Problems solved by technology

Lack of lubrication increases bearing wear at the beginning of the next gearbox operation (after which the speed increases to operating speed, eg 1600rpm), often leading to early bearing failure, which in turn requires costly repairs and downtime of the pile driver

Embodiment Construction

[0009] figure 1 It is a schematic diagram of a routine vibrating pile driver system, and is shown in 10. It includes a conventional building crane 12 having an extended boom 14 and a control cable system 16. At the end 18 of the boom 14, the control cable extends down to the vibration pile driver assembly 17. The assembly typically includes suppressor 20, gearbox 22, and clamping system 24 and drive motor 26 for the assembly, usually hydraulic, although it can also be an electric motor. All of these components are routine, so there is no need to explain. The jig 24 clamps the gearbox and the suppressor to the pile 27 of the length L, which will be driven in the operation.

[0010] figure 2 A conventional vibration pile driver gearbox is shown. In general, the gearbox shown in 30 includes a housing 31 that is typically made of steel. Although the size of the housing can vary, the typical system will be 14 inches × 96 inch x 24 inches, which is merely exemplary. At the bottom of...

Abstract

A lubrication system includes a hydraulic cylinder pump which receives oil from the pile driver gearbox and an actuating mechanism connected to the pump to move oil therein through an exit line to a spray mechanism in the gearbox housing, providing lubrication to the gearbox bearings before the gearbox elements begin to operate.

Description

Technical field [0001] The present invention generally relates to a vibrating pile driver, and more particularly to a lubricating apparatus for vibrating the gearbox portion of the pile driver. Background technique [0002] In the operation of the vibrating pile driver, it is essential to properly lubricate the operating components of the gearbox portion of the pile driver, especially gearbox bearing to reduce wear and extend its operating life. In the past, the splash lubrication system has been used, and the oil level is selected at the bottom of the gearbox. Typically, the oil level is typically sufficient to allow eccentric components and / or gear gear to be lubricated in oil. In this system, when the motor (usually hydraulic motor) for the gearbox is operated, the weight and gear will begin to rotate. However, the gearbox member (including the bearing) is dry when operating at an opening. Until the eccentric or gear rotates a few turns to make the oil through and splash it ...
