2. The gear system of claim 1 further comprising another planet locking gear rotatably mounted within said ring gear in 180° off-established relation with regards to the first world locking equipment, about the full 360° circumference of the ring gear, whereby said first and second planet gears rotate with stated ring gear and in addition rotate about their own respective installation axes while engaging stated fixed and output spur gear teeth, and whereby in the lack of rotation of the band gear a rotational power applied to said output spur equipment will pressure said fixed and output spur gear the teeth to lock said 1st and second world gears in place.
With reference to the use of the inventive gear system discussed herein, the machine provides a simple and low-cost self-lubricating gearbox which can be driven in a forward and invert direction via an input motor shaft, but cannot be back-driven through its output gearing. By virtue of its configuration as a ring gear, the invention could be effectively integrated into any rotating machinery which utilizes a winch/drum. As such, these inventive gear systems have particular software in neuro-scientific overhead lifting machinery, although the invention isn’t so limited. For example, winch machinery that utilizes a cable winding onto a cylindrical or pile-up drum must be able to wind in both a clockwise and counterclockwise direction, however, not drop the strain. These inventive gear systems may also be put on move scenery, create effects, and manipulate overhead lighting and machinery during theatrical performances.
Regarding machinery that uses chain or screw jack components, a non-back driving, self-locking gearbox would offer benefits superior to existing configurations produced up of friction brakes and worm drive gearboxes. The integrated benefits of a planetary type gear train further allow for a concise assembly. The system’s hollow through the guts result spur shaft can complete wiring to a rotating connection, and also the simple insertion of downstream equipment shafts. This would be particularly useful for cable drums winding electrified cable, and turntables with electrics/consumer electronics up to speed, for example.
The inventive gear program moreover addresses certain drawbacks of similar existing equipment systems, e.g., vibration and noise issues that are unacceptable in certain settings (such as for example during theatrical performances) and burdensome maintenance through the routine lubrication of the system gears.
To address such drawbacks, briefly described, the self-locking, non-backdrivable gear program of the present invention comprises a major motor insight and self-lubricating gear box. The primary motor input can be adapted for rotation of the gearbox about the axis of a drive shaft. The gearbox comprises an input ring gear, band plate and seal configuration, planet locking gear, fixed spur equipment, and output spur equipment. The input ring gear is installed around the driveshaft and positioned in meshing engagement with the primary motor input. The ring plate and seal configuration are mounted to the ring equipment and seal the components within the ring gear so as to permit the internal self-lubrication of the gearbox through a level of lubricant.
One or more world locking gears is rotatably mounted within the ring gear, whereby the planet gear rotates with the band gear and also rotates about its mounting axis. The result spur equipment is rotatably mounted within the ring gear, in a radially inward, concentric regards to the ring equipment, and additional includes an output shaft adapted for mounting to the drive shaft. The output spur gear has N+/−X number of gear teeth in meshing engagement with the earth gear. The fixed spur gear is fixedly installed around the output shaft and positioned adjacent to the output spur gear. The fixed spur gear has N number of gear tooth in meshing engagement with the planet gear the teeth. The fixed and result spur gears have substantially similar diameters to allow the fixed and output spur gear teeth to substantially align while engaging with the planet equipment. The fixed and output spur gear teeth each comprise a noise-dampening pressure position configuration to angularly compliment the earth gear teeth.
Functioning, rotation of the principal electric motor input causes rotation of the ring gear which in turn causes rotation of the planet gear which in turn causes rotation of the output spur gear which causes rotation of the drive shaft. However, in the absence of rotation of the ring gear, any rotational force applied to the output spur gear (electronic.g., via the result shaft) will power the considerably aligned fixed and result gear the teeth to lock the planet locking gear in place.
Various other aspects of the machine are provided herein. For instance, in an embodiment of the system having two world locking gears, the next planet locking gear could be rotatably installed within the ring gear in a 180° off-set relation with regards to the first world locking gear, about the entire 360° circumference of the ring gear. The 1st and second world gears rotate with the ring gear and also rotate about their own respective installation axes while engaging the fixed and output spur gear tooth. In the absence of rotation of the band gear, any rotational pressure put on the output spur gear will force the fixed and result spur gear tooth to lock the 1st and second world gears in place.
The principal motor input may include a sprocket in meshing engagement with a timing belt. The principal motor input may or else add a sprocket in meshing engagement with a timing chain. The principal motor input may otherwise include a sprocket in meshing engagement with a plurality of timing gears.
Each seal of the band plate and seal configuration may be an O-ring or shaft seal. The gearbox may additional comprise a ball bearing ring positioned on the output shaft to facilitate rotation of the output spur gear. The pressure position configuration could be from about 45 degrees to about 25 degrees. The pressure position configuration may more preferably be from about 40 degrees to 30 degrees. The pressure position configuration may most ideally be about 35 degrees. The parts of the gearbox may be made from metal, plastic, composite, ceramic, wood, plywood, metal powder, or combinations thereof.
Additional objects, advantages and novel top features of the present invention will be set forth in part in the description which follows, and will in part become apparent to those in the practice of the invention, when regarded with the attached figures.

Operation and Maintenance
Self-locking property of Worm Gear Units
A precondition for the self-locking quality of gear units is a little tooth lead angle of the worm and thus an efficiency of η ≤ 0,5 with worm generating. Consequently self-locking gear devices are usually uneconomical when high performances and lengthy operating times are needed. A worm gear unit is known as self-locking at standstill if, with worm wheel generating, beginning with standstill is impossible. This is the case with ATLANTA wheel units and gear systems when the lead angle is <5°. A worm gear unit is considered self-locking from the operating condition if the apparatus unit involves a standstill whilst becoming backdriven. This is only possible with high equipment ratios and incredibly low speeds. Shocks and vibrations can neutralize the self-locking capacity! Therefore a self-locking tooth system cannot replace a brake or reverse-stroke fasten. In order to avoid overstressing of the worm gear drive because of the very high kinetic energy included, you should furthermore allow for a certain running-down time after stopping the input.
