2. The apparatus system of claim 1 further comprising a second planet locking gear rotatably mounted within said ring equipment in 180° off-set relation with respect to the first planet locking equipment, about the full 360° circumference of the ring gear, whereby said first and second world gears rotate with said ring gear and in addition rotate about their very own respective mounting axes while engaging stated fixed and output spur gear teeth, and whereby in the absence of rotation of the band gear a rotational force applied to said output spur gear will push said fixed and output spur gear the teeth to lock said 1st and second world gears in place.
With reference to the use of the inventive gear system discussed herein, the machine offers 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 can be effectively built-into any rotating machinery which utilizes a winch/drum. As this kind of, these inventive gear systems have particular app 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 must be in a position to wind in both a clockwise and counterclockwise direction, however, not drop the strain. These inventive equipment systems may also be applied to move scenery, create effects, and manipulate overhead light and machinery during theatrical performances.
In the case of 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 advantages of a planetary type gear train further enable a compact assembly. The system’s hollow through the center result spur shaft can complete wiring to a rotating connection, and also the simple insertion of downstream tools shafts. This might be especially 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 drawbacks of similar existing equipment 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 routine lubrication of the machine gears.
To address such drawbacks, briefly described, the self-locking, non-backdrivable gear system of today’s invention comprises a main motor insight and self-lubricating gear package. 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 equipment, fixed spur equipment, and output spur equipment. The input ring gear is mounted around the driveshaft and situated in meshing engagement with the principal motor input. The band plate and seal configuration are mounted to the ring equipment 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 ring gear, whereby the planet equipment rotates with the band gear and in addition rotates about its mounting axis. The result spur gear is rotatably installed within the ring equipment, in a radially inward, concentric relation to the ring equipment, and additional includes an result shaft adapted for installation to the drive shaft. The output spur equipment has N+/−X quantity of gear teeth in meshing engagement with the earth gear. The fixed spur gear is fixedly installed around the result 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 earth gear tooth. The fixed and output spur gears have considerably similar diameters to allow the fixed and output spur gear the teeth to substantially align while engaging with the earth gear. The fixed and result spur gear the 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 in turn causes rotation of the planet 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 pressure applied to the output spur gear (electronic.g., via the result shaft) will force the substantially aligned fixed and output gear teeth to lock the planet locking gear set up.
Additional aspects of the system are provided herein. For instance, within an embodiment of the machine having two planet locking gears, the next planet locking gear could be rotatably installed within the ring gear in a 180° off-arranged relation with regards to the first world locking equipment, about the full 360° circumference of the ring gear. The initial and second planet gears rotate with the band gear and also rotate about their own respective mounting axes while engaging the set and output spur gear teeth. In the lack of rotation of the ring gear, any rotational pressure applied to the output spur gear will power the fixed and result spur gear teeth to lock the 1st and second world 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 add a sprocket in meshing engagement with a timing chain. The primary 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 ring positioned on the result shaft to facilitate rotation of the result spur equipment. The pressure position configuration could 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 ideally end up being about 35 degrees. The elements of the gearbox may be made from metal, plastic-type, composite, ceramic, wood, plywood, metallic powder, or combinations thereof.
Extra objects, advantages and novel top features of the present invention will be set forth in part 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.

Self-locking property of Worm Gear Units
A precondition for the self-locking quality of gear units is a small tooth business lead angle of the worm and thus an efficiency of η ≤ 0,5 with worm generating. Consequently self-locking gear models are usually uneconomical when high performances and lengthy operating times are needed. A worm equipment 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 units when the lead position can be <5°. A worm gear unit is considered self-locking from the working condition if the apparatus unit comes to a standstill whilst getting backdriven. This is only feasible with high equipment ratios and incredibly 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 locking mechanism. In order to avoid overstressing of the worm equipment drive due to the very high kinetic energy included, you should furthermore enable a certain running-down period after stopping the input.
