Abstract
The utility model provides a split type five-planetary reducing mechanism applied to an elevating system of a self-elevating drilling platform. The split type five-planetary reducing mechanism comprises a primary sun gear, a secondary sun gear, an inner gear ring provided with teeth at the inner wall, five planetary gear groups, a planetary carrier and an output shaft. The primary sun gear, the secondary sun gear and the planetary gear groups are respectively arranged in the inner gear ring. The primary sun gear is fixedly connected with the secondary sun gear. The five planetary gear groups composed of two coaxial and mutually separated planetary gears are uniformly distributed around the secondary sun gear and are engaged with the teeth of the inner wall of the inner gear ring. The planetary carrier is fixedly connected at one side where the planetary gear groups are away from the primary sun gear. The output shaft is connected with the secondary sun gear. One end, close to the secondary sun gear, of the output shaft is provided with a tooth which is engaged with the planetary carrier. The other end is provided with a climbing gear capable of driving an elevating platform to elevate. The split type five-planetary reducing mechanism applied to the elevating system of the self-elevating drilling platform has following beneficial effects: bearing capability of the platform is enhanced; scope of variable loads is increased; and the split type planetary reducing mechanism facilitates transporting, hoisting and installing operation and is smoother in operation and smaller in noise.
Description
Technical field
The utility model relates to the technical field of lifting system of self-lifting well drilling platform, refers in particular to split type five planetary gear speed reducing mechanisms that are applied to lifting system of self-lifting well drilling platform.
Background technique
In prior art, planetary speed reducer majority is three planets or four lines star, the in the situation that of equal profile, the moment of torsion of three planets or the output of four lines star is little, the bearing capacity of platform and the scope of changing load are little, and in same category of device, lifting unit is heavier, the operations such as inconvenient transportation, lifting, installation, and move not steadily, noise is large, in addition, ring gear and sun gear discontinuity during rotation, the working life of reducing machine.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of reliable, split type five planetary gear speed reducing mechanisms that are applied to lifting system of self-lifting well drilling platform of operating steadily reasonable in design are provided.
For achieving the above object, technological scheme provided by the utility model is: split type five planetary gear speed reducing mechanisms that are applied to lifting system of self-lifting well drilling platform, it includes one-level sun gear, secondary solar gear, inwall is provided with the ring gear of teeth, five groups of planetary gear set, planet carrier and output shaft, wherein, one-level sun gear, secondary solar gear, planetary gear set is placed in respectively ring gear inside, one-level sun gear and secondary solar gear are fixedly connected, five groups of planetary gear set that are comprised of two planet wheels coaxial and disconnected from each other are evenly distributed on secondary solar gear surrounding and mesh with the teeth of ring gear inwall, planet carrier is fixedly connected on this planetary gear set away from a side of the first sun gear, and output shaft and the second sun gear join, and output shaft is provided with near one end of the second sun gear the teeth that are meshed with planet carrier, its the other end is provided with the climbing gear that drives lift platform lifting.
The utility model is after having adopted such scheme, the in the situation that of equal profile, the bearing capacity of platform and the scope of changing load have been increased, in same category of device, lifting unit is lightweight, has facilitated the operations such as transportation, lifting, installation, move more steady, noise is less, and ring gear and sun gear stressed more evenly rationally, avoided reduce the working life of machine.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.
Shown in accompanying drawing 1, split type five planetary gear speed reducing mechanisms that are applied to lifting system of self-lifting well drilling platform described in the present embodiment, it includes one-level sun gear 1, secondary solar gear 2, inwall is provided with the ring gear 3 of teeth, five groups of planetary gear set 4, planet carrier 5 and output shaft 6, wherein, one-level sun gear 1, secondary solar gear 2, planet wheel 4 is placed in respectively ring gear 3 inside, one-level sun gear 1 and secondary solar gear 2 are fixedly connected, when platform needs lift work, one-level sun gear 1 and secondary solar gear 2 rotations produce low-speed big, drive is evenly distributed on secondary solar gear 2 surroundings and rotates with five groups of planetary gear set 4 of the teeth engagement of ring gear 3 inwalls, each described planetary gear set 4 is comprised of two planet wheels coaxial and disconnected from each other, guaranteed uniform stressed between ring gear and sun gear, avoided reduce the working life of machine, in addition, described ring gear 3 is fixed, planet wheel 4 drives and is fixedly connected on it away from planet carrier 5 rotations in the first sun gear 1 one sides, and output shaft 6 and the second sun gear 2 join, and output shaft 6 is provided with near one end of the second sun gear 2 teeth that are meshed with planet carrier 5, the planet carrier 5 of rotation passes to output shaft 6 moment of torsion, moment of torsion finally passes to tooth bar by being arranged on the climbing gear 7 of the drive lift platform lifting of output shaft 6 the other ends, complete the lifting of platform.
The examples of implementation of the above are only the preferred embodiment of the utility model, not with this, limit practical range of the present utility model, therefore the variation that all shapes according to the utility model, principle are done all should be encompassed in protection domain of the present utility model.
