Abstract

The invention discloses a hub reduction gear for an off-highway mining dump truck. The hub reduction gear comprises a driving motor, a frame, a driving ring, an input end sealing assembly, an output end sealing assembly, a hub, tapered roller bearings, a connecting flange, a torque tube, a duplex inner gear ring, a primary planetary carrier, a secondary planetary carrier, an end cover, a friction plate combination, a secondary sun gear, a limiting device and a primary sun gear; the driving ring penetrates through the input end sealing assembly that is fixedly connected with the frame through a bolt; the output end sealing assembly is mounted between the hub and the frame; the hub is rotatably supported on the frame through a pair of tapered roller bearings; the connecting flange abuts against one tapered roller bearing; the end cover is connected with the secondary planetary carrier through a bolt; the friction plate combination is mounted between an end face of the secondary sun gear and an end face of an inner cavity of the end cover; and the limiting device is located between corresponding end faces of the primary sun gear and the secondary sun gear. The hub reduction gear is simple in structure, sufficient in lubrication and high in service life.

Description

technical field [0001] The invention relates to a non-highway mining dump truck, in particular to a mining electric transmission dump wheel side reducer. Background technique [0002] After decades of development, mining dump trucks have grown from miniaturization to large-scale mining vehicles. For large-tonnage mining vehicles, the traditional mechanical transmission can no longer meet the requirements of high speed, high torque and high transmission efficiency. Electric transmission is used instead. The wheel reducer of planetary transmission is widely used in the electric transmission of large mining vehicles. At present, the wheel reducers used in the domestic market generally use two-stage planetary differential gear trains (one-stage differential gear train and one-stage quasi-planetary gear train). Low life, inconvenient maintenance, etc. Contents of the invention [0003] The invention aims to provide a wheel-side speed reduction device with simple structure, su...
