planetary gear motor

Ever-Vitality DC Planetary gearmotors are an inline alternative for low speed, substantial torque, and/or variable load requirements. These gear motors are created for intermittent duty operation because the planetary gearbox construction provides the highest efficiency and best outcome planetary gear motor torque of all our quickness reducers. DC motors combined with planetary gear reducers are perfect for gear in the agricultural and development industries. With 18 ratio alternatives which range from 5:1 to 1000:1, we have a DC planetary gearmotor answer to suit 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
Normal brush life of 2000+ hours (varies by application)
This is a simple ~140RPM (no load), DC planetary gearmotor. This motor is great for several applications such as robotics, electric locks, home automation, and small actuators.
The supply voltage range is 6VDC – 24VDC with the polarity marker at the base of the electric motor. The planetary gear package, mounted on top of the motor housing, gives this engine a relatively large stall torque for its size. The overall body of the engine is made from metal, apart from the set of planet gears on the primary input equipment set, which happen to be plastic.
This planetary gearmotor has an over all body dimension of 76.1mm length with a 22mm diameter while the travel shaft is 12mm long and 6mm in diameter.
Advantages of using planetary gear motors in your projects
There are plenty of types of geared motors that can be used in search for the perfect movement within an engineering project. Taking into account the technical specifications, the mandatory performance or space restrictions of our style, you should consider to work with one or the various other. In the following paragraphs we will delve on the planetary gear motors or epicyclical gear, so you will know completely what its advantages are and find out some successful applications.
The planetary gear products 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 equipment. 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 band: an outer band (with teeth on its inner part) meshes with the satellites possesses the whole epicyclical train. In addition, the core may also become a center of rotation for the outer ring, and can easily change directions.
For accuracy and reliability, many programmed transmissions currently use planetary gear motors. If we discuss sectors this reducer presents great flexibility and works extremely well in completely different applications. Its cylindrical condition is without difficulty adaptable to an infinite number of places, ensuring a large reduction in a very contained space.
Regularly this sort of drives can be used in applications that want higher degrees of precision. For example: Industrial automation equipment, vending machines or robotics.
What are the primary benefits 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 different loads provide a perfect repeatability.
Ideal precision: Most rotating angular stability improves the accuracy and stability of the movement.
Lower noise level since there is more area contact. Rolling is a lot softer and jumps are virtually nonexistent.
Greater durability: Due to its torsional rigidity and better rolling. To boost this characteristic, your bearings help reduce the losses that could take place by rubbing the shaft on the field directly. Thus, greater proficiency of the apparatus and a very much smoother operation is achieved.
Very good degrees of efficiency: Planetary reducers present greater efficiency and thanks to its design and internal layout losses are minimized throughout their work. Actually, today, this type of travel mechanisms happen to be those that offer greater efficiency.
Increased torque transmission: With an increase of teeth in contact, the mechanism can transmit and withstand even more torque. In addition, it does it in a more uniform manner.
Maximum versatility: The mechanism is within a cylindrical gearbox, which may be installed in nearly every space.
What regulations apply to planetary gearboxes?
Understand that each producer sets its own procedures when presenting the operating period of the gears or the maximum torque they could bear. Nevertheless, we can find certain regulations governing these parameters.
– ISO 6636 for gears.
– DIN ISO 281: With all the rules that helps to create a correct calculation of the bearings.
– ISO 9409: Component II talks about the look of the output shafts of these geared motors according to diverse specifications.
