Problems solved by technology

[0002] The processing quality of the large rib oil groove in the inner ring of the tapered roller bearing not only affects the grinding process of the ring, but also affects the quality of the finished bearing
The traditional processing method of the large rib oil groove in the inner ring of the tapered roller bearing is mainly: use an ordinary lathe, manually sharpen the oil groove knife for cutting, the tool wears quickly, the product has low dimensional accuracy and poor quality; and it is affected by the material of the tool , the ferrule is turned before it is quenched, and it needs to be ground after turning, so the production efficiency is low

Embodiment 1

[0013] A kind of turning process of tapered roller bearing ring, including outer ring turning process and inner ring turning process, said inner ring turning process includes the turning process of inner ring large rib oil groove, when tapered roller When the width of the inner ring of the bearing is less than or equal to 30mm, the turning process of the large rib oil groove of the inner ring is specifically: hard turning the large rib oil groove of the inner ring after quenching, and using the inner clip type three-jaw chuck to The inner ring is clamped on the CNC lathe, and the oil groove of the large rib of the inner ring is cut with a 40°V-shaped blade. When cutting, the spindle speed of the CNC lathe is 450-470rad / min, and the feed rate is 0.03-0.04mm / r.

[0014] The internal clamping three-jaw chuck is an internal clamping floating three-jaw chuck with a self-repairing function, which can realize slight floating in the axial and radial directions, even if the shape erro...

Embodiment 2

[0017] A kind of turning process of tapered roller bearing ring, including outer ring turning process and inner ring turning process, said inner ring turning process includes the turning process of inner ring large rib oil groove, when tapered roller When the width of the inner ring of the bearing is greater than 30mm, the turning process of the large rib oil groove of the inner ring is specifically: Carry out hard turning on the large rib oil groove of the inner ring after quenching, and use the inner clip type three-jaw chuck to turn the inner ring The ring is clamped on the CNC lathe, and the oil groove of the large rib of the inner ring is cut with a 40°V-shaped blade. When cutting, the spindle speed of the CNC lathe is 470-480rad / min, and the feed rate is 0.04-0.05mm / r .

[0018] The internal clamping three-jaw chuck is an internal clamping floating three-jaw chuck with a self-repairing function, which can realize slight floating in the axial and radial directions, even i...

Abstract

The invention discloses a turning process of a tapered roller bearing ring. The turning process comprises an outer ring turning process and an inner ring turning process; the inner ring turning process comprises a turning process of an inner ring large flange oil groove; and the turning process of the inner ring large flange oil groove is specifically as follows: the quenched inner ring large flange oil groove is hardly turned; an inner clamping type three-jaw chuck is adopted to clamp an inner ring on a numerical control lathe; a 40-degree V-shaped blade is used for cutting the inner ring large flange oil groove; and in cutting, the rotating speed of a main shaft of the numerical control lathe is 450-480 rad / min, and the feed rate is 0.03-0.05 mm / r. Through the mode, the turning process of the tapered roller bearing inner ring large flange oil groove is simplified; and meanwhile, the cutter wear can be reduced, the size precision and the production efficiency are improved, and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of bearing manufacture, in particular to a turning process for tapered roller bearing rings. Background technique [0002] The processing quality of the large rib oil groove in the inner ring of the tapered roller bearing not only affects the grinding process of the ring, but also affects the quality of the finished bearing. The traditional processing method of the large rib oil groove in the inner ring of the tapered roller bearing is mainly: use an ordinary lathe, manually sharpen the oil groove knife for cutting, the tool wears quickly, the product has low dimensional accuracy and poor quality; and it is affected by the material of the tool , The ferrule is turned before it is quenched, and it needs to be ground after turning, so the production efficiency is low. Contents of the invention [0003] The technical problem mainly solved by the present invention is: aiming at the deficiencies of the prior a...
