Abstract
A vibratory mechanism having a first eccentric weight coaxially rotatable with a second eccentric weight and a clutch operatively connecting the first and second eccentric weights. The clutch allows for co-rotation of the first and second eccentric weights and the ability to index the first eccentric weight relative to second eccentric weight to vary the vibrational amplitude.
Claims21
A vibratory mechanism comprising:
- a first eccentric weight rotatably supported within a housing;
- a second eccentric weight being coaxially rotatable with said first eccentric weight;
- and
- a clutch operatively connecting said first and second eccentric weights, said clutch being operative to index said first eccentric weight relative to said second eccentric weight to change a vibration amplitude of the vibratory mechanism.
1 more element
A work machine comprising:
- a compacting drum supporting said work machine;
- a vibratory mechanism coaxially positioned within said compacting drum;
- said vibratory mechanism including:
- a first eccentric weight rotatably supported within a housing;
- a second eccentric weight coaxially rotatable with said first eccentric weight;
- and
- a clutch operatively connecting said first and second eccentric weights, said clutch being operative to index said first eccentric weight relative to said second eccentric weight to change a vibration amplitude of the vibratory mechanism.
4 more elements
A method for controlling amplitude of a vibratory mechanism, the vibratory mechanism having first and second eccentric weights coaxially rotatably coupled by a torque limiting clutch operatively connecting, comprising:
- abruptly changing a speed of one of the first and second eccentric weights to cause the torque limiting clutch to slip, thereby causing the first and second eccentric weights to move farther apart or closer together to change the vibration amplitude.
