2. The gear system of claim 1 further comprising another planet locking gear rotatably mounted within stated ring gear in 180° off-established relation with regards to the first planet locking gear, about the full 360° circumference of the ring equipment, whereby said initial and second world gears rotate with stated ring gear and in addition rotate about their personal respective mounting axes while engaging stated fixed and output spur gear tooth, and whereby in the absence of rotation of the band gear a rotational power put on said output spur equipment will force said fixed and result spur gear teeth 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 through an input electric 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 such, these inventive equipment systems have particular app in the field of 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 should be able to wind in both a clockwise and counterclockwise direction, however, not drop the strain. These inventive equipment systems may also be put on move scenery, create effects, and manipulate overhead light and machinery during theatrical performances.
In the case of 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 equipment train further allow for a compact assembly. The system’s hollow through the guts result spur shaft can complete wiring through to a rotating connection, along with the basic insertion of downstream gear shafts. This might be particularly useful for cable drums winding electrified cable, and turntables with electrics/electronics up to speed, for example.
The inventive gear system moreover addresses certain drawbacks of similar existing gear systems, e.g., vibration and noise issues that are unacceptable using settings (such as for example during theatrical performances) and burdensome maintenance through the regimen lubrication of the system gears.
To address such disadvantages, briefly described, the self-locking, non-backdrivable gear program of today’s invention comprises a primary motor input and self-lubricating gear container. 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 equipment, and output spur gear. The input ring equipment is mounted around the driveshaft and positioned in meshing engagement with the primary motor input. The band plate and seal configuration are mounted to the ring equipment and seal the parts within the ring gear so as to permit the inner self-lubrication of the gearbox through a volume 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 in addition rotates about its own mounting axis. The result spur gear is rotatably mounted within the ring equipment, in a radially inward, concentric relation to the ring equipment, and further includes an output shaft adapted for installation to the drive shaft. The output spur equipment has N+/−X number of gear tooth in meshing engagement with the planet equipment. The fixed spur gear is fixedly installed around the result shaft and positioned next to the output spur equipment. The fixed spur equipment has N amount of gear tooth in meshing engagement with the planet gear tooth. The fixed and output spur gears have substantially similar diameters to allow the fixed and result spur gear teeth to substantially align while engaging with the earth gear. The fixed and output spur gear teeth each comprise a noise-dampening pressure angle configuration to angularly compliment the planet gear teeth.
In operation, rotation of the principal motor input causes rotation of the band gear which in turn causes rotation of the planet gear which causes rotation of the output spur gear which in turn causes rotation of the drive shaft. However, in the absence of rotation of the band gear, any rotational push applied to the output spur gear (electronic.g., via the result shaft) will push the considerably aligned fixed and result gear tooth to lock the earth locking gear in place.
Various other aspects of the system are provided herein. For instance, in an embodiment of the system having two planet locking gears, the next planet locking gear may be rotatably installed within the ring gear in a 180° off-arranged relation with regards to the first world locking equipment, about the full 360° circumference of the ring gear. The 1st and second world gears rotate with the band gear and in addition rotate about their personal respective mounting axes while engaging the set and result spur gear tooth. In the lack of rotation of the band gear, any rotational force put on the output spur equipment will push the fixed and output spur gear tooth to lock the 1st and second planet gears in place.
The primary motor input can include a sprocket in meshing engagement with a timing belt. The principal motor input may otherwise include 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 ring plate and seal configuration could be an O-ring or shaft seal. The gearbox may additional 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 position configuration may more ideally be from about 40 degrees to 30 degrees. The pressure position configuration may most ideally be about 35 degrees. The components of the gearbox could be made from metal, plastic-type material, composite, ceramic, wood, plywood, steel powder, or combinations thereof.
Additional objects, advantages and novel top features of the present invention will be established partly in the description which follows, and can in part become apparent to those in the practice of the invention, when regarded as 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 little tooth lead angle of the worm and therefore an efficiency of η ≤ 0,5 with worm driving. Consequently self-locking gear systems 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, starting from standstill is unattainable. This is actually the case with ATLANTA wheel models and gear models when the lead position is usually <5°. A worm gear unit is known as self-locking from the working condition if the gear unit involves 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! As a result a self-locking tooth system cannot replace a brake or reverse-stroke fasten. In order to avoid overstressing of the worm equipment drive due to the very high kinetic energy involved, you should furthermore enable a certain running-down period after stopping the insight.
