Description

Technical Field

[0001] The utility model relates to the field of bearing processing equipment, in particular to pretreatment equipment for bearing assembly. Background Art

[0002] Bearing installation generally adopts two methods: press-in and heat-fit. Heat-fit is an installation method that heats the bearing or bearing seat and uses thermal expansion to transform a tight fit into a loose fit. Oil bath heating is before heat-fitting. The bearing or the ring of the separable bearing is placed in the oil tank and heated evenly to 80-100°C. Then it is taken out of the oil and installed on the shaft as soon as possible. When heating the bearing with an oil tank, there should be a grid at a certain distance from the bottom of the box, or the bearing should be hung with a hook. The bearing cannot be placed on the bottom of the box to prevent impurities from entering the bearing or uneven heating. There must be a thermometer in the oil tank, and the oil temperature must be strictly controlled not to exceed 100°C to prevent tempering effect and reduce the hardness of the ring. However, the existing pretreatment equipment for bearing assembly will have residual coolant or impurities on the surface during processing, and there is air inside the coolant or impurities. Therefore, when the large bearing is heated, the air must be discharged, and bubbles will be formed in the oil. The air in the bubbles will burst due to the high temperature, causing it to float on the surface of the oil. The bubbles will explode the oil, posing a safety problem. Therefore, it does not meet the existing needs. In this regard, we propose a pretreatment equipment for bearing assembly. Utility Model Content
