Franz Morat unveils innovative system that comfortably rotates and turns bedridden patients

by Leave a Comment

For bedridden individuals, everything revolves around the correct resting position in the bed. The position must be adjusted to match each individual patient and their physical condition.

This means the patient’s position in the bed must be changed regularly to take pressure off of areas of the patient’s body and to prevent pressure sores. The goal is to make life in bed as pleasant as possible for the person in need of care.

Turning and repositioning bedridden individuals is a physically challenging procedure for caregiving staff. It is usually performed multiple times per day by a team of two or three caregivers and it requires a lot of time.

More flexible gear machining for industrial robots

by Leave a Comment

Today’s industrial robots must fit into smaller spaces, so as much “manufacturing real estate” as possible is dedicated to production. This places pressure on manufacturers to machine smaller, tighter components for these machines. Here, Harish Maniyoor, global product manager for automotive at the machine tooling specialist Sandvik Coromant explains why power skiving is the answer.

The overall number of industrial robots operating in factories worldwide grew to 2.7 million in 2019, according to the 2020 World Robotics Report by the International Federation of Robotics. 

This was a 12 percent increase from 2018 and a historic high. Robots factor into a range of industries, from automotive and aerospace to the food industry and pharmaceuticals – yet all of these sectors have common requirements.

Not only must these robots be smaller, but also lighter with reduced inertia and able to perform more exact movements with optimal speed and efficiency. The challenge is on for manufacturers to machine smaller and more precisely engineered-components – like internal gear reducers – with more flexible designs.

Spinea_DS

Spinea has launched its new DS 095 DriveSpin servo actuator motor for precision control.

Recently announced by Spinea and available in the UK from Heason Technology, the DriveSpin DS 095 series integrates the industry leading TwinSpin high-load capacity trochoidal gear unit and a powerful AC servomotor with servo feedback for a cutting-edge rotary actuator solution for precision motion applications.

The inline (non-hollowshaft) design of the DS 095 fulfils the gap between the DS 70 and DS 100 models to provide a rated torque of up to 85 Nm and maximum lost motion and hysteresis values of less than one arc-min.  [Read more…] about Spinea launches new servo actuator for precision motion

Yaskawa introduces gear motor capabilities for its full Sigma-7 servo line

by

The Drives & Motion Division of Yaskawa America has released what it says is “a full line of gear motors” based on its Sigma-7 servo motors.

The new line brings “precise Yaskawa servo motion to a wider variety of automation applications than ever before, especially to uses which require high torque at low
output speeds”, says the company.

A new set of gearheads have been designed to pair precisely with every servo motor in the full Sigma-7 range, creating complete gear motor solutions rated from a low of 50W to as high as 7.5 kW.  [Read more…] about Yaskawa introduces gear motor capabilities for its full Sigma-7 servo line

Nord Drivesystems shows modular industrial gear units in additional sizes

Nord Drivesystems has presented two new gearboxes for nominal torques of 15 and 20 kNm.

The company says its new industrial gear units greatly increase the possibilities for configuring application-specific drives in the load range up to 20,000 Nm, for example with a dual gear setup and swing base.

With these latest additions to the line-up, the series now comprises 11 gearbox sizes that deliver output torques up to 250 kNm.  [Read more…] about Nord Drivesystems shows modular industrial gear units in additional sizes

Redesigning the gear: A closer look at Harmonic Drive’s new WavePlus technology

Graham Mackrell, managing director of precision gearing expert Harmonic Drive UK, explains WavePlus technology, an innovative development in strain wave gearing

Sometimes, you only need one small innovation to make something revolutionary.

Sliced bread, for example, simply took a stroke of inspiration for Otto Rohwedder to combine automatic bread wrapping equipment with cutting functionality.

The strain wave gear has been the pinnacle of precision gearing since the technology was first developed in 1957 by renowned inventor and founder of Harmonic Drive, Walton Musser.

Consisting of just three crucial components – the wave generator, flexspline and the circular spline – and ensuring zero backlash as well as a high gear reduction ratio, strain wave gears have long been the standard for critical applications.  [Read more…] about Redesigning the gear: A closer look at Harmonic Drive’s new WavePlus technology
