Description

Technical Field

[0001] The utility model relates to the technical field of shaft sleeves, in particular to a multi-angle operating shaft sleeve. Background Art

[0002] The sleeve is a sleeve on the propeller shaft or stern shaft. There are many types of sleeves, including wear-resistant sleeves, plastic sleeves, ceramic sleeves, graphite sleeves, spline sleeves, oil-free sleeves, etc. As an important component that cooperates with the shaft, it is widely used in many mechanical equipment. In moving parts, long-term friction causes wear of parts. When the gap between the shaft and the hole wears to a certain extent, the parts must be replaced. Therefore, when designing, the designer chooses materials with lower hardness and better wear resistance as sleeves or bushings, which can reduce the wear of the shaft and the seat. When the sleeve or bushing is worn to a certain extent, it can be replaced, which can save the cost of replacing the shaft or seat.

[0003] On this basis, after searching the patent website, the Chinese patent with the Chinese patent announcement number CN208778499U discloses a shaft sleeve;

[0004] It can be seen that there are shortcomings in the above patent applications: most of the existing sleeves have a relatively simple structure, and the sleeves are generally directly mounted on the outside of the shaft. When the sleeve needs to be replaced, other objects on the shaft need to be removed before replacement, which affects the use efficiency. The existing sleeves generally do not have a mechanism for adding lubricating oil to the internal shaft. After long-term use, the lubrication of the sleeve and the shaft decreases, which can easily cause wear of the sleeve and the shaft, affecting the service life.

[0005] In view of the above problems, a multi-angle operating sleeve is proposed. Utility Model Content

When the sleeve needs to be replaced, other objects on the shaft need to be removed before replacement, which affects the efficiency of use. The existing sleeves generally do not have a mechanism for adding lubricating oil to the internal shaft. After long-term use, the lubrication of the sleeve and the shaft decreases, which can easily cause wear of the sleeve and the shaft, affecting the service life.

[0029] The utility model is further described below in conjunction with embodiments.

[0030] Example 1

[0031] In order to solve the problem that most existing shaft sleeves have a relatively simple structure and are generally directly sleeved on the outside of the shaft, when the shaft sleeve needs to be replaced, other objects on the shaft need to be removed before replacement, which affects the efficiency of use. Therefore, the following solution is disclosed. For details, please refer to Figure 1-Figure 3 , one side of the placement frame 11 is rotatably connected with a toggle piece 113, a mounting opening 121 is provided on the placement box 12, and one end of the placement box 12 is slidably connected with a pulling block 122, one end of the pulling block 122 is fixedly connected with a return spring 123 and a protrusion 124, and the return spring 123 is fixedly connected to the inside of the placement box 12, one side of the toggle piece 113 is fixedly connected with a connecting rod 13, one side of the connecting rod 13 is provided with a groove 131, and the connecting rod 13 matches the through hole 112 and the mounting opening 121, and the groove 131 matches the protrusion 124. When the device needs to be installed, the right shaft sleeve body 2 is rotated away from the left shaft sleeve body 1, and the device is sleeved on the outside of the shaft to be installed. At this time, the right shaft sleeve body 2 is closed, and the placement frame 11 extends to the inside of the placement box 12. When the placement box 12 is stable, At this time, the toggle piece 113 on one side of the placement frame 11 can be rotated, so that the connecting rod 13 on one side of the toggle piece 113 can enter the interior of the installation opening 121. At this time, due to the setting of the trapezoidal surface of the protrusion 124, the connecting rod 13 will not be mechanically hindered when entering the installation opening 121 and the interior of the through hole 112. Continuing to push the toggle piece 113 can make the protrusion 124 and the groove 131 engage. At this time, the toggle piece 113 can be fixed to prevent the right shaft sleeve body 2 from rotating. When it needs to be removed, pull the pulling block 122 to make the protrusion 124 disengage from the inside of the groove 131, and then rotate the toggle piece 113 to move the connecting rod 13 out of the installation opening 121. Finally, the right shaft sleeve body 2 can be rotated, thereby achieving the effect of being able to disassemble and assemble the rotating shaft more conveniently and improving work efficiency.

[0032] Example 2

[0033] In order to solve the problem that the existing sleeves generally do not have a mechanism for filling lubricating oil on the internal shaft, after long-term use, the lubrication of the sleeve and the shaft decreases, which easily leads to wear of the sleeve and the shaft, thus affecting the service life, the following solution is disclosed. For details, please refer to Figure 1 and Figure 4 , the interior of the sliding groove 14 is also slidably connected to a transmission block 142, and the bottom of the transmission block 142 is fixedly connected to a partition 143, the partition 143 is composed of a magnetic material, the interior of the left sleeve body 1 and the right sleeve body 2 are fixedly connected to a dispersion rack 151 and an oil-absorbing sponge 152, and the oil filling port 15 is communicated with the dispersion rack 151, and the oil-absorbing sponge 152 is located below the dispersion rack 151. When the shaft is installed on the outside of the shaft, the transmission block 142 can be moved using a flat head to move the partition 143. When the partition 143 is separated from the magnet block 141, The oil filling port 15 is opened. At this time, the staff can inject the lubricating oil into the interior of the oil filling port 15, and after being diverted by the dispersion frame 151, it evenly drips on the oil absorbing sponge 152. Due to the squeezing force during installation, the lubricating oil absorbed by the oil absorbing sponge 152 can be squeezed and overflowed. At this time, the flat head can be used again to move the transmission block 142, so that the partition 143 and the magnet block 141 are magnetically attracted, and then the oil filling port 15 is closed. At this time, it can have a certain dustproof effect, realize the function of being able to add lubricating oil to the sleeve, and improve the service life of the device.

[0034] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present invention is within the protection scope of the present invention.
