Apparatus and method for measuring accelerating drum

摘要

A drum assembly for a vibratory compactor and method of retrofitting a vibratory compactor to measure the acceleration and/or vibratory movement of a drum rotatably mounted on the frame of the vibratory compactor. The drum assembly may comprise a drum including a shell, a mounting wall disposed inside the drum and a bulkhead disposed inside the drum and attached to the shell, a first bearing disposed between the frame and the mounting wall, a second bearing, a sensor, and a strap. The first bearing may include an inner race fixedly mounted to the frame. The second bearing may comprise a hub and a bearing shaft circumscribed by the hub and mounted to the bulkhead of the drum. The strap may be attached to the inner race and the hub.

1. A drum assembly of a vibratory compactor having a frame, the drum assembly comprising:
a drum rotatably mounted on the frame, the drum including:
a shell;a mounting wall disposed inside the drum; anda bulkhead disposed inside the drum and attached to the shell; a first bearing disposed between the frame and the mounting wall, the first bearing including a first bearing inner race fixedly mounted to the frame; a second bearing comprising a hub and a bearing shaft circumscribed by the hub and mounted to the bulkhead of the drum, the bearing shaft rotatable with the drum; a sensor mounted to the hub, the sensor configured to measure an acceleration of the drum; and a strap having a first end and a second end, the first end attached to the first bearing inner race, and the second end attached to the hub, the strap configured to allow movement of the hub with respect to the first bearing inner race; whereby vibrations from the hub to the frame are reduced.
