Why? The world of servo-driven tables is the connection between electronic and mechanical disciplines. The SRP table allows the machine designer to manage the know-how of the system and maintain full control over it. At the same time, it allows full flexibility of use, thus allowing the Electronic Operator to perfect the tuning of the machine and enhance its combination of mechanical and electronic features. The high versatility and flexibility of this table helps the increasingly pressing market demands for the reduction of development times and time-to-market. The SRP field of use crosses...

The value of displacement accuracy Generally, the good operation of a mechanical system is a function of controlling key factors such as backlash and elasticity of the system, whilst respecting the assigned movement. The SRP rotary table, with orthogonal axes, was designed and manufactured to allow achieving these goals. The SRP is a constant velocity rotary table, with no backlash and with high mechanical rigidity. These features can easily be appreciated in terms of system controllability and positioning accuracy, as shown in the charts. Mechatronics application with SRP Advantages: •...

Enhancement of motor performance OUT One of the tasks for a machine designer is to create an energy efficient and effective system using the resources available, thus minimizing the average power demand of the system. This operation, for example, involves the homogenization of the electricity demand for the control of the motor and, therefore, of the application. Considering this, the SRP effectively reduces the inertia of the application with the square of its internal ratio, thus allowing the motor to enhance its mechanical features and control the system more efficiently. Input torque...

Versatility of application The compact and symmetrical design, the possibility to vary at will the law of motion and the large central through-hole make this table suitable for any situation and field of application. This flexibility allows the configuration of a unique machine, permitting any subsequent project change or variation required by the end-user. The high accuracy, the absence of backlash throughout the movement and the high rigidity allow it to work in applications requiring very close tolerances and high production rates. The perfect collaboration with the drive allows it to...

Benefits of use - example SRP coaxial outlet • Possibility of axially linking two or more independent motions • Through hole to allow for shafts or accessory cables • High positioning accuracy for each output axis Coaxial outputs • Use of angular transmissions • Introduction of backlash makes it unsuitable for axis tracking operations • Impossible to specify a throughhole coaxial with the ou

SERVO-ROLLER POSITIONERS are rotating roller positioners with a constant-velocity globoidal cam and no backlash. The globoidal cam moves in output disc on which the needle rollers are installed and are preloaded together in order to guarantee the total absence of backlash in any position of the cam. The tables are available in 3 sizes: SRP63, SRP100 and SRP150.

Maximum flexibility of the output motion High accuracy Compact housing with all surfaces machined High rigidity output disc with flange connection Prepared for servo-motors with user programmable movement Large central through-hole

Servo-roller Positioner The preloading system, the absence of backlash and the needle rollers guarantee a regular movement along the entire operating cycle, a high rigidity and repeatability of positioning, high yields accompanied by a long life and very low maintenance. The servo-motor fitted on the cam input shaft and secured directly on the side of the box allows free programming of the table, with total control of its movement and speed and the acceleration of the output disc, as well as all the dynamic and kinematic parameters enabled by the drive selected.

Servo-roller Positioner Setting Needle rollers Mechanism with orthogonal axes preloaded with no backlash. The cam profile has been optimised to ensure uniform and constant contact of the wheels in any position of the cam The use of needle rollers combined with an optimized profile section cam allows low moving friction torques and reduced first detachment torques. Direct connection to the motor The large through-hole in the output disc allows easy passage of control and power systems, as well as shafts and other equipment, providing maximum design freedom. The motor can be easily connected...
