Embodiment Construction

[0032] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail through the following examples. However, it should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0033] A processing method of a toothless bearing and the bearing, the processing steps of the outer ring are as follows:

[0034] (1) Rough turning: Clamp the forging blank, correct the inner circle runout to 0-1.6mm, and the outer circle runout to 0-0.5mm, carry out rough turning processing according to the turning process drawings, and control the diameter error of the outer circle and the inner circle. greater than 1 mm, and the single-turn height error is not greater than 0.8 mm; the material grade of the forging blank used in the present invention is 50Mn.

[0035] (2) Semi-finishing tu...

Abstract

The invention discloses a machining method of a non-tooth bearing and the bearing. The machining method comprises the following steps of rough turning, semi-finish turning, thermal treatment, finish turning, marking, drilling, oil hole forming, assembling and storing into a warehouse. According to the machining method of the non-tooth outer ring bearing, an induction heat treatment technology is adopted, an electromagnetic coil is powered on for heating, and compared with a traditional heat treatment technique, the method has the advantages that the process is simple, the heat treatment cost is low, and the quality of the manufactured bearing part is good. According to the machining method of the non-tooth bearing and the bearing, an oil hole is formed in a punching mode, the formed oil hole has the characteristics that the number of burrs is small and the roundness is good compared with an oil hole formed in a traditional drilling mode, and efficiency is also improved by 3-4 times. By application of the machining method of the non-tooth bearing and the bearing, the production cost can be effectively reduced, and benefits are improved.

Description

technical field [0001] The invention relates to a mechanical processing technology, in particular to a processing method of a toothless bearing and the bearing. Background technique [0002] Bearing is a general-purpose part widely used in machinery manufacturing industry. It is characterized by high speed, large bearing force, small friction force, high precision, and can bear radial and axial loads. In the manufacturing process of bearings, in order to make the bearings have higher hardness, sufficient wear resistance and longer service life, it is necessary to heat treat the bearings. Traditional bearing processing technology is difficult to meet the needs of bearings in terms of hardness, toughness, bearing capacity and service life. Contents of the invention [0003] Aiming at the above-mentioned problems in the prior art, the present invention provides a processing method for a toothless bearing, which can effectively reduce the production cost of the toothless out...
