planetary gearbox is normally a type of top quality and low backlash right angle gearbox, which makes the gearbox easily mounted to the motion system and offer a solution to solve the space problem. The inner engineering was created with spiral bevel gears which top features of better meshing performance, clean transmission, low noise and high rigidity.
right angle gearbox isn’t only the perfect option for the movement control system with limited space, but likewise the best choice for the transmission event that must change the motion path. So it can help users to save the running expense and improve the transmission efficiency.

Right-angle gearheads happen to be flange-mounted gearheads that use worm gears and unique helical gears. They let motors to be mounted at best angles to the axis of tools such as belt conveyors. They are available in hollow shaft RH and sound shaft RAA types and are perfect for keeping equipment compact.
A right angle gearhead is often used when it’s essential to fit a servo motor into a tight space. The productivity shaft of the proper angle gearhead reaches a 90-degree angle to the motor shaft. Therefore, the majority of the gearhead housing, and all the motor housing, is parallel to the side of the device, providing a smaller equipment envelope. Remember that some gearheads, such as worm gearheads, have an inherent correct angle design because the travel axis of the worm (screw) is at a 90 degree position to the axis of the worm gear.

Separate motors and gearheads
Most motion control systems that employ gearing use separate motors and gearheads. This approach lets you opt for the electric motor and gearhead best suited for the software, even when they come from different manufacturers. Commonly, you can mount gearheads to just about any servo motor. All that is required is normally to mount the mating flanges jointly using standard screws. This construction is more flexible than an integrated gearmotor and it’s easier to maintain. Gearheads wear out more quickly than the motor itself, so when a gearhead fails, you merely have to replace it and not the motor.
That said, a built-in gearmotor is the most suitable choice for certain applications. One benefit of this approach may be the overall length of the assembly is definitely an inch or more shorter than an assembly with another gearhead and motor.
System design is very simple too because you only need a single velocity and torque curve to determine if a gearmotor will provide the necessary performance to electric power your motion control program. This helps eliminate design errors.
And assembly is very simple as well. As the gearhead and electric motor are integrated, it’s unattainable make the assembly flaws discovered when mounting a gearhead to a motor.
Use in food processing
Integrated gearmotors work very well in tough environments such as for example found in the food digesting industry. Because gearmotor housings will be as well made with 300 grade stainless and must satisfy IP 69K standards for level of resistance to the ingress of excessive temperature-high pressure water, plant personnel can simply clean down machinery without needing to be anxious about harming it. The design also eliminates the seam between the electric motor and the gearhead, so there is no place for meals to get caught.
A newer trend is the utilization of flange-face gearheads. Instead of an outcome shaft, flange-face gearheads possess a rotating disk with screw holes on the outcome. The machine being driven mounts directly to the flange. This set up eliminates the need for a flexible couple and most of its associated concerns. Both gearheads and gearmotors are available with a flange encounter.
Fig 2. To mount a gearhead to a servo motor, all that’s needed is is to add the mating flanges alongside one another using standard screws. Below, a split collar system on the input gear secures it to the engine shaft.
There are many different types of gearheads for use in a motion control system. Knowing the attributes of every will help you make the best choice for different applications:
Deciding on the best gearhead
There are numerous types of gearheads for use in a motion control system. Learning the attributes of each will help you make the best option for different applications:
Spur gears have pearly whites that function perpendicular to the facial skin of the gear. They are small, cost-effective, and with the capacity of high equipment ratios. Negatives include they will be noisy and prone to wear.
Worm equipment drives are being used where it’s essential to transmit power in a 90-degree angle and where high reductions are actually needed. Worm drives will be specific, run quietly, and want little maintenance. Cons include they are comparatively low in effectiveness and are nonreversible.
Planetary gear drives are so called as the gear arrangement somewhat resembles the solar system. A central gear, called the sun equipment, drives planetary gears positioned around it. The planetary gears rotate the outcome shaft of the gearhead. Advantages include small size, high productivity, low backlash, and a high torque to excess weight ratio. Disadvantages consist of complex design and huge bearing loads.
Harmonic gear drives include a wave generator, flexispine, and circular spine. Positive aspects include low weight, compact design, no backlash, excessive gear ratios, great torque capacity, and coaxial source and output. A drawback is the gears are inclined to wear.
Cycloidal drives have an input shaft that drives an eccectric bearing which then drives a cycloidal disk. Cycloidal speed reducers are capable of great ratios while remaining tiny in size. Drawbacks include increased vibration, due to the cycloidal motion, which can cause don on the cycloidal disk’s teeth.
Fig 3. You only need a single acceleration and torque curve to determine if an integrated gear motor like this gets the necessary performance to ability the motion-control system.
