2. The apparatus system of claim 1 further comprising a second planet locking gear rotatably mounted within said ring equipment in 180° off-arranged relation with respect to the first planet locking equipment, about the entire 360° circumference of the ring gear, whereby said initial and second planet gears rotate with said ring gear and in addition rotate about their very own respective mounting axes while engaging stated fixed and result spur gear tooth, and whereby in the lack of rotation of the band gear a rotational power put on said output spur gear will force said fixed and result spur gear teeth to lock said first and second world gears in place.
With reference to the application of the inventive gear system discussed herein, the machine provides a simple and low-cost self-lubricating gearbox that can be driven in a forward and invert direction via an input engine shaft, but cannot be back-driven through its output gearing. By virtue of its configuration as a band gear, the invention could be effectively integrated into any rotating machinery which utilizes a winch/drum. As this kind of, these inventive gear systems have particular application in the field of overhead lifting machinery, although the invention is not 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 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 made up of friction brakes and worm drive gearboxes. The integrated advantages of a planetary type equipment train further enable a concise assembly. The system’s hollow through the guts result spur shaft can complete wiring to a rotating connection, as well as the basic insertion of downstream tools shafts. This might 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 gear systems, e.g., vibration and noise issues that are unacceptable using settings (such as for example during theatrical performances) and burdensome maintenance through the routine lubrication of the machine gears.
To address such disadvantages, briefly described, the self-locking, non-backdrivable gear system of the present invention comprises a major motor insight and self-lubricating gear container. The primary motor input is certainly 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 equipment. The input ring equipment is installed 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 components within the ring equipment so as to permit the internal self-lubrication of the gearbox through a volume of lubricant.
One or more planet locking gears is rotatably mounted within the ring gear, whereby the earth gear rotates with the ring gear and also rotates about its own mounting axis. The result spur equipment is rotatably mounted within the ring gear, in a radially inward, concentric regards to the ring gear, and further includes an result shaft adapted for mounting to the drive shaft. The output spur gear 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 next to the result spur equipment. The fixed spur gear has N number of gear teeth in meshing engagement with the planet gear tooth. The fixed and result spur gears have considerably similar diameters to allow the fixed and output spur gear teeth to considerably align while engaging with the planet gear. The fixed and output spur gear tooth each comprise a noise-dampening pressure angle configuration to angularly compliment the planet gear teeth.
Functioning, rotation of the principal motor input causes rotation of the ring gear which in turn causes rotation of the planet gear which in turn causes rotation of the output spur gear which causes rotation of the drive shaft. Nevertheless, in the absence of rotation of the band gear, any rotational force applied to the output spur gear (e.g., via the output shaft) will push the substantially aligned fixed and output gear tooth to lock the earth locking gear set up.
Other aspects of the system are provided herein. For instance, within an embodiment of the machine having two planet locking gears, the second planet locking gear could be rotatably installed within the ring gear in a 180° off-founded relation with regards to the first world locking equipment, 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 own respective mounting axes while engaging the fixed and result spur gear teeth. In the absence of rotation of the ring gear, any rotational pressure applied to the output spur gear will power the fixed and output spur gear the teeth to lock the initial 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 otherwise include a sprocket in meshing engagement with a timing chain. The principal 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 may be an O-band or shaft seal. The gearbox may additional comprise a ball bearing ring positioned on the result shaft to facilitate rotation of the result spur equipment. The pressure position configuration may be from about 45 degrees to about 25 degrees. The pressure position configuration may more preferably be from about 40 degrees to 30 degrees. The pressure angle configuration may most preferably become about 35 degrees. The parts of the gearbox could be made from metal, plastic-type, composite, ceramic, wooden, plywood, steel 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 can in part become apparent 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 lead angle of the worm and therefore an efficiency of η ≤ 0,5 with worm driving. Consequently self-locking gear models are usually uneconomical when high performances and long operating times are needed. A worm gear unit is considered self-locking at standstill if, with worm wheel generating, beginning with standstill is extremely hard. This is the case with ATLANTA wheel pieces and gear products when the lead angle can be <5°. A worm gear unit is considered self-locking from the running condition if the gear unit comes to 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! As a result a self-locking tooth system cannot replace a brake or reverse-stroke locking mechanism. In order to avoid overstressing of the worm equipment drive due to the very high kinetic energy involved, you should furthermore allow for a certain running-down period after stopping the insight.
