Torkdrive cycloidal speed reducer for high torque

Torkdrive cycloidal speed reducer are extremely quiet and reliable. They provide optimum torque capacity in a compact design. With multiple ratios available, they are a good choice for high torque, low noise applications.
Bucket Elevator Gear can be combined to create high reduction gearheads. Standard ratios can reach 2500:1. These high ratio units use small motors, and the NEMA Adapters conveniently furnish the appropriate configuration.

a new development of the helical bevel gear

helical bevel gear are component sets without integrated angular ball bearings, which makes them especially compact. The gear sets can be combined with different external output bearings.

The Helical Bevel Gearbox is a completely new development! Due to their high output speed, these component sets are ideal for highly dynamic pick & place, handling and positioning applications.

Bucket Elevator Gear for maximum precision

Bucket Elevator Gear are designed for high output speeds and are therefore ideal for the automation of robot axes, machine tools and conveyor systems.

helical bevel gears component sets stand for maximum precision, extremely low vibrations and low inertia. Our ingenious two-stage cycloidal design makes the gears insensitive to shock loads and allows high torques. The force transmission via rollers guaranteed high efficiency ratio of up to 85 percent and a long service life. The component sets series also feature integrated angular ball bearings. Hence, there is no need for the customer to provide bearings, as well as the manufacturing costs for the bearing mounts.

the reliable and precise of the helical worm gear motor

These helical worm gear motor feature a large hollow shaft for the feed-through of cables and supply lines. The hollow shaft rotates at the output speed.
We designed the Helical Bevel Gearbox especially for the reliable and precise positioning of heavy loads of up to 9 tons. The cast iron base ensures stable and durable floor mounting. Their high performance and precision make them superior to conventional worm gears and camshaft gears.

High shock resistance of the ball mill gearbox

The ball mill gearbox cam has exactly one eccentric section less than the pin ring has pins. A 360° revolution of the crankshafts therefore causes the cams to rotate one pin farther, whereby practically all the gear teeth are in continuous contact with the pins. The rotating movement is then transmitted from the input shaft to the crankshafts via the spur gear stage, and these then shift the cams in the pin ring and, consequently, generate a reduced speed with high precision. This technology enables the small worm gearbox gears to absorb 5 times the rated torque in emergency-stop situations without suffering any damage. The resulting overall reduction is the same as the product of the two reduction ratios (spur gear stage and eccentric stage).

Cycloidal gear reducers a “normal class” of quality

Cycloidal gear reducers are supplied with mounting flanges must be assembled with motors whose shaft and flange tolerances correspond to a “normal class” of quality in order to avoid vibration and forcing of the input bearing. Motors supplied guarantee that this requirement is fulfilled. For ease of consultation, the correspondence of the size of the B5 and B14 motor with the sizes of the shaft and the motor connection flange are shown in the following table.

hollow shaft gearmotor, as the motor connection flanges are separate from the body it is also possible to have a shaft / flange combination that does not correspond to the table, e.g. 19/140, thereby offering adaptability for other non-unified models such as the brushless or direct current types.
