LOW-NOISE HYDRAULIC HAMMER

摘要

The present invention relates to a hydraulic hammer, and more specifically, to a low-noise hydraulic hammer, wherein an impact bar that is accommodated inside of a piston is inclined so as not to contact the inside of the piston thereby preventing cracks, and a noise insulating material or a heat sink is installed inside the piston or outside the impact bar, thereby reducing noise and improving heat radiation performance.

主权项

1. A low-noise hydraulic hammer comprising:
an impact bar (200) formed in a striking part (300) and inserted into a receiving part (120) in a piston (100), wherein both inner lateral sides of the receiving part (120) are inclinedly formed such that a diameter of the receiving part (120) is increased toward the impact bar (200), and the impact bar (200) is received in the receiving part (120) to make contact with the piston (100), formed with a diameter reduced toward the receiving part (120), and spaced apart from the both inner lateral sides of the receiving part (120) by a specific distance.
