2. The apparatus system of claim 1 further comprising another planet locking gear rotatably mounted within said ring equipment in 180° off-set relation with regards to the first planet locking gear, about the entire 360° circumference of the ring equipment, whereby said first and second planet gears rotate with said ring gear and also rotate about their very own respective mounting axes while engaging stated fixed and result spur gear teeth, and whereby in the absence of rotation of the band gear a rotational push put on said output spur equipment will power said fixed and result spur gear tooth to lock said 1st and second world gears in place.
With reference to the application of the inventive gear system discussed herein, the system provides a simple and low-cost self-lubricating gearbox which can be driven in a forward and invert direction via an input engine shaft, but cannot be back-driven through its output gearing. By virtue of its configuration as a ring gear, the invention can be effectively built-into any rotating machinery which utilizes a winch/drum. As this kind of, these inventive equipment systems have particular application in neuro-scientific overhead lifting machinery, although the invention isn’t so limited. For instance, 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 strain. These inventive gear systems can also be applied to move scenery, create effects, and manipulate overhead light and machinery during theatrical performances.
In the case of machinery that uses chain or screw jack components, a non-back driving, self-locking gearbox would offer benefits more advanced than existing configurations made up of friction brakes and worm drive gearboxes. The built-in benefits of a planetary type equipment train further enable a concise assembly. The system’s hollow through the guts result spur shaft can complete wiring to a rotating connection, as well as the simple insertion of downstream equipment shafts. This would be especially useful for cable drums winding electrified cable, and turntables with electrics/electronic devices on board, 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 drawbacks, briefly described, the self-locking, non-backdrivable gear system of the present invention comprises a principal motor input and self-lubricating gear box. The primary motor input is adapted for rotation of the gearbox about the axis of a drive shaft. The gearbox comprises an insight ring gear, band plate and seal configuration, planet locking equipment, fixed spur gear, and output spur equipment. The input ring equipment is installed around the driveshaft and positioned in meshing engagement with the primary motor input. The band plate and seal configuration are mounted to the ring equipment and seal the parts within the ring gear so as to permit the inner 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 band gear and also rotates about its mounting axis. The result spur gear is rotatably mounted within the ring equipment, in a radially inward, concentric relation to the ring gear, and further includes an result shaft adapted for installation to the drive shaft. The output spur gear has N+/−X amount of gear teeth in meshing engagement with the earth gear. The fixed spur equipment is fixedly mounted around the output shaft and positioned adjacent to the output spur gear. The fixed spur equipment has N amount of gear teeth in meshing engagement with the planet gear tooth. The fixed and result spur gears have substantially similar diameters to permit the fixed and output spur gear tooth to substantially align while engaging with the planet equipment. The fixed and result spur gear tooth each comprise a noise-dampening pressure angle configuration to angularly compliment the planet gear teeth.
In operation, rotation of the primary motor input causes rotation of the band gear which causes rotation of the planet gear which causes rotation of the output spur gear which in turn causes rotation of the drive shaft. Nevertheless, in the absence of rotation of the ring gear, any rotational force put on the output spur gear (e.g., via the result shaft) will push the substantially aligned fixed and output gear tooth to lock the planet locking gear in place.
Other aspects of the machine are provided herein. For example, in an embodiment of the machine self locking gearbox having two world locking gears, the second planet locking gear could be rotatably installed within the ring gear in a 180° off-set relation with respect to the first world locking gear, about the full 360° circumference of the ring gear. The first and second planet gears rotate with the ring gear and also rotate about their own respective installation axes while engaging the fixed and result spur gear the teeth. In the lack of rotation of the band gear, any rotational pressure applied to the output spur equipment will power the fixed and result spur gear teeth to lock the initial 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 include a sprocket in meshing engagement with a timing chain. The principal motor input may or else include a sprocket in meshing engagement with a plurality of timing gears.
Each seal of the ring plate and seal configuration may be an O-ring or shaft seal. The gearbox may further comprise a ball bearing ring positioned on the output shaft to facilitate rotation of the result spur gear. The pressure angle configuration may be from about 45 degrees to about 25 degrees. The pressure angle configuration may more preferably be from about 40 degrees to 30 degrees. The pressure angle configuration may most ideally become about 35 degrees. The elements of the gearbox could be made from metal, plastic-type, composite, ceramic, wood, plywood, steel powder, or combinations thereof.
Extra objects, advantages and novel features of today’s invention will be established 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.

Self-locking property of Worm Gear Units
A precondition for the self-locking quality of equipment units is a little tooth business lead angle of the worm and therefore an efficiency of η ≤ 0,5 with worm traveling. Consequently self-locking gear models are usually uneconomical when high performances and long operating times are needed. A worm gear unit is known as self-locking at standstill if, with worm wheel generating, beginning with standstill is extremely hard. This is the case with ATLANTA wheel units and gear models when the lead position is definitely <5°. A worm gear unit is known as self-locking from the running condition if the apparatus unit involves a standstill whilst getting backdriven. This is only feasible with high equipment ratios and incredibly low speeds. Shocks and vibrations can neutralize the self-locking capacity! Consequently a self-locking tooth program cannot replace a brake or reverse-stroke locking mechanism. In order to avoid overstressing of the worm equipment drive due to the high kinetic energy involved, you should furthermore enable a certain running-down time after stopping the insight.
