What are the standard Cyclo® input speeds?
In general terms, the speeds are 1750 and 1165 RPM. The selection tables in our catalog are based on 1750, 1165, 870, 580, and 50 RPM. When non-standard input speeds are used, the kilowatt (or horsepower) and torque ratings also vary.
The service factor of the Cyclo® reducer is generally higher than the traditional gearmotor. Why?
This is because Cyclo has a high teeth engagement rate. Since the Cyclo gearing has two-thirds of its reduction components in contact at all time, it can withstand higher shock loads and is more stable than traditional involute gearing.
What is the principle of Cyclo® technology?
Cyclo® is a type of internal planetary gear. The planetary gear has cycloidal-shaped teeth. All torque-transmitting parts roll, not grind. Unlike the normal involute teeth with limited contact points, a Cyclo has two-thirds of its reduction components in contact at all times. Multiple teeth share the load, so therefore the Cyclo® is not susceptible to tooth breakage.
Can the Cyclo® Drive be mounted vertically?
Models having an "N" after the nomenclature symbol "C (Cyclo)," are universal mounting models that can be mounted in any direction . However, when there is an "H (horizontal)," "V (vertical with slow speed shaft downward)" or "W (vertical type with slow speed shaft upward)," after the "C," the unit cannot be mounted in any direction other than the one specified.
Are mounting bolts included with the Cyclo®?
Mounting bolts are not included. Refer to the maintenance manual for mounting bolt specifications.
What should I do for the maintenance of small models?
Cyclo frame size 606 to 612# are called “MF: Maintenance Free.” Grease replenishment is not required for normal operating conditions, and grease fittings are not utilized. Sumitomo recommends overhaul and grease change at 20,000 hours or 4-5 years. However, when the Cyclo uses special grease for high or low ambient temperature and grease fittings are installed, then grease replenishment and grease changes are required according to the appropriate factory schedule.
What is the allowable input speed of the Cyclo®?
Generally, Cyclo® Drives allow for input at 3600r/min for up to 3HP, 6:1 to 87:1 ratio. For more than 3HP, it varies depending on frame size and reduction ratio. Many Cyclo models can accept input speeds of up to 3,600 RPM. However, the maximum allowable input speed is dependent upon the model number and the reduction ratio.
In the Cyclo® catalog, there are more than two reducer types indicated for one motor input capacity. Which reducer model should I choose?
Selection should be made based on required Service factor. The Service Factor value depends on the load characteristics and operation time for the customer’s application.
What is the largest reduction ratio actually available with a Cyclo®?
Theoretically any combination is available by multiplying single reduction ratios: 6, 8, 11, 13, 15, 17, 21, 25, 29, 35, 43, 51, 59, 71, 87, and 119:1.
What type of lubrication method does the P4 use?
Hansen P4 units use one of the following systems:
- Splash Lubrication (standard with horizontal shaft gear units for speeds between 750 and 1800RPM at the high speed shaft. Gears and output shaft bearings are lubricated by immersion in the oil bath. Oil splash from gears fill the oil pockets in the housing, assuring gravity circulation lubrication of the bearings via channels in the housing and covers.)
- Force Feed Lubrication (all rotating elements above oil bath level are lubricated by a gear pump forcing the oil through pressure lines. Forced feed lubrication is available as circulation lubrication or pressure lubrication.
