2. The apparatus system of claim 1 further comprising a second planet locking equipment rotatably mounted within stated ring gear in 180° off-set relation with regards to the first planet locking equipment, about the entire 360° circumference of the ring gear, whereby said first 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 the teeth, and whereby in the lack of rotation of the band gear a rotational pressure put on said output spur gear will force said fixed and output spur gear tooth to lock said first and second world gears in place.
With 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 via an input electric 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 equipment systems have particular program 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, however, not drop the strain. These inventive gear 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 superior to existing configurations produced up of friction brakes and worm drive gearboxes. The built-in advantages of a planetary type equipment train further allow for a compact assembly. The system’s hollow through the guts output spur shaft can pass wiring to a rotating connection, as well as the simple insertion of downstream equipment shafts. This would be especially useful for cable drums winding electrified cable, and turntables with electrics/electronic devices on board, for example.
The inventive gear program moreover addresses certain disadvantages 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 routine lubrication of the system gears.
To address such drawbacks, briefly described, the self-locking, non-backdrivable gear system of today’s invention comprises a main 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, band plate and seal configuration, planet locking equipment, fixed spur gear, and output spur gear. The input ring equipment is installed around the driveshaft and situated 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 permit the internal self-lubrication of the gearbox through a level of lubricant.
One or more planet locking gears is rotatably mounted within the ring gear, whereby the planet gear rotates with the ring gear and also rotates about its mounting axis. The output spur equipment is rotatably mounted within the ring equipment, 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 amount of gear tooth in meshing engagement with the planet gear. The fixed spur equipment is fixedly mounted around the output shaft and positioned next to the result spur gear. The fixed spur gear has N number of gear the teeth in meshing engagement with the planet gear the teeth. The fixed and output spur gears have substantially similar diameters to allow the fixed and output spur gear teeth to substantially align while engaging with the earth gear. 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 primary electric 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 ring gear, any rotational pressure applied to the output spur equipment (e.g., via the output shaft) will drive the substantially aligned fixed and output gear the teeth to lock the planet locking gear set up.
Additional aspects of the machine are provided herein. For instance, in an embodiment of the system having two planet locking gears, the second planet locking gear may be rotatably mounted within the band gear in a 180° off-set relation with regards to the first world locking gear, about the full 360° circumference of the ring gear. The first and second world gears rotate with the band gear and in addition rotate about their very own respective mounting axes while engaging the set and result spur gear teeth. In the absence of rotation of the band gear, any rotational push applied to the output spur equipment will force the fixed and output spur gear the teeth to lock the first 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 otherwise add 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 could be an O-ring or shaft seal. The gearbox may further comprise a ball bearing band positioned on the output shaft to facilitate rotation of the result spur equipment. The pressure angle 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 preferably be about 35 degrees. The elements of the gearbox may be made from metal, plastic, composite, ceramic, wood, plywood, metal powder, or combinations thereof.
Extra 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 with the attached figures.

Operation and Maintenance
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 thus an efficiency of η ≤ 0,5 with worm traveling. Consequently self-locking gear models are usually uneconomical when high performances and lengthy operating times are required. A worm gear unit is considered self-locking at standstill if, with worm wheel traveling, beginning with standstill is unattainable. This is the case with ATLANTA wheel units and gear units when the lead angle is definitely <5°. A worm gear unit is known as self-locking from the operating condition if the gear unit comes to a standstill whilst being backdriven. That 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 system cannot replace a brake or reverse-stroke fasten. To avoid overstressing of the worm gear drive due to the very high kinetic energy included, you should furthermore allow for a certain running-down period after stopping the insight.
