switch motion control cam and vacuum bubbles control cam; Described switch motion control cam comprises flying wheel and is installed in the radial cams of flying wheel top; Described vacuum bubbles control cam constitutes by the plane cam of two different-diameters is compound, and the bottom circumference of the plane cam of described two different-diameters respectively is provided with a track, and each track is provided with at least one boss; Be characterized in that the flying wheel of described switch motion control cam is installed in the top of vacuum bubbles control cam, switch motion control cam and vacuum bubbles control cam are connected as a single entity, form multiple mounted cam; The center of described multiple mounted cam is provided with axis hole, is used to set firmly final drive shaft.
Multiple mounted cam mechanism in the above-mentioned on load tap changer wherein, respectively is interval with three boss of dividing equally by circumference on the base track of the plane cam of two different-diameters of described vacuum bubbles control cam.
Multiple mounted cam mechanism in the above-mentioned on load tap changer, wherein, the distance between described adjacent two boss is with the stroke decision of vacuum bubbles operate time of being controlled.
Multiple mounted cam mechanism in the above-mentioned on load tap changer, wherein, described multiple mounted cam adopts a cast molding of accurate cast steel.
Multiple mounted cam mechanism in the above-mentioned on load tap changer, wherein, the boss that is provided with on the track of two different-diameters on the described vacuum bubbles control cam staggers each other.
Because the utility model has adopted above technical scheme, therefore produced positive technique effect:
1, the whole accurate cast molding of part, the mutual alignment relation of the cam surface of each control phase of cam obtains fine assurance.
2, the installation one-time positioning is accurate, does not need the adjustment of two cam mutual alignments.
3, save installing space, make the shunting switch internal structure clean and tidy more compact.
