Right angle gearboxes (worm and planetary) are tough and built for 90° turns. Inline reducers (parallel shaft and planetary) are a perfect match for motors with high input speeds, or when gearmotor efficiency is important. Get in touch with our technical sales personnel for help identifying which gearbox alternative 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 which range from 5:1 to 100:1, with non-back-drivable ratios 30:1 and higher. Our right angle gearboxes are designed with five mounting choices providing flexibility when incorporating the reducer into product.
RIGHT ANGLE BEVEL GEARBOX
bevel-right-angle-gearbox
The right angle bevel gearbox combines the top features of our correct angle worm and planetary inline reducers. With a good and efficient correct 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, in fact it is back-drivable at all ratios.
INLINE REDUCERS
I-SERIES PLANETARY GEARBOX
i-series-planetary-gearbox
Our I-Series small planetary gearbox configurations supply the smallest footprint and quietest procedure of our quickness reducers. These gearboxes are created to manage varying loads with small backlash. With frame sizes 52cm, 62cm, and 81cm, 12 ratios ranging from 5:1 to 308:1, we've a solution to fit your needs. Our 52 frame size is also available with plastic-type material gears for noise-sensitive applications.
INLINE PLANETARY GEARBOX
inline-planetary-gearbox
Our inline planetary gearbox configurations supply the highest efficiency and best result torque of all our acceleration reducers. These gearboxes are created to deal with varying loads with little backlash. Planetary equipment reducers operate more quietly than parallel shaft reducers. With 18 ratio options which range 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 top choice for constant duty applications. Their equipment cluster design provides an effective method for dissipating heat. Parallel shaft gearboxes have the shortest amount of our inline equipment reducer options so they work well in conditions with limited space. Our parallel shaft equipment reducers provide an affordable drop-in alternative solution for most small 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 isn't of vital importance.

There are three main elements in a planetary gearbox: sunlight gear, the earth gears and the ring gear. The gears are mounted on the planet carrier that has teeth inside, which is the ring gear.
Planetary Reducer & Gearmotor
Planetary Gearbox - DieQua Corporation
Planetary gearboxes can produce many different reduction ratios due to the different world gears that revolve around the sun gear. Planetary gearboxes are made of heavy duty steel such as steel and are able to handle huge shock loads well. Nevertheless, different planetary gearboxes are created for specific acceleration, load and torque capacities. The predominant use for planetary gearboxes is usually in automobiles with automatic transmissions. Unlike manual tranny, in which the operator is accountable for switching gears, automobiles which have automatic transmissions use clutches, brake bands and planetary gearboxes to improve the inputs and outputs, therefore adjusting the speeds appropriately.
An automatic transmission contains two complete planetary gearsets placed together into one component. Planetary gearboxes are also used in electric screwdrivers, sprinklers and applications that require large or multiple reductions from a concise system. Planetary gearboxes are among the many variations of rate reducers and it is essential that the right mechanism can be used. Gearboxes may even be combined to create the desired results and the most common kinds are helical equipment reducers, worm equipment reducers and inline equipment 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 ring gear (the advantage of the earth carrier) to carefully turn the same way as the sun gear. In a few arrangements the sun gear can simultaneously turn all the planets as they also engage the ring gear. Any of the three components may be the insight, the output or held stationary, which results in many different reduction ratio possibilities.
In many planetary gearboxes one component is held stationary with another component serving as the input and the other as output. The reduction ratios for planetary gearboxes are influenced by the number of teeth in the gears and what components are involved. Generally, the strain ability and torque increases with the amount of planets in the machine because the load is distributed among the gears and there can be low energy waste; planetary gearboxes are extremely efficient, averaging between 96 and 98%. The look 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 very common selections for most industrial 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 offer an inline option with a versatile and space conserving foot print. This is the only inline gearbox edition with the choice of a hollow result shaft.
Planetary gearboxes are usually chosen for hi-tech, high torque, high speed applications requiring intense accuracy.
