The device includes a workbench, a mounting bracket base, a upper pressure plate for the mounting bracket, a servo motor, a mounting fixed sleeve, a tested RV reducer, a temperature sensor, an extension arm, a simulated swing arm, two counterweight blocks named the first and second counterweight block, the first displacement sensor, a sensor holder, a sensor protector, a detection rod, and the second displacement sensor. The device is equipped with two counterweight blocks at the end of the simulated swing arm to simultaneously provide variable loaded torque and loaded bending moment to the RV reducer. The first displacement sensor is placed under the counterweight block to measure the positioning accuracy and repeat positioning accuracy of RV reducer. The second displacement sensor is placed under the detection rod to measure the bending stiffness of RV reducer. After running for a specified time, the precision retaining ability, fatigue life and wear rule of RV reducer are tested. The invention provides an experimental basis for theoretical research on the wear rule and accelerated life of RV reducer.

摘要： A first shaft segment and a second shaft segment are joined by a first fastener and a second fastener to form a shaft test assembly. The first shaft segment and the second shaft segment are each curved between first and second circumferential ends. A method of testing a shaft includes displacing a first applicator part relative a second applicator part to exert a load on the shaft test assembly. The resulting shear stress on the shaft test assembly can be measured to determine material properties of the shaft. A first applicator part extends at least partially into the shaft test assembly and interfaces with the first shaft segment to apply a load. A second applicator part extends at least partially into the shaft test assembly and interfaces with the second shaft segment to apply a load.

摘要： Friction disk sets of clutches and brakes are used, for example, in automatic transmissions. In clutch test benches for such clutches, the friction disks are held in a test chamber on inner and outer disk carriers. The test bench arrangement has a clutch unit which includes first and second disk carriers. The first disk carrier can be moved relative to the second disk carrier. A drive input section includes a drive input mechanism for producing relative movement between the first and the second disk carrier. A first driven shaft is mounted by at least one first bearing unit. The first disk carrier is drive-connected, via the first shaft, to the drive input mechanism. The first shaft is mounted to rotate by virtue of the first bearing unit. The test bench arrangement includes a measuring unit for determining a frictional torque of the first bearing unit.

摘要： A method for manufacturing a gear includes providing teeth which are shaped according to an epicyclic construction; wherein: locations on a respective tooth surface of each tooth are each determined by a radial distance from an axis as a function of a cycle angle; the radial distance is in turn determined by an equidistant to a gear trajectory; locations on the gear trajectory are respectively determined by the vector sum of a cycle vector and an epicycle vector; a tail of the cycle vector lies on the axis and a tail of the epicyclic vector lies in the tip of the cycle vector; an epicycle angle of the epicycle vector is n times as large as that cycle angle and a length of the cycle angle is greater than a length of the epicycle angle; and n is a number of the round engagement portions of the harmonic pin ring transmission which is at least three.
