Abstract
The utility model relates to the technical field of reversers, in particular relates to a plug-type all-plastic reverser for a starting motor. The reverser comprises a moulding compound and a plurality of reversing pieces parallelly embedded into the periphery of the moulding compound, wherein every two adjacent reversing pieces are not in contact; two clamping positions are respectively arranged on two sides of each reversing piece; and reinforcement rings are arranged in the clamping positions. In the utility model, sheet mica between every two adjacent reversing pieces is removed, grooves required by the regulation are formed between every two adjacent reversing pieces, the adjacent reversing pieces are directly integrated with the moulding compound through injection moulding, and the reinforcement rings are arranged at two ends to connect the plurality of reversing pieces into a whole, so that the firmness of the reverser is effectively enhanced and the requirement for high rotational speed can be satisfied.
Description
Technical field
The utility model relates to the commutator technical field, particularly a kind of blade inserting full-plastic actuating motor commutator.
Background technology
Along with the constantly development of automobile industry ground, automobile-used slowdown type actuating motor use amount also constantly increases, and quality improves constantly with performance, and the existing direct-drive type that is used for moves the cold extrusion full-plastic commutator that electrizer adopted and can not satisfy high rotating speed requirement.Existing commutator is made up of moulding compound, commutator segment and the mica sheet that is embedded between the commutator segment, and because of high rotating speed, mica sheet comes off easily, influences commutator, so it can't satisfy high rotating speed requirement, so be necessary effectively to improve having commutator structure now.
The utility model content
The purpose of the utility model is defective and the deficiency to prior art, provide a kind of simple in structure, be provided with rationally, intensity is higher and can satisfy the blade inserting full-plastic actuating motor commutator that high rotating speed is wanted.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
The described a kind of blade inserting full-plastic actuating motor commutator of the utility model; Comprise moulding compound and the parallel peripheral some commutator segments of moulding compound that are embedded at; Do not contact between adjacent two commutator segments, said commutator segment both sides respectively are provided with a screens, are provided with reinforcing ring in the said screens.
Be with lining in the said moulding compound.
After adopting said structure; The utility model beneficial effect is: removed mica sheet between adjacent two commutator segments of the utility model; Directly and the moulding compound integrated injection molding, and two ends are provided with reinforcing ring, and reinforcing ring is linked to be an integral body with some commutator segments; Strengthen the firmness of the utility model effectively, thereby can satisfy high-revolving requirement.
Description of drawings
Fig. 1 is the sectional structure sketch map of the utility model.
Among the figure:
1, commutator segment; 2, moulding compound; 3, reinforcing ring; 4, lining;
11, screens.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, the described a kind of blade inserting full-plastic actuating motor commutator of the utility model comprises moulding compound 2 and the parallel some commutator segments 1 that are embedded at moulding compound 2 peripheries, also is moulding compound 2 and commutator segment 1 integrated injection molding.
Do not contact between said adjacent two commutator segments 1, to reach the purpose of insulation.Be provided with thin plastic sheet with insulation between preferred adjacent two commutator segments 1 of the utility model, when moulding compound 2 and commutator segment 1 one injection moulding, between adjacent two commutator segments 1, form thin plastic sheet.Said adjacent two commutator segments 1 adopt recessed structure at terminals, have both practiced thrift copper material, reduce the centrifugal force that runs up, and have strengthened the adhesion between commutator segment again, thereby have satisfied high rotating speed requirement.
Do not have mica between said adjacent two commutator segments 1, adopt moulding compound and without the air gap of processing, to reach the purpose of insulation.Be provided with the moulding compound insulation between preferred adjacent two commutator segments 1 of the utility model, adopt the assisted plastic cover to guarantee simultaneously, between adjacent two commutator segments 1, form the groove that regulation requires.
Said commutator segment 1 both sides respectively are provided with a screens 11, are provided with reinforcing ring 3 in the said screens 11, and reinforcing ring 3 is linked to be an integral body with some commutator segments 1, reaches the effect of reinforcing, make the utility model when high speed rotating, and commutator segment 1 is not easy to come off with moulding compound 2.For making the fastness between commutator segment 1 and the moulding compound 2 higher, said commutator segment 1 bottom is provided with and screens 11 similar structures, forms with moulding compound 2 more stably to be connected.
Be with lining 4 in the said moulding compound 2, can effectively reduce rotating shaft to moulding compound 2 extruding, reach the purpose of protection moulding compound 2, in addition, lining 4 also can further strengthen the firmness of the utility model.
The above only is the preferred embodiments of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modify, includes in the utility model patent claim.
