Abstract
The utility model relates to an automobile accessory, in particular to a Terex mining automobile wheel-side speed reducer. The Terex mining automobile wheel-side speed reducer is provided with a planetary frame and a half axle; an axle is arranged on the planetary frame; a planetary gear is arranged on the axle; one side of the planetary gear is positioned on the axle and provided with a clamping sheet; and a sun wheel is arranged on the half axle and meshed with the planetary gear. The Terex mining automobile wheel-side speed reducer is characterized in that: two abreast cylindrical roller bearings are arranged between the planetary gear and the axle at a certain distance. According to the Terex mining automobile wheel-side speed reducer, the problems of frequent faults and the like caused by overload on the bearings of the conventional mining automobile wheel-side speed reducer are solved, so that the bearing capacity of the bearings is improved, the manufacturing process for corresponding accessories is simplified, and the number of faults of a vehicle is reduced, and the consumptions of accessories and fuels are reduced; and the utility model is particularly suitable for Terex 33-07 (NHLTR50) mining automobile wheel-side speed reducers.
Description
The (1) technical field: the utility model relates to auto parts machinery, especially a kind of special rex mine truck wheel reductor.
The (2) background technique: at present, special rex mine truck wheel reductor is referring to Fig. 1, and it has planet carrier and semiaxis; Axle is housed on the planet carrier, on the axle planetary pinion is housed, between planetary pinion and the axle two needle bearings that are arranged side by side are installed; Planetary endoporus is the outer bowl of needle bearing, and axle is interior bowl, and planetary pinion one side is positioned at card also is housed on the axle; Sun gear is housed on the semiaxis, and sun gear and planetary pinion are meshing with each other, and power is passed to sun gear by semiaxis.As everyone knows, the needle bearing limit speed is than low, and bearing load carrying capacity is poor, in addition; The outer bowl corresponding gear endoporus of bearing, and bore hardness is limited, easy abrasion under the heavy load condition; Because domestic mine truck often overloads, road conditions are relatively poor, make bearing often work overloadingly; Therefore vehicle trouble is many, and bus dispatching rate is low, and cost is high.
The (3) summary of the invention: the purpose of the utility model is exactly will solve traditional mine truck wheel reductor to carry problems such as the accessory frequent change cause and respective accessory manufacturing process complicacy owing to the bearing overburdening, and a kind of special rex mine truck wheel reductor is provided.
The concrete scheme of the utility model is: improve to traditional special rex mine truck wheel reductor, it has planet carrier and semiaxis, and axle is housed on the planet carrier; On the axle planetary pinion is housed; Planetary pinion one side is positioned at card also is housed on the axle, and sun gear is housed on the semiaxis, and sun gear and planetary pinion are meshing with each other; It is characterized in that: between said planetary pinion and the axle two roller bearings that are arranged side by side are installed, the two roller bearings layout that keeps at a certain distance away.
The exterior edge face of two roller bearings described in the utility model is concordant with planetary right ends face respectively.
Have two draw-in grooves that are arranged side by side and keep at a certain distance away described in the utility model in the planetary bearing hole, the jump ring that blocks two roller bearing interior edge faces all is housed in the draw-in groove.
The spacer ring that blocks two roller bearing interior edge faces is housed in the planetary bearing hole described in the utility model.
Have the seam that blocks two roller bearing interior edge faces described in the utility model in the planetary bearing hole.
The utility model is improved to roller bearing with needle bearing, has increased the bearing capacity of bearing greatly, and the manufacturing to gear and axle simultaneously requires to reduce greatly; Simplified the manufacturing process of gear with axle; Prolong the working life of mine truck wheel reductor, vehicle trouble minimizing, bus dispatching rate are increased, thereby reduced the consumption of accessory and oil plant; And improve working strength of workers, be widely used in special rex 33-07 (NHLTR50) mine truck wheel reductor.
