Abstract
The utility model discloses a dustproof ring for a brush motor commutator. The dustproof ring is installed on the end part of the commutator and a rotary sealing is provided between the dustproof ring and a shell. The outer circumference of the dustproof ring is evenly provided with a plurality of protruding blades. According to the dustproof ring provided by the utility model, the plurality of protruding blades are evenly arranged on the outer circumference of the dustproof ring, so that the dustproof ring rotates together with a rotor, and carbon dust deposited in a commutating groove can be blown off by the wind produced by the dustproof ring blades, thereby being capable of effectively solving a problem that the carbon dust deposits in the groove of the commutator. In addition, the dustproof ring is simple in structure and is low in cost.
Description
Technical field
The utility model relates to brush motor, relates in particular to brush motor commutator dust ring.
Background technology
Produce carbon dust in the brush motor course of work, carbon dust produces a lot of problems after in the switching-over tank, piling up.Be head it off in the prior art, mainly take the measure of two aspects:
1. stifled source: adopt the carbon brush of other materials, such as the carbon brush of argentiferous, but cost can uprise.
2. open stream: increase the gumming device.Can increase fan, change wind path, even additional air pump blow away carbon dust.
But said method not only cost is high, and complex structure.
The utility model content
The utility model technical problem to be solved just provides a kind of brush motor commutator dust ring, can effectively solve the problem that carbon dust is piled up in the switching-over tank, and simple in structure, with low cost.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: brush motor commutator dust ring; Dust ring be installed on the commutator end and with the shell rotary seal, it is characterized in that: said dust ring ring excircle evenly is provided with some outstanding blades.
As preferably, said blade is located at the adjacent commutator end of dust ring and blade tip bends towards the commutator direction.
As preferably, between said dust ring and shell labyrinth seal structure.
The utility model evenly is provided with several outstanding blades at dust ring ring excircle; When rotor rotates like this; Dust ring rotates together, and the wind-force that the dust ring blade produces can blow the accumulation carbon dust in the switching-over groove off, can effectively solve the problem that carbon dust is piled up in the switching-over tank; And it is simple in structure, with low cost.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described:
Fig. 1 is the structural representation of the utility model after being applied on the commutator.
Embodiment
Specify the utility model brush motor commutator dust ring embodiment in conjunction with Fig. 1; Commutator 2 is located at rotor 1 end and is rotated with rotor; Dust ring 3 be installed on commutator 2 ends and with shell 4 rotary seals, said dust ring ring excircle evenly is provided with some outstanding blades 5.Said blade is located at the adjacent commutator end of dust ring and blade tip bends towards the commutator direction.It between said dust ring and shell labyrinth seal structure.
The fan blade type dust ring rotates with rotor, has strengthened the commutator flow velocity of air-flow on every side, can improve petard (possibility of carbon dust and dust accretions in the switching-over tank), further reduces carbon brush and commutator temperature, improves bulk life time.
Claims (3)
1. brush motor commutator dust ring, dust ring (3) be installed on commutator (2) end and with shell (4) rotary seal, it is characterized in that: said dust ring ring excircle evenly is provided with some outstanding blades (5).
2. brush motor commutator dust ring according to claim 1 is characterized in that: said blade is located at the adjacent commutator end of dust ring and blade tip bends towards the commutator direction.
3. brush motor commutator dust ring according to claim 1 is characterized in that: be labyrinth seal structure between said dust ring and shell.
