却能力に限界がある。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a liquid cooling structure for a motor, and in particular, it relates to a liquid cooling structure for a motor. Problems to be Solved] Cooling a motor from the outside with liquid has been conventionally practiced. However, as a recent trend, there is a strong desire to make motors smaller. In response to this demand, if an attempt is made to obtain a high output equal to or higher than the conventional one, a high amount of heat is inevitably generated. In such cases, there is a limit to the cooling capacity of conventional external liquid cooling alone.
そこで本発明は、モータを内部側から液冷する構造の提
供を目的とする。Therefore, an object of the present invention is to provide a structure in which a motor is liquid-cooled from the inside.

するモータの液冷構造を提供する。In view of the above object, the present invention provides a rotary shaft of a hollow cylinder with a closed end of a through hole centered on the central axis of rotation, and a hollow cylinder that is inserted into the through hole and arranged concentrically with respect to the rotary shaft. a pipe member having an outer diameter dimension smaller than the radial dimension of the fixed through hole; a rotating joint attached to the rear end of the pipe member; and a radial direction of the rear end of the output shaft. an outlet hole extending through the outlet hole, a sump chamber for accommodating the coolant discharged from the outlet hole, and a fringer on the rear side adjacent to the housing to seal leakage of the coolant in the sump chamber. A liquid cooling structure for a motor is provided, characterized in that it is equipped with a sealing means.

にシール手段を必要とする。The cooling liquid is fed from the rear part of the pipe member through the rotating joint, and flows into the front part of the rotating shaft, which is a hollow cylinder with a closed tip, and the inflowing cooling liquid connects the through hole of the rotating shaft with the outer surface of the pipe member. It flows backward through the flow path formed between them. At this time, the cooling liquid can cool the rotating shaft as well as the rotor. The liquid that has cooled the motor from the inside returns to the rear end of the rotating shaft, and is discharged into the liquid reservoir chamber from the outlet hole formed through the rotating shaft in the radial direction. The cooling liquid in this liquid storage chamber may be recovered through a suitable discharge pipe or the like, but a sealing means is required between the cooling liquid and the rotating shaft.

〔実施例］
以下、本発明を添付図面に示す実施例に基づいて更に詳
細に説明する。まずモータを内部から冷却する１つの実
施態様を第２図を用いて説明する。[Example] Hereinafter, the present invention will be described in further detail based on an example shown in the accompanying drawings. First, one embodiment of cooling the motor from the inside will be described with reference to FIG.
モータのロータには回転中心軸線を中心線として設けら

して、作業用の主軸２６に連結されている。The rotor of the motor is integrated with a hollow cylindrical rotating shaft 16 having a through hole 16 provided with the center axis of rotation as the center line, and rotates inside the stator 10 . The front housing 18 of the motor is secured to a suitable fixing structure 22. The rotating shaft 14 is connected to a working main shaft 26 via a hollow coupling member 24.

転軸１４の後端に接続させればよい。This main spindle 26 is used to supply cooling air into the machining chamber of the workpiece being machined by a tool attached to the tip of the main spindle, for example, when forming a deep hole in a workpiece using a machine tool. The air tube that cools the rotating shaft 14 and rotor 12 is formed into a hollow shape to collect the liquid. Therefore, the tool at the tip is also provided with a through hole. In order to send cooling air or coolant into the through hole 16 of the rotating shaft 14 of the motor, a well-known rotating joint 20 may be connected to the rear end of the rotating shaft 14.
深穴加工の際に、周囲から加工穴に対して冷却液（切削
液）を流入させようとしても、加工場所である底部まで
は十分に浸入しない。従って、上述した構成により、軸
内部から供給すれば冷却液は十分に供給が可能となる。When deep hole machining, even if an attempt is made to cause cooling fluid (cutting fluid) to flow into the machined hole from the surroundings, it will not sufficiently penetrate to the bottom, which is the machining location. Therefore, with the above-described configuration, it is possible to sufficiently supply the cooling liquid by supplying it from inside the shaft.
この際、主軸に直結されたモータの回転軸自体も、また
ロータ１２も冷却され、延いては主軸並びに工具の温度
上昇も低減できる。At this time, the rotating shaft of the motor directly connected to the main shaft as well as the rotor 12 are cooled, and the rise in temperature of the main shaft and the tool can also be reduced.

の回収構造に特徴を有する。FIG. 1 shows a cooling structure that cools only the motor from the inside. In the motor cooling embodiment shown in FIG. 1, the tip of the rotary shaft 14 of the motor is closed, so that the coolant recovery structure is unique.

体冷却される。The rotating shaft 14, which has a through hole 40 centered around the rotation center axis CI, is integrally formed with the rotor 12, and is rotatably supported by the stator 10 via front and rear bearings 60. Furthermore, a detector 54 for detecting the rotation of the rotating shaft 14 is attached to the rear end of the motor, and the stator 10 is externally liquid cooled by a conventional oil jacket 32.

is inserted, and the pipe member 30 is attached to the bracket 36
is fixed concentrically to the rotating shaft 14 by
The pipe member 30 is held by two or more annular members 34 so as to maintain a concentric position with the rotation axis I4. Further, holes are provided in the outer circumferential portion of these annular members 34 in several axial directions as appropriate, so that the cooling liquid can pass therethrough.

The cooling liquid fed into the pipe member 30 through the pipe member 30 flows out from the pipe member 30 near the front end 37 of the rotating shaft 14, and
The water flows rearward through an annular flow path formed by the outer circumferential surface of the pipe member 30 and the through hole 40 of the rotating shaft 14 . At this time, the rotating shaft 14 and rotor 12 are cooled. Then, it returns to the rear end of the motor and is discharged out of the rotary shaft 14 through a through hole 44 formed radially through the rear end portion 42 of the rotary shaft 14 . When discharging this coolant, in addition to the supply pressure of the coolant, centrifugal force due to rotation also makes a large contribution. The coolant discharged in this way is temporarily stored in a liquid reservoir chamber 46 formed by an annular housing 62 that surrounds the outer periphery of the rear end portion 42 of the rotating shaft 14 with a gap.

る。Although both sides of the liquid reservoir chamber 46 in the axial direction are sealed by oil seals 56, some liquid leakage may occur depending on various conditions. The above-mentioned rotation detector 54 is provided in a position close to this liquid reservoir chamber 46, and it is necessary to prevent the coolant from entering into the accommodation housing 66 thereof. Therefore, in the present invention, the oil seal 5
6 and the accommodation housing 66, a simple-shaped annular plate called a fringer 50 is attached to the rotating shaft 14. This fringer 50 rotates together with the rotating shaft 14,
The centrifugal force shakes off the coolant leaking from the oil seal 56, thereby completely blocking the coolant from entering and influencing the rotation detector 54. The coolant thus shaken off is discharged to the outside from the lower drain 52.

る。Incidentally, reference numeral 58 is an oil seal, and since the front side of the motor is in the working atmosphere, this prevents oil and the like in the atmosphere from entering the motor. That is,
It is clear that the front end 37 of the rotary shaft 14 can be connected to the main shaft of a normal machine tool by a normal coupling member, and that conventional work can be performed. This improvement makes it possible to perform high-load work. Furthermore, even when there is no rotation detector 54,
It is likewise possible that the action of the fringer 50 prevents the ingress of coolant into the rear housing 68.

いは結合部材に何らの変更も要しない。As is clear from the above description, according to the present invention, an inexpensive pipe member is used and a relatively large diameter through hole is provided in the rotating shaft, so processing is relatively easy. A seal can be ensured by using a jar,
Overall, a low-cost liquid cooling structure can be provided. In addition, since the coolant flows in and out only at the rear of the motor, the front end of the rotating shaft is exactly the same as in the case of a motor without a cooling structure, and there is no need to connect the main shaft or coupling member directly to the rotating shaft of the motor. No changes required.
