Right angle gearboxes (worm and planetary) are rugged and built for 90° turns. Inline reducers (parallel shaft and planetary) are a perfect 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 alternative is best for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
Groschopp’s worm gear reducers are designed with a hollow bore and invite for a corner convert with optional dual output. The reducers come in 12 ratios ranging from 5:1 to 100:1, with non-back-drivable ratios 30:1 and higher. Our correct angle gearboxes were created with five mounting choices providing versatility when incorporating the reducer into product.
RIGHT ANGLE BEVEL GEARBOX
bevel-right-angle-gearbox
The right angle bevel gearbox combines the features of our correct angle worm and planetary inline reducers. With a good and efficient correct angle configuration, our correct angle planetary gearboxes provide a robust solution. The right angle bevel gearbox comes in 18 ratios ranging 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 provide the smallest footprint and quietest operation of our acceleration reducers. These gearboxes are made to manage varying loads with small backlash. With framework sizes 52cm, 62cm, and 81cm, 12 ratios ranging from 5:1 to 308:1, we’ve a solution to suit your needs. Our 52 frame size is also available with plastic-type material gears for noise-delicate applications.
INLINE PLANETARY GEARBOX
inline-planetary-gearbox
Our inline planetary gearbox configurations supply the highest performance and best result torque of most our acceleration reducers. These gearboxes are made to handle varying loads with small backlash. Planetary gear 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 suit your needs.
PARALLEL SHAFT GEARBOX
parallel-shaft-gearbox
Parallel shaft gearboxes are the top choice for constant duty applications. Their equipment cluster design provides a highly effective method for dissipating warmth. Parallel shaft gearboxes possess the shortest amount of our inline gear reducer options therefore they work well in environments with limited space. Our parallel shaft gear reducers provide an affordable drop-in alternative solution for most little parallel shaft gearmotors.

There are three main components in a planetary gearbox: sunlight gear, the earth gears and the ring gear. The gears are mounted on the planet carrier which has teeth inside, which may be the ring gear.
Planetary Reducer & Gearmotor
Planetary Gearbox – DieQua Corporation
Planetary gearboxes have the ability to produce many different reduction ratios due to the different planet gears that revolve around sunlight gear. Planetary gearboxes are constructed of heavy duty steel such as for example steel and are in a position to handle huge shock loads well. However, different planetary gearboxes are created for specific rate, load and torque capacities. The predominant use for planetary gearboxes can be in automobiles with automatic transmissions. Unlike manual transmitting, where the operator is responsible 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 transmitting contains two complete planetary gearsets placed together into one component. Planetary gearboxes are also found in electrical screwdrivers, sprinklers and applications that want huge or multiple reductions from a concise mechanism. Planetary gearboxes are among the many variations of quickness reducers in fact it is important that the right mechanism can be used. Gearboxes could even be combined to produce the desired results and the most common kinds are helical gear 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 path and for the band gear (the edge of the planet 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 kept stationary, which results in lots of different reduction ratio options.
In lots of planetary gearboxes one element is held stationary with another component serving as the input and the other as output. The reduction ratios for planetary gearboxes are dependent upon the number of teeth in the gears and what parts are involved. Generally, the strain ability and torque raises with the number of planets in the system because the load is definitely distributed among the gears and there is low energy waste; planetary gearboxes are highly efficient, averaging between 96 and 98%. The design is complex, however, and difficult to access for repairs or maintenance.
Axial or Inline gearboxes make reference to this kind of 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 found in 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 conserving foot print. This is the only inline gearbox version with the option of a hollow output shaft.
Planetary gearboxes are usually chosen for hi-tech, high torque, high speed applications requiring extreme accuracy.
