2. The gear system of claim 1 further comprising a second planet locking equipment rotatably mounted within said ring gear in 180° off-arranged relation with respect to the first world locking gear, about the full 360° circumference of the ring gear, whereby said 1st and second world gears rotate with said ring gear and in addition rotate about their own respective installation axes while engaging said fixed and output spur gear the teeth, and whereby in the lack of rotation of the band gear a rotational pressure applied to said output spur gear will force said fixed and output spur gear the teeth to lock said initial and second world gears in place.
With reference to the use 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 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 integrated into any rotating machinery which utilizes a winch/drum. As such, these inventive gear systems have particular software in the field of overhead lifting machinery, although the invention is not so limited. For example, 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 load. 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 superior to existing configurations produced up of friction brakes and worm drive gearboxes. The integrated advantages of a planetary type gear train further allow for a compact assembly. The system’s hollow through the center output spur shaft can move wiring through to a rotating connection, and also the basic insertion of downstream devices 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 program 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 program lubrication of the machine gears.
To address such drawbacks, briefly described, the self-locking, non-backdrivable gear program of today’s invention comprises a main motor insight 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 input ring gear, ring plate and seal configuration, planet locking gear, fixed spur equipment, 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 installed to the ring gear and seal the components within the ring equipment so as to allow the internal self-lubrication of the gearbox through a level of lubricant.
One or more planet locking gears is rotatably mounted within the ring gear, whereby the earth equipment rotates with the ring gear and in addition rotates about its own mounting axis. The output spur equipment is rotatably mounted within the ring equipment, in a radially inward, concentric regards to the ring gear, and additional includes an output shaft adapted for mounting to the drive shaft. The output spur equipment has N+/−X number of gear tooth in meshing engagement with the planet equipment. The fixed spur equipment is fixedly mounted around the result shaft and positioned adjacent to the result spur equipment. The fixed spur gear has N quantity of gear tooth in meshing engagement with the planet gear the teeth. The fixed and output spur gears have substantially similar diameters to allow the fixed and result spur gear the teeth to considerably align while engaging with the earth gear. The fixed and output spur gear teeth each comprise a noise-dampening pressure position configuration to angularly compliment the earth gear teeth.
Functioning, rotation of the principal 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. However, in the lack of rotation of the band gear, any rotational drive put on the output spur gear (e.g., via the output shaft) will force the considerably aligned fixed and result gear teeth to lock the earth locking gear set up.
Other 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 mounted 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 1st and second world gears rotate with the band gear and also rotate about their very own respective mounting axes while engaging the set and output spur gear teeth. In the absence of rotation of the ring gear, any rotational power put on the output spur gear will force the fixed and output spur gear the teeth to lock the initial and second planet 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 add a sprocket in meshing engagement with a plurality of timing gears.
Each seal of the band plate and seal configuration could be an O-band or shaft seal. The gearbox may additional comprise a ball bearing band positioned on the result shaft to facilitate rotation of the output 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 position configuration may most preferably end up being about 35 degrees. The parts of the gearbox may be made from metal, plastic-type material, composite, ceramic, wooden, plywood, metal powder, or combinations thereof.
Extra objects, advantages and novel top features of the present 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 regarded 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 lead angle of the worm and thus an efficiency of η ≤ 0,5 with worm generating. Consequently self-locking gear systems are usually uneconomical when high performances and lengthy operating times are required. A worm equipment unit is considered self-locking at standstill if, with worm wheel driving, starting from standstill is impossible. This is actually the case with ATLANTA wheel sets and gear products when the lead angle is usually <5°. A worm gear unit is considered self-locking from the operating condition if the gear unit comes to a standstill whilst becoming backdriven. That is only possible with high gear ratios and very low speeds. Shocks and vibrations can neutralize the self-locking capacity! As a result a self-locking tooth system cannot replace a brake or reverse-stroke fasten. 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 period after stopping the input.
