Description

Technical Field

[0001] The utility model relates to the technical field of sliding bearings, and particularly relates to a double-row sliding bearing. Background Technique

[0002] A sliding bearing is a bearing that works under sliding friction. It usually consists of a bearing housing, a bearing bush, a lubrication system, etc. Its working principle is to rely on the lubricating oil film formed between the journal and the bearing bush to bear the load and reduce friction and wear.

[0003] According to the Chinese patent with the publication number "CN220337263U", a sliding bearing that is easy to lubricate is disclosed. It includes a shaft, a shaft sleeve, and a rotating part. The shaft has a structure with a smooth rod bolt. The shaft sleeve is sleeved on the smooth rod part of the bolt, and the shaft sleeve is integrally sleeved in the inner hole of the rotating part. A nut is screwed onto the bolt to fixedly connect the shaft, the shaft sleeve, and the rotating part together. The shaft has a structure with a smooth rod bolt, and a blind hole is provided in the smooth rod part of the bolt. The outlet of the blind hole is on the end face of the fixing nut of the bolt itself. A grease nipple is provided at the outlet of the blind hole, and the grease nipple does not protrude beyond the nut end face of the bolt. A radial hole is provided in the smooth rod part of the bolt to communicate with the bolt blind hole, and a spiral oil groove is provided on the smooth rod surface of the bolt. The spiral oil groove communicates with the radial hole through the radial hole. The copper sleeve is a composite copper sleeve, which is divided into two structures: the surface of the composite copper sleeve has no holes and has multiple small holes. Advantages: The grease nipple is convenient for refueling and not easily damaged, and the service life of the parts is greatly increased. When the above-mentioned bearing is in use, a collection and filtration structure is not provided. After the lubricating oil is used for a period of time, it often needs to be replaced due to reasons such as impurity mixing and performance degradation. This not only increases the use cost, but also causes waste of resources and environmental pollution. Therefore, a double-row sliding bearing is proposed to solve the above-mentioned problems.
