CN203607955U - Novel composition end hoop - Google Patents

Abstract

The utility model discloses a novel composition end hoop; in the prior art, a conventional 2P motor stator needs to mount a wind shield and a machine seat needs to design a cooling space, so under a same machine seat length, a motor capacity is designed to be small and the capacity cannot be improved; the novel composition end hoop can solve the said problems. The novel composition end hoop comprises an annular hoop body; a plurality of through holes are uniformly arranged on the hoop body in an axial direction; a plurality of slots are uniformly arranged on an outmost ring face of the hoop body in a rotary trapezoid; the outmost ring of the hoop body is a right-angle side ring face of the trapezoid body. The slots and the hoop body are parallel in central axis, and a ring, in which the through hole is positioned, is coaxial with the central axis of the hoop body; when the motor ventilation cooling condition is ensured, the technology can improve air path design of the stator, fully utilizes the machine seat space, and improves the design capacity of the 2P motor.

Description

A kind of end hoop of new structure

Technical field

This utility model relates to a kind of parts of motor, particularly relates to a kind of end hoop of new structure.

Background technology

Along with Dui Di center, market is high, the increase in demand of large-size machine, low center is high, large-size machine research and development of products is very urgent.2P large-size machine winding terminal minister, considers the cooling needs that ventilate, and needs mounting block aerofoil on stator, and to realize the reasonable distribution to winding overhang and air quantity unshakable in one's determination, and it is cooling for ventilating on support, to need to design certain space; This kind of structure certainly will cause 2P motor under identical support length, and capacity motor design is less, and capacity cannot improve.Traditional 2P motor winding generally adopt twice steel end hoop or one steel end hoop with together with tie be fixed, this case changes the end hoop of winding far-end unshakable in one's determination into Novel end hoop, cancel the deep bead in stator, Novel end hoop has deep bead function concurrently, realizes the reasonable distribution to winding overhang and air quantity unshakable in one's determination.

Utility model content

The utility model has overcome to be needed on 2P motor stator traditional in prior art on mounting block aerofoil and support, to need to design certain cooling space, cause under identical support length, capacity motor design is less, capacity cannot improve problem, and a kind of end hoop of new structure simple in structure, easy to use is provided.

Technical solution of the present utility model is, provide a kind of end hoop of the new structure with following structure: contain annular hoop body, hoop body is axially evenly equipped with multiple through holes, the outermost anchor ring of hoop body is evenly equipped with multiple grooves, described hoop body is saw body, the right-angle side anchor ring that the outmost turns of hoop body is prismatoid.The axis of groove and hoop body is parallel, and the annulus at through hole place and the axis of hoop body are coaxial.

Compared with prior art, the end hoop of the utility model new structure has the following advantages: (1), identical with traditional support length in the situation that, capacity motor promotes 4 gears, and it is obvious that capacity provides; (2) Novel end hoop dual-use material, reduces number of spare parts, and motor efficiency of assembling is provided; (3) Novel end hoop only adopts a kind of insulating material, and simple in structure, machine work shaping; The manufacturing process of more traditional steel end hoop is simpler, and production efficiency is provided; (4) guaranteeing that motor ventilates under cooling condition, improving the design of stator wind path, making full use of support space, improving the design capacity of 2P motor.

Accompanying drawing explanation

Fig. 1 is the overall structure schematic diagram of the end hoop of the utility model new structure;

Fig. 2 is A-A ' structural representation in the utility model Fig. 1;

Fig. 3 be the utility model new structure end hoop install and use structural representation.

Embodiment

In accompanying drawing explanation, label 1 is hoop body, the 2nd, and groove, the 3rd, through hole, the 4th, support, the 5th, winding.

Below in conjunction with the drawings and specific embodiments, the end hoop of the utility model new structure is described further: as shown in the figure, the present embodiment contains annular hoop body 1, hoop body 1 is axially evenly equipped with multiple through holes 3, the outermost anchor ring of hoop body 1 is evenly equipped with multiple grooves 2, described hoop body 1 is saw body, the right-angle side anchor ring that the outmost turns of hoop body is prismatoid.Groove 2 is parallel with the axis of hoop body 1, and the annulus at through hole 3 places and the axis of hoop body 1 are coaxial.2P large-size machine winding 5 end length put in the macropore in the middle of end hoop, and have deep bead function concurrently, realize the reasonable distribution to winding 5 ends and air quantity unshakable in one's determination.
