2. The apparatus system of claim 1 further comprising a second planet locking equipment rotatably mounted within stated ring equipment in 180° off-arranged relation with respect to the first world locking equipment, about the full 360° circumference of the ring equipment, whereby said first and second planet gears rotate with said ring gear and also rotate about their personal respective installation axes while engaging said fixed and output spur gear teeth, and whereby in the lack of rotation of the ring gear a rotational drive applied to said output spur equipment will drive said fixed and output spur gear tooth to lock said first and second world 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 invert direction through an input engine shaft, but cannot 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 program in the field of 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 must be in a position to wind in both a clockwise and counterclockwise direction, however, not drop the load. These inventive equipment systems can also be applied to 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 included benefits of a planetary type equipment train further enable a compact assembly. The system’s hollow through the guts result spur shaft can complete wiring through to a rotating connection, and also the basic insertion of downstream devices shafts. This would be particularly useful for cable drums winding electrified cable, and turntables with electrics/consumer electronics up to speed, for example.
The inventive gear system moreover addresses certain drawbacks of similar existing gear systems, e.g., vibration and noise conditions that are unacceptable using settings (such as for example during theatrical performances) and burdensome maintenance through the program lubrication of the system gears.
To address such disadvantages, briefly described, the self-locking, non-backdrivable gear program of today’s invention comprises a primary motor insight and self-lubricating gear container. 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 gear, and output spur gear. The input ring gear is mounted around the driveshaft and situated in meshing engagement with the principal motor input. The band plate and seal configuration are mounted to the ring equipment and seal the elements within the ring gear so as to allow the internal 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 gear rotates with the band gear and also rotates about its own mounting axis. The result spur gear is rotatably mounted within the ring equipment, in a radially inward, concentric regards to the ring gear, and additional includes an result shaft adapted for mounting to the drive shaft. The output spur equipment has N+/−X quantity of gear teeth in meshing engagement with the earth gear. The fixed spur equipment is fixedly installed around the output shaft and positioned next to the output spur gear. The fixed spur gear has N number of gear the teeth in meshing engagement with the planet gear tooth. The fixed and result spur gears have substantially similar diameters to permit the fixed and result spur gear teeth to considerably align while engaging with the planet equipment. The fixed and output spur gear the teeth each comprise a noise-dampening pressure position configuration to angularly compliment the earth gear teeth.
In operation, rotation of the principal electric motor input causes rotation of the band gear which in turn causes rotation of the planet gear which causes rotation of the output spur gear which causes rotation of the drive shaft. However, in the lack of rotation of the band gear, any rotational force applied to the output spur equipment (e.g., via the output shaft) will pressure the substantially aligned fixed and output gear teeth to lock the earth locking gear in place.
Various other aspects of the machine are provided herein. For example, in an embodiment of the machine having two planet locking gears, the second planet locking gear could be rotatably installed 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 very own respective mounting axes while engaging the set and output spur gear tooth. In the absence of rotation of the band gear, any rotational pressure put on the output spur equipment will power the fixed and result spur gear the teeth to lock the initial and second planet gears in place.
The principal motor input can include a sprocket in meshing engagement with a timing belt. The principal 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 could be an O-ring or shaft seal. The gearbox may further comprise a ball bearing band positioned on the result 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 angle configuration may more preferably be from about 40 degrees to 30 degrees. The pressure position configuration may most ideally become about 35 degrees. The parts of the gearbox could be made from metal, plastic material, composite, ceramic, wooden, plywood, metallic powder, or combinations thereof.
Extra objects, advantages and novel features of the present invention will be established 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.

Self-locking property of Worm Gear Units
A precondition for the self-locking quality of gear units is a little tooth business lead angle of the worm and thus an efficiency of η ≤ 0,5 with worm traveling. Consequently self-locking gear models are usually 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 traveling, starting from standstill is not possible. This is the case with ATLANTA wheel models and gear devices when the lead position can be <5°. A worm gear unit is known as self-locking from the working condition if the gear unit involves a standstill whilst being backdriven. This is only feasible with high equipment 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 locking mechanism. 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 time after stopping the insight.
