2. The apparatus system of claim 1 further comprising another planet locking equipment rotatably mounted within stated ring equipment in 180° off-set relation with regards to the first world locking gear, about the full 360° circumference of the ring equipment, whereby said first and second planet gears rotate with stated ring gear and also rotate about their very own respective mounting axes while engaging stated fixed and result spur gear the teeth, and whereby in the lack of rotation of the band gear a rotational drive put on said output spur gear will drive said fixed and output spur gear teeth to lock said first and second planet gears in place.
With reference to the use of the inventive gear system discussed herein, the machine provides a simple and low-cost self-lubricating gearbox that can be driven in a forward and reverse direction via an input engine 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 such, these inventive equipment systems have particular software 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 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 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 more advanced than existing configurations produced up of friction brakes and worm drive gearboxes. The integrated advantages of a planetary type gear train further allow for a compact assembly. The system’s hollow through the guts output spur shaft can pass wiring to a rotating connection, as well as the simple insertion of downstream equipment 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 system moreover addresses certain disadvantages of similar existing equipment systems, e.g., vibration and noise conditions that are unacceptable using settings (such as for example during theatrical performances) and burdensome maintenance through the schedule lubrication of the system gears.
To address such drawbacks, briefly described, the self-locking, non-backdrivable gear program of today’s invention comprises a primary motor input and self-lubricating gear package. The primary motor insight is definitely 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 equipment, fixed spur equipment, and output spur gear. The input ring gear is installed around the driveshaft and situated in meshing engagement with the principal motor input. The band plate and seal configuration are mounted to the ring equipment and seal the components within the ring gear so as to permit the inner self-lubrication of the gearbox through a volume of lubricant.
One or more planet locking gears is rotatably mounted within the ring gear, whereby the planet gear rotates with the ring gear and also rotates about its mounting axis. The output spur equipment is rotatably installed within the ring equipment, in a radially inward, concentric relation to the ring gear, and further includes an output shaft adapted for installation to the drive shaft. The output spur equipment has N+/−X amount of gear tooth in meshing engagement with the planet gear. The fixed spur equipment is fixedly mounted around the output shaft and positioned adjacent to the result spur gear. The fixed spur gear has N number of gear the teeth in meshing engagement with the planet gear the teeth. The fixed and result spur gears have substantially similar diameters to permit the fixed and output spur gear the teeth to substantially align while engaging with the earth gear. The fixed and output spur gear teeth each comprise a noise-dampening pressure position configuration to angularly compliment the planet gear teeth.
Functioning, rotation of the primary electric motor input causes rotation of the band gear which in turn causes rotation of the earth gear which causes rotation of the output spur gear which causes rotation of the drive shaft. Nevertheless, in the lack of rotation of the band gear, any rotational pressure applied to the output spur equipment (electronic.g., via the output shaft) will power the considerably aligned fixed and result gear the teeth to lock the planet locking gear set up.
Additional aspects of the machine are provided herein. For instance, in an embodiment of the system having two planet locking gears, the next planet locking gear may be rotatably mounted within the ring gear in a 180° off-set relation with regards to the first planet locking equipment, about the full 360° circumference of the ring gear. The first and second world gears rotate with the ring gear and also 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 band gear, any rotational force applied to the output spur equipment will drive the fixed and output spur gear tooth to lock the initial and second world gears in place.
The primary 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 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 could be an O-band or shaft seal. The gearbox may additional comprise a ball bearing band positioned on the output shaft to facilitate rotation of the output spur equipment. 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 angle configuration may most ideally be 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 top features of today’s invention will be established partly in the description which follows, and will in part become obvious to those in the practice of the invention, when regarded with the attached figures.

Self-locking property of Worm Gear Units
A precondition for the self-locking quality of equipment units is a small tooth business lead angle of the worm and thus an efficiency of η ≤ 0,5 with worm driving. Consequently self-locking gear units are generally uneconomical when high performances and lengthy operating times are necessary. A worm gear unit is considered self-locking at standstill if, with worm wheel traveling, beginning with standstill is not possible. This is the case with ATLANTA wheel units and gear systems when the lead angle is definitely <5°. A worm gear unit is known as self-locking from the operating condition if the gear unit involves a standstill whilst getting 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. To avoid overstressing of the worm equipment drive because of the high kinetic energy included, you should furthermore allow for a certain running-down period after stopping the input.
