2. The gear system of claim 1 further comprising a second planet locking equipment rotatably mounted within said ring equipment in 180° off-set relation with regards to the first world locking equipment, about the entire 360° circumference of the ring gear, whereby said 1st and second world gears rotate with stated ring gear and in addition rotate about their own respective mounting axes while engaging stated fixed and result spur gear teeth, and whereby in the absence of rotation of the band gear a rotational drive put on said output spur gear will pressure said fixed and output spur gear teeth to lock said 1st and second planet gears in place.
With reference to the application of the inventive gear system discussed herein, the system offers a simple and low-cost self-lubricating gearbox that can be driven in a forward and reverse direction through an input motor shaft, but cannot be back-driven through its output gearing. By virtue of its configuration as a ring gear, the invention could be effectively integrated into any rotating machinery which utilizes a winch/drum. As this kind of, these inventive equipment systems have particular software 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 must be able to wind in both a clockwise and counterclockwise direction, however, not drop the load. These inventive gear systems may also be applied to move scenery, create results, 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 more advanced than existing configurations produced up of friction brakes and worm drive gearboxes. The built-in benefits of a planetary type gear train further enable a compact assembly. The system’s hollow through the center output spur shaft can complete wiring through to a rotating connection, and also 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 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 system gears.
To address such disadvantages, briefly described, the self-locking, non-backdrivable gear program of the present invention comprises a main 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 insight ring gear, band plate and seal configuration, planet locking gear, fixed spur gear, and output spur gear. The input ring equipment is mounted around the driveshaft and positioned in meshing engagement with the principal motor input. The band plate and seal configuration are installed to the ring gear and seal the elements within the ring equipment so as to allow the inner self-lubrication of the gearbox through a level of lubricant.
One or more world locking gears is rotatably mounted within the band gear, whereby the earth equipment rotates with the band gear and also rotates about its mounting axis. The result spur gear is rotatably mounted within the ring equipment, in a radially inward, concentric relation to the ring gear, and additional includes an output shaft adapted for installation to the drive shaft. The output spur gear has N+/−X quantity of gear the teeth in meshing engagement with the earth equipment. The fixed spur equipment is fixedly installed around the result shaft and positioned adjacent to the result spur gear. The fixed spur gear has N number of gear tooth in meshing engagement with the planet gear the teeth. The fixed and output spur gears have substantially similar diameters to allow the fixed and result spur gear tooth to substantially align while engaging with the planet equipment. The fixed and output spur gear tooth each comprise a noise-dampening pressure angle configuration to angularly compliment the planet gear teeth.
Functioning, rotation of the principal electric motor input causes rotation of the band gear which in turn causes rotation of the earth 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 drive put on the output spur equipment (electronic.g., via the output shaft) will push the substantially aligned fixed and output gear the teeth to lock the earth locking gear in place.
Various other aspects of the machine are provided herein. For example, in an embodiment of the machine 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 regards to the first world locking equipment, about the entire 360° circumference of the ring gear. The initial and second planet gears rotate with the band gear and in addition rotate about their very own respective mounting axes while engaging the fixed and result spur gear the teeth. In the absence of rotation of the ring gear, any rotational pressure applied to the output spur equipment will force the fixed and output spur gear teeth to lock the 1st and second world gears in place.
The principal motor input may include a sprocket in meshing engagement with a timing belt. The primary motor input may otherwise include a sprocket in meshing engagement with a timing chain. The primary 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-ring or shaft seal. The gearbox may further comprise a ball bearing ring 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 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 parts of the gearbox could be made from metal, plastic-type, composite, ceramic, wood, plywood, metal powder, or combinations thereof.
Additional objects, advantages and novel top 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 considered 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 driving. Consequently self-locking gear models are generally 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, starting from standstill is difficult. This is the case with ATLANTA wheel sets and gear products when the lead angle can be <5°. A worm gear unit is known as self-locking from the operating condition if the gear unit involves a standstill whilst becoming backdriven. This is only possible with high equipment 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 locking mechanism. To avoid overstressing of the worm equipment drive due to the high kinetic energy included, you should furthermore enable a certain running-down time after stopping the input.
