Rossi UK to launch new series planetary reducers to UK market at Hillhead 2012

Rossi UK a division of Habasit Rossi Ltd will formally introduce the newest range of Planetary gear reducers and geared motors at the upcoming Hillhead exhibition says Cliftin Bower the General Manager of Rossi division." This follows closely on the Global launch due to take place in Hanover in April this year " The launch is the final step in the process as the company is investing in tooling and stock which will enable the UK operation to assemble from modular components and significantly improve delivery for its growing customer base. The company will also exhibit a comprehensive product range including its G05, A04 geared motors as well as servo precision geared motors.
The main design criteria for the new planetary range is to increased performance compared with the previous EP02 series of Rossi Planetary units, using where possible the same dimensions but enhancing the commercial advantages for the end user. This was made possible due to enhanced calculation of every mechanical component, specifying high quality materials and state of the art machining through every process, The design took into account the latest available lubricants, which could reduce friction and extend service life of the gear reducer.
The new planetary range was initially launched in 2010. The first phase included 9 sizes with a maximum torque capacity of 21,200Nm and now the range will be extended by a further 14 sizes with a torque capacity of 250,000Nm. The Italian parent Rossi SPA, is currently designing the range to be extended even further
The range was designed, such that the increase in performance between one size to the next is 40%, compared to the 60% performance found in the current EP02 Rossi range. This means that the new range is generally 1.18 times closer to adjacent sizes when compared to the main competitors. This allows the product to placed between current sizes on the market which we believe gives us the ability to select a product that is more cost effective without compromising performance
One of the design changes of the high speed gear trains, is the use of full complement roller bearings without an internal race and runs directly on the shaft, instead of the traditional needle roller bearing. This was done to increase dynamic load capacity. The critical factor here was the "roughness" on the roller race way on both the shaft and planetary gear. Due to the state of the art machining process this specification is limited to a Ra = 0,2 ÷ 0,3. Generally the competitors would use a RA value of 0,4.
"The adoption of roller bearings instead of needle roller bearings increases the dynamic load capacity, but reduces the static load capacity; however, this does not represent any
problem as the static breakage limit of gear reducer is never represented by the bearing." Says Lionel Gibson the Technical manger of Rossi UK. "The added advantage of reducing friction and using this bearing configuration is that the range is more efficient and thermal powers are increased. This has traditionally been a problem limiting the use of planetary reducers in many more applications. The Oil flow passages are also widened allowing for greater oil capacity and increased flow"
The output design takes into account all the relevant and current configurations such as cylindrical shaft with foot or flange design as well as hollow shaft shrink disc, keyed or splined shafts. Rossi UK will have a comprehensive range in stock and will be able to meet most requirements from stock. Should the reducer require a component that is not in stock, the group has access to stock globally such as Italy, Spain, America and even as far a field as Australia.
Rossi geared products have a strong reputation for excellent quality and the group has recognised that customers continue to demand greater value for their money. As such the focus is to ensure a greater competitive position is achieved through the improvement of the Operational structure as well as the development of a local Technical department in order to provide complete technically designed solution tailored specifically to each customer's application within the time constraints set by our customers.
Rossi has established a strong track record in providing tailored technical solutions for a wide range of applications, such as Material Handling Conveyors, Mixers & Agitators, Quarrying, Mobile Aggregate Machine, and Recycling centres and believes that the company is well placed to develop the market through investment and focus in key areas.
"Further investment will continue through 2012 and beyond with the development of customer portals such as the "ROSSI FOR YOU" and "ROSSI SOLUTIONS" portal and the launch of a new simplified and updated website" Says Cliftin Bower . "These tools will enable our customer to review the status of their orders in real time along with 3-D drawing download capability, order history and many more tailored functions. The launch of this portal is expected in Q3 of this year."
Rossi UK has an inventory value in excess of £1.0 million comprised of the Company's comprehensive range of electric motors, brake motors, gear reducers and gear motors. Our stock profile includes more than 10,000 assembled gear units and electric motors allowing for immediate dispatch throughout the UK and Ireland. Habasit Rossi can offer gear units with a torque capacity of 22,000Nm from stock in the UK and gear units up to 800,000Nm from stock held in Italy.
The Rossi UK subsidiary was established in the Midlands nearly 25 years ago and has set ambitious growth objectives for the future. This growth objective has been fully supported through Rossi SPA, Italy where over the last 5 years the company has invested Euro 75 million in new machinery, production facilities and staff to meet the growth trends as the group expands its global footprint.
The Hillhead Exhibition will allow the company to showcase some innovating designs and will be in the main Pavilion (P71) For further information on the new range of Planetary reducers please visit our stand.
