Abstract

The invention discloses a bearing lubrication mechanism of an oil-free scroll compressor. The bearing lubrication mechanism comprises a housing, a first bearing, a second bearing, an outer bearing pedestal, a fixed scroll, a threaded hole, an unthreaded hole, a crankshaft and a bearing pedestal; the outer bearing pedestal, the housing and the fixed scroll form a sealed cavity; the first bearing and the second bearing are located in the sealed cavity; the crankshaft is made into a hollow shaft; the hollow shaft consists of the threaded hole and the unthreaded hole sequentially; the bearing pedestal and the crankshaft form a cavity; and the threaded hole, the unthreaded hole and the cavity form a channel communicating to lubrication parts of the first bearing and the second bearing. The bearing lubrication mechanism further comprises a lubrication oil filling mechanism which is connected with the threaded hole. Since no disassembling action requires in a maintenance operation process, the workload of maintenance staff is relieved, the operation experience requirement on the maintenance staff is reduced, the quality of rotating components is reduced, and the overall efficiency of the oil-free scroll compressor is improved to a certain extent.

Description

technical field [0001] The invention relates to an oil-free scroll compressor bearing lubricating mechanism, in particular to an oil injection structure of the lubricating mechanism. Background technique [0002] After the oil-free scroll compressor has been used for a period of time, lubricating grease must be injected into the anti-rotation bearing for periodic maintenance. However, the oil injection method in the prior art needs to dismantle the fixed scroll part of the body before the oil injection can be carried out for the oil injection nozzle of the bearing. [0003] Such as figure 1 As shown, it is a kind of bearing lubricating oil injection structure that is widely used in oil-free scroll compressors in the prior art. In the figure, it is necessary to first remove the fixed scroll and the wind guide cover on the left half (removed in the figure), and use the oil injection tool 39 to inject the lubricating grease through the oil injection nozzle 35 and the oil inle...
