2. The gear system of claim 1 further comprising another planet locking equipment rotatably mounted within said ring equipment in 180° off-set relation with respect to the first planet locking equipment, about the full 360° circumference of the ring equipment, whereby said 1st and second planet gears rotate with said ring gear and in addition rotate about their own respective mounting axes while engaging said fixed and result spur gear the teeth, and whereby in the absence of rotation of the band gear a rotational force put on said output spur gear will force said fixed and output spur gear teeth to lock said 1st 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 that can be driven in a forward and reverse direction through an input engine shaft, but cannot be back-driven through its output gearing. By virtue of its configuration as a band gear, the invention could be effectively built-into any rotating machinery which utilizes a winch/drum. As such, these inventive gear systems have particular program 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 able to wind in both a clockwise and counterclockwise direction, but not drop the load. These inventive equipment systems may also be applied to move scenery, create results, 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 superior to existing configurations made up of friction brakes and worm drive gearboxes. The integrated benefits of a planetary type gear train further allow for a concise assembly. The system’s hollow through the guts output spur shaft can pass wiring through to a rotating connection, as well as the simple insertion of downstream gear shafts. This might 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 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 program lubrication of the machine gears.
To address such drawbacks, briefly described, the self-locking, non-backdrivable gear system of the present invention comprises a primary motor input and self-lubricating gear package. The primary motor input 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 principal motor input. The band plate and seal configuration are mounted to the ring equipment and seal the parts within the ring equipment so as to allow the inner self-lubrication of the gearbox through a level 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 gear is rotatably mounted within the ring equipment, in a radially inward, concentric relation to the ring gear, and further includes an output shaft adapted for mounting to the drive shaft. The output spur gear has N+/−X amount of gear tooth in meshing engagement with the earth equipment. The fixed spur equipment is fixedly mounted around the result shaft and positioned next to the output spur equipment. The fixed spur equipment has N quantity of gear tooth in meshing engagement with the planet gear teeth. The fixed and result spur gears have considerably similar diameters to allow the fixed and output spur gear teeth to substantially align while engaging with the planet gear. The fixed and result spur gear tooth each comprise a noise-dampening pressure angle configuration to angularly compliment the planet gear teeth.
Functioning, rotation of the principal motor 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 ring gear, any rotational force applied to the output spur gear (e.g., via the result shaft) will force the considerably aligned fixed and result gear teeth to lock the planet locking gear set up.
Additional aspects of the machine are provided herein. For instance, within an embodiment of the machine having two world locking gears, the second planet locking gear could be rotatably mounted within the ring gear in a 180° off-founded relation with regards to the first world locking equipment, about the entire 360° circumference of the ring gear. The first and second planet gears rotate with the ring gear and in addition rotate about their personal respective installation axes while engaging the fixed and result spur gear the teeth. In the lack of rotation of the ring gear, any rotational push put on the output spur equipment will pressure the fixed and result spur gear teeth to lock the first and second world gears in place.
The primary motor input can include a sprocket in meshing engagement with a timing belt. The primary motor input may or else include a sprocket in meshing engagement with a timing chain. The principal motor input may or else add a sprocket in meshing engagement with a plurality of timing gears.
Each seal of the ring plate and seal configuration could be an O-ring or shaft seal. The gearbox may additional comprise a ball bearing ring positioned on the output shaft to facilitate rotation of the output 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 angle configuration may most ideally become about 35 degrees. The components of the gearbox may be made from metal, plastic-type material, composite, ceramic, wood, plywood, metallic powder, or combinations thereof.
Additional objects, advantages and novel features of today’s invention will be set forth in part 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.

Operation and Maintenance
Self-locking property of Worm Gear Units
A precondition for the self-locking quality of equipment units is a small tooth lead angle of the worm and thus an efficiency of η ≤ 0,5 with worm driving. Consequently self-locking gear models are generally uneconomical when high performances and long operating times are needed. A worm equipment unit is considered self-locking at standstill if, with worm wheel traveling, starting from standstill is not possible. This is the case with ATLANTA wheel pieces and gear devices when the lead position is <5°. A worm gear unit is considered self-locking from the operating condition if the apparatus unit involves a standstill whilst being backdriven. This is only possible 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 locking mechanism. To avoid overstressing of the worm gear drive due to the very high kinetic energy involved, you should furthermore allow for a certain running-down time after stopping the input.
