2. The gear system of claim 1 further comprising a second planet locking gear rotatably mounted within said ring equipment in 180° off-set relation with respect to the first world locking equipment, about the full 360° circumference of the ring equipment, whereby said initial and second planet gears rotate with stated ring gear and also rotate about their very own respective installation axes while engaging said fixed and output spur gear teeth, and whereby in the absence of rotation of the ring gear a rotational pressure put on said output spur gear will power said fixed and result spur gear the teeth to lock said initial and second planet 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 which can be driven in a forward and reverse 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 could be effectively integrated into any rotating machinery which utilizes a winch/drum. As this kind of, these inventive equipment systems have particular software 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 should be able to wind in both a clockwise and counterclockwise direction, but not drop the load. These inventive equipment systems may also be applied to move scenery, create effects, 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 superior to existing configurations produced up of friction brakes and worm drive gearboxes. The integrated benefits 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, and also the simple insertion of downstream tools shafts. This would be particularly useful for cable drums winding electrified cable, and turntables with electrics/consumer electronics on board, for example.
The inventive gear program moreover addresses certain disadvantages of similar existing gear systems, e.g., vibration and noise conditions that are unacceptable in certain settings (such as during theatrical performances) and burdensome maintenance through the regimen 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 input and self-lubricating gear package. The primary motor input 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 gear, fixed spur equipment, and output spur gear. The input ring equipment 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 equipment and seal the elements within the ring gear so as to allow the internal 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 earth equipment rotates with the ring gear and also rotates about its mounting axis. The output spur gear is rotatably mounted within the ring equipment, in a radially inward, concentric regards to the ring equipment, and additional includes an output shaft adapted for mounting to the drive shaft. The output spur gear has N+/−X number of gear the teeth in meshing engagement with the earth gear. The fixed spur equipment is fixedly installed around the output shaft and positioned next to the result spur equipment. The fixed spur gear has N quantity of gear the teeth in meshing engagement with the planet gear teeth. The fixed and result spur gears have substantially similar diameters to permit the fixed and output spur gear tooth to substantially align while engaging with the earth 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 motor input causes rotation of the ring gear which causes rotation of the earth gear which in turn causes rotation of the output spur gear which causes rotation of the drive shaft. However, in the absence of rotation of the band gear, any rotational power applied to the output spur gear (electronic.g., via the output shaft) will pressure the considerably aligned fixed and output gear the teeth to lock the earth locking gear set up.
Various other aspects of the machine are provided herein. For instance, within an embodiment of the machine having two planet locking gears, the next planet locking gear could be rotatably mounted within the band gear in a 180° off-set relation with regards to the first planet locking equipment, about the full 360° circumference of the ring gear. The 1st and second world gears rotate with the band gear and also rotate about their very own respective installation axes while engaging the fixed and output spur gear the teeth. In the lack of rotation of the band gear, any rotational power applied to the output spur gear will power the fixed and output spur gear tooth to lock the first and second world gears in place.
The principal motor input may include a sprocket in meshing engagement with a timing belt. The principal motor input may or else add a sprocket in meshing engagement with a timing chain. The primary motor input may otherwise 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-band 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 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 angle configuration may most ideally be about 35 degrees. The parts of the gearbox could be made from metal, plastic-type material, composite, ceramic, wooden, plywood, metal powder, or combinations thereof.
Additional objects, advantages and novel features of the present invention will be set forth partly 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 equipment units is a small tooth business lead angle of the worm and therefore an efficiency of η ≤ 0,5 with worm generating. Consequently self-locking gear systems are generally uneconomical when high performances and long operating times are necessary. A worm equipment unit is known as self-locking at standstill if, with worm wheel driving, starting from standstill is extremely hard. This is actually the case with ATLANTA wheel units and gear products when the lead angle is certainly <5°. A worm gear unit is known as self-locking from the running condition if the gear unit involves a standstill whilst becoming backdriven. That is only possible with high gear ratios and very low speeds. Shocks and vibrations can neutralize the self-locking capacity! For that reason a self-locking tooth system cannot replace a brake or reverse-stroke locking mechanism. In order to avoid overstressing of the worm gear drive because of the very high kinetic energy included, you should furthermore allow for a certain running-down time after stopping the insight.
