Expanding device of full complement bearing rolling body filling port with ball filling notch

Abstract

The invention belongs to the technical field of bearings, and particularly relates to an expanding device of a full complement bearing rolling body filling port with a ball filling notch. The expanding device comprises an expanding inserting block and a positioning base, two expanding parts which extend downwards and can be inserted between a bearing outer ring and a bearing inner ring are arranged on the expanding inserting block, and a third ball filling notch allowing a rolling body to penetrate through is formed between the two expanding parts; and when the two expanding parts are inserted between the bearing outer ring and the bearing inner ring and located at the two sides of the rolling body filling port, the third ball filling notch is opposite to the rolling body filling port, the inner side caliber of the rolling body filling port can be expanded to the size of the rolling body by pressing the expanding inserting block downwards, and the rolling body can enter the rolling body filling port from the third ball filling notch and finally enters a roller path between the bearing outer ring and the bearing inner ring. By the adoption of the expanding filling manner, the filling port is complete, the rolling body does not need to be filled in an impacting manner, an extruding manner and the like, and the problems of collapse, ball surface scratching and the like are solved.

Description

【Technical field】 [0001] The invention belongs to the technical field of bearings, and in particular relates to a filling opening opening device for a rolling body of a full-complement bearing with a ball-filling notch. 【Background technique】 [0002] Compared with bearings with cages of the same specification, full complement rolling element bearings have higher load carrying capacity and are widely used. At present, full complement bearings, especially full complement ball bearings, usually open a ball filling gap on the diameter of the inner and outer ring ribs of the bearing, and fill a large number of balls into the bearing through the gap until it is filled, forming a full complement bearing. Limited by the bearing structure and the size of the ball filling gap, not all balls can be filled smoothly through the ball filling gap. A certain number of balls need to be filled by impact, extrusion, etc. It is inevitable that it will seriously affect the bearing quality and ...
