The Cyclo speed reducer, by virtue of its smooth, almost frictionless operation (unlike traditional helical gears), has a thermal rating that far exceeds its mechanical capacity, and all but eliminates the conventional limitations due to heat.
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.
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.
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.
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.
Mounting bolts are not included. Refer to the maintenance manual for mounting bolt specifications.
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.
To select the proper reducer for your application, you need to know: Application: type of driven machine
Hours of operation per day
Motor horsepower (HP) and speed (RPM)
Ambient environment (altitude, dusty, chemical, explosive, water)
Ambient temperature and humidity
You must also note any special environment factors or operational requirements. This information will be important in determining your application's service factor.
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.
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.
With an increased torque capacity, the new Steel Taper-Grip® bushing can be used in reversing and/or high start-up applications. The new Steel Taper-Grip®bushing can be used on all Taper-Grip® products.
The Taper-Grip® bushing is integral to the Cyclo® BBB4 and provides for easy mounting and removal to and from the shaft of the driven machine. Because it requires no key way, the shaft isn’t weakened and maximum torque is transmitted.
The Cyclo® speed reducer, by virtue of its smooth, almost frictionless operation (unlike traditional helical gears), has a thermal rating that far exceeds its mechanical capacity and all but eliminates the conventional limitations due to heat.
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.
Backstops are safety devices and have to be inspected at regular time intervals. The periodical inspection is to be carried out by authorized personnel. The frequency of the inspection depends on the type of application. Please refer to the P4 service manual for recommended inspection intervals
In general, reducers and gearmotors are rated for specific conditions and operating requirements of the application by the use of AGMA-defined Service Factors. There are three AGMA load classifications for reducers: uniform (U), moderate shock (M) and heavy shock (H), and three AGMA load classifications for gearmotors: I, II, and III. Refer to our catalog for a list of AGMA load classifications. These Service Factors are used in the product selection process to adjust for the specific conditions and operating requirements of your application.
Please consult a Sumitomo Sales Representative. They will review your application and provide an optimum Paramax selection.
