Embodiment Construction

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0035] see Figure 1 to Figure 3 , the present invention provides a technical solution:

[0036] A method for forging an outer ring or an inner ring of a double-row tapered bearing, comprising:

[0037] Step 1. Warm shear blanking: Use round steel with a suitable diameter according to the process requirements to determine the blanking length. When the long bar is heated to 800-850°C by an intermediate frequency induction heating furnace, it is sheared, and t...

Abstract

The invention discloses a forging method for an outer ring or an inner ring of a double-row conical bearing. The forming method mainly includes the following steps of: a heading and back-extrusion step, a punching and leveling step, a reaming step and a shaping step. The forging method disclosed by the invention adopts a carbon steel material; an initial blank is forged and forming-forged; different forging molds with same proportion are adopted; and the advantages of the process reduce the subsequent machining difficulty of products and save raw materials.

Description

technical field [0001] The invention relates to the technical field of forging, in particular to a forging method of an outer ring or an inner ring of a double-row tapered bearing. Background technique [0002] Tapered roller bearings are separable bearings, and the inner and outer rings of the bearing have tapered raceways. This type of bearing is divided into different structural types such as single row, double row and four row tapered roller bearings according to the number of rows of rollers installed. Single row tapered roller bearings can bear radial loads and axial loads in one direction. When the bearing bears radial load, an axial component force will be generated, so another bearing that can bear the axial force in the opposite direction is needed to balance it. The outer ring (or inner ring) of the double row tapered roller bearing is a whole. The small end faces of the two inner rings (or outer rings) are similar, and there is a spacer in the middle. The clea...
