Problems solved by technology

In general, the slewing bearing itself has installation holes, lubricating oil holes and sealing devices, etc., which can meet the different needs of various hosts working under various working conditions. It is precisely because of this structure that the host design structure It is more compact, easier to guide, more convenient to maintain, and is widely used in various large-scale slewing devices such as excavators, cranes, wind power, radar, medical equipment, and port machinery. Due to its particularity, the existing processing technology After processing, the precision of bearings often does not meet the requirements, and the yield is low. Relevant processing technology is required to ensure its accuracy and requirements.

Embodiment Construction

[0017] Specific embodiments of the present invention will be described in detail below.

[0018] The invention relates to a processing technology of a slewing disc bearing.

[0019] The processing technology of the slewing disc bearing described in this embodiment includes the following steps:

[0020] Step 1, blanking, blanking of forgings, and inspection of forging blanks;

[0021] Step 2, rough turning, complete the rough turning process according to the turning process drawings, the cutting speed is kept at 5 rpm, and the cutting amount is 10mm-12mm;

[0022] Step 3: Rough car aging. After the rough car work of the bearing parts, use three-point support and lay them flat. The aging time is not less than 48 hours;

[0023] Step 4, ferrule finish turning, the cutting speed should be kept at 6-8 rpm, and the cutting amount should be kept at 0.3-0.5mm;

[0024] Step 5: Forming and finishing turning. After the bearing parts arrive at the forming and finishing turning, fix an...

Abstract

The invention relates to the field of machining, in particular to a machining technology of a slewing bearing. The machining technology comprises the following steps of discharging material, a forgeable piece is discharged; rough turning, the rough turning is finished according to a turning technology drawing; rough turning aging; ferrule finish turning; forming finish turning; carrying out high-frequency quenching on the surface of a roller path; carrying out the high-frequency quenching on the surface of the roller path; tempering machining; grinding and machining; scribing; drilling; and assembling, a play gap is manufactured. The machining technology of the slewing bearing has the beneficial effects that the machining quality and machining precision of a workpiece are guaranteed, the production efficiency is improved, and the production cost of the machining technology of the slewing bearing is reduced.

Description

technical field [0001] The invention relates to the field of mechanical processing, and more specifically relates to a processing technology of a slewing disc bearing. Background technique [0002] Slewing disc bearings, also known as slewing bearings, are mainly special bearings that can simultaneously withstand large axial loads, radial loads, and overturning moments and other comprehensive loads. In one large bearing with special structure. In general, the slewing bearing itself has installation holes, lubricating oil holes and sealing devices, etc., which can meet the different needs of various hosts working under various working conditions. It is precisely because of this structure that the host design structure It is more compact, easier to guide, more convenient to maintain, and is widely used in various large-scale slewing devices such as excavators, cranes, wind power, radar, medical equipment, and port machinery. Due to its particularity, the existing processing t...
