Abstract
The utility model discloses a kind of Hooked reverser, form by insulating body with at the hook commutator segment that the excircle of insulating body is evenly laid, described hook commutator segment is provided with sheet pin and implants in insulating body and insulating body strong bonded, it is characterized in that: the medial surface of the sheet pin of every hook commutator segment is provided with upper and lower two hook pin, mutually staggering in the short transverse of commutator between two hook pin up and down on adjacent hook commutation blade pin, elongated hole is provided with in the middle of described pin, sheet pin two ends are provided with square groove, arrange reinforcing ring in square groove.The utility model has the advantages that Stability Analysis of Structures, mechanical strength are high, be suitable for that radial dimension is less, commutation blade number is more and there is the Hooked reverser product of high speed performance requirement.
Description
[technical field]
The utility model relates to a kind of Hooked reverser product.
[background technology]
Commutator is mainly used in electric tool, and commutator divides hook, grooved and face type three kinds, and wherein Hooked reverser is gained the name because commutator segment is provided with crotch.In prior art, high mechanical properties requirement is reached for enabling Hooked reverser, maximum methods is adopted to be that the sheet leg structure improving hook commutator segment medial surface makes it and insulating body strong bonded, the technical scheme improving sheet leg structure optimum is then the head sizes adding large stretch of pin, but add large stretch of pin head sizes and can bring following harmful effect, special less for radial dimension, the Hooked reverser that commutation blade number is more, its sheet pin size is at circumferencial direction or be all subject to strict restriction in the radial direction, one is that sheet pin periphery can reduce for the space of filling insulating matrix material, easily cause the integrally-built instability of commutator, two be adjacent sheet pin head between distance can be too small, commutator segment together with insulating body during injection-compression molding adjacent commutator segment sheet pin between easily come in contact, thus it is defective and occur waste product to cause commutator to detect.
[summary of the invention]
For the deficiencies in the prior art, the purpose of this utility model is that to be to provide a kind of Stability Analysis of Structures, mechanical strength high, is suitable for that radial dimension is less, commutation blade number is more and has the Hooked reverser of high speed performance requirement.
The utility model takes following technical scheme:
A kind of Hooked reverser, form by insulating body with at the hook commutator segment that the excircle of insulating body is evenly laid, described hook commutator segment is provided with sheet pin and implants in insulating body and insulating body strong bonded, it is characterized in that: the medial surface of the sheet pin of every hook commutator segment is provided with upper and lower two hook pin, mutually staggering in the short transverse of commutator between two hook pin up and down on adjacent hook commutation blade pin.
Be provided with elongated hole in the middle of described pin, sheet pin two ends are provided with square groove, arrange reinforcing ring in square groove.
The Hooked reverser that the utility model provides, its Advantageous Effects that can produce is: 1. the setting of upper and lower two the hook pin of a pin medial surface increases the radial direction size of sheet pin, so strengthen the bond strength between commutator segment and insulating body to a certain extent, improve product mechanical strength; 2. due to mutually staggering in the short transverse of commutator between two hook pin up and down on adjacent hook commutation blade pin, so can effectively avoid making adjacent commutator segment contacting with incidental colliding during insulating body together injection-compression molding because of the setting of hook pin, thus ensure that the quality of Hooked reverser; 3. in the middle of a pin, the setting of elongated hole can strengthen the bond strength of commutator segment and insulating body, and the setting of reinforcing ring also can strengthen the bond strength of commutator segment and insulating body.Thus, the utility model has the advantages that Stability Analysis of Structures, mechanical strength are high, can be suitable for that radial dimension is less, commutation blade number is more and there is the Hooked reverser product of high speed performance requirement.
[accompanying drawing explanation]
Fig. 1 is the structural representation of Hooked reverser of the present utility model.
[embodiment]
As shown in the figure, Hooked reverser of the present utility model, form by insulating body 6 with at the hook commutator segment 4 that the excircle of insulating body 6 is evenly laid, described hook commutator segment 4 is provided with sheet pin 2 and implants in insulating body 6 and insulating body 6 strong bonded, the medial surface of the sheet pin 2 of every hook commutator segment 4 is provided with upper and lower two hook pin 1, mutually staggering in the short transverse of commutator between two hook pin 1 up and down on adjacent hook commutator segment 4 pin, elongated hole 3 is provided with in the middle of described pin 2, described pin 2 two ends are provided with square groove, arrange reinforcing ring 5 in square groove.
Claims (2)
