Retainer for tapered roller bearing

The utility model discloses a retainer for a tapered roller bearing, which belongs to the technical field of bearing retainers and comprises a tapered frame body, a collecting groove is arranged in the tapered frame body, a plurality of storage grooves are arranged in the collecting groove, a collecting groove is arranged in the collecting groove, and a control groove is arranged on one side of the tapered frame body. According to the retainer for the tapered roller bearing, a flow guide groove is formed, then a limiting block is pulled outwards to disassemble a stop block, then external adsorption cotton is stuffed into a control groove, in this way, the stop block is disassembled by kneading the limiting block, redundant lubricating oil is adsorbed through the external adsorption cotton, and the lubricating oil is separated from the stop block; the roller bearing effectively avoids excessive lubricating oil between the roller and the conical frame body, reduces accumulation of the lubricating oil, ensures n
