摘要： A device for driving the main shaft of a machine tool, in which the dimension of the device is small, occurrence of vibrations and noises can be controlled and a region of operation from rotation at low speed to rotation at high speed is wide. This device comprises a main shaft (42) rotatably supported in a main shaft housin (40), a variable speed driving motor (48) having a winding change-over mechanism and provided formed therein with a through-hole (44) extending in the axial direction, a coupling member (50) for directly coupling the main shaft (42) to the output shaft (46) which are coaxially arranged with each other, and ceramic bearings (52) for journally supporting the output shaft (46). The variable speed driving motor (48) includes a winding for low speed rotation and another winding for high speed rotation, which are changed over by the winding change-over mechanism, whereby the motor (48) is rotated at speeds different from each other. The coupling member (50) directly connects the main shaft (42) to the output shaft (46) to thereby transmit the rotational output of the variable speed driving motor (48) directly to the main shaft (42). The ceramic bearings (52) are held by the motor casing (49) of the variable speed driving motor (48) to thereby journally support the output shaft (46) without causing a seizure even during rotation at high speed. Further, the variable speed driving motor (48) has a liquid cooled construction.

摘要： This invention relates to a liquid cooling structure for cooling a motor from inside by causing a cooling liquid to flow inside a shaft (14) of the motor. The flow path of the cooling liquid is defined by an inexpensive pipe member (30) disposed inside a hollow shaft (14) and a through-hole (40) of the shaft which has an inner diameter greater than the outer diameter of the pipe member. The cooling liquid is caused to flow into the pipe member (30) from a rotary joint (20) at the rear part andthe cooling liquid that has returned to the rear part through the through-hole (40) is discharged into an annular liquid storage chamber (46) and from thence recovered to the outside. To insure seal at this time, a fringe (50) is disposed between a seal member (56) of the liquid storage chamber (46) and a rear housinmg (66) in addition to the seal member (56).

摘要： A jacket with passages (2) for cooling liquid is provided by extrusion of aluminum alloy billets. This product is used as a stator-cooling jacket, i.e. a motor casing (1). Front and rear cast-iron housings (4, 5) are fitted to the front and rear surfaces of the casing (1) with tie-bolts (10) to form a liquid-cooled motor. The flanges (14, 16) of the front and rear housings (4, 5) are provided with either holes for passing the tie-bolts (10) or female threads for receiving the male threads at the free end portions of the tie-bolts (10). The cross section of each lightening hole (11), formed during the casting of the casing (1) and utilized as a hole for passing the tie-bolt, is shaped so as to allow only the axial movement of the tie-bolt (10). The number of lightening holes (11) is four, for example, and they are positioned at regular intervals in the circumferential direction of the casing (1). The passages (2) for passing a cooling liquid through the interior thereof are provided on the left and right sides of each lightening hole (11), and a plurality of cooling fins (12) projecting inward are formed by precision machining in the lightening holes. Thus, the liquid-cooled motor and its jacket have improved reliability with respect to the leakage of the liquid, and an improved cooling efficiency. In addition, the number of manufacturing steps is decreased.

摘要： A support member (22) capable of holding a laminated core member having a predetermined axial length with opposite axial end faces of the core member held down is used to hold a small size laminated core member (24) having a smaller axial length and a spacing element (48) having a thickness substantially equal to the difference in axial length between these laminated core members and interposed between one axial end face of the laminated core member (24) and a cap element (32) of a support member (22). Then the laminated core member (24) and the spacing element (48) held by the support member (22) are received in a mold (20) which can form a conductor portion integrally with the laminated core member which is held by the support member (22) and has the predetermined length. With this position kept, molten metal is poured into slots (38) of the laminated core member (24) and annular spaces (44, 46) to solidify for integral forming of a conductor portion on the laminated core member (24).

摘要： A housing is made up of a thermally highly conductive casing (20) surrounding the outer periphery of a stator (16) of a multiphase induction motor, and front and rear frange (22, 24) for supporting bearings, which are coupled in a sealing way to the front and rear of the casing (20) respectively. A main pipe (60) and auxiliary pipes (40, 80) for a cooling liquid, through which cooling liquid is forced to flow are provided inside the housing. Thereby, the two kinds of heats, which are generated by the copper losses in the stator (16) and a rotor (12), and by the rotation in the bearings (14a, 14b) for an output shaft (10) of the rotor (12) are taken away.

摘要： When a high-speed motor is used to drive a spindle of a machine tool, machining accuracy will drop due to even a slight unbalance of rotating parts. Therefore, labyrinth formation disc members (22F, 22R) at the front and rear portions of a motor and a revolution detection gear member (24G) of an output shaft (14), which are inherent to the motor, are utilized. In other words, a plurality of screw holes (22A) are bored in advance on the outside surface of each of these members and balance adjustment is carried out by meshing a screw component (26) with the screw hole at a suitable position while measuring an unbalance quantity after the motor is assembled.
