Abstract

A single-row cylindrical roller bearing holder comprises a holder seat and a holder cover which are fixedly connected. The holder seat comprises a plurality of support beams. A groove is formed in the inner side of each support beam. A ring of grooves are formed in an inner diameter of the holder seat. Due to the fact that the ring of the grooves is formed in the surface of inner diameter of the single-row cylindrical roller bearing holder seat, the grooves can play the role of storing dusts and oil, and ensuring lubrication of the bearing, and ensuring revolving and flexible functions of the bearing, and raw materials are saved. The single-row cylindrical roller bearing holder is a vehicle-made copper holder with grooves in the inner diameter, and capable of saving copper raw materials, lowering production cost, reducing friction, storing oil and lubricating, and being widely used in single-row cylindrical roller bearings such as NU, NJ, N, NUP, and NF and the like.

Description

technical field [0001] The invention belongs to the field of bearing cages, in particular to a cage for a single-row cylindrical roller bearing. Background technique [0002] The cage of the traditional single row cylindrical roller bearing is a car-made solid brass cage seat and cage cover, which are connected by rivets and play the role of separating and guiding the rollers. [0003] However, if the bearing load is too small during operation, sliding will occur between the rollers of the single row cylindrical roller bearing and the raceway, causing friction. Especially large single row cylindrical roller bearings with heavy rollers and cages. Invention content: [0004] The purpose of the present invention is to provide a single row cylindrical roller bearing cage, the cage has a ring of grooves on the inner diameter of the cage seat, reducing the sliding between the roller and the raceway, can store oil and dust, and save The raw material is copper, which reduces th...
