The 2 Motor Gearbox - Through Bore is compatible with the REV ION System. This two motor into one output gearbox allows the user to adjust the gear ratio by changing pinion and cluster gear (12:60, 18:54, 24:48, or 36:36). The output shaft is 1/2in Hex through bore, and output gears have a MAXSpline bore. The motor plate contains 2 Pairs of 2in pitch #10-32 tapped holes for mounting the REV Through Bore Encoder, and the output plate contains an array of holes for mounting to structure, as well as mounting as an input to the MAXPlanetary. The 5:1 Ratio (60:12) can be micro adjusted slightly larger by swapping the 12T pinion with 11T or 10T.
Aviation Week reporting shows the newly released investigation was one of at least four such gearbox problems that occurred in serious crashes of both Marine Corps and U.S. Air Force V-22s last year. While the new accident investigation board report into the June 2022 incident states the HCE was the primarily cause of that crash, an investigation into another 2022 fatal MV-22 crash in Norway states a gearbox problem did occur but blamed that mishap on pilot error.
For the U.S. Air Force, at least two proprotor gearbox problems forced down V-22s, according to information on the Class A mishaps by Aviation Week---incidents defined as causing at least $2.5 million in damage or severe injuries or deaths. One high-profile incident in August 2022 in Norway prompted the Air Force to stand down its operations. This came after another incident on May 17, 2022. Investigations into these incidents have not been released, and there were multiple other similar incidents, including another USAF CV-22 forced to land on July 8, 2022, and an MV-22B experienced an engine fire while landing in October 2022.
The IS multi-turn gearbox series are multi-turn (rotary) devices intended for the operation of gate, globe, sluice and penstock valves. These gearboxes are suitable for manual and motorised applications.
The NDF planetary gearbox was developed specifically for use in Delta robots and is characterized in particular by high torsional stiffness, high torque, low torsional backlash, reduced inertia and a modified sealing concept.

The newly developed PLQE040 and PLFE055 gearboxes extend the proven PLQE and PLFE Economy series by two smaller frame sizes. These models thus fulfill the wish of many machine builders wanting gearboxes suitable for more compact, lighter servo drives.
The PM2 pinion series offers even more choices and even greater flexibility when selecting gearbox/pinion combinations for rack-and-pinion drives. Thanks to their smaller diameter, depending on the combination, the pinions allow a feed rate more than three times higher than was previously possible.
As a follow-up to the NGV, the planetary gearbox for industrial automated guided vehicle, and the hygienic HLAE, Neugart now has, with the new NDF, an additional gearbox solution for a specific area of application in its portfolio: the newly developed product has been designed specifically for use in Delta robot arm drives.
The newly developed PLQE040 and PLFE055 gearboxes extend the proven Economy series PLQE and PLFE by two smaller frame sizes and round out the corresponding portfolio downwards. This is Neugart's response to the desire of many machine manufacturers for more compact, lightweight servo drives.

On the Original Prusa MK4, a gearbox alignment is necessary for user-assembled or serviced gearboxes. This procedure is part of the Selftest or can be initiated from LCD menu -> Control -> Gears Calibration.
Development testing of the first prototype gearbox, focused on validation, endurance and reliability, began in 2017 at the dedicated PGB test facility in Dahlewitz. During a rigorous test regime, the power gearbox has since accumulated more than 650 testing hours and proven its capability of managing the equivalent power of an entire grid of Formula 1 cars.
To adapt the commonly employed laser sources and scanners for high frame rate imaging, we have developed an optical gearbox to overcome the scan frequency and scan throughput tradeoff of common scanners. The core idea is to let the common optical scanners operate at the optimal condition that yields the highest throughput and to leverage the optical gearbox to tailor the scanning pattern to a usable form for high frame rate applications. The basic function of the optical gearbox is to enable the flexibility to convert a large-angle scanning into a user-defined number of short-range scanning. In such a way, zooming in by a factor of n leads to an n times faster line rate and an n2 times faster frame rate, which is n times faster than that of the conventional multiphoton imaging systems. The essence of an optical gearbox contains three components: optical path separation, path spacing amplification, and sequential input to the scanner. Take a 24 optical degree scanner as an example, we first employ a fast-switching device (e.g. acousto-optic deflector, AOD) to switch the laser beam towards 8 different angles (i.e. achieving optical path separation). Due to the limited time-bandwidth product of the AOD, the angular spacing (number of angularly resolvable spots) between the adjacent paths is very limited. In the second step, we employ optical components to amplify the angular spacing between these 8 paths before the beams arrive on the laser scanner such that their angular spacing on the scanner is equal to 3 optical degrees (i.e. achieving path spacing amplification). In the final step, we synchronize the sequential beam path switching with the scanning of the scanner such that a single full-range line scan becomes 8 sequential line scans, each with 1/8 of the original scan range. Thus, we obtain 8 times line rate acceleration without a tradeoff in throughput. As the path switching is electronically controlled, we have the freedom to adjust the line rate or scan range at will. For example, instead of visiting all 8 paths sequentially, we can command the laser beam to visit the odd number of paths and therefore accelerate the line rate by a factor of 4, each with 1/4 of the full scan range. With the throughput conservation and the rate and range flexibility considered, this mechanism bears similarity to that of the mechanical gearbox. Thus, we named this method optical gearbox. In this work, we employ the optical gearbox-based imaging system for 2D and 3D multiscale measurement of fast biological events within live animals.
One inherent advantage of such high-rate spatial scanning is that the laser pulses were separated in time and space (spatial spacing of the pulses equal to half of the spatial resolution), allowing dark-state relaxation of the fluorophores, and reducing the photobleaching rate49. As an example, we performed in vivo imaging of the dendritic structures of Thy1-eGFP mice and compared the photobleaching rate obtained by the gearbox system and by the galvo scanning with the same excitation parameters (Supplementary Fig. 5). Statistical analysis showed a severalfold increase in the fluorescence decay time, which demonstrated the benefit of the gearbox-based high-rate imaging for long-duration recording applications.
In summary, we developed an optical gearbox to achieve high-rate imaging based on the commonly available imaging hardware. As an add-on module to a laser scanning microscope system, the gearbox can flexibly adjust the imaging frame rate and FOV with the same high data throughput. Different from conventional multiphoton imaging systems, zooming in the image by a factor of n with the gearbox speeds up the imaging by n2 times. Experimentally, we demonstrated in vivo 2D and 3D calcium imaging of neurons and 2D blood flow speed imaging. As the gearbox preserved the inherent two-photon focus quality, confinement, and contrast, the high-rate imaging was applicable to fine dendritic structures. Moreover, the spatiotemporally spaced laser pulses prolong the fluorescence decay time during long recording sessions. With its flexibility and compatibility with widely available imaging components, the optical gearbox holds great potential to broadly enable high-rate functional recording in a wide range of applications.
To provide a user-friendly interface, we designed the GUI such that its function and appearance were similar to that of the widely used open-source laser scanning microscopy control software ScanImage (Supplementary Fig. 3). The GUI allowed users to conveniently set the gearbox zoom setting (e.g. 2x, 4x, 8x), continuously view the real-time images, and record a user-defined number of images over time.
