Abstract
The utility model provides a fixing device of a slip ring of a wound motor. By the aid of the fixing device, the problem that safe operation of a motor is affected by breakage, snapping of welded joints and the like due to existing welded connection of conducting bars of a rotor and a lead wire of a slip ring is solved. The fixing device of the slip ring of the wound motor comprises a lead wire welded with the slip ring, conducting bars of a rotor and fixing parts. The technical scheme includes that an insulating material layer covers the slip ring and the lead wire after the slip ring and the lead wire are welded together, the slip ring and the lead wire are integrally assembled on a slip ring sleeve, an insulating material layer covers the periphery of the slip ring sleeve, the slip ring sleeve is sleeved on a rotary shaft, and the lead wire is connected onto the conducting bars of the rotor by bolts which are used as the fixing parts. The fixing device has the advantages that the fixing device is reasonable in structural design, the diameter of the slip ring is reduced, the linear speed of an outer circle of the slip ring is decreased, temperature rise of the slip ring is prevented, accordingly, the service life of a carbon brush is effectively prolonged, and safe and stable operation of the motor is guaranteed.
Description
Technical field
The utility model relates to a kind of coiling electric motor parts, particularly a kind of coiling electric motor slip ring fixture that slip ring and rotor are linked together.
Background technology
Along with electromechanics trade develops rapidly, wound motor is used in more widely in the field, and the critical component slip ring of wound motor the various structures form occurred also along with the development of wound motor, to adapt to the demand under different working conditions.But along with application places requires more and more harsher to motor, the slip ring lead portion of tradition wound motor, adopt the rotor busbar of Type of Welding to be fixedly connected with conducting rod, and due to structural limitations, the slip ring integral diameter is excessive, in the high rotating speed running of motor, high potential safety hazard is crossed in the slip ring temperature rise that tie point fracture easily occurs, snap and cause due to too high linear velocity, thereby affects safety, the stable operation of motor.
The utility model content
The purpose of this utility model is to provide a kind of coiling electric motor slip ring fixture, avoided existing rotor busbar to be connected problem with the slip ring wire bonds, the problem includes: easy fracture, the problem that affects the motor safety operation such as snap, its reasonable in design, reduced the slip ring diameter, reduced the linear velocity of slip ring cylindrical, prevent the slip ring temperature rise, thereby effectively extended the useful life of carbon brush, guarantee safety, the stable operation of motor.
The technical scheme that the utility model adopts is: this coiling electric motor slip ring fixture comprises lead-in wire, rotor conducting rod and the fixture that is welded with slip ring, its technical essential is: coated insulation material layer after described slip ring and wire bonds, overall package is on the slip ring sleeve of periphery coated insulation material layer, the slip ring sleeve jacket casing installs in rotating shaft, utilizes bolt as fixture, lead-in wire to be connected on the rotor conducting rod.
Advantage and the good effect that the utlity model has are: due to coated insulation material layer after slip ring of the present utility model and wire bonds, overall package is on the slip ring sleeve of periphery coated insulation material layer, adopt bolt as fixture, lead-in wire to be connected on the rotor conducting rod, so its reasonable in design, can reduce pad, reduce the slip ring diameter, reduce the linear velocity of slip ring cylindrical, prevent the slip ring temperature rise, guarantee safety, the stable operation of motor; Due to the reduction of linear velocity, effectively extended the useful life of carbon brush simultaneously.Therefore, the utility model has avoided existing rotor busbar to be connected problem with the slip ring wire bonds, the problem includes: easy fracture, the problem that affects the motor safety operation such as snap.
Description of drawings
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is a kind of concrete structure schematic diagram of the present utility model.
Sequence number explanation in figure: 1 slip ring, 2 lead-in wires, 3 slip ring sleeves, 4 bolts, 5 rotor conducting rods.
Embodiment
Describe concrete structure of the present utility model in detail according to Fig. 1～3.This coiling electric motor slip ring fixture comprises lead-in wire 2, rotor conducting rod 5 and the fixture etc. that are welded with slip ring 1.Coated insulation material layer after slip ring 1 and lead-in wire 2 firm welding wherein, according to drawing adjusted size distance, overall package is on the slip ring sleeve 3 of periphery coated insulation material layer successively.According to test specification do withstand voltage test qualified after, slip ring sleeve 3 cover installs in rotating shaft, utilizes bolt 4 as fixture, will go between 2 to be connected on rotor conducting rod 5, is connected firmly, and locks with stop washer.
