2. The apparatus system of claim 1 further comprising a second planet locking gear rotatably mounted within said ring gear in 180° off-arranged relation with regards to the first world locking equipment, about the full 360° circumference of the ring gear, whereby said 1st and second world gears rotate with stated ring gear and also rotate about their personal respective mounting axes while engaging said fixed and result spur gear the teeth, and whereby in the lack of rotation of the ring gear a rotational force applied to said output spur gear will force said fixed and result spur gear the teeth to lock said initial and second planet gears in place.
With reference to the use of the inventive gear system discussed herein, the machine offers a simple and low-cost self-lubricating gearbox that can be driven in a forward and reverse direction via 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 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 must be able to wind in both a clockwise and counterclockwise direction, however, not drop the strain. These inventive gear systems can also be put on 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 more advanced than existing configurations produced up of friction brakes and worm drive gearboxes. The built-in benefits of a planetary type gear train further enable a compact assembly. The system’s hollow through the center result spur shaft can pass wiring to a rotating connection, and also the basic insertion of downstream apparatus shafts. This might be particularly useful for cable drums winding electrified cable, and turntables with electrics/consumer electronics up to speed, for example.
The inventive gear program moreover addresses certain drawbacks of similar existing equipment systems, e.g., vibration and noise conditions that are unacceptable using settings (such as during theatrical performances) and burdensome maintenance through the schedule lubrication of the machine gears.
To address such disadvantages, briefly described, the self-locking, non-backdrivable gear program of the present invention comprises a main motor input and self-lubricating gear package. The primary motor input is 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 gear is mounted around the driveshaft and positioned in meshing engagement with the primary motor input. The band plate and seal configuration are mounted to the ring equipment and seal the parts within the ring gear so as to allow the inner self-lubrication of the gearbox through a volume of lubricant.
One or more planet locking gears is rotatably mounted within the band gear, whereby the earth gear rotates with the ring gear and also rotates about its mounting axis. The output spur equipment is rotatably installed within the ring gear, in a radially inward, concentric relation to the ring gear, and further includes an output shaft adapted for installation to the drive shaft. The output spur gear has N+/−X quantity of gear teeth in meshing engagement with the earth equipment. The fixed spur gear is fixedly mounted around the result 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 earth gear the teeth. The fixed and output spur gears have substantially similar diameters to permit the fixed and result spur gear tooth to considerably align while engaging with the earth gear. The fixed and result spur gear tooth each comprise a noise-dampening pressure position configuration to angularly compliment the earth 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 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 push applied to the output spur gear (e.g., via the result shaft) will push the considerably aligned fixed and output gear tooth to lock the earth locking gear set up.
Various other aspects of the machine are provided herein. For instance, in an embodiment of the system having two world locking gears, the next planet locking gear may be rotatably installed within the ring gear in a 180° off-set up relation with respect to the first world locking gear, about the entire 360° circumference of the ring gear. The initial and second world gears rotate with the band gear and in addition rotate about their own respective installation axes while engaging the set and output spur gear teeth. In the absence of rotation of the band gear, any rotational drive applied to the output spur gear will pressure the fixed and result spur gear tooth to lock the first and second planet gears in place.
The principal 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 band plate and seal configuration could be an O-band or shaft seal. The gearbox may additional comprise a ball bearing band positioned on the output shaft to facilitate rotation of the result spur equipment. 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 be about 35 degrees. The components of the gearbox could be made from metal, plastic-type, composite, ceramic, wood, plywood, steel powder, or combinations thereof.
Extra objects, advantages and novel top features of the present invention will be established partly in the description which follows, and can in part become obvious 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 gear units is a small tooth 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 lengthy operating times are necessary. A worm equipment unit is considered self-locking at standstill if, with worm wheel driving, beginning with standstill is not possible. This is actually the case with ATLANTA wheel models and gear models when the lead angle is certainly <5°. A worm gear unit is considered self-locking from the running condition if the gear unit comes to a standstill whilst becoming backdriven. This is only possible with high equipment ratios and incredibly low speeds. Shocks and vibrations can neutralize the self-locking capacity! Therefore a self-locking tooth program cannot replace a brake or reverse-stroke fasten. In order to avoid overstressing of the worm equipment drive due to the high kinetic energy included, you should furthermore allow for a certain running-down time after stopping the input.
