2. The apparatus system of claim 1 further comprising another planet locking equipment rotatably mounted within said ring gear in 180° off-established relation with regards to the first world locking gear, about the entire 360° circumference of the ring gear, whereby said initial and second planet gears rotate with stated ring gear and in addition rotate about their own respective mounting axes while engaging said fixed and result spur gear tooth, and whereby in the lack of rotation of the band gear a rotational power applied to said output spur equipment will power said fixed and result spur gear tooth to lock said 1st 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 through an input motor shaft, but can’t 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 app in neuro-scientific 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, but not drop the load. These inventive equipment systems may also be put on 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 produced 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 center output spur shaft can pass wiring through to a rotating connection, and also the basic insertion of downstream equipment shafts. This would be particularly useful for cable drums winding electrified cable, and turntables with electrics/electronic devices on board, for example.
The inventive gear system moreover addresses certain drawbacks 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 program lubrication of the machine gears.
To address such disadvantages, briefly described, the self-locking, non-backdrivable gear program of today’s invention comprises a principal motor insight and self-lubricating gear package. The primary motor insight is usually adapted for rotation of the gearbox about the axis of a drive shaft. The gearbox comprises an insight ring gear, band plate and seal configuration, planet locking equipment, fixed spur equipment, and output spur equipment. The input ring equipment is mounted around the driveshaft and situated 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 internal self-lubrication of the gearbox through a volume of lubricant.
One or more world locking gears is rotatably mounted within the band gear, whereby the earth gear rotates with the band gear and also rotates about its mounting axis. The result spur equipment is rotatably installed within the ring equipment, in a radially inward, concentric regards to the ring gear, and additional includes an result shaft adapted for installation to the drive shaft. The output spur gear has N+/−X number of gear tooth in meshing engagement with the earth gear. The fixed spur equipment is fixedly mounted around the result shaft and positioned next to the output spur gear. The fixed spur gear has N amount of gear the teeth in meshing engagement with the earth gear teeth. The fixed and result spur gears have considerably similar diameters to allow the fixed and result spur gear tooth to substantially align while engaging with the planet gear. The fixed and output spur gear teeth each comprise a noise-dampening pressure angle configuration to angularly compliment the planet gear teeth.
Functioning, rotation of the primary engine 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 power applied to the output spur gear (e.g., via the result shaft) will force the substantially aligned fixed and output gear tooth to lock the planet locking gear in place.
Other aspects of the machine are provided herein. For example, within an embodiment of the machine having two planet locking gears, the next planet locking gear may be rotatably installed within the ring gear in a 180° off-founded relation with respect to the first planet locking gear, about the full 360° circumference of the ring gear. The 1st and second world gears rotate with the ring gear and in addition rotate about their personal respective installation axes while engaging the set and output spur gear tooth. In the lack of rotation of the band gear, any rotational power applied to the output spur gear will power the fixed and result spur gear teeth to lock the initial and second world gears in place.
The principal motor input can include a sprocket in meshing engagement with a timing belt. The primary motor input may or else add a sprocket in meshing engagement with a timing chain. The principal 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-band or shaft seal. The gearbox may further comprise a ball bearing ring positioned on the output shaft to facilitate rotation of the result spur equipment. 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 preferably become about 35 degrees. The elements of the gearbox may be made from metal, plastic material, composite, ceramic, wooden, plywood, steel powder, or combinations thereof.
Additional objects, advantages and novel top features of the present invention will be set forth partly in the description which follows, and can in part become apparent to those in the practice of the invention, when regarded as 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 therefore an efficiency of η ≤ 0,5 with worm traveling. Consequently self-locking gear devices are usually uneconomical when high performances and lengthy operating times are needed. A worm gear unit is known as self-locking at standstill if, with worm wheel traveling, starting from standstill is impossible. This is actually 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 working condition if the apparatus unit involves 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! For that reason a self-locking tooth system cannot replace a brake or reverse-stroke fasten. In order to avoid overstressing of the worm equipment drive because of the high kinetic energy included, you should furthermore enable a certain running-down period after stopping the insight.
