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 regards to the first planet locking gear, 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 own respective mounting axes while engaging said fixed and output spur gear teeth, and whereby in the absence of rotation of the band gear a rotational force applied to said output spur gear will power said fixed and output 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 system offers a simple and low-cost self-lubricating gearbox that can be driven in a forward and invert direction through 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 built-into any rotating machinery which utilizes a winch/drum. As such, these inventive equipment systems have particular program in neuro-scientific overhead lifting machinery, although the invention isn’t 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, 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.
Regarding 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 included benefits of a planetary type equipment train further enable a compact assembly. The system’s hollow through the guts output spur shaft can pass wiring through to a rotating connection, and also the simple insertion of downstream equipment shafts. This would be especially useful for cable drums winding electrified cable, and turntables with electrics/consumer electronics on board, for example.
The inventive gear program moreover addresses certain drawbacks of similar existing gear systems, e.g., vibration and noise conditions that are unacceptable in certain settings (such as 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 main motor insight and self-lubricating gear box. 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 equipment, and output spur equipment. The input ring equipment is mounted 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 equipment so as to permit the inner self-lubrication of the gearbox through a level 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 in addition rotates about its own mounting axis. The output spur gear is rotatably installed within the ring equipment, in a radially inward, concentric regards to the ring equipment, and further includes an output shaft adapted for mounting to the drive shaft. The output spur equipment has N+/−X quantity of gear tooth in meshing engagement with the earth equipment. The fixed spur gear is fixedly mounted around the result shaft and positioned next to the output spur gear. The fixed spur equipment has N quantity of gear tooth in meshing engagement with the planet gear the teeth. The fixed and output spur gears have substantially similar diameters to allow the fixed and result spur gear tooth to considerably align while engaging with the earth equipment. The fixed and result spur gear the teeth each comprise a noise-dampening pressure position configuration to angularly compliment the earth gear teeth.
In operation, rotation of the primary electric motor input causes rotation of the ring 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. However, in the lack of rotation of the band gear, any rotational power put on the output spur gear (electronic.g., via the result shaft) will pressure the considerably aligned fixed and output gear teeth to lock the planet locking gear in place.
Various other aspects of the machine are provided herein. For example, in an embodiment of the system having two world locking gears, the second planet locking gear could be rotatably mounted within the band gear in a 180° off-arranged 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 very own respective installation axes while engaging the set and output spur gear the teeth. In the absence of rotation of the band gear, any rotational drive put on the output spur equipment will pressure the fixed and result spur gear tooth to lock the first and second planet gears in place.
The principal 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 primary 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 may be an O-band or shaft seal. The gearbox may further comprise a ball bearing band positioned on the result 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 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 components of the gearbox could be made from metal, plastic-type material, composite, ceramic, wood, plywood, metallic 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 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 gear units is a small tooth business lead angle of the worm and thus an efficiency of η ≤ 0,5 with worm generating. Consequently self-locking gear products are generally uneconomical when high performances and lengthy operating times are required. A worm equipment unit is considered self-locking at standstill if, with worm wheel traveling, starting from standstill is difficult. This is the case with ATLANTA wheel units and gear devices when the lead position is usually <5°. A worm gear unit is known as self-locking from the operating condition if the apparatus unit involves a standstill whilst being backdriven. This is only feasible 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 because of the high kinetic energy included, you should furthermore enable a certain running-down time after stopping the insight.
