Reliable, self-locking drive for ventilation and display installations
Ventilation and screening are two of the most important basic strategies that growers use every day to maintain the ideal climate and achieve optimum crop yields. It really is critically very important to growers to be able to open up, close and modify air vents and environment screens at any moment and with a high degree of precision. Growers depend on these systems to are they should, and depend on the drive systems that control their screens and air vents.
In order to guarantee the dependability of ventilation and display screen installations, Ever-Power introduced the EP engine gearbox – a compact and highly dependable self-locking drive that has been developed specifically for use in horticulture. The Ever-Power EP is now the standard when it comes to drive technology for cup greenhouses, and includes a well-earned reputation for reliability, long assistance life and versatility.

2. The apparatus system of claim 1 further comprising a second planet locking equipment rotatably mounted within stated ring gear in 180° off-set relation with regards to the first world locking gear, about the full 360° circumference of the ring gear, whereby said initial and second world gears rotate with stated ring gear and in addition rotate about their very own respective installation axes while engaging stated fixed and result spur gear teeth, and whereby in the lack of rotation of the band gear a rotational drive put on said output spur equipment will power said fixed and output spur gear tooth to lock said first and second planet gears in place.
With reference to the use of the inventive gear system discussed herein, the machine provides a simple and low-cost self-lubricating gearbox which can be driven in a forward and invert direction via an input motor shaft, but can’t be back-driven through its output gearing. By virtue of its configuration as a band gear, the invention could be effectively built-into any rotating machinery which utilizes a winch/drum. As such, these inventive gear systems have particular software in the field of 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, but not drop the strain. These inventive equipment systems can also be put on 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 superior to existing configurations made up of friction brakes and worm drive gearboxes. The integrated advantages of a planetary type equipment train further enable a compact assembly. The system’s hollow through the center output spur shaft can move wiring to a rotating connection, as well as the simple insertion of downstream equipment shafts. This would 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 in certain settings (such as for example during theatrical performances) and burdensome maintenance through the schedule lubrication of the machine gears.
To address such drawbacks, briefly described, the self-locking, non-backdrivable gear program of today’s invention comprises a principal motor input and self-lubricating gear box. 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 gear, fixed spur gear, and output spur equipment. The input ring gear is mounted around the driveshaft and situated in meshing engagement with the primary motor input. The ring plate and seal configuration are mounted to the ring gear and seal the elements within the ring equipment 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 band gear, whereby the planet equipment rotates with the band gear and also rotates about its own mounting axis. The output spur equipment is rotatably mounted within the ring gear, in a radially inward, concentric regards to the ring gear, and additional includes an result shaft adapted for installation to the drive shaft. The output spur equipment has N+/−X amount of gear teeth in meshing engagement with the earth equipment. The fixed spur equipment is fixedly mounted around the result shaft and positioned adjacent to the result spur gear. The fixed spur equipment has N amount of gear the teeth in meshing engagement with the earth gear teeth. The fixed and output spur gears have substantially similar diameters to allow the fixed and output spur gear teeth to substantially align while engaging with the planet equipment. The fixed and result spur gear the teeth each comprise a noise-dampening pressure angle configuration to angularly compliment the planet gear teeth.
In operation, rotation of the primary electric motor 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 causes rotation of the drive shaft. Nevertheless, in the absence of rotation of the ring gear, any rotational push put on the output spur gear (e.g., via the output shaft) will drive the substantially aligned fixed and result gear the teeth to lock the planet locking gear in place.
Additional aspects of the system are provided herein. For example, within an embodiment of the system having two planet locking gears, the second planet locking gear could be rotatably installed within the ring gear in a 180° off-founded relation with regards to the first world locking equipment, about the entire 360° circumference of the ring gear. The first and second world gears rotate with the band gear and in addition rotate about their very own respective mounting axes while engaging the fixed and result spur gear the teeth. In the absence of rotation of the band gear, any rotational drive applied to the output spur equipment will push the fixed and result spur gear the teeth to lock the 1st and second world gears in place.
The primary motor input may include a sprocket in meshing engagement with a timing belt. The primary motor input may otherwise include a sprocket in meshing engagement with a timing chain. The primary motor input may or else 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 further 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 position configuration may more ideally be from about 40 degrees to 30 degrees. The pressure position configuration may most preferably end up being about 35 degrees. The components of the gearbox may be made from metal, plastic-type material, composite, ceramic, wooden, plywood, metal powder, or combinations thereof.
Extra objects, advantages and novel features of today’s invention will be set forth in part in the description which follows, and can in part become apparent to those in the practice of the invention, when regarded with the self locking gearbox attached figures.

Self-locking property of Worm Gear Units
A precondition for the self-locking quality of equipment units is a little tooth business lead angle of the worm and thus an efficiency of η ≤ 0,5 with worm traveling. Consequently self-locking gear models are generally uneconomical when high performances and lengthy operating times are needed. A worm gear unit is known as self-locking at standstill if, with worm wheel traveling, beginning with standstill is impossible. This is actually the case with ATLANTA wheel pieces and gear devices when the lead position is <5°. A worm gear unit is considered self-locking from the operating condition if the gear unit comes to a standstill whilst getting backdriven. This is only feasible with high gear ratios and incredibly 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. To avoid overstressing of the worm gear drive due to the very high kinetic energy involved, you should furthermore allow for a certain running-down period after stopping the insight.
