Linear Motion Assembly Allows Gradual Changes

Linear Motion Assembly Allows Gradual Changes A reciprocating linear motion assembly from Amacoil/Uhing enables the automatic increase or decrease of the travel distance on the fly, without requiring programming or electronic controls. Actuated as the drive moves, a mechanical mechanism on the assembly 'ratchets' the end stops farther apart or closer together in specific increments which are set using a dial. As the end stops move, the stroke length changes accordingly. The assembly is for production/plant managers or machine designers who need to gradually increase or decrease the drive travel distance without investing in complex, costly controls and without stopping the system. Applications include applying adhesives/coatings, spraying, wash downs and winding onto spools with tapered flanges.An affordable, unidirectional motor may be used to drive the system because the stroke length is controlled independently of the drive motor's speed and rotational direction.Uhing linear motion assemblies are available in various sizes and provide axial thrust from 3 to 362kg.Depending on size, linear speed may be up to 4m/sec. Backlash-free Uhing drives feature mechanically controlled and adjusted linear speed and travel direction - without changing gears or reversing the motor.This simplifies design and set up, and helps minimise operating and maintenance costs.
