Abstract
Disclosed is a drive mechanism for driving a spin test rig, comprising a transmission casing (1) which accommodates a transmission gear unit (8) having a vertical output shaft (10) and an input shaft (9) coaxial therewith. The output shaft (10) has an upper end arranged in the transmission gear unit (8) and a lower end adapted to be coupled to a test object. The transmission casing (1) includes a casing lower part (4) detachable therefrom with the gear unit installed, in which casing part the output shaft (10) is axially and radially carried in bearings (28, 29) at a distance from its ends. The transmission gear unit (8) is configured such that the output shaft (10), together with the casing lower part (4) and the bearings arranged therein, is removable from the transmission casing (1).
Claims10
A drive mechanism of a spin test rig comprising a transmission having a transmission casing accommodating a transmission gear unit which has a vertical output shaft and an input shaft coaxial therewith,
- wherein the output shaft has an upper end associated with the transmission gear unit and a lower end adapted to be coupled to a test object,
- wherein the transmission casing includes a casing lower part that is detachable from the transmission casing while the transmission is installed in the spin test rig, and the output shaft is axially and radially carried in the casing lower part by bearings placed at a distance from the upper and lower end of the output shaft,
- wherein the bearings of the output shaft are completely arranged in the casing lower part, and
- wherein the transmission gear unit is configured such that the output shaft, together with the casing lower part and the bearings arranged therein, is removable from the transmission casing downwardly in the direction of the axis of the output shaft.
