Application example SPN worn gear for weaving mashine

Gear optimization is our daily business, and yet for every project we make it our business to meet the requirements of the product in a customer-specific, reliable and precise manner.

During development, special attention must be paid to the given gear connections as well as to the function and required performance data from the specifications and performance specifications. In the textile machinery industry, for example, it is very important that proven and sometimes very sensitive processes must not be changed.

A well-known worldwide leading textile machine manufacturer, with over 130 years of experience, develops and builds, among other things, high-end weaving machines. These machines are used to manufacture products such as safety belts for vehicles, safety-relevant load belts, high-quality textile labels, shock absorber belts or compression bandages for the medical sector.
Due to competition from Europe and Asia, textile machinery manufacturers are also under increasing price pressure. An external price study was therefore carried out with the result that all components of the transmission were re-ordered. Initially, only the gear components were requested with the aim of minimizing the sales price of his complete system. These bought-in production parts as well as the standard parts were to be completed to a worm gear unit in the customer's own assembly department.

After checking the requested production drawings in our engineering and project management departments, it was clear to us that we could minimize the components without changing the design and center distance by making a design change. After the adjustments of the existing components were not sufficient to achieve the desired target price, our development and project management team realized that this was only feasible if the center distance and thus the installation space was reduced. This measure enabled us to save material and processing costs for the individual components and to achieve the target price. Here the challenge for the new development was to define an optimum bearing arrangement taking into account the new design for the smaller installation space. According to the specifications, the existing central lubrication system of the machine had to be used for the lubrication, since the lubricant is to be procured worldwide within a short time and changed on site. The implementation was only possible through a very open and close cooperation. A strength of SPN.

• Reduction of the axis distance
• Weight reduction
• Volume reduction
• Compact installation space 
• Reduction of production and standard parts
     
     

A compact, powerful and maintenance-free worn gear designed for central lubrication.

The target product of our end customer, a technically and economically optimized worm gear unit, was thus perfectly, precisely and customized in all required points.

SPN Schwaben Präzision supports its customers in after-sales after the project has been completed by supplying spare parts and offers a comprehensive service such as maintenance and repair.

In addition to the very short-term deliveries, we were able to convince our customers above all by not doing the assembly themselves, but by leaving it to us - the gear specialist SPN Schwaben Präzision.
