High avaiabiity due to feibe moduar construction The smartfe couping stee beows and camping rings are the same for a designs with in an instaation size. They are adapted via reducing bushings to the required shaft diameter. These bushings can be engaged easiy and quicky into the camping rings. This concept guarantees you the owest possibe storage numbers and high avaiabiity.

3 Backashfree shaft coupings The Optimum Shaft Couping for every Drive Each drive has its own specific characteristics and therefore paces different demands on the coupings which transmit the torque from one shaft to the second and which compensate for the resuting shaft misaignments. In most cases ony backashfree coupings are abe to meet the requirements for highspeed, dynamic or reversing precision drives. Overview: Backashfree Shaft Coupings Types, Designs, Characteristics mayr power transmission has three of the most estabished and most attractive backashfree shaft coupings in its programme: Disk pack coupings, Stee beows coupings and Eastomer coupings Therefore, mayr offers an optimum soution for many different drives. primefe ROBA DS smartfe ROBA ES ROBA DS EAS controds ROBA DS Stee beows coupings Servo coupings Stee beows coupings Eastomer coupings Astee coupings Torque measurement coupings Astee coupings Feibe eement Stee beows Disk pack Stee beows Pastic eement Disk pack Disk pack Disk pack Nomina torque range in Nm Ma. permitted speed in rpm Shaft diameter in mm on request Ma. permanent operation temp. in C Torsionay rigid Torsionay feibe Vibration damping Can be combined with safety cutch Can be integrated with torque measurement Distance between shaft ends graduated variabe graduated fied variabe fied variabe Singejoint design Shaft misaignment compensation aia Shaft misaignment compensation radia Shaft misaignment compensation anguar Doubejoint design Shaft misaignment compensation aia Shaft misaignment compensation radia Shaft misaignment compensation anguar ATEX design acc. 94/9 EC Product cataogue P.933.V.GB K.950.V.GB K.932.V.GB K.940.V.GB K.950.V.GB K.950.V.GB P V.GB

Mutipy the operating torque with the vaues from Tabe 3 (temperature factor) and Tabe 4 (service factor) (interpoate the interim vaues). 2. Determining the coordinates misaignment : Determine the individua shaft misaignments in %, measured using the Permitted shaft misaignments for the intended couping size (see Technica Data, page 4). Eampe for size 2: 0,2 mm aia dispacement is 25 % of the permitted vaue 0,8 mm. Add together the individua percent vaues. The sum tota must be beow 100 %. 3. Write both the defined coordinate vaues into the respective diagram. The point of intersection must ie beow the characteristic curve of the intended couping size. 4. If the point of intersection ies above the characteristic curve, choose a arger couping, reduce the shaft misaignments or contact the manufacturers.

7 smartfe Short Description Couping Instaation For a detaied instaation description, pease see the Instaation and Operationa Instructions corresponding to the respective product B.9.8.GB. Important Instaation Guideines Wash off the conserving ayer in the bores with paraffin, white spirit, ceaner sovent or simiar. The bores and the shafts must be grease and oifree. The permitted shaft misaignment must not be eceeded. Avoid damage to the stee beows (1) before and during instaation. The camping ring (2) with the hoding spring (3) must be engaged in the reducing bushing (5) or reducing bushing with tapered bore (6). If a reducing bushing is dismanted or reinstaed more than 5 times, the snap ring groove may deform, making it unpermitted for use. In order to transfer the defined torques in Tabe 1 (page 5) correcty, the sots in the stee beows (1), camping ring (2) and reducing bushing (5) must be aigned (see Fig. 5). Couping Instaation Type (Fig. 1, page 4) and Type (Fig. 3, page 4) see aso Fig. 6 and Fig Pease ensure that the couping can be easiy pushed onto both shafts. 2. Push the entire couping over the whoe ength of the reducing bushing (5) onto a shaft. 3. Make sure that the stee beows (1) is pushed between the camping ring (2) and the reducing bushing (5) up to its imit, and that the sots in the stee beows, camping ring (2) and reducing bushing (5) are aigned (see Fig. 5). 4. Tighten the cap screw (4). The screw tightening torques (see Technica Data) must be observed. 5. Push the second shaft over the entire ength of the reducing bushing (5) into the couping. 6. Make sure that the stee beows (1) is pushed between the camping ring (2) and the reducing bushing (5) up to its imit, and that the sots in the stee beows (1), camping ring (2) and reducing bushing (5) are aigned (see Fig. 5). 7. Tighten the cap screw (4). The screw tightening torques (see Technica Data, page 4) must be observed. The sots in the stee beows (1), camping ring (2) and reducing bushing (5) must be aigned. On the reducing bushing with 4 sots, one of the 4 sots must aign with the sots in the camping ring (2) and stee beows (1).

If necessary, insert the key into the conica shaft. 3. Push the reducing bushing with tapered bore (6) onto the conica shaft. 4. Secure the hub a using a nut or a screw with press cover. 5. Push the rest of the couping with the open stee beows side up to its imit between the camping ring (2) and reducing bushing with tapered bore (6). 6. Tighten the cap screw (4). The screw tightening torque (see Technica Data, page 4) must be observed. 7. Push the second shaft over the entire ength of the reducing bushing (5) into the couping. 8. Make sure that the stee beows (1) is pushed between the camping ring (2) and the reducing bushing (5) up to its imit, and that the sots in the stee beows (1), camping ring (2) and reducing bushing (5) are aigned.
