Description

ситета, но с предварительно установленным на величинуШсц ентриеитета смещением в сторону оси вращени передаточного механизма 12.of the committee, but with a pre-set value of the Shtententrietiya offset towards the axis of rotation of the transmission mechanism 12.

Аналогично осуществл етс взаимодействие диска 13 с роликом 15 его торцевой поверхностью.Similarly, the disk 13 interacts with the roller 15 with its end surface.

Таким образом применение контактных роликов дл создани вибровозбуждений в испытуемом передаточном механизме упрощает конструкцию стенда и позвол ет снизить энергозатраты1наг проведение испытаний .Thus, the use of contact rollers to create vibrational excitations in the tested transmission mechanism simplifies the design of the test bench and reduces the energy consumption of the tests.

Подбира контактные диски с разными диаметрами, эксцентриситетами их установки можно получить широкий спектр вибровозбуждений , перекрывающий весь диапазон условий эксплуатации.Selecting contact disks with different diameters, eccentricities of their installation, you can get a wide range of vibration excitations, covering the entire range of operating conditions.

Claims

1. A test bench for the transmission gears of the traction drive in the Big BOB tin, containing mounted on the base of the drive and load

electric motors connected to their shafts of the device for connecting to the respective end parts of the gear mechanism and the loading device

the latter, characterized in that, in order to simplify the design, said loading device includes a disk for installation with the possibility of longitudinal movement and fixing on the intermediate part of the tested gear mechanism and mounted on the base with the possibility of fixation relative to it and moving parallel and perpendicular to the axis the rotation of the specified mechanism rollers, one of which is installed with the possibility of interaction of its peripheral surface with the peripheral surface of the disk, and goy - with the end surface of the disk.

2. A stand according to claim 1, with the exception that said rollers and a disk are made with eccentric peripheral surfaces.
