Title:
ROTATION TESTING DEVICE
Document Type and Number:
Japanese Patent JP2019028041
Kind Code:
A
Abstract:
To provide a rotation testing device in which a middle shaft for rotatably connecting a rotational body and a sample is rotatably supported by a bearing, the rotation testing device allowing suppression of a reduction of detection accuracy of torque that the sample generates by reducing an influence of a temperature change of lubricant on a loss in the bearing.SOLUTION: A testing device for a vehicle 1 includes: a dynamo 11; a middle shaft 31 for rotatably connecting a sample motor 2 and the dynamo 11 to each other; middle shaft bearing parts 32 and 33 for rotatably supporting the middle shaft 31; a torque detection unit 41 for detecting torque generated between the sample motor 2 and the dynamo 11; a lubricant supply device 20 for supplying lubricant to bearings 32a and 33a of the middle shaft bearing parts 32 and 33; and a lubricant heating unit 35 provided at the middle shaft bearing part 32 which is located at a sample motor 2 side, the lubricant heating unit heating the lubricant supplied from the lubricant supplying device 20 to the bearing 32a of the middle shaft bearing parts 32.SELECTED DRAWING: Figure 1
