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 first and second world gears rotate with stated ring gear and in addition 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 band gear a rotational push put on said output spur equipment will pressure said fixed and result 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 provides a simple and low-cost self-lubricating gearbox which can be driven in a forward and reverse direction via an input engine shaft, but cannot be back-driven through its output gearing. By virtue of its configuration as a ring gear, the self locking gearbox invention could be effectively integrated into any rotating machinery which utilizes a winch/drum. As this kind of, these inventive gear systems have particular program 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 able 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 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 more advanced than existing configurations made up of friction brakes and worm drive gearboxes. The built-in benefits 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 through to a rotating connection, and also the basic insertion of downstream tools shafts. This would be particularly useful for cable drums winding electrified cable, and turntables with electrics/electronics on board, for example.
The inventive gear system moreover addresses certain disadvantages 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 drawbacks, briefly described, the self-locking, non-backdrivable gear system of the present invention comprises a major motor input and self-lubricating gear package. The primary motor insight is usually 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 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 elements within the ring gear so as to permit 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 planet gear rotates with the ring gear and also rotates about its own mounting axis. The result spur gear is rotatably installed within the ring equipment, in a radially inward, concentric regards to the ring equipment, and further includes an output shaft adapted for installation to the drive shaft. The output spur equipment has N+/−X amount of gear tooth in meshing engagement with the planet equipment. The fixed spur equipment is fixedly installed around the result shaft and positioned next to the output spur equipment. The fixed spur equipment has N quantity of gear tooth in meshing engagement with the planet gear tooth. The fixed and output spur gears have substantially similar diameters to allow the fixed and result spur gear tooth to substantially align while engaging with the planet gear. The fixed and result spur gear tooth each comprise a noise-dampening pressure position configuration to angularly compliment the planet gear teeth.
Functioning, rotation of the principal engine input causes rotation of the ring gear which in turn causes rotation of the earth gear which causes rotation of the output spur gear which in turn causes rotation of the drive shaft. Nevertheless, in the lack of rotation of the band gear, any rotational pressure applied to the output spur equipment (electronic.g., via the output shaft) will push 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 example, 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 respect to the first world locking gear, about the full 360° circumference of the ring gear. The first and second planet gears rotate with the ring gear and in addition rotate about their own respective installation axes while engaging the set and output spur gear teeth. In the absence of rotation of the band gear, any rotational power put on the output spur equipment will drive the fixed and result spur gear tooth to lock the 1st and second planet gears in place.
The primary motor input may 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 principal motor input may otherwise include a sprocket in meshing engagement with a plurality of timing gears.
Each seal of the ring plate and seal configuration could be an O-band 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 angle configuration could 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 angle configuration may most ideally be about 35 degrees. The components of the gearbox could be made from metal, plastic material, composite, ceramic, wooden, plywood, metallic powder, or combinations thereof.
Extra objects, advantages and novel features of today’s 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 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 therefore an efficiency of η ≤ 0,5 with worm driving. Consequently self-locking gear models are usually uneconomical when high performances and long operating times are required. A worm gear unit is known as self-locking at standstill if, with worm wheel driving, beginning with standstill is extremely hard. This is the case with ATLANTA wheel units and gear devices when the lead angle is definitely <5°. A worm gear unit is considered self-locking from the operating condition if the apparatus unit comes to a standstill whilst getting backdriven. This is only possible with high gear ratios and very 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. In order to avoid overstressing of the worm gear drive because of the high kinetic energy involved, you should furthermore allow for a certain running-down time after stopping the insight.
