2. The apparatus system of claim 1 further comprising a second planet locking gear rotatably mounted within stated ring gear in 180° off-arranged relation with regards to the first world locking gear, about the full 360° circumference of the ring gear, whereby said initial and second world gears rotate with stated ring gear and in addition rotate about their personal respective mounting axes while engaging said fixed and output spur gear teeth, and whereby in the lack of rotation of the ring gear a rotational push applied to said output spur equipment will power said fixed and output spur gear tooth to lock said initial and second world gears in place.
With reference to the use of the inventive gear system discussed herein, the machine provides a simple and low-cost self-lubricating gearbox which can be driven in a forward and invert direction via an input electric motor 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 this kind of, these inventive equipment systems have particular application in the field of 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 should be in a position to wind in both a clockwise and counterclockwise direction, however, not drop the strain. These inventive gear 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 produced up of friction brakes and worm drive gearboxes. The included advantages of a planetary type gear train further allow for a compact assembly. The system’s hollow through the guts result spur shaft can complete wiring through to a rotating connection, along with the basic insertion of downstream apparatus shafts. This might be especially useful for cable drums winding electrified cable, and turntables with electrics/electronic devices on board, for example.
The inventive gear system moreover addresses certain disadvantages of similar existing equipment systems, e.g., vibration and noise issues that are unacceptable using settings (such as during theatrical performances) and burdensome maintenance through the regimen lubrication of the system gears.
To address such disadvantages, briefly described, the self-locking, non-backdrivable gear system of today’s invention comprises a principal motor insight and self-lubricating gear box. The primary motor insight is 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 gear, and output spur gear. The input ring equipment is installed around the driveshaft and positioned in meshing engagement with the primary motor input. The ring plate and seal configuration are installed 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 ring gear, whereby the earth equipment rotates with the band gear and in addition rotates about its mounting axis. The result spur equipment is rotatably installed within the ring gear, in a radially inward, concentric regards to the ring equipment, and additional includes an result shaft adapted for installation to the drive shaft. The output spur equipment has N+/−X number of gear the teeth in meshing engagement with the planet gear. The fixed spur equipment is fixedly installed around the output shaft and positioned next to the result spur gear. The fixed spur gear has N amount of gear the teeth in meshing engagement with the earth gear tooth. The fixed and output spur gears have substantially similar diameters to permit the fixed and output spur gear tooth to substantially align while engaging with the earth 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 primary engine input causes rotation of the ring gear which causes rotation of the planet gear which causes rotation of the output spur gear which in turn causes rotation of the drive shaft. Nevertheless, in the lack of rotation of the ring gear, any rotational pressure put on the output spur gear (electronic.g., via the output shaft) will push the substantially aligned fixed and output gear tooth to lock the earth locking gear set up.
Other aspects of the system are provided herein. For example, in an embodiment of the system having two world locking gears, the next planet locking gear could be rotatably mounted within the ring gear in a 180° off-set 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 mounting axes while engaging the fixed and output spur gear teeth. In the absence of rotation of the band gear, any rotational force applied to the output spur equipment will power the fixed and output spur gear tooth to lock the initial 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 or else include a sprocket in meshing engagement with a timing chain. The primary motor input may otherwise 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-band or shaft seal. The gearbox may further comprise a ball bearing band 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 position 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 parts 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 set forth in part 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.

Operation and Maintenance
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 systems are usually uneconomical when high performances and lengthy operating times are necessary. A worm gear unit is known as self-locking at standstill if, with worm wheel generating, beginning with standstill is unattainable. This is the case with ATLANTA wheel units and gear systems when the lead position is definitely <5°. A worm gear unit is known as self-locking from the running condition if the gear unit involves a standstill whilst becoming backdriven. That is only feasible with high equipment 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 fasten. In order to avoid overstressing of the worm gear drive due to the high kinetic energy included, you should furthermore enable a certain running-down period after stopping the input.
