2. The gear self locking gearbox system of claim 1 further comprising a second planet locking equipment rotatably mounted within said ring gear in 180° off-arranged relation with respect to the first planet locking gear, about the entire 360° circumference of the ring equipment, whereby said 1st and second world gears rotate with stated ring gear and also rotate about their very own respective mounting axes while engaging stated fixed and output spur gear tooth, and whereby in the absence of rotation of the ring gear a rotational pressure put on said output spur gear will power said fixed and output spur gear tooth to lock said initial and second world gears in place.
With reference to the use of the inventive gear system discussed herein, the system offers a simple and low-cost self-lubricating gearbox which can be driven in a forward and invert direction via 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 integrated into any rotating machinery which utilizes a winch/drum. As this kind of, these inventive equipment systems have particular application 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 must be able to wind in both a clockwise and counterclockwise direction, but not drop the load. These inventive gear systems may also be put on 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 superior to existing configurations made up of friction brakes and worm drive gearboxes. The integrated advantages of a planetary type gear train further enable a concise assembly. The system’s hollow through the guts output spur shaft can move wiring to a rotating connection, along with the basic insertion of downstream devices shafts. This would be particularly useful for cable drums winding electrified cable, and turntables with electrics/electronics on board, for example.
The inventive gear program moreover addresses certain disadvantages of similar existing gear 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 routine lubrication of the system gears.
To address such disadvantages, briefly described, the self-locking, non-backdrivable gear system of the present invention comprises a main 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 equipment, fixed spur gear, and output spur equipment. The input ring equipment is installed around the driveshaft and situated in meshing engagement with the primary motor input. The band plate and seal configuration are mounted to the ring equipment and seal the components within the ring equipment so as to permit 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 equipment rotates with the band gear and in addition rotates about its 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 quantity of gear teeth in meshing engagement with the earth equipment. The fixed spur equipment is fixedly mounted around the result shaft and positioned next to the result spur gear. The fixed spur equipment has N amount of gear tooth in meshing engagement with the planet gear the teeth. The fixed and output spur gears have substantially similar diameters to permit the fixed and output spur gear the teeth to substantially align while engaging with the earth gear. 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 primary electric motor input causes rotation of the ring 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 ring gear, any rotational push put on the output spur equipment (e.g., via the output shaft) will drive the substantially aligned fixed and result gear tooth to lock the planet locking gear set up.
Other aspects of the system are provided herein. For example, in an embodiment of the machine having two world locking gears, the next planet locking gear may be rotatably installed within the band gear in a 180° off-arranged relation with respect to the first planet locking equipment, about the full 360° circumference of the ring gear. The initial and second world gears rotate with the ring gear and in addition rotate about their very own respective mounting axes while engaging the set and result spur gear teeth. In the absence of rotation of the band gear, any rotational force put on the output spur equipment will force the fixed and result spur gear tooth 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 principal motor input may otherwise add a sprocket in meshing engagement with a timing chain. The primary motor input may or else 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 ring positioned on the output shaft to facilitate rotation of the result spur equipment. The pressure angle configuration could 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, wooden, plywood, steel powder, or combinations thereof.
Extra objects, advantages and novel features of the present invention will be set forth in part in the description which follows, and will in part become obvious to those in the practice of the invention, when considered 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 business lead angle of the worm and thus an efficiency of η ≤ 0,5 with worm traveling. Consequently self-locking gear products are usually uneconomical when high performances and lengthy operating times are required. A worm equipment unit is known as self-locking at standstill if, with worm wheel generating, beginning with standstill is difficult. This is the case with ATLANTA wheel pieces and gear systems when the lead angle is definitely <5°. A worm gear unit is known as self-locking from the running condition if the apparatus unit comes to a standstill whilst becoming backdriven. This is only possible with high gear ratios and very low speeds. Shocks and vibrations can neutralize the self-locking capacity! Consequently a self-locking tooth system cannot replace a brake or reverse-stroke fasten. In order to avoid overstressing of the worm gear drive because of the very high kinetic energy involved, you should furthermore allow for a certain running-down period after stopping the input.
