Description

Technical Field

[0001] The utility model relates to the technical field of conveyors, in particular to a mobile rotary drive mechanism. Background Art

[0002] Mobile conveyors can be divided into two types: those that require external traction and those that are self-propelled. For self-propelled conveyors, the tires need to be able to turn as needed. Usually, a drive device is connected to a gear to drive the slewing bearing to rotate. The slewing bearing is connected to the wheel seat to drive the tire to rotate. However, this structure requires high machining accuracy and is costly. Therefore, we have introduced a new mobile conveyor slewing drive mechanism. Utility Model Content

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model adopts a driving method of a driving sprocket, a rotating sprocket group and a chain. The rotating sprocket group adopts two types of bearings, namely a thrust spherical roller bearing and a tapered roller bearing, which can withstand radial force and axial force. Compared with other rotary drive mechanisms, it has lower processing accuracy requirements and lower costs, and is more suitable for light mobile conveyors. BRIEF DESCRIPTION OF THE DRAWINGS
