SANY MG500/1202-WD Shearer

Advanced transmission system

Introduction of System-level Gear Micro-modification Technology。Fully consider the rocker arm housing、Influence of deformation of gear train。The service life of the gear is 20% longer than that of the traditional structures%Above。

The application range is wide

Can meet coal mine from 1.8 meters～4.2 meters、Inclination up to 40ºAnd other working conditions.。

The fuselage is low、Reliable walking，Adapt to that requirement of large dip mining work fact。

Equipped with standard type、Two machine surface heights of high type，Matchable 764、800、900 and other scraper conveyors。

The reliability is strong

Rocker arm adopts internal and external cooling combination mode，Effective control of working oil temperature 70℃Within，Fixed-point lubrication of planetary bearings。

The traction part is equipped with cooling water channel，Oil temperature is controlled at 40℃Within。

External self-cleaning technology，On-line filtration of gear oil，Ensure that the service life of the oil is twice that of the traditional way.。

And that maintainability is strong

The cutting motor adopts a short torque shaft structure.，Installation and replacement time reduced by more than half。

Cone shaft is used for articulation，Matching self-lubricating shaft sleeve without oil injection，And is convenient to maintain。

Drawer type structure shall be adopted for the installation of electrical parts.，Internal mass application harness design、Easy to maintain。

Airborne centralized refueling system，Remote control operation。The oil injection time of the whole rocker arm shall not exceed 20min。

High degree of automation

Take the special controller as the core，With intelligenceI/OModule，FormCANBus type control network。Comprehensive condition detection and monitoring。Automatic drum height adjustment、Temperature detection of bearing at high-speed end of rocker arm、Fuselage attitude detection、Automatic regulation of traction speed，Automatic protection of end derailment、The walking wheel has the functions of self-protection and the like。

Perfect protection function and higher intelligent degree provide constant power automatic control.、Gas overrun alarm、Danger value protection、Fault inquiry and diagnosis，As well as voice warning and other functions.。With coal and rock identification、Monitoring of complex working conditions、Automatic anti-drop and other functions。
