The slewing drive is a gearbox that can safely hold radial and axial
loads, as well as
transmit a torque for rotating. The rotation can be in a single
axis, or in multiple
axes together.
Slewing drives are made by manufacturing gearing, bearings, seals, housing, motor and other auxiliary components and assembling them into
a finished gearbox.
Slewing drives function with standard worm
technology, in which the worm on the horizontal shaft acts as the driver for
the gear. The rotation of the horizontal screw turns a gear about an axis
perpendicular to the screw axis. This combination reduces the speed of the
driven member and also multiplies its torque; increasing it proportionally as
the speed decreases.[2] The
speed ratio of shafts depends upon the relation of the number of threads on the worm to the number of
teeth in the worm wheel or gear.[3]
As technology has improved, more slewing drives are using
hourglass worm technology, in which the worm is shaped to engage more teeth in
the gear.[4] This
increased tooth engagement results in greater strength, efficiency and
durability.

Recently, Huawei and ORACLE formally signed the Memorandum of Understanding for the Eco-Partnership of the Power IoT, and will continue to collaborate on Huawei's AMI solution with Oracle's public utilities MDM, SGG and other related products for joint program development, marketing and market expansion.
According to the memorandum, the two parties will continue to collaborate based on customer needs, make full use of Huawei's leading technologies in information and communication products and solutions, and use Oracle's solutions for R&D, implementation, and consultation of solutions for global public utilities such as water, electricity and gas. Service outsourcing capabilities, providing end-to-end AMI solutions to customers in collaboration with their respective resources, helping power companies improve customer experience and improve power quality, achieve energy conservation and emission reductions, improve corporate operational efficiency, and reduce operating costs.
Previously, Oracle and Huawei successfully completed interconnection and interoperability testing of the Huawei AMI Solution Front-End System (HES) with Oracle MDM and SGG. Huawei's fully-connected power grid AMI solution and Oracle MDM system are based on standard IT technology, using an open architecture for interoperability, and Oracle MDM achieves basic functions such as remote metering, data acquisition, and event acquisition through the HUAWEI northbound interface. In this way, the AMI solution includes intelligent meter reading, remote control, power steal analysis, and power supply quality analysis. The two sides based on successful interoperability testing and technical discussions to establish an ecological partnership and help build a global smart grid.
Tunisia Utilities Selects Huawei Tunisia Power & Gas Selects Huawei to Develop an Integrated Smart Measurement Solution with a Local Electric Equipment Manufacturer.
This is the first implementation of Advanced Metering Infrastructure (AMI) in Tunisia. This deployment will ensure Tunisian Utility Company (STEG) optimizes its revenue process through accurate billing and reduces the number of electricity thefts due to instrument modifications.
It is expected that users of the utility company will be able to use energy more efficiently and obtain real-time data.
Smart metering technology can also help STEG manage its grid network in real time, reduce power outages, improve customer experience, and promote the development of STEG and the introduction of new business models such as demand response and energy efficiency projects.
Huawei has confirmed that it has signed an agreement with SIAME Industrial Co., Ltd. Both parties jointly provide smart meters for Tunisian Electricity and Gas Company (STEG).
The integrated measurement solution also includes instrument data management software and technology to enable connectivity between smart meters and utility companies. The technology will gradually improve and help many utility companies in Africa and the Middle East gain the benefits of smart grid technology.
Africa's metering market It is reported that by 2026, utility companies in sub-Saharan Africa will invest 8 billion U.S. dollars in the instrumentation industry.
Nearly a third of the electricity produced in Africa has never been charged to customers. This means that utility companies do not have enough income to maintain their networks, nor can they finance the necessary expansion. Therefore, utility companies in sub-Saharan Africa must upgrade their metering infrastructure as soon as possible.
Although Africa is the fastest growing metrology market in the world and is the leader in prepaid metering, the market share of prepaid meters is just over 40%.
However, in the near future, utility companies in African countries including South Africa, Nigeria and Ghana will begin to increase the deployment of advanced metering infrastructure. It is estimated that there will also be significant growth in the commercial and metrological market in the next decade.
