Detailed Description
The invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic drawings and illustrate, by way of illustration only, the basic structure of the invention, and which therefore show only the constituents relevant to the invention. It should be noted that the terms "front," "back," "left," "right," "upper" and "lower" used in the following description refer to directions in the drawings, and the terms "inner" and "outer" refer to directions toward and away from, respectively, the geometric center of a particular component.
As shown in fig. 1-3, a fan bearing box for reducing oil spillage comprises a bearing box body 1 and side covers 2 arranged on two sides of the bearing box body 1, and the bearing box body and the side covers are fastened through bolts; the end face of the bearing box body 1 and the side cover 2 are both provided with central holes through which a transmission main shaft of a fan can pass.
An oil pool cavity 11 and a bearing cavity 12 are arranged in the bearing box body 1; wherein, two bearing cavities 12 are arranged on two sides of the oil pool cavity 11.
Two grooves 22 are arranged on the inner wall of a central hole 21 arranged on the side cover 2 along the axial direction of the central hole 21, each groove 22 surrounds the circumference of the inner wall of the central hole 21 for a circle, and an oil absorption material (such as polyacrylate oil absorption expansion rubber) is arranged in each groove 21; lubricating oil passes through recess 21 when leaking along fan transmission main shaft to the outside, and the oil absorption expanded rubber in recess 21 can be siphoned away lubricating oil to the leakage of lubricating oil along fan transmission main shaft to the outside has been reduced.
Three rings of annular protrusions 23 are arranged on the inner end surface (namely the surface attached to the end surface of the bearing box body 1) of the side cover 2, and the three rings of annular protrusions 23 are arranged concentrically; the annular protrusion 23 is made of oil-absorbing expansion rubber (such as polyacrylate oil-absorbing expansion rubber); the end surface of the bearing box body 1 is provided with a three-ring annular groove 13 corresponding to the annular protrusion 23 (corresponding to the size, the position and the like); the three-turn annular protrusion 23 can be just inserted into the corresponding three-turn annular groove 13. The arrangement can increase the path of lubricating oil leaking from the gap between the bearing box body 1 and the side cover 2 (if the lubricating oil needs to leak, the lubricating oil needs to do a plurality of times of tortuous movements), thereby increasing the difficulty of the lubricating oil leaking from the gap between the bearing box body 1 and the side cover 2 and reducing the leakage of the lubricating oil; meanwhile, the annular protrusion 23 is made of oil absorption expansion rubber (such as polyacrylate oil absorption expansion rubber), so that not only can lubricating oil flowing into a gap between the bearing box body 1 and the side cover 2 be absorbed, but also the oil absorption expansion rubber expands after absorbing oil, thereby increasing the sealing performance of the bearing box body 1 and the side cover 2, and achieving two purposes at one stroke.
The inner side of the side cover 2 is provided with an annular cavity 24 corresponding to the position and the size of the bearing cavity 12; 4 baffle plates 241 are arranged in the annular cavity 12 along the radial direction; the baffle piece 241 is rectangular; which is connected to both the side and the bottom of the annular chamber 12; after the baffle 241 is arranged, the splashed lubricating oil can be blocked by the baffle 241 and slides down along the baffle when the fan transmission main shaft rotates, so that the splashing of the lubricating oil can be effectively reduced.
The base 3 is arranged at the bottom of the bearing box body 1, and the annular spring shock absorption piece 31 is arranged at the bottom of each base 3, so that the vibration of the whole device in operation is reduced.
In addition, the bearing box body 1 is of an integrated structure which is integrated up and down, and compared with the structure that the existing fan bearing box adopts the upper cover and the lower cover, the quality problem caused by vibration and looseness of the fixing bolts in use and the oil leakage phenomenon at the joint surface of the upper cover and the lower cover are reduced.
