Abstract
The utility model discloses a tin-copper commutator, which is characterized by comprising commutator bars, wherein the commutator bars are fixed by pressed bakelite powder, mica sheets are arranged between the commutator bars, the commutator bars are also fixed by a strengthening ring, a bushing is arranged in the inner hole of the commutator, and the commutator bars are made of a tin-copper alloy material. The tin-copper commutator is low in cost, high in mechanical properties and very strong in abrasion resistance.
Description
Technical field
The utility model relates to a kind of improvement invention of commutator.
Background technology
What the commutator segment (claiming copper bar again) of tradition commutator generally adopted all is to be raw material with copper; Can reach higher mechanical property and very strong anti-wear performance though in copper, add silver; But the price of silver is higher, and only in the group of motors of having relatively high expectations, the client just requires to add silver.
Summary of the invention
In view of the deficiency of prior art, the utility model provides a kind of cost low, has the tin copper commutator of higher mechanical property and very strong anti-wear performance.
For solving the problems of the technologies described above; The utility model takes following technical scheme to accomplish: tin copper commutator is characterized in that: comprise commutator segment, commutator segment is fixed through the phenolic moulding powder of compacting; Be provided with mica sheet between the sheet of commutator segment; Commutator segment is also fixed through reinforcing ring, is provided with lining at the endoporus of commutator, and commutator segment adopts tin copper alloy material.
Through the enforcement of technique scheme, the commutator of tin copper alloy material commutator segment (tin of adding 20% in copper) reaches higher mechanical property and very strong anti-wear performance equally, but cost has obviously reduced.
Description of drawings
The utility model has following accompanying drawing:
Fig. 1 is the structural representation of the utility model,
Fig. 2 is the left view of Fig. 1.
Embodiment
Come the utility model is done detailed explanation through a specific embodiment below:
As illustrated in fig. 1 and 2, the tin copper commutator of the utility model comprises commutator segment 1; Commutator segment 1 is fixing through the phenolic moulding powder 2 of compacting; Be provided with mica sheet 5 between the sheet of commutator segment 1, commutator segment 1 is also fixed through reinforcing ring 4, is provided with lining 3 at the endoporus of commutator; Described commutator segment 1 adopts tin copper alloy material, and this tin copper alloy material is to realize through the tin of adding 20% in copper.The tin copper commutator of the utility model, important technological parameters: 1. strength test: 500V/1S between sheet, bobbin 2500V/30S does not take place to puncture or flashover; 2. hot overspeed test: 180 ℃/50000rpm/3min, the external diameter variation is not more than 0.012mm, and the section difference is not more than 0.002mm between sheet.The tin copper commutator of above-mentioned technical parameter, the same with the commutator that in copper, adds silver, can reach higher mechanical property and very strong anti-wear performance equally.
