2 TECHNICAL DESCRIPTION General Swedrive mechanical screw jacks are produced in 6 different sizes, from 5 to 250 kn. Series production using advanced CNC equipment ensures constant high quality of the product. Screw jacks are manufactured in two basic varieties with either a trapezoidal or ball screw. Screws of the trapezoidal variety are self locking. Ball screw spindles are used for high speed applications, typically in excess of 2m/min, or for instance where the duty factor is high. The efficiency of a ball screw is greater than 90% which means that the efficiency of a screw jack is increased. Although this in turn implies less load on the drive motor, some form of braking arrangement must be incorporated. n n n n n n n Trapezoidal or ball screw. Screw jacks are sealed and filled with mineral grease. Only the screws require regular lubrication. Mounting may be horizontal, vertical or inverted. Several screw jacks can be coupled together with a common drive motor operating via right angle drives, couplings or intermediate shafts. The screw drive casing may be flanged to accommodate various types of electrical, hydraulic or pneumatic motor. All sizes are available as standard with a choice of 3 gear ratios. Various optional extras such as screw covers, swinging rear bracket, anti-rotation device, preloaded screw, screw guide collars, etc. Product range Electric motor Screw cover (Page ) Swinging rear bracket (Page 13.3) Hydraulic motor Pneumatic motor Screw jack Safety nut (Page 13.4) Anti-rotation lock (Page 13.4) Preloaded screw (Page 13.2) Screw guide (Page 13.1) Other options (Page ) 4.1

Other sizes in S.G. cast iron. All casings have mounting flanges on each side, allowing flexibility in choice of mounting options. Worm screw (input shaft). Manufactured from case hardened alloyed carburising steel. Both flanks of the thread are ground to the correct profile and high surface finish on a modern CNC automatic thread grinder, thus reducing friction losses to a minimum. Screws have right hand thread as standard. Worm wheel and nut are made of centrifugally cast special bronze. The teeth are machined to the required profile and surface finish in CNC gear cutting machines, assuring optimum power transmission efficiency in combination with the worm screw. Screw: Trapezoidal screws are made of high quality cold drawn steel and are precision roll formed which gives high accuracy in lifting and smooth thread flanks. The steel ball screw is cold rolled and induction hardened. Bearing arrangement: Input shafts of sizes 5, 15 and 25 are fitted with deep groove ball bearings. Other sizes incorporate double angular contact ball bearings and deep groove ball bearings. All sizes of screw are supported by thrust ball bearings. Seals: Input shaft has radial type sealing rings with lip. The output end of the screw is provided with a V-ring. Motor drive: All sizes can be coupled via a flange to various types of motor. This is achieved by using a separate adapter bolted to the jack casing. The motor then drives the jack via the protected shaft coupling inside the adapter. 4.2

Fa Fr Transverse forces Transverse loading of the screw should be avoided. Both trapezoidal and ball screws are designed to transmit longitudinal forces only. Transverse loads must therefore be accomodated by external support of the jack. Any radial stress on the screw will tend to reduce its service life.

6 TECHNICAL DESCRIPTION Lubrication Gear box; All gearboxes are sealed and filled with a mineral grease suitable for operating temperatures between -30 and +100 C. Regular checking is recommended to ensure adequate lubrication of the gear. Inspection may be made via the lubrication hole. Recommended greases: Klüber Centoplex H0 (M-00) Shell Tivela Comp A (S-00) Mobil Mobilplex 44 (M-00) or equivalent Screw; It is important to avoid any metal-to-metal contact between the threads of the screw and nut. Before delivery, the screw is therefore coated with a special lubricant which ensures adequate lubrication from the outset. The screw should subsequently be checked at regular intervals, depending on the application. See under "Maintenance". Recommended greases: Klüber Duotempi PMY45 (S-3) : not suitable for ball screws Shell Grease 1352 CAE12 (M-2) Shell Limax EP2 (M-2) Shell Retinax MS (M-2) BP Energrease LS-EP2 (M-2) Mobil Mobilux EP2 (M-2) or equivalent Note.: Letters and figures in parentheses denote the following: S = synthetic oil base; M = mineral oil base; Figures denote consistency according to DIN Warning!

7 MOUNTING INSTRUCTIONS Mounting instructions 1. When mounting, ensure that the mounting surface is at right angles to the axis of the screw. The surface must be firm, clean and level, in order to avoid internal stresses in the casing. 2. Screw jacks should be protected against transverse load. The load should therefore be suitable guided so that only tension or compression loads are allowed to act on the screw. See page 4.4! 3. Although the jacks are suitable for inverted use, mounted on a backing plate, the force on the jack should preferably act towards the plate. See fig! 4. Screw jacks should not be mounted in such a way that the load is carried by the fixing bolts or, in the case of ball screw models by the ball screw nut thread. See fig! 5. For ball screws, follow mounting instructions as supplied. 6. With combinations of several screw jacks comprising motor, differential gear and intermediate shaft, careful alignment of the system is required. 7. On a correctly mounted jack or combination of jacks, it should be possible to turn the input shaft freely when no load is applied. 8. Ensure that the screw is never fully screwed in to the end of its travel, otherwise damage may result. Approx. 5 mm of thread should be visible outside the jack. N.B. Standard screw jacks are not suitable for equipment used for personnel transport, for special needs contact us. Not recommended Recommended Care and maintenance 1. Keep the screw free from dust and dirt. The screw jack can be fitted with various types of shield to protect against contamination. See page ! 2. Do not forget to keep the screw well greased. With occasional use, the greasing interval should be once per month. If used daily, checks should be made weekly and grease added as required. Running in Where feasible, it is advisable to limit the load to one half of the nominal rating at the start of operation. After this initial period, the load may be increased. 5.1

8 SELECTION OF A SCREW JACK Formula for calculation of motor drive power: To determine the correct size of screw jack it is necessary to know the load and required lifting speed. A significant proportion of the applied power is used in overcoming the friction between the trapezoidal screw and nut. These losses are converted into heat, and therefore either the speed, load or duty factor must be limited in order to avoid overheating of the screw jack. For this reason ball screw jacks can be used either at higher speeds or for higher duty factors. For screw jack arrangements in which several screw jacks, differential gears, couplings etc. are combined, regard must be paid to losses in the various elements and to alignment errors.

30 SCREW COVERS Leather bellows For protection of the screw against contamination. With lengths over 0,5 metre, a limiting device and supporting rings should be fitted. The limiting device and supporting rings doesn't effect the length but are included in the 15% additional length acc. to table below. Types A, AK When fitted with bellows, the effective stroke is reduced by the minimum length of the bellows (i.e. fully compressed). Dimensions H2 and H21 in the dimension tables to maintain the full stroke (pages 9.2, 9.4, 9.6, 9.8) are increased in accordance with the able below: Types AL, AKL * One or two bellows - depending on whether bellows are mounted on both sides or only one side of the nut. Additional length for types Size D1 D2 A,AK AL,AKL ,15xSL *One shield 0,15xSL *Two shields 0,3xSL 10.1

31 SCREW COVERS Spiral spring cover For protection of the screw against contamination and damage. The shield is guided by special flanges as it extends or retracts. With vertical mounting the larger diameter should be uppermost. The shield requires no maintenance but, in a heavily contaminated environment, it should be regularly wiped clean and lightly oiled. Types A, AK When fitted with covers, the effective stroke is reduced by the length of the cover when retracted (i.e.fully compressed), plus the length of the guide flanges. Dimensions H2 and H21 in the dimension tables for screw jacks should be increased by the amounts indicated in the table below. Types AL, AKL Note: For types AL and AKL, the increase refers to one cover. Where covers are mounted on both sides of the nut these values should be doubled.
