2. The apparatus system of claim 1 further comprising a second planet locking gear rotatably mounted within stated ring gear in 180° off-established relation with respect to the first world locking equipment, about the entire 360° circumference of the ring equipment, whereby said 1st and second world gears rotate with stated ring gear and also rotate about their very own respective mounting axes while engaging said fixed and output spur gear tooth, and whereby in the lack of rotation of the band gear a rotational force applied to said output spur gear will drive said fixed and output spur gear teeth to lock said 1st and second world 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 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 could 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 isn't so limited. For instance, winch machinery that utilizes a cable winding onto a cylindrical or pile-up drum should be in a position to wind in both a clockwise and counterclockwise direction, but not drop the strain. These inventive gear systems may also be applied to move scenery, create results, and manipulate overhead lighting 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 more advanced than existing configurations made up of friction brakes and worm drive gearboxes. The built-in benefits of a planetary type gear train further enable a concise assembly. The system's hollow through the center output spur shaft can move wiring to a rotating connection, along with the basic insertion of downstream devices shafts. This might be particularly useful for cable drums winding electrified cable, and turntables with electrics/electronics up to speed, for example.
The inventive gear program moreover addresses certain drawbacks of similar existing gear systems, e.g., vibration and noise conditions that are unacceptable in certain 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 major 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, band plate and seal configuration, planet locking gear, fixed spur gear, and output spur equipment. The input ring equipment is mounted around the driveshaft and positioned in meshing engagement with the primary motor input. The ring plate and seal configuration are mounted to the ring gear and seal the components within the ring equipment so as to allow the inner 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 ring gear and in addition rotates about its mounting axis. The result spur gear is rotatably mounted within the ring gear, in a radially inward, concentric regards to the ring gear, and further includes an output shaft adapted for installation to the drive shaft. The output spur gear has N+/−X number of gear teeth in meshing engagement with the earth gear. The fixed spur equipment is fixedly installed around the output shaft and positioned next to the output spur equipment. The fixed spur gear has N quantity of gear teeth in meshing engagement with the planet gear teeth. The fixed and result spur gears have substantially similar diameters to permit the fixed and output spur gear the teeth to considerably align while engaging with the earth equipment. The fixed and output spur gear tooth each comprise a noise-dampening pressure position configuration to angularly compliment the earth gear teeth.
Functioning, rotation of the primary motor input causes rotation of the band gear which in turn causes rotation of the planet 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 ring gear, any rotational push put on the output spur equipment (electronic.g., via the output shaft) will pressure the substantially aligned fixed and result gear teeth to lock the planet locking gear set up.
Additional aspects of the machine are provided herein. For example, 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-arranged relation with regards to the first world locking equipment, about the full 360° circumference of the ring gear. The 1st and second planet gears rotate with the ring gear and in addition rotate about their very own respective mounting axes while engaging the set and result spur gear tooth. In the absence of rotation of the ring gear, any rotational drive applied to the output spur equipment will push the fixed and result spur gear tooth to lock the initial 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 otherwise include a sprocket in meshing engagement with a timing chain. The principal motor input may or else add a sprocket in meshing engagement with a plurality of timing gears.
Each seal of the ring plate and seal configuration could 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 result spur gear. The pressure angle 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 ideally end up being about 35 degrees. The parts of the gearbox could be made from metal, plastic-type, composite, ceramic, wood, plywood, metallic powder, or combinations thereof.
Extra objects, advantages and novel top features of today's invention will be established partly in the description which follows, and can in part become obvious 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 small tooth business lead angle of the worm and thus an efficiency of η ≤ 0,5 with worm driving. Consequently self-locking gear models are usually uneconomical when high self locking gearbox performances and long operating times are needed. A worm equipment unit is considered self-locking at standstill if, with worm wheel driving, beginning with standstill is unattainable. This is actually the case with ATLANTA wheel sets and gear products when the lead position can be <5°. A worm gear unit is considered self-locking from the working condition if the apparatus unit involves a standstill whilst getting backdriven. That is only feasible 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 locking mechanism. To avoid overstressing of the worm gear drive due to the high kinetic energy involved, you should furthermore allow for a certain running-down time after stopping the input.
