If you want to identify one trend in the field of shaft-hub-connections, this is it: The use of frictional shrink discs is gaining traction in mechanical and plant engineering. The main reason for this is probably that - in contrast to positive shaft-hub-connections with a keyway - considerably higher torques can be transmitted and many designs can therefore be made smaller. This correlates with the desire of many users for increasingly compact drives. A more detailed analysis also reveals that at present it is primarily shrink discs in a two-part design that have caught the eye of designers of industrial drive systems. 

Mechanical design engineers planning a drivetrain typically have a range of component options to choose from, and many decisions will boil down to the specific application. When it comes to creating optimal torque output, rotational speed and direction, few decisions are as important in designing high performing gear drives as choosing the right gear for the job. 

Verification of a drive system should include all main elements of the system, which are gears, bearings, shafts, and depending on the application other parts such as screws, couplings, and connections. Gears are clearly the most complicated parts for verification, but in many cases, a gearbox failure has its origin in a shaft or bearing failure. The subject of this paper is to explain how verification of a drive system based on measured or simulated torque-speed-time data can be handled. 

A roller chain can handle a lot of weight, but it has some significant downsides. It’s noisy and needs regular maintenance. It’s expensive, and when it breaks, workers can be injured. Even its performance is a problem.

Siemens Digital Industries Software recently announced that Panasonic Corporation (“Panasonic”) has started to adopt its Teamcenter X software, a Software-as-a-Service (SaaS) cloud product lifecycle management (PLM) solution from the Siemens Xcelerator portfolio of industry software to accelerate its digitalization in product development and design.

Siemens Digital Industries Software offers Zel X software, a next generation browser-based engineering app for streamlining manufacturing and shop-floor operations. Zel X consolidates software for manufacturing, operations, collaboration, design and simulation into a comprehensive, yet lightweight browser-based solution that delivers value instantly.

Ruland Manufacturing continues to expand its motion control coupling product line by introducing bellows couplings with increased misalignment capabilities. These new bellows couplings complement Ruland’s existing high-stiffness line by offering equivalent torque with greater misalignment flexibility.

NSK Ltd. has revised its basic dynamic load ratings, a parameter used to calculate the estimated life of rolling bearings. This revision, which extends the basic rating life (estimated life) of the main types of NSK rolling bearings, applies the “Highly Accurate Bearing Life Prediction Method Applying Ultrasonic Testing (World's First)” announced in March 2023.

The "Engineering Legacy" series gives historical context to mechanical power transmission components featured in PTE. Diamond Chain’s products were integral in many historical breakthroughs, including the Wright Brothers’ first flying machine, Henry Ford’s first automobile, and numerous motorsport champion vehicles.

The miniature GVCM-019-032-02 Linear Voice Coil Servo Motor has been released by Moticont. It is only three-quarters of an inch (19.0 mm) in diameter and features a 0.875 in. (22.2 mm) stroke.  Also called an electric cylinder, this miniature linear servomotor, features a continuous high-force-to-size ratio of 7.4 ounces (2.1 N) and 23.3 ounces (6.5 N) of peak force at a 10 percent duty cycle.
