2. The apparatus system of claim 1 further comprising a second planet locking equipment rotatably mounted within said ring gear in 180° off-arranged relation with regards to the first planet locking equipment, about the full 360° circumference of the ring gear, whereby said initial and second world gears rotate with said ring gear and also rotate about their own respective mounting axes while engaging stated fixed and result spur gear tooth, and whereby in the absence of rotation of the ring gear a rotational pressure applied to said output spur gear will drive said fixed and result spur gear teeth to lock said 1st and second world gears in place.
With reference to the use of the inventive gear system discussed herein, the system provides a simple and low-cost self-lubricating gearbox that can be driven in a forward and reverse direction via an input electric motor shaft, but can’t be back-driven through its output gearing. By virtue of its configuration as a ring gear, the invention can be effectively integrated into any rotating machinery which utilizes a winch/drum. As this kind of, these inventive gear systems have particular application in the field of overhead lifting machinery, although the invention is not so limited. For example, winch machinery that utilizes a cable winding onto a cylindrical or pile-up drum must be in a position to wind in both a clockwise and counterclockwise direction, however, not drop the load. These inventive equipment systems can also be applied to move scenery, create results, 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 enable a compact assembly. The system’s hollow through the guts output spur shaft can complete wiring to a rotating connection, along with the basic insertion of downstream equipment shafts. This would be especially useful for cable drums winding electrified cable, and turntables with electrics/consumer electronics up to speed, for example.
The inventive gear system moreover addresses certain drawbacks of similar existing equipment systems, e.g., vibration and noise conditions that are unacceptable in certain settings (such as during theatrical performances) and burdensome maintenance through the regimen lubrication of the system gears.
To address such disadvantages, briefly described, the self-locking, non-backdrivable gear system of the present invention comprises a main motor input and self-lubricating gear package. The primary motor input is usually 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 gear, and output spur equipment. The input ring gear is mounted around the driveshaft and positioned in meshing engagement with the principal motor input. The ring plate and seal configuration are installed to the ring equipment and seal the parts within the ring gear so as to permit the internal self-lubrication of the gearbox through a volume of lubricant.
One or more world locking gears is rotatably mounted within the band gear, whereby the planet gear rotates with the ring gear and also rotates about its mounting axis. The result spur gear is rotatably installed within the ring gear, in a radially inward, concentric regards to the ring gear, and further includes an result shaft adapted for mounting to the drive shaft. The output spur gear has N+/−X number of gear tooth in meshing engagement with the earth equipment. The fixed spur equipment is fixedly installed around the result shaft and positioned next to the output spur gear. The fixed spur gear has N amount of gear the teeth in meshing engagement with the planet gear tooth. The fixed and output spur gears have considerably similar diameters to allow the fixed and result spur gear the teeth to substantially align while engaging with the planet gear. The fixed and result spur gear tooth each comprise a noise-dampening pressure position configuration to angularly compliment the earth gear teeth.
Functioning, rotation of the primary motor input causes rotation of the ring gear which causes rotation of the earth gear which causes rotation of the output spur gear which in turn causes rotation of the drive shaft. Nevertheless, in the lack of rotation of the band gear, any rotational force put on the output spur gear (electronic.g., via the result shaft) will push the considerably aligned fixed and result gear tooth to lock the earth locking gear in place.
Various other aspects of the machine are provided herein. For example, in an embodiment of the machine having two planet locking gears, the second planet locking gear could be rotatably mounted within the band gear in a 180° off-set relation with respect to the first world locking equipment, about the entire 360° circumference of the ring gear. The 1st and second world gears rotate with the band gear and also rotate about their very own respective mounting axes while engaging the fixed and output spur gear tooth. In the lack of rotation of the band gear, any rotational pressure applied to the output spur gear will power the fixed and result spur gear teeth to lock the 1st and second world gears in place.
The primary motor input may include a sprocket in meshing engagement with a timing belt. The primary motor input may otherwise add a sprocket in meshing engagement with a timing chain. The principal motor input may or else add a sprocket in meshing engagement with a plurality of timing gears.
Each seal of the ring plate and seal configuration could be an O-band or shaft seal. The gearbox may additional comprise a ball bearing ring positioned on the result shaft to facilitate rotation of the result spur equipment. The pressure position configuration may 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 preferably be about 35 degrees. The elements of the gearbox could be made from metal, plastic material, composite, ceramic, wooden, plywood, steel powder, or combinations thereof.
Additional objects, advantages and novel features of today’s invention will be set forth partly in the description which follows, and can in part become apparent to those in the practice of the invention, when regarded as with the attached figures.

Self-locking property of Worm Gear Units
A precondition for the self-locking quality of gear units is a small tooth business lead angle of the worm and therefore an efficiency of η ≤ 0,5 with worm driving. Consequently self-locking gear products are usually uneconomical when high performances and lengthy operating times are required. A worm gear unit is considered self-locking at standstill if, with worm wheel driving, beginning with standstill is unattainable. This is actually the case with ATLANTA wheel units and gear units when the lead angle is definitely <5°. A worm gear unit is considered self-locking from the running condition if the gear unit comes to a standstill whilst being backdriven. This is only feasible with high equipment ratios and very low speeds. Shocks and vibrations can neutralize the self-locking capacity! As a result a self-locking tooth program cannot replace a brake or reverse-stroke locking mechanism. 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.
