Abstract
Gear wheel that is provided with spokes (17) which extend between a rim (16) supporting a gear mesh (15) and a corresponding gear hub (18), whereby free spaces (19) are located between the spokes (17) which extend between the rim (16) and the gear hub (18), characterised in that at least one of said free spaces (19) is filled with a block (20) made of a rigid, incompressible material, whereby between the gear wheel (10) on the one hand and the block (20) on the other hand a viscoelastic material (21) is located.
Claims28
A gear wheel with at least one dampening block that can be used for a gearbox or gear transmission comprising:
- the gear wheel provided with spokes (17) which extend between a rim (16) supporting a gear mesh (15) and a corresponding gear hub (18), whereby free spaces (19) are located between the spokes (17) which extend between the rim (16) and the gear hub (18), wherein at least one of said free spaces (19) is filled with the at least one dampening block;
- the at least one dampening block comprising a block (20) made of a rigid, incompressible material and a viscoelastic material or a viscous fluid,
- wherein the viscoelastic material or a viscous fluid is located between the gear wheel (10) and the block (20) at least partially in a recess provided in the block.
