Abstract
A drive unit for a molding machine for longitudinally displacing a movable first machine component relative to a second machine component, includes a rotationally drivable spindle mounted in a linear movement-locking manner on the second machine component, a spindle nut arranged in a rotational movement-locking manner on the first machine component for positive-locking engagement with the spindle, and a fluid chamber which at least adjoins the spindle and/or the spindle nut, and contains a lubricant. A temperature control element for controlling the temperature of the lubricant is arranged in and/or on the fluid chamber at least in areas.
Claims28
A drive unit for use in a molding machine for longitudinally displacing a movable first machine component relative to a second machine component, the drive unit comprising:
- a rotationally drivable spindle mounted in a linear movement-locking manner on the second machine component;
- a spindle nut arranged in a rotational movement-locking manner on the first machine component for positive-locking engagement with the spindle;
- a fluid chamber adjoining at least one of the spindle and the spindle nut, the fluid chamber containing a lubricant;
- and
- a temperature control element configured to control the temperature of the lubricant in the fluid chamber, the temperature control element being arranged at least partially in and/or on the fluid chamber, the temperature control element including a sleeve at least partially surrounding at least one of the fluid chamber, the spindle, and the spindle nut.
