Load-balanced mud pump assembly

A load-balanced, high-capacity mud pump is provided. In some embodiments, load balancing is achieved by spacing hubs along the crankshaft of the mud pump with the bull gears disposed opposite one another, on outer ends of the crankshaft adjacent to the housing. In such an embodiment, the hubs are disposed along the crankshaft between the bull gears. A pinion shaft (or separate pair of shafts) canbe provided, mechanically supported in the mud pump by roller bearings or lubricated pads. Additional systems, devices, and methods are also disclosed. 本发明提供了负载平衡的高容量泥浆泵。在些实施方案中，通过沿着所述泥浆泵的曲轴将轮毂间隔开来实现负载平衡，其中大齿轮彼此相对地设置在所述曲轴的与外壳相邻的外端上。在这种实施方案中，轮毂沿着曲轴设置在大齿轮之间。可提供由滚子轴承或润滑衬垫机械地支撑在所述泥浆泵中的小齿轮轴(或者分离的对轴)。本发明还公开了另外的系统、设备和方法。
