The invention describes an arrangement of lubricating grease inside the housing of a gear unit with rotatable components, particularly the gear unit of a jack. It also describes a grease pouch for receiving lubricating grease and a method for lubricating the gear unit with lubricating grease. Since the gear units are often not transported in their installed position, oil that has separated from the lubricating grease may leak from any gearbox openings. Thus, one of the objects of the invention was to provide an arrangement of lubricating grease in the housing of a gear unit, which on the one hand provides lubrication of the gear unit so that it is ready for operation in its delivery condition and on the other hand effectively prevents the oil separated from the lubricating grease from leaking prior to initial startup. This object is attained by enclosing the lubricating grease within at least one grease pouch prior to initial startup of the gear unit. The at least one grease pouch is inserted into the housing of the gear unit so as to contact the components. Upon initial startup the at least one grease pouch is torn open by the action of the components and releases the lubricating grease.

The invention claimed is: 1. An apparatus having an arrangement of lubricating grease inside the housing of a gear unit, comprising: the gear unit having rotatable components, wherein, prior to the initial startup of the gear unit, the lubricating grease is enclosed by at least one grease pouch, wherein the at least one grease pouch is arranged in the housing of the gear unit wherein at least one face edge of the grease pouch lies in contact with at least a gear wheel of the rotatable component, wherein the lubricating grease is located in the gear unit of a jack, wherein the gear unit is at least partially arranged inside a gear chamber formed by a support tube and a gear cover, has a shaft configured with a first bevel gear, wherein the first bevel gear meshes with a second bevel gear that is non-rotatably mounted on the gear-side end of a spindle, and an inner tube supported in the support tube and engaging with the spindle via a spindle nut can be telescoped in an extension direction by a rotation of the shaft in a first direction of rotation, and wherein the grease pouch is inserted into the gear chamber with at least one edge on the first bevel gear or the second bevel gear or both the first bevel gear and second bevel gear. 2. An apparatus as claimed in claim 1, wherein the grease pouch is arranged in the gear chamber on a pull-in side of the bevel gears in the first direction of rotation. 3. An apparatus as claimed in claim 1, wherein the grease pouch has a width that largely corresponds to the diameter of the second bevel gear. 4. An apparatus as claimed in claim 1, wherein the at least one edge of the grease pouch is attached to at least one bevel gear or the intermediate shaft or both the bevel gear and intermediate shaft by means of an adhesive. 5. An apparatus as claimed in claim 1, wherein the edge of the grease pouch has a mounting tab that can be guided between the intermediate shaft and the second bevel gear. 6. An apparatus as claimed in claim 1, in which the gear cover on its underside has a protruding circumferential supporting rim and a protruding cross rib, wherein additional blocking ribs engage with the supporting rim and the cross rib. 7. An apparatus as claimed in claim 1, wherein the grease pouch is made of a composite material. 8. An apparatus having an arrangement of lubricating grease inside the housing of a gear unit comprising: the gear unit having rotatable components, wherein, prior to the initial startup of the gear unit, the lubricating grease is enclosed by at least one grease pouch, the at least one grease pouch is inserted into the housing of the gear unit so as to lie with at least one edge close to at least a gear wheel of the rotatable component, and the at least one grease pouch is caught by at least one edge and is pulled entirely into the gear unit and tears open during the initial startup because of the action of the rotatable components and releases the lubricating grease, wherein the lubricating grease is located in the gear unit of a jack, wherein the gear unit is at least partially arranged inside a gear chamber formed by a support tube and a gear cover, has a shaft configured with a first bevel gear, wherein the first bevel year meshes with a second bevel gear that is non-rotatably mounted on the gear-side end of a spindle, and an inner tube supported in the support tube and engaging with the spindle via a spindle nut can be telescoped in an extension direction by a rotation of the shaft in a first direction of rotation, and wherein the grease pouch is inserted into the gear chamber with at least one edge on the first bevel gear or the second bevel gear or both the first bevel gear and the second bevel gear. 9. An apparatus as claimed in claim 8, wherein at least one edge of the grease pouch is arranged on a gear wheel of the gear unit. 10. An apparatus as claimed in claim 8, wherein the grease pouch is arranged in the gear chamber on a pull-in side of the bevel gears in the first direction of rotation. 11. An apparatus as claimed in claim 10, wherein the grease pouch has a width that largely corresponds to the diameter of the second bevel gear. 12. An apparatus as claimed in claim 11, wherein the at least one edge of the grease pouch is attached to at least one bevel gear or the intermediate shaft or both the bevel gear and the intermediate shaft by means of an adhesive. 13. An apparatus as claimed in claim 12, wherein the edge of the grease pouch has a mounting tab that can be guided between the intermediate shaft and the second bevel gear. 14. An apparatus as claimed in claim 13, in which the gear cover on its underside has a protruding circumferential supporting rim and a protruding cross rib, wherein additional blocking ribs engage with the supporting rim and the cross rib. 15. An apparatus as claimed in claim 14, wherein the grease pouch is made of a composite material. 16. An apparatus as claimed in claim 8, wherein the grease pouch is arranged in the gear chamber on a pull-in side of the bevel gears in the first direction of rotation, wherein the grease pouch has a width that largely corresponds to the diameter of the second bevel gear, and wherein the at least one edge of the grease pouch is attached to at least one bevel gear and/or the intermediate shaft by means of an adhesive 17. An apparatus as claimed in claim 8, wherein the edge of the grease pouch has a mounting tab that can be guided between the intermediate shaft and the second bevel gear, wherein the gear cover on its underside has a protruding circumferential supporting rim and a protruding cross rib, wherein additional blocking ribs engage with the supporting rim and the cross rib, and wherein the grease pouch is made of a composite material.
