2. The apparatus system of claim 1 further comprising a second planet locking gear rotatably mounted within stated ring gear in 180° off-set relation with respect to the first planet locking equipment, about the full 360° circumference of the ring equipment, whereby said first and second world gears rotate with stated ring gear and also rotate about their personal respective installation axes while engaging said fixed and output spur gear the teeth, and whereby in the lack of rotation of the ring gear a rotational push applied to said output spur gear will push said fixed and result spur gear the teeth to lock said 1st and second world gears in place.
With reference to the application 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 reverse direction through an input engine 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 the field of 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 should be in a position to wind in both a clockwise and counterclockwise direction, however, not drop the load. These inventive gear systems can also be put on move scenery, create results, and manipulate overhead light 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 superior to 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 complete wiring to a rotating connection, along with the simple insertion of downstream devices shafts. This might be especially 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 equipment 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 schedule lubrication of the system gears.
To address such disadvantages, briefly described, the self-locking, non-backdrivable gear program of today’s invention comprises a major motor input and self-lubricating gear package. 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, band plate and seal configuration, planet locking gear, fixed spur equipment, and output spur gear. The input ring equipment is installed 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 components within the ring equipment 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 ring gear and also rotates about its mounting axis. The output 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 equipment has N+/−X amount of gear the teeth in meshing engagement with the earth equipment. The fixed spur gear is fixedly installed around the output shaft and positioned next to the output spur equipment. The fixed spur equipment has N amount of gear the teeth in meshing engagement with the planet gear the teeth. The fixed and output spur gears have substantially similar diameters to permit the fixed and result spur gear teeth to considerably align while engaging with the earth gear. 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 engine input causes rotation of the band gear which in turn causes rotation of the earth gear which in turn causes rotation of the output spur gear which in turn causes rotation of the drive shaft. Nevertheless, in the absence of rotation of the band gear, any rotational drive put on the output spur gear (e.g., via the output shaft) will drive the substantially aligned fixed and output gear tooth to lock the earth locking gear set up.
Various other aspects of the system are provided herein. For example, within an embodiment of the machine having two world 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 planet locking equipment, about the full 360° circumference of the ring gear. The first and second planet gears rotate with the ring gear and in addition rotate about their very own respective installation axes while engaging the set and result spur gear the teeth. In the absence of rotation of the ring gear, any rotational force applied to the output spur equipment will drive the fixed and result spur gear tooth to lock the first and second planet gears in place.
The primary motor input can include a sprocket in meshing engagement with a timing belt. The primary motor input may otherwise add a sprocket in meshing engagement with a timing chain. The principal motor input may otherwise 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 output spur equipment. The pressure position 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 preferably become about 35 degrees. The elements of the gearbox may be made from metal, plastic-type, composite, ceramic, wooden, plywood, metallic powder, or combinations thereof.
Extra objects, advantages and novel features of the present invention will be established in part in the description which follows, and can in part become apparent 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 generating. Consequently self-locking gear devices are usually uneconomical when high performances and long operating times are necessary. A worm gear unit is known as self-locking at standstill if, with worm wheel driving, starting from standstill is difficult. This is actually the case with ATLANTA wheel units and gear systems when the lead position can be <5°. A worm gear unit is known as self-locking from the working condition if the gear unit comes to a standstill whilst becoming backdriven. That is only feasible with high equipment ratios and very low speeds. Shocks and vibrations can neutralize the self-locking capacity! Consequently a self-locking tooth program cannot replace a brake or reverse-stroke fasten. To avoid overstressing of the worm equipment drive due to the very high kinetic energy included, you should furthermore enable a certain running-down period after stopping the insight.
