2. The gear system of claim 1 further comprising another planet locking equipment rotatably mounted within stated ring gear in 180° off-set relation with respect to the first planet locking gear, about the full 360° circumference of the ring gear, whereby said first and second world gears rotate with said ring gear and also rotate about their personal respective mounting axes while engaging said fixed and output spur gear tooth, and whereby in the absence of rotation of the band gear a rotational power applied to said output spur gear will push said fixed and output spur gear teeth to lock said 1st and second world gears in place.
With reference to the application of the inventive gear system discussed herein, the system provides a simple and low-cost self-lubricating gearbox that can be driven in a forward and invert direction via an input electric 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 such, these inventive equipment systems have particular software in the field of overhead lifting machinery, although the invention is not 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, however, not drop the strain. These inventive equipment systems can also be applied to move scenery, create effects, and manipulate overhead lighting 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 made up of friction brakes and worm drive gearboxes. The built-in benefits of a planetary type equipment train further enable a concise assembly. The system’s hollow through the guts output spur shaft can pass wiring through to a rotating connection, along with the basic insertion of downstream tools shafts. This might be especially useful for cable drums winding electrified cable, and turntables with electrics/electronics on board, for example.
The inventive gear system moreover addresses certain disadvantages of similar existing gear 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 schedule lubrication of the system gears.
To address such disadvantages, briefly described, the self-locking, non-backdrivable gear system of the present invention comprises a principal motor insight and self-lubricating gear package. The primary motor insight can be 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 equipment, fixed spur equipment, and output spur equipment. The input ring gear is mounted around the driveshaft and situated in meshing engagement with the primary motor input. The ring plate and seal configuration are installed to the ring gear and seal the parts within the ring gear so as to allow the inner self-lubrication of the gearbox through a level of lubricant.
One or more world locking gears is rotatably mounted within the ring gear, whereby the earth equipment rotates with the ring gear and in addition rotates about its own mounting axis. The output spur gear is rotatably mounted within the ring gear, in a radially inward, concentric regards to the ring gear, and further includes an output shaft adapted for installation to the drive shaft. The output spur gear has N+/−X amount of gear teeth in meshing engagement with the earth gear. The fixed spur gear is fixedly mounted around the output shaft and positioned next to the result spur equipment. The fixed spur equipment has N amount of gear tooth in meshing engagement with the earth gear tooth. The fixed and output spur gears have substantially similar diameters to allow the fixed and result spur gear the teeth to considerably align while engaging with the earth gear. The fixed and result spur gear tooth each comprise a noise-dampening pressure angle configuration to angularly compliment the earth gear teeth.
Functioning, rotation of the primary electric motor input causes rotation of the band gear which causes rotation of the planet 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 pressure applied to the output spur equipment (electronic.g., via the result shaft) will push the considerably aligned fixed and output gear the teeth to lock the earth locking gear set up.
Other aspects of the system are provided herein. For instance, within an embodiment of the system having two planet locking gears, the second planet locking gear may be rotatably installed within the ring gear in a 180° off-arranged relation with respect to the first planet locking equipment, about the entire 360° circumference of the ring gear. The first and second planet gears rotate with the band gear and also rotate about their personal respective installation axes while engaging the fixed and output spur gear teeth. In the absence of rotation of the ring gear, any rotational pressure put on the output spur equipment will drive the fixed and result spur gear the teeth to lock the initial and second planet gears in place.
The primary motor input may 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 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-ring or shaft seal. The gearbox may further comprise a ball bearing ring positioned on the output shaft to facilitate rotation of the result spur gear. The pressure position 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 components of the gearbox could be made from metal, plastic-type material, composite, ceramic, wood, plywood, steel powder, or combinations thereof.
Additional objects, advantages and novel features of the present invention will be set forth partly in the description which follows, and will in part become apparent to those in the practice of the invention, when regarded as 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 thus an efficiency of η ≤ 0,5 with worm driving. Consequently self-locking gear devices are usually uneconomical when high performances and long operating times are required. A worm gear unit is considered self-locking at standstill if, with worm wheel traveling, beginning with standstill is unattainable. This is actually the case with ATLANTA wheel pieces and gear devices when the lead position is usually <5°. A worm gear unit is known as self-locking from the running condition if the gear unit comes to a standstill whilst becoming backdriven. This is only feasible with high equipment ratios and incredibly low speeds. Shocks and vibrations can neutralize the self-locking capacity! For that reason a self-locking tooth program cannot replace a brake or reverse-stroke locking mechanism. In order to avoid overstressing of the worm gear drive because of the high kinetic energy involved, you should furthermore allow for a certain running-down time after stopping the insight.
