self locking gearbox

Reliable, self-locking drive for ventilation and screen installations
Ventilation and screening are two of the most crucial simple strategies that growers make use of each day to maintain the perfect climate and achieve optimum crop yields. It really is critically important for growers in order to open up, close and modify air vents and climate screens at at any time and with a high degree of accuracy. Growers rely on these systems to work as they should, and depend on the drive systems that control their screens and air vents.
To assure the dependability of ventilation and screen installations, Ever-Power introduced the EP electric motor gearbox – a concise 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 glass greenhouses, and has a well-earned reputation for reliability, long services life and versatility.

2. The gear system of claim 1 further comprising another planet locking gear rotatably mounted within said ring equipment in 180° off-arranged relation with respect to the first planet 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 stated fixed and result spur gear tooth, and whereby in the absence of rotation of the ring gear a rotational force put on said output spur equipment will force said fixed and result spur gear teeth to lock said 1st and second planet gears in place.
With reference to the application of the inventive gear system discussed herein, the machine provides a simple and low-cost self-lubricating gearbox that 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 band gear, the 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 isn’t 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 gear systems can also be put on move scenery, create effects, 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 more advanced than existing configurations produced 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 complete wiring through to a rotating connection, along with the basic insertion of downstream devices shafts. This might be particularly useful for cable drums winding electrified cable, and turntables with electrics/consumer electronics on board, for example.
The inventive gear program moreover addresses certain disadvantages of similar existing equipment systems, e.g., vibration and noise conditions that are unacceptable using settings (such as for example during theatrical performances) and burdensome maintenance through the regimen lubrication of the system gears.
To address such disadvantages, briefly described, the self-locking, non-backdrivable gear program of today’s invention comprises a primary motor insight and self-lubricating gear box. The primary motor input can be adapted for rotation of the gearbox about the axis of a drive shaft. The gearbox comprises an input ring gear, band plate and seal configuration, planet locking gear, fixed spur equipment, and output spur gear. The input ring equipment is installed 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 components within the ring gear so as to allow the internal self-lubrication of the gearbox through a level of lubricant.
One or more world locking gears is rotatably mounted within the ring gear, whereby the planet gear rotates with the band gear and in addition rotates about its own mounting axis. The output spur equipment is rotatably mounted within the ring equipment, in a radially inward, concentric relation to the ring gear, and additional includes an output shaft adapted for mounting to the drive shaft. The output spur equipment has N+/−X number of gear the teeth in meshing engagement with the earth equipment. The fixed spur gear is fixedly installed around the result shaft and positioned next to the result spur gear. The fixed spur equipment has N quantity of gear tooth in meshing engagement with the earth gear teeth. The fixed and result spur gears have considerably similar diameters to allow the fixed and result spur gear the teeth to substantially align while engaging with the planet equipment. The fixed and output spur gear the teeth each comprise a noise-dampening pressure position configuration to angularly compliment the planet gear teeth.
Functioning, rotation of the primary 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 causes rotation of the drive shaft. Nevertheless, in the absence of rotation of the band gear, any rotational pressure applied to the output spur equipment (e.g., via the result shaft) will pressure the substantially aligned fixed and result gear the teeth to lock the planet locking gear set up.
Additional aspects of the machine are provided herein. For instance, within an embodiment of the system having two planet locking gears, the second planet locking gear may be rotatably installed within the band gear in a 180° off-set relation with respect to the first planet locking gear, about the full 360° circumference of the ring gear. The 1st and second world gears rotate with the band gear and also rotate about their very own respective installation axes while engaging the set and output spur gear teeth. In the absence of rotation of the ring gear, any rotational power put on the output spur equipment will push the fixed and output 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 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 band plate and seal configuration could be an O-ring or shaft seal. The gearbox may additional comprise a ball bearing ring positioned on the result shaft to facilitate rotation of the output spur equipment. 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 angle configuration may most ideally become about 35 degrees. The parts of the gearbox could be made from metal, plastic-type, composite, ceramic, wooden, 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 obvious to those in the practice of the invention, when regarded 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 therefore an efficiency of η ≤ 0,5 with worm driving. Consequently self-locking gear products are generally uneconomical when high performances and long operating times are necessary. A worm gear unit is considered self-locking at standstill if, with worm wheel driving, beginning with standstill is not possible. This is the case with ATLANTA wheel models and gear systems when the lead angle is certainly <5°. A worm gear unit is considered self-locking from the operating condition if the apparatus unit involves 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! Therefore a self-locking tooth program cannot replace a brake or reverse-stroke fasten. In order to avoid overstressing of the worm gear drive due to the high kinetic energy included, you should furthermore enable a certain running-down period after stopping the insight.
