Claims

[Claims for Utility Model Registration] 1. A shaft 3 equipped with an eccentric weight 4 is rotatably supported in a casing 2 in which lubricating oil is stored. A vibratory pile driver having an exciter 1 configured to freely vibrate vertically to generate vibrations in a pile by rotation, a pair of left and right bearings 6, 6 provided at both ends of the shaft 3 and the casing 2. A cooling water flow path for cooling the lubricating oil inside the casing 2 is provided so as to flow from the one bearing 6 side to the other bearing 6 side via the lower part of the casing 2. A vibrating pile driver. 2 A shaft 3 equipped with an eccentric weight 4 is rotatably supported in a casing 2 in which lubricating oil is stored, and the rotation of the eccentric weight 4 accompanying the rotation of the shaft 3 causes vibrations in the pile. A vibratory pile driver includes a vibratory exciter 1 configured to freely vibrate vertically and an electric motor 13 for rotationally driving the shaft 3, a pair of left and right bearings 6 provided at both ends of the shaft 3. , 6, the lubricating oil in the casing 2, and the electric motor 1.
A cooling water flow path for cooling the electric motor 13 is provided so as to flow from the one bearing 6 side to the cover 14 side of the electric motor 13 via the lower part of the casing 2 and the other bearing 6. A vibrating pile driver featuring:
