2. The apparatus system of claim 1 further comprising another planet locking gear rotatably mounted within stated ring equipment in 180° off-set relation with regards to the first planet locking equipment, about the entire 360° circumference of the ring gear, whereby said initial and second planet gears rotate with stated ring gear and also rotate about their own respective installation axes while engaging said fixed and result spur gear tooth, and whereby in the absence of rotation of the band gear a rotational drive applied to said output spur equipment will pressure said fixed and result 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 system offers a simple and low-cost self-lubricating gearbox which can be driven in a forward and invert direction via an input motor shaft, but cannot be back-driven through its output gearing. By virtue of its configuration as a ring gear, the invention can be effectively integrated into any rotating machinery which utilizes a winch/drum. As this kind of, these inventive gear systems have particular application in neuro-scientific 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 must be able to wind in both a clockwise and counterclockwise direction, but not drop the load. These inventive equipment systems may also be put on move scenery, create results, 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 more advanced than existing configurations made up of friction brakes and worm drive gearboxes. The integrated advantages of a planetary type gear train further allow for a compact assembly. The system’s hollow through the guts result spur shaft can complete wiring to a rotating connection, and also the simple insertion of downstream devices shafts. This would be especially useful for cable drums winding electrified cable, and turntables with electrics/electronics up to speed, for example.
The inventive gear system moreover addresses certain drawbacks of similar existing gear systems, e.g., vibration and noise conditions that are unacceptable in certain settings (such as for example during theatrical performances) and burdensome maintenance through the program lubrication of the machine gears.
To address such disadvantages, briefly described, the self-locking, non-backdrivable gear program of today’s invention comprises a primary motor insight and self-lubricating gear package. The primary motor insight 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 gear. 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 mounted to the ring gear and seal the parts within the ring gear so as to allow the internal self-lubrication of the gearbox through a volume of lubricant.
One or more world locking gears is rotatably mounted within the ring gear, whereby the planet equipment rotates with the ring gear and also rotates about its own mounting axis. The result spur gear is rotatably installed within the ring equipment, in a radially inward, concentric regards to the ring gear, and additional includes an result shaft adapted for mounting to the drive shaft. The output spur equipment has N+/−X amount of gear tooth in meshing engagement with the planet gear. The fixed spur gear is fixedly installed around the result shaft and positioned adjacent to the result spur gear. The fixed spur equipment has N number of gear tooth in meshing engagement with the earth gear tooth. The fixed and output spur gears have substantially similar diameters to permit the fixed and result spur gear teeth to considerably align while engaging with the earth gear. The fixed and result spur gear teeth each comprise a noise-dampening pressure position configuration to angularly compliment the earth gear teeth.
Functioning, rotation of the primary motor input causes rotation of the band gear which causes rotation of the earth gear which causes rotation of the output spur gear which in turn causes rotation of the drive shaft. Nevertheless, in the absence of rotation of the ring gear, any rotational pressure put on the output spur equipment (electronic.g., via the result shaft) will drive the considerably aligned fixed and output gear tooth to lock the planet locking gear set up.
Additional 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 may be rotatably installed within the band gear in a 180° off-arranged relation with respect to the first world locking equipment, about the entire 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 output spur gear the teeth. In the absence of rotation of the band gear, any rotational push put on the output spur gear will drive the fixed and result spur gear tooth to lock the initial and second world 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 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 output spur equipment. The pressure angle configuration could be from about 45 degrees to about 25 degrees. The pressure angle configuration may more preferably be from about 40 degrees to 30 degrees. The pressure position configuration may most preferably be about 35 degrees. The components of the gearbox may be made from metal, plastic-type material, composite, ceramic, wooden, plywood, steel powder, or combinations thereof.
Additional objects, advantages and novel top features of today’s invention will be established in part in the description which follows, and will 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 gear units is a little tooth lead angle of the worm and therefore 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 required. A worm equipment unit is known as self-locking at standstill if, with worm wheel generating, beginning with standstill is impossible. This is the case with ATLANTA wheel units and gear models when the lead angle is certainly <5°. A worm gear unit is considered self-locking from the running condition if the apparatus unit involves a standstill whilst getting backdriven. This 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 fasten. To avoid overstressing of the worm gear drive due to the high kinetic energy involved, you should furthermore allow for a certain running-down period after stopping the input.
