TE 33 Engine Tribometer
The TE 33 Engine Tribometer is a two-station, vertical axis, long stroke reciprocating tribometer, which combines the reciprocating drive mechanism from the TE 77 and DN 55.
The test assembly is located vertically above the reciprocating drive assembly and comprises two fixed specimen arms supported on flexural pivot bearings, which are in turn mounted on linear flexure assemblies. Motion in a vertical direction is restrained by piezo force transducers. As each arm reacts against its own independent transducer, the friction between the each moving specimen and each fixed specimen is monitored independently. This allows two different material pairs to be tested simultaneously under identical conditions of load and temperature.

TE 34 Piston Ring Micro-Welding Rig
The TE 34 Piston Ring Micro-Welding Rig is used for simulating the movement between the ring and the piston groove, which gives rise to problems of wear, scuffing, micro-welding and, in severe cases, seizure.
A motor driven, vertical axis, cam drive with a stroke of 3 mm, provides vertical reciprocation of a ring specimen holder at a maximum frequency of 20 Hz. The piston specimen holder is placed above the ring holder and locates on two linear shafts, restrained by springs. When the ring specimen strikes the piston specimen, the springs compress to provide the loading on the interface. The peak load is adjusted by pre-setting the spring compression.
Technical Specifications
- Ring direct up to 99mm
- Maximum load 300N (adjustable)
- Ring sample stroke 3mm
- Maximum operating frequency Maximum 20Hz
- Piston oscillation frequency is ±90° at 0.2Hz
- Ring sample temperature：Max 300℃

TE 35 Valve Impact Rig
The TE 35 Valve Impact Rig uses cams that are constant velocity over at least sixty degrees of rotation, with profiles designed to give variable velocity either side of TDC and BDC. Impact velocity, which, as with other rigs, varies with rotational speed, is essentially constant over a significant part of the valve motion.
The use of specially designed cams means that the maximum velocity of the valve never exceeds the required impact velocity.
The machine is mounted on a frame, which incorporates a control cabinet, hot air jet heating system and lubrication service module. The machine is mounted on rubber isolation mounts and comprises a variable speed a.c. motor connected via a flexible coupling to the test assembly camshaft.
Technical Specifications
- Maximum Rotational Speed: 3,000 rpm
- Maximum Impact Velocity at 3,000 rpm:
4 mm cam: 600 mm/s
6 mm cam: 857 mm/s - Maximum Valve Temperature: 450°C
- Maximum Seat Temperature: 350°C

TE 47 Three Station Ring/Liner Tribometer
The TE 47 allows multi sample testing of simple ring samples running against an unmodified cylinder liner. The key difference between this device and more conventional reciprocating tribometers is that instead of running up and down the liner, the samples are run around the internal circumference of the liner in either continuous rotation, allowing high sliding speeds to be achieved, or oscillating motion.
A complete (unmodified) cylinder liner sample is attached by means of an expanding collet to the test spindle. The lower end of the liner sample is supported by a steady bearing carried on a secondary cross-head. A spline shaft assembly, which mounts on the main cross-head, carries a ring sample carousel. The carousel is free to slide axially on, while its rotation is resisted by, the spline.

CD 105 Valve Train Wear Test Rig
The test rig is designed to run standard tests for the evaluation of automotive gasoline engine oils for wear characteristics of camshaft and rocker arm. In the configuration above the rig is fitted with a Toyota 3A engine. The rig comprises three modules, the engine unit, the service unit and the control unit.
The engine unit provides support for the engine and an electric motor drive system. The unit is floor mounting and has vibration isolation mounts. The standard drive system comprises an ac motor and drive belt to run at a nominal speed of 1000 rpm.
The service unit provides temperature control of the engine oil under test. Oil is drawn from the sump of the engine by a circulating pump and is returned to the sump via a heater and heat exchanger. Oil temperature control is achieved by electric heating and water cooling.
Technical Specifications
- Rotating speed：1,000rpm

CD 110 Transmission Test Rig
The CD 110 test rig is designed for endurance testing gearboxes for off road construction vehicles. The rig is of the recirculating torque type with two identical gearboxes of the user’s manufacture, one acting as the test box and the other as the slave box. The rig incorporates three other gearboxes, two each with two axles and one with three. One of the two axle boxes is trunnion mounted about one shaft. A servo controlled hydraulic ram fitted to a torque arm. provides the means to wind torque into the drive train by rotating the box about the trunnion axis. The torque can thus be varied as required while the drive is in motion.
A 150 kW thyristor controlled dc machine is provided for rotating the drive train and powering the losses. Typically, 400 kW of recirculating power can be produced, at drive input speeds up to 3000 rpm.
Technical Specifications
- Rotating speed：3,000rpm
