Description

Technical Field

[0001] The utility model relates to the technical field of sliding bearings, in particular to a multi-support sliding bearing structure. Background Art

[0002] Sliding bearing is a bearing that works under sliding friction. Sliding bearings work smoothly, reliably and without noise. Under liquid lubrication conditions, the sliding surfaces are separated by lubricating oil without direct contact, which can greatly reduce friction loss and surface wear. The oil film also has a certain vibration absorption ability. However, the starting friction resistance is relatively large. The part of the shaft supported by the bearing is called the journal, and the part that matches the journal is called the bearing. The anti-friction material layer cast on the inner surface of the bearing to improve the friction properties of the bearing surface is called the bearing liner. The materials of the bearing liner and the bearing liner are collectively called sliding bearing materials.

[0003] For sliding bearings of long rods, multiple supporting structures are often required to keep the sliding bearings fixed. However, since the multiple supporting structures are fixed to the sliding bearings, the spacing between the supporting structures cannot be adjusted during installation, and the installation position is limited. In addition, since the oil filling hole of the sliding bearing contains air, air is easily added to the lubrication cavity during the oil filling process. The air is squeezed and compressed, which seriously affects the lubrication effect of the sliding bearing. Utility Model Content

[0004] The purpose of the utility model is to address the deficiencies in the prior art and provide a multi-support sliding bearing structure, which realizes the functions of installation in different positions and filling and exhausting through an adjustable mobile support frame structure and an exhaust hole structure, thereby solving the problem of limited installation position and affecting the lubrication effect.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a multi-support sliding bearing structure, which includes a sliding bearing body and a fixed support frame installed on the sliding bearing body, wherein the sliding bearing body is adjustable at both ends thereof and a movable support frame is installed thereon, and protrusions are fixed on both sides of the outer wall of the sliding bearing body, wherein an exhaust pipe is fixed to the outer wall of the sliding bearing body, a sealing plug is fixed to the exhaust pipe, and a bolt abutting against the protrusion is threadedly inserted into the outer wall of the movable support frame.

[0006] Preferably, a connecting portion is provided at the top end of the exhaust pipe, and the sealing plug is threadedly inserted into the connecting portion.

[0007] Furthermore, the sliding bearing body includes a fixed part connected to the fixed support frame and a rotating part slidably engaged in the fixed part, and a lubrication cavity is provided between the fixed part and the rotating part.

[0008] Furthermore, the protrusion is arranged on the outer wall of the fixing portion, and the two ends of the lubrication cavity are respectively connected to two exhaust pipes.

[0009] Furthermore, an oil filling hole is provided on the inner wall of the lubrication cavity, and a one-way valve is embedded and fixed in the oil filling hole.

[0010] Furthermore, a threaded hole connected to the oil filling hole is formed at the top of the fixed support frame, and mounting holes are formed at both ends of the fixed support frame and the movable support frame.

[0011] Furthermore, a through hole is provided at the center of the movable support frame, and positioning grooves are provided on both sides of the inner wall of the through hole, and the protrusions are fitted and inserted in the positioning grooves.

[0012] The beneficial effects of the utility model are:

[0013] (1) The utility model has movable support frames sleeved and installed on both ends of the sliding bearing body, and the raised portion of the outer wall of the sliding bearing body is inserted into the positioning groove of the inner wall of the movable support frame. After loosening the bolts, the movable support frame is moved on the sliding bearing body, thereby adjusting the position of the mounting hole. The utility model is suitable for installation and fixation at different positions. After adjustment, the bolts are tightened to make them abut against the raised portion, so that the movable support frame and the sliding bearing body are kept fixed, thereby improving the diversity of the installation position of the sliding bearing body.
