STÖBER Antriebstechnik GmbH + Co. KG takes on a leading role in the CO2-neutral use of eco-gas. The company has a balanced carbon footprint thanks to the supply from SWP.
In addition to green electricity, STOBER has also been using climate-neutral eco-gas from SWP as the energy resource in its regional operational facilities since the beginning of this year. The globally active company, headquartered in Pforzheim, was recently awarded an eco-gas certificate for this measure.
STOBER’s CEO Patrick Stöber was visibly proud when he spoke about the fundamental decision to use eco-gas as a form of energy. “Our company stands for high quality in all areas. We place the greatest importance on outstanding products, satisfied employees and energy use that conserves resources as much as possible.” Stöber asserts that this award as well as the others that the company has received in recent years are not just public advertising for the company, however. “They also lead to greater motivation among the staff because the employees each have reason to be proud of their company.”
This special certificate was presented by the CEO of Stadtwerke Pforzheim, Herbert Marquard, himself “as a matter of course.” Marquard emphasized, “We are happy that STOBER is the first company in our region to receive this certificate for its commitment. We are also very proud to have such a loyal customer and reliable partner at our side.”
How is the certification carried out?
Climate-neutral eco-gas – how does that work?
In collaboration with sustainability agency KlimaInvest Green Concepts from Hamburg, CO2 emissions produced by heating systems and production processes during natural gas production are calculated. These CO2 emissions are effectively offset for the environment by investing in certified climate protection projects. As a result, the eco-gas used is 100% climate-neutral.
How is CO2 neutralization guaranteed?
By purchasing climate-neutral eco-gas, the purchaser makes a contribution to climate protection. This supports climate protection projects that satisfy the highest international standards. Compliance with these standards and logging of CO2 emissions from the supplied quantities of eco-gas are annually checked and certified by climate protection partner KlimaInvest Green Concepts and additional, independent testers such as TÜV Nord.
Which quality criteria satisfy the supported climate protection projects?
Sustainability agency KlimaInvest Green Concepts collaborates with independent testing organizations such as TÜV to check and certify that the supported projects are sustainable and ecologically sensible. The projects correspond to one of the world’s most demanding standards, the Verified Carbon Standard (www.v-c-s.org), which follows the criteria catalog of the UNFCCC (United Nations Framework Convention on Climate Change). Furthermore, this project standard guarantees that no climate protection projects are supported that were implemented without certified contribution to climate protection. This additional requirement is documented and certified for every climate protection project that KlimaInvest supports.
Dişsan DKP Series Planetary Gear Units for Mixers
Planetary gear units enable high power capacities in compact sizes. DKP series planetary gear units are specially designed for twin shaft concrete mixers. They are available in sizes suitable for 1 m3, 2 m3, 3 m3 and 5 m3 mixers.
DKP series gear units have a special input flange that enables to connect the gearbox with belt pulley as well as to connect two gearboxes with cardan shaft.
Thanks to their rigid structure, they are suitable to operate safely even in harshest conditions. Housing material is GGG40 cast iron. Gears are produced from high quality, case hardened steel. Heat treatment process is applied to obtain 58-60 HRC surface hardness. The gears are precision ground to ensure a quiet and low vibration operation. Special oil seal options are available.

Main causes of gearboxes failures
In a world of optimization and digitization where factories are trying to reduce costs and downtime, the identification of basic gearbox failures can help you to save money and precious time so let the repair shop and service team become a key part of your optimization process.
With almost 50 years of years in the design, development, production and servicing of gearboxes and power transmission solutions, I-MAK’s experience has produced over a million possible configuration of its products implemented in thousands of applications. As a result, and while closely communicating with customers and end users we identified 3 main reasons for gearboxes failures.
1. Alignment of the gearbox on the application
This first cause of gearbox failure is purely mechanical, gears being designed to work in a certain configuration and backlash settings for each gear tooth, that when misaligned can cause a concentration of loads on a part of the gear, housing, bearings or other weaker part of the gearbox and induce premature failure. The identification of misalignment can be done during the maintenance period throughout the lifetime of the gearbox. Before failure, the healthier way to process is to ensure the right mounting of the gearbox during the installation in a new application or after the servicing of some of the machine’s components. We also advice a regular control of the gearbox alignment, our service team is controls this alignment during our regular visits with end users that signed an I-MAK Service plus agreement, securing an early identification or future failures.
2. Lubrication of the gearbox
Most of I-MAK’s gearboxes are supplied with high quality lubricant oil adapted to the type of application, environment and mounting configuration. As the manufacturer, IMAK calculates the right quantity and defines the right type of oil to ensure an ideal lubrication for both gears and bearings. The bath and splash lubrication configurations allow the right spread of oil in the gearbox, allowing the oil to create a thin film on the gears. This thin layer of oil prevents a metal to metal contact between the gears during their engagement. During the gearbox lifetime the oil quantity and quality can change depending on the applications and regular service intervals. Sealed and protected from external pollutants, that can affect the oil quality is a good method to ensure the health of the gearbox, a yearly oil change is recomended to allow for optimal lubrication. During the oil drain a quick analyse of the oil quantity, colour, presence of external elements, can give key indicator of the gearbox health and conditions. Gearboxes working in harsh condition can lose significant quantity of oil during their lifetime, causing a lack of lubrication of the primary gears and irreversible damages.
3. Overload and operating mistakes
Often exposed to harsh working condition, the gearboxes also suffer from overload and operating mistakes. Gearboxes are initially supplied with the right configuration and service factor to offer optimal working and enhanced performance. Yet the working conditions at the end user facility can differ from day to day and sometimes grow to extreme for the gearboxes, in facilities like; water treatment plants, bulk material producer and recycling companies. These applications are often the ones imposing the hardest working conditions to the gearboxes. Exposed to external conditions these operators are regularly forced to stop their operation in emergency due to rain, electrical outages, feeder overloads etc. During these emergency stop events, heavy loads are applied to the output shafts, torque arms and backstop devices. Fully loaded a conveyor, mixer or shredder is demanding an extra effort to the geared motors until it gets to the requested operating speed. Soft start devices and adapted automation can reduce the overload and mitigate the efforts made by the gearboxes. Unfortunately, it is hard to identity a damaged gearbox in such noisy environment, at the same time the gearbox rarely shows noise or vibration difference until it is too late. At this stage the operating temperature of the gearbox remain a good factor to identify potential failures that sometimes take years to appear.
Although gearbox failures cause are not limited to these 3 causes, applying these basic advice could help you to save thousands of dollars and precious hours. We also invite you to consult our I-MAK Online service team, a unique online support service available in 5 different languages 24h/7.
