2. The apparatus system of claim 1 further comprising a self locking gearbox second planet locking gear rotatably mounted within said ring gear in 180° off-arranged relation with respect to the first planet locking equipment, about the entire 360° circumference of the ring equipment, whereby said 1st and second planet gears rotate with stated ring gear and also rotate about their very own respective mounting axes while engaging stated fixed and output spur gear teeth, and whereby in the lack of rotation of the band gear a rotational power applied to said output spur gear will force said fixed and output spur gear teeth to lock said initial and second world gears in place.
With reference to the use of the inventive gear system discussed herein, the machine provides a simple and low-cost self-lubricating gearbox which can be driven in a forward and reverse direction through an input motor shaft, but cannot 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 such, 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 in a position to wind in both a clockwise and counterclockwise direction, but not drop the load. These inventive equipment systems can also be applied to move scenery, create results, 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 made up of friction brakes and worm drive gearboxes. The included advantages of a planetary type gear train further allow for a compact assembly. The system’s hollow through the center output spur shaft can complete wiring to a rotating connection, as well as the basic insertion of downstream devices shafts. This might be especially useful for cable drums winding electrified cable, and turntables with electrics/electronics on board, for example.
The inventive gear program moreover addresses certain disadvantages of similar existing equipment systems, e.g., vibration and noise issues that are unacceptable in certain settings (such as for example 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 program of today’s invention comprises a major motor input and self-lubricating gear package. The primary motor input is definitely 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 gear, and output spur equipment. 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 components within the ring equipment so as to permit 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 band gear and also rotates about its mounting axis. The output spur gear is rotatably installed within the ring equipment, in a radially inward, concentric regards to the ring gear, and further includes an output shaft adapted for mounting to the drive shaft. The output spur gear has N+/−X amount 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 output spur equipment. The fixed spur equipment has N amount of gear teeth in meshing engagement with the earth gear teeth. The fixed and result spur gears have considerably similar diameters to allow the fixed and output spur gear the teeth to considerably align while engaging with the earth equipment. The fixed and output spur gear teeth each comprise a noise-dampening pressure position configuration to angularly compliment the earth gear teeth.
Functioning, rotation of the principal electric motor input causes rotation of the band gear which causes rotation of the planet 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 put on the output spur equipment (e.g., via the output shaft) will pressure the considerably aligned fixed and result gear the teeth to lock the planet 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 second planet locking gear could be rotatably mounted within the ring gear in a 180° off-set relation with respect to the first world locking gear, 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 result spur gear teeth. In the absence of rotation of the ring gear, any rotational pressure put on the output spur equipment will force the fixed and output spur gear teeth to lock the initial and second world gears in place.
The primary motor input may include a sprocket in meshing engagement with a timing belt. The principal motor input may or else include a sprocket in meshing engagement with a timing chain. The principal motor input may otherwise 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 result shaft to facilitate rotation of the result spur gear. The pressure position 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 position configuration may most ideally be about 35 degrees. The elements of the gearbox may be made from metal, plastic material, composite, ceramic, wooden, plywood, steel powder, or combinations thereof.
Additional objects, advantages and novel top features of today’s invention will be set forth in part 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.

Operation and Maintenance
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 thus an efficiency of η ≤ 0,5 with worm driving. Consequently self-locking gear systems are usually uneconomical when high performances and lengthy operating times are needed. A worm gear unit is known as self-locking at standstill if, with worm wheel driving, starting from standstill is impossible. This is the case with ATLANTA wheel models and gear units when the lead position is usually <5°. A worm gear unit is considered self-locking from the running condition if the gear unit comes to a standstill whilst being backdriven. This is only feasible with high gear ratios and very low speeds. Shocks and vibrations can neutralize the self-locking capacity! For that reason a self-locking tooth program cannot replace a brake or reverse-stroke locking mechanism. To avoid overstressing of the worm equipment drive due to the high kinetic energy involved, you should furthermore enable a certain running-down period after stopping the input.
