Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention;

referring to fig. 1 to 5, in the utility model, a hydraulic bearing oil storage structure comprises a base 1, a mounting groove 2 is formed in the top of the base 1, a machine core 3 is fixedly connected to the top of the base 1, a bearing upper stage 4 is fixedly connected to the inside of the machine core 3, a bearing lower stage 5 is fixedly connected to the bottom of the bearing upper stage 4, the outer diameter of the bearing lower stage 5 is smaller than that of the bearing upper stage 4, bearing holes 6 are formed in the bearing lower stage 5 and the bearing upper stage 4, the two bearing holes 6 are communicated, the bearing lower stage 5 is inserted into the mounting groove 2, and a shaft core 7 is inserted into the bearing holes 6.

According to the utility model, the installation is facilitated through the installation groove 2 on the top of the base 1, the machine core 3 is fixed on the top of the base 1, the upper bearing stage 4 and the lower bearing stage 5 are assembled, the shaft core 7 is inserted into the bearing hole 6, then the assembly of the upper bearing stage 4, the lower bearing stage 5 and the shaft core 7 is installed inside the machine core 3, an oil storage gap is formed between the lower bearing stage 5 and the installation groove 2, the space of the oil storage gap is enlarged due to the fact that the outer diameter of the lower bearing stage 5 is reduced, and therefore the device has the advantages of enlarging the oil storage space and prolonging the service life of a fan.

Please refer to fig. 1 and fig. 2, wherein: the outer side of the upper bearing level 4 is provided with assembling grooves 41 which are arranged at equal intervals, and the assembling grooves 41 are clamped with the inner part of the machine core 3.
