Abstract
The utility discloses a commutator bush, which comprises a bush body 1 and the outer surface of the bush body 1 has longitudinal striate process 2 and horizontal groove 3. The cross section of the longitudinal striate process 2 is formed by the connection between the wavy and the inner concaved direct grooves. The utility model solves the problem that the a micro clearance is formed between the former bush outer surface and the bakelite powder when the motor commutator is thermal stability processed, and the utility model can achieve the state that a plurality of parts have no clearance when adhered with the baklite powde, thus improving the adhesiveness and getting rid of phenomenon of the bush being slightly swinging in the commutator, and the utility model totally improves the quality of the motor commutator.
Description
One, technical field
The utility model relates to the lining that a kind of engine commutator is used.
Two, background technology
The outer surface of prior motor Liner for commutator is provided with vertical straight burr projection and transverse concave groove (as shown in Figure 3), and the cross section of this vertical straight burr projection is wavy (as shown in Figure 4).Engine commutator is after heat stabilisation process, because phenolic moulding powder is different with the Thermal Contraction Coefficient of lining, and shrinkage direction is a radial contraction, and vertically the wavy of straight burr projection is formed by connecting for oblique line, cause producing minim gap between phenolic moulding powder and the sleeve outer surface, thereby cause lining in commutator, to have slight dancing.
Three, utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, can reach the gapless Liner for commutator in many places and provide a kind of with the phenolic moulding powder bonding.
The purpose of this utility model realizes by following technical solution: a kind of Liner for commutator, comprise bush body, the outer surface of bush body is provided with vertical straight burr projection and transverse concave groove, and the cross section of described vertical straight burr projection is formed by connecting for being wavy being separated by with the indent straight trough.
After adopting the utility model, when this lining combines with phenolic moulding powder through heat stabilisation process and phenolic moulding powder when carrying out radial contraction, owing to contain the indent straight trough in vertical straight burr projection of the outer surface of bush body, thereby just can not form radial clearance, i.e. the both sides of indent straight trough and phenolic moulding powder tight bond and do not have the gap in the both sides of indent straight trough.Therefore, the utility model and phenolic moulding powder bonding can reach many places is not had the gap, has improved cohesive force, has eliminated the slight dancing of lining in commutator, can improve the quality of engine commutator on the whole.
Four, description of drawings
Below in conjunction with accompanying drawing and execution mode the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model Liner for commutator.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the structural representation of known Liner for commutator.
Fig. 4 is the B-B cutaway view of Fig. 3.
Five, embodiment
With reference to Fig. 1, Fig. 2 as can be known, the utility model Liner for commutator, comprise bush body 1, the outer surface of bush body 1 is provided with vertical straight burr projection 2 and transverse concave groove 3, and the cross section of described vertical straight burr projection 2 is formed by connecting (as shown in Figure 2) for being wavy being separated by with the indent straight trough.
Figure 3 shows that known Liner for commutator, the outer surface of this lining is provided with vertical straight burr projection and transverse concave groove, and the cross section of this vertical straight burr projection is wavy (as shown in Figure 4), and vertically the wavy of straight burr projection is formed by connecting for oblique line.
Claims (1)
1, a kind of Liner for commutator, comprise bush body (1), the outer surface of bush body (1) is provided with vertical straight burr projection (2) and transverse concave groove (3), it is characterized in that: the cross section of described vertical straight burr projection (2) is formed by connecting for being wavy being separated by with the indent straight trough.
