A self-locking non-backdrivable gear system, comprising: a. a main motor input adapted for rotation of a self-lubricating gearbox about the axis of a drive shaft; b. said gearbox comprises: i. an insight ring equipment mounted around said driveshaft and positioned in meshing engagement with said primary motor insight; ii. a band plate and seal configuration installed to said ring gear for sealing parts within said ring gear to allow the internal self-lubrication of stated gearbox through a level of lubricant; iii. a world locking gear rotatably mounted within said ring gear, whereby said planet gear rotates with said ring equipment and in addition rotates about its own mounting axis; iv. an output spur equipment rotatably mounted within stated ring gear in a radially inward, concentric relation to said ring gear and additional includes an output shaft adapted for installation to stated drive shaft, stated output spur gear has N +/−X amount of gear tooth in meshing engagement with said planet gear; v. a fixed spur gear fixedly mounted around said output shaft and positioned adjacent to said result spur equipment, said fixed spur gear has N quantity of gear the teeth in meshing engagement with said planet equipment; and vi. wherein said fixed and result spur gears have substantially similar diameters to allow said fixed and output spur gear teeth to considerably align while engaging with said planet gear, vii. wherein said set and output spur gear tooth comprise a noise-dampening pressure position configuration which angularly compliment stated planet gear the teeth, viii. whereby rotation of said primary motor input causes rotation of stated ring gear which in turn causes rotation of stated planet gear which causes rotation of stated output spur gear which in turn causes rotation of said drive shaft, and whereby in the lack of rotation of stated ring gear a rotational drive applied to said output spur gear forces the substantially aligned said fixed and output gear teeth to lock said planet locking gear in place.
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 respect to the first world locking gear, about the entire 360° circumference of the ring equipment, whereby said 1st and second planet gears rotate with stated ring gear and also rotate about their own respective installation axes while engaging stated fixed and output spur gear tooth, and whereby in the absence of rotation of the band gear a rotational push put on said output spur gear will push said fixed and output spur gear tooth to lock said first and second planet 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 invert direction via an input motor shaft, but cannot be back-driven through its output gearing. By virtue of its configuration as a band gear, the invention can be effectively built-into any rotating machinery which utilizes a winch/drum. As such, these inventive gear systems have particular program 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 load. These inventive gear systems can also be applied to move scenery, create effects, and manipulate overhead light and machinery during theatrical performances.
Regarding machinery that uses chain or screw jack components, a non-back driving, self-locking gearbox would offer benefits more advanced than existing configurations produced up of friction brakes and worm drive gearboxes. The included advantages of a planetary type gear train further allow for a compact assembly. The system’s hollow through the center output spur shaft can pass wiring to a rotating connection, and also the basic insertion of downstream tools shafts. This would be particularly useful for cable drums winding electrified cable, and turntables with electrics/electronics up to speed, for example.
The inventive gear program moreover addresses certain disadvantages of similar existing equipment systems, e.g., vibration and noise conditions that are unacceptable using settings (such as for example during theatrical performances) and burdensome maintenance through the routine lubrication of the machine gears.
To address such disadvantages, briefly described, the self-locking, non-backdrivable gear program of the present invention comprises a principal motor input and self-lubricating gear box. The primary motor insight is usually adapted for rotation of the gearbox about the axis of a drive shaft. The gearbox comprises an insight ring gear, ring plate and seal configuration, planet locking equipment, fixed spur gear, and output spur equipment. The input ring equipment is installed around the driveshaft and situated in meshing engagement with the principal motor input. The ring plate and seal configuration are installed to the ring gear and seal the components within the ring gear so as to allow the inner self-lubrication of the gearbox through a level of lubricant.
One or more planet locking gears is rotatably mounted within the ring gear, whereby the planet equipment rotates with the band gear and also rotates about its own mounting axis. The result spur gear is rotatably mounted within the ring gear, in a radially inward, concentric relation to the ring equipment, and further includes an output shaft adapted for installation to the drive shaft. The output spur gear has N+/−X quantity of gear tooth in meshing engagement with the earth gear. The fixed spur equipment is fixedly installed around the result shaft and positioned adjacent to the output spur equipment. The fixed spur gear has N amount of gear tooth in meshing engagement with the planet gear the teeth. The fixed and result spur gears have substantially similar diameters to permit the fixed and result spur gear teeth to substantially align while engaging with the earth gear. 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 engine 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. However, in the lack of rotation of the ring gear, any rotational drive applied to the output spur gear (e.g., via the output shaft) will pressure the considerably aligned fixed and result gear teeth to lock the planet locking gear in place.
Additional aspects of the machine are provided herein. For instance, in an embodiment of the system having two planet locking gears, the second planet locking gear could be rotatably installed within the band gear in a 180° off-arranged relation with respect to the first planet locking gear, about the full 360° circumference of the ring gear. The initial and second world gears rotate with the ring gear and also rotate about their very own respective installation axes while engaging the fixed and output spur gear teeth. In the lack of rotation of the ring gear, any rotational drive put on the output spur equipment will force the fixed and result spur gear tooth to lock the first and second planet 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 otherwise add a sprocket in meshing engagement with a plurality of timing gears.
Each seal of the band plate and seal configuration may be an O-band or shaft seal. The gearbox may further comprise a ball bearing band positioned on the output shaft to facilitate rotation of the output spur gear. The pressure angle configuration could 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 position configuration may most preferably become about 35 degrees. The elements of the gearbox could be made from metal, plastic-type material, composite, ceramic, wood, plywood, metal powder, or combinations thereof.
Extra objects, advantages and novel top features of today’s invention will be set forth partly in the description which follows, and will in part become obvious 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 equipment units is a small tooth lead angle of the worm and thus an efficiency of η ≤ 0,5 with worm traveling. Consequently self-locking gear units are generally uneconomical when high performances and lengthy operating times are needed. A worm gear unit is considered self-locking at standstill if, with worm wheel traveling, beginning with standstill is impossible. This is the case with ATLANTA wheel pieces and gear units when the lead position is <5°. A worm gear unit is considered self-locking from the operating condition if the apparatus unit involves a standstill whilst being backdriven. This is only possible with high equipment ratios and very 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 because of the high kinetic energy included, you should furthermore enable a certain running-down period after stopping the input.
