Definitions

the invention relates to a motor pump unit according to the preamble of the main claim.
a motor pump unit corresponding to the preamble is known from DE-OS 21 11 454. Its planetary gear acts as a transmission gear and, with its housing, also serves as a support lantern for a drive motor. To dampen vibrations, the central shaft of the transmission is provided with a vibration damper designed as an auxiliary bearing. This serves to compensate for shaft movements when starting off and during operation.
the invention has for its object to develop a low-cost, statically determined storage of the rotating parts for a submersible pump for pumping large amounts of liquid at low head.
This object is achieved in accordance with the characterizing part of the main claim.
This solution has made it possible to arrange the pump shaft with only one bearing within the pump housing and to form the second pump shaft bearing through the planetary gear housing due to the bending moment-transmitting coupling between the pump shaft and the output shaft of the planetary gear. Since the planetary gears usually have a large number of bearings within their housing, the forces acting on the pump shaft can be taken over and directed to the planetary gear housing.
the structural unit formed from the pump shaft and planetary gear thus has a fixed bearing within the pump housing and a floating bearing in the form of the planetary gear housing.
An embodiment of the invention provides that the drive motor is connected to the drive shaft of the planetary gear with the interposition of a flexible coupling. Static undetermined storage within the entire unit is thus excluded.
the drive motor is connected directly to the planetary gear housing and its drive shaft or is connected to the stationary ring gear and the drive shaft of the planetary gear.
the size of the unit can be significantly reduced and z.
the bearings used within the planetary gear and the fixed bearing of the pump shaft must be checked or designed.
a further embodiment of the invention provides that a stop cooperating with the housing of the planetary gear and attached to the pump housing or the lantern limits the axial movement of the gear housing.
the output shaft of the planetary gear is mounted in the area of the bearing plane of the planetary gear housing or the stationary ring gear.
a further embodiment of the invention provides that the torque support of the planetary gear housing or the stationary ring gear is designed to be shock-absorbing.
elastic stops such as. B. rubber buffers, spring assemblies, shock absorbers or the like. With which the planetary gear housing is secured against torque, are caused by the medium conveyed by the pump shaft impacts are reduced. The same applies to the loads that occur when the submersible pump unit starts up.
the planetary gear 5 is arranged between a pump shaft 4 provided with the axial propeller 3 and the drive motor 1.
the planetary gear 5, which forms a compact structural unit, consists of the drive shaft 6, which is connected to the drive motor 1 with the interposition of a flexible coupling 7.
the housing 8 of the planetary gear 5 is rigidly or elastically secured against rotation in the lantern 9 carrying the drive motor 1, but is mounted displaceably in the axial direction.
a rubber ring 10 arranged between the housing 8 and the lantern 9 serves to dampen vibrations and to seal an oil reservoir, which may be used, for cooling and lubrication purposes.
the output shaft 11 of the planetary gear 5 is in the middle of a bending moment-transmitting shrink connection 12 with the Pump worlds 4 connected.
the pump shaft 4 is fastened within the pump housing 2 in the radial bearing 13 and angular contact ball bearing 14 forming the fixed bearing. Due to the bending moment transmitting clutch 12 and the bearing within the planetary gear 5, the housing 8 of the planetary gear acts as a second pump shaft bearing, i. H. Floating bearing.
the submersible motor pump shown in FIG. 2 corresponds essentially to FIG. 1, only here the planetary gear 5 is open in the direction of the axial propeller.
the output shaft 11 forming the planet carrier is mounted here in the region of the bearing plane of the planetary gear. Additional moments in the transmission are thus negligibly kept to a minimum.
a seal attached between the output shaft 11 and the pump housing 2 makes it possible to fill the entire space 16 with oil. This measure can be used in those cases in which very large powers have to be transmitted from the planetary gear 5 and the oil quantity located within a closed planetary gear would therefore not be sufficient for cooling and lubrication. In addition to the reduction of the partial scope, this also means a reduced manufacturing effort.
FIG. 3 shows a particularly compact submersible pump unit in which a drive motor 17 which is directly coupled to the planetary gear 5 is used.
the weight of the drive motor in this case rests on the housing 8 of the planetary gear and it is a question of calculation to what extent the bearings used here are sufficient or have to be dimensioned differently.
the supply and discharge of the high-energy hydraulic fluid takes place via the lines 18. Rubber blocks 19 serve to support the torque.
