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 world locking gear, about the full 360° circumference of the ring equipment, whereby said initial and second world gears rotate with said ring gear and in addition rotate about their personal respective mounting axes while engaging stated fixed and result spur gear the teeth, and whereby in the lack of rotation of the band gear a rotational force put on said output spur equipment will power said fixed and output 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 provides a simple and low-cost self-lubricating gearbox that 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 built-into any rotating machinery which utilizes a winch/drum. As such, these inventive gear systems have particular app 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 must be in a position to wind in both a clockwise and counterclockwise direction, but not drop the load. These inventive gear systems may also be put on move scenery, create results, 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 integrated benefits of a planetary type gear train further allow for a concise assembly. The system’s hollow through the guts result spur shaft can complete wiring through to a rotating connection, as well as the simple insertion of downstream equipment 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 in certain settings (such as for example during theatrical performances) and burdensome maintenance through the routine lubrication of the machine gears.
To address such drawbacks, briefly described, the self-locking, non-backdrivable gear program of today’s invention comprises a main motor insight and self-lubricating gear box. The primary motor input is definitely 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 equipment. 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 components within the ring gear so as to permit the inner self-lubrication of the gearbox through a volume of lubricant.
One or more planet locking gears is rotatably mounted within the band gear, whereby the earth equipment rotates with the ring gear and also 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 equipment, and further includes an output shaft adapted for mounting to the drive shaft. The output spur gear has N+/−X number of gear teeth in meshing engagement with the earth gear. The fixed spur equipment is fixedly installed around the output shaft and positioned adjacent to the result spur gear. The fixed spur gear has N quantity of gear tooth in meshing engagement with the planet gear teeth. The fixed and output spur gears have substantially similar diameters to permit the fixed and result spur gear the teeth to considerably align while engaging with the earth gear. The fixed and result spur gear teeth each comprise a noise-dampening pressure position configuration to angularly compliment the planet gear teeth.
In operation, rotation of the primary engine input causes rotation of the ring gear which in turn 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 ring gear, any rotational pressure put on the output spur equipment (electronic.g., via the output shaft) will force the considerably aligned fixed and result gear tooth to lock the earth locking gear in place.
Other aspects of the system are provided herein. For instance, within an embodiment of the machine having two world locking gears, the next planet locking gear may be rotatably mounted within the ring gear in a 180° off-arranged relation with respect to the first planet locking gear, about the entire 360° circumference of the ring gear. The 1st and second planet gears rotate with the band gear and also rotate about their own respective installation axes while engaging the set and output spur gear the teeth. In the lack of rotation of the ring gear, any rotational power put on the output spur equipment will push the fixed and output spur gear teeth to lock the 1st and second planet gears in place.
The primary motor input can include a sprocket in meshing engagement with a timing belt. The primary motor input may or else include a sprocket in meshing engagement with a timing chain. The primary motor input may or else 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 additional comprise a ball bearing ring positioned on the result shaft to facilitate rotation of the output spur gear. The pressure angle configuration may be from about 45 degrees to about 25 degrees. The pressure angle configuration may more ideally be from about 40 degrees to 30 degrees. The pressure angle configuration may most preferably be about 35 degrees. The parts of the gearbox may be made from metal, plastic-type material, composite, ceramic, wood, plywood, metallic 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 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 equipment units is a little tooth business lead angle of the worm and thus 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 gear unit is considered self-locking at standstill if, with worm wheel generating, beginning with standstill is not possible. This is the case with ATLANTA wheel units and gear systems when the lead position is usually <5°. A worm gear unit is considered self-locking from the working condition if the gear unit comes to a standstill whilst becoming backdriven. This is only feasible with high gear ratios and very low speeds. Shocks and vibrations can neutralize the self-locking capacity! Therefore a self-locking tooth system cannot replace a brake or reverse-stroke fasten. To avoid overstressing of the worm equipment drive because of the high kinetic energy included, you should furthermore allow for a certain running-down time after stopping the input.
