2. The gear system of claim 1 further comprising another planet locking gear rotatably mounted within said ring gear in 180° off-arranged relation with respect to the first planet locking equipment, about the full 360° circumference of the ring equipment, whereby said 1st and second planet gears rotate with said ring gear and in addition rotate about their own respective mounting axes while engaging stated fixed and result spur gear teeth, and whereby in the absence of rotation of the band gear a rotational drive applied to said output spur equipment will drive said fixed and output spur gear the teeth to lock said 1st and second world 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 reverse direction via an input engine 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 equipment systems have particular software in neuro-scientific overhead lifting machinery, although the invention isn’t 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 equipment 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 made up of friction brakes and worm drive gearboxes. The built-in benefits of a planetary type equipment train further allow for a compact assembly. The system’s hollow through the guts result spur shaft can complete wiring through to a rotating connection, along with the simple insertion of downstream products 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 program 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 schedule lubrication of the machine gears.
To address such disadvantages, briefly described, the self-locking, non-backdrivable gear program of the present invention comprises a main 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 equipment, and output spur equipment. The input ring equipment is mounted around the driveshaft and positioned in meshing engagement with the principal motor input. The band plate and seal configuration are mounted to the ring equipment and seal the elements within the ring gear so as to allow the internal 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 gear rotates with the band gear and also rotates about its mounting axis. The output spur equipment is rotatably installed within the ring gear, in a radially inward, concentric relation to the ring gear, and additional includes an result shaft adapted for installation to the drive shaft. The output spur equipment has N+/−X amount of gear tooth in meshing engagement with the planet equipment. The fixed spur gear is fixedly installed around the output shaft and positioned next to the result spur equipment. The fixed spur equipment has N number of gear the teeth in meshing engagement with the planet gear the teeth. The fixed and result spur gears have considerably similar diameters to allow the fixed and result spur gear the teeth to considerably align while engaging with the planet equipment. 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 principal electric motor input causes rotation of the ring gear which in turn 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 lack of rotation of the band gear, any rotational force put on the output spur gear (electronic.g., via the output shaft) will push the substantially aligned fixed and result gear tooth to lock the earth locking gear in place.
Additional aspects of the machine are provided herein. For instance, within an embodiment of the system having two planet 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 gear, about the full 360° circumference of the ring gear. The first and second world gears rotate with the band gear and in addition rotate about their personal respective installation axes while engaging the set and result spur gear teeth. In the absence of rotation of the band gear, any rotational push put on the output spur equipment will pressure the fixed and result spur gear the teeth to lock the 1st and second world gears in place.
The primary motor input may 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 or else include a sprocket in meshing engagement with a plurality of timing gears.
Each seal of the band plate and seal configuration could 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 gear. The pressure position configuration may be from about 45 degrees to about 25 degrees. The pressure position configuration may more preferably 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 material, composite, ceramic, wooden, plywood, steel powder, or combinations thereof.
Additional objects, advantages and novel top features of the present invention will be established in part 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 gear units is a little tooth business lead angle of the worm and thus an efficiency of η ≤ 0,5 with worm generating. Consequently self-locking gear devices are usually uneconomical when high performances and long operating times are necessary. A worm gear unit is considered self-locking at standstill if, with worm wheel driving, beginning with standstill is difficult. This is actually the case with ATLANTA wheel units and gear products when the lead position can be <5°. A worm gear unit is known as self-locking from the running condition if the apparatus unit involves a standstill whilst getting backdriven. That is only possible with high gear 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 fasten. To avoid overstressing of the worm gear drive because of the high kinetic energy involved, you should furthermore allow for a certain running-down time after stopping the insight.
