JS Series Reduction Gears is the main product of our company. It gathered the driving technologies, especially the rich designing and manufacturing experiences of large-scale, high precision, hardened surface and heavy-duty gear driving equipments made by the company.

At the same time, it also adopted the technological advantages of the Reduction Gears for Mill manufactured by foreign countries, thus a new type of large powered central driven product is developed.

JS Series Reduction Gears was evaluated by National construction Material Industry Standardization Technology Commission as the industrial Standard in 2001. Standard No. is JC/T878.1-2001.

The Main Reduction Gears is a cylindrical gear-driving device with its parallel shaft being involutes. Since a layout of power shunting and synchronous transmission gear system, which can adjust the load of each gear, is adopted, it possesses the features of compact structure, small size and lightweight.

The High-grade alloy case-hardened steel is used for manufacturing all driving gears of the reducer. The surface of each gear has been cemented, hardened and ground, so it has high precision and loading capacity.

The Thin-wall sliding bearings and eccentric sliding bearings with multi-degree of freedom are used, thus its installation and adjustment can be easily done, and the accuracy of gear engagement be guaranteed.

The housing of reduction gear is welded and its appearance is simple and beautiful.

Its main parameters have been obtained by means of optimized design. In addition, this Reduction Gears Device also bears the features of.
. Standardization in component structure,
. Seriating in size,
. Packages are all in modules, and
. Compatibility and high degree of exchange ability for all components

The major auxiliary system-low speed driving gear has been designed small in size light in weight and in the way of high degree in standardization. It can meet many demands about ahead driving and astern driving.

The diluted oil lubricating station is equipped with 2 set of gear pumps which can be reserved each other to ensure the reliability for lubricating system. In order to ensure the safety for equipments, good lubrication oil pressure, and temperature monitoring and alarming system are used, lubrication oil heating system can meet the operation demands in the high cold lands.

12 channel transverse thermal resistors and advanced changeover circuit are used for multi-path temperature periodic indication. Bearings number of main reduction gear and temperature value is displayed by high brightness LED digital indicator. The computer's controlling system is provided with 4-20mA standard signals and the alarming system's comparator is provided with located switching signal.

With the features of advanced performance, high reliability, JS Series Reduction Gears for Central Driven Mill can be widely used for the raw cement mills in the fields of building materials, metallurgy as well as sugar industry, etc.

Its success stands for the company's capacity of independently designing and manufacturing heavy-duty Cement Mill Reducer ranging from 4000kW to 4500kW.
