One end connected with a flange is connected with the inner gear ring through the bolt and a spline, and the other end is connected with the back shaft through the bolt.
Description
Technical field
Large-scale heavy duty mining electric wheel dump truck wheel side speed reducer of the present invention relates to a kind of large-scale mine electric wheel dump truck, particularly 290 tons of other mine trucks of load-carrying higher level for mine transportation use.
Background technique
Be used for other mining heavy load truck of 290 tons of higher levels of transportation on glory-hole, the wheel side speed reducer that drives use on it is arranged on the tire center portion, size is limited by tire, volume is little, carrying is large, structure is special, used whole of present domestic high capacity car are import, and are expensive, the maintenance cost is high.For existing problem in above-mentioned prior art, a kind of novel large-scale heavy duty mining electric wheel of research and design dump truck wheel side speed reducer, in prior art, existing problem is very necessary thereby overcome.
Summary of the invention
In view of existing problem in above-mentioned prior art, the objective of the invention is a kind of novel large-scale heavy duty mining electric wheel of research and design dump truck wheel side speed reducer.Thereby exist in the solution prior art: 1, speed reducer is arranged on the tire center portion, and size is limited by tire, and volume is little, carrying is large, structure is special, maintenance difficult; 2, used whole of domestic high capacity car are import, expensive, maintenance high in cost of production problem.
Technical solution of the present invention is achieved in that
Large-scale heavy duty mining electric wheel dump truck wheel side speed reducer of the present invention is comprised of level sun gear assembling at a high speed, the assembling of high speed level planet carrier, slow speed turbine stage sun gear, the assembling of slow speed turbine stage planet carrier, torque tube, ring gear, wheel hub and rear axle; It is characterized in that described high speed level sun gear assembling is connected with the slow speed turbine stage sun gear by the assembling of high speed level planet carrier, slow speed turbine stage sun gear and the assembling of slow speed turbine stage planet carrier are meshed by gear tooth; One end of torque tube is loaded on slow speed turbine stage planet carrier fit on by bolt, and the other end is connected with an end of wheel hub by bolt; The other end of wheel hub is connected with an end of wet brake by bolt; The other end of wet brake is connected with rear axle; One end of connecting flange is connected with ring gear by bolt and spline, and the other end is connected with rear axle by bolt.
Between the lid groove of the end of slow speed turbine stage sun gear of the present invention and slow speed turbine stage planet carrier fit on, wear washer A is housed.
High speed level sun gear fit on of the present invention is set with wear washer B and coordinates the location by the slow speed turbine stage sun gear.
Working procedure of the present invention is: the motor (not shown) drives level sun gear assembling at a high speed, driving at a high speed, thereby the assembling of level planet carrier drives the slow speed turbine stage sun gear, drive the assembling of slow speed turbine stage planet carrier by the slow speed turbine stage sun gear, drive the torque tube drive hub, realize rotation of wheel by wheel hub at last, wheel is contained on wheel hub, thereby drives travelling of car load.This wherein rear axle be non-rotary, connecting flange is linked together by bolt and its, then ring gear and connecting flange are in the same place by spline and Bolt Connection, is all both non-rotary.Wear washer A and sequence number 8 wear washer B are housed respectively in the both sides of slow speed turbine stage sun gear.The ring gear of two-stage is made of one, and has accomplished the principle of profile minimum.Rear axle and and wheel hub between braking when installing sequence number 11 wet brakes additional and being used for truck low speed.
Advantage of the present invention is apparent, is mainly manifested in:
The advantages such as 1, speed reducer of the present invention has compact structure, and volume is little, and carrying is large, and is easy to maintenance;
2, to have more service cycle long for wet brake of the present invention, the characteristics that reliability is high;
3, the present invention can change wear washer by the lid on the slow speed turbine stage planet carrier, adjusts axial clearance, maintains easily;
4, high speed level sun gear of the present invention is designed to assembling type, is convenient to processing, has reduced cost;
5, two-stage sun gear of the present invention and planet carrier are unsteady, make load distribution more even, carry greatlyr, and two-stage ring gear design all-in-one-piece makes volume less;
6, the invention solves high capacity car all needs import, and, maintenance cost high problem expensive with the motor bulk/volume buying.
The present invention has the advantages such as novel structure, processing is easy, cheap, the maintenance cost is low, safe and reliable, and it puts goods on the market in enormous quantities and will produce positive social benefit and significant economic benefit.
