Abstract

The utility model discloses a motor-used double insulation rotor shaft case. The rotor shaft case comprises a rotating shaft (1) and a rotor iron core sheet (2). Rotor end plates (3) and a plastic shaft case (4) are injection moulded together by one time. The rotating shaft (1) is coated with the plastic shaft case (4) by injection moulding. The rotor iron core sheet (2) is interposed between and clamped by the two rotor end plates (3). By adopting the motor-used double insulation rotor shaft case, the production efficiency can be increased as an operation step is omitted by the improvement, and the quantity of mold inserts put in the mould is reduced, thereby shortening the operation time, increasing the production efficiency, saving time, electric power and manpower, and improving the qualified rate of the products.

Description

The two insulation rotor bag axles of motor

Technical field:

The utility model relates to technical field of motors, more specifically to the two insulation rotor bag axles of a kind of motor.

Background technology:

As shown in Figure 1, existing motor is comprised of rotating shaft A1, rotor lamination A2, rotor insulation end plate A3 and plastic packets axle A4 with two insulation rotor bag axles, during production, at first produce rotor end plates A3, then two rotor insulation end plate A3, rotor lamination A2, rotating shaft A1 are put into to plastic film with the mold insert form and inject plastic packets axle A4, so just formed two insulation rotor bag axles.Its weak point is: 1, it is to process by the secondary operation, two road injection mouldings have been passed through, namely first inject rotor insulation end plate A3, then put together and inject plastic packets axle A4, the rotor insulation end plate A3 processed like this is squeezed yielding and damages in mould, products waste, reduce the qualification rate of finished product greatly.2, adopt two road orders to increase production cost, reduced production efficiency.

The utility model content:

The purpose of this utility model is exactly the deficiency for prior art, and provide motor two insulation rotor bag axles, it has improved production efficiency, after improvement, can save a procedure, and reduced the quantity of putting mold insert in mould, and shortened the operating time, improved production efficiency, the power saving less manpower that saves time simultaneously, conforming product rate is high.

Technology solution of the present utility model is as follows:

Motor, with two insulation rotor bag axles, comprises rotating shaft and rotor lamination, and rotor end plates is in the same place with plastic packets axle once injection moulding, and the rotating shaft injection moulding is coated in the plastic packets axle, and rotor lamination is clamped between two rotor end plates.

In described rotating shaft, form several V-shape grooves, the injection moulding entity of plastic packets axle stretches into and tamps in this V-shape groove.

The beneficial effects of the utility model are:

1, it has improved production efficiency, can save a procedure after improvement, and has reduced the quantity of putting mold insert in mould, has shortened the operating time, has improved production efficiency.

2, owing to having economized the injection moulding operation one, the power saving less manpower so it saves time.

3, no longer need first injection mo(u)lding rotor end plates, thus do not exist rotor end plates by crushing, to be produced the problem of substandard products, so improved conforming product rate.

The accompanying drawing explanation:

Fig. 1 is the structural representation of prior art;

Fig. 2 is structural representation of the present utility model.

In Fig. 2: 1, rotating shaft; 11, V-shape groove; 2, rotor lamination; 3, rotor end plates; 4, plastic packets axle.

Embodiment:

Embodiment: as shown in Figure 2, motor, with two insulation rotor bag axles, comprises rotating shaft 1 and rotor lamination 2, and rotor end plates 3 is in the same place with plastic packets axle 4 once injection mouldings, rotating shaft 1 injection moulding is coated in plastic packets axle 4, and rotor lamination 2 is clamped between two rotor end plates 3.

In described rotating shaft 1, form several V-shape grooves 11, the injection moulding entity of plastic packets axle 4 stretches into and tamps in this V-shape groove 11.

Operation principle: rotating shaft 1 and rotor lamination 2 are put into to mould, then disposable rotor end plates 3 and the plastic packets axle 4 of injecting, rotor end plates 3 is in the same place with plastic packets axle 4 once injection mouldings like this, no longer need first injection mo(u)lding rotor end plates, so do not exist rotor end plates by crushing, to be produced the problem of substandard products, so improved conforming product rate.

Claims
