Abstract
The utility model discloses a kind of tank commutators, including matrix and set on the groove profile commutator segment of matrix outer circle, insulation between plates is carried out by mica sheet between adjacent groove profile commutator segment, it is characterized by: the outer circle of groove profile commutator segment has an equal amount of outer diameter, the outer circle of groove profile commutator segment opens up bonding wire slot at top；The dovetail foot and described matrix secure bond, the dovetail foot that groove profile commutator segment is equipped with by its medial surface are equipped with dovetail groove；The reinforcing rib position that the dovetail foot is connected with groove profile commutator segment is equipped with sawtooth three-legged structure on left and right side.The utility model has the advantages that saving, and the cost of material is low, structural strength is high.
Description
Technical field
The utility model relates to commutator technical fields, and in particular to a kind of tank commutator.
Background technique
The commutator of the prior art, including hook, groove profile and three kinds of face type.Tank commutator has groove profile commutator segment,
Groove profile commutator segment will be equipped with riser station at the top of groove profile commutator segment because bonding wire slot is arranged, i.e. groove profile commutator segment
Top outside diameter is greater than the outside diameter at other positions in various degree, and consumptive material can be more, improves production cost.In addition,
Groove profile commutator segment will be by fixed feet and commutator base secure bond that its medial surface is equipped with, and fixed feet generally uses simple
Dovetail configuration or oat tail groove structure, it is not strong enough with the binding force of matrix, therefore tank commutator stability after molding is poor, i.e.,
The integral strength of tank commutator is not high, is unfavorable for the raising of its mechanical strength and the performance that exceeds the speed limit.
Summary of the invention
In view of the deficiency of background technique, having saving the purpose of the utility model is to provide one kind, the cost of material is low, knot
The tank commutator of the high advantage of structure intensity.
The utility model adopts the following technical scheme that complete:
Tank commutator, by cloud including matrix and between the groove profile commutator segment of matrix outer circle, adjacent groove profile commutator segment
Master slice carries out insulation between plates, it is characterised in that: the outer circle of groove profile commutator segment has an an equal amount of outer diameter, groove profile commutator segment it is outer
Circle opens up bonding wire slot at top.
The dovetail foot and described matrix secure bond, the dovetail foot that groove profile commutator segment is equipped with by its medial surface are equipped with
Dovetail groove.
The reinforcing rib position that the dovetail foot is connected with groove profile commutator segment is equipped with sawtooth three-legged structure on left and right side.
The tank commutator of above-mentioned technical proposal, uses right circular cylinder structure, and groove profile commutator segment is not required to opening up bonding wire
Riser station is arranged in the position of slot, therefore while feeding intake saves the raw material of riser station redundance, reduces production cost, improves former
The utilization rate of material；Secondly, fixed feet sets the dual dovetail configuration of dovetail groove using dovetail footmuff, increase tank commutator molding
Stability afterwards；In addition, being equipped with sawtooth triangle on the left and right side at the reinforcing rib position that dovetail foot is connected with groove profile commutator segment
Structure increases the lateral bonded area between groove profile commutator segment and the bakelite powder material of matrix, thus increase groove profile commutator segment with
Lateral binding force between matrix, improves the integral strength of tank commutator.
Preferably, the sawtooth three-legged structure is symmetrical arranged on the left and right side at reinforcing rib position.
Detailed description of the invention
The utility model has following attached drawing:
Fig. 1 is the structural schematic diagram of the utility model,
Fig. 2 is the structure chart of groove profile commutator segment in Fig. 1,
Fig. 3 is the right view of Fig. 2.
Specific embodiment
As shown, the tank commutator of the utility model, including matrix 2 and set on the groove profile commutator segment of 2 outer circle of matrix
1, insulation between plates is carried out by mica sheet 8 between adjacent groove profile commutator segment 1, the outer circle of groove profile commutator segment 1 has an equal amount of outer
Diameter, makes tank commutator become right circular cylinder structure, and the outer circle of groove profile commutator segment 1 opens up bonding wire slot 3 in top position.The slot
The three dovetail feet 4 and described matrix secure bond, every dovetail foot 4 that type commutator segment 1 is equipped with by its medial surface are equipped with one
A dovetail groove 5, so that making the fixed feet of groove profile commutator segment 1 has dual dovetail configuration.The dovetail foot 4 and groove profile commutator segment 1
Connected reinforcing rib position 6 is equipped with sawtooth three-legged structure 7 on left and right side, and the sawtooth three-legged structure 7 is at reinforcing rib position 6
Left and right side on be symmetrical arranged.
