2. The apparatus system of claim 1 further comprising a second planet locking gear rotatably mounted within stated ring equipment in 180° off-set relation with regards to the first planet locking gear, about the entire 360° circumference of the ring equipment, whereby said 1st and second planet gears rotate with said ring gear and also rotate about their personal respective installation axes while engaging stated fixed and output spur gear teeth, and whereby in the absence of rotation of the ring gear a rotational pressure put on said output spur equipment will force said fixed and result spur gear the teeth to lock said initial and second planet gears in place.
With reference to the application of the inventive gear system discussed herein, the system provides a simple and low-cost self-lubricating gearbox which can be driven in a forward and invert direction via an input engine shaft, but cannot 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 gear systems have particular software in the field of overhead lifting machinery, although the invention is not 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, however, not drop the strain. These inventive gear systems can also be applied to move scenery, create results, 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 integrated advantages of a planetary type gear train further enable a compact assembly. The system’s hollow through the guts result spur shaft can complete wiring to a rotating connection, as well as the simple insertion of downstream tools shafts. This might be especially useful for cable drums winding electrified cable, and turntables with electrics/electronics on board, for example.
The inventive gear program moreover addresses certain disadvantages 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 regimen lubrication of the system gears.
To address such drawbacks, briefly described, the self-locking, non-backdrivable gear system of the present invention comprises a main motor input and self-lubricating gear box. The primary motor input can be adapted for rotation of the gearbox about the axis of a drive shaft. The gearbox comprises an input ring gear, ring plate and seal configuration, planet locking equipment, fixed spur gear, and output spur gear. The input ring gear is installed around the driveshaft and positioned in meshing engagement with the principal motor input. The band plate and seal configuration are mounted to the ring gear and seal the parts 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 gear rotates with the band gear and in addition rotates about its own mounting axis. The result spur gear is rotatably installed within the ring gear, in a radially inward, concentric relation to the ring equipment, and further includes an output shaft adapted for mounting to the drive shaft. The output spur equipment has N+/−X quantity of gear the teeth in meshing engagement with the earth equipment. The fixed spur equipment is fixedly installed around the output shaft and positioned adjacent to the output spur equipment. The fixed spur equipment has N number of gear tooth in meshing engagement with the planet gear the teeth. 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 earth equipment. The fixed and result spur gear tooth each comprise a noise-dampening pressure position configuration to angularly compliment the planet gear teeth.
In operation, rotation of the primary motor input causes rotation of the band gear which causes rotation of the earth 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 band gear, any rotational force put on the output spur equipment (electronic.g., via the result shaft) will power the considerably aligned fixed and result gear teeth to lock the earth locking gear set up.
Additional aspects of the system are provided herein. For instance, in an embodiment of the system having two world locking gears, the second planet locking gear could be rotatably mounted within the ring gear in a 180° off-arranged relation with regards to the first world locking equipment, about the entire 360° circumference of the ring gear. The initial and second planet gears rotate with the band gear and also rotate about their own respective mounting axes while engaging the fixed and result spur gear the teeth. In the absence of rotation of the ring gear, any rotational push put on the output spur equipment will force the fixed and output spur gear the teeth to lock the first and second world gears in place.
The primary motor input may include a sprocket in meshing engagement with a timing belt. The principal motor input may or else 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 could be an O-ring or shaft seal. The gearbox may additional comprise a ball bearing band 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 position configuration may more preferably be from about 40 degrees to 30 degrees. The pressure angle configuration may most ideally end up being about 35 degrees. The components of the gearbox could be made from metal, plastic-type material, composite, ceramic, wood, plywood, metallic powder, or combinations thereof.
Extra objects, advantages and novel 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 regarded with the attached figures.

Operation and Maintenance
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 therefore an efficiency of η ≤ 0,5 with worm generating. Consequently self-locking gear systems are generally uneconomical when high performances and long operating times are required. A worm gear unit is known as self-locking at standstill if, with worm wheel generating, beginning with standstill is not possible. This is the case with ATLANTA wheel sets and gear devices when the lead angle is usually <5°. A worm gear unit is considered self-locking from the operating condition if the gear unit comes to a standstill whilst getting backdriven. That is only possible with high equipment ratios and incredibly 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. To avoid overstressing of the worm gear drive because of the very high kinetic energy involved, you should furthermore allow for a certain running-down period after stopping the input.
