Description

Technical Field

[0001] The utility model relates to the field of engine bearings, in particular to an engine bearing which is easy to update and switch. Background Art

[0002] The bearing shell is the part where the sliding bearing and the shaft neck contact. It is in the shape of a semi-cylindrical shell and is very smooth. It is generally made of wear-resistant materials such as bronze and anti-friction alloy. In special cases, it can be made of wood, engineering plastics or rubber. There are two types of bearing shells: integral and split. Integral bearing shells are usually called shaft sleeves. Integral bearing shells are available in two types: with and without oil grooves. The bearing shell and the shaft neck are fitted with clearance and generally do not rotate with the shaft.

[0003] In the prior art, there is a heat-resistant engine bearing disclosed in publication number CN 217713354 U, which includes an upper tile and a lower tile. An oil filling hole is provided on the outside of the upper tile, and a lubrication mechanism is provided on the inside of the lower tile. The lubrication mechanism includes an oil inlet groove, and the lubrication mechanism also includes multiple oil distribution grooves arranged inside the lower tile. Upper shaft seats are respectively installed at both ends of the upper tile, and lower shaft seats are respectively installed at both ends of the lower tile. Threaded holes are commonly provided on the outside of the upper shaft seat and the lower shaft seat, and screws are connected to the internal threads of the threaded holes. Lubricating oil is added to the inside of the bearing through the oil filling hole. When the lubricating oil enters the interior of the upper tile, it will flow into the oil inlet grooves inside the upper tile and the lower tile. After the lubricating oil fully penetrates the oil inlet groove, it will continue to penetrate the multiple oil distribution grooves inside the upper tile and the lower tile, so that the lubricating oil will be evenly dispersed in the entire interior of the bearing without causing accumulation of oil stains.

[0004] However, the above patent has some shortcomings. In actual use, the upper bearing and the lower bearing of the above patent are connected by threaded holes and screws. However, the upper bearing and the lower bearing are connected and fixed by multiple screws.

[0023] Based on the above structure, by setting the fixing rod 18 and the clamping head 23 set at the top of the fixing rod 18, during installation, the fixing rod 18 and the clamping head 23 can be inserted into the through hole 16 by holding the holding rod 19, so that the clamping head 23 squeezes the two trapezoidal blocks 22. When the two trapezoidal blocks 22 are squeezed, the clamping head 23 continues to move forward through the contraction of the spring 21 and the sliding rod 20. When the clamping head 23 moves forward a certain distance, the clamping head 23 is clamped into the interior of the trapezoidal block 22, and the trapezoidal block 22 clamps the end with a larger diameter of the clamping head 23, thereby realizing the rapid installation between the upper bearing 1 and the lower bearing 2.

[0024] like Figure 3 and 4 As shown, the top sides of the two vertical plates 14 are installed with the same horizontal plate 15, and the top side of the horizontal plate 15 is provided with a through groove 26. The inner wall of the through groove 26 is slidably connected with two limit blocks 27, and the bottom sides of the two limit blocks 27 are respectively connected to the top sides of the corresponding two trapezoidal blocks 22. A cross bar 24 is installed on the inner wall of the through groove 26, and a avoidance hole is provided on one side of the two limit blocks 27. The two avoidance holes are respectively slidably connected with the surface of the cross bar 24, and rectangular rings 25 are installed on the top sides of the two limit blocks 27.

A heat dissipation net 6 is also slidably connected to the outside of the lower bearing 2, and the heat can be quickly conducted out through the honeycomb heat dissipation holes 9 set inside the heat dissipation net 6.

[0026] Working principle of this utility model:

[0027] When in use, by using the clamping head 23 set on the top of the fixing rod 18, during installation, the fixing rod 18 and the clamping head 23 can be inserted into the through hole 16 by holding the holding rod 19, so that the clamping head 23 squeezes the two trapezoidal blocks 22. When the two trapezoidal blocks 22 are squeezed, the clamping head 23 continues to move forward through the contraction of the spring 21 and the sliding rod 20.

When disassembling and replacing, it is only necessary to move the two rectangular blocks so that the two rectangular blocks drive the limit blocks 27 to slide on the cross bar 24, thereby driving the two trapezoidal blocks 22 to slide, so that the two trapezoidal blocks 22 are separated from the clamping head 23, and disassembly is realized. The operation is simple and convenient. The rectangular ring 25 can be moved by hand or with the help of tools, which saves the step of screwing the screws one by one.
