2. The gear system of claim 1 further comprising another planet locking equipment rotatably mounted within said ring equipment in 180° off-set relation with regards to the first world locking gear, about the entire 360° circumference of the ring gear, whereby said first and second planet gears rotate with said ring gear and in addition rotate about their own respective installation axes while engaging stated fixed and output spur gear the teeth, and whereby in the absence of rotation of the ring gear a rotational power put on said output spur equipment will force said fixed and output spur gear tooth to lock said 1st and second planet gears in place.
With reference to the use of the inventive gear system discussed herein, the machine offers a simple and low-cost self-lubricating gearbox which can be driven in a forward and reverse direction through an input engine shaft, but cannot be back-driven through its output gearing. By virtue of its configuration as a band gear, the invention can be effectively integrated into any rotating machinery which utilizes a winch/drum. As such, these inventive equipment 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 should be able to wind in both a clockwise and counterclockwise direction, however, not drop the load. 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 superior to existing configurations produced up of friction brakes and worm drive gearboxes. The built-in benefits of a planetary type equipment train further allow for a compact assembly. The system’s hollow through the guts result spur shaft can move wiring to a rotating connection, and also the basic insertion of downstream apparatus shafts. This would be especially useful for cable drums winding electrified cable, and turntables with electrics/electronics up to speed, for example.
The inventive gear system moreover addresses certain disadvantages of similar existing gear systems, e.g., vibration and noise conditions that are unacceptable using settings (such as for example during theatrical performances) and burdensome maintenance through the regimen lubrication of the machine gears.
To address such drawbacks, briefly described, the self-locking, non-backdrivable gear system of today’s invention comprises a principal motor insight and self-lubricating gear box. The primary motor input is usually 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 equipment, and output spur gear. The input ring gear is mounted around the driveshaft and situated in meshing engagement with the principal motor input. The band plate and seal configuration are installed 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 planet locking gears is rotatably mounted within the band gear, whereby the earth equipment rotates with the ring gear and in addition rotates about its own mounting axis. The output spur gear is rotatably installed within the ring gear, in a radially inward, concentric regards to the ring equipment, and further includes an result shaft adapted for installation to the drive shaft. The output spur equipment has N+/−X quantity of gear tooth in meshing engagement with the planet equipment. The fixed spur gear is fixedly mounted around the result shaft and positioned adjacent to the result spur gear. The fixed spur equipment has N amount of gear tooth in meshing engagement with the earth gear tooth. The fixed and result spur gears have considerably similar diameters to allow the fixed and result spur gear teeth to substantially align while engaging with the planet gear. The fixed and result spur gear the teeth each comprise a noise-dampening pressure angle configuration to angularly compliment the planet gear teeth.
In operation, rotation of the principal engine input causes rotation of the band gear which causes rotation of the earth gear which causes rotation of the output spur gear which causes rotation of the drive shaft. Nevertheless, in the absence of rotation of the band gear, any rotational drive put on the output spur equipment (electronic.g., via the result shaft) will push the considerably aligned fixed and output gear the teeth to lock the planet locking gear set up.
Various other aspects of the machine are provided herein. For instance, in an embodiment of the machine having two planet locking gears, the second planet locking gear could be rotatably installed within the ring gear in a 180° off-set up relation with regards to the first planet locking gear, about the entire 360° circumference of the ring gear. The initial and second world gears rotate with the ring gear and in addition rotate about their personal respective installation axes while engaging the set and result spur gear the teeth. In the lack of rotation of the band gear, any rotational force put on the output spur equipment will power the fixed and output spur gear teeth to lock the 1st and second world gears in place.
The primary motor input can include a sprocket in meshing engagement with a timing belt. The primary motor input may or else add a sprocket in 
meshing engagement with a timing chain. The primary 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 could be an O-band or shaft seal. The gearbox may further comprise a ball bearing band positioned on the result shaft to facilitate rotation of the output spur equipment. The pressure position 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 preferably be about 35 degrees. The elements of the gearbox could be made from metal, plastic-type material, composite, ceramic, wooden, plywood, steel powder, or combinations thereof.
Extra objects, advantages and novel features of the present invention will be set forth in part in the description which follows, and can in part become obvious 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 lead angle of the worm and thus an efficiency of η ≤ 0,5 with worm traveling. Consequently self-locking gear products are generally uneconomical when high performances and lengthy operating times are necessary. A worm equipment unit is known as self-locking at standstill if, with worm wheel driving, starting from standstill is not possible. This is the case with ATLANTA wheel models and gear units when the lead angle is usually <5°. A worm gear unit is known as self-locking from the running condition if the gear unit comes to a standstill whilst becoming backdriven. That is only possible with high equipment ratios and very low speeds. Shocks and vibrations can neutralize the self-locking capacity! Therefore 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 very high kinetic energy included, you should furthermore enable a certain running-down time after stopping the insight.
