Abstract

A torque load testing device is provided to prevent torsion torque of a driving shaft and an outer shaft from being zero although an alternation torque is loaded to a testing shaft. A torque load testing device comprises a driving shaft(1), a testing shaft(11), and an outer shaft(21). The driving shaft comprises first and second driving gears(6,7). The driving shaft is rotated with a rotary diving unit. The testing shaft comprises first and second testing gears(12,13), a test piece mounting unit(18), and a torque loading device(14) for the test piece. The torque loading apparatus for the test piece applies load torque on a test piece mounted on the mounting unit. The outer shaft comprises first and second gears(22,23) of the outer shaft and a pre-torque setting device(24). The pre-torque setting device sets pre-torque by relatively rotating the second gear of the outer shaft to the first gear of the outer shaft. The axis center of parts is arranged on the closed loop.

Description

technical field [0001] The present invention relates to a torque load test device capable of applying a load torque to a sample as a test object mounted on a test shaft. Background technique [0002] A conventional torque load test device is described in, for example, Patent Document 1 (JP-A-55-20415). The existing example Figure 8 As shown, the drive shaft 02 is rotated by the electric motor 01. The drive shaft 02 is provided with a drive shaft first gear 03 and a drive shaft second gear 04, and the gears 03, 04 pass through the intermediate gears 06, 07 and the test shaft 011 of the test shaft first gear 012 and the test shaft second gear. The second gear 013 meshes. A sample 016 as a test object such as a rotating shaft of a vehicle or a constant velocity joint is attached to the test shaft 011 . When the drive shaft 02 is rotated, the sample 016 is rotated by the aforementioned gear mechanism. Moreover, the drive shaft 02 is provided with a rotary transmission devic...
