The FRIEDRICH Unbalance Exciter serves to drive vibratory conveyors, screens and other vibration systems with very high load and/or very high flow rates. Unbalance Exciters generate a linear oscillating motion. The forced synchronization of the weights are not transverse vibrations generated when switching on and off the machine.General specifications
1 The unbalance exciters can be operated from a speed of 500 min-1 up to the maximum permissible speed. 2 Working moment = 2 x static moment. 3 UE 50-6 F, UE 58-6 F, UE 67-8 F, UE 80-8 F and UE 65-6 F will be changed to the new type F16 by the end of 2016. Technical data please refer to previous catalogue (11.12).
Allowable Operating ambient temperature:
An ambient temperature of -40°C to +50°C and an operating temperature of 80°C must not be exceeded. Depending on the ambient temperature, a transmission oil is used with the required viscosity. Please consult FRIEDRICH for other operating temperatures.
Drive Motor Selection:
The drive motor can be all standard AC motors with 50Hz. The tightening torque must be in the range of 0-300rpm 2.5-fold amount of nominal value. When pairing two or more Unbalance Exciters on link propeller shafts, the drive motor chosen must be correspondingly larger.
The first two letters are an abbreviation for Unbalance Exciter. The following figures give a hundredth of the maximum working torque in kgcm (Working Moment = 2 x static moment). This is followed by a hyphen and the maximum permissible speed of the drive motor which is indicated by the pole number.
