Description

Technical Field

[0001] The invention relates to the technical field of bearing grease injection equipment, in particular to automatic grease injection equipment for double-row tapered roller bearings. Background Art

[0002] The double-row tapered roller bearing in the axle box is an important component in vehicles in the rail transit field. During the bearing assembly process, it is required to inject a specified weight of grease into the three areas of the two-row inner components and the middle spacer ring to ensure the grease distribution in the bearing and thus improve the bearing performance. Storing grease in the middle spacer ring area can not only reduce the grease content in the inner component area to avoid the risk of grease leakage and excessive temperature rise in the operating area of ​​the bearing due to excessive grease, but also continuously provide grease to the bearing operating area to improve the lubrication condition. At present, manual greasing is commonly used for double-row tapered roller bearings in axle boxes. First, the product components are weighed separately, and then the grease gun is used to grease the two inner components and the middle spacer ring area (when greasing the middle spacer ring area, the outer ring, one inner component, and the middle spacer ring must be assembled before greasing to avoid grease overflow and dripping), and then they are weighed manually, and finally the grease injection amount and total grease injection amount of the two inner components and the middle spacer ring area are calculated. The entire greasing process is cumbersome and complicated, and it is difficult to ensure the cleanliness of the bearing interior due to multiple handling and weighing. At the same time, manual greasing is difficult to achieve large-scale stable production. At the same time, conventional automatic greasing equipment cannot grease the inside of double-row tapered roller bearings in different areas, and cannot meet the greasing requirements of rail transit axle box bearings. Summary of the invention

[0004] To achieve the above-mentioned purpose, the present invention provides an automatic greasing equipment for double-row tapered roller bearings, including an operating table, wherein the operating table is divided into a front working area, a middle area and a rear working area along its width direction, and the front working area and the rear working area are alternately divided into weighing areas and greasing areas along the length direction of the operating table, and the operating table is provided with a material shifting structure for separating external non-greased bearing components and combining greased bearing components, and a grease injection structure for greasing the bearing components is provided at a position corresponding to each greasing area on the operating table, and a flipping structure is provided at a position on one side of each weighing area corresponding to the rear working area on the operating table, and a detection piece for detecting the weight of the bearing component is provided at a position corresponding to each weighing area on the operating table, and a feeding structure for transferring the bearing component is provided at a position corresponding to the front working area and the rear working area on the operating table.
