Embodiment Construction

[0028] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings and in conjunction with embodiments. It should be noted that the embodiments of the present invention and the features of the embodiments may be combined with each other under the condition of no conflict.

[0029] like Figure 1 to Figure 6 In the illustrated embodiment of the crane power assembly of the present invention, in the crane power assembly of this embodiment, the wheel includes a cylindrical hub 10, and a circular shaft seal end cover 11 is fixed on one side of the hub 10. An annular shaft seal retaining ring 12 is fixed on the other side, an inner gear ring 101 is provided on the inner surface of the hub 10, and a planetary deceleration module is installed in the hub 10, and the planetary deceleration module includes a central rotating shaft 20, a first-level planet carrier 21. The secondary planet carrier 22, the primary sun gear 31 and the secondary...

Abstract

The invention relates to a crane power assembly which is characterized in that a wheel comprises a cylindrical hub, an inner gear ring is arranged on the inner surface of the hub, a planetary speed reduction module is arranged in the hub, and the planetary speed reduction module comprises a central rotating shaft, a primary planet carrier, a secondary planet carrier, a primary sun gear and a secondary sun gear; planet gears on the first-stage planet carrier and the second-stage planet carrier are meshed with an inner gear ring of the hub; one end of the central rotating shaft is rotatably fixed in the center of the shaft seal end cover, the primary planet carrier and the secondary sun gear are both arranged on the central rotating shaft in a sleeving manner, the secondary sun gear is fixedly connected with the primary planet carrier, and a spiral oil guide blade corresponding to a central shaft hole of the secondary sun gear is further arranged on the central rotating shaft; the size of the crane walking mechanism can be effectively reduced; the spiral oil guide blades can enable lubricating oil on the two sides of the secondary sun gear to axially circulate, so that circulating flow of the lubricating oil in the wheel can be remarkably improved, and lubrication and heat dissipation are reliable in the rotating process of the wheel.

Description

technical field [0001] The invention relates to hoisting machinery technology, in particular to a hoist power assembly. Background technique [0002] The classification of cranes is very wide. The common classifications are single-girder cranes, double-girder cranes, gantry cranes, bridge cranes, double-girder gantry cranes, etc. There are traveling wheels, and the drive motor drives the traveling wheels to rotate through the reducer to realize the translation of the running mechanism and the traveling mechanism. The existing crane traveling wheels need to be equipped with a reducer, which makes the wheels larger and increases the difficulty of the crane structure design. [0003] For example, the Chinese patent document with the bulletin number CN207569151U discloses a "drive wheel" for a walking robot. The drive wheel hides the planetary reducer under the hub, reducing the overall volume and making the structure more compact; however, this Among the drive wheels disclosed...
