2. The apparatus system of claim 1 further comprising a second planet locking equipment rotatably mounted within stated ring equipment in 180° off-set relation with respect to the first planet locking gear, about the entire 360° circumference of the ring equipment, 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 result spur gear the teeth, and whereby in the absence of rotation of the ring gear a rotational force put on said output spur gear will drive said fixed and result spur gear tooth to lock said first 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 engine shaft, but can’t be back-driven through its output gearing. By virtue of its configuration as a band gear, the invention can be effectively built-into any rotating machinery which utilizes a winch/drum. As this kind of, these inventive equipment systems have particular app 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 in a position to wind in both a clockwise and counterclockwise direction, but not drop the load. These inventive equipment systems can 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 made 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 pass wiring through to a rotating connection, as well as the basic insertion of downstream tools 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 conditions that are unacceptable using settings (such as during theatrical performances) and burdensome maintenance through the schedule lubrication of the machine gears.
To address such disadvantages, briefly described, the self-locking, non-backdrivable gear system of today’s invention comprises a primary motor input and self-lubricating gear container. The primary motor insight is 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 mounted around the driveshaft and situated 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 volume of lubricant.
One or more world locking gears is rotatably mounted within the band gear, whereby the earth equipment rotates with the ring gear and in addition rotates about its mounting axis. The output spur gear is rotatably installed 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 the teeth in meshing engagement with the planet equipment. The fixed spur equipment is fixedly mounted around the result shaft and positioned next to the result spur equipment. The fixed spur equipment has N quantity of gear teeth in meshing engagement with the earth gear teeth. The fixed and output spur gears have considerably similar diameters to permit the fixed and result spur gear the teeth to considerably align while engaging with the earth gear. The fixed and result spur gear the teeth each comprise a noise-dampening pressure position configuration to angularly compliment the earth gear teeth.
In operation, rotation of the primary engine input causes rotation of the band gear which causes rotation of the earth gear which 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 put on the output spur equipment (e.g., via the output shaft) will pressure the substantially aligned fixed and output gear tooth to lock the earth locking gear set up.
Other 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 may be rotatably mounted within the band gear in a 180° off-set up relation with respect to the first planet locking gear, about the full 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 set and result spur gear the teeth. In the absence of rotation of the ring gear, any rotational drive applied to the output spur equipment will push the fixed and output spur gear teeth to lock the initial and second planet gears in place.
The primary motor input can 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 add 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 output 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 angle configuration may more ideally be from about 40 degrees to 30 degrees. The pressure angle configuration may most preferably become about 35 degrees. The components of the gearbox could be made from metal, plastic-type, composite, ceramic, wooden, plywood, steel powder, or combinations thereof.
Extra objects, advantages and novel features of today’s invention will be established partly in the description which follows, and can 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 equipment 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 units are generally uneconomical when high performances and long operating times are required. A worm equipment unit is considered self-locking at standstill if, with worm wheel traveling, starting from standstill is not possible. This is actually the case with ATLANTA wheel pieces and gear devices when the lead position can be <5°. A worm gear unit is known as self-locking from the working condition if the gear unit comes to a standstill whilst getting backdriven. That is only feasible with high gear ratios and very low speeds. Shocks and vibrations can neutralize the self-locking capacity! For that reason a self-locking tooth program cannot replace a brake or reverse-stroke locking mechanism. To avoid overstressing of the worm equipment drive due to the high kinetic energy involved, you should furthermore enable a certain running-down period after stopping the insight.
