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 planet locking equipment, about the full 360° circumference of the ring equipment, whereby said 1st and second world gears rotate with stated ring gear and in addition rotate about their very own respective installation axes while engaging said fixed and output spur gear tooth, and whereby in the lack of rotation of the band gear a rotational force applied to said output spur gear will drive said fixed and result spur gear tooth to lock said initial 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 which can be driven in a forward and invert 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 built-into any rotating machinery which utilizes a winch/drum. As such, these inventive gear systems have particular program in neuro-scientific 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, but not drop the load. These inventive equipment systems may also be put on move scenery, create results, and manipulate overhead lighting 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 built-in benefits of a planetary type gear train further enable a compact assembly. The system’s hollow through the center result spur shaft can pass wiring to a rotating connection, as well as the basic insertion of downstream apparatus shafts. This might be especially useful for cable drums winding electrified cable, and turntables with electrics/consumer electronics up to speed, for example.
The inventive gear program moreover addresses certain drawbacks of similar existing equipment systems, e.g., vibration and noise issues that are unacceptable in certain settings (such as 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 system of the present invention comprises a main motor insight and self-lubricating gear package. The primary motor insight 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 gear, fixed spur equipment, and output spur gear. The input ring equipment is installed around the driveshaft and situated in meshing engagement with the principal motor input. The band plate and seal configuration are installed to the ring equipment and seal the parts within the ring gear so as to permit the internal 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 gear rotates with the band gear and also rotates about its own mounting axis. The result spur equipment is rotatably mounted within the ring equipment, in a radially inward, concentric regards to the ring gear, and further includes an result shaft adapted for installation to the drive shaft. The output spur equipment has N+/−X quantity of gear the teeth in meshing engagement with the planet equipment. The fixed spur equipment is fixedly installed around the result shaft and positioned next to the result spur gear. The fixed spur equipment has N amount of gear the teeth in meshing engagement with the planet gear teeth. The fixed and result spur gears have considerably similar diameters to allow the fixed and result spur gear tooth to considerably align while engaging with the earth gear. The fixed and output spur gear tooth each comprise a noise-dampening pressure position configuration to angularly compliment the earth gear teeth.
Functioning, rotation of the primary engine input causes rotation of the band gear which causes rotation of the earth gear which in turn causes rotation of the output spur gear which causes rotation of the drive shaft. However, in the absence of rotation of the ring gear, any rotational force applied to the output spur equipment (electronic.g., via the result shaft) will push the considerably aligned fixed and result gear teeth to lock the planet locking gear in place.
Other aspects of the machine are provided herein. For instance, within an embodiment of the system having two planet locking gears, the second planet locking gear may be rotatably mounted within the ring gear in a 180° off-founded relation with regards to the first world locking gear, 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 own respective installation axes while engaging the fixed and result spur gear the teeth. In the absence of rotation of the band gear, any rotational pressure applied to the output spur gear will pressure the fixed and result spur gear teeth to lock the initial 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 otherwise add a sprocket in meshing engagement with a timing chain. The principal 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 could be an O-band or shaft seal. The gearbox may further comprise a ball bearing band positioned on the result shaft to facilitate rotation of the result spur equipment. The pressure angle configuration may 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 position configuration may most preferably be about 35 degrees. The components of the gearbox could be made from metal, plastic, composite, ceramic, wood, plywood, metallic powder, or combinations thereof.
Additional objects, advantages and novel top features of the present invention will be established in part in the description which follows, and will in part become obvious 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 small tooth business lead angle of the worm and therefore an efficiency of η ≤ 0,5 with worm traveling. Consequently self-locking gear products are generally uneconomical when high performances and long operating times are required. A worm equipment unit is known as self-locking at standstill if, with worm wheel traveling, beginning with standstill is extremely hard. This is the case with ATLANTA wheel units and gear products when the lead position is definitely <5°. A worm gear unit is considered self-locking from the working condition if the apparatus unit involves a standstill whilst becoming 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 system cannot replace a brake or reverse-stroke fasten. To avoid overstressing of the worm gear drive because of the high kinetic energy included, you should furthermore enable a certain running-down time after stopping the input.
