specific Embodiment approach 1

[0019] Specific implementation mode one: combine figure 1 and image 3 Describe this embodiment, an anti-light-load slipping square pocket cage of this embodiment, which includes an outer ring 1, an inner ring 2, cylindrical rollers 3 and a cage 4, the outer ring 1 and the inner ring 2 There is a cage 4 between them, and the cage 4 is an annular cage, and a plurality of square pockets 4-1 are evenly opened on the circumference of the annular cage, and the cylindrical roller 3 is installed in the square pocket 4 of the cage 4 -1, a circular pocket 4-2 is opened between two adjacent square pockets 4-1 of the cage 4, and the number of square pockets 4-1 of the cage 4 is equal to the circle of the cage 4. The quantity of shape pocket 4-2 is equal.

specific Embodiment approach 2

[0020] Specific implementation mode two: combination figure 1 and figure 2 Describe this embodiment, the square pockets 4 - 1 of this embodiment are evenly and symmetrically distributed on the cage 4 . In this way, the square pocket 4-1 is used for positioning and isolating the cylindrical rollers 3 to prevent the inclination of the cylindrical rollers 3 or friction between the cylindrical rollers 3, effectively preventing the increase of the rotational torque. Other compositions and connections are the same as in the first embodiment.

specific Embodiment approach 3

[0021] Specific implementation mode three: combination figure 1 and figure 2 To describe this embodiment, the circular pockets 4 - 2 of this embodiment are evenly and symmetrically distributed on the cage 4 . In this way, the circular pockets 4-2 are evenly and symmetrically distributed on the cage 4, which is conducive to maintaining the dynamic balance of the cylindrical roller bearing and improving the load-carrying capacity of a single roller. Other compositions and connections are the same as those in Embodiment 1 or Embodiment 2.

Abstract

The invention discloses an anti-light-loading-skidding square and round pocket holder, and relates to the technical field of cylindrical roller bearing. The problems that an existing cylindrical roller bearing is prone to slipping under the working condition of high speed and light load, the failure of a bearing is caused, and the life and reliability of the bearing are seriously affected are solved. A holder is arranged between an outer ring and an inner ring, and the holder is in a circular ring shape. A plurality of square pockets are evenly formed on the circumference of the circular-ring-shaped holder. Cylindrical rollers are arranged in the square pockets of the holder. A round pocket is formed between the two adjacent square pockets of the holder. The number of the square pockets inthe holder is equal to the number of round pockets in the holder. The anti-light-loading-skidding square and round pocket holder is used to improve the bearing capacity of a single roller of the cylindrical roller bearing, reduce the weight of the holder, and solve the problem of bearing slippage.

Description

technical field [0001] The invention relates to the technical field of cylindrical roller bearings, in particular to an anti-light-load slipping square-circle pocket cage. Background technique [0002] Slipping accounts for a certain proportion of engine main shaft bearing failures, especially under high-speed and light-load conditions. After slipping, the friction inside the bearing causes rapid heating, which reduces the viscosity of the lubricating oil and reduces the thickness of the oil film, eventually causing "slipping" and causing the bearing to fail. Slipping has certain incentives for bearing cracks, peeling, abrasions, wear, plastic deformation, gluing and cage damage, and has a serious impact on the life and reliability of bearings. In addition, the sliding friction during the sliding process of the rolling bearing is one of the excitation sources of the vibration and noise of the rolling bearing, which induces the abnormal vibration and noise of the rolling bea...
