Rotary actuator E1

- we took great care, by the development, to have small dimensions - if front-fl ange- or foot mounting, with or without threads, we can fi t the E1 on all kind of practicable technical mounting possibilities > - less load on the ball bearing, freeing it for more important tasks- extending the service life of the rotary actuator > - if you manufacture the hub, it is not necessary to regard the exact position of the keyways.- the total angle can be re-adjusted at any time > - in spite of the possibility is the radial- and axial power through the application of ball bearings by low hydraulic...

- short delivery times through fl exible storage - individual solutions for your product - quality assurance according to DIN EN ISO 9001 - negating the need for expensive proportional or servo controls with virtually identical characteristics > - through precise combined helical gears and low friction seals, is the E1 already from 10 bar economically applicable - assuring positive power/torque transmission even at peak load conditions > - the axial force required for mounting the shaft on the hub can be exerted at the end of the shaft, preventing destruction of the ball bearing- the...

The rotary actuator E1 is used for rotating or turning useful loads.As in a hydraulic cylinder the piston K (fi g.-2) is moved in a linear motion between the two mechanical end positions E1 and E2 by means of hydraulic power.Through the multiple helical gears the linear motion is mecha-nically transformed into a turning motion and transferred to the drive shaft W.The opposed direction of the helical gears G1 and G2 causes a simple stroke of the piston to produce a doubling of the angular movement.The pairs of helical gears are not self-inhibiting. Positive lubrica-tion and nitriding of the...

From view F, the drive shaft W will rotate anti-clockwise (arrow A) when pressure is applied to port A1. A different direction of rotation is available as a special feature. The hydraulic fl uid used in the rotary actuator does not exceed the pollu tion classifi cation 19/15 in accordance with ISO 4406. Therefore, a fi lter setting of < 25 > m should be installed in the pressure line. With hermetically sealed containers a return fi lter should suffi ce. With open containers a pressure fi lter must be installed in the compressed air line. The maintenance inter- vals described above should be...

The end angle can be re-adjusted at any time by 5 .In conjunction with the adjustable drive shaft datum, it is there- fore possible to adjust the initial and fi nal position of the total angle required. For adjustment, you only have to loose the counter nut KM. After this, you can reach the wished rotating angle through screwing in or out of the adjusting insert RE. A positioning is only possible, in the state of no pressure. The angle of rotation can be adjusted individually with this option, both over its total range of rotation and over a partial range (e.g. total angle 270 , desired...

The locating pin SZ (fi g. 6) is intended for the fi tting of cams Z5 or other control equipment. It simply screws or is glued into the tapping provided at the back end of the shaft. It can be supplied at a later stage without reconstruction of the rotary actuator. The locating pin should not be used for torque transmission or for limiting the angle of rotation. This option allows the respective end positions to be touchless and electronically confi rmed and the intermediate angles to be recalled. The locating pin SZ and the cam Z5 are included in this option. Also the mounting of a couple...

Because of its torque, angle of rotation, pressure range, po-sitioning accuracy, stability of position, type of attachment and dimensions, the Eckart E1 rotary actuator can be used in a wide range of applications.The selection and the size depends above all on the de-mands and the operating conditions under which the rotary actuator is operating. For the planning of special items, it is also important for us to be aware of all technical details.In order to provide this we have prepared a catalogue of questions on page 15 which you can fax us if any lack of clarity emerge. Our staff will be...
