2. The apparatus system of claim 1 further comprising a second planet locking gear rotatably mounted within said ring equipment in 180° off-arranged relation with regards to the first world locking gear, about the entire 360° circumference of the ring equipment, whereby said 1st and second world gears rotate with said ring gear and also rotate about their very own respective mounting axes while engaging said fixed and result spur gear teeth, and whereby in the lack of rotation of the ring gear a rotational power put on said output spur equipment will push said fixed and output spur gear the teeth to lock said initial and second planet gears in place.
With reference to the use 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 reverse direction via an input electric motor shaft, but cannot 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 equipment systems have particular software 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, however, not drop the strain. These inventive equipment systems can also be put on move scenery, create results, and manipulate overhead light 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 produced up of friction brakes and worm drive gearboxes. The built-in self locking gearbox advantages of a planetary type equipment train further enable a concise assembly. The system’s hollow through the center result spur shaft can complete wiring through to a rotating connection, and also the basic insertion of downstream equipment shafts. This might be especially 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 equipment systems, e.g., vibration and noise issues that are unacceptable using settings (such as during theatrical performances) and burdensome maintenance through the schedule lubrication of the machine gears.
To address such disadvantages, briefly described, the self-locking, non-backdrivable gear program of today’s invention comprises a major motor input and self-lubricating gear container. 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, ring plate and seal configuration, planet locking equipment, fixed spur equipment, and output spur gear. 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 gear and seal the parts within the ring equipment so as to permit the internal 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 also rotates about its own mounting axis. The output spur gear is rotatably mounted within the ring equipment, in a radially inward, concentric regards to the ring equipment, and additional includes an result shaft adapted for installation to the drive shaft. The output spur gear has N+/−X number of gear teeth in meshing engagement with the planet equipment. The fixed spur equipment is fixedly installed around the output shaft and positioned adjacent to the output spur gear. The fixed spur gear has N number of gear tooth in meshing engagement with the earth gear the teeth. The fixed and output spur gears have considerably similar diameters to permit the fixed and output spur gear the teeth to considerably align while engaging with the planet equipment. The fixed and output spur gear the teeth each comprise a noise-dampening pressure position configuration to angularly compliment the planet gear teeth.
Functioning, rotation of the primary motor input causes rotation of the ring gear which causes rotation of the earth gear which 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 force applied to the output spur equipment (electronic.g., via the result shaft) will force the substantially aligned fixed and result gear tooth to lock the planet locking gear set up.
Various other aspects of the machine are provided herein. For instance, in an embodiment of the system having two world locking gears, the second planet locking gear could be rotatably mounted within the ring gear in a 180° off-established relation with regards to the first planet locking gear, about the full 360° circumference of the ring gear. The 1st and second world gears rotate with the ring gear and in addition rotate about their own respective mounting axes while engaging the set and output spur gear tooth. 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 principal motor input can include a sprocket in meshing engagement with a timing belt. The principal motor input may or else add a sprocket in meshing engagement with a timing chain. The principal motor input may otherwise 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 result shaft to facilitate rotation of the result spur equipment. 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 ideally end up being about 35 degrees. The components of the gearbox may be made from metal, plastic material, composite, ceramic, wooden, plywood, steel 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 obvious 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 equipment units is a little tooth business lead angle of the worm and thus an efficiency of η ≤ 0,5 with worm generating. Consequently self-locking gear products are generally uneconomical when high performances and lengthy operating times are required. A worm gear unit is considered self-locking at standstill if, with worm wheel traveling, beginning with standstill is extremely hard. This is the case with ATLANTA wheel sets and gear models when the lead position 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. That is only possible 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 fasten. To avoid overstressing of the worm equipment drive because of the very high kinetic energy included, you should furthermore allow for a certain running-down period after stopping the insight.
