Description

Technical Field

[0001] This utility model relates to the field of bearing technology, specifically to a bearing with anti-detachment function. Background Technology

[0002] Bearing shells are crucial engine components, located at the contact point between the sliding bearing and the journal. Shaped like a tile-like semi-cylindrical surface, they are very smooth and typically made of metal. They have oil injection holes on their walls and annular oil grooves on their inner surfaces. These grooves provide lubrication, and a suitable amount of lubricating oil is added to their inner surfaces. Poor lubrication can cause the bearing to generate excessive heat during high-speed rotation within the bearing shell. Direct friction and high temperatures can burn out the bearing shell. Other factors that can cause bearing burnout include excessive load, excessive temperature, impurities in the lubricating oil, or abnormal viscosity. Once the bearing shell burns out, the sliding bearing is damaged.

[0003] The existing technology has the following problems:

[0004] 1. Existing bearing bushes have a simple installation structure but poor installation stability, making them prone to falling off during operation and causing equipment damage. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bearing bush with anti-detachment function, comprising a bearing body arranged in a semi-circular shape, a connecting groove at one end of the bearing body, a retaining strip at the other end of the bearing body, a fixing ring at the top of the bearing body, a retaining groove at the bottom of the bearing body, a retaining block at the bottom of the fixing ring, an oil injection hole and an oil outlet hole on the bearing body, a bolt groove at the top of the fixing ring, a second threaded hole at the top of the retaining groove, and a fixing bolt inside the bolt groove.

[0007] As a preferred embodiment of this utility model, the connecting groove, the card strip, the card slot, and the card block are all trapezoidal in shape. The connecting groove and the card strip are compatible. The card slot and the card block are provided in multiple sets and are equidistantly distributed.

[0008] As a preferred embodiment of this utility model, the oil injection hole is located on the outer side near the top of the tile body, and multiple sets of oil outlet holes are located on the inner side of the tile body. An oil delivery groove is provided inside the tile body.

[0009] In a preferred embodiment of this utility model, the oil injection hole and the oil outlet hole are respectively connected to the oil delivery tank, and the oil injection hole and the oil outlet hole are respectively inclined downwards.

[0010] As a preferred embodiment of this utility model, the bolt groove is hexagonal, and the locking block has a first threaded hole at the position corresponding to the bolt groove. The threaded end of the fixing bolt is adapted to the first threaded hole and the second threaded hole respectively.

[0011] Compared with the prior art, this utility model provides a bearing bush with anti-detachment function, which has the following beneficial effects:

[0012] 1. This type of bearing bush with anti-detachment function connects the ends of the two bearing bodies by inserting the connecting groove into the inside of the locking strip during the merging process. When the merging is completed, the locking groove is also inserted into the inside of the locking block, and the threaded end of the fixing bolt is turned into the inside of the first threaded hole and the second threaded hole to fix the two bearing bodies together, thereby locking the two bearing bodies together and preventing them from detaching during use.

[0013] 2. This type of bearing bush with anti-detachment function is equipped with an oil injection hole, an oil supply groove, and an oil outlet hole. Before use, lubricating oil is added into the oil supply groove through the oil injection hole and the oil injection hole is sealed. The lubricating oil inside the oil supply groove flows out through multiple sets of oil outlet holes, which facilitates the flow of lubricating oil to the whole body of the bearing bush.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 In this embodiment: a bearing bush with anti-detachment function includes a bearing body 1, which is semi-circular in shape. One end of the bearing body 1 is provided with a connecting groove 2, and the other end of the bearing body 1 is provided with a retaining strip 3 to increase stability. The top of the bearing body 1 is provided with a fixing ring 4 to increase stability. The bottom end of the bearing body 1 is provided with a retaining groove 5, and the bottom end of the fixing ring 4 is provided with a retaining block 6. The bearing body 1 is provided with an oil injection hole 7 and an oil outlet hole 9 to facilitate the injection of lubricating oil into the bearing body 1. The top of the fixing ring 4 is provided with a bolt groove 10, the top of the retaining groove 5 is provided with a second threaded hole 12, and the bolt groove 10 is provided with a fixing bolt 13 to increase stability.

[0021] In this embodiment, the connecting groove 2, the locking strip 3, the locking slot 5, and the locking block 6 are all trapezoidal. The connecting groove 2 and the locking strip 3 are compatible. The locking slot 5 and the locking block 6 are provided in multiple sets and are equidistantly distributed. During installation, two tile bodies 1 of the same size are symmetrically merged into a circle. During merging, the connecting groove 2 is inserted into the inside of the locking strip 3 to connect the ends of the two tile bodies 1. When the merging is completed, the locking slot 5 is also inserted into the inside of the locking block 6, thereby locking the two tile bodies 1 together and preventing them from separating during use. The oil injection hole 7 is opened on the outer side near the top of the tile body 1, and multiple sets of oil outlet holes 9 are opened on the inner side of the tile body 1. An oil supply groove 8 is opened inside the tile body 1. The oil injection hole 7 and the oil outlet hole 9 are respectively connected to the oil supply groove 8. The grooves 8 are connected, and the oil injection hole 7 and oil outlet hole 9 are respectively inclined downwards. By setting the oil injection hole 7, the oil delivery groove 8 and the oil outlet hole 9, lubricating oil is added into the interior of the oil delivery groove 8 through the oil injection hole 7 before use, and the oil injection hole 7 is sealed. The lubricating oil inside the oil delivery groove 8 flows out through multiple sets of oil outlet holes 9, which facilitates the flow of lubricating oil to the whole body of the tile 1. The bolt groove 10 is hexagonal, and the locking block 6 has a first threaded hole 11 corresponding to the position of the bolt groove 10. The threaded end of the fixing bolt 13 is adapted to the first threaded hole 11 and the second threaded hole 12 respectively. By rotating the fixing bolt 13, the threaded end of the fixing bolt 13 is turned into the interior of the first threaded hole 11 and the second threaded hole 12, which fixes the two tile bodies 1 together and prevents them from separating during use.

[0022] The working principle and usage process of this utility model are as follows: The operator merges two identical tile bodies 1 into a circle in a symmetrical direction. During the merging process, the connecting groove 2 is inserted into the inside of the locking strip 3 to connect the ends of the two tile bodies 1. When the merging is completed, the locking groove 5 is also inserted into the inside of the locking block 6 to lock the two tile bodies 1 together. Then, the fixing bolt 13 is rotated to turn the threaded end of the fixing bolt 13 into the inside of the first threaded hole 11 and the second threaded hole 12 to fix the two tile bodies 1 together and prevent them from separating during use. At the same time, lubricating oil is added into the inside of the oil supply groove 8 through the oil injection hole 7 and the oil injection hole 7 is sealed. The lubricating oil inside the oil supply groove 8 flows out through multiple sets of oil outlet holes 9 to facilitate the flow of lubricating oil to the whole body of the tile body 1.
