self locking gearbox

Reliable, self-locking drive for ventilation and display screen installations
Ventilation and screening are two of the most crucial simple strategies that growers make use of each day to maintain the ideal climate and achieve maximum crop yields. It is critically very important to growers in order to open, close and change air vents and climate screens at at any time and with a higher degree of precision. Growers rely on these systems to work as they should, and rely 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 engine gearbox – a concise and highly dependable self-locking drive that has been developed specifically for use in horticulture. The Ever-Power EP is now the standard with regards to drive technology for glass greenhouses, and has a well-earned status for reliability, long assistance life and versatility.

2. The apparatus system of claim 1 further comprising a self locking gearbox second planet locking equipment rotatably mounted within said ring equipment in 180° off-set relation with respect to the first planet locking gear, about the full 360° circumference of the ring equipment, whereby said first and second planet gears rotate with stated ring gear and in addition rotate about their very own respective mounting axes while engaging said fixed and output spur gear tooth, and whereby in the lack of rotation of the ring gear a rotational force put on said output spur equipment will pressure said fixed and output spur gear the teeth to lock said initial 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 that can be driven in a forward and reverse direction through an input motor shaft, but cannot be back-driven through its output gearing. By virtue of its configuration as a band gear, the invention can be effectively integrated 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 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 equipment 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 superior to existing configurations made up of friction brakes and worm drive gearboxes. The integrated advantages of a planetary type equipment train further allow for a concise assembly. The system’s hollow through the guts result spur shaft can move wiring through to a rotating connection, along with the simple insertion of downstream gear shafts. This would be especially useful for cable drums winding electrified cable, and turntables with electrics/consumer electronics up to speed, for example.
The inventive gear program moreover addresses certain disadvantages of similar existing equipment systems, e.g., vibration and noise conditions that are unacceptable in certain settings (such as during theatrical performances) and burdensome maintenance through the program lubrication of the machine gears.
To address such disadvantages, briefly described, the self-locking, non-backdrivable gear system of the present invention comprises a primary motor insight and self-lubricating gear container. The primary motor insight can be 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 equipment, and output spur equipment. The input ring equipment is installed around the driveshaft and situated in meshing engagement with the primary motor input. The ring plate and seal configuration are mounted to the ring equipment and seal the parts within the ring gear 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 gear rotates with the band gear and in addition rotates about its own mounting axis. The result spur equipment is rotatably installed within the ring equipment, in a radially inward, concentric regards to the ring equipment, and additional includes an output shaft adapted for mounting 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 equipment is fixedly mounted around the output shaft and positioned next to the result spur equipment. The fixed spur gear has N amount of gear the teeth in meshing engagement with the planet gear tooth. The fixed and output spur gears have substantially similar diameters to allow the fixed and output spur gear tooth to considerably align while engaging with the planet gear. The fixed and output spur gear tooth each comprise a noise-dampening pressure angle configuration to angularly compliment the earth gear teeth.
In operation, rotation of the principal motor input causes rotation of the ring gear which causes rotation of the planet gear which in turn 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 power put on the output spur equipment (e.g., via the result shaft) will push the considerably aligned fixed and result gear the teeth to lock the earth locking gear in place.
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 could be rotatably mounted within the ring gear in a 180° off-set up relation with regards to the first world locking gear, about the entire 360° circumference of the ring gear. The 1st and second planet gears rotate with the band gear and in addition rotate about their very own respective installation axes while engaging the set and output spur gear the teeth. In the lack of rotation of the band gear, any rotational force applied to the output spur equipment will drive the fixed and output spur gear teeth to lock the first and second planet gears in place.
The principal 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 principal motor input may or else 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-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 gear. The pressure angle configuration may 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 position configuration may most ideally become about 35 degrees. The elements of the gearbox could be made from metal, plastic, composite, ceramic, wood, plywood, metal powder, or combinations thereof.
Additional objects, advantages and novel top features of today’s invention will be established in part in the description which follows, and will 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 equipment units is a little tooth lead angle of the worm and thus an efficiency of η ≤ 0,5 with worm generating. Consequently self-locking gear systems are usually 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 impossible. This is the case with ATLANTA wheel models and gear units when the lead angle is definitely <5°. A worm gear unit is considered self-locking from the running 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! As a result 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 very high kinetic energy involved, you should furthermore allow for a certain running-down period after stopping the insight.
