Rotation of the main shaft drives the load shafts to rotate; as the gears adopt the design provided by the utility model, when the main shaft rotates 0 DEG to 90 DEG, the first load shaft is driven to rotate, and when the main shaft rotates 90 DEG to 180 DEG, the second load shaft is driven to rotate. When the transmission mechanism disclosed by the utility model implements a dual-switching state on the transfer switch, the main shaft can be locked, the isolation function required by an isolation switch can be realized; and the mechanism has the advantages of simple structure, flexible operation and high reliability.
Description
Technical field
The utility model relates to a kind of electric switch equipment, relates in particular to a kind of transmission mechanism of automatic change-over.
Background technology
In order to realize maintenance and the reliability service of power distribution circuit, conventionally automatic change-over need to be installed in power distribution circuit, the decapacitation that requires to this automatic change-over provides outside the duplicate supply of load end, and load end isolation features and the fire-fighting in particular job in zero-bit also should have circuit are cut non-functional.
In order to meet above-mentioned requirement, designer is usually designed to the structure of change over switch the stack of two isolating switches or is merged pattern, thereby can between be connected to and guarantee reliably the isolation performance of automatic change-over in circuit, in addition, utilize this structure to operate the feature of two isolating switches can be different time, the time that also can realize the load end zero setting position of conversion change over switch is controlled and insulation request that can padlock, the automatic change-over of this pattern is easy to realize in operating aspect, but, in realization, divide → zero → close, close → zero → minute transfer process time, should set up the transmission mechanism of an external impetus to change over switch operation, and, the output form of this transmission mechanism power should be the rotation mode of axle, 0～180 ° of the angular range of the output of axle.
To the transmission mechanism of this pattern, all adopt multipole connecting rod to amplify traction transmission method in the market and realize, this structure is because multipole connecting rod amplifies and the deviation that produces during processing and manufacturing can cause great error accumulation to the transmission of this structure.Cause transmission mechanism not steady and discontinuous sense when operation automatic change-over, and the operating characteristics that reduces product, as limited or overcome the generation of this phenomenon, must improve machining accuracy, still, can cause like this difficulty of processing large, reduce qualification rate.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of transmission mechanism of PC level three position automatic change-overs, this transmission mechanism should be able to be realized the rotary course of (0 °～90 °～180 °) or (180 °～90 °～0 °) in operating process, and should be able to can control arbitrarily according to need of work the stop over time in three angle points.
In order to achieve the above object, target of the present utility model is to provide a kind of transmission mechanism that rotates transfer mode, and this transmission mechanism answers in transmission process that link is few, steady, continuity is good and simple in structure, easily processing and manufacturing.In order to achieve the above object, target of the present utility model is to provide a kind of transmission mechanism that rotates transfer mode, the rotation angle range of this mechanism should be 0 °～180 °, and should be divided into two stages, clockwise 0 °～90 ° and 90 °～180 ° or counterclockwise 180 °～90 ° and 90 °～0 °.Two stages should be independent separately in to the transmittance process of two load axis, is independent of each other mutually.
The transmission mechanism of the automatic change-over by hereinafter, above-mentioned object target and other objects are all more obvious by what become, this transmission mechanism comprises: gear, circle wheel, main shaft, wherein circle wheel comprises disk and straight pin, gear is arranged on main shaft, circle wheel is arranged on the load axis of automatic change-over, main shaft is arranged on the housing of automatic change-over, be placed in the centre of two load axis of automatic change-over, and the position of these three axles also point-blank, the position of gear on square shaft is sustained height with circle wheel in the position of load axis, so, gear and the straight pin phase interlock of justifying in wheel, when rotating, main shaft can drive load axis to rotate simultaneously, realized the basic transmission agency of the utility model, main shaft can drive first load axis rotation in above-mentioned transmission process in the time of 0 °～90 °, in the time of 90 °～180 °, can drive second load axis rotation, in addition, gear adopts the be separated by semi-circular design of gears of 45 ° of three teeth, circle wheel adopts four straight pins on concyclic position and the design of the 45° angle degree of being separated by.

Embodiment
With reference to accompanying drawing 1, from the structural perspective of the transmission mechanism of automatic change-over, can see, main shaft 2 is arranged on the housing of automatic change-over, be positioned at the centre of two load axis of automatic change-over, and three axles are arranged in a straight line, in addition, can also see that on two load axis, a circle being respectively housed takes turns, gear on main shaft 2 can be taken turns phase interlock with two circles on load axis, rotary main shaft 2 can drag load axis rotation, this transmission mechanism amplifies without multipole connecting rod, do not produce deviation cumulative, therefore, transmission mechanism stable and continuous in transmission process is good, simple in structure.
With reference to accompanying drawing 2, accompanying drawing 3, drive mechanism at the utility model automatic change-over comprises a main shaft 2, gear is arranged on main shaft 2, gear is the angle at 45 °, three teeth and between cog interval, thereby can realize main shaft and when rotating 0 °～90 °, can drag first load axis rotation, in half-twist～180, ° can drag second load axis and rotate, two stages are independent separately, are independent of each other.
With reference to accompanying drawing 4, the transmission mechanism of the utility model automatic change-over comprises two circle wheels, be arranged on respectively on two load axis of automatic change-over, its height is identical with the gear of installing on main shaft 2, to realize and both mutual interlocks, and the object that reaches this mechanism driving revolving force, circle wheel comprises two disks 4 and four straight pins 3, four straight pins 3 are arranged on the centre of two disks 4, and the be separated by angle of 45 ° of a concyclic Zhou Shanghe who is positioned at disk 4, to realize disk 4 and the interlock of gear phase, during rotation, two of automatic change-over load axis two stages within the scope of 0 °～90 ° and 90 °～180 ° are independent separately, be independent of each other.Thereby can reach automatic change-over, when two minutes positions, can there is the isolation features of isolating switch, and can padlock protection and operator to automatic change-over the control of the time in zero-bit object.
