self locking gearbox

Reliable, self-locking drive for ventilation and self locking gearbox display screen installations
Ventilation and screening are two of the most important simple strategies that growers use each day to maintain the perfect climate and achieve maximum crop yields. It is critically important for growers in order to open, close and change air vents and environment screens at any moment and with a higher degree of precision. Growers rely on these systems to are they should, and depend on the drive systems that control their screens and air vents.
To assure the dependability of ventilation and display installations, Ever-Power introduced the EP electric motor gearbox – a compact and highly dependable self-locking drive that is developed particularly for use in horticulture. The Ever-Power EP is now the standard with regards to drive technology for cup greenhouses, and includes a well-earned status for reliability, long support life and versatility.

2. The apparatus system of claim 1 further comprising another planet locking equipment rotatably mounted within said ring equipment in 180° off-established relation with regards to the first world locking gear, about the full 360° circumference of the ring equipment, whereby said first and second planet gears rotate with said ring gear and also rotate about their very own respective mounting axes while engaging stated fixed and result spur gear the teeth, and whereby in the absence of rotation of the band gear a rotational push applied to said output spur gear will push said fixed and output spur gear tooth to lock said initial 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 which can be driven in a forward and invert 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 this kind of, these inventive gear systems have particular application 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 in a position to wind in both a clockwise and counterclockwise direction, however, not drop the load. These inventive equipment systems can also be put on 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 superior to existing configurations produced up of friction brakes and worm drive gearboxes. The built-in benefits of a planetary type gear train further enable a compact assembly. The system’s hollow through the center output spur shaft can pass wiring through to a rotating connection, as well as the simple insertion of downstream apparatus 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 system moreover addresses certain disadvantages of similar existing gear systems, e.g., vibration and noise conditions 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 major motor input and self-lubricating gear package. The primary motor insight can be 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 gear, fixed spur equipment, and output spur equipment. The input ring equipment 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 elements within the ring equipment so as to permit the internal self-lubrication of the gearbox through a volume 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 mounting axis. The output spur equipment is rotatably mounted within the ring gear, in a radially inward, concentric relation to the ring gear, and additional includes an output shaft adapted for installation to the drive shaft. The output spur equipment has N+/−X number of gear teeth in meshing engagement with the earth gear. The fixed spur gear is fixedly installed around the result shaft and positioned adjacent to the output spur gear. The fixed spur equipment has N quantity of gear the teeth in meshing engagement with the earth gear tooth. The fixed and output spur gears have substantially similar diameters to allow the fixed and output spur gear the teeth to substantially align while engaging with the planet gear. The fixed and result spur gear tooth each comprise a noise-dampening pressure angle configuration to angularly compliment the planet gear teeth.
Functioning, rotation of the principal electric motor input causes rotation of the band 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. Nevertheless, in the absence of rotation of the ring gear, any rotational drive put on the output spur gear (electronic.g., via the result shaft) will force the considerably aligned fixed and result gear the teeth to lock the earth locking gear set up.
Various other aspects of the system are provided herein. For example, in an embodiment of the system having two planet locking gears, the second planet locking gear could be rotatably installed within the band gear in a 180° off-set relation with respect to the first planet locking gear, about the entire 360° circumference of the ring gear. The 1st and second world gears rotate with the ring gear and in addition rotate about their personal respective installation axes while engaging the set and result spur gear the teeth. In the absence of rotation of the ring gear, any rotational power put on the output spur gear will power the fixed and output spur gear the teeth to lock the first and second world gears in place.
The primary 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 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 may be an O-ring or shaft seal. The gearbox may further comprise a ball bearing band positioned on the result shaft to facilitate rotation of the output spur gear. 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 components of the gearbox may be made from metal, plastic, composite, ceramic, wooden, plywood, steel 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 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 lead angle of the worm and thus an efficiency of η ≤ 0,5 with worm traveling. Consequently self-locking gear systems are usually uneconomical when high performances and long operating times are needed. A worm equipment unit is known as self-locking at standstill if, with worm wheel traveling, starting from standstill is not possible. This is the case with ATLANTA wheel sets and gear products when the lead position is definitely <5°. A worm gear unit is considered self-locking from the running condition if the gear unit comes to a standstill whilst being backdriven. That is only feasible with high equipment ratios and very low speeds. Shocks and vibrations can neutralize the self-locking capacity! For that reason a self-locking tooth program cannot replace a brake or reverse-stroke fasten. In order to avoid overstressing of the worm gear drive because of the very high kinetic energy included, you should furthermore enable a certain running-down time after stopping the input.
