2. The apparatus system of claim 1 further comprising a second planet locking gear rotatably mounted within stated ring gear in 180° off-arranged relation with respect to the first planet locking equipment, about the full 360° circumference of the ring equipment, whereby said 1st and second world gears rotate with stated ring gear and also rotate about their personal respective mounting axes while engaging stated fixed and result spur gear teeth, and whereby in the absence of rotation of the band gear a rotational force put on said output spur gear will push said fixed and output spur gear the teeth to lock said first and second world gears in place.
With reference to the application 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 invert direction via an input electric motor 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 gear systems have particular program 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 should be in a position to wind in both a clockwise and counterclockwise direction, but not drop the strain. These inventive gear systems may 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 integrated advantages of a planetary type equipment train further allow for a compact assembly. The system’s hollow through the guts output spur shaft can complete wiring to a rotating connection, as well as the basic insertion of downstream products shafts. This might be particularly useful for cable drums winding electrified cable, and turntables with electrics/electronic devices up to speed, for example.
The inventive gear program moreover addresses certain drawbacks of similar existing equipment systems, e.g., vibration and noise issues that are unacceptable using settings (such as during theatrical performances) and burdensome maintenance through the program lubrication of the system gears.
To address such drawbacks, briefly described, the self-locking, non-backdrivable gear program of the present invention comprises a primary motor input and self-lubricating gear package. The primary motor insight 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 gear, and output spur gear. The input ring equipment is mounted around the driveshaft and positioned 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 permit the internal self-lubrication of the gearbox through a level of lubricant.
One or more world locking gears is rotatably mounted within the ring gear, whereby the earth equipment rotates with the band gear and also rotates about its mounting axis. The output spur gear is rotatably mounted within the ring equipment, in a radially inward, concentric relation to the ring gear, and additional includes an output shaft adapted for mounting to the drive shaft. The output spur gear has N+/−X amount of gear the teeth in meshing engagement with the earth gear. The fixed spur gear is fixedly installed around the output shaft and positioned next to the output spur equipment. The fixed spur gear has N number of gear teeth in meshing engagement with the earth gear the teeth. The fixed and output spur gears have substantially similar diameters to permit the fixed and output spur gear tooth to considerably align while engaging with the earth equipment. The fixed and output spur gear teeth each comprise a noise-dampening pressure angle configuration to angularly compliment the earth gear teeth.
Functioning, rotation of the primary electric motor input causes rotation of the ring gear which in turn 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 ring gear, any rotational pressure applied to the output spur gear (e.g., via the output shaft) will drive the substantially aligned fixed and result gear teeth to lock the earth locking gear in place.
Other aspects of the system are provided herein. For example, within an embodiment of the system having two world 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 planet locking equipment, about the full 360° circumference of the ring gear. The first and second planet gears rotate with the band gear and also rotate about their very own respective installation axes while engaging the fixed and result spur gear teeth. In the lack of rotation of the ring gear, any rotational push applied to the output spur gear will force the fixed and result spur gear tooth to lock the initial and second planet gears in place.
The principal motor input can include a sprocket in meshing engagement with a timing belt. The principal 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 may 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 result spur gear. The pressure position configuration could 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 position configuration may most ideally become about 35 degrees. The parts of the gearbox may be made from metal, plastic material, composite, ceramic, wooden, plywood, metal powder, or combinations thereof.
Additional objects, advantages and novel features of today’s invention will be established in part in the description which follows, and can 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 small tooth business lead angle of the worm and thus an efficiency of η ≤ 0,5 with worm generating. Consequently self-locking gear units are usually uneconomical when high performances and long operating times are required. A worm gear unit is considered self-locking at standstill if, with worm wheel generating, beginning with standstill is unattainable. This is actually the case with ATLANTA wheel pieces and gear devices when the lead position can be <5°. A worm gear unit is considered self-locking from the operating condition if the gear unit involves a standstill whilst getting backdriven. That 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 system 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 allow for a certain running-down period after stopping the insight.
