Reliable, self-locking drive for ventilation and screen installations
Ventilation and screening are two of the most important basic strategies that growers make use of every day to maintain the perfect climate and achieve maximum crop yields. It is critically important for growers in order to open, close and adjust air vents and weather screens at at any time and with a high degree of accuracy. Growers depend on these systems to are they should, and rely on the drive systems that control their displays and air vents.
To assure the dependability of ventilation and screen installations, Ever-Power introduced the EP electric motor gearbox – a compact and highly dependable self-locking drive that has been developed particularly for use in horticulture. The Ever-Power EP is now the standard when it comes to drive technology for glass greenhouses, and includes a well-earned status for reliability, long provider life and versatility.

2. The apparatus system of claim 1 further comprising another planet locking equipment rotatably mounted within stated ring equipment in 180° off-established relation with respect to the first world locking equipment, about the full 360° circumference of the ring equipment, whereby said initial and second world gears rotate with said ring gear and in addition rotate about their personal respective mounting axes while engaging said fixed and result spur gear teeth, and whereby in the absence of rotation of the band gear a rotational force applied to said output spur equipment will drive said fixed and result spur gear the teeth to lock said first and second planet gears in place.
With reference to the use 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 invert direction via an input motor shaft, but cannot be back-driven through its output gearing. By virtue of its configuration as a band gear, the invention could be effectively integrated into any rotating machinery which utilizes a winch/drum. As such, these inventive equipment systems have particular software 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 able to wind in both a clockwise and counterclockwise direction, but not drop the load. These inventive equipment systems can also be applied to move scenery, create results, 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 made up of friction brakes and worm drive gearboxes. The included advantages of a planetary type equipment train further allow for a compact assembly. The system’s hollow through the center output spur shaft can pass wiring through to a rotating connection, and also the simple insertion of downstream tools shafts. This would be especially useful for cable drums winding electrified cable, and turntables with electrics/electronics on board, for example.
The inventive gear system moreover addresses certain drawbacks of similar existing equipment systems, e.g., vibration and noise issues that are unacceptable using settings (such as during theatrical performances) and burdensome maintenance through the program 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 insight and self-lubricating gear box. The primary motor input is adapted for rotation of the gearbox about the axis of a drive shaft. The gearbox comprises an insight ring gear, ring plate and seal configuration, planet locking equipment, fixed spur equipment, and output spur gear. The input ring equipment is mounted around the driveshaft and situated in meshing engagement with the primary motor input. The band 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 volume of lubricant.
One or more world locking gears is rotatably mounted within the band gear, whereby the earth gear rotates with the ring gear and also 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 equipment, and further includes an result shaft adapted for mounting to the drive shaft. The output spur equipment has N+/−X amount of gear tooth in meshing engagement with the earth equipment. The fixed spur equipment is fixedly installed around the output shaft and positioned adjacent to the output spur equipment. The fixed spur gear has N number of gear tooth in meshing engagement with the earth gear tooth. The fixed and output spur gears have considerably similar diameters to allow the fixed and output spur gear the teeth to substantially align while engaging with the planet equipment. The fixed and output spur gear tooth each comprise a noise-dampening pressure position configuration to angularly compliment the earth gear teeth.
In operation, rotation of the principal engine input causes rotation of the ring gear which in turn causes rotation of the planet gear which 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 pressure put on the output spur gear (electronic.g., via the output shaft) will drive the considerably aligned fixed and output gear tooth to lock the planet locking gear set up.
Various other aspects of the system are provided herein. For example, within an embodiment of the system having two world locking gears, the second planet locking gear could be rotatably mounted within the band gear in a 180° off-set relation with regards to the first planet locking gear, about the full 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 installation axes while engaging the fixed and result spur gear tooth. In the absence of rotation of the ring gear, any rotational push put on the output spur equipment will drive the fixed and result spur gear teeth to lock the 1st and second planet gears in place.
The primary 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 include 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 band positioned on the output shaft to facilitate rotation of the output spur equipment. The pressure angle configuration could be from about 45 degrees to about 25 degrees. The pressure angle configuration may more ideally be from about 40 degrees to 30 degrees. The pressure angle configuration may most ideally end up being about 35 degrees. The elements of the gearbox may be made from metal, plastic-type material, composite, ceramic, wood, plywood, steel powder, or combinations thereof.
Additional objects, advantages and novel features of the present invention will be set forth partly in the description which follows, and will in part become apparent 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 little tooth business lead angle of the worm and therefore an efficiency of η ≤ 0,5 with worm generating. Consequently self-locking gear models are generally uneconomical when high performances and lengthy operating times are required. A worm equipment unit is considered self-locking at standstill if, with worm wheel traveling, beginning with standstill is difficult. This is the case with ATLANTA wheel pieces and gear systems when the lead angle is <5°. A worm gear unit is known as self-locking from the running condition if the gear unit involves a standstill whilst becoming backdriven. That is only possible with high gear ratios and very low speeds. Shocks and vibrations can neutralize the self-locking capacity! As a result a self-locking tooth program cannot replace a brake or reverse-stroke locking mechanism. To avoid overstressing of the worm gear drive because of the very high kinetic energy involved, you should furthermore enable a certain running-down period after stopping the insight.
