[0006] The beneficial effects of the present invention are as follows: a frame body is composed of a first ring body, a second ring body and a plurality of beam bodies, wherein pockets formed between adjacent beam bodies are used to accommodate rollers; on at least one ring body, each pocket position corresponds to at least one oil storage hole, and oil storage ring boxes are provided at positions corresponding to the oil storage holes in the circumferential direction of the ring body, and these oil storage ring boxes can be detachably connected to the ring body along the circumference of the ring body, and a sealing layer is provided between the oil storage ring box and the ring body to ensure the sealing of the lubricant; by arranging the oil storage ring box inside the retaining frame, the lubricant can be redistributed from the oil storage ring box to the surface of the rolling element when the lubricant supply is insufficient, thereby effectively suppressing the oil shortage phenomenon, improving lubrication supply, and increasing service life. The detachable oil storage ring box design makes maintenance and lubricant replacement easier, thereby reducing maintenance costs.

[0007] Furthermore, a plurality of oil storage holes are evenly distributed on the first ring body at positions corresponding to the pockets, and the rollers in the pockets can contact the oil storage holes.

[0008] By setting a plurality of oil storage holes and correspondingly setting the rollers in the pocket holes, the number of oil storage holes is large, the oil storage capacity is large, the oil supply is more sufficient, and the roller surface is not prone to lack of grease.

[0009] Furthermore, the oil storage holes are square oil storage holes, and the oil storage holes on the first ring body are arranged in double rows corresponding to each pocket.

[0010] The square oil storage hole can make the shape of the oil storage hole more regular and the manufacturing is more convenient. The edge of the square oil storage hole can appropriately scrape off excess grease on the roller surface, and the grease is not easy to overflow.

[0011] Furthermore, the sealing layer is a sealing gasket for preventing lubricating oil from leaking from the first ring body. The oil storage ring box is sealed after being connected to the first ring body, and the oil storage hole is connected to the opening of the oil storage ring box.

[0012] The use of a sealing gasket can improve the sealing performance between the oil storage ring box and the first ring body. The oil storage hole is connected to the opening of the oil storage ring box, making oil discharge more convenient. In this solution, the oil storage ring box can only be sealed with the first ring body after being inserted into the first ring body by technicians in this field.

[0013] Furthermore, the oil storage ring box has an arc-shaped inner wall, and the cross section of the oil storage ring box is arc-shaped.

[0014] The oil storage ring box with an arc-shaped inner wall can prevent impurities in the grease from being retained in the oil storage ring box, avoid impurities from accumulating, and is also easy to clean. BRIEF DESCRIPTION OF THE DRAWINGS
