Nexen launches IP65 precision rotary indexer
Nexen Group is introducing the Motor Ready Sealed precision rotary indexer. The MRS indexer retains the benefits of the company's existing patented precision roller pinion drive design - ie zero backlash, high precision, high torque and high acceleration - while delivering significant new benefits. It is suitable for precision rotary indexing applications such as machine tools, semiconductor fabrication, robotics, automated welding, medical packaging, assembly and cutting systems.
A high roller pinion-to-gear ratio enables users to direct-drive the system with the addition of a servo motor, thereby eliminating the cost of a reducer. This also reduces engineering and installation time. For high-load applications, customers can drive the system with a reducer/motor combination. In addition, the gear-to-pinion reaction loads are fully supported, so the servo motor shaft is not subjected to radial loading, which eliminates the need for costly high-output capacity reducers in high-load applications. All of these features reduce engineering and installation time.
The MRS precision rotary indexer offers high indexing precision, with one-way positional accuracy up to +/-31arcsec and one-way repeatability up to +/-5.2arcsec. Unlike other drive systems, there is zero backlash from the motor through the driven load. Acceleration is claimed to be up to twice as fast as other technologies. The MRS can handle high speeds up to 304rpm. For faster installation, it is motor/gearbox ready. Available in sizes of 150, 250 and 350mm output bolt circle diameter, it has a large open centre to optimise performance in small spaces. The MRS is fully sealed and IP65 rated. It requires minimal maintenance and has a long service life.
