[0079] First, a biaxial output servomotor 150A according to an embodiment of the present invention will be described. figure 1It is a side view of 150 A of two-axis output servo motors. The dual-shaft output servomotor 150A is a high-output (37 kW rated output) ultra-low inertia servomotor provided with two output shafts 150A2a and 150A2b. The dual-axis output servo motor 150A includes a body frame 150A1, a drive shaft 150A2, a first bracket 150A3, and a second bracket 150A4.

[0080] The main body frame 150A1 is a substantially cylindrical frame, and a stator (not shown) having a coil is provided on the inner periphery thereof. A first bracket 150A3 and a second bracket 150A4 are attached to both ends of the body frame 150A1 in the axial direction so as to close the opening of the body frame 150A1 . A motor box is formed by the body frame 150A1, the first bracket 150A3 and the second bracket 150A4. Bearings 150A3b and 150A4b that rotatably support drive shaft 150A2 are pro...

Abstract

This two-output-shaft motor is equipped with: a cylindrical main frame; a substantially plate-like first bracket that is attached to one axial end of the main frame; a substantially plate-like second bracket that is attached to the other axial end of the main frame; and a drive shaft that runs through the hollow part of the main frame, penetrates through the first bracket and the second bracket, and is rotatably supported by bearings provided in the first bracket and the second bracket. One end of the drive shaft protrudes to the outside from the first bracket and forms a first output shaft for outputting a driving force to the outside, and the other end of the drive shaft protrudes to the outside from the second bracket and forms a second output shaft for outputting the driving force to the outside.

Description

technical field [0001] The present invention relates to a two-shaft output motor (two-outpt-shaft motor), a motor unit in which a plurality of motors including the two-shaft output motor are connected in series, a torsion testing device (torsion testing device) equipped with a two-shaft output servo motor, a rotary Rotational torsion testing device, tire testing device, linear actuator and vibration device. Background technique [0002] The inventors of the present invention have adopted an ultra-low inertia servo motor (inertia servo motor) that greatly reduces the inertia of conventional servo motors, enabling various fatigue tests of servo motors that apply high-frequency repetitive loads of several 10 to several 100 Hz A device and a vibration tester are put into practical use (for example, Patent Document 1). [0003] The above-mentioned servo motor type test device solves many serious problems existing in the existing oil pressure test device (for example: large-scale...
