2. The apparatus system of claim 1 further comprising another planet locking gear rotatably mounted within said ring gear in 180° off-established relation with regards to the first world locking equipment, about the entire 360° circumference of the ring equipment, whereby said 1st and second world gears rotate with said ring gear and in addition rotate about their personal respective installation axes while engaging stated fixed and result spur gear the teeth, and whereby in the absence of rotation of the band gear a rotational pressure applied to said output spur equipment will power said fixed and output 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 machine offers a simple and low-cost self-lubricating gearbox which can be driven in a forward and reverse direction via an input 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 this kind of, these inventive equipment systems have particular application 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 must be able to wind in both a clockwise and counterclockwise direction, but not drop the strain. These inventive gear systems may also be applied to 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 superior to 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 guts output spur shaft can complete wiring to a rotating connection, along with the basic 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 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 routine lubrication of the system gears.
To address such disadvantages, briefly described, the self-locking, non-backdrivable gear system of today’s invention comprises a major motor input and self-lubricating gear container. The primary motor input is definitely 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 gear, fixed spur equipment, and output spur equipment. The input ring gear is installed around the driveshaft and situated in meshing engagement with the primary motor input. The band plate and seal configuration are installed to the ring gear and seal the elements within the ring gear so as to permit the inner 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 ring gear and in addition rotates about its own mounting axis. The result spur equipment is rotatably mounted within the ring equipment, in a radially inward, concentric regards to the ring gear, and additional includes an output shaft adapted for installation to the drive shaft. The output spur gear has N+/−X amount of gear tooth in meshing engagement with the earth gear. The fixed spur equipment is fixedly installed around the result shaft and positioned next to the output spur gear. The fixed spur gear has N quantity of gear tooth in meshing engagement with the earth gear teeth. The fixed and output spur gears have considerably similar diameters to allow the fixed and output spur gear tooth to substantially align while engaging with the planet gear. The fixed and result spur gear teeth each comprise a noise-dampening pressure position configuration to angularly compliment the earth gear teeth.
In operation, rotation of the primary electric motor input causes rotation of the ring gear which causes rotation of the earth gear which in turn 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 push put on the output spur equipment (e.g., via the result shaft) will push the considerably aligned fixed and output gear the teeth to lock the planet locking gear in place.
Additional aspects of the machine are provided herein. For example, within an embodiment of the machine having two world locking gears, the next planet locking gear could be rotatably installed within the ring gear in a 180° off-set relation with regards 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 in addition rotate about their personal respective mounting axes while engaging the fixed and result spur gear tooth. In the absence of rotation of the ring gear, any rotational push put on the output spur gear will push the fixed and result spur gear the teeth to lock the 1st and second planet gears in place.
The principal motor input may include a sprocket in meshing engagement with a timing belt. The principal motor input may otherwise add 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 result spur equipment. The pressure position 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 position configuration may most preferably end up being about 35 degrees. The components of the gearbox could be made from metal, plastic, composite, ceramic, wooden, plywood, steel powder, or combinations thereof.
Extra objects, advantages and novel top 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 considered 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 generating. Consequently self-locking gear products are generally uneconomical when high performances and long operating times are necessary. A worm equipment unit is known as self-locking at standstill if, with worm wheel traveling, beginning with standstill is difficult. This is actually the case with ATLANTA wheel pieces and gear devices when the lead position is definitely <5°. A worm gear unit is known as self-locking from the running condition if the apparatus unit involves a standstill whilst getting backdriven. This is only possible with high gear ratios and incredibly low speeds. Shocks and vibrations can neutralize the self-locking capacity! Consequently a self-locking tooth system cannot replace a brake or reverse-stroke locking mechanism. To avoid overstressing of the worm equipment drive because of the very high kinetic energy involved, you should furthermore enable a certain running-down period after stopping the insight.
