2. The gear system of claim 1 further comprising another planet locking gear rotatably mounted within stated ring equipment in 180° off-arranged relation with respect to the first world locking equipment, about the full 360° circumference of the ring equipment, whereby said initial and second world gears rotate with stated ring gear and also rotate about their own respective installation axes while engaging stated 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 push said fixed and output spur gear tooth to lock said initial and second world gears in place.
With reference to the application 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 reverse direction through an input motor shaft, but can’t be back-driven through its output gearing. By virtue of its configuration as a ring gear, the invention can 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 isn’t so limited. For instance, winch machinery that utilizes a cable winding onto a cylindrical or pile-up drum must be able to wind in both a clockwise and counterclockwise direction, however, not drop the strain. These inventive equipment systems can also be put on 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 benefits of a planetary type equipment train further enable a concise assembly. The system’s hollow through the guts output spur shaft can complete wiring through to a rotating connection, and also the basic insertion of downstream devices shafts. This would be especially 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 disadvantages 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 program lubrication of the system gears.
To address such disadvantages, briefly described, the self-locking, non-backdrivable gear system of today’s invention comprises a major motor insight and self-lubricating gear box. The primary motor insight is certainly 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 equipment. The input ring gear is mounted around the driveshaft and positioned in meshing engagement with the primary motor input. The band plate and seal configuration are installed to the ring gear 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 band gear, whereby the planet gear rotates with the band gear and also rotates about its mounting axis. The output spur gear is rotatably mounted within the ring gear, in a radially inward, concentric regards to the ring equipment, and additional includes an output shaft adapted for installation to the drive shaft. The output spur equipment has N+/−X number of gear teeth in meshing engagement with the planet equipment. The fixed spur gear is fixedly installed around the result shaft and positioned adjacent to the result spur equipment. The fixed spur gear has N amount of gear teeth in meshing engagement with the planet gear teeth. The fixed and result spur gears have substantially similar diameters to permit the fixed and result spur gear 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 earth gear teeth.
In operation, rotation of the principal motor input causes rotation of the ring gear which causes rotation of the planet gear which 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 power put on the output spur gear (e.g., via the output shaft) will push the substantially aligned fixed and result gear tooth to lock the earth 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 band gear in a 180° off-set relation with respect to the first world locking gear, about the full 360° circumference of the ring gear. The first and second planet gears rotate with the ring gear and also rotate about their personal respective mounting axes while engaging the set and result spur gear teeth. In the absence of rotation of the ring gear, any rotational pressure applied to the output spur gear will push the fixed and output 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 principal motor input may otherwise add a sprocket in meshing engagement with a timing chain. The primary 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 may be an O-ring or shaft seal. The gearbox may further comprise a ball bearing ring positioned on the output shaft to facilitate rotation of the result spur gear. The pressure position configuration could be from about 45 degrees to about 25 degrees. The pressure position configuration may more ideally be from about 40 degrees to 30 degrees. The pressure angle configuration may most preferably end up being about 35 degrees. The elements of the gearbox could be made from metal, plastic material, composite, ceramic, wood, plywood, metallic powder, or combinations thereof.
Extra objects, advantages and novel features of today’s invention will be established in part 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 gear units is a little tooth business lead angle of the worm and thus an efficiency of η ≤ 0,5 with worm traveling. Consequently self-locking gear products are usually uneconomical when high performances and long operating times are needed. A worm equipment unit is considered self-locking at standstill if, with worm wheel driving, starting from standstill is difficult. This is actually the case with ATLANTA wheel sets and gear units when the lead angle is definitely <5°. A worm gear unit is considered self-locking from the working condition if the gear unit involves a standstill whilst getting backdriven. This is only possible with high equipment ratios and incredibly 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 fasten. To avoid overstressing of the worm equipment drive due to the high kinetic energy involved, you should furthermore allow for a certain running-down time after stopping the insight.
