2. The gear system of claim 1 further comprising another planet locking gear rotatably mounted within said ring equipment in 180° off-arranged relation with respect to the first world locking equipment, about the full 360° circumference of the ring equipment, whereby said 1st 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 teeth, and whereby in the absence of rotation of the band gear a rotational pressure put on said output spur gear will power said fixed and result spur gear teeth to lock said 1st and second planet 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 that can be driven in a forward and invert direction through 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 built-into any rotating machinery which utilizes a winch/drum. As this kind of, these inventive equipment systems have particular app 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 in a position to wind in both a clockwise and counterclockwise direction, however, not drop the strain. These inventive equipment systems may also be applied to 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 included advantages of a planetary type equipment train further allow for a compact assembly. The system’s hollow through the center output spur shaft can move wiring to a rotating connection, as well as the basic insertion of downstream devices shafts. This would be especially useful for cable drums winding electrified cable, and turntables with electrics/consumer electronics up to speed, for example.
The inventive gear system moreover addresses certain drawbacks 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 routine lubrication of the machine gears.
To address such drawbacks, briefly described, the self-locking, non-backdrivable gear program of the present invention comprises a major motor insight and self-lubricating gear container. The primary motor input can be adapted for rotation of the gearbox about the axis of a drive shaft. The gearbox comprises an input ring gear, band plate and seal configuration, planet locking gear, fixed spur gear, and output spur gear. The input ring gear is installed around the driveshaft and situated in meshing engagement with the primary motor input. The ring plate and seal configuration are mounted to the ring equipment and seal the elements 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 planet equipment rotates with the band gear and in addition rotates about its mounting axis. The result spur equipment is rotatably installed within the ring equipment, in a radially inward, concentric relation to the ring equipment, and additional includes an output shaft adapted for installation to the drive shaft. The output spur equipment has N+/−X amount of gear teeth in meshing engagement with the earth gear. The fixed spur gear is fixedly mounted around the result shaft and positioned adjacent to the output spur equipment. The fixed spur gear has N number of gear the teeth in meshing engagement with the earth gear the teeth. The fixed and result spur gears have substantially similar diameters to allow the fixed and result spur gear teeth to considerably align while engaging with the planet equipment. 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 planet gear which in turn causes rotation of the output spur gear which causes rotation of the drive shaft. Nevertheless, in the absence of rotation of the ring gear, any rotational push applied to the output spur equipment (e.g., via the result shaft) will pressure the considerably aligned fixed and output gear tooth to lock the earth locking gear set up.
Various other aspects of the system are provided herein. For example, in an embodiment of the system having two planet locking gears, the next planet locking gear could be rotatably installed within the band gear in a 180° off-established relation with regards to the first planet locking gear, about the full 360° circumference of the ring gear. The first and second world gears rotate with the ring gear and in addition rotate about their personal respective mounting axes while engaging the fixed and result spur gear teeth. In the absence of rotation of the ring gear, any rotational power applied to the output spur gear will force the fixed and result spur gear teeth 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 or else include a sprocket in meshing engagement with a timing chain. The principal motor input may otherwise include 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 ring positioned on the result shaft to facilitate rotation of the result spur equipment. The pressure angle configuration may 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, steel powder, or combinations thereof.
Additional objects, advantages and novel top features of today’s invention will be set forth partly 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.

Self-locking property of Worm Gear Units
A precondition for the self-locking quality of equipment units is a small tooth business lead angle of the worm and therefore an efficiency of η ≤ 0,5 with worm driving. Consequently self-locking gear devices are generally uneconomical when high performances and lengthy operating times are necessary. A worm gear unit is considered self-locking at standstill if, with worm wheel generating, starting from standstill is unattainable. This is the case with ATLANTA wheel units and gear models when the lead position is certainly <5°. A worm gear unit is known as self-locking from the working condition if the gear unit comes to a standstill whilst being backdriven. That is only feasible with high equipment ratios and incredibly low speeds. Shocks and vibrations can neutralize the self-locking capacity! For that reason a self-locking tooth system cannot replace a brake or reverse-stroke locking mechanism. To avoid overstressing of the worm gear drive due to the very high kinetic energy included, you should furthermore enable a certain running-down period after stopping the insight.
