2. The apparatus system of claim 1 further comprising another planet locking gear rotatably mounted within stated ring equipment in 180° off-set relation with regards to the first world locking gear, about the entire 360° circumference of the ring gear, whereby said first and second planet gears rotate with said ring gear and in addition rotate about their very own respective installation axes while engaging stated fixed and result spur gear the teeth, and whereby in the absence of rotation of the ring gear a rotational pressure applied to said output spur equipment will drive said fixed and result 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 system provides a simple and low-cost self-lubricating gearbox that can be driven in a forward and invert direction via an input motor shaft, but can’t be back-driven through its output gearing. By virtue of its configuration as a band gear, the invention can be effectively built-into any rotating machinery which utilizes a winch/drum. As this kind of, these inventive gear systems have particular app in the field of overhead lifting machinery, although the invention isn’t so limited. For instance, winch machinery that utilizes a cable winding onto a cylindrical or pile-up drum must be in a position 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 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 integrated benefits of a planetary type equipment train further allow for a concise assembly. The system’s hollow through the center output spur shaft can complete wiring to a rotating connection, as well as the basic 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 drawbacks of similar existing equipment systems, e.g., vibration and noise conditions that are unacceptable in certain settings (such as during theatrical performances) and burdensome maintenance through the regimen lubrication of the system gears.
To address such drawbacks, briefly described, the self-locking, non-backdrivable gear system of the present invention comprises a major motor input and self-lubricating gear container. The primary motor input is certainly 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 gear. The input ring gear 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 gear 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 planet locking gears is rotatably mounted within the band gear, whereby the planet equipment rotates with the ring gear and in addition rotates about its own mounting axis. The result spur gear is rotatably installed within the ring equipment, in a radially inward, concentric regards to the ring equipment, and additional includes an output shaft adapted for mounting to the drive shaft. The output spur equipment has N+/−X amount of gear the teeth in meshing engagement with the earth gear. The fixed spur gear is fixedly installed around the result shaft and positioned next to the result spur gear. The fixed spur gear has N number of gear tooth in meshing engagement with the earth gear tooth. The fixed and result spur gears have considerably similar diameters to allow the fixed and output spur gear tooth to considerably align while engaging with the planet gear. The fixed and result spur gear tooth 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 in turn 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 lack of rotation of the band gear, any rotational power put on the output spur gear (e.g., via the result shaft) will force the substantially aligned fixed and result gear teeth to lock the earth locking gear in place.
Additional aspects of the machine 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-set relation with respect to the first planet locking equipment, about the entire 360° circumference of the ring gear. The first and second planet gears rotate with the ring gear and in addition rotate about their personal respective installation axes while engaging the fixed and result spur gear teeth. In the absence of rotation of the band gear, any rotational pressure put on the output spur equipment will drive the fixed and result spur gear the teeth to lock the 1st and second planet gears in place.
The principal motor input may 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 principal motor input may or else 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 further comprise a ball bearing band positioned on the result shaft to facilitate rotation of the output spur equipment. The pressure position 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 position configuration may most ideally become about 35 degrees. The elements of the gearbox may 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 partly in the description which follows, and can in part become obvious to those in the practice of the invention, when considered with the attached figures.

Self-locking property of Worm Gear Units
A precondition for the self-locking quality of gear units is a little tooth business lead angle of the worm and therefore 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 required. A worm gear unit is considered self-locking at standstill if, with worm wheel traveling, beginning with standstill is difficult. This is actually the case with ATLANTA wheel models and gear models when the lead position can be <5°. A worm gear unit is considered self-locking from the working condition if the gear unit involves a standstill whilst getting backdriven. This is only feasible 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 equipment drive because of the very high kinetic energy included, you should furthermore allow for a certain running-down time after stopping the insight.
