Oil-water dual-purpose fluid coupling with brake drum

Abstract

The invention discloses an oil-water dual-purpose fluid coupling with a brake drum. The oil-water dual-purpose fluid coupling comprises a connecting disc and the brake drum; the connecting disc and the brake drum are respectively matched with a power machine shaft and a working machine input shaft to be mounted on the same axis; one end of the connecting shaft is mounted opposite to a claw of the brake drum; an elastic block is arranged between the connecting shaft and the brake drum; the two ends of a rear auxiliary cavity are respectively connected with the connecting disc and a pump impeller; the rear auxiliary cavity, the pump impeller, a housing (or a side auxiliary cavity) and a sealing gland are provided with anti-fall off spring oil seals and are sealed with excircle of a main shaft; the sealing gland is mounted on the housing, and used for pressing a bearing on the main shaft; a spigot of the rear auxiliary cavity is mounted on the pump impeller, and used for pressing another bearing at the other end of the main shaft; liquid injection plugs are arranged on the pump impeller, and screw holes in the liquid injection plugs are communicated with the pump impeller; a fusible plug and an explosion-proof plug are arranged in the housing (or the side auxiliary cavity), and screw holes in the fusible plug and the explosion-proof plug are communicated with the housing; lips of the oil seals are respectively sealed with the excircle of the main shaft; a working cavity is oblate. The oil-water dual-purpose fluid coupling has the advantages that various liquids can be used, and the use is convenient.

Description

technical field [0001] The invention belongs to the technical field of hydraulic transmission, and in particular relates to a dual-purpose hydraulic coupling for water and oil with brake wheels. Background technique [0002] The principle of the hydraulic coupling is: the hydraulic coupling is installed between the power machine and the working machine and forms a transmission system device with it. The input end of the hydraulic coupling is connected to the power machine, and the brake wheel at the output end is connected to the working machine. When the power machine drives the coupler pump wheel to rotate through the output shaft, the liquid filled in the working chamber is thrown from the pump wheel to the turbine under the double action of the centrifugal force and the working impeller, driving the turbine to rotate, and at the same time driving the working machine to rotate to output power. That is, the pump wheel obtains the mechanical energy of the power machine and...
