2. The gear system of claim 1 further comprising a second planet locking equipment rotatably mounted within stated ring gear in 180° off-arranged relation with respect to the first planet locking gear, about the full 360° circumference of the ring equipment, whereby said 1st and second planet gears rotate with said ring gear and in addition rotate about their personal respective mounting axes while engaging stated fixed and result spur gear teeth, and whereby in the absence of rotation of the ring gear a rotational pressure put on said output spur gear will force said fixed and output spur gear tooth to lock said first 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 that can be driven in a forward and reverse direction via an input engine shaft, but can’t 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 gear systems have particular program in the field of 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 in a position to wind in both a clockwise and counterclockwise direction, however, not drop the strain. These inventive gear systems may also be applied to 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 included 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 through to a rotating connection, as well as the basic insertion of downstream products shafts. This might be especially useful for cable drums winding electrified cable, and turntables with electrics/consumer 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 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 insight and self-lubricating gear box. The primary motor input is usually adapted for rotation of the gearbox about the axis of a drive shaft. The gearbox comprises an insight ring gear, band plate and seal configuration, planet locking gear, fixed spur gear, and output spur equipment. The input ring gear 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 components within the ring gear 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 earth gear rotates with the ring gear and also rotates about its mounting axis. The output spur equipment is rotatably installed within the ring gear, in a radially inward, concentric regards to the ring equipment, and further includes an result shaft adapted for mounting to the drive shaft. The output spur gear has N+/−X number of gear the teeth in meshing engagement with the planet equipment. The fixed spur equipment is fixedly mounted around the output shaft and positioned next to the output spur gear. The fixed spur gear has N quantity of gear the teeth in meshing engagement with the planet gear the teeth. The fixed and output spur gears have substantially similar diameters to allow the fixed and output spur gear tooth to substantially align while engaging with the planet gear. The fixed and output spur gear tooth each comprise a noise-dampening pressure position configuration to angularly compliment the planet gear teeth.
In operation, rotation of the primary engine input causes rotation of the ring gear which in turn 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 lack of rotation of the band gear, any rotational power applied to the output spur gear (e.g., via the output shaft) will pressure the considerably aligned fixed and output gear teeth to lock the earth locking gear in place.
Other aspects of the system are provided herein. For example, in an embodiment of the system having two planet locking gears, the second planet locking gear could be rotatably installed within the ring gear in a 180° off-set relation with respect to the first planet locking gear, about the full 360° circumference of the ring gear. The 1st and second planet 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 tooth. In the lack of rotation of the ring gear, any rotational drive applied to the output spur gear will pressure the fixed and output spur gear 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 or else add a sprocket in meshing engagement with a timing chain. The principal motor input may otherwise include a sprocket in meshing engagement with a plurality of timing gears.
Each seal of the band plate and seal configuration could be an O-band or shaft seal. The gearbox may further comprise a ball bearing band positioned on the result shaft to facilitate rotation of the result spur gear. The pressure position 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 position configuration may most preferably become about 35 degrees. The parts of the gearbox could be made from metal, plastic, composite, ceramic, wood, plywood, metal 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 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 small tooth lead angle of the worm and thus an efficiency of η ≤ 0,5 with worm traveling. Consequently self-locking gear models are usually uneconomical when high performances and long operating times are needed. A worm equipment unit is considered self-locking at standstill if, with worm wheel driving, beginning with standstill is not possible. This is actually the case with ATLANTA wheel pieces and gear products when the lead position is definitely <5°. A worm gear unit is considered self-locking from the operating condition if the gear unit comes to a standstill whilst becoming backdriven. That is only feasible with high equipment 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 locking mechanism. To avoid overstressing of the worm equipment drive because of the very high kinetic energy included, you should furthermore enable a certain running-down period after stopping the input.
