Select an actuator which has a rated capacity greater than the maximum load that may be imposed on it. b. The structure on which the actuators are mounted should have ample strength to carry the maximum load, and should be rigid enough to prevent undue deflection or distortion of the actuator supporting members. c. It is essential that the actuators be carefully aligned during installation so that the lifting screws are vertically true and the connecting shafts are exactly in line with the worm shafts. fter the actuators, shafting, gear boxes, etc, are coupled together it should be possible to turn the main drive by hand. If there are no signs of binding or misalignment, the actuator system is then ready for normal operation. d. The actuators should have a greater raise than is needed in the actual installation. Should it be necessary to operate the actuators at the extreme limits of travel it should be done cautiously. e. It is important that the lifting screws should not be closed below the specified closed height dimension of the actuators otherwise serious damage may result to the worm gear. hen lifting screw end stops are called for to prevent over-travel or loss of screw that should be treated as an emergency device only and must not be allowed to come into contact with the worm gears during normal working cycles otherwise serious damage will result to worm gears and bearings. f. The maximum worm shaft speed for these actuators should not exceed rpm. for heavy loads. efer to ndrives Ltd. for higher worm shaft speeds for lighter loads. g. The lifting screws should not be permitted to accumulate dust and grit on the threads. If possible, lifting screws should be returned to the closed height position when not in use. h. periodic check of backlash between lifting screw and worm gear is recommended to check wear on internal threads of worm gear acklash in excess of % thread thickness indicates that a replacement will be necessary to replace the worm gear and nut assembly when wear has allowed the worm gear and nut to close against each other making further adjustment impossible. i. The actuators are shipped packed with grease (unless otherwise called for) which should be sufficient for one month of normal operation. or normal operation they should be lubricated about once a month using one of the Extreme ressure reases or their equivalent. See ecommended Lubricants Table 1. j. or severe service conditions the actuator should be lubricated with a molybdenium disulphide type of grease about once a week. e recommend any of the greases indicated in ecommended Lubricants Table 2.

18 orm ear ctuator etric Series - achine Screw eneral Instructions for ST/S & 14 : 5kn & kn odel 2 Disassembly / ssembly instructions: a. Ensure that shell cap set screws ( 9 or ) are slackened back clear of drill dimples in shell (1) before unscrewing shell cap. (it may be necessary to tap shell cap loose). b. If actuators with keyed lifting screws are involved it will be necessary to remove the key (12) before the shell cap can be unscrewed. c. n some models it will be necessary to remove the worm shaft (3) before the worm gear assembly and lifting screw can be pulled clear of the shell. d. heck all parts for damage or excessive wear and replace where necessary. e. fter re-assembling the worm shaft assembly, strike each end of worm shaft sharply with a wooden or fibre mallet to seat bearings properly. (earings must be assembled with the shield facing outwards) f. hen re-assembling the worm gear and load bearings ensure that the bearings are fitted so that the plate with the smallest bore size fits over the worm gear spigot. g. The shell cap should be fitted after the worm shaft assembly has been securely clamped and with the worm gear assembly in position. Tighten the shell cap until a slight drag is felt on rotating the worm shaft by hand. or anti-backlash actuators the shell cap must be screwed up with the lifting screw inserted and only as tight as to allow the required backlash between lifting screw and worm gear or normal actuator operation the recommended backlash is.5mm (.2 ). h. Tighten shell cap set screws (9 or ). It way be necessary to drill new dimples in the shell if new parts have been fitted or if readjustment for wear is necessary. i. or keyed actuators it is recommended that the lifting screw be threaded into the worm gear as far as required before fitting the key (12) 3 Instructions for filling detachable ends on lifting screws: It is important that the detachable ends be securely fixed to the lifting screws and the following procedure should be adhered to. a. Thread the detachable end on to the lifting screw and tighten up as hard as possible without damaging the components. b. Select a twist drill which is a free fit in the tapped holes of the detachable end. Using these holes as a drill guide, drill dimple only into the lifting screw. lean out swarf and remove detachable end. Select another drill which matches the set screw diameter and, using the drill dimples as a guide, drill into the lifting screw a full diameter depth of 1 mm below the root diameter of the threads. efit detachable end. c. it the knurled point set screws (supplied with detachable ends) firmly in place ensuring that point of set screws make contact with bottom of drill dimples. Secure the set screws with Loctite. d. If actuators with keyed lifting screws are involved, and it is required to line up the clevis flats or top plate holes, etc., in a fixed relationship to the worm shaft centreline, it will be necessary to face the underside of the detachable end to obtain the required relationship. This operation should be done carefully as only a few hundredths of a mm (thousands of an inch) removed from the attachment is equivalent to a fair amount of rotational movement. fter the correct relationship has been obtained with the attachment firmly tightened up, proceed as described in paragraphs b & c. ndrives Ltd. reserves the right to alter details and specifications without notice. Since special circumstances may affect the equipment s operation, users should consult the Technical Department at ndrives Ltd. or take other skilled engineering advice. It is recommended that the application design load is conspicuously displayed. T E H N I L
