2. The gear system of claim 1 further comprising another planet locking gear rotatably mounted within stated ring gear in 180° off-arranged relation with respect to the first planet locking gear, about the entire 360° circumference of the ring gear, whereby said 1st and second planet gears rotate with stated ring gear and in addition rotate about their personal 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 pressure applied to said output spur equipment will power said fixed and output spur gear tooth to lock said initial and second planet gears in place.
With reference to the use of the inventive gear system discussed herein, the system provides a simple and low-cost self-lubricating gearbox that can be driven in a forward and reverse direction through an input motor 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 equipment systems have particular software 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 must be in a position to wind in both a clockwise and counterclockwise direction, however, not drop the load. These inventive gear systems can also be applied to move scenery, create effects, and manipulate overhead light and machinery during theatrical performances.
Regarding machinery that uses chain or screw jack components, a non-back driving, self-locking gearbox would offer benefits superior to existing configurations made up of friction brakes and worm drive gearboxes. The integrated benefits of a planetary type equipment train further enable a compact assembly. The system’s hollow through the guts result spur shaft can complete wiring through to a rotating connection, along with the basic insertion of downstream products shafts. This would be particularly 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 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 program lubrication of the system gears.
To address such disadvantages, briefly described, the self-locking, non-backdrivable gear program of the present invention comprises a major motor input and self-lubricating gear container. The primary motor input can be 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 gear, and output spur equipment. The input ring equipment is installed around the driveshaft and situated in meshing engagement with the principal motor input. The ring plate and seal configuration are mounted to the ring gear and seal the components within the ring equipment so as to allow the inner 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 planet equipment rotates with the ring gear and in addition rotates about its mounting axis. The result spur equipment 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 mounting to the drive shaft. The output spur gear has N+/−X amount of gear teeth in meshing engagement with the planet equipment. The fixed spur gear is fixedly installed around the output shaft and positioned adjacent to the result spur equipment. The fixed spur equipment has N quantity of gear the teeth in meshing engagement with the earth gear teeth. The fixed and result spur gears have substantially similar diameters to allow the fixed and output 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.
In operation, rotation of the primary electric motor input causes rotation of the ring gear which causes rotation of the planet gear which causes rotation of the output spur gear which in turn causes rotation of the drive shaft. Nevertheless, in the lack of rotation of the band gear, any rotational force put on the output spur equipment (electronic.g., via the output shaft) will push the considerably aligned fixed and result gear the teeth to lock the earth locking gear set up.
Other aspects of the machine are provided herein. For example, in an embodiment of the machine having two world locking gears, the second planet locking gear could be rotatably installed within the ring gear in a 180° off-arranged relation with regards to the first planet locking equipment, about the entire 360° circumference of the ring gear. The first and second planet gears rotate with the ring gear and in addition rotate about their personal respective installation axes while engaging the set and result spur gear teeth. In the lack of rotation of the band gear, any rotational drive applied to the output spur gear will power the fixed and output spur gear tooth to lock the 1st 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 or else 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 may be an O-ring or shaft seal. The gearbox may further comprise a ball bearing band positioned on the result shaft to facilitate rotation of the output spur gear. The pressure angle configuration may 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 position configuration may most ideally be about 35 degrees. The parts of the gearbox could be made from metal, plastic-type material, composite, ceramic, wood, plywood, metal powder, or combinations thereof.
Additional objects, advantages and novel features of today’s 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 considered 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 systems are generally uneconomical when high performances and lengthy operating times are needed. A worm gear unit is considered self-locking at standstill if, with worm wheel driving, starting from standstill is impossible. This is the case with ATLANTA wheel units and gear products when the lead angle is <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. This is only feasible with high equipment ratios and very low speeds. Shocks and vibrations can neutralize the self-locking capacity! Therefore a self-locking tooth program cannot replace a brake or reverse-stroke locking mechanism. In order to avoid overstressing of the worm equipment drive because of the very high kinetic energy involved, you should furthermore allow for a certain running-down time after stopping the insight.
