an electromagnetic clutch

Abstract

The invention provides an electromagnetic clutch, belongs to the technical field of clutches and solves the technical problem that lubricating grease overflows easily due to the fact that excessive lubricating grease is poured into an existing clutch. The electromagnetic clutch comprises a shell, the shell is internally provided with a bearing chamber, and the bearing chamber is internally provided with bearings; the shell is provided with an oil injection hole in the radial direction of the shell, the bearing chamber is furthermore internally provided with an outer spacer bush, the outer spacer bush is internally provided with an oil storage cavity communicating with the interiors of the bearings, the outer surface of the outer spacer bush is provided with an oil guide channel communicating with the oil injection hole, and the outer spacer bush is provided with oil feeding holes connecting the oil guide channel and the oil storage cavity; and the oil injection hole and the oil feeding holes are formed in a staggered manner. The oil guide channel is arranged, the flowing path of lubricating oil or lubricating grease is greatly elongated, in this way, adhesive power is formed on the inner wall of the long oil guide channel through viscidity of the grease, oil injection pressure is increased, and the phenomenon that the grease overflows due to the fact that excessive grease is poured into the oil storage cavity is effectively prevented.

Description

technical field [0001] The invention belongs to the technical field of clutches and relates to an electromagnetic clutch. Background technique [0002] The clutch is similar to a switch, its active part and driven part can be separated temporarily, and can be gradually engaged, and it is possible to rotate relative to each other during the transmission process, so as to play the role of engaging or disconnecting power transmission, the active part of the clutch and Rigid links cannot be used between followers. Any form of automobile has a clutch device, but the form is different. The clutch in the field of automobiles and motorcycles is usually located in the flywheel housing between the engine and the gearbox. The clutch assembly is fixed on the rear plane of the flywheel with screws. The output shaft is the input shaft of the gearbox. When the car is running, the clutch is used to temporarily separate and gradually engage the engine and the gearbox according to needs, so ...

Problems solved by technology

[0004] In the above-mentioned patent documents, the oil injection pipe is directly connected to the bearing chamber through the oil injection hole. When the oil injection pipe is used to inject oil into the bearing chamber, it is not easy to control, which will lead to excessive grease injection and grease overflow, causing damage to the entire clutch.
