The Company Cross & orse was established in 14 through the amalgamation of two long standing and well respected companies in the Power Transmission Industry, T.D. Cross and orse Chain. T.D. Cross & Sons was founded in in Birmingham, concentrating in the production of bicycle components under the direction of the Cross family. They moved to the current factory site in 19 and developed into production of a popular range of roller chain sprockets and gearing. The competitive pricing and quality of product soon established the Company as a major supplier to both Agricultural and Industrial markets. The orse Chain Company was founded in 94 also for the manufacture of bicycles in Pennsylvania, U.S.A. The company moved into production of inverted tooth chain drives and established a manufacturing plant in London in 7, moving to the new Garden City of Letchworth, Herts. in 19. The product range in the U.K. was developed to include Roller Chain and Sprockets, Couplings, Limiters, Sprag Clutches and Timing Belt Drives, whilst in the U.S.A. by acquisition orse also included the Denver Gearbox Range and the Sealmaster Bearing Products. In 17 Cross & orse closed the Letchworth plant and centralised all production at the 10,000 sq. metre factory in Great Barr, Birmingham where current production of Roller Chains, Sprockets, Gears, Timing Belt Pulleys, Limiters, Sprag Clutches and other specialised power transmission equipment is undertaken. In addition to manufactured products, Cross & orse are main agents for orse-emerson, U.S.A.; and Stieber ormsprag, Germany; providing an extensive range of power transmission products. The company operates a policy of continued assessment to develop and improve its products and customer service. In pursuance of these objectives Cross & orse has been successfully assessed by Lloyds, and is registered, as an approved manufacturer of power transmission products to BS EN ISO 01.

Clamping Elements Tel: + 1 3 01 ax: + 1 3 1079 Email: sales@crossmorse.com Cross Clamping Elements provide the latest technology in drive connection. Cross Clamping Elements, by means of frictional forces, provide connection of all types of transmission equipment to their respective shafts, enabling transmission of both torque and axial thrust loads. Precision tapered thrust cones within the clamping elements create high pressure between shaft and hub to securely fasten pulleys, sprockets, gears etc. Stresses in both hub and shaft are similar to heavy press fits, however, the actual stresses are easy to calculate; and the hub can always be easily dismantled without damage to it or the shaft; only a torque wrench being required for both assembly and disassembly. Precision transmission of torque with no backlash is obtained with shaft clamping elements, without the need of tight manufacturing tolerances of mating components. Simplified designs can enable manufacturing cost reductions, coupled with easy assembly and disassembly. Cross Clamping Elements provide an alternative method of connecting hubs to shafts to:- Tapered Bushes Hydraulic Clamping Systems ine-bored s, with Precision keyways and Locking Setscrews Heavy Press its Welded Components Cross Clamping Elements offer many advantages:- Easy Assembly - to shaft connection is simple, only a torque wrench being required for correct assembly. Easy Disassembly - Just release of locking screws is all that is required on some series, others require simple positive release by tightening screws in jacking holes. Simplified anufacture - Parallel boring of hubs with H8 tolerance, or up to H11 on some sizes. Lower Cost Assemblies - Eliminates costly machining of splines, keyways, and setscrews. Long atigue Life - Elimination of keys prevents failure due to fretting, or notch initiated cracking under torsional loads. No Location Required - s can be positioned anywhere on shaft and locked to withstand high axial loads. High Transmission - ost series will transmit torques equivalent to shaft capacities, and for higher torques clamping elements can be combined within one shaft/hub connection. Small Diameters - Elimination of keyways often enables smaller diameter shafts to be used on many applications. reedom from Wear - Lack of moving parts means no wear. Clamping Elements can be tightened and released as often as required with no wear. Less aintenance - Correctly assembled, Clamping Elements require no maintenance. Self locking action of most designs ensures torque transmission even if locking screws should vibrate loose during use. True Running - Equally distributed friction locking ensures no play and high concentricity. s Remain Unmarked - Clamping Elements do not mark shafting ensuring ability of easy disassembly and assembly of components. Timing of Drives - Infinitely variable angular positioning with simple clamping and release enables simple timing of drives. Overload Protection - If design load is exceeded the clamping elements will slip on shaft providing protection to other machine components. Resistance to Contamination - When fully clamped contact surfaces are tightly pressed together preventing ingress of dirt and moisture. Sealed Joints - Clamping Elements Series RCK can be used to provide fully Gastight Joints, to seal against passage of liquids or gases. 2

Cross Clamping Elements In order to make the best selection of a Cross Clamping Element for your application a number of factors must be taken into consideration. These include the shaft diameter; the outside diameter of the hub of connecting component; the drive torque to be transmitted, and axial thrust loads, and tilting or bending loads, maximum shaft speeds, operating temperature, and general design parameters and space restrictions. Diameter:- The shaft diameter will determine the particular size of clamping element in any series, and by reference to the catalogue details the suitability of that to meet the other parameters can be checked. Also hollow shafts must be checked for any load carrying strength, see below. Outside Diameter:- The Diameter has to be sufficient to support the stresses imposed by the shaft clamping element. The catalogue gives maximum hub diameters for medium carbon steel, but for other materials and method of determining refer below. Generally if hub diameter is over 2.5 times shaft diameter all series are suitable, but for smaller ratios consider types RCK, ACE, CCE 54 and CCE, and for very thin walled hubs use types RCK 19, RCK and RCK. Determination of inimum Diameter and ax. Hollow Bore:- The following calculations are for static conditions only, considering only stresses imposed by the clamping element. The hub diameter is controlled by the pressure applied by the outer cone of the clamping element; the shape of the hub bore and total length of hub; and yield stress for permanent elongation of 0.2%. inimum Dia.

Product Pages Assembly Type B C=0.8 Hw 2L1 Hw 2L2 Assembly Type C C=0.6 Hw 2L1 (All Types) aximum Speed:- The centrifugal forces generated by high shaft speeds can reduce torque capacity and increase stress loads on hubs. Consult Cross & orse if speed of shaft results in outer clamping diameter D running above /sec. Operating Temperature:- aximum temperatures should not exceed C. At temperatures above C the locking screws should be rechecked after 1 hour operation, whilst assembly is still warm. Tel: + 1 3 01 ax: + 1 3 1079 Email: sales@crossmorse.com 3

The maximum Drive Tm must take into consideration any shock loads, and also the maximum starting torque of drive. If the max. torque is not known, it can be estimated by applying the service factor from the table below to the nominal drive torque Td, which can be derived from motor power P and shaft speed N r.p.m. Drive Td = 95 P Where P = Power kw N N = Speed rpm ax.

Suited to more general applications, this series provides medium torque transmission, which can be increased by mounting the unit in series. This type does not provide self centring, and therefore other methods of centring the hub to the shaft are required. The units do not move axially during clamping and generally self-release when clamping screws are relaxed. Recommended tolerances for full torque transmission are:- h9 H9 As both cones are split larger tolerances, up to h11/h11 can be accommodated, but with a reduction in torque capacity. Clamping surfaces to be finished to Rz 15 µm. If two or more elements are used in series the resultant torque will be proportionally increased.

The design offers the maximum versatility of design, but does require the customer to provide their own thrust ring assembly. Whilst only providing low torque transmission per unit they can be combined (up to 4 units) to increase torque capacity. When fully clamped these units provide excellent gastight sealing. any designs of thrust rings are possible and sketches to the left are two typical designs. These units do not self centre, so require external means of centring the hub.

Clamping Elements Types CCE 54 and CCE Part No. d D D2 L These clamping elements use a single lock nut to apply the clamping pressure, thereby enabling quick assembly and removal. The lock nut can be secured in postition by bending over a tab of lock washer. The thin walls of the clamping cones, combined with low hub pressures enables use with soft materials, such as aluminium, and small hub diameters. Use type CCE 54 where axial space is restricted and torque is low. Type CCE is for higher torque transmission.

Clamping Elements Type RCK Tel: + 1 3 01 ax: + 1 3 1079 Email: sales@crossmorse.com Part No. No need for a Wrench with these Clamping elements, just tighten the screws in clockwise sequence in stages until the front faces of the flange and outer ring are aligned. This allows the transmission of torque values shown in the table. This overcomes the problems often encountered where units are either under or over tightened causing failures in transmission. There can also be a time saving in that powered tools can be used for the belt tightening. Increased torque capacities are achieved by the use of larger screws. The single block design automatically provides parallel setting of the parts, thereby reducing the need for dynamic balancing.

Similar in design to the Clamping Discs, type RCK 19, but with the discs spaced further apart to enable connection to more than one shaft, enabling use as a rigid shaft coupling. These units can be used to connect two identical diameter shafts which are perfectly aligned, or to produce a longer shaft which is only mounted in two bearings. capacities are suitable for standard shafting. These units provide zero backlash shaft connection with advantage of fast assembly and disassembly. The design makes the unit equally suitable for horizontal and vertical shafts, capable of withstanding high axial loads.

Disassembly:- The taper of the individual rings is such that the assembly should automatically release when the locking screws are slackened. If not light tapping on the hub circumference should release them. Types CCE 54 and Installation:- 1. Clean all contact surfaces, and lightly oil with clean unmodified mineral oil.* 2. Turn locking nut anticlockwise until outer sleeve loose on inner cone. 3. Position hub on shaft and insert clamping element. 4. Align hub and tighten locking nut to catalogue torque value, and bend suitable tab on lock washer to prevent further rotation. Disassembly:- 1. Release bent washertab and undo nut until sleeve loose. 2. Remove clamping element, If tight give end of tab gentle tap to release. Types RCK 19/ and 95 Installation:- 1. Clean all contact surfaces, and lightly oil with clean thin unmodified mineral oil.* 2. Slacken all clamping bolts by a couple of turns. 3. (RCK 19/ only) it clamping element on outer diameter of hub, and slide assembly onto shaft and position. (RCK 95 only) it shaft ends equally into clamping element ensuring small clearance between shafts. 4. Tighten all bolts in a diametrically opposite sequence, in several stages up to max. specified torque. 3 7 9 5 2 1 6 10 8 4 Disassembly:- Slacken all bolts and gently tap on bolts to release clamping element. *WARNING: Never use, lubricant containing olydenum or E.P. additives, synthetic lubricant, or grease.
