FENNER TYRE COUPLING CATALOGUE PDF

Both Martin Flex and Fenner Flex tyre couplings come with the convenience of Taper Bush mounting for fixing to the shaft. This allows the tyre coupling hub to be mounted against the bearing on a shaft, which will reduce overhung loads. Or the Taper Lock Bush is able to enter the hub from outside the coupling H Flange , which, in some applications, may assist with ease of installation. Please see pictorial configurations below. A feature offered by the Martin-Flex and Fenner Flex tyre couplings, which are not commonly available from other manufacturers, is the addition of a spacer unit accommodating for standard distances between shaft ends DBSE.

Both Martin Flex and Fenner Flex tyre couplings come with the convenience of Taper Bush mounting for fixing to the shaft. This allows the tyre coupling hub to be mounted against the bearing on a shaft, which will reduce overhung loads. Or the Taper Lock Bush is able to enter the hub from outside the coupling H Flange , which, in some applications, may assist with ease of installation. Please see pictorial configurations below. A feature offered by the Martin-Flex and Fenner Flex tyre couplings, which are not commonly available from other manufacturers, is the addition of a spacer unit accommodating for standard distances between shaft ends DBSE.

For further details, please refer to Figure 1 below. Figure 1 A further design option offered by both the Martin-Flex and Fenner Flex tyre couplings, again not provided by other manufacturers, is the addition of a fly wheel unit, which is designed to accommodate standard SAE flywheel designs and many other original equipment designs for combustion engines. These flywheel couplings use chloroprene flexible elements and employ standard F and H type driving flanges, as pictured below in Figure 2.

It can also accommodate simultaneous misalignment in all planes, without imposing any undue loads on adjacent bearings. This element meets the requirements of the Australian Fire Resistant Anti Static FRAS standards, set for rubber products that are designed to be used in flame proof environments. In addition to this safety factor, this material also has excellent resistance to contaminated environments including oil and grease. The Taper Bush should be cleaned to remove any grease, oil or contaminants.

The shaft and the bore of the tyre coupling hub, into which the taper bush is to be installed, also needs to be cleaned of oil, grease, dirt, or metal filings. It is a good idea to check both the bushing and the tyre coupling are free of nicks and burrs, and are not showing signs of cracking or damage. Place the taper bush in the tyre coupling hub, ensuring half holes are matched to make complete holes, taking note to match holes, and not threads.

Each complete hole must be threaded on one side only. To facilitate ease of fitment, all threads should be oiled, as well as the point of the set screws or threads.

Under the head of the cap screw should also be well oiled. Place the screws, but do not tighten, into the holes of the tyre coupling hub with threads on the hub side. Shown as in Figure 3 below. Figure 3 4. The taper bushing should be free in the tyre coupling hub. The assembly can then be located onto the shaft, into the desired position. Insert the required key into the keyway. Note that there must be an air gap between the top of the key and the taper bushing keyway. Check that there is no grease, oil, or lubricant between the outside surface of the taper bushing and the inside tapered surface of the tyre coupling hub, to which the bushing is being installed.

This outside surface must be completely free from any lubrication. Ensure the tyre coupling is located in the desired position. The required gap between the hubs is to be measured and set at the specified distance by measuring the assembled length across the hubs. Refer to dimension M in Figure 4 below. Figure 4 7. The screws now need to be alternately tightened to ensure taper bushing is pulled up evenly and squarely into the hub.

Correct seating of male and female tapers requires some attention to ensure they are seated squarely. This includes slight impact against the large end of the taper bushing. Tightening of these screws must, again, be done alternately to ensure correct seating of the taper bush squarely into the hub.

The torque setting information relative to each size taper bush is provided with the installation sheet in the packaging with new bushes. It is important that the slight impact applied to ensure correct seating is undertaken with a softer material against the face of the taper bush to prevent damage.
