Abstract
The utility model relates to a novel reinforced commutator which comprises a bakelite main body and commutator pieces arranged at the periphery of the bakelite main body. Each commutator piece comprises a working segment positioned on the outer surface of the bakelite main body and a fixing leg extending into the bakelite main body, and a groove extending into the bakelite main body is arranged between the working segment and the fixing leg of each commutator piece. An insulation reinforcing rod is disposed in each groove. The insulation reinforcing rods can directly act on the commutator pieces and exhibit excellent reinforcing performance. Moreover, compared with conventional reinforcing rings, the insulation reinforcing rods exhibit better rigidness since there is a wide area of contact between each insulation reinforcing rod and each fixing leg.
Description
Technical field
The utility model relates to a kind of reinforcing commutator, relates in particular to the good novel reinforced commutator of a kind of reinforcement performance.
Background technology
Existing reinforcing commutator, be the intensity that is improved commutator by assembly reinforcing ring in the hook groove in commutator segment, described reinforcing ring mainly contains two kinds, and a kind of is ferrule, but the employing ferrule causes easily to puncture between sheet and sheet and opens circuit, and causes proof voltage bad.And also need to fill phenolic moulding powder between commutator segment and ferrule, thereby make the bulk strength of commutator relatively poor, easy deformation has influenced the mechanical performance of commutator, is difficult to satisfy the requirement of pot motor.Another kind of is no latitude glass fiber reinforcement ring, though this class reinforcing ring can directly contact with commutator segment, its thermal endurance is relatively poor, and when motor ran up, this class did not have latitude glass fiber reinforcement ring and is easy to explosion, thereby influenced the operate as normal of commutator.
The utility model content
The purpose of this utility model is to overcome the defective that prior art exists, and provides a kind of reinforcement performance good novel reinforced commutator.
The technical scheme that realizes the utility model purpose is: a kind of novel reinforced commutator, comprise bakelite main body and the commutator segment that is arranged in bakelite main body periphery, described commutator segment comprises the active section that is positioned at bakelite main body outer surface and the fixing feet that stretches into the bakelite main body, be provided with the groove that stretches in the bakelite main body between the active section of described commutator segment and the fixing feet, be provided with insulation in the described groove and reinforce rod.
Preferably, described insulation reinforcing rod is ceramic rod.
Preferably, the cross section of described insulation reinforcing rod is circular or oval.
The utlity model has positive effect: insulation is reinforced rod and can be acted directly on the commutator segment, has good reinforcement performance, and compared to existing reinforcing ring, it is big with the contact area of fixing feet that rod is reinforced in insulation, has better rigidity.
Description of drawings
Content of the present utility model is easier to be expressly understood in order to make, according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail below, wherein:
Fig. 1 is structural representation of the present utility model.
Wherein: 1, bakelite main body, 2, commutator segment, 21, active section, 22, fixing feet, 3, insulation reinforces rod.
Embodiment
Embodiment 1
As shown in Figure 1, a kind of novel reinforced commutator, the commutator segment 2 that comprises bakelite main body 1 and be arranged in bakelite main body 1 periphery, commutator segment 2 comprises the active section 21 that is positioned at bakelite main body 1 outer surface and the fixing feet 22 that stretches into bakelite main body 1, be provided with the groove that stretches in the bakelite main body 1 between the active section 21 of commutator segment 2 and the fixing feet 22, be provided with insulation in the groove and reinforce rod 3.
In above-described embodiment 1, insulation is reinforced rod 3 and can be acted directly on the commutator segment 2, has good reinforcement performance, and compared to existing reinforcing ring, it is big with the contact area of fixing feet 22 that rod 3 is reinforced in insulation, has better rigidity.
Embodiment 2
As preferred embodiment, all the other are identical with embodiment 1, and difference is that it is ceramic rod that rod 3 is reinforced in insulation, and the cross section that rod 3 is reinforced in insulation is circular.
In above-described embodiment 2, the ceramic rod heat resistance is stable, has good explosion-proof performance, prevents that the puncture between the commutator segment 2 from opening circuit.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection range of the present utility model.
Claims (3)
