Abstract
The utility model discloses Novel commutator, the commutation copper sheet that the excircle being included in commutator body is evenly laid, commutation copper sheet is provided with sheet pin and implants in commutator body and commutator body strong bonded, sheet pin is made up of the riser of the narrower floor of width and wider width, it is characterized in that: commutation copper sheet divides commutation copper sheet A and commutation copper sheet B two type, commutation copper sheet A and commutation copper sheet B is laid staggeredly at the excircle of described commutator body, its floor of sheet pin of commutation copper sheet A is less at commutator length dimension in the radial direction, its floor of sheet pin of commutation copper sheet B is larger at commutator length dimension in the radial direction, its riser of sheet pin of commutation copper sheet A and commutation copper sheet B staggers non-interference in commutator position in the radial direction mutually.The utility model specially less for radial dimension, commutation copper sheet sheet number is more and have the commutator product of high-speed demand and design, and can strengthen the bond strength between commutation copper sheet and commutator body, improves the mechanical performance of commutator product.
Description
[technical field]
The utility model relates to a kind of improvement invention of commutator product.
[background technology]
Commutator is used widely in motor, electric tool product, the essential structure of commutator is: the commutation copper sheet that the excircle being included in commutator body is evenly laid, described commutation copper sheet is together with commutator body injection-compression molding, and described commutation copper sheet is provided with sheet pin and implants in commutator body and commutator body strong bonded.For strengthening the bond strength between commutation copper sheet and commutator body, improve the mechanical performance of commutator product, the maximum method of current employing be improve sheet pin structure and reinforcing ring is set, improving the optimal technical scheme of sheet leg structure is then the size adding large stretch of pin.But it is less for radial dimension, the commutator product that commutation copper sheet sheet number is more, the gauge (referring in commutator size circumferentially) of its sheet pin (sheet pin is made up of the riser of the narrower floor of width and wider width) size particularly its riser portion of sheet pin is subject to strict restriction, spacing between its riser of sheet pin of each adjacent commutation copper sheet can be very little, if add the gauge of its riser of wide sheet pin, so contact with very easily colliding during commutator body together pressure injection at commutation copper sheet between its riser of adjacent sheet pin, thus cause the commutator product percent defective after injection-compression molding to remain high.
[summary of the invention]
For the deficiencies in the prior art, the purpose of this utility model be to provide a kind of special less for radial dimension, commutation copper sheet sheet number is more and have the product of high-speed demand and design, the bond strength between commutation copper sheet and commutator body can be strengthened, improve the Novel commutator of product mechanical performance.
For solving the problems of the technologies described above, the utility model takes following technical scheme:
Novel commutator, the commutation copper sheet that the excircle being included in commutator body is evenly laid, described commutation copper sheet is together with commutator body injection-compression molding, described commutation copper sheet is provided with sheet pin and implants in commutator body and commutator body strong bonded, the cross section of described pin is T-shaped, described pin is made up of the riser of the narrower floor of width and wider width, described riser is connected with commutation copper sheet body by floor, it is characterized in that: described commutation copper sheet divides commutation copper sheet A and commutation copper sheet B two type, commutation copper sheet A and commutation copper sheet B is laid staggeredly at the excircle of described commutator body, its floor of sheet pin of commutation copper sheet A is less at commutator length dimension in the radial direction, its floor of sheet pin of commutation copper sheet B is larger at commutator length dimension in the radial direction, its riser of sheet pin of commutation copper sheet A and commutation copper sheet B staggers non-interference in commutator position in the radial direction mutually.
Adopt the commutator of technique scheme, due to adjacent commutation copper sheet its floor of sheet pin different at commutator length dimension in the radial direction, its riser of sheet pin of adjacent commutation copper sheet is staggered mutually in commutator position in the radial direction, so riser both sides just can reserve larger space to widen the gauge of riser and can not mutually interfere, so not only strengthen the bond strength between commutation copper sheet and commutator body, improve the mechanical performance of commutator product, and avoid and contact with colliding during commutator body together pressure injection at commutation copper sheet, ensure that the quality of commutator product.Therefore, the utility model can be suitable for that radial dimension is less, commutation copper sheet sheet number is more very well and have the commutator product of high-speed demand.
As preferably, the centre of described floor offers elongated hole.

The utility model has following accompanying drawing:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is the structure chart of commutation copper sheet B;
Fig. 4 is the left view of Fig. 3;
Fig. 5 is the structure chart of commutation copper sheet A;
Fig. 6 is the left view of Fig. 5.
[embodiment]
Each details and the operation principle thereof of the utility model embodiment is further described below in conjunction with accompanying drawing.
As shown in the figure, Novel commutator of the present utility model, the commutation copper sheet that the excircle being included in commutator body 1 is evenly laid, described commutation copper sheet is together with commutator body 1 injection-compression molding, described commutation copper sheet is provided with sheet pin and implants in commutator body 1 and commutator body 1 strong bonded, the cross section of described pin is T-shaped, described pin is made up of the riser 3 of the narrower floor 2 of width and wider width, described riser 3 is connected with commutation copper sheet body by floor 2, described commutation copper sheet divides commutation copper sheet A and commutation copper sheet B two type, commutation copper sheet A and commutation copper sheet B is laid staggeredly at the excircle of described commutator body 1, its floor 2 of the sheet pin of commutation copper sheet A is less at commutator length dimension L2 in the radial direction, its floor 2 of the sheet pin of commutation copper sheet B is larger at commutator length dimension L1 in the radial direction, its riser 3 of the sheet pin of commutation copper sheet A and commutation copper sheet B staggers non-interference in commutator position in the radial direction mutually, the gauge b of riser 3 has wider width than tradition, the centre of described floor 2 offers elongated hole 4.
Above-mentioned commutator product, due to adjacent commutation copper sheet its floor of sheet pin different at commutator length dimension in the radial direction, its riser of sheet pin of adjacent commutation copper sheet is staggered mutually in commutator position in the radial direction, so riser both sides just can reserve larger space to widen the gauge of riser, so not only strengthen the bond strength between commutation copper sheet and commutator body, improve the mechanical performance of commutator product, and avoid and contact with colliding during commutator body together pressure injection at commutation copper sheet, ensure that the quality of commutator product.Therefore, the utility model can be suitable for that radial dimension is less, commutation copper sheet sheet number is more very well and have the commutator product of high-speed demand.
