Gear box lining reinforcing structure of vibration hammer

Technical Field

The utility model relates to a vibratory hammer gear box technical field, more specifically say, are a vibratory hammer's gear box inside lining additional strengthening.

Background

The gear box is an important component in the vibratory hammer, and the gear box body far away from one side of a driving source needs to bear higher load when the conventional gear box works, so that the gear box body far away from one side of the driving source is easy to break, and the service life of the gear box can be influenced.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to provide a gear box inside lining additional strengthening of bobbing hammer, it is through behind the welded fastening welt on the inner wall of the gear box of keeping away from driving source one side, can effectively improve the structural strength of the gear box of keeping away from driving source one side to can effectively improve the life of gear box.

The technical scheme of the utility model is that, a gear box lining reinforcing structure of a vibration hammer with the following structure is provided, which comprises a gear box body, wherein a lining plate is welded and fixed on the inner wall of one side of the gear box body, which is far away from a driving source, second shaft holes which are arranged in one-to-one correspondence with first shaft holes in the gear box body are arranged in the lining plate, each second shaft hole is coaxially arranged with the first shaft hole in a corresponding position, and the inner diameter of each second shaft hole is the same as the inner diameter of the first shaft hole in the corresponding position; be provided with the groove of stepping down that is arranged in dodging the oil extraction hole in the gear box body in the welt.

The utility model discloses a gear box lining reinforcing structure of a vibratory hammer, wherein, the inner end surfaces of the lining plates above and below each second shaft hole are provided with oil passing grooves, each oil passing groove is communicated with the second shaft hole at the corresponding position, and one end of each oil passing groove far away from the second shaft hole extends to the edge of the lining plate; through the setting of oil groove, when the gear box was in operation, the lubricating oil that is located the welt can conveniently reach second shaft hole department through the oil groove.

The utility model discloses a gear box lining reinforcing structure of a vibration hammer, wherein each oil passing groove extends along the vertical direction; by adopting such a structure, the structural strength of the lining plate can be improved.

The utility model discloses a gear box lining reinforcing structure of a vibration hammer, wherein the inner wall surface of each oil passing groove is an arc surface; after the oil passing groove with the structure is adopted, the oil passing groove has the advantage of convenience in processing.

After structure more than adopting, compare with prior art, the utility model discloses a behind the welded fastening welt on the inner wall of the gear box body of keeping away from driving source one side, can effectively improve the structural strength of the gear box body of keeping away from driving source one side to can effectively improve the life of gear box.
