Description
One, affiliated technical field
The utility model relates to a kind of manual star-delta starter.
Two, background technology
Star triangle (Y-△) starter divides automatically and manual two classes.Manually star-delta starter is normal adopts cam by different outer rim shapes to make several identical in structure contact assemblies order in accordance with regulations deciliter, realizes the star triangle conversion of motor stator winding.At present, manually all there is defective in star-delta starter in contact system, rotating assembly and actuating mechanism.Contact system as shown in Figure 1, in product when work,, rotary handle drives that cam control moving contact disconnects and is closed, the single-break contact arc quenching effect of use is general, clearance between open contacts is big, impact energy is big, has to be flexible coupling complex manufacturing technology.Rotating assembly is made up of rotating shaft, lining, packing ring, ratchet, pin etc., and number of spare parts is many, and complex structure also exists the problem of radially rocking between ratchet and rotating shaft, and product is easy to wear, has influenced the useful life of product.The actuating mechanism design is unreasonable, and number of spare parts is many, not only assembling difficulty, and cause small product size big.
Three, utility model content
The purpose of this utility model is to provide a kind of manual star-delta starter, and it has characteristics such as arc quenching effect is good, clearance between open contacts is little, impact energy is little, nothing is flexible coupling, overall performance is good, manufacturing process is simple, production cost is low.
For achieving the above object, the solution that the utility model is taked is: a kind of manual star-delta starter, comprise housing, handle, contact system, rotating assembly and actuating mechanism, sold inside the country dress roller, middle both sides are taken and are loaded onto the static contact panel that is fixed with fixed contact, top dress moving contact below the slide block, place spring on the moving contact, constitute described contact system.
During product work, rotary handle drives rotating assembly, roller and slide block, and control moving contact and fixed contact are connected and disjunction.Its advantage is that arc quenching effect is good, and clearance between open contacts is little, and impact energy is little, and nothing is flexible coupling, and manufacture craft is simple, has improved the product overall performance, has reduced cost of goods manufactured.
Be fixed with the integral plastics external member by injection molded in rotating shaft, the integral plastics external member is divided into ratchet portions and cam set part, constitutes described rotating assembly.
The integral plastics external member replaces existing cam set and ratchet, and is simple in structure, and do not have radially and rotate, and wear-resistant, mechanical endurance is long, and cost is low.
On the support stationary housing, two pull bar lower end breach and two grooves of support are near as fulcrum, middlely embed two rollers, and the extension spring tension is gripped integral plastics external member ratchet portions with two rollers, constitutes described actuating mechanism.
This actuating mechanism part is few, easy to assembly, makes the starter reduced volume simultaneously.The rotating shaft assembly, it can move rapidly.
