2. The gear system of claim 1 further comprising another planet locking gear rotatably mounted within stated ring equipment in 180° off-set relation with respect to the first world locking equipment, about the entire 360° circumference of the ring equipment, whereby said first and second planet gears rotate with stated ring gear and also rotate about their personal respective self locking gearbox mounting axes while engaging stated fixed and result spur gear teeth, and whereby in the lack of rotation of the band gear a rotational power applied to said output spur gear will push 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 system provides a simple and low-cost self-lubricating gearbox that can be driven in a forward and reverse direction via an input motor shaft, but can’t be back-driven through its output gearing. By virtue of its configuration as a ring gear, the invention could be effectively integrated into any rotating machinery which utilizes a winch/drum. As such, these inventive equipment systems have particular app in neuro-scientific 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 able to wind in both a clockwise and counterclockwise direction, but not drop the strain. These inventive equipment systems can also be put on 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 made up of friction brakes and worm drive gearboxes. The integrated advantages of a planetary type gear train further enable a compact assembly. The system’s hollow through the center output spur shaft can complete wiring through to a rotating connection, as well as the simple 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 system moreover addresses certain disadvantages of similar existing equipment systems, e.g., vibration and noise issues that are unacceptable using 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 primary motor input and self-lubricating gear package. 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, band plate and seal configuration, planet locking equipment, fixed spur gear, and output spur gear. The input ring gear is installed around the driveshaft and situated in meshing engagement with the principal motor input. The ring plate and seal configuration are mounted to the ring equipment and seal the elements 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 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 relation to the ring gear, and additional includes an result shaft adapted for mounting to the drive shaft. The output spur equipment has N+/−X number of gear teeth in meshing engagement with the earth gear. The fixed spur gear is fixedly installed around the output shaft and positioned adjacent to the result spur equipment. The fixed spur gear has N quantity of gear teeth in meshing engagement with the planet gear tooth. The fixed and output spur gears have considerably similar diameters to permit the fixed and output spur gear tooth to substantially 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 primary engine input causes rotation of the ring gear which in turn 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 force applied to the output spur gear (electronic.g., via the result shaft) will power the considerably aligned fixed and output gear teeth to lock the planet locking gear set up.
Various other aspects of the machine are provided herein. For instance, within an embodiment of the system having two planet locking gears, the next planet locking gear may be rotatably mounted within the ring 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 1st and second planet gears rotate with the ring gear and in addition rotate about their very own respective mounting axes while engaging the set and result spur gear teeth. In the lack of rotation of the band gear, any rotational drive applied to the output spur gear will drive the fixed and output spur gear teeth to lock the initial and second planet gears in place.
The principal motor input may include a sprocket in meshing engagement with a timing belt. The principal motor input may otherwise add 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 band plate and seal configuration may be an O-band or shaft seal. The gearbox may further comprise a ball bearing ring positioned on the output 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 position configuration may most ideally be about 35 degrees. The components of the gearbox could be made from metal, plastic, composite, ceramic, wood, plywood, metallic powder, or combinations thereof.
Additional objects, advantages and novel top features of today’s invention will be established partly 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.

Operation and Maintenance
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 thus an efficiency of η ≤ 0,5 with worm traveling. Consequently self-locking gear devices are generally uneconomical when high performances and lengthy operating times are required. A worm gear unit is considered self-locking at standstill if, with worm wheel traveling, beginning with standstill is impossible. This is actually the case with ATLANTA wheel units and gear products when the lead angle is usually <5°. A worm gear unit is known as self-locking from the working condition if the apparatus unit comes to a standstill whilst being backdriven. This is only possible with high gear ratios and incredibly low speeds. Shocks and vibrations can neutralize the self-locking capacity! For that reason a self-locking tooth program cannot replace a brake or reverse-stroke fasten. In order to avoid overstressing of the worm equipment drive due to the very high kinetic energy involved, you should furthermore allow for a certain running-down period after stopping the input.
