planetary gear motor

Ever-Power DC Planetary gearmotors are an inline option for low speed, high torque, and/or adjustable load requirements. These equipment motors are designed for intermittent duty operation for the reason that planetary gearbox construction provides the highest effectiveness and best output torque of all our quickness reducers. DC motors combined with planetary equipment reducers are well suited for tools in the agricultural and construction industrial sectors. With 18 ratio choices ranging from 5:1 to 1000:1, we’ve a DC planetary gearmotor answer to fit your needs.
For a smaller footprint and quieter gearbox design, look for our I-series Planetary gearmotors. Frame sizes 52cm, 62cm, and 81cm, 12 ratios which range from 5:1 to 308:1.
1/25 to 3/8 HP
12, 24, 90, 130, 180VDC, 115 FWR
.5 – 475 RPM
3.5 – 950 in-lb rated torque
Frame Size 60, 80, 108 mm
5:1 – 1000:1 standard ratios
Typical brush life of 2000+ hours (varies by application)
This is a straightforward ~140RPM (no load), DC planetary gearmotor. This electric motor is great for numerous applications such as for example robotics, electric locks, household automation, and tiny actuators.
The supply voltage range is 6VDC – 24VDC with the polarity marker at the base of the engine. The planetary gear box, mounted on top of the motor casing, gives this motor a relatively large stall torque because of its size. The overall body of the engine is constructed of metal, apart from the set of world gears on the first input gear set, which will be plastic.
This planetary gearmotor comes with an over-all body dimension of 76.1mm length with a 22mm diameter while the travel shaft is 12mm in length and 6mm in diameter.
Benefits of using planetary gear motors in work
There are lots of types of geared motors that can be used in search for an ideal movement in an engineering project. Taking into account the technical specs, the required performance or space restrictions of our design, you should ask yourself to use one or the various other. In this post we will delve on the planetary equipment motors or epicyclical gear, and that means you will know completely what its advantages are and find out some successful applications.
The planetary gear models are seen as a having gears whose disposition is quite different from other models such as the uncrowned end, cyclical (step-by-step) or spur and helical gears. How could we classify their elements?
Sun: The central gear. It has a bigger size and rotates on the central axis.
The earth carrier: Its objective is to carry up to 3 gears of the same size, which mesh with the sun gear.
Crown or ring: an outer ring (with teeth in its inner part) meshes with the satellites possesses the whole epicyclical train. In addition, the core can also become a middle of rotation for the outer ring, allowing it to easily change directions.
For accuracy and stability, many automated transmissions currently use planetary gear motors. If we talk about sectors this reducer gives great flexibility and can be used in very different applications. Its cylindrical condition is easily adaptable to thousands of spaces, ensuring a large reduction in an extremely contained space.
Regularly this sort of drives can be utilised in applications that require higher levels of precision. For example: Industrial automation equipment, vending machines or robotics.
What are the primary features of planetary gear motors?
Increased repeatability: Its greater speed radial and axial load offers reliability and robustness, minimizing the misalignment of the gear. In addition, uniform transmitting and low vibrations at several loads give a perfect repeatability.
Best precision: Most rotating angular stability boosts the accuracy and stability of the movement.
Lower noise level because there is more surface contact. Rolling is much softer and jumps are virtually nonexistent.
Greater durability: Due to its torsional rigidity and better rolling. To improve this characteristic, your bearings lessen the losses that could take place by rubbing the shaft on the box directly. Thus, greater effectiveness of the gear and a very much smoother procedure is achieved.
Very good degrees of efficiency: Planetary reducers deliver greater efficiency and because of its design and internal layout losses are minimized planetary gear motor throughout their work. Actually, today, this type of drive mechanisms happen to be those that provide greater efficiency.
Increased torque transmission: With an increase of teeth in contact, the mechanism is able to transmit and withstand even more torque. In addition, it does it in a far more uniform manner.
Maximum versatility: The mechanism is contained in a cylindrical gearbox, that can be installed in almost any space.
What regulations connect with planetary gearboxes?
Take into account that each supplier sets its own methods when presenting the operating time of the gears or the maximum torque they are able to bear. Nevertheless, we are able to find certain regulations governing these parameters.
– ISO 6636 for gears.
– DIN ISO 281: With the guidelines that helps to make a correct calculation of the bearings.
– ISO 9409: Part II talks about the design of the output shafts of the geared motors according to several specifications.
