Customized gearbox solutions for a wide range of applications

SPS – Smart Production Solutions is the industry highlight of the automation sector and, with its unique concept, covers the entire spectrum of smart and digital automation – from simple sensors to intelligent complete solutions.

With the latest technology and a pronounced innovative strength, SPN is in a position to set decisive impulses for the future: in terms of more quality, more flexibility and, above all, more productivity. SPN Schwaben Präzision is the technology-independent drive designer with its own high-performance production. SPN-Drive Monitoring makes digital gearbox monitoring possible and offers many advantages.

Short cycle times, robust technology, wear-free surfaces and compact designs have always been relevant for automation solutions. Application areas in difficult environmental conditions such as clean room requirements or corrosion and acid resistance are taken into account in the design of SPN's customized gearboxes.

With SPN-Drive Monitoring and specially developed sensors, the company is focusing on innovative and future-oriented trends in the digitalization of customer-specific drive solutions.
At this year's SPS, the company will be showcasing different and special application examples with the specially developed drive and gearbox solutions.

An SPN spur gear and planetary gearbox combination supports earth drilling work

Together with its customer, SPN has developed a four-stage gearbox for a drill driver application for earthworks. It consists of a drive spur gear stage and a three-stage planetary gearbox. The gearbox ensures effective transmission of the motor power to the tool that drives in the earth anchors. This enables the tool to work in hard ground or where there is resistance from roots or stones without overloading the motor. Efficient power transmission and optimum speed adjustment allow the device to work more energy-efficiently. A compact design increases mobility and flexibility on the construction site and facilitates access to hard-to-reach areas.

Technical data of the drill driver gearbox:

• 1ph IPM or PMAC motor
• Rotational speed ~ 6.5 rpm
• Total gear ratio i = approx. 1160:1
• Backlash =10'
• Output torque T2 = 5,000 Nm
• Suitable for mounting a high-efficiency brushless digital IPM motor with pressed-in pinion for driving the gear unit
• Integrated motor controller, which always supplies the motor with the optimum voltage and frequency. This allows the machine to run at full torque over a wide load range without the speed dropping.
• Built-in communication module for Bluetooth or WiFi interface.
• The functions are supplemented by remote logging of projects and torque values. Fleet management, machine status and service/operation logs.

The switchable multi-stage SPN helical gearbox for precise maintenance work

The end product is a versatile portable drill. The use of state-of-the-art servo motors and a user-optimized control interface enable simple and safe machining.

Different jobs such as drilling or facing require different speeds and torques. A gearbox enables precise adjustment of these parameters to meet the specific requirements of each task. . This allows you to switch between drilling with high speeds but lower torque and for face turning at low speed at higher torque. The multi-stage gearbox allows you to switch between different ratios. This is particularly useful when different jobs are to be carried out on one machine.

Advantages:

• Adjustment of speed and torque
• Improved power efficiency
• Versatility through gear changes
• Compact design
• Increased control and precision

Technical data of the gearbox:

• Max. drive speed: 3.600 min^-1
• Rated output torque: T1 = 54 Nm / T2 =165 Nm
• Gear ratio: i1 = 11,999 / i2 = 36,756
• Weight with motor: 22,3 kg
• Service life approx: 9.500 hours

Keeping track with SPN-Drive Monitoring

A central exhibit at the SPS is a gearbox solution including a contactless torque sensor.

Details:

• Slim and compact sensor: space-saving design, ideal for tight installation conditions
• Attractive price ensures suitability for series use (factor 5-10 cheaper compared to conventional torque measurement shafts)
• Uninterrupted operation: measures the torque without interfering with the shaft being measured
• Visitors can playfully pull the lever and thus directly influence the torque
• Torque is displayed as a graph on a monitor in real time
• Maintenance-free operation thanks to non-contact technology

With this exhibit, SPN will show visitors at SPS an innovative solution for precise, cost-efficient torque monitoring in gearboxes with an interactive, understandable and clear model that can be tried out directly on site.

In addition, a monitored drive train in suitcase format will be on site, which has an extremely compact design of the torque sensor for shafts with a ø15mm, enables precise torque detection even with rotating shafts and innovative, wireless sensor nodes with minimal installation effort and no need for physical connection cables. The Sonsor reliably measures temperatures and gearbox vibrations. The sensor data is sent directly and wirelessly to the cloud. The sensor nodes work autonomously and do not require permanent maintenance. They are energy-saving and environmentally friendly (2 years runtime and then rechargeable)

Ongoing analysis of the measured values enables real-time data processing with direct feedback on system performance Various analysis algorithms provide insight into the health of the gearbox. Users receive immediate evaluation and diagnostics on system integrity via a website provided by SPN, accessible at any time and from anywhere

This means that potential faults in the process or drive can be identified at an early stage.

The SPN Drive Monitoring concept thus combines the expertise of developing customer-specific gearboxes, monitoring field tests and evaluating them, as well as series delivery in a state-of-the-art production facility under one roof. The digital support and evaluation of validation in the field leads to faster and more comprehensive information under real conditions and thus increases the series durability of the drives and enables a development process that is as resource-efficient as possible. The SPN Drive Monitoring System can also be used to analyze the real load data in a drivetrain before a transmission is developed. With the real load data, the size of the gearbox can be matched even more precisely to the application, resulting in cost and resource savings.
