2. The gear system of claim 1 further comprising another planet locking equipment rotatably mounted within said ring gear in 180° off-arranged relation with respect to the first planet locking gear, about the entire 360° circumference of the ring gear, whereby said first and second world gears rotate with stated ring gear and also rotate about their personal respective installation axes while engaging said fixed and result spur gear tooth, and whereby in the lack of rotation of the ring gear a rotational push applied to said output spur gear will force said fixed and output spur gear tooth to lock said initial 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 electric motor shaft, but can't 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 this kind of, these inventive equipment 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 should be in a self locking gearbox position to wind in both a clockwise and counterclockwise direction, but not drop the load. These inventive gear systems can also be applied to 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 made up of friction brakes and worm drive gearboxes. The built-in benefits of a planetary type gear train further allow for a concise assembly. The system's hollow through the center result spur shaft can complete wiring to a rotating connection, along with the basic insertion of downstream tools shafts. This would be especially useful for cable drums winding electrified cable, and turntables with electrics/electronic devices up to speed, for example.
The inventive gear program moreover addresses certain drawbacks of similar existing gear systems, e.g., vibration and noise conditions that are unacceptable using settings (such as during theatrical performances) and burdensome maintenance through the program 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 insight and self-lubricating gear package. The primary motor input can be 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 equipment, and output spur gear. 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 mounted to the ring gear and seal the parts 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 equipment rotates with the band gear and in addition rotates about its mounting axis. The result spur equipment is rotatably installed within the ring gear, in a radially inward, concentric regards to the ring gear, and further includes an output shaft adapted for installation to the drive shaft. The output spur equipment has N+/−X amount of gear tooth in meshing engagement with the planet gear. The fixed spur gear is fixedly installed around the result shaft and positioned next to the output spur equipment. The fixed spur equipment has N amount of gear teeth in meshing engagement with the earth gear the teeth. The fixed and result spur gears have substantially similar diameters to permit the fixed and output spur gear teeth to considerably align while engaging with the planet equipment. The fixed and output spur gear tooth each comprise a noise-dampening pressure angle configuration to angularly compliment the earth gear teeth.
Functioning, rotation of the principal motor 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. However, in the absence of rotation of the band gear, any rotational drive applied to the output spur gear (e.g., via the result shaft) will power the substantially aligned fixed and output gear the teeth to lock the planet locking gear in place.
Additional aspects of the system 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-set relation with regards to the first world locking equipment, about the full 360° circumference of the ring gear. The first and second world gears rotate with the ring gear and in addition rotate about their personal respective mounting axes while engaging the set and result spur gear tooth. In the lack of rotation of the ring gear, any rotational pressure applied to the output spur equipment will force the fixed and result spur gear tooth to lock the first and second planet gears in place.
The principal 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 ring plate and seal configuration could 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 output spur gear. The pressure angle 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 angle configuration may most preferably become about 35 degrees. The components of the gearbox could be made from metal, plastic-type, composite, ceramic, wooden, plywood, metal powder, or combinations thereof.
Additional objects, advantages and novel top 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 considered 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 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 extremely hard. This is actually the case with ATLANTA wheel pieces and gear models when the lead position is definitely Standard Bevel Gear Units
