Construction The liner heds use reduction gers to reduce motor speed nd increse motor torque, while the rck-nd-pinion converts rottionl motion into liner motion. The rck-nd-pinion mechnism is relible nd low cost method for converting rottionl motion into liner motion. System Composition Liner Heds Progrmmble Controller Rck Dog (sold seprtely) Motor (sold seprtely) Rck Grommet Limit switch Ger unit Motor (sold seprtely) Rck-nd-pinion unit Ger Unit Rck Cse Pinion The direction of rck movement is determined by the direction of motor rottion. When the rck reches either end, it is necessry to reverse the direction of rck movement by chnging the direction of motor rottion. Since the product does not hve n utomtic stop/reverse mechnism, it is necessry to ttch limit switches or sensors to chnge the motor rottion. Motor Unit The idel wy to chnge the direction of rck movement instntneously is to use reversible motor. Rck Solid-drwn S45C steel is ger-cut nd given nitride finish to reduce sliding friction nd provide rust-resistnce. Rck Grommet The rck is supported by two grommets mde by n oilless metl. If the end of the rck should dvnce into the rck cse nd the rck is supported by only one grommet, it might cuse the mechnism to mlfunction. The rck movement should lwys be reversed before the edge of the rck reches the rck grommet. The liner heds come with rck-nd-pinion unit nd reduction ger unit. Motors nd dogs re sold seprtely. Liner heds my be combined with ny stndrd AC motors. Any limit switches vilble on the mrket cn be used. Three rck speeds re vilble for given frme size, by chnging on the speed reduction rtio. The rck movement is controlled using brke pck, progrmmble controller or relys. Rck Ply The rck of the liner hed is supported t two plces by oilless metl grommets in the rck cse. Becuse the rck psses through the inside of the grommets, slight gp hs been left between the grommet nd the rck. Therefore, the rck is subject to ply s shown in the figure below. Direction A or B Direction C.79 inch (2mm) mx..2 inch (.5mm) mx. Ply in directions A nd B hs been mesured t point from the cse surfce. Since the rck is round-shped, ply in the D direction is lrge.

"Chrcteristics" of Liner Motors nd Liner Heds Rck moving speed, thrust force nd holding force re importnt fctors to consider when selecting liner motors or liner heds. Rck moving speed The rck speed for the liner motor is given in the tble of specifictions for ech product. Rck speed is expressed s "bsic speed". The bsic speed is clculted on the bsis of the synchronous speed of the motor (i.e. 18r/min t 6Hz). In ctulity, however, the speed of the motor vries with the lod. The bsic speed of liner hed cn be clculted from the motor speed, by using the following eqution. V N s 1 6 1 D p i V : Rck moving speed [inch/sec.] Ns : Speed of motor used [r/min] i : Rtio of ger unit on the liner hed (see tble below) Dp : Pinion pitch circumference [inch] (see tble below) Thrust force In liner heds, the following eqution is used to clculte the thrust force from the torque generted by the motor used. W T m i 1 2 D p 2 W : Thrust force [lb.] Tm: Torque of motor used [lb.] i : Rtio of ger unit on the liner hed (see fble below) 1 : Trnsmission efficiency s determined by the ger rtio (see tble below) Dp : Pinion pitch circumference [inch] (see tble below) 2 : Trnsmission efficiency of rck nd pinion (=.9) Liner Hed Ger Rtio Trnsmission Pinion Pitch Dimeter efficiency i η1 DP inch.(mm) LB (F) 2N- 3.66 LB (F) 1N- 5.66.295 (7.5) LB (F) 5N- 1.59 2LB (F) 5N- 17.68.73 2LB (F) 25N- 35.36.66 2 2LB (F) 1N- 86.91.59 4LB (F) 45N- 36.73 4LB (F) 2N- 75.66.837 (21.25) 4LB (F) 1N- 15.66 5LB (F) 45N- 36.66 5LB (F) 2N- 9.59.945 (24) 5LB (F) 1N- 18.59 5LB (F) 45U- 36.66 5LB (F) 2U- 9.59.945 (24) 5LB (F) 1U- 18.59 The vlue of the lod is determined using the eqution ssumes tht the rck is moving horizontlly. If it is moving verticlly, subtrct the mss of the rck from the vlue contined in the chrcteristics tble. Holding torque The following eqution is used to clculte the holding force of the liner hed when connected to motor. F B T B i 2 D p FB : Holding force [lb.] TB : Holding torque of motor used [lb.] i : Rtio of ger unit on the liner hed (see tble bove) Dp : Pinion pitch circumference [inch] (see tble bove) The holding force is the vlue when operting the rck in horizontl direction. The holding lod tht cn be driven when operting the mechnism verticlly is the mximum thrust force less the rck weight. Opertion Controlling motion of rck Linerheds re essentilly like in tht the rck is moved through the control of motor. Blocking the opertion t the end of the rck in order to stop the motor will not only pply n excessive torque to the gers, but will lso result in n inertil shock, reducing the life of the gers substntilly. Tke specil cre never to stop the motor in this wy. Use t less thn the mximum permissible thrust force The thrust force of liner heds vries with the bsic speed (determined by the ger rtio of the gerhed), with thrust force becoming lrger t lower speeds (greter ger rtio). This increse in thrust force is limited, by the mechnicl strength of gers or shft. Permissible thrust force is determined by tking into considertion the motor torque nd the mechnicl strength of the shfts nd gers, then dding sfety mrgin. If lod greter thn this vlue is pplied, or rck movement is locked for long time, it is likely to result in dmge to the rck-nd-pinion or ger unit. Mintin overhung lod within permissible level The mount of overhung Iod tht cn be pplied to the rck is determined by the totl lod on the rck bering. Operte rck t lods within the limits given in the following tble. Rck Stroke inch. (mm) unit=lb.

When the ctul usble rnge is shorter thn the rck stroke, lod up to the permissible vlue for tht length stroke cn be pplied. Rck Lubriction Some sort of lubricting gent is necessry to prevent friction when the rck psses through the rck grommet. The surfce of the rck nd ny gers tht mesh with the pinion should lwys be kept lubricted. In our products, since the rck cse is filled with lubriction gent, there is no need to lubricte the rck cse. However, ensure tht the surfce of the rck or ger teeth do not become dry, s operting in this condition will shorten the product's life. Use n electromgnetic brke motor for verticl opertion Opertion using verticl motion, such s in elevtors, often requires tht the lod be held in position t mid-stroke. For such pplictions, model equipped with n electromgnetic brke, which offers high holding power, is recommended. The electromgnetic brke motor hs the strongest holding power of ll stndrd AC motors. These electromgnetic brkes re power off brkes tht re engged in the event of power filure. A-23 2-21 ORIENTAL MOTOR GENERAL CATALOG
Instlltion of the lod to the end of the rck When connecting the lod using the tpped hole on the end of the rck, so tht rottionl force is not pplied to the rck. Hold the rck with wrench while tightening the screw. Glossry Liner Heds Wrench Flt Fce Connecting Liner Heds As the figure below shows, liner hed is connected to motor using the recessed res on ech unit s guides. Gently slide the liner hed from side to side without forcing the pinion shft ginst the plte on the liner hed or ginst the ger itself. Pinion Shft Hexgon Wrench Permissible Thrust Force This is the mximum thrust force tht cn be used when the motor is operting. For exmple, if there is thrust force of 154lb. (7kg), objects up to weight of 154lb. (7kg) cn be lifted. Holding Force This is the force required to hold the rck t the position where it hs stopped. If the mechnism is being used for verticl movement, this force must be ble to hold lod fstened to the end of the rck to prevent it from flling. Bsic Speed This is the rck speed tht is given s the bsis for the selection of liner heds. The vlues indicted re clculted on the bsis of the synchronous speed (i.e. 18r/min t 6Hz) of the motor. However, the ctul speed of the motor fluctutes ccording to the size of the lod nd cn rnge from 2% to 2% less thn the bsic speed. Mting Surfce Ger Unit Stroke This is the distnce tht the rck cn move. The full length of the rck is this distnce plus the width of the rck cse. Flnge Surfce Pilot Section Mximum Overhung Lod This is the lod tht cn be pplied to the rck in direction perpendiculr to the rck xis. If lod is pplied continuously to the end of the rck, then the weight of tht lod will be pplied to the rck s n overhung lod. Note: Attempting to put motor nd liner hed together by force cn result in dmge to the liner hed. Stroke Totl Rck Length Overhung Lod Dog The function of dogs is to trip limit switches nd sensors. Dogs re ttched to the rck to set the position where the rck should stop. Rck A gercut rod is mde of S45C or equivlent grde of steel.
