A Shaft Oil Distributor Structure with Forced Lubrication and Cooling

Abstract

The invention discloses an on-axis oil distributor structure with forced lubrication and cooling. The oil distribution shaft is arranged in a housing, and both ends of the housing are fixedly connected to the oil distribution shaft through a skeleton sealing flange. There is a skeleton sealing plate between them, a leakage cover is arranged on the outside of the skeleton sealing plate, a reversing bearing is arranged between one side of the inner wall of the housing and the oil distribution shaft, and a forward bearing is arranged between the other side of the inner wall of the housing and the oil distribution shaft , There is a lubricating oil chamber between the inner wall of the lower shell and the oil distribution shaft, the lubricating oil inlet is located below the lubricating oil chamber, the inner oil pipe is arranged in the oil distribution shaft, the inner oil pipe is provided with support blocks on both sides, and the pin shaft is set In the middle of the inner oil pipe, the two ends of the pin shaft are arranged inside the oil distribution shaft through the pin shaft bushing. There is a third inner cavity between the front bearing, the reverse bearing, the shell and the oil distribution shaft, and a floating limiter is set under the shell. bit components. The invention provides high-pressure front car oil, high-pressure reversing oil, low-pressure lubricating oil, and a common three-way lubricating oil to lubricate and cool the front car bearing and the reversing bearing.

Description

technical field [0001] The invention relates to the technical field of oil distributors, in particular to an on-axis oil distributor structure for forced lubrication and cooling. Background technique [0002] The oil distributor on the shaft of the marine adjustable pitch propeller is an important component to realize the oil supply to the adjustable pitch hydraulic cylinder. Generally speaking, the oil distributor is installed at the front end of the output shaft of the gearbox, but it is not available for low-speed diesel engines. Gearboxes and fixed propellers are generally not replaced when converting fixed propellers to adjustable propellers. The safety and stability of the oil pipe system of long-shaft adjustable propellers with too long internal oil pipes is poor, so it is necessary to use an oil distributor on the shaft to solve the problem of gearbox failure When installing the adjustable propeller oil distributor, install the oil distributor directly on the propuls...
