The Circulute
3000, readily available with inputs for both servo and induction
motors, features a compact design with single reduction ratios of
11:1 to 71:1 at 95% operating efficiency.
It utilizes
52100 grade bearing steel on all of its speed reduction components.
It is also offered with a full two year warranty. This warranty, not
limited by hours of operation, is offered because this Shimpo unit
is able to endure abuse that would break the teeth of ordinary speed
reducers
Offered in two backlash ratings
and multiple mounting options, the Circulute 3000 has a unique two
piece pin housing design that guarantees output shaft backlash
ratings of less than 6 arc-min.
Applications suited for the
Circulute 3000 Reducer include: machine tools; rotary valves;
feeders; rotary tables; steel industry roll drives; mixers;
grinders; dryers and conveyors.
The reducer is also offered with
top mount, shovel base input, IEC motor inputs, designs for overhead
conveyor applications and a wide range of options for unique
applications.
As a further innovation, Circulute
3000 is also available with an integral pulley. This is in addition
to their standard assembly configurations. It is also offered with a
hollow output shaft. These configurations, available in three sizes,
can be used in a number of situations to create a compact footless
drive package. It is available in the following configurations:
Circulute pulley with hollow shaft; shaft input with hollow shaft
output; C-face input with hollow shaft or Circulute pulley, flange
mount.
The Circulute 3000
Speed Reducer delivers the features today’s industry needs:
- High reduction ratios, without
sacrificing efficiency.
- Compact designs, without
requiring special motors. Exceptional shock load capacity,
without having to oversize.
- Greater overhung load
capacities, without using expensive special components.
- A precision backlash
option, without resorting to special gearing.
All of this, while requiring
minimal maintenance, is available with mounting and output shaft
dimensions equivalent to those of the SM Cyclo® product. Your
Shimpo reducer can be dropped in to replace the other brand with no
modifications to your mounting plate!
How it works:
- When the input shaft makes one
rotation, the eccentric roller bearing also rotates once in the
same direction.
- The wheel is driven by the
eccentric roller bearing. It revolves around the internal pins
with its teeth engaging with consecutive pins.
- When the eccentric roller
bearing has completed one full rotation, a tooth initially in
mesh with a pin will be positioned as many teeth behind its
initial position as the difference between the number of
internal pins and the number of teeth. As a result, the wheel
rotates slowly in the opposite direction of the input shaft.
- The rotational motion of the
wheel is transmitted to the output shaft through the carrier
pins. The power train sets apart from other speed reducers. Its
main power transmission components include: an eccentric roller
bearing drives a wheel around a set of internal pins, keeping
rotational inertia low. The result: exceptional efficiency, long
service-life and reduced wear.

BENEFITS
|
High Efficiency
Cycloidal Reducer Design
|
- Single stage
reduction ratios up to 71:1 saves space
- Rolling motion
minimizes friction and wear, reducing heat,
resulting in a 95% efficiency rating per stage
- 500% shock load
capability as there are only compressive forces
rather than shear forces on the tooth
- Low speed of
cycloidal wheel results in minimal reflected inertia
less wear, and extremely long service life
- Due to the large
overall “tooth / pin” contact area, select a
Reducer using smaller mechanical service factors
|
Two Backlash Ratings
|
- Standard backlash
offers the highest available torque rating at an
economical price
- Precision backlash
results in tighter positional tolerances
|
Multiple Inputs: NEMA
C-Face, Servo Square Flange, Shaft Input, Shovel Base,
Top Mount
|
- Versatility to fit
whatever prime mover is needed for the application
- NEMA and servo
input flanges are compact “quill-style”
hollowbore configuration, eliminating input
couplings and guards
- Quill-style input
features an input support bearing to control
fretting corrosion between motor shaft and reducer
hub, and permit tighter internal tolerances
- NEMA input flange
includes threaded back-off holes for easy motor
removal
|
Straddle Mount Output
Shaft Bearings (sizes D, E, F)
|
- Supports output
shaft and drive pins to provide exceptional overhung
and thrust load capability, without the need for
special bearings or housings
|
Multiple Mounting
Options: Base, Flange, Ring
|
- Versatility to fit
anywhere on your machine
- Ring style allows
output bearing to extend well within the machine for
greatest overhung load rating
