2. The apparatus system of claim 1 further comprising a second planet locking gear rotatably mounted within said ring gear in 180° off-set relation with respect to the first world locking gear, about the full 360° circumference of the ring gear, whereby said initial and second world gears rotate with said ring gear and also rotate about their very own respective mounting axes while engaging stated fixed and output spur gear teeth, and whereby in the lack of rotation of the band gear a rotational drive applied to said output spur gear will pressure said fixed and result spur gear teeth to lock said 1st and second world gears in place.
With reference to the application of the inventive gear system discussed herein, the system offers a simple and low-cost self-lubricating gearbox which can be driven in a forward and invert direction via 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 such, these inventive gear systems have particular software 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 should be able to wind in both a clockwise and counterclockwise direction, but not drop the load. These inventive equipment systems can also be put on 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 made up of friction brakes and worm drive gearboxes. The built-in advantages of a planetary type equipment train further allow for a concise assembly. The system’s hollow through the center output spur shaft can move wiring through to a rotating connection, and also the simple 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 disadvantages of similar existing gear systems, e.g., vibration and noise conditions that are unacceptable in certain settings (such as during theatrical performances) and burdensome maintenance through the routine lubrication of the system gears.
To address such disadvantages, briefly described, the self-locking, non-backdrivable gear program of the present invention comprises a primary motor input and self-lubricating gear container. The primary motor insight is adapted for rotation of the gearbox about the axis of a drive shaft. The gearbox comprises an input ring gear, band plate and seal configuration, planet locking gear, fixed spur gear, and output spur gear. The input ring gear is installed around the driveshaft and positioned in meshing engagement with the primary motor input. The ring plate and seal configuration are mounted to the ring equipment and seal the elements within the ring equipment so as to allow the inner 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 ring gear and in addition rotates about its mounting axis. The output spur equipment is rotatably installed within the ring gear, in a radially inward, concentric regards 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 planet gear. The fixed spur equipment is fixedly mounted around the output shaft and positioned adjacent to the result spur equipment. The fixed spur gear has N amount of gear teeth in meshing engagement with the earth gear teeth. The fixed and result spur gears have substantially similar diameters to allow the fixed and output spur gear tooth to substantially align while engaging with the earth 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 engine input causes rotation of the band gear which causes rotation of the planet gear which in turn 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 applied to the output spur gear (electronic.g., via the output shaft) will force the substantially aligned fixed and result gear the teeth to lock the planet locking gear in place.
Other aspects of the machine are provided herein. For example, in an embodiment of the machine having two world locking gears, the second planet locking gear could be rotatably mounted within the ring gear in a 180° off-set 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 in addition rotate about their very own respective mounting axes while engaging the set and output spur gear the teeth. In the absence of rotation of the ring gear, any rotational force applied to the output spur gear will pressure the fixed and output spur gear the teeth to lock the 1st and second world gears in place.
The principal motor input can include a sprocket in meshing engagement with a timing belt. The principal motor input may otherwise include a sprocket in meshing engagement with a timing chain. The principal motor input may or else 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-band or shaft seal. The gearbox may additional comprise a ball bearing ring positioned on the result shaft to facilitate rotation of the result spur gear. 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 components of the gearbox may be made from metal, plastic-type material, composite, ceramic, wood, plywood, metal powder, or combinations thereof.
Additional objects, advantages and novel features of the present 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.

Operation and Maintenance
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 therefore an efficiency of η ≤ 0,5 with worm driving. Consequently self-locking gear devices are usually uneconomical when high performances and long operating times are required. A worm equipment unit is known as self-locking at standstill if, with worm wheel generating, beginning with standstill is extremely hard. This is actually the case with ATLANTA wheel models and gear models when the lead position is <5°. A worm gear unit is considered self-locking from the running condition if the apparatus unit involves a standstill whilst getting backdriven. That is only possible with high gear ratios and very 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 because of the high kinetic energy involved, you should furthermore enable a certain running-down period after stopping the insight.
