Right angle gearboxes (worm and planetary) are durable and built for 90° turns. Inline reducers (parallel shaft and planetary) are an ideal match for motors with high insight speeds, or when gearmotor effectiveness is important. Contact our technical sales staff for help identifying which gearbox alternative is most beneficial for you.
RIGHT ANGLE REDUCERS
WORM GEAR REDUCER
Groschopp’s worm equipment reducers are designed 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 choices providing versatility when incorporating the reducer into item.
RIGHT ANGLE BEVEL GEARBOX

There are three main parts in a planetary gearbox: the sun 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 world gears that revolve around the sun gear. Planetary gearboxes are made of heavy duty metallic such as for example steel and are in a position to handle huge shock loads well. Nevertheless, different planetary gearboxes are designed for specific swiftness, load and torque capacities. The predominant use for planetary gearboxes is usually in automobiles with automated transmissions. Unlike manual transmission, where 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 tranny contains two complete planetary gearsets placed together into one component. Planetary gearboxes are also found in electric screwdrivers, sprinklers and applications that require large or multiple reductions from a concise system. Planetary gearboxes are one of many variations of quickness reducers in fact it is essential that the right mechanism can be used. Gearboxes may even be combined to produce the desired results and the most common kinds are helical gear reducers, worm equipment reducers and inline equipment reducers.
Planetary gearboxes gain their advantages through their design. Sunlight gear’s central position allows the planet gears to rotate in the same path and for the ring gear (the advantage of the planet carrier) to carefully turn the same way as the sun gear. In a few arrangements sunlight gear can simultaneously switch all the planets as they also engage the ring gear. Any of the three components may be the input, the output or kept stationary, which results in lots of different reduction ratio opportunities.
In many planetary gearboxes one element is held stationary with another element 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 elements are engaged. Generally, the load ability and torque boosts with the number of planets in the system because the load is distributed among the gears and there is usually low energy waste; planetary gearboxes are highly efficient, averaging between 96 and 98%. The design is complex, nevertheless, and difficult to access for repairs or maintenance.
Axial or Inline gearboxes refer to this kind of types as Helical, Shaft mounted, or planetary styles.
These gearboxes are very common options for most commercial applications due to 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 known as Parallel shaft gearboxes offer 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 high tech, high torque, high speed applications requiring severe accuracy.
