2. The apparatus system of claim 1 further comprising a second planet locking equipment rotatably mounted within said ring equipment in 180° off-set relation with respect to the first planet locking equipment, about the entire 360° circumference of the ring gear, whereby said first and second planet 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 absence of rotation of the band gear a rotational power put on said output spur equipment will push said fixed and output spur gear tooth 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 which can be driven in a forward and invert direction through an input motor 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 this kind of, these inventive equipment systems have particular program in neuro-scientific 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 should be able to wind in both a clockwise and counterclockwise direction, but not drop the strain. These inventive gear systems may also be put on move scenery, create effects, 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 enable a concise assembly. The system’s hollow through the center result spur shaft can pass wiring through to a rotating connection, and also the simple insertion of downstream tools shafts. This might be particularly useful for cable drums winding electrified cable, and turntables with electrics/electronic devices on board, for example.
The inventive gear program moreover addresses certain disadvantages of similar existing gear systems, e.g., vibration and noise issues that are unacceptable using settings (such as during theatrical performances) and burdensome maintenance through the routine lubrication of the system gears.
To address such drawbacks, briefly described, the self-locking, non-backdrivable gear program of today’s invention comprises a principal motor insight and self-lubricating gear box. The primary motor insight 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 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 band plate and seal configuration are mounted to the ring gear and seal the elements 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 ring gear, whereby the earth gear rotates with the band 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 additional 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 adjacent to the result spur equipment. The fixed spur gear has N number of gear teeth in meshing engagement with the planet gear the teeth. The fixed and result spur gears have substantially similar diameters to allow the fixed and output spur gear teeth to considerably align while engaging with the earth equipment. The fixed and output spur gear teeth each comprise a noise-dampening pressure angle configuration to angularly compliment the planet gear teeth.
In operation, rotation of the principal electric motor input causes rotation of the ring gear which causes rotation of the earth gear which in turn causes rotation of the output spur gear which causes rotation of the drive shaft. However, in the absence of rotation of the band gear, any rotational pressure put on the output spur equipment (electronic.g., via the output shaft) will drive the substantially aligned fixed and output gear the teeth to lock the planet locking gear in place.
Other aspects of the system are provided herein. For instance, within an embodiment of the system having two world locking gears, the next planet locking gear may be rotatably installed within the ring gear in a 180° off-arranged relation with respect to the first planet locking gear, about the full 360° circumference of the ring gear. The initial and second planet gears rotate with the ring gear and in addition rotate about their personal respective installation axes while engaging the set 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 pressure the fixed and result 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 or else 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 may be an O-ring or shaft seal. The gearbox may further comprise a ball bearing band positioned on the output shaft to facilitate rotation of the result spur gear. The pressure angle configuration may be from about 45 degrees to about 25 degrees. The pressure angle configuration may more ideally be from about 40 degrees to 30 degrees. The pressure angle configuration may most ideally become about 35 degrees. The parts of the gearbox may be made from metal, plastic-type, composite, ceramic, wood, self locking gearbox plywood, metal powder, or combinations thereof.
Extra objects, advantages and novel top features of the present invention will be set forth in part in the description which follows, and can in part become apparent 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 little tooth lead angle of the worm and thus an efficiency of η ≤ 0,5 with worm traveling. Consequently self-locking gear units are generally uneconomical when high performances and long operating times are needed. A worm equipment unit is known as self-locking at standstill if, with worm wheel traveling, starting from standstill is difficult. This is the case with ATLANTA wheel pieces and gear devices when the lead position is certainly <5°. A worm gear unit is known as self-locking from the operating condition if the apparatus unit comes to a standstill whilst becoming backdriven. That is only possible with high gear ratios and incredibly low speeds. Shocks and vibrations can neutralize the self-locking capacity! Therefore a self-locking tooth system cannot replace a brake or reverse-stroke fasten. In order to avoid overstressing of the worm equipment drive due to the very high kinetic energy included, you should furthermore allow for a certain running-down period after stopping the insight.
