the high quality products of Wuma variable gearbox

Wuma variable gearbox company always promotes the quality improvement endlessly and pursues the target that the customers are satisfied with.
mounted reducer company does upmost to meet or exceed the customers' expectation continually and manufactures the high quality products, gear unit, gear drive motor, power unit, brake power unit.

single stage gearbox ,the reliability of the quality

single stage gearbox with advanced technology, is a tower of strength in the field of technique renovation. On design, The reducer motor adopts the three-dimensioned modeling and the finite element analysis, which has shortened the research circle of products, gear unit, gear drive motor and guaranteed the reliability of the quality, can provide the transmission resolvable projects with special requirements for the customers much better.

Absolutely precise of the vertical gear reducer

Extremely dynamic
the vertical gear reducer make your robot more precise and more efficient
Absolutely precise
Precision gears give your welding robot the necessary “sensitivity” for exact processing
Exceptionally long life
Our low-wear gear solutions ensure a long life and smooth operation throughout the entire period of use
Compact design
Our engineers design Nabtesco gears to be very compact for easy integration in applications with limited space

Wuma mounted reducer clutches standard options

Wuma mounted reducer clutches are high capacity multiple-disc, hydraulically operated and cooled. All clutches have a soft clutch in system, ensuring shock free engagement of main engine.

The pinion shaft of the variable gearbox is made of forged alloyed steel. Other shafts are forged carbon steel. The output shaft has an integrated forged flange.

Hypoid gear reductions with a high degree of filtration

Abouts Hypoid gear reductions BEARINGS：
For gear sizes 38-56, plain bearings are used on the output shaft. Otherwise low friction bearings are used.
For gear size 62 and larger, plain bearings are used on both pinion and output shaft. The main thrust bearing is a tilting pad bearing and is rigidly supported. Otherwise low friction bearings are used.
Wuma power gearbox HYDRAULIC SYSTEM：
The hydraulic system is designed for lubrication, cooling and clutch control. All bearings are forced lubricated, the gear meshes have additional sprays for cooling and lubrication. The oil filters are designed for full flow and with a high degree of filtration.

Wuma vertical high torque gearbox to minimizing noise and vibration

GEAR WHEELS of the Wuma vertical high torque gearbox
The gear wheels have single helical teeth, precision ground with profile correction to
ensure both good load distribution and low noise operation. The material is alloyed gas carbonized steel. Double helical gear wheels are also available.
HOUSING of the vertical combined gearbox
The housing is made of cast iron or fabricated steel in order to make a rigid structure.
Extensive FEM calculations ensure limited deformation and low stress levels. Special attention has been paid to minimizing noise and vibration.

a high speed housing with Wuma vertical gear reducer

Wuma vertical gear reducer to provide a vertical right angle speed reducer including a box-like enclosure having a removable cover, the enclosure forming a lubricant reservoir and the cover provided with an integral lubricant distribution system for upper vertical shaft bearings supported within the cover.
The variable gearbox with lubricant circulating means mounted within a high speed housing removably attached to an end of the enclosure for ease of access to the circulating means.

Wuma gear reductions with a vertical output shaft

Wuma gear reductions to provide a vertical right angle speed reducer including a box-like enclosure adapted to alternately mount a vertical output shaft and one or more vertical intermediate shafts of double, triple, or cycloidal gear reducer gearing and in which one end of the enclosure is provided with a mounting opening to removably receive a mounting member which, together with a high speed housing removably attached to the end of the enclosure, supports appropriate horizontal input and intermediate shafts.
