Problems solved by technology

[0003] The planetary gear reduction device has been widely used in electric mine dump wheels due to its advantages of small size, light weight, high load capacity, large transmission ratio range and high efficiency, as well as the independent characteristics of power splitting and multi-tooth meshing. In the side deceleration device, the wheel side deceleration device of the electric wheel mine dump truck not only undertakes the function of transmitting speed and torque, but also plays the function of connection and load bearing. Due to the large tonnage and harsh working environment of the electric wheel mine dump truck, the The structural form of the wheel-side reduction device is an important facto

Abstract

The invention discloses a hub reduction device for a mining dump truck with electric wheels and belongs to the technical field of hub reduction of engineering machinery vehicles. The hub reduction device comprises a main body, a driving motor, a secondary planet carrier, a retainer ring I, a sealing ring, a bearing I, a hub, a secondary planet shaft, a bearing II, a secondary planet wheel, a secondary annular gear, a spacing ring, an axle baffle I, a retainer ring II, a primary planet wheel shaft, an end cover, a primary annular gear, a primary planet wheel, a bearing III, an axle baffle II, a respirator, an outer end cover, a primary planet carrier, a primary sun wheel, a bearing IV, a half shaft, a connecting shaft, a half shaft flange and a motor shaft flange. The hub reduction device has the beneficial effects that construction is reasonable, mechanism of the whole mining dump truck is reduced, use ratio of space is high, safety and reliability are supplied, service life is prolonged, power consumption of the whole mining dump truck is reduced and use cost is lowered.

Description

technical field [0001] The invention relates to a wheel-side deceleration device, in particular to a wheel-side deceleration device of an electric wheel mine dump truck, and belongs to the technical field of wheel-side deceleration of engineering machinery vehicles. Background technique [0002] At present, the increasing size of mining dump trucks has made electric wheel mining dump trucks widely used. In the prior art, electric wheel mining dump trucks use electric transmission systems as the power of the vehicles, and lack traditional machinery. Therefore, it is necessary to set up a wheel-side reduction device. Therefore, the wheel-side reducer not only undertakes the function of transmitting speed and torque, but also plays the role of connection and load-carrying. [0003] The planetary gear reduction device has been widely used in electric mine dump wheels due to its advantages of small size, light weight, high load capacity, large transmission ratio range and high ef...
