Abstract
A vehicle starting motor with a reinforced commutator comprises a tubular commutating segment and a commutator substrate; wherein the commutator substrate is connected with the inner wall of the commutating segment, the head of the commutating segment extends forwards and outside a concave front ferrule, the tail of the commutating segment extends backwards and outside a concave back ferrule, thefront ferrule and the back ferrule are uniformly sheathed by reinforcing rings, the head and the tail of the commutator substrate are both flanged outwards, thereby fixing the reinforcing rings between the commutator substrate and the commutating segment. The utility model only lengthens two ends of the commutating segment of prior commutator by 2mm to 3mm, and adds two reinforcing rings on the circumference formed by the commutating segment, to significantly improve the strength of the commutator. The vehicle staring motor has simple manufacture without improving the manufacture cost of commutator.
Description
(1) technical field
The utility model relates to a kind of automobile start motor.
(2) background technology
The volume of starter is all developing to miniaturization, and its mentality of designing all is to improve rotating speed of motor basically, strengthens step-down ratio, thereby to commutator requirement of strength more and more higher (36000r/min overspeed test 1min, adjacent commutator segment changes≤0.005).The commutator segment of starter commutator and connecting of commutator matrix of present usefulness, generally be extruding wedge-shaped slot or punching out dovetail groove in commutator segment, get in wedge-shaped slot or the punching out dovetail groove when commutation matrix plastic and the die casting of glass fibre silk ribbon, and form commutator integral body.But because commutator is comparatively elongated, plastic substrate and glass tape have inhomogeneous when clamp-oning commutator wedge-shaped slot or punching out dovetail groove, or the pore generation, thereby have reduced the bond strength of parallel operation sheet and commutator matrix.
(3) summary of the invention
In order to overcome the above-mentioned deficiency of automobile start motor in the prior art, the utility model provides a kind of automobile start motor with commutator of reinforcing.
The technical scheme in the invention for solving the technical problem is: a kind of automobile start motor with commutator of reinforcing, the commutator segment and the commutator matrix that comprise tubular, described commutator matrix is connected with the inwall of described commutator segment, the head of described commutator segment extends the front ferrule of indent forward, the afterbody of described commutator segment extends back the back lasso of indent, described front ferrule and back evenly are arranged with fixing collar on the lasso, thereby the head of described commutator matrix and afterbody all turn up described fixing collar is fixed between described commutator matrix and the commutator segment.
Further, described fixing collar is a glass fiber.
The beneficial effects of the utility model are: only need to install former commutator commutator segment two ends lengthening 2～3mm additional two fixing collars on its formed circumference, just can significantly improve commutator intensity.Technology realizes simple, does not increase the manufacturing cost of commutator.
(4) description of drawings
Fig. 1 is a structural representation of the present utility model.
(5) embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
With reference to Fig. 1, a kind of automobile start motor with commutator of reinforcing, the commutator segment 1 and the commutator matrix 2 that comprise tubular, described commutator matrix 2 is connected with the inwall of described commutator segment 1, the head of described commutator segment 1 extends the front ferrule of indent forward, the afterbody of described commutator segment 1 extends back the back lasso of indent, described front ferrule and back evenly are arranged with fixing collar 3 on the lasso, thereby the head of described commutator matrix 2 and afterbody all turn up described fixing collar 3 is fixed between described commutator matrix 2 and the commutator segment 1.In the present embodiment, described fixing collar 3 is the high strength glass silk fiber.
The utility model only needs to install former commutator commutator segment two ends lengthening 2～3mm additional two fixing collars on its formed circumference, just can significantly improve commutator intensity.Technology realizes simple, does not increase the manufacturing cost of commutator.
Claims (2)
1. automobile start motor with commutator of reinforcing, the commutator segment and the commutator matrix that comprise tubular, described commutator matrix is connected with the inwall of described commutator segment, it is characterized in that: the head of described commutator segment extends the front ferrule of indent forward, the afterbody of described commutator segment extends back the back lasso of indent, described front ferrule and back evenly are arranged with fixing collar on the lasso, thereby the head of described commutator matrix and afterbody all turn up described fixing collar is fixed between described commutator matrix and the commutator segment.
