Description

Technical Field

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

[0002] The sleeve is a cylindrical mechanical part that is sleeved on the rotating shaft and is a component of the sliding bearing. Generally speaking, the sleeve and the bearing seat adopt an interference fit, and the sleeve and the shaft adopt a clearance fit. The existing sleeve does not have a lubrication structure, so the inner wall of the sleeve is prone to large friction after long-term use, and the inner wall of the sleeve is prone to wear after long-term use. Therefore, we propose a wear-resistant sleeve. Utility Model Content

[0003] The purpose of the utility model is to provide a wear-resistant shaft sleeve to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wear-resistant sleeve, comprising a sleeve, an oil chamber is provided inside the sleeve, an outer wall of the sleeve is provided with a refueling port connected to the oil chamber, a cavity is provided inside the sleeve, a plurality of groups of oil outlet holes are provided on the inner wall of the sleeve, an oil guide rope is provided in the cavity, one end of the oil guide rope passes through the left side wall of the cavity and is connected to the inner wall of the oil chamber, and the other end of the oil guide rope is arranged in the oil outlet hole.

[0005] Furthermore, the oil guide rope is made of cotton fiber material.

[0006] Furthermore, the oil outlet hole is communicated with the cavity.

[0007] Furthermore, a plurality of groups of oil outlet holes are distributed in a ring array on the inner wall of the sleeve.

[0008] Furthermore, an inner wall of the fuel filling port is provided with an internal thread, and a sealing bolt matching the internal thread is provided in the fuel filling port.

[0009] Furthermore, the oil chamber is arranged in a ring shape.

[0010] Furthermore, the cavity is arranged in a ring shape.

[0011] Compared with the prior art, the utility model has the beneficial effect that the inner wall of the sleeve can be lubricated with oil by the cooperation of the oil outlet hole, the sealing bolt, the oil filling port, the oil chamber, the oil guide rope and the cavity, thereby avoiding the wear of the inner wall of the sleeve caused by large friction.

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Embodiment 1:

[0018] See also Figure 1-3 The utility model provides a technical solution: a wear-resistant sleeve, including a sleeve 1, an oil chamber 5 is provided inside the sleeve 1, the oil chamber 5 is arranged in a ring shape, a refueling port 4 connected to the oil chamber 5 is provided on the outer wall of the sleeve 1, an internal thread is provided on the inner wall of the refueling port 4, a sealing bolt 3 matching the internal thread is provided in the refueling port 4, a cavity 7 is provided inside the sleeve 1, the cavity 7 is arranged in a ring shape, a plurality of groups of oil outlet holes 2 are provided on the inner wall of the sleeve 1, the oil outlet holes 2 are connected to the cavity 7, and the plurality of groups of oil outlet holes 2 are distributed in a ring array on the inner wall of the sleeve 1, an oil guide rope 6 is provided in the cavity 7, one end of the oil guide rope 6 passes through the left side wall of the cavity 7 and is connected to the inner wall of the oil chamber 5, and the other end of the oil guide rope 6 is arranged in the oil outlet hole 2, and the oil guide rope 6 is made of cotton fiber material.

[0019] Working principle: Use the refueling port 4 to add the lubricating oil into the oil chamber 5, then turn the sealing bolt 3 to seal the refueling port 4, and the lubricating oil flows into the oil outlet 2 through the oil guide rope 6. The oil outlet 2 can seep out the lubricating oil, and the lubricating oil can lubricate the inner wall of the sleeve 1 to avoid wear caused by large friction on the inner wall of the sleeve 1.
