Colombo Filippetti - Index Drives - CF3 Medium Series
The CF3 Index Drive series includes models 65P, 80P, 105P, and 130P, each with varying dynamic output torque and static torque capacities. These drives are designed for precise, repeatable index motion with features like self-locking in dwell, zero backlash, bidirectional motion, and smooth operation. They are compatible with oil-bath lubrication and have worm gear reducers directly splined to the housing.
The CF3 index drives are available in configurations such as standard units (VS), units with optional input (VL), standard with reducer (VR), and standard with motor and reducer (VRM). Configurations with brake motors (VRA) are also offered.
Components include parallel shafts, separate cam/follower units, and high-strength alloy steel cams with hardened profiles. The cam hub has a hollow shaft and keyway, while the dial plate features a central clearance hole and flange mount. The design supports high load capacity with yoke-mounted cam followers.
Constructed with prism-shaped sealed cast iron housing, these units have machined outer surfaces and support on six sides, allowing mounting in all positions. They feature parallel shafts projecting in input and output, with roller bearings on opposite taper roller shafts.
The drives can be mounted in various positions, with specific configurations for input and output shaft orientations. The housing includes standard mounting holes, and shafts can be bored to a maximum depth of 20 mm.
Each drive is identified by a code indicating its configuration, number of stops, and index period, aiding in selecting the appropriate drive for applications.
The document outlines various reducer mounting possibilities, ensuring flexibility in installation and integration into different systems.
The units conform to System International/Severity Index SI standards, with tolerances according to UNI – ISO 2768-1 and UNI EN 22768-1. Illustrations follow UNI 3970 (ISO 128-82) standards.
Reversing the input shaft's direction also reverses the output shaft's direction without altering kinematic features. Correct assembly conditions, such as parallel shafts and suitable lubrication, are emphasized for optimal operation.
The CF3 INDEX DRIVE requires firm attachment of input and output shafts to the machine, avoiding flexible transmission parts or those introducing backlash. Overload protection clutches should be fitted to the output shaft for safeguarding.
The drive can be mounted in any position due to its housing shape and machined surfaces. For low or medium speeds (≤150 indexes/min.), it is pre-filled with lubricant and requires no maintenance. For higher speeds (>150 indexes/min.), oil changes are necessary, and the housing is delivered without lubricant, requiring filling with AGIP BLASIA 150 OIL. The identification number includes mounting position details.
The identification number is structured according to a chart, specifying the mounting position of the worm gear reducer in versions VRS, VSP, and VSM.
Versions VSR, VSP, and VSM are equipped with worm gear speed reducers directly splined to the input shaft, offering a compact motor-driven unit. Reduction ratios allow speeds between 14 and 200 indexes/min. The VSL long-shaft version is designed for the worm gear reducer, which can be mounted in any of the 8 standard positions. Orders must specify reducer mounting position, motor unit details, and other specifications like reduction ratio, motor dimensions, and electrical details. Alternative motor assemblies, such as speed variators or brake/clutch units, can also be fitted. For further information, contact the supplier to discuss specific requirements.

DRIVE COMPONENTS - Parallel shaft. - Separate and pre-coupled cam/follower units. - Cam hub with hollow shaft and keyway. - High-strenght alloy steel cam with hardened, ground profiles. - Dial plate with central clearance hole and flange mount on each side. - High load capacity with special yoke-mounted cam followers. > Fig. 1a The 1/2/3/4 - stops CF3 INDEX DRIVES with complete (360) input shaft rotation produce 1 cycle (transfer + dwell) of the output shaft. This means that 50 rpm of the input shaft produce 50 indexes/min in output. Correct operation of the INDEX DRIVE is guaranteed by the following...

IDENTIFICATION NUMBER The identification number of the INDEX DRIVE is made up in accordance with the chart. The mounting position of the worm gear reducer in versions VRS, VSP and VSM is specified in the paragraph "REDUCER MOUNTING POSSIBILITIES". operating at medium and high speeds (>150 indexes/min.), the oil should be changed at intervals. The housings are supplied complete with oil inlet/inspection window/outlet plugs and are delivered without lubricant; it is therefore up to the client to fill the housing with the correct amount of oil prior to start-up. The recommended lubricant is AGIP...

REDUCER MOUNTING POSSIBILITIES D1 D2 The CF3 INDEX DRIVES in versions VSR VSP and VSM are fitted with worm gear speed reducers suitably selected and splined directly to the input shaft. This system presents a combination of rigid power transmission and a very compact motor driven INDEX DRIVE unit. The range of reduction ratios avaitable produces speeds between 14 and 200 indexes/min., thereby meeting the majority of application requirements. The CF3 INDEX DRIVE designed for the worm gear reducer to be splined on, is the VSL long-shaft version. The reducer can be mounted on the CF3 INDEX DRIVE...
