2. The gear system of claim 1 further comprising another planet locking equipment rotatably mounted within stated ring gear in 180° off-established relation with regards to the first world locking gear, about the full 360° circumference of the ring gear, whereby said initial and second world gears rotate with said ring gear and also rotate about their own respective installation axes while engaging said fixed and output spur gear the teeth, and whereby in the absence of rotation of the ring gear a rotational drive applied to said output spur equipment will power said fixed and result spur gear the teeth to lock said 1st and second planet gears in place.
With reference to the application 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 invert 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 can be effectively integrated into any rotating machinery which utilizes a winch/drum. As this kind of, these inventive gear systems have particular program 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, but not drop the strain. These inventive gear systems may 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 allow for a concise assembly. The system’s hollow through the guts result spur shaft can move wiring through to a rotating connection, and also the simple insertion of downstream equipment shafts. This might be particularly 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 disadvantages of similar existing gear systems, e.g., vibration and noise conditions that are unacceptable using settings (such as 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 system of the present invention comprises a primary motor insight and self-lubricating gear container. The primary motor insight is certainly 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 equipment, and output spur gear. The input ring equipment is installed around the driveshaft and situated in meshing engagement with the principal motor input. The band plate and seal configuration are installed to the ring gear and seal the parts within the ring gear so as to allow the inner self-lubrication of the gearbox through a level of lubricant.
One or more planet locking gears is rotatably mounted within the band gear, whereby the earth gear rotates with the ring gear and in addition rotates about its own mounting axis. The result spur equipment is rotatably mounted within the ring gear, in a radially inward, concentric relation to the ring equipment, and further includes an result shaft adapted for mounting to the drive shaft. The output spur equipment has N+/−X number of gear the teeth in meshing engagement with the earth equipment. The fixed spur gear is fixedly installed around the output shaft and positioned adjacent to the output spur gear. The fixed spur gear has N quantity of gear the teeth in meshing engagement with the planet gear teeth. The fixed and output spur gears have substantially similar diameters to permit the fixed and result spur gear tooth to substantially align while engaging with the planet gear. The fixed and result spur gear the teeth each comprise a noise-dampening pressure angle configuration to angularly compliment the planet gear teeth.
In operation, rotation of the primary electric motor input causes rotation of the ring gear which in turn 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 drive applied to the output spur equipment (e.g., via the result shaft) will push the substantially aligned fixed and output gear the teeth to lock the planet locking gear in place.
Various other aspects of the system are provided herein. For example, in 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-established relation with regards to the first planet locking equipment, about the full 360° circumference of the ring gear. The first and second planet gears rotate with the ring gear and in addition rotate about their own respective mounting axes while engaging the set and output spur gear tooth. In the lack of rotation of the band gear, any rotational drive applied to the output spur gear will push the fixed and result spur gear the teeth to lock the first 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 otherwise add a sprocket in meshing engagement with a timing chain. The primary motor input may or else 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 further comprise a ball bearing ring positioned on the result shaft to facilitate rotation of the output spur equipment. The pressure angle configuration could be from about 45 degrees to about 25 degrees. The pressure angle configuration may more preferably 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 could be made from metal, plastic-type, composite, ceramic, wood, plywood, metal powder, or combinations thereof.
Extra objects, advantages and novel features of the present invention will be established partly in the description which follows, and will in part become apparent 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 little tooth business lead angle of the worm and therefore an efficiency of η ≤ 0,5 with worm generating. Consequently self-locking gear devices are generally uneconomical when high performances and long operating times are required. A worm gear unit is considered self-locking at standstill if, with worm wheel traveling, beginning with standstill is extremely hard. This is actually the case with ATLANTA wheel sets and gear models when the lead angle is certainly <5°. A worm gear unit is considered self-locking from the operating condition if the apparatus unit comes to a standstill whilst becoming backdriven. That is only possible with high gear ratios and incredibly low speeds. Shocks and vibrations can neutralize the self-locking capacity! Consequently a self-locking tooth system 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 allow for a certain running-down time after stopping the insight.
