2. The apparatus system of claim 1 further comprising a second planet locking equipment rotatably mounted within stated ring gear in 180° off-established relation with respect to the first world locking gear, about the full 360° circumference of the ring gear, whereby said first and second planet gears rotate with said 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 ring gear a rotational pressure put on said output spur equipment will drive said fixed and output spur gear teeth to lock said 1st 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 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 integrated into any rotating machinery which utilizes a winch/drum. As such, these inventive gear systems have particular app in the field of overhead lifting machinery, although the invention is not so limited. For example, winch machinery that utilizes a cable winding onto a cylindrical or pile-up drum must be in a position to wind in both a clockwise and counterclockwise direction, but not drop the strain. These inventive gear systems can 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 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 result spur shaft can move wiring through to a rotating connection, along with the simple insertion of downstream products shafts. This would be particularly useful for cable drums winding electrified cable, and turntables with electrics/electronic devices up to speed, for example.
The inventive gear system moreover addresses certain drawbacks of similar existing equipment systems, e.g., vibration and noise conditions that are unacceptable in certain settings (such as for example during theatrical performances) and burdensome maintenance through the routine lubrication of the system gears.
To address such drawbacks, briefly described, the self-locking, non-backdrivable gear system of the present invention comprises a major motor input and self-lubricating gear box. The primary motor input is definitely 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 principal motor input. The band plate and seal configuration are installed to the ring equipment 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 planet locking gears is rotatably mounted within the ring gear, whereby the earth equipment rotates with the band gear and in addition rotates about its own mounting axis. The output spur gear is rotatably installed within the ring equipment, in a radially inward, concentric regards to the ring gear, and additional includes an result shaft adapted for installation to the drive shaft. The output spur gear has N+/−X quantity of gear the teeth in meshing engagement with the earth gear. The fixed spur equipment is fixedly mounted around the output shaft and positioned next to the output spur equipment. The fixed spur equipment has N quantity of gear teeth in meshing engagement with the earth 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 planet gear. The fixed and output spur gear tooth each comprise a noise-dampening pressure position configuration to angularly compliment the planet gear teeth.
In operation, rotation of the primary electric motor input causes rotation of the band gear which causes rotation of the planet gear which in turn causes rotation of the output spur gear which causes rotation of the drive shaft. However, in the lack of rotation of the ring gear, any rotational drive applied to the output spur gear (e.g., via the output shaft) will power the considerably aligned fixed and result 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 system having two world locking gears, the next planet locking gear may be rotatably installed within the band gear in a 180° off-set relation with regards 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 own respective mounting axes while engaging the set and output spur gear tooth. In the absence of rotation of the band gear, any rotational drive applied to the output spur equipment will force the fixed and output spur gear tooth 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 principal motor input may otherwise 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-ring or shaft seal. The gearbox may additional comprise a ball bearing band positioned on the result shaft to facilitate rotation of the output spur gear. The pressure position configuration could 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 angle 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 features of the present invention will be set forth in part in the description which follows, and will in part become obvious to those in the practice of the invention, when considered with the attached figures.

Operation and Maintenance
Self-locking property of Worm Gear Units
A precondition for the self-locking quality of equipment units is a little tooth business lead angle of the worm and thus an efficiency of η ≤ 0,5 with worm driving. Consequently self-locking gear devices are usually uneconomical when high performances and lengthy operating times are needed. A worm equipment unit is considered self-locking at standstill if, with worm wheel generating, beginning with standstill is not possible. This is the case with ATLANTA wheel units and gear devices when the lead angle is <5°. A worm gear unit is considered self-locking from the working condition if the gear unit comes to a standstill whilst becoming backdriven. This is only feasible with high gear ratios and incredibly low speeds. Shocks and vibrations can neutralize the self-locking capacity! Consequently a self-locking tooth program cannot replace a brake or reverse-stroke fasten. To avoid overstressing of the worm gear drive because of the high kinetic energy involved, you should furthermore enable a certain running-down period after stopping the insight.
