Correct angle gearboxes (worm and planetary) are tough and built for 90° turns. Inline reducers (parallel shaft and planetary) are an ideal match for motors with high input speeds, or when gearmotor performance is important. Get in touch with our technical sales personnel for help identifying which gearbox solution is best for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
Groschopp’s worm gear reducers were created with a hollow bore and invite for a corner convert with optional dual result. The reducers can be found in 12 ratios ranging from 5:1 to 100:1, with non-back-drivable ratios 30:1 and higher. Our right angle gearboxes were created with five mounting options providing flexibility when incorporating the reducer into product.
RIGHT ANGLE BEVEL GEARBOX
bevel-right-angle-gearbox
The proper angle bevel gearbox combines the top features of our correct angle worm and planetary inline reducers. With a good and efficient right angle configuration, our right angle planetary gearboxes offer a robust solution. The right angle bevel gearbox will come in 18 ratios which range from 5:1 to 1000:1, and it is back-drivable at all ratios.
INLINE REDUCERS
I-SERIES PLANETARY GEARBOX
i-series-planetary-gearbox
Our I-Series little planetary gearbox configurations supply the smallest footprint and quietest operation of our quickness reducers. These gearboxes are made to deal with varying loads with little backlash. With framework sizes 52cm, 62cm, and 81cm, 12 ratios which range from 5:1 to 308:1, we have a solution to fit your needs. Our 52 frame size can be available with plastic gears for noise-delicate applications.
INLINE PLANETARY GEARBOX
inline-planetary-gearbox
Our inline planetary gearbox configurations provide the highest effectiveness and best output torque of most our quickness 
reducers. These gearboxes are created to handle varying loads with small backlash. Planetary gear reducers operate more quietly than parallel shaft reducers. With 18 ratio choices ranging from 5:1 to 1000:1, we have a solution to fit your needs.
PARALLEL SHAFT GEARBOX
parallel-shaft-gearbox
Parallel shaft gearboxes are the best choice for constant duty applications. Their gear cluster design provides an effective method for dissipating warmth. Parallel shaft gearboxes possess the shortest amount of our inline gear reducer options so they work very well in environments with limited space. Our parallel shaft gear reducers offer an affordable drop-in alternative solution for most little parallel shaft gearmotors.
The typical precision PE-series inline planetary gearheads can be found in 40-155mm frame sizes and provide high torque, low backlash, high input speeds and a little package size with a great price/performance ratio.
The PE-series planetary gearbox may be the perfect economy gearbox for all applications where significantly low backlash is not of vital importance.

There are three main elements in a planetary gearbox: sunlight gear, the earth gears and the ring gear. The gears are attached to the planet carrier which has teeth on the inside, which is the ring gear.
Planetary Reducer & Gearmotor
Planetary Gearbox – DieQua Corporation
Planetary gearboxes can easily produce many different reduction ratios due to the different planet gears that revolve around sunlight gear. Planetary gearboxes are made of heavy duty metal such as steel and are in a position to handle huge shock loads well. Nevertheless, different planetary gearboxes are made for specific velocity, load and torque capacities. The predominant use for planetary gearboxes can be in motor vehicles with automated transmissions. Unlike manual transmission, where the operator is accountable for switching gears, automobiles that have automatic transmissions make use of clutches, brake bands and planetary gearboxes to improve the inputs and outputs, therefore adjusting the speeds accordingly.
An automatic transmission contains two complete planetary gearsets positioned together into one component. Planetary gearboxes are also used in electrical screwdrivers, sprinklers and applications that require huge or multiple reductions from a concise mechanism. Planetary gearboxes are one of many variations of rate reducers in fact it is important that the proper mechanism is used. Gearboxes could even be combined to produce the desired results and the most typical kinds are helical equipment reducers, worm equipment reducers and inline gear reducers.
Planetary gearboxes gain their advantages through their design. The sun gear’s central position allows the planet gears to rotate in the same direction and for the band gear (the advantage of the earth carrier) to carefully turn the same way as sunlight gear. In some arrangements the sun gear can simultaneously turn all the planets as they also engage the band gear. Any of the three components could be the input, the output or held stationary, which results in many different reduction ratio options.
In many planetary gearboxes one component is held stationary with another component serving as the input and the other as output. The decrease ratios for planetary gearboxes are dependent upon the number of teeth in the gears and what elements are involved. Generally, the load ability and torque boosts with the amount of planets in the system because the load is certainly distributed among the gears and there is low energy waste materials; planetary gearboxes are extremely efficient, averaging between 96 and 98%. The design is complex, however, and difficult to access for repairs or maintenance.
Axial or Inline gearboxes refer to such types as Helical, Shaft mounted, or planetary designs.
These gearboxes are extremely common choices for most commercial applications because of their robust nature, high permissible radial forces, closely stepped ratios and low backlash.
Helical gearboxes can typically be within applications requiring high permissible radial force, stepped ratios and low backlash.
Shaft-mounted or otherwise referred to as Parallel shaft gearboxes provide an inline option with a versatile and space saving foot print. This is actually the only inline gearbox edition with the choice of a hollow output shaft.
Planetary gearboxes are usually chosen for hi-tech, high torque, high speed applications requiring severe accuracy.
