Abstract

The utility model discloses a coil pad, comprising an annular body on which an installing hole is arranged. The annular body possesses more than one bump, there are existed four sets of bumps, each set has two bumps, and each set of bumps are distributed on the annular body uniformly; the central line extension cord of each bump is intersected with the center of the annular body, the periphery of the annular body is equipped with a radial lead protection boss, and the inner wall of the annular body is equipped with a radial coil positioning groove. The coil pad of the utility model avoids the contact of a coil and a stator frame effectively, and avoids the retarder coil magnetic leakage and the magnetic penetrative coil pad.

Description

Coil gasket

Technical field

The utility model relates to the parts on a kind of retarder, especially a kind of coil gasket between coil and rotor frame.

Background technology

Coil and the coil gasket between the rotor frame on the traditional retarder adopt spring steel and waveform splinter mostly, so just cause coil to produce leakage field and coil seismism, affect the useful life of coil.

Summary of the invention

The purpose of this utility model is to provide a kind of coil of effectively avoiding to contact with rotor frame, avoids the coil gasket of retarder coil leakage field and coil vibrations.

In order to achieve the above object, the technical solution of the utility model is: a kind of coil gasket, comprise ring body, and have installing hole on the ring body, have more than one projection on the described ring body.

The projection of described ring body has four groups, every group of two projections, and four groups of projections are distributed on the ring body, and intersect at the center line extended line of each projection and the center of ring body.

Also have radial lead protection boss on the described ring body periphery, and have the radial coil detent on the inwall of ring body.

After adopting said structure, owing to have more than one projection on the described ring body, and also this ring body can adopt rubber to make, just can directly contact with rotor frame by the fine coil of avoiding, do not allow coil produce leakage field and coil seismism, good reliability, life-span is long, and processing cost is also low.

Description of drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the A-A cutaway view among Fig. 1.

Embodiment

The embodiment that provides below in conjunction with accompanying drawing is described in further detail the utility model.

Shown in Fig. 1,2, a kind of coil gasket comprises ring body 1, has installing hole 1-1 on the ring body 1, has more than one projection 1-2 on the described ring body 1.

Shown in Fig. 1,2, for coil and rotor frame are separated, the projection 1-2 of described ring body 1 has four groups, every group of two projection 1-2, and four groups of projection 1-2 are distributed on the ring body 1, intersect at the center line extended line of each projection 1-2 and the center of ring body 1, can certainly be that eight projection 1-2 are distributed on the ring body 1.

Shown in Fig. 1,2, in order to protect lead-out wires of coil and better set winding, also have radial lead protection boss 1-3 on described ring body 1 periphery, and have radial coil detent 1-4 on the inwall of ring body 1.

Shown in Fig. 1,2, when the utility model uses, ring body 1 is contained between coil and the rotor frame gets final product, this ring body adopts rubber to make, just can contact with rotor frame by the fine coil of avoiding, do not allow coil produce leakage field and coil seismism, the good reliability life-span is long, and processing cost is also low.
