Abstract
The utility model discloses a motor stator coil end portion glue sealed structure. The motor stator coil end portion glue sealed structure comprises a pull plate; a motor stator with a water-cooled casing is arranged on the pull plate; the inner circle of the motor stator is tangent to a funnel-type pull plate; the funnel-type pull plate is fixed with the pull plate through a connecting piece; a stator coil is sleeved on the motor stator; and a gap between an end portion of the stator coil and the base of the water-cooled casing is filled with a sealing body. With the motor stator coil end portion glue sealed structure of the utility model adopted, the problem of high temperature of an end portion of an existing motor stator coil, which is caused by a situation in which the end portion of the existing motor stator coil transfers heat by means of air, can be solved; and at the same time, a winding can be separated from other chemical substances, and therefore, corrosion of the insulation of the winding can be avoided.
Description
Technical field
The utility model belongs to motor process technical field, is specifically related to a kind of stator coils of motor end rubber seal structure.
Background technology
Existing alternating current motor is often with casing water-cooling pattern cooling motor, but stator coil end does not contact with casing conventionally, in the airtight space of stator coil end, part heat relies on stator core to pass to casing, all the other most of heats rely on air to transfer heat to casing, then lower the temperature to casing by water-cooled.Because the air coefficient of heat conduction is lower, heat transference efficiency is very poor, has caused that end winding temperature rise is too high, and more severe patient burns coil.In addition, common winding, after some chemical substance of contact, tends to chemically reactive, damages insulation.
Utility model content
The purpose of this utility model is to provide a kind of stator coils of motor end rubber seal structure, solved the high problem of stator coil end temperature that existing stator coils of motor end causes by air conduction heat transfer, also winding and other chemical substance can be separated, avoid corroding winding insulation simultaneously.
The technical scheme that the utility model adopts is: stator coils of motor end rubber seal structure, comprise arm-tie, on arm-tie, place the motor stator with water-cooled casing, the inner circle of motor stator and funnel type arm-tie are tangent, funnel type arm-tie is fixed by connector and arm-tie, on motor stator, cover has stator coil, and the gap between stator coil end and water-cooled casing support is filled with sealing body.
Feature of the present utility model is also, the tangent place of the inner circle of motor stator wherein and funnel type arm-tie is filled with thickness glue.
Funnel type arm-tie is wherein fixed by long bolt and nut and arm-tie.
The beneficial effects of the utility model are,
Adopt sealing glue material to fill space between motor stator coil end portion and casing, it is solidified, motor stator coil end portion and stator cage are become one.
Because the heat conductivity of curing sealing glue material is compared with much higher times of air, adopt after the solid winding overhang of sealing rubber seal, can directly by sealing body, most heat be passed to support, then be lowered the temperature by the cooling casing in the external world, thereby reach the effect of remarkable reduction motor stator coil end portion temperature rise.
Sealing body has also increased the mechanical strength of motor end, also winding and other chemical substance is separated simultaneously, prevents that winding from contacting with other material and cause insulation damages.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The structure of the utility model stator coils of motor end rubber seal structure, comprise arm-tie 8, on arm-tie 8, place the motor stator 1 with water-cooled casing 2, the inner circle of motor stator 1 and funnel type arm-tie 5 are tangent, tangent place is filled with thickness glue, funnel type arm-tie 5 is fixing with arm-tie 8 by long bolt 6 and nut 7, and on motor stator 1, cover has stator coil 3, and the gap between stator coil 3 ends and water-cooled casing 2 supports is filled with sealing body 4.
The course of work of the utility model stator coils of motor end rubber seal structure is:
As shown in Figure 2, arm-tie 8 is placed horizontally to platform, by water-cooled casing 2 motor stator 1(Fig. 1 of rubber seal not) stand upside down on arm-tie 8, funnel type arm-tie 5 is placed in to motor stator 1 inner circle tangent, with long bolt 6 and nut 7, funnel type arm-tie 5 is fixing with arm-tie 8, with thickness glue, by the space shutoff at tangent place, then to stator coil 3 ends and support gap, fill sealing body 4, it is solidified, after solidifying, dismounting funnel type arm-tie 5, long bolt 6, nut 7.
Press Fig. 3, stood upside down on arm-tie 8 in the good one end of motor sealing, by Fig. 2 method, motor stator 1 other end is encapsulated.Fig. 4 is the stator coils of motor end rubber seal structure that rubber seal completes.
