Problems solved by technology
[0002] With the development of science and technology, some precision machinery and high-end household appliances put forward stricter requirements on the vibration and noise of deep groove ball bearings. For example, air-conditioning appliances not only require low vibration and good sound quality of the bearings, but also require the bearings to have certain Life and noise life, the processing technology of ordinary bearings has been known and mastered by the technical personnel of the industry for a long time, but the outstanding problems are that the vibration value is large, the sound quality is poor, the vibration life and noise life cannot meet the requirements of the main engine
At present, the overall qualification rate of deep groove ball air-conditioning bearings produced in my country is not high in terms of performance and low noise quality level

Embodiment Construction
[0009] A deep groove ball air-conditioning bearing processing technology, including a heat treatment step, a shot blasting cleaning step, a plane outer circle processing step, and a groove grinding ultra-finishing step; the heat treatment includes quenching and tempering, and the quenching is heated to 770-840 ℃, keep warm for 30min~40min, put it in cooling oil for quenching, the oil temperature is <100℃, tempering is to heat to 155℃±5℃, keep warm for 3.5~4h, and cool naturally; the inner and outer rings of the bearing are quenched and tempered and then polished In the shot cleaning step, the steel shot whose diameter is smaller than the width of the dust-proof groove is sent to the high-speed rotating disc, and the centrifugal force is used to make the steel shot thrown at high speed hit the inner and outer ring surfaces of the bearing and the inside of the dust-proof groove to achieve smoothness. For the purpose of decoration and cleaning, shot blasting can generate compressi...

Abstract
The invention discloses a processing technology for deep groove ball air-conditioning bearings, which includes a heat treatment step, a shot blasting cleaning step, a plane outer circle processing step, and a groove grinding ultra-finishing step; the heat treatment includes quenching and tempering, and quenching is heating Heat to 770-840°C, keep warm for 30min-40min, place in cooling oil for quenching, oil temperature <100°C, tempering is to heat to 155°C±5°C, keep warm for 3.5-4h, and cool naturally; The value is large, the sound quality is poor, the vibration life and noise life are low, and the qualified ratio is low, which meets the requirements of the air conditioner main engine. This invention can effectively improve the qualified ratio of air conditioner bearings and reduce production costs.
