2. The gear system of claim 1 further comprising a second planet locking gear rotatably mounted within stated ring gear in 180° off-arranged relation with regards to the first planet locking gear, about the entire 360° circumference of the ring gear, whereby said 1st and second world gears self locking gearbox rotate with stated ring gear and in addition rotate about their personal respective mounting axes while engaging said fixed and output spur gear teeth, and whereby in the absence of rotation of the band gear a rotational power put on said output spur equipment will force said fixed and output spur gear teeth to lock said initial and second planet gears in place.
With reference to the use of the inventive gear system discussed herein, the machine provides a simple and low-cost self-lubricating gearbox which can be driven in a forward and invert direction through an input engine 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 built-into any rotating machinery which utilizes a winch/drum. As such, these inventive gear systems have particular program in the field of 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 must be in a position to wind in both a clockwise and counterclockwise direction, but not drop the strain. These inventive equipment systems can also be put on move scenery, create effects, 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 superior to existing configurations produced up of friction brakes and worm drive gearboxes. The integrated advantages of a planetary type equipment train further allow for a concise assembly. The system’s hollow through the center result spur shaft can complete wiring through to a rotating connection, as well as the basic insertion of downstream equipment shafts. This would be particularly useful for cable drums winding electrified cable, and turntables with electrics/electronics up to speed, for example.
The inventive gear program moreover addresses certain disadvantages of similar existing equipment systems, e.g., vibration and noise issues that are unacceptable in certain settings (such as for example during theatrical performances) and burdensome maintenance through the schedule lubrication of the system gears.
To address such disadvantages, briefly described, the self-locking, non-backdrivable gear program of today’s invention comprises a principal motor insight 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 input ring gear, ring plate and seal configuration, planet locking equipment, fixed spur equipment, and output spur gear. The input ring equipment is installed around the driveshaft and positioned in meshing engagement with the primary motor input. The band plate and seal configuration are mounted to the ring equipment and seal the parts within the ring gear so as to allow the internal self-lubrication of the gearbox through a level of lubricant.
One or more planet 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 gear is rotatably installed within the ring gear, in a radially inward, concentric relation to the ring gear, and further includes an output shaft adapted for mounting to the drive shaft. The output spur equipment has N+/−X number of gear teeth in meshing engagement with the planet gear. The fixed spur equipment is fixedly installed around the output shaft and positioned adjacent to the output spur gear. The fixed spur equipment has N amount of gear tooth in meshing engagement with the planet gear teeth. The fixed and output spur gears have considerably similar diameters to allow the fixed and result spur gear the teeth to substantially align while engaging with the planet equipment. The fixed and result spur gear teeth each comprise a noise-dampening pressure position configuration to angularly compliment the planet gear teeth.
Functioning, 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 push applied to the output spur gear (electronic.g., via the result shaft) will pressure the considerably aligned fixed and result gear teeth to lock the earth locking gear in place.
Various other aspects of the system are provided herein. For example, in an embodiment of the system having two world locking gears, the second planet locking gear may be rotatably installed within the ring gear in a 180° off-set relation with regards to the first world locking equipment, about the full 360° circumference of the ring gear. The first and second world gears rotate with the band gear and in addition rotate about their own respective installation axes while engaging the fixed and result spur gear tooth. In the absence of rotation of the band gear, any rotational force put on the output spur gear will pressure the fixed and output spur gear teeth to lock the 1st and second planet gears in place.
The principal motor input may 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 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 output shaft to facilitate rotation of the output spur equipment. The pressure angle configuration may 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 be about 35 degrees. The elements of the gearbox may be made from metal, plastic-type material, composite, ceramic, wood, plywood, metallic powder, or combinations thereof.
Extra objects, advantages and novel features of the present invention will be set forth 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 equipment units is a little tooth lead angle of the worm and thus an efficiency of η ≤ 0,5 with worm driving. Consequently self-locking gear systems are generally uneconomical when high performances and lengthy operating times are necessary. A worm gear unit is known as self-locking at standstill if, with worm wheel generating, starting from standstill is not possible. This is actually the case with ATLANTA wheel units and gear units when the lead position is <5°. A worm gear unit is considered self-locking from the operating condition if the gear unit involves 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! As a result a self-locking tooth program cannot replace a brake or reverse-stroke fasten. In order to avoid overstressing of the worm equipment drive due to the very high kinetic energy included, you should furthermore allow for a certain running-down period after stopping the insight.
