Abstract
The utility model discloses a formula of inserting side reinforcement ring, its characterized in that: including central ring body and inserted block, the inserted block sets up along the outer circumferencial direction of central ring body, leave between the adjacent inserted block and let the fixed foot of commutator copper sheet along the male circumference space of radial direction, then leave between the excircle of central ring body and the inserted block and carry out the radial space that the center cramped to the fixed foot of commutator copper sheet, the excircle of central ring body is radially to be equipped with a plurality of extension boards, the extension board is the same and the one-to-one with the quantity of inserted block, the rear end of inserted block is connected with the overhang end of extension board, the inserted block, extension board and central ring body are integrative injection moulding structure. The utility model discloses can carry out the center to the commutator copper sheet from the side direction and cramp, improve the structural strength and the hypervelocity performance of commutator.
Description
Technical Field
The utility model relates to a commutator, concretely relates to reinforcing ring of commutator.
Background
The commutator is widely applied to working occasions such as electric tools, automobile motors and the like, and in order to improve the structural strength and the overspeed performance of the commutator, some commutators with high rotating speed requirements usually adopt a reinforcing ring to reinforce a copper sheet of the commutator. However, when the fastening feet on the commutator sheet are provided with only strip-shaped windows with closed peripheries, the reinforcing ring of the prior art is ineffective, and the commutator sheet cannot be tightened, particularly the commutator sheet cannot be tightened in the center.
Disclosure of Invention
In view of the not enough of background art, the utility model aims at providing a can follow the side direction and carry out the center to the commutator copper sheet and cramp, improve commutator structural strength and overspeed performance's side formula of inserting and consolidate the ring.
The utility model adopts the following technical proposal to complete:
side formula of inserting reinforcement ring, its characterized in that: including central ring body and inserted block, the inserted block sets up along the outer circumferencial direction of central ring body, leave between the adjacent inserted block and let the fixed foot of commutator copper sheet along the male circumference space of radial direction, then leave between the excircle of central ring body and the inserted block and carry out the radial space that the center cramped to the fixed foot of commutator copper sheet, the excircle of central ring body is radially to be equipped with a plurality of extension boards, the extension board is the same and the one-to-one with the quantity of inserted block, the rear end of inserted block is connected with the overhang end of extension board, the inserted block, extension board and central ring body are integrative injection moulding structure.
Above-mentioned technical scheme's side formula of inserting reinforcing ring, the inserted block that its was equipped with makes the reinforcing ring can insert the bar fenestration that the fixed foot of commutator copper sheet was equipped with from the side direction in, and the periphery of bar fenestration is confined, and when the inserted block inserted the bar fenestration of fixed foot, because leave between the excircle of central ring body and the inserted block and carry out the radial space that the center cramped to the fixed foot of commutator copper sheet, so the excircle of central ring body can be supported with the medial surface of fixed foot and lean on, so, the reinforcing ring just can carry out the center cramping to the commutator copper sheet from the side direction, improve commutator structural strength and hypervelocity performance.
Preferably, the insert block, the extension plate and the central ring body are made of glass fiber reinforced phenolic resin materials.
Drawings
The utility model discloses there is following figure:
figure 1 is a schematic structural diagram of the present invention,
fig. 2 is a top directional diagram of fig. 1.
Detailed Description
As shown in the figure, the utility model discloses a formula reinforcing ring is inserted to side adopts glass fiber reinforcement phenolic resin material, including central ring body 1 and inserted block 3, inserted block 3 sets up along the outer circumferencial direction of central ring body 1, leaves between the adjacent inserted block 3 and lets the fixed foot of commutator copper sheet along radial direction male circumference space 4, then leaves between the excircle of central ring body 1 and the inserted block 3 and carry out the radial space 5 that the center cramps to the fixed foot of commutator copper sheet, the excircle of central ring body 1 is radially to be equipped with a plurality of extension boards 2, extension board 2 is the same and one-to-one with the quantity of inserted block 3, the rear end of inserted block 3 links to each other with the overhang end of extension board 2, inserted block 3, extension board 2 and central ring body 1 injection moulding structure as an organic whole.
Claims (2)
1. Side formula of inserting reinforcement ring, its characterized in that: including central ring body and inserted block, the inserted block sets up along the outer circumferencial direction of central ring body, leave between the adjacent inserted block and let the fixed foot of commutator copper sheet along the male circumference space of radial direction, then leave between the excircle of central ring body and the inserted block and carry out the radial space that the center cramped to the fixed foot of commutator copper sheet, the excircle of central ring body is radially to be equipped with a plurality of extension boards, the extension board is the same and the one-to-one with the quantity of inserted block, the rear end of inserted block is connected with the overhang end of extension board, the inserted block, extension board and central ring body are integrative injection moulding structure.
2. The laterally inserted reinforcement ring of claim 1, wherein: the insert block, the extension plate and the central ring body are made of glass fiber reinforced phenolic resin materials.
