» Gear Couplings Dentex ® torsionally rigid, power transmission couplings which transmit torque between two steel gear hubs and the internal toothing of a nylon drive sleeve. The gear coupling is designed to relieve neighbouring shaft bearings from non-controlled additional bearing loads. Maximum shaft diameters of 100 mm can be accommodated with maximum torques up to 2,400 Nm and speeds up to 8,000 rpm. Single or double engagement options suit a variety of applications. » Continuous sleeve or flanged connections for high power drives. » Vari-Crown tooth form has higher tooth strength when...

Specialist power transmission supplier jbj Techniques Limited, of Redhill, Surrey, were recently contacted by the staﬀ of Bloodhound SSC R&D engineering team to solve a problem on the fuel pump test rig. jbj Techniques had worked with various team members in the past and this previous experience made ‘jbj’ an easy choice to assist with this project. The scope of supply was to produce a suitable drive coupling with a maximum diameter of 160mm which is capable of transmitting 550Nm @ 10,000 rpm, needed to be as short an assembly as possible and at the same time be able to accept misalignment...

The coupling under went dynamic balancing before delivery because of the high speeds it needed to perform at. The speciﬁcation was 550Nm at 10,000rpm and it had to be 160mm maximum diameter, as short as possible, ﬁt to an automotive output ﬂange and allow as much misalignment as possible. Not a job for a simple spider coupling! The Lovejoy ‘Sier Bath’ coupling was the perfect solution. Seen below mounted to the end-suction centrifugal pump. which contains the actual (solid) fuel (rubber). The other engine is a jet and does not require a separate pump. The end-suction centrifugal pump is...

Setting up test rig inside old MOD hangar in Newquay, Cornwall. Fuel tank. For the test it contains water to be pumped through at the same speed and pressure that fuel will be pumped during the actual land speed record attempt. This ﬂange connects to the pipeline seen here above. This is the fuel line.
