Method for assembling and filling rotors of electric motors

专利摘要:
An electric motor rotor assembly and method of forming the flat rotor wherein an inner tubular casing and a commutator are molded in a first mold thereby forming between the casing and the commutator a molded resin intermediate section. After the so molded commutator is removed from the first mold, the windings for the rotor are first cold crimped and then hot crimped to the commutator thereby breaking the insulation and providing a good electrical connection. After the windings are attached to the commutator, it can then be tested to check the windings for electrical continuity. After the testing, the assembly is placed into a second mold where resin is injected about the windings forming a resin enclosing sheath.

The invention relates to the manufacturing technology of flat rotors of electric motors and can be used in the electrical industry.
The purpose of the invention is the simplification of technology.
In Fig.1 shows an intermediate · casting mold with a mounted collector and a collector sleeve; figure 2 - connection of the winding with the collector; figure 3-7 - the process of connecting the winding with the collector in two stages; on Fig - casting form with a mounted collector and winding.
The manufacture of a flat rotor of an electric motor is carried out in the following technological sequence.
In the intermediate casting mold 1 having a cavity for arranging the outer supporting surface 2 of the manifold 3 and an annular cavity 4 for arranging the collector sleeve 5 of the rotor, the collector 3 and the collector sleeve 5 are installed with a predetermined angular location 5. The predetermined angular location of the collector relative to the collector the sleeves are provided in the intermediate casting mold 1 by means of at least one pin or pin 6 connected to the mold and extending into the hole 7 of the sleeve 5 and one or more pins or Altsov 8, connected to form 1 and included between the collector plates.
To fix the sleeve 5 and the manifold 3 in the form 1, three evenly spaced pins or fingers 6 and 8 are provided.
In the recess 9 made on the inner surface of the collector 3, there is a reinforcing ring 10 of the collector 3, coated with fiberglass impregnated to facilitate gluing with the casting resin 11.
Then, resin 11 is poured into the annular space formed by the manifold 3, cap 1.2, the intermediate casting sleeve and the mold wall 1. Resin 11 can be filled with heat-conducting elements, for example, carbon, to improve the removal of radiated heat directly from the collector to the drive shaft during engine operation.
Then, the hub-collector assembly is removed from the mold 1 for connecting the winding 13 to the pre-filled collector 3 (FIG. 2).
The connection of the winding with the collector is carried out in two stages, namely: cold running using a stamping or a similar mechanism, then hot running under pressure using a machine designed to achieve cracking of the insulating material of the wires at the level of running without chemical or mechanical cleaning wires and low temperature soldering.
Then, the separation of the collector plates is carried out in a known manner and the collector 3 with the winding 13 at this stage can be placed in a control unit or rotor testing machine to detect possible defects in electrical circuits.
Then, the collector 3 with the winding 13 is installed in the casting mold (Fig. 8) containing the lower part 14 with a cavity 10 for accommodating the collector-sleeve-winding assembly and the upper part 15 with a profile corresponding to the profile of the assembly and having one or more pins on one side 16 or the fixing fingers of the collector sleeve 5, as in the first form, and, on the other hand, one or more mounting wedges 17, intended for fixing at an angle of the turns of the winding relative to the pins 16 (dashed lines in figure 2).
Then, resin 18, similar to resin 11, is introduced into the casting mold and, after curing, the manufactured flat rotor is removed.
The invention allows automatic adjustment of the position of the winding relative to the collector plates of the collector during the manufacturing process of the rotor and to ensure control of the winding before casting, which allows repair or rejection of the unfinished rotor with less loss.

The invention relates to the technology of manufacturing flat rotors of electric motors and can be used in electrical engineering. The purpose of the invention is to simplify the technology. Fig. 1 shows an intermediate casting mold with a mounted collector and a collector sleeve; in FIG. 2 a connection of a winding with a collector; 3-7 shows the process of connecting the winding to the collector in two stages; Fig. 8 — a filling mold with an installed collector and a winding. The production of a flat rotor of an electromotor is carried out in the following technological sequence. Into the intermediate casting mold 1, having a cavity for positioning the outer bearing surface 2 of the collector 3 and an annular cavity 4 for arranging the collector sleeve 5 of the rotor, a collector 3 and a collector sleeve 5 are set (Fig. 1) with the predetermined angular position The position of the collector relative to the collector sleeve is provided in the intermediate casting mold 1 by means of at least one pin or finger 6 connected to the mold and the sleeve 5 passing through the hole 7 and one or several pins or fingers 8 connected to form 1 and entering between the collector plates. For fixing the sleeve 5 and the collector 3 in the form of 1 there are three evenly spaced pins or fingers 6 and 8. In the recess 9, made on the inner surface of the collector 3, there is a reinforcing ring 10 of the collector 3, covered with fiberglass, impregnated with resin 11. Then, resin 11 is poured into the annular space formed by the collector 3, the lid 1.2, the intermediate casting sleeve and the wall of the mold 1. Resin 11 can be filled with heat-conducting elements, for example, carbon to improve the water direct heat radiated directly from the collector to P14ivodnomu shaft during engine. Then the sleeve-collector assembly is removed from the mold 1 to effect the connection of the winding 13 on the pre-filled collector 3 (Fig. 2). The winding is connected to the collector in two stages, namely: running in a cold state using a checker or similar mechanism, then running in a hot state under pressure using a machine designed to achieve cracking of the insulation material of the wires at the run-in level without chemical or mechanical cleaning of wires and low-temperature soldering. Then, the collector plates are separated in a known manner and the collector 3 with the winding 13 at this stage can be placed in a control installation or a rotor testing machine to detect possible defects in the electrical circuit. Then the collector 3 with the winding 13 is installed in the filling mold (FIG. 8) containing the lower part 14 with a cavity 10 for placing the collector-sleeve-winding node and the upper part 15 with a profile corresponding to the profile of the node and having on one side one or more pins 16 or fixing fingers of the collector sleeve 5, as in the first form, and, on the other hand, one or several adjusting wedges 17, intended to fix the windings relative to the pins 16 at an angle (dashed lines in FIG. 2). t resin 18, anal The composite resin 11 and after its curing, the manufactured flat rotor is taken out. The invention allows automatic control of the position of the winding relative to the collector plates of the collector during the manufacture of the rotor and control of the winding before pouring it, which allows repair or culling of the unfinished rotor with less losses.
