- through precise combined helical gears and low frictionseals, is the SM4 already from 20 bar economically applicable - high performance in a very compact unit resulting in space and cost savings - increased safety margin - savings on accessories as only few applications will require pressure reducing valves to protect the SM4 > - less load on the four-point 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...

- 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 > - the end angle can be re-adjusted at any time by ű 5- in conjunction with the adjustable drive shaft datum, it is therefore possible to adjust the initial and fi nal position of the total angle required - assuring positive power/torque transmission even at peak load conditions > - the axial force required for mounting the shaft on the hub can be...

The rotary actuator SM4 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...

SZZ5 25 10 20153010 fi gure-3 [ SZ - Locating pin ] [ ZN - Gear hub DIN 5480 (hollow shaft) ] > The locating pin SZ (fi g. 3) 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. Rotary actuators with a gear hub profi le as per DIN 5480 shor- ten the structural length of the total construction, or are used for if...

The angle of rotation can be adjusted individually with this option (fi g. 4), both over its total range of rotation and over a partial range (e.g. total angle 270 , desired partial adjustment of 180 RE to 270 ). To this end, the adjusting insert RE is simply screwed inwards or outwards to give the desired angle of rota- tion. The shaft goes all the way through, allowing control equip- ment to be fi tted. Adjustment is only possible in the unpressurised state. The total length of the rotary actuator is extended by this option, depending on the range of adjustment (see page 12). fi gure-4 fi...
