Forced-lubricating-and-cooling on-shaft oil distributor structure

Abstract

The invention discloses a forced-lubricating-and-cooling on-shaft oil distributor structure. An oil distribution shaft is arranged in a shell; two ends of the shell are fixedly connected with the oildistribution shaft through framework sealing flanges; framework sealing plates are arranged between the framework sealing flanges and the oil distribution shaft; leakage cover plates are arranged on the outer sides of the framework sealing plates; a back-up bearing is arranged between one side of the inner wall of the shell and the oil distribution shaft; an ahead bearing is arranged between the other side of the inner wall of the shell and the oil distribution shaft; a lubricating oil cavity is arranged between the inner wall of the lower part of the shell and the oil distribution shaft; a lubricating oil inlet is formed under the lubricating oil cavity; an inner oil pipe is arranged in the oil distribution shaft; support blocks are arranged on two sides of the inner oil pipe; a pin shaftis arranged in the middle of the inner oil pipe; two ends of the pin shaft are arranged in the oil distribution shaft through pin shaft liners; a third inner cavity is arranged among the ahead bearing, the back-up bearing, the shell and the oil distribution shaft; and a floating limiting assembly is arranged under the shell. According to the forced-lubricating-and-cooling on-shaft oil distributorstructure provided by the invention, high-pressure ahead oil, high-pressure back-up oil and low-pressure lubricating oil are provided, and the three ways of lubricating oil jointly lubricate and coolthe ahead bearing and the back-up 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...

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 propulsion shafting
