2. The gear system of claim 1 further comprising another planet locking gear rotatably mounted within said ring equipment in 180° off-established relation with regards to the first planet locking gear, about the full 360° circumference of the ring gear, whereby said 1st and second planet gears rotate with stated 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 ring gear a rotational power put on said output spur equipment will push said fixed and output spur gear 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 offers a simple and low-cost self-lubricating gearbox that can be driven in a forward and reverse direction through an input electric motor shaft, but cannot be back-driven through its output gearing. By virtue of its configuration as a band gear, the invention could be effectively integrated into any rotating machinery which utilizes a winch/drum. As this kind of, these inventive gear systems have particular application in the field of 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 able to wind in both a clockwise and counterclockwise direction, however, not drop the load. These inventive equipment systems may also be put on move scenery, create results, 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 superior to existing configurations made 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 guts result spur shaft can complete wiring to a rotating connection, and also the simple 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 program moreover addresses certain drawbacks of similar existing gear systems, e.g., vibration and noise issues that are unacceptable using settings (such as during theatrical performances) and burdensome maintenance through the routine lubrication of the machine gears.
To address such disadvantages, briefly described, the self-locking, non-backdrivable gear program of the present invention comprises a principal motor input and self-lubricating gear box. The primary motor insight 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 gear, fixed spur equipment, and output spur equipment. The input ring equipment is mounted around the driveshaft and situated in meshing engagement with the primary motor input. The ring plate and seal configuration are installed to the ring equipment and seal the components within the ring equipment 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 regards to the ring gear, and further includes an result shaft adapted for installation to the drive shaft. The output spur equipment has N+/−X number of gear tooth in meshing engagement with the planet gear. The fixed spur gear is fixedly installed around the result shaft and positioned adjacent to the output spur gear. The fixed spur equipment has N quantity of gear tooth in meshing engagement with the earth gear the teeth. The fixed and output spur gears have considerably similar diameters to permit the fixed and output spur gear tooth to considerably align while engaging with the earth 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 primary electric motor input causes rotation of the band gear which in turn causes rotation of the earth gear which in turn causes rotation of the output spur gear which in turn causes rotation of the drive shaft. However, in the lack of rotation of the band gear, any rotational push applied to the output spur equipment (e.g., via the output shaft) will drive the substantially aligned fixed and result gear tooth to lock the earth locking gear set up.
Various other aspects of the machine are provided herein. For instance, within an embodiment of the machine having two planet locking gears, the next planet locking gear may be rotatably mounted within the ring gear in a 180° off-arranged relation with regards to the first world locking gear, about the full 360° circumference of the ring gear. The 1st and second world gears rotate with the band gear and also rotate about their personal respective mounting axes while engaging the fixed and result spur gear tooth. In the absence of rotation of the ring gear, any rotational drive put on the output spur equipment will force the fixed and result spur gear tooth 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 may be an O-ring or shaft seal. The gearbox may additional comprise a ball bearing ring positioned on the output shaft to facilitate rotation of the result spur gear. 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 preferably become about 35 degrees. The elements of the gearbox could be made from metal, plastic-type, composite, ceramic, wooden, plywood, steel powder, or combinations thereof.
Extra objects, advantages and novel features of the present invention will be set forth partly in the description which follows, and will in part become apparent to those in the practice of the invention, when regarded as with the attached figures.

Operation and Maintenance
Self-locking property of Worm Gear Units
A precondition for the self-locking quality of equipment 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 devices are generally uneconomical when high performances and long operating times are needed. A worm equipment unit is considered self-locking at standstill if, with worm wheel traveling, starting from standstill is unattainable. This is the case with ATLANTA wheel pieces and gear products when the lead angle is certainly <5°. A worm gear unit is considered self-locking from the running condition if the gear unit involves a standstill whilst being backdriven. This is only possible with high equipment ratios and very 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 equipment drive because of the very high kinetic energy involved, you self locking gearbox should furthermore enable a certain running-down period after stopping the insight.
