2. The gear system of claim 1 further comprising a second planet locking gear rotatably mounted within stated ring gear in 180° off-arranged relation with regards to the first planet locking gear, about the entire 360° circumference of the ring equipment, whereby said initial and second world gears rotate with stated ring gear and in addition rotate about their very own respective mounting axes while engaging stated fixed and result spur gear the teeth, and whereby in the lack of rotation of the band gear a rotational drive applied to said output spur equipment will push said fixed and output spur gear teeth to lock said initial and second planet gears in place.
With reference to the application 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 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 built-into any rotating machinery which utilizes a winch/drum. As this kind of, these inventive equipment systems have particular app 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 load. These inventive gear systems can also be put on move scenery, create effects, and manipulate overhead light 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 integrated benefits of a planetary type equipment train further enable a concise assembly. The system’s hollow through the guts output spur shaft can complete wiring through to a rotating connection, along with the basic insertion of downstream tools shafts. This would be particularly useful for cable drums winding electrified cable, and turntables with electrics/electronics on board, for example.
The inventive gear system moreover addresses certain drawbacks 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 regimen lubrication of the machine gears.
To address such drawbacks, briefly described, the self-locking, non-backdrivable gear system of the present invention comprises a primary motor insight and self-lubricating gear container. The primary motor insight is definitely adapted for rotation of the gearbox about the axis of a drive shaft. The gearbox comprises an input ring gear, ring plate and seal configuration, planet locking equipment, fixed spur gear, and output spur gear. The input ring gear is installed around the driveshaft and positioned in meshing engagement with the primary motor input. The ring plate and seal configuration are installed to the ring gear and seal the elements within the ring equipment so as to allow the inner 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 earth 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 regards to the ring equipment, and additional includes an output shaft adapted for mounting to the drive shaft. The output spur equipment has N+/−X quantity of gear the teeth in meshing engagement with the planet gear. The fixed spur equipment is fixedly installed around the output shaft and positioned next to the result spur equipment. The fixed spur equipment has N quantity of gear tooth in meshing engagement with the earth gear tooth. The fixed and result spur gears have substantially similar diameters to allow the fixed and output spur gear the teeth to substantially align while engaging with the planet gear. The fixed and result spur gear tooth each comprise a noise-dampening pressure angle 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 causes rotation of the drive shaft. Nevertheless, in the lack of rotation of the ring gear, any rotational power applied to the output spur gear (electronic.g., via the result shaft) will force the considerably aligned fixed and result gear tooth to lock the planet locking gear in place.
Various other aspects of the system are provided herein. For instance, in an embodiment of the machine having two planet locking gears, the next planet locking gear could be rotatably installed within the band gear in a 180° off-set up relation with respect to the first planet locking equipment, 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 set and result spur gear teeth. In the absence of rotation of the ring gear, any rotational power put on the output spur equipment will push the fixed and result spur gear tooth to lock the 1st and second world gears in place.
The principal motor input may include a sprocket in meshing engagement with a timing belt. The primary motor input may or else add 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 may be an O-ring or shaft seal. The gearbox may additional comprise a ball bearing band positioned on the result shaft to facilitate rotation of the result spur equipment. The pressure position configuration may 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 preferably end up being about 35 degrees. The components of the gearbox may 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 established partly in the description which follows, and can 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 little tooth lead angle of the worm and thus an efficiency of η ≤ 0,5 with worm driving. Consequently self-locking gear systems are generally uneconomical when high performances and long operating times are necessary. A worm gear unit is considered self-locking at standstill if, with worm wheel generating, beginning with standstill is extremely hard. This is the case with ATLANTA wheel sets and gear devices when the lead position is certainly <5°. A worm gear unit is known as self-locking from the working condition if the apparatus unit involves a standstill whilst being backdriven. This is only feasible with high equipment ratios and very low speeds. Shocks and vibrations can neutralize the self-locking capacity! Therefore a self-locking tooth program cannot replace a brake or reverse-stroke fasten. In order to avoid overstressing of the worm equipment drive because of the high kinetic energy included, you should furthermore allow for a certain running-down time after stopping the insight.
