Oil injection mechanism of compression bearing

Abstract

The invention relates to an oil injection mechanism of a compression bearing. The oil injection mechanism comprises an elastic ring, a bearing and an oil injection ring assembly fixed to a cartridge receiver, wherein a bayonet is arranged at a ring opening of the elastic ring, the bearing is arranged in the elastic ring in a locked manner, the oil injection ring assembly is arranged at the other end of the elastic ring for fixing the bearing, and the oil injection ring assembly is fixed to the cartridge receiver through a plurality of nuts; the oil injection ring assembly is of a hollow annular structure, an oil pipe is arranged in the oil injection ring assembly, the oil injection ring assembly is provided with an oil inlet and an oil outlet, and an oil injection nozzle is arranged on thesurface, facing the bearing, of an oilway of the oil injection ring assembly. A limiting protrusion is arranged in a contact part of the oil injection ring assembly and the bearing, the limiting protrusion on the oil injection ring assembly presses an outer ring of the bearing, and the limiting protrusion is a protruding round ring. The oil injection mechanism of the compression bearing integrates a bearing fixing structure and the nozzle, achieves bearing fixing and lubricating functions on the premise of saving designing and mounting spaces, and is convenient to assemble and high in reliability.

Description

technical field [0001] The invention belongs to the technical field of mechanical structures, and relates to an oil injection mechanism, in particular to an oil injection structure for a compression bearing. Background technique [0002] When the fulcrum of the main shaft bearing is fixed and lubricated in the design of the engine, the nut structure is often used to fix the bearing, and the nozzle structure needs to be designed to lubricate the main shaft bearing. In the case of limited design space, it is difficult to design the fixing and lubricating structure of the bearing separately. Moreover, the engine main shaft designed in this way is cumbersome when disassembling and has many parts, resulting in reduced reliability. Contents of the invention [0003] In order to solve the above problems, the present invention provides a compression bearing oil injection structure, which integrates the bearing fixing structure and the nozzle, and realizes the bearing fixing and lu...

Problems solved by technology

[0002] When the fulcrum of the main shaft bearing is fixed and lubricated in the design of the engine, the nut structure is often used to fix the bearing, and the nozzle structure needs to be designed to lubricate the main shaft bearing. In the case of limited design space, the fixing and lubricating structure of the bearing is designed separately, which makes the design difficult

Moreover, the engine main shaft designed in this way is more troublesome in disassembly and assembly, and there are many parts, resulting in reduced reliability
