Product catalog summary
Introduction
The CF3 Oscillating Drives are mechanisms that transform constant rotary motion into intermittent oscillating motion using a conjugate cam transmission and roller feeler. They are recognized for their precision, high speed, low vibration, and versatility, making them ideal for modern automatic machines.
Description
The output shaft's oscillation is referred to as "Angular Stroke" (H). A complete cycle consists of two revolutions in opposite directions, divided into four periods: Motion Period "A", Dwell Period "B", Motion Period "C", and Dwell Period "D". The cycle begins with Motion Period "A".
Specifications
The document details specifications for the CF3 Oscillating Drives series (65P, 80P, 105P, 130P), including dynamic output torque, RPM, angular stroke, static torque, acceleration factor, and input torque factor. These specifications are presented in tables, showing variations across different cycle periods and angular strokes.
Assembly
The CF3 Oscillating Drives can be assembled in four configurations based on the rotation direction of the input and output shafts: DD, DS, SD, and SS, with DS as the default unless specified otherwise.
Versions
The CF3 Oscillating Drives are available in various versions, though specific details are not provided in the excerpt.
Overview of CF3 Oscillating Drive Series
The series includes models 65P, 80P, 105P, and 130P, each tailored for specific mechanical automation applications. They feature a compact double spherical cam mechanism for synchronized intermittent movements.
Drive Components
Components include parallel shafts, separate cam/follower units, and high-strength alloy steel cams. The cam hub has a hollow shaft with a keyway, and the follower hub is designed for high load capacity with special yoke-mounted cam followers.
Housed Units
Made of prism-shaped cast iron with machined surfaces, allowing flexible mounting in all positions. They include roller bearings and oil-bath lubrication, with a worm gear reducer directly splined to the housing.
Mounting Positions
The drive can be mounted in various positions, with lubrication for life at low and medium speeds (≤150 RPM). For higher speeds, oil changes are necessary, and the housing includes oil inlet/inspection/outlet plugs.
Reducer Mounting Possibilities
Versions VR, VRP, VRM, and VRA come with worm gear speed reducers, offering various reduction ratios. The reducer can be mounted in any of the 8 standard positions, with different motor assemblies available.
Specifications and Notes
Each model has specific dimensions and specifications, including keyway positions and mounting hole details. Proper operation requires parallel shafts, pre-loading of followers, and suitable lubrication.
Conclusion
The CF3 Oscillating Drive series provides a versatile and precise solution for mechanical automation, with various configurations and mounting options to meet diverse industrial needs.

CF3 OSCILLATING DRIVE INTRODUCTION The CF3 OSCILLATING DRIVES are parallel axis mechanisms, which transform the constant rotary motion of the input shaft into intermittent oscillating motion of the output shaft by way of a conjugate cam transmission and roller feeler. The features, which make the CF3 OSCILLATING DRIVES a high DESCRIPTION The width of oscillation of the output shaft is known as "ANGULAR STROKE" and is indicated by the letter "H". The full cycle, comprising two revolutions of the same width in opposite directions (oscillation) with or without intermediate dwell periods, is produced...

ASSEMBLY The CF3 OSCILLATING DRIVES can be assembled on four different ways, regardless of the mounting position. The type of assembly depends on the direction of rotation of the motion input and output shafts. If the CF3 OSCILLATING DRIVE is viewed from the output shaft side, "Side B", it can be seen that: 1. The input shaft can rotate clockwise, in wich case it is marked "D", or anti-clockwise, in which case it is marked "S". 2. If motion period "A" only is considered, the output shaft can rotate clockwise, and is marked "D" , or anti-clockwise, and is marked "S". Motion period "C" always rotates...

CF3 OSCILLATING DRIVE DRIVE COMPONENTS - Parallel shaft - Separate and pre-coupled cam/follower units - Cam hub with hollow shaft and keyway - High-strength alloy steel cams with hardened , ground contours - Follower hub with central through hole and flange mount on both sides. - High load capacity with special yoke-mounted cam followers. Notes • Reversal of the direction of rotation of the input shaft also reverses the chronological sequence of the cycle periods. This is equivalent to crossing the Timing diagram from right to left. • Keyway "T" of the cam hub is positioned halfway along indexing period...
