Description
Technical field
The utility model relates to field of ocean engineering more particularly to a kind of self-elevating ocean platform seawater lift pump towers
Driving device.
Background technique
Seawater lift pump tower is one of the key equipment on self-elevating ocean platform, is all water cooling equipment cooling waters of platform
Exclusive source, once this device and ancillary equipment failure, will affect the safety or production services of platform.Jack up seawater
Elevator pump tower is typically designed to 2 ~ 3 mouthfuls of wells, and immersible pump is mounted on the bottommost of pump tower.When routine work, according to the depth of water and platform
Air gap height, seawater lift pump tower drop to suitable position.When platform declines towage operation, seawater lift pump tower is needed with flat
Platform synchronization action, is all retracted to hull.Therefore, the design type of seawater lift pump tower has important shadow to hoistable platform operation
It rings.
It is traditional cycloidal planetary gear speed reducer or parallel axes that self-elevating ocean platform seawater lift pump tower, which uses, at present
Transmission speed reducer, because it is in the case where Same Efficieney and equality strength require, slowing down power(SDP) is limited, and bulky, is self-possessed larger,
It is difficult to adapt to the requirement of self-elevating ocean platform, i.e. starting frequently, starts fast speed, the long feature of service life.
Utility model content
It is small in size the purpose of this utility model is to provide a kind of slowing down power(SDP) is strong, from the self-elevating ocean platform of heavy and light
The driving device of seawater lift pump tower, to improve the service ability of sea water pump tower.
The purpose of this utility model is achieved through the following technical solutions: a kind of driving device of seawater lift pump tower,
It includes and the level-one gear with small teeth difference group of motor output shaft transmission connection, the second level with the transmission connection of level-one gear with small teeth difference group
Planetary gear set and the climbing gear axis being sequentially connected with secondary planetary gear group；The level-one gear with small teeth difference group includes
Few teeth difference pivoted frame, internal gear being sequentially connected with motor output shaft, being mounted on few teeth difference pivoted frame, and mutually nibbled with internal gear
The external gear of conjunction；The secondary planetary gear group includes planet carrier, and the mode being splined and few teeth difference pivoted frame are sequentially connected
Sun gear, and multiple planetary gears being mounted on planet carrier；The planet carrier is connected by spline and the transmission of climbing gear axis
It connects, will be exported by the power of double reduction by climbing gear axis, to drive the elevating movement of pylon.
Further, the climbing gear axle position is in installation frame, the installation frame and secondary planetary gear group
Shell is fixedly connected, and the shell of the secondary planetary gear group is connect with the external gear of level-one gear with small teeth difference group.
Further, the output shaft connection of the motor has brake device for electrical machinery.
Further, the tooth difference of the internal gear and external gear of the level-one gear with small teeth difference group is 2, transmission ratio 58.
Further, the secondary planetary gear group uses NGW type planetary gear pair, and planetary gear number is three, second level
The resultant gear ratio of planetary gear set are as follows: 5.7.
The utility model uses level-one gear with small teeth difference group and secondary planetary gear group, has given full play to less teeth difference transmission ratio
Greatly, compact-sized, Gear Planet Transmission large carrying capacity, volume and the low advantage of quality is small, smooth running, noise.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the embodiments of the present invention.
Fig. 2 is the layout drawing of the utility model secondary planetary gear group.
Specific embodiment
The utility model technology contents are understood in order to clearer, and spy lifts following instance and is described in detail.
As shown in Figure 1 and Figure 2, the technical scheme adopted by the utility model is a kind of driving of seawater lift pump tower fills
Set, comprising: climbing gear axis 1, secondary planetary gear group 2, sun gear 3, level-one gear with small teeth difference group 4, output shaft 5, motor 6,
Installation frame 7, planet carrier 8, planetary gear 9, few teeth difference pivoted frame 10, internal gear 11, external gear 12.Wherein climbing gear axis 1 is located at
In installation frame 7, climbing gear axis 1 is connect by spline with the planet carrier 8 in secondary planetary gear group 2, secondary planetary gear
3 planetary gears 9 are separately connected on the planet carrier 8 of group 2, planetary gear 9 engages the sun gear 3 of secondary planetary gear group 2, sun gear 3
The few teeth difference pivoted frame 10 of level-one gear with small teeth difference group 4 is connected by spline, level-one gear with small teeth difference group 4 connects input shaft 5, level-one
