2. The gear system of claim 1 further comprising a second planet locking equipment rotatably mounted within said ring gear in 180° off-arranged relation with respect to the first planet locking gear, about the entire 360° self locking gearbox circumference of the ring gear, whereby said initial and second world gears rotate with said ring gear and also rotate about their personal respective mounting axes while engaging said fixed and output spur gear tooth, and whereby in the absence of rotation of the ring gear a rotational force applied to said output spur equipment will power said fixed and result spur gear tooth 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 that can be driven in a forward and reverse direction through an input engine shaft, but cannot 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 equipment systems have particular application in the field of overhead lifting machinery, although the invention is not 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, but not drop the load. These inventive equipment systems can also be put on move scenery, create results, and manipulate overhead lighting 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 produced up of friction brakes and worm drive gearboxes. The built-in advantages of a planetary type equipment train further enable a compact assembly. The system’s hollow through the center output spur shaft can move wiring through to a rotating connection, as well as the simple insertion of downstream tools shafts. This might be particularly useful for cable drums winding electrified cable, and turntables with electrics/electronic devices 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 for example during theatrical performances) and burdensome maintenance through the program lubrication of the machine gears.
To address such disadvantages, briefly described, the self-locking, non-backdrivable gear program of today’s invention comprises a main motor input and self-lubricating gear package. 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, ring plate and seal configuration, planet locking equipment, fixed spur gear, and output spur gear. The input ring equipment is installed around the driveshaft and situated in meshing engagement with the primary motor input. The band plate and seal configuration are installed to the ring gear and seal the parts within the ring gear so as to allow the internal self-lubrication of the gearbox through a volume of lubricant.
One or more planet locking gears is rotatably mounted within the band gear, whereby the planet gear rotates with the ring gear and in addition rotates about its own mounting axis. The result spur gear is rotatably installed within the ring gear, 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 the teeth in meshing engagement with the earth equipment. The fixed spur equipment is fixedly mounted around the output shaft and positioned adjacent to the result spur equipment. The fixed spur equipment has N amount of gear teeth in meshing engagement with the earth gear tooth. The fixed and output spur gears have considerably similar diameters to permit the fixed and output spur gear the teeth to considerably align while engaging with the planet gear. The fixed and result spur gear the teeth each comprise a noise-dampening pressure position configuration to angularly compliment the planet gear teeth.
Functioning, rotation of the primary engine 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 power applied to the output spur gear (electronic.g., via the result shaft) will push the substantially aligned fixed and output gear tooth to lock the earth locking gear in place.
Additional aspects of the system are provided herein. For example, within an embodiment of the machine having two planet locking gears, the second planet locking gear could be rotatably mounted within the ring gear in a 180° off-founded relation with respect to the first planet locking gear, about the full 360° circumference of the ring gear. The first and second planet gears rotate with the band gear and in addition rotate about their very own respective installation axes while engaging the set and result spur gear teeth. In the absence of rotation of the ring gear, any rotational force put on the output spur equipment will power the fixed and output spur gear teeth to lock the first and second planet gears in place.
The primary motor input may include a sprocket in meshing engagement with a timing belt. The primary 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 ring plate and seal configuration may be an O-band or shaft seal. The gearbox may further comprise a ball bearing band positioned on the output shaft to facilitate rotation of the result spur equipment. The pressure angle 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 preferably become about 35 degrees. The components of the gearbox may be made from metal, plastic-type, composite, ceramic, wood, plywood, steel powder, or combinations thereof.
Additional objects, advantages and novel features of the present invention will be established partly in the description which follows, and will in part become apparent to those in the practice of the invention, when regarded as with the attached figures.

Self-locking property of Worm Gear Units
A precondition for the self-locking quality of gear units is a little tooth business lead angle of the worm and therefore an efficiency of η ≤ 0,5 with worm traveling. Consequently self-locking gear systems are usually uneconomical when high performances and lengthy operating times are required. A worm equipment unit is considered self-locking at standstill if, with worm wheel driving, starting from standstill is not possible. This is the case with ATLANTA wheel pieces and gear devices when the lead position is certainly <5°. A worm gear unit is known as self-locking from the running condition if the gear unit comes to a standstill whilst getting backdriven. That is only possible with high gear ratios and very low speeds. Shocks and vibrations can neutralize the self-locking capacity! As a result a self-locking tooth program cannot replace a brake or reverse-stroke fasten. To avoid overstressing of the worm gear drive due to the very high kinetic energy included, you should furthermore enable a certain running-down period after stopping the insight.
