Tenders are invited for Preventive maintenance of IMS 1A, 1B, 2A & 2B gearbox overhauling and inspection of IMS 1A, 1B, 2A & 2B drive and Non drive pulley
Check the drive pulley
to ensure that there is no build up.
The aircraft has a combination of 4-stroke piston engine and an electric motor that are coupled by the same drive pulley
that spins the propeller.
The larger drive pulley
removed 'belt slippage' previously the main cause of downtime and maintenance of the machine.
Polyurethane timing belts are positively driven because the toothed profile moulded directly into each belt, matches and engages directly with that of a toothed drive pulley
However, logic dictates that a smaller-diameter drive pulley
will have a much greater tendency to deflect as the conveyor width increases (a 1.
In order to get it as compact as it is (down 10% in size and 13% in mass compared with previous CVT), it was necessary to use a planetary gear set in an auxiliary gearbox because the dimension of the final drive pulley
would have been too large for the packaging space.
This new system enhances the durability of the drive belt and allows for a more compact design with a shorter distance between the drive pulley
and driven pulley.
Completely enclosed stainless steel motor drive pulley
ensures drip-proof, trouble-free operation
Ajusta-Bows are available in diameters up to 71/2 with a full range of cover compounds, pedestal or flange mounts, as well as an optional drive pulley
The patent-pending design of the Arrowhead ceramic lagging is said to provide solutions to problems experienced with conveyor belt slippage around the drive pulley
and severe wear problems on snub and bend pulleys.
These gearboxes are connected to two timing belt drive pulley
