2. The gear system of claim 1 further comprising another planet locking gear rotatably mounted within stated ring gear in 180° off-established relation with regards to the first world locking equipment, about the entire 360° circumference of the ring gear, whereby said initial and second planet gears rotate with said ring gear and also rotate about their personal respective installation axes while engaging stated fixed and output spur gear teeth, and whereby in the absence of rotation of the band gear a rotational push applied to said output spur gear will drive said fixed and output spur gear tooth to lock said 1st and second planet 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 can’t be back-driven through its output gearing. By virtue of its configuration as a ring gear, the invention could be effectively built-into any rotating machinery which utilizes a winch/drum. As this kind of, these inventive gear systems have particular application in neuro-scientific overhead lifting machinery, although the invention is not so limited. For instance, 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 can also be put on move scenery, create effects, 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 superior to existing configurations produced up of friction brakes and worm drive gearboxes. The built-in benefits of a planetary type equipment train further enable a compact assembly. The system’s hollow through the guts output spur shaft can move wiring to a rotating connection, along with the basic insertion of downstream equipment shafts. This might be particularly useful for cable drums winding electrified cable, and turntables with electrics/electronics up to speed, for example.
The inventive gear system moreover addresses certain disadvantages of similar existing gear systems, e.g., vibration and noise issues that are unacceptable using 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 today’s invention comprises a principal 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 gear is mounted around the driveshaft and positioned in meshing engagement with the principal motor input. The ring plate and seal configuration are mounted to the ring equipment and seal the elements within the ring equipment so as to allow the internal 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 also rotates about its own mounting axis. The result spur gear is rotatably mounted within the ring equipment, in a radially inward, concentric relation to the ring gear, and further includes an result shaft adapted for installation to the drive shaft. The output spur gear has N+/−X quantity of gear the teeth in meshing engagement with the planet equipment. The fixed spur gear is fixedly installed around the output shaft and positioned next to the output spur gear. The fixed spur gear has N quantity of gear teeth in meshing engagement with the earth gear tooth. The fixed and result spur gears have considerably similar diameters to permit the fixed and result spur gear teeth to considerably align while engaging with the earth equipment. The fixed and result spur gear teeth each comprise a noise-dampening pressure angle configuration to angularly compliment the earth gear teeth.
Functioning, rotation of the primary engine input causes rotation of the band gear which causes rotation of the earth gear which causes rotation of the output spur gear which causes rotation of the drive shaft. However, in the absence of rotation of the ring gear, any rotational force applied to the output spur gear (electronic.g., via the output shaft) will pressure the considerably aligned fixed and output gear tooth to lock the planet locking gear set up.
Other aspects of the machine are provided herein. For instance, within an embodiment of the system having two world locking gears, the next planet locking gear may be rotatably installed within the band gear in a 180° off-arranged relation with respect to the first planet locking gear, about the entire 360° circumference of the ring gear. The initial and second planet gears rotate with the band gear and also rotate about their very own respective mounting axes while engaging the fixed and result spur gear tooth. In the absence of rotation of the ring gear, any rotational power put on the output spur gear will power the fixed and result spur gear teeth to lock the initial and second planet gears in place.
The principal motor input can 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 ring plate and seal configuration could be an O-band or shaft seal. The gearbox may further comprise a ball bearing ring 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 parts of the gearbox may be made from metal, plastic-type, composite, ceramic, wooden, plywood, steel powder, or combinations thereof.
Extra objects, advantages and novel 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 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 business lead angle of the worm and thus an efficiency of η ≤ 0,5 with worm traveling. Consequently self-locking gear devices are generally uneconomical when high performances and lengthy operating times are required. A worm gear unit is considered self-locking at standstill if, with worm wheel driving, beginning with standstill is extremely hard. This is actually the case with ATLANTA wheel units and gear products when the lead position is certainly <5°. A worm gear unit is considered self-locking from the running condition if the apparatus unit comes to a standstill whilst getting backdriven. That is only possible with high equipment ratios and incredibly low speeds. Shocks and vibrations can neutralize the self-locking capacity! Consequently a self-locking tooth program cannot replace a brake or reverse-stroke fasten. In order to avoid overstressing of the worm gear drive because of the very high kinetic energy included, you should furthermore enable a certain running-down time after stopping the insight.
