Linear Drive Slowdown is Independent of Motor -- Simplifies Operation, Enhances Accuracy

Uhing Company now offers an option for its Model RG rolling ring linear drives whereby the end stop assemblies are fitted with specially machined v-shaped cams to decrease the linear speed of the drive prior to reversal without using electronic controls or reducing motor speed. After reversal, the cams permit smooth ramp up of the drive speed eliminating possible whipping action of tools such as spray heads or cutting blades.

Dissipating momentum in this manner enhances processes where over-travel or abrupt movement of the tool head is undesirable and smooth reversal improves accuracy. Slowdown cam applications include applying coatings, slitting, spray painting and moving measuring probes. Because ramp down/up of linear speed is mechanically controlled, independent of the motor, operation of the drive is simple requiring only minimal operator training.

The slowdown cam option is available on new Uhing rolling ring drive assemblies and, in some cases, may be retrofitted in the field. The length of the cam arms is specific to the size of the Uhing drive on which the cam will be used. Once installed, the slowdown cams must be adjusted in relation to the position of the end stops to assure proper functioning and accurate location of the drive reversal points. Amacoil technical representatives can assist with this process and also in sizing and selecting Uhing drives for custom applications.
