They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0023] In addition, the terms "first," "second," etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. In the description of this utility model, "plurality" means more than two, unless otherwise specifically defined.

[0024] like Figure 1-Figure 3 As shown, the utility model provides a fixing structure for installing a generator thrust bearing oil cooler, which is arranged between an oil cooler oil retaining ring 10 and an oil cooler frame 20 , and a connecting hole is opened on the oil cooler oil retaining ring 10 .

[0025] It should be noted that the generator thrust bearing oil cooler is annular. To achieve effective fixation, multiple fixing structures are spaced apart inside the oil cooler frame 20 to tighten the oil baffle at multiple points. The above is all prior art, and the specific structure will not be repeated here. The utility model includes a fixing base 30, a first screw 40, an upper nut 50, and a lower nut 60.

[0026] The fixing seat 30 is arranged in the transverse direction and fixedly mounted on the oil cooler frame 20 by welding.

[0027] The first screw rod 40 passes through the fixing seat 30 in the longitudinal direction.

[0028] The upper nut 50 and the lower nut 60 are both sleeved on the first screw rod 40 and are located above and below the fixing base 30 respectively.

[0029] The specific usage process of the present utility model is as follows: first, after the staff passes the first screw 40 through the fixing seat 30 in the longitudinal direction, the upper nut 50 and the lower nut 60 are sleeved and connected to the first screw 40, and the first screw 40 is adjusted by the upper nut 50 and the lower nut 60. The upper nut 50 and the lower nut 60 can both be against the fixing seat 30 to lock the first screw 40, and the lower end of the first screw 40 is against the top of the oil cooler oil baffle, thereby pressing the oil cooler oil baffle to achieve a fixing effect. There is no need to re-drill the connection hole on the oil cooler oil baffle, which effectively reduces the maintenance time and improves the maintenance efficiency. The oil cooler oil baffle ring 10 can be quickly fixed to the oil cooler frame 20.

[0030] In one embodiment, a pressure pad 70 is further included. A rotating column 71 is provided on the top of the pressure pad 70. A first threaded hole is opened on the top of the rotating column 71, and the first threaded hole is matched with the first screw rod 40.

[0031] After the first screw rod 40 passes through the fixing seat 30 , the upper nut 50 and the lower nut 60 are connected to the first screw rod 40 , and then the rotating column 71 on the pressure pad 70 is threadedly connected to the bottom of the second screw rod 85 .

[0032] The design of the pressure pad 70 can increase the contact area between the present invention and the oil baffle of the oil cooler, thereby improving reliability. The pressure pad 70 is detachably connected to the first screw rod 40 via a thread, thereby avoiding the problem that the first screw rod 40 cannot be removed from the fixing base 30.

[0033] In one embodiment, the rotating post 71 is rotatably connected to the pressure pad 70 .

[0034] In one embodiment, a second threaded hole 72 is formed on the outer circumference of the pressure pad 70 .

[0035] The oil cooler oil deflector 10 is provided with a stabilizing assembly 80, which includes a fixed plate 81, a threaded column 82, a rotating plate 83, a fixed block 84, and a second screw 85. The fixed plate 81 is provided on the oil cooler oil deflector 10. The threaded column 82 is fixedly mounted on the bottom of the fixed plate 81 and engages with the first threaded hole. The rotating plate 83 is provided on the fixed plate 81 and is rotatably connected to the fixed plate 81. The fixed block 84 is fixedly mounted on the rotating plate 83. The second screw 85 passes through the fixed block 84 in the horizontal direction and is threadedly connected to the fixed block 84. The second screw 85 engages with the second threaded hole 72.

[0036] While the upper nut 50 and lower nut 60 are tightening the first screw 40, the operator can adjust the position of the pressure pad 70 so that the second threaded hole 72 is aligned with the second screw 85. After the bite pad is pressed against the oil cooler baffle, the operator can rotate the rotating plate 83 and the second screw 85 until the second screw 85 engages with the second threaded hole 72. This further secures the position of the first screw 40 and the pressure pad 70, preventing any wobble and improving the stability of the present invention.

[0037] In one embodiment, a handle 86 is fixedly mounted on the outer end of the second screw rod 85 to facilitate a worker to control the rotation of the second screw rod 85 .

[0038] In one embodiment, a rubber pad is fixedly mounted on the bottom of the pressure pad 70 to increase the friction between the bite block pad and the oil cooler oil deflector 10 .

[0039] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.
