2. The apparatus system of claim 1 further comprising a second planet locking gear rotatably mounted within said ring gear in 180° off-set relation with respect to the first planet locking equipment, about the full 360° circumference of the ring gear, whereby said first and second world gears rotate with said ring gear and in addition rotate about their very own respective mounting axes while engaging stated fixed and output spur gear the teeth, and whereby in the lack of rotation of the ring gear a rotational pressure applied to said output spur gear will push said fixed and output spur gear the teeth to lock said first and second world gears in place.
With reference to the use 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 electric motor shaft, but can’t be back-driven through its output gearing. By virtue of its configuration as a ring 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 program 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 able to wind in both a clockwise and counterclockwise direction, however, not drop the load. These inventive equipment systems may also be applied to 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 gear train further enable a compact assembly. The system’s hollow through the center result spur shaft can complete wiring through to a rotating connection, and also the simple insertion of downstream products shafts. This might be especially 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 equipment systems, e.g., vibration and noise issues that are unacceptable using settings (such as for example during theatrical performances) and burdensome maintenance through the routine lubrication of the machine gears.
To address such drawbacks, briefly described, the self-locking, non-backdrivable gear system of today’s invention comprises a main motor insight and self-lubricating gear package. The primary motor insight can be 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 gear, fixed spur equipment, 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 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 ring gear, whereby the planet equipment rotates with the band gear and in addition 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 further includes an result shaft adapted for installation to the drive shaft. The output spur equipment has N+/−X amount of gear teeth in meshing engagement with the planet gear. The fixed spur gear is fixedly installed around the result shaft and positioned adjacent to the result spur equipment. The fixed spur gear has N amount of gear tooth in meshing engagement with the earth gear tooth. The fixed and output spur gears have considerably similar diameters to allow the fixed and output spur gear the teeth to substantially align while engaging with the earth gear. The fixed and result spur gear teeth each comprise a noise-dampening pressure position configuration to angularly compliment the earth gear teeth.
Functioning, rotation of the primary electric motor input causes rotation of the ring gear which in turn causes rotation of the planet gear which 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 force applied to the output spur gear (electronic.g., via the result shaft) will pressure the substantially aligned fixed and result gear teeth to lock the planet locking gear set up.
Additional aspects of the machine are provided herein. For instance, within an embodiment of the machine having two world locking gears, the next planet locking gear could be rotatably installed within the ring gear in a 180° off-arranged relation with regards to the first planet locking equipment, about the entire 360° circumference of the ring gear. The initial and second planet gears rotate with the band gear and also rotate about their personal respective installation axes while engaging the set and output spur gear the teeth. In the lack of rotation of the ring gear, any rotational pressure put on the output spur equipment will power the fixed and result spur gear teeth to lock the 1st and second world gears in place.
The primary motor input can include a sprocket in meshing engagement with a timing belt. The primary motor input may or else add a sprocket in meshing engagement with a timing chain. The primary motor input may or else add a sprocket in meshing engagement with a plurality of timing gears.
Each seal of the band plate and seal configuration may be an O-ring or shaft seal. The gearbox may additional comprise a ball bearing ring positioned on the output 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 preferably be from about 40 degrees to 30 degrees. The pressure angle configuration may most ideally be about 35 degrees. The elements of the gearbox may be made from metal, plastic-type, composite, ceramic, wood, 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 will in part become apparent 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 small tooth lead angle of the worm and thus an efficiency of η ≤ 0,5 with worm generating. Consequently self-locking gear models are usually uneconomical when high performances and lengthy operating times are necessary. A worm equipment unit is considered self-locking at standstill if, with worm wheel driving, beginning with standstill is extremely hard. This is actually the case with ATLANTA wheel sets and gear units when the lead position is certainly <5°. A worm gear unit is considered self-locking from the operating condition if the gear unit involves a standstill whilst getting backdriven. This is only possible with high equipment ratios and very 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 locking mechanism. In order to avoid overstressing of the worm equipment drive due to the very high kinetic energy involved, you should furthermore allow for a certain running-down period after stopping the input.
