Description

Technical Field

[0001] The utility model belongs to the technical field of bearing installation, and in particular relates to an oil-free bearing which is easy to install. Background Art

[0002] Oil-free bearings are a novel lubricated bearing that combines the characteristics of metal bearings and oil-free lubricated bearings.

[0003] The traditional method for installing oil-free bearings is to place a sleeve on the upper end of the bearing to isolate the bearing, and then use a wooden hammer to gently tap the bearing to knock it into the mounting seat. However, since the sleeve is mostly solid, this method will transfer excess kinetic energy to the wooden hammer when tapping, causing the sleeve to vibrate and affecting the accuracy of installation. Therefore, an easy-to-install oil-free bearing is urgently needed to solve the above problems. Utility Model Content

[0004] The technical problem to be solved by the utility model is that when a wooden hammer strikes a sleeve, since most sleeves are solid, excess kinetic energy will be transferred to the wooden hammer, causing vibration of the sleeve and affecting the accuracy of installation.

[0005] In order to achieve the above functions, the technical solution adopted by the present invention is as follows: an oil-free bearing that is easy to install, including a mounting seat and a bearing body arranged at the upper end of the mounting seat, the mounting seat is fixedly provided with a mounting hole for the bearing body to be installed, the upper end of the bearing body is provided with a sleeve assembly to isolate the bearing body, the sleeve assembly includes a semi-hollow column clamped at the upper end of the bearing body, the lower end of the semi-hollow column is provided with a support assembly to support the bearing body, and a plurality of oil drain holes are distributed in an array on the outer wall of the bearing body.

[0006] Furthermore, an upper cover is threadedly connected to the upper end of the semi-hollow column, and a fixed block is fixed to the inner wall of the lower part of the semi-hollow column. A plurality of cylindrical grooves are distributed in an annular manner on the fixed block, and a connecting rod is provided in each cylindrical groove. The connecting rod is fixed to the fixed block, and a plurality of annular iron sheets are provided on the outer wall of the connecting rod. The annular iron sheets are used to remove the extra kinetic energy when the wooden hammer strikes.

[0007] Furthermore, the diameter of the fixing block is smaller than that of the semi-hollow column, a circular groove is formed between the semi-hollow column and the fixing block, a support column is fixed to the lower end of the bearing body, and the support column is threadedly connected to the circular groove.

[0008] Furthermore, the support assembly includes a support column fixedly connected to the lower end of the semi-hollow column, and the size of the support column is the same as the inner diameter of the bearing body.

[0009] Furthermore, an annular groove is formed between the circular groove at the lower end of the semi-hollow column and the supporting column, and a gasket ring fixedly connected to the semi-hollow column is provided in the annular groove.

[0010] Furthermore, a guide ring for guiding is provided at the lower end of the bearing body.

[0011] The beneficial effects achieved by the utility model using the above structure are as follows:

[0012] 1. A sleeve assembly is provided. Multiple annular iron sheets are provided in the cylindrical groove of the fixed block in the assembly. When the wooden hammer strikes, the excess kinetic energy will be transferred to the iron sheet, which will only cause the iron sheet to slide on the upper end of the connecting rod, thereby achieving the purpose of unloading the excess kinetic energy;

[0013] 2. A support column with the same inner diameter as the ring and a gasket at the lower end of the semi-hollow column are provided to ensure that the bearing body is installed vertically when knocking and that the upper end of the bearing body will not be bumped.

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Specific embodiment one:

[0023] refer to Figure 1 As shown, in order to achieve the above functions, the technical solution adopted by the present invention is as follows: an oil-free bearing that is easy to install, including a mounting seat 1, and a bearing body 2 arranged at the upper end of the mounting seat 1, a mounting hole fixedly opened on the mounting seat 1 for the bearing body 2 to be installed, a sleeve assembly is provided at the upper end of the bearing body 2 to isolate the bearing body 2 and to remove excess kinetic energy, the sleeve assembly includes a semi-hollow column 3 clamped at the upper end of the bearing body 2, a support assembly is provided at the lower end of the semi-hollow column 3 to support and guide the bearing body 2, and 40 oil drain holes 7 are distributed in an array on the outer wall of the bearing body 2, and each oil drain hole 7 is provided with fixed lubricating oil.

[0024] like Figure 1-5 As shown, the upper end of the semi-hollow column 3 is threadedly connected to the upper cover 4, and a fixed block 5 is fixed on the inner wall of the lower part of the semi-hollow column 3. The diameter of the fixed block 5 is smaller than that of the semi-hollow column 3. A circular groove is formed between the semi-hollow column 3 and the fixed block 5 for connecting with the support column 10 at the lower end of the semi-hollow column 3. The lower end of the bearing body 2 is fixed with a support column 10, and the support column 10 is threadedly connected to the circular groove. There are multiple cylindrical grooves distributed in an annular manner on the fixing block 5, and each cylindrical groove is provided with a connecting rod 6. The connecting rod 6 is fixedly connected to the fixing block 5. Six annular iron sheets 8 are provided on the outer wall of the connecting rod 6. The annular iron sheet 8 slides to the upper end of the connecting rod 6 by absorbing the excess kinetic energy of the wooden hammer, thereby realizing the function of unloading excess kinetic energy. Specific embodiment two:

[0026] like Figure 4 and Figure 5 As shown, the support assembly includes a support column 10 fixedly connected to the lower end of the semi-hollow column 3. The size of the support column 10 is the same as the inner diameter of the bearing body 2, ensuring that it fits perfectly with the inner diameter of the bearing body 2 and will not shake during installation. An annular groove is formed between the circular groove at the lower end of the semi-hollow column 3 and the support column 10. A rubber gasket 11 fixedly connected to the semi-hollow column 3 is provided in the annular groove to prevent direct contact between the bearing body 2 and the semi-hollow column 3. A guide ring 9 for guiding is provided at the lower end of the bearing body 2. The lower end of the guide ring is chamfered at 45 degrees to facilitate alignment with the mounting hole on the mounting seat 1.

[0027] During specific use, the user installs the bearing body 2 into the annular groove at the lower end of the semi-hollow column 3 and locks it, then installs the guide ring 9 at the lower end of the bearing body 2, aligns the guide ring 9 with the mounting hole on the mounting seat 1, and gently taps the upper cover 4 threadedly connected to the upper end of the semi-hollow column 3 with a wooden hammer. The excess kinetic energy generated by the tapping is removed through the annular iron sheet 8 on the connecting rod 6 therein, thereby ensuring that the bearing body 2 will not shake and facilitating installation. At the same time, the upper cover 4 can be unscrewed to replace different numbers of annular iron sheets 8 until the bearing body 2 is completely knocked in, and then pulled to release the connection with the semi-hollow column 3 to complete the installation process of the entire device.
