2. The gear system of claim 1 further comprising another planet locking equipment rotatably mounted within stated ring equipment in 180° off-set relation with respect to the first world locking equipment, about the entire 360° circumference of the ring gear, whereby said first and second world gears rotate with stated ring gear and also rotate about their very own respective installation axes while engaging stated fixed and result spur gear tooth, and whereby in the lack of rotation of the band gear a rotational push put on said output spur gear will force said fixed and output spur gear the teeth to lock said first 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 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 can 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 is not so limited. For instance, 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, however, not drop the strain. 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 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 allow for a concise assembly. The system’s hollow through the guts result spur shaft can move wiring to a rotating connection, as well as the simple insertion of downstream devices 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 equipment systems, e.g., vibration and noise conditions that are unacceptable using settings (such as during theatrical performances) and burdensome maintenance through the program 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 insight 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 insight ring gear, ring plate and seal configuration, planet locking gear, fixed spur equipment, and output spur equipment. The input ring equipment is mounted around the driveshaft and situated in meshing engagement with the principal motor input. The ring plate and seal configuration are mounted to the ring equipment and seal the parts within the ring equipment so as to permit the inner self-lubrication of the gearbox through a level of lubricant.
One or more world locking gears is rotatably mounted within the band gear, whereby the earth gear rotates with the ring gear and in addition rotates about its own mounting axis. The output spur equipment is rotatably mounted within the ring equipment, in a radially inward, concentric relation to the ring equipment, and additional includes an result shaft adapted for installation to the drive shaft. The output spur gear has N+/−X amount of gear the teeth in meshing engagement with the planet equipment. The fixed spur gear is fixedly mounted around the output shaft and positioned adjacent to the result spur equipment. The fixed spur gear has N number of gear tooth 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 considerably align while engaging with the planet equipment. The fixed and result spur gear the teeth each comprise a noise-dampening pressure position configuration to angularly compliment the earth gear teeth.
Functioning, rotation of the principal electric motor input causes rotation of the ring 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 lack of rotation of the ring gear, any rotational drive applied to the output spur gear (e.g., via the result shaft) will force the substantially aligned fixed and result gear teeth to lock the planet locking gear set up.
Various other aspects of the machine are provided herein. For example, within an embodiment of the system having two world locking gears, the next planet locking gear could be rotatably installed within the band gear in a 180° off-set relation with respect to the first world locking equipment, about the entire 360° circumference of the ring gear. The first and second planet gears rotate with the band gear and in addition rotate about their personal respective installation axes while engaging the fixed and result spur gear the teeth. In the absence of rotation of the ring gear, any rotational push put on 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 can include a sprocket in meshing engagement with a timing belt. The primary motor input may otherwise 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 could be an O-ring or shaft seal. The gearbox may additional comprise a ball bearing band positioned on the result shaft to facilitate rotation of the output spur gear. The pressure angle 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 be about 35 degrees. The components of the gearbox could be made from metal, plastic, composite, ceramic, wood, plywood, metallic powder, or combinations thereof.
Extra objects, advantages and novel features of the present invention will be set forth partly in the description which follows, and will in part become obvious to those in the practice of the invention, when regarded 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 generating. Consequently self-locking gear units 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 generating, starting from standstill is impossible. This is actually the case with ATLANTA wheel units and gear devices when the lead position is usually <5°. A worm gear unit is considered self-locking from the working condition if the apparatus unit comes to a standstill whilst becoming backdriven. This is only possible with high equipment ratios and incredibly low speeds. Shocks and vibrations can neutralize the self-locking capacity! Therefore a self-locking tooth program cannot replace a brake or reverse-stroke fasten. To avoid overstressing of the worm equipment drive due to the high kinetic energy involved, you should furthermore enable a certain running-down time after stopping the insight.
