2. The apparatus system of claim 1 further comprising a second planet locking equipment rotatably mounted within stated ring gear in 180° self locking gearbox off-established relation with respect to the first world locking equipment, about the full 360° circumference of the ring gear, whereby said first and second world gears rotate with said ring gear and also rotate about their very own respective mounting axes while engaging stated fixed and result spur gear tooth, and whereby in the lack of rotation of the band gear a rotational force put on said output spur equipment will power said fixed and result spur gear the teeth to lock said 1st and second world 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 engine shaft, but cannot be back-driven through its output gearing. By virtue of its configuration as a ring gear, the invention can be effectively integrated into any rotating machinery which utilizes a winch/drum. As this kind of, 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 strain. These inventive equipment systems can 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 built-in advantages of a planetary type gear train further allow for a compact assembly. The system’s hollow through the guts output spur shaft can move wiring to a rotating connection, along with the simple insertion of downstream products shafts. This would be particularly useful for cable drums winding electrified cable, and turntables with electrics/consumer electronics on board, for example.
The inventive gear system moreover addresses certain drawbacks 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 regimen lubrication of the machine gears.
To address such disadvantages, briefly described, the self-locking, non-backdrivable gear program of the present invention comprises a main motor insight and self-lubricating gear package. The primary motor insight is usually 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 gear, 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 installed to the ring equipment and seal the elements within the ring gear so as to allow the internal self-lubrication of the gearbox through a volume of lubricant.
One or more planet locking gears is rotatably mounted within the ring gear, whereby the earth equipment rotates with the band gear and in addition rotates about its own mounting axis. The output spur gear is rotatably installed 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 equipment has N+/−X quantity of gear the teeth in meshing engagement with the planet gear. The fixed spur equipment is fixedly installed around the output shaft and positioned next to the output spur equipment. The fixed spur gear has N quantity of gear the teeth in meshing engagement with the planet gear the teeth. The fixed and result 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 tooth each comprise a noise-dampening pressure position configuration to angularly compliment the earth gear teeth.
Functioning, rotation of the primary engine input causes rotation of the band 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. However, in the absence of rotation of the ring gear, any rotational power put on the output spur equipment (electronic.g., via the result shaft) will push the considerably aligned fixed and result gear teeth to lock the earth locking gear set up.
Various other aspects of the machine are provided herein. For instance, within an embodiment of the system having two world locking gears, the second planet locking gear may be rotatably installed within the band gear in a 180° off-established relation with regards to the first world locking equipment, about the full 360° circumference of the ring gear. The initial and second world gears rotate with the band gear and in addition rotate about their own respective mounting axes while engaging the fixed and result spur gear tooth. In the lack of rotation of the ring gear, any rotational power applied to the output spur equipment will power the fixed and result spur gear the teeth to lock the initial and second planet gears in place.
The primary motor input may include a sprocket in meshing engagement with a timing belt. The primary motor input may otherwise add a sprocket in meshing engagement with a timing chain. The principal 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 may be an O-band 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 position configuration may more preferably be from about 40 degrees to 30 degrees. The pressure angle configuration may most preferably be about 35 degrees. The components of the gearbox could be made from metal, plastic-type, composite, ceramic, wooden, plywood, metallic powder, or combinations thereof.
Extra objects, advantages and novel top features of today’s 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.

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 therefore an efficiency of η ≤ 0,5 with worm generating. Consequently self-locking gear devices are usually 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 units and gear devices when the lead angle is certainly <5°. A worm gear unit is considered self-locking from the working condition if the apparatus unit involves a standstill whilst being backdriven. This is only possible with high gear 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. In order to avoid overstressing of the worm gear drive because of the very high kinetic energy involved, you should furthermore enable a certain running-down period after stopping the input.
