2. The apparatus system of claim 1 further comprising another planet locking gear rotatably mounted within said ring equipment in 180° off-set relation with regards to the first planet locking equipment, about the full 360° circumference of the ring gear, whereby said first and second world gears rotate with stated ring gear and also rotate about their own respective installation axes while engaging said fixed and output spur gear tooth, and whereby in the lack of rotation of the band gear a rotational force applied to said output spur gear will push said fixed and result spur gear teeth to lock said initial 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 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 can be effectively integrated into any rotating machinery which utilizes a winch/drum. As such, these inventive equipment systems have particular application in neuro-scientific 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 able to wind in both a clockwise and counterclockwise direction, but not drop the load. These inventive equipment systems may also be put on move scenery, create effects, and manipulate overhead lighting 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 more advanced than existing configurations made up of friction brakes and worm drive gearboxes. The integrated benefits of a planetary type equipment train further allow for a compact assembly. The system’s hollow through the center result spur shaft can pass wiring to a rotating connection, and also the simple insertion of downstream apparatus shafts. This would be especially useful for cable drums winding electrified cable, and turntables with electrics/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 in certain settings (such as for example during theatrical performances) and burdensome maintenance through the program lubrication of the machine 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, ring plate and seal configuration, planet locking equipment, fixed spur equipment, and output spur gear. The input ring equipment is mounted around the driveshaft and situated in meshing engagement with the principal motor input. The ring plate and seal configuration are installed to the ring equipment and seal the parts within the ring equipment so as to allow the internal self-lubrication of the gearbox through a volume of lubricant.
One or more world 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 mounted within the ring equipment, in a radially inward, concentric relation to the ring gear, and additional includes an output shaft adapted for mounting to the drive shaft. The output spur equipment has N+/−X amount of gear tooth 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 gear. The fixed spur equipment has N number of gear tooth in meshing engagement with the earth 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 result spur gear teeth each comprise a noise-dampening pressure angle configuration to angularly compliment the earth gear teeth.
In operation, rotation of the principal motor input causes rotation of the band gear which causes rotation of the earth gear which causes rotation of the output spur gear which in turn causes rotation of the drive shaft. However, in the absence of rotation of the ring gear, any rotational force put on the output spur equipment (electronic.g., via the result shaft) will drive the substantially aligned fixed and result gear tooth to lock the planet locking gear in place.
Additional aspects of the machine are provided herein. For instance, within an embodiment of the machine having two planet locking gears, the next planet locking gear may be rotatably mounted within the band gear in a 180° off-set up relation with respect to the first world locking equipment, about the full 360° circumference of the ring gear. The first and second world gears rotate with the band gear and also rotate about their personal respective installation axes while engaging the fixed and output spur gear the teeth. In the absence of rotation of the band gear, any rotational pressure put on the output spur gear will power the fixed and result spur gear the teeth to lock the first and second world gears in place.
The primary motor input can self locking gearbox include a sprocket in meshing engagement with a timing belt. The primary motor input may otherwise include a sprocket in meshing engagement with a timing chain. The primary motor input may or else include a sprocket in meshing engagement with a plurality of timing gears.
Each seal of the ring plate and seal configuration may be an O-ring or shaft seal. The gearbox may additional comprise a ball bearing band positioned on the output shaft to facilitate rotation of the output spur equipment. The pressure angle 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 elements of the gearbox may be made from metal, plastic-type, composite, ceramic, wooden, plywood, steel powder, or combinations thereof.
Additional objects, advantages and novel top features of today’s 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 considered with the attached figures.

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 therefore an efficiency of η ≤ 0,5 with worm driving. Consequently self-locking gear products are generally uneconomical when high performances and lengthy operating times are required. A worm gear unit is known as self-locking at standstill if, with worm wheel generating, beginning with standstill is difficult. This is the case with ATLANTA wheel units and gear models when the lead angle is <5°. A worm gear unit is known as self-locking from the running condition if the apparatus unit comes to a standstill whilst getting backdriven. This is only possible with high gear ratios and very low speeds. Shocks and vibrations can neutralize the self-locking capacity! As a result a self-locking tooth system cannot replace a brake or reverse-stroke fasten. In order to avoid overstressing of the worm gear drive due to the high kinetic energy involved, you should furthermore allow for a certain running-down time after stopping the insight.
