A self-locking non-backdrivable gear program, comprising: a. a principal motor input adapted for rotation of a self-lubricating gearbox about the axis of a drive shaft; b. said gearbox comprises: i. an insight ring gear mounted around said driveshaft and situated in meshing engagement with said primary motor insight; ii. a ring plate and seal configuration installed to said ring gear for sealing parts within said ring equipment to allow the inner self-lubrication of said gearbox through a level of lubricant; iii. a planet locking equipment rotatably mounted within said ring gear, whereby said planet gear rotates with said ring equipment and in addition rotates about its own mounting axis; iv. an output spur gear rotatably mounted within stated ring equipment in a radially inward, concentric relation to said ring gear and additional includes an result shaft adapted for mounting to stated drive shaft, said output spur equipment has N +/−X amount of gear the teeth in meshing engagement with stated planet gear; v. a set spur equipment fixedly mounted around stated result shaft and positioned adjacent to said result spur equipment, said fixed spur gear has N amount of gear the teeth in meshing engagement with stated planet gear; and vi. wherein stated fixed and output spur gears have substantially similar diameters to permit said fixed and result spur gear teeth to considerably align while engaging with stated planet gear, vii. wherein said fixed and result spur gear the teeth comprise a noise-dampening pressure position configuration which angularly compliment stated planet gear teeth, viii. whereby rotation of said primary motor insight causes rotation of said ring gear which causes rotation of said planet gear which in turn causes rotation of stated output spur gear which in turn causes rotation of stated drive shaft, and whereby in the lack of rotation of said ring gear a rotational push applied to said output spur gear forces the substantially aligned said fixed and result gear the teeth to lock said world locking gear in place.
2. The gear system of claim 1 further comprising another planet locking gear rotatably mounted within stated ring gear in 180° off-arranged relation with respect to the first planet locking equipment, about the entire 360° circumference of the ring equipment, whereby said first and second planet gears rotate with said ring gear and also rotate about their own respective installation axes while engaging stated fixed and result spur gear tooth, and whereby in the absence of rotation of the band gear a rotational force applied to said output spur gear will force 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 provides a simple and low-cost self-lubricating gearbox that can be driven in a forward and reverse direction through an input engine shaft, but cannot 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 such, these inventive equipment systems have particular app 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 should be in a position to wind in both a clockwise and counterclockwise direction, but not drop the load. These inventive gear 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 more advanced than existing configurations produced up of friction brakes and worm drive gearboxes. The included advantages of a planetary type equipment train further allow for a concise assembly. The system’s hollow through the guts result spur shaft can pass wiring to a rotating connection, along with the basic insertion of downstream gear shafts. This might be especially useful for cable drums winding electrified cable, and turntables with electrics/electronic devices up to speed, for example.
The inventive gear system 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 system gears.
To address such disadvantages, briefly described, the self-locking, non-backdrivable gear system of the present invention comprises a main motor input and self-lubricating gear package. The primary motor input 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 equipment, fixed spur gear, and output spur gear. 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 components within the ring gear so as to permit 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 gear rotates with the ring gear and in addition rotates about its own mounting axis. The output 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 number of gear tooth in meshing engagement with the planet equipment. The fixed spur equipment is fixedly mounted around the output shaft and positioned next to the result spur equipment. The fixed spur equipment has N number of gear teeth in meshing engagement with the earth gear tooth. The fixed and result spur gears have considerably similar diameters to permit the fixed and result spur gear teeth to substantially align while engaging with the earth gear. 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 principal motor input causes rotation of the ring gear which 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 drive put on the output spur equipment (electronic.g., via the output shaft) will pressure the considerably aligned fixed and output gear teeth to lock the earth locking gear in place.
Various other aspects of the system are provided herein. For instance, in an embodiment of the machine having two world locking gears, the next planet locking gear may be rotatably installed within the ring gear in a 180° off-set relation with respect to the first planet locking gear, about the full 360° circumference of the ring gear. The 1st and second world gears rotate with the ring gear and also rotate about their own respective installation axes while engaging the set and output spur gear teeth. In the lack of rotation of the band gear, any rotational pressure put on the output spur gear will drive the fixed and result spur gear the teeth 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 add 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 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 output shaft to facilitate rotation of the result spur equipment. The pressure angle configuration could 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 end up being about 35 degrees. The parts of the gearbox could be made from metal, plastic, composite, ceramic, wood, plywood, metallic powder, or combinations thereof.
Additional objects, advantages and novel features of the present invention will be established partly in the description which follows, and will 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 driving. Consequently self-locking gear products are generally uneconomical when high performances and long operating times are required. A worm gear unit is considered self-locking at standstill if, with worm wheel driving, starting from standstill is not possible. This is the case with ATLANTA wheel sets and gear systems when the lead position is usually <5°. A worm gear unit is known as self-locking from the working condition if the gear unit involves a standstill whilst being backdriven. That is only feasible with high gear ratios and very low speeds. Shocks and vibrations can neutralize the self-locking capacity! Therefore 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 high kinetic energy included, you should furthermore enable a certain running-down period after stopping the insight.
