Embodiment Construction

[0027] 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.

[0028] like Figure 1 to Figure 6 In one embodiment of the crane wheel of the present invention shown, the crane wheel of this embodiment includes a cylindrical hub 10, one side of the hub 10 is fixed with a circular shaft seal end cover 11, and the other side of the hub 10 is fixed. An annular shaft seal retaining ring 12 is fixed on the 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. The planetary deceleration module includes a central rotating shaft 20, a first-level planet carrier 21, The secondary planetary carrier 22, the primary sun gear 31 and the secondary sun...

Abstract

The invention relates to a crane wheel which comprises a cylindrical hub, a circular shaft seal end cover is fixed to one side of the hub, an annular shaft seal baffle ring is fixed to the other side of the hub, an inner gear ring is arranged on the inner surface of the hub, and a planetary speed reduction module is arranged in the hub. The planetary speed reduction module comprises a central rotating shaft, a first-stage planet carrier, a second-stage planet carrier, a first-stage sun gear and a second-stage sun gear, and planet gears on the first-stage planet carrier and the second-stage planet carrier are meshed with an inner gear ring of the hub; the inner gear ring is arranged on the inner surface of the hub, the planet wheels on the first-stage planet carrier and the second-stage planet carrier are both engaged with the inner gear ring of the hub, so that the output shaft of the driving motor drives the hub to rotate through two-stage planet speed reduction, and the structure of the wheel is compact through the mode that the planet speed reduction module is integrated in the hub; the size of a crane traveling mechanism can be effectively reduced, so that the crane wheel is compact in structure.

Description

technical field [0001] The present invention relates to hoisting machinery, in particular to a hoist wheel. 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, as disclosed in Chinese Patent Document No. CN206288863U, "Truck Running Mechanism and Crane", a transmission gear is fixedly sleeved on the wheel shaft of the traveling wheel, and a bridge gear is arranged between each adjacent transmission gear, and the bridge gear is fixed. On the bridge gear ...
