Abstract
The present invention relates to an insulating ring used for the electric power electromechanics industry, particularly to a design method of an insulating ring to improve quantity and reliability. An insulating ring is made from the composite material of fiber cloth and insulating paper, wherein the fiber cloth can be glass fiber cloth and can also be nonwoven fabric glass cloth; the insulating paper can be mica paper and can also be asbestos paper. The design method of an insulating ring can improve the electric appliance performance and the mechanical performance of the insulating ring, and consequently, overcomes the disadvantages that products have instable quantity and low reliability.
Description
Affiliated technical field: the invention belongs to the dead ring of using in the power motor industry, particularly can change electrical structure, the electrical equipment size is dwindled, the better dead ring of performance about a kind of.
Prior art: the dead ring that present power motor industry is used is the micarex of mica sheet with sticker system, forming through suitable technology compacting, or using glass fiber material, forms through suitable technology compacting.These two kinds of methods all belong to homogenous material and stick with glue and connect compacting and form, produce to press make all occur easily in the process scribing, cracking, in uneven thickness, the production qualification rate is lower; And in a single day slide plate, cracking, in uneven thickness etc. appear in dead ring, influence the insulation property and the mechanical performance of electrical equipment.When producing use, bigger hidden danger is arranged, cause down the road unstable product quality.The patent No. 99106639.1 discloses a kind of dead ring that adopts fiber cloth and insulating paper composite material to make, but can not change electrical structure, and the electrical equipment size is dwindled.
The objective of the invention is: a kind of dead ring is provided, and it can improve electrical equipment, the mechanical performance of dead ring, changes electrical structure, and the electrical equipment size is dwindled.
Technical scheme of the present invention is: a kind of dead ring is provided, it is characterized in that: dead ring adopts fiber cloth and insulating paper composite material to make; There is the V-type groove dead ring upper surface, dead ring outer circle Surface Vertical degree α
1Be 1 °～7 °, the joint face on V-type groove and circle surface, outer is a cambered surface.
Described dead ring outer circle Surface Vertical degree α
1It is 2 °～6 °.
The perpendicularity α of the joint face on described V-type groove and circle surface, outer
2It is 20 °～30 °.
The perpendicularity α of the joint face on described V-type groove and circle surface, outer
2It is 20 °～25 °.
Described dead ring is to form with fiber cloth, insulating paper, mica sheet compacting.
Described fiber cloth is glass fabric or non-woven glass cloth.
Described insulating paper is mica paper or asbestos paper, can also be aromatic polyamide paper.
Characteristics of the present invention are: because the α of DC motor commutator dead ring
1, α
2When angle diminishes, can change electrical structure, the electrical equipment size is dwindled, performance is better.It has adopted multi-layer fiber cloth, multilayer insulation paper, multilayer glue space, has superposeed, is compositely suppressed to form, it utilizes multiple material property complementation, so improved the uniformity and the mechanical performance of dead ring thickness, prevent slide plate, cracking, improved electrical insulation properties, also further improved the quality of dead ring, this kind method is used for the design of DC motor commutator dead ring, use the back product quality to improve greatly, it is more than 90% that product percent of pass rises to by original 60%.
The present invention will be further described below in conjunction with the embodiment accompanying drawing.
Accompanying drawing: be embodiment DC motor commutator dead ring cross-sectional view.
Among the figure: 1, dead ring; 2, V-type groove.
Embodiment is as shown in the figure: dead ring 1 adopts 8 stratus master slices, the female paper of 9 stratus, 9 layers of fiber cloth, multilayer glue space, superposes, is compositely suppressed to form.Dead ring 1 upper end is connected with V-type groove 2, dead ring 1 outer circle Surface Vertical degree a
1 Be 5 °, the perpendicularity a of V-type groove and outer circle face joint face
2Be 23 °, two inclined-plane line stretcher intersection diameter of phi are 331mm, and height H is 90mm, and thickness δ is 2.5mm.
Claims (7)
