2. The gear system of claim 1 further comprising another planet locking equipment rotatably mounted within stated ring equipment in 180° off-established relation with respect to the first world locking equipment, about the entire 360° circumference of the ring gear, whereby said first and second world gears rotate with said ring gear and also rotate about their own respective mounting axes while engaging said fixed and result spur gear teeth, and whereby in the lack of rotation of the ring gear a rotational push put on said output spur equipment will pressure said fixed and output spur gear teeth to lock said 1st and second world gears in place.
With self locking gearbox 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 engine 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 equipment 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 in a position to wind in both a clockwise and counterclockwise direction, however, not drop the load. These inventive gear systems may also be put on move scenery, create effects, and manipulate overhead lighting 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 allow for a concise assembly. The system’s hollow through the guts output spur shaft can complete wiring through 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/electronics up to speed, for example.
The inventive gear system moreover addresses certain disadvantages of similar existing gear systems, e.g., vibration and noise conditions that are unacceptable using settings (such as for example during theatrical performances) and burdensome maintenance through the regimen lubrication of the system gears.
To address such drawbacks, briefly described, the self-locking, non-backdrivable gear program of today’s invention comprises a principal motor input and self-lubricating gear box. 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 equipment, and output spur equipment. The input ring gear is mounted around the driveshaft and positioned in meshing engagement with the primary motor input. The ring plate and seal configuration are mounted to the ring gear and seal the parts within the ring equipment so as to allow 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 planet equipment rotates with the ring gear and in addition rotates about its mounting axis. The output spur gear is rotatably installed within the ring gear, in a radially inward, concentric relation 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 tooth in meshing engagement with the earth gear. The fixed spur equipment is fixedly installed around the result shaft and positioned adjacent to the output spur equipment. The fixed spur gear has N quantity of gear teeth in meshing engagement with the earth gear tooth. The fixed and result spur gears have considerably similar diameters to permit the fixed and result spur gear the teeth to substantially align while engaging with the planet gear. The fixed and result spur gear the teeth each comprise a noise-dampening pressure angle configuration to angularly compliment the earth gear teeth.
In operation, rotation of the principal motor input causes rotation of the band gear which in turn causes rotation of the planet gear which causes rotation of the output spur gear which causes rotation of the drive shaft. Nevertheless, in the lack of rotation of the band gear, any rotational power put on the output spur gear (e.g., via the output shaft) will force the considerably aligned fixed and output gear tooth to lock the earth locking gear set up.
Additional aspects of the machine are provided herein. For instance, in an embodiment of the machine having two world locking gears, the next planet locking gear could be rotatably installed within the band gear in a 180° off-set relation with respect to the first world locking equipment, about the full 360° circumference of the ring gear. The first and second world gears rotate with the ring gear and also rotate about their personal respective mounting axes while engaging the set and output spur gear tooth. In the lack of rotation of the band gear, any rotational power put on the output spur equipment will drive the fixed and output spur gear the teeth to lock the first and second planet gears in place.
The primary motor input may 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 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-ring or shaft seal. The gearbox may additional comprise a ball bearing ring positioned on the output shaft to facilitate rotation of the output spur gear. The pressure position configuration could 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 ideally become about 35 degrees. The elements of the gearbox may be made from metal, plastic-type, composite, ceramic, wooden, plywood, steel powder, or combinations thereof.
Extra objects, advantages and novel top features of today’s 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 regarded 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 devices are usually 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 difficult. This is actually the case with ATLANTA wheel pieces and gear units when the lead position is certainly <5°. A worm gear unit is known as self-locking from the running condition if the gear unit comes to a standstill whilst being backdriven. That 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 system cannot replace a brake or reverse-stroke fasten. In order to avoid overstressing of the worm gear drive due to the very high kinetic energy involved, you should furthermore allow for a certain running-down period after stopping the insight.
