Electrically operated screw-type jack
An electrically operated screw-type jack comprising a support base, a housing, a jack body, a lifting ram which is contained in the jack body, a servo motor which is contained in the housing, reduction gears for transmitting the driving power of the servo motor to the lifting ram, a safety device tp prevent the servo motor and the power transmitting mechanism from an abrupt failure due to overloading , and a square head pin for conventional hand operation of the jack when the jack is overloaded. The safety device consists of a clutch disk, a clutch spring and a sleeve. The reduction gears consist of first sun and planet gears, second sun and planet gears and a sun gear cylinder.
The components of the jack are:
-support base.
-jack body mounted on support base
-housing mounted on jack body,having a flange formed at a middle portion.
-servo motor having a driving gear mounted to a lower end .The servo motor is contained in the housing.
-lifting ram vertically mounted on the support base.
-driven gear and a driven pinion mounted on the support base. The pinions are engaged into each other.
-Reduction gears having first sun and planet gears including first planet gears and a center gear, second sun and planet gears including second planetary gears and a driving pinion, a sun gear cylinder housing.
-safety device mounted under the reduction gears, which has a clutch disk on which there are fitting recesses.
-clutch spring resiliently supporting the clutch disk in engagement with the lower end of sun gear cylinder.
-sleeve mounted detachably to the flange of the housing by bolts.
