Description

Technical Field

[0001] The utility model relates to a lubrication structure for a bracket shaft of a steel slag tipping machine, which is mainly used for the transmission lubrication of the bracket shaft of the steel slag tipping machine. The utility model belongs to the technical field of steel slag tipping machines. Background Technique

[0002] During the steelmaking process, about 12% of steel slag is generated, and its main components are oxides such as CaO and MgO. Oxides belong to unstable inorganic substances. After recovering the iron element in it, as raw materials such as steel slag micro-powder, steel slag block bricks, and subgrade water-stabilized layers, it has high recycling value.

[0003] The steel slag ladle is a carrier container for shipping steel slag during the steel slag treatment process. After the steel slag ladle is filled, a special equipment is used to transport the steel slag ladle to a designated position for subsequent treatment. A common steel slag tipping machine is a device for tipping steel slag. Due to the special nature of high-temperature steel slag materials, the existing bracket shafts use grease lubrication, and there are problems such as being unable to adapt to the high-temperature working environment for a long time and difficulty in adding lubricating grease. Content of the Utility Model

[0004] The purpose of the utility model is to provide a lubrication structure for a bracket shaft of a steel slag tipping machine, and the purpose to be achieved is: to meet the need for transmission lubrication of high-temperature steel slag.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The lubrication structure for a bracket shaft of a steel slag tipping machine includes a support sleeve, a copper sleeve, a bracket shaft sleeve, a gear ring support shaft sleeve, and a bracket shaft. The characteristics are as follows: The support sleeve and the bracket shaft sleeve are sleeved on the bracket shaft, the copper sleeve is sleeved on the support sleeve, and the gear ring support shaft sleeve is sleeved on the copper sleeve; The copper sleeve is provided with a copper sleeve lubrication groove and a copper sleeve lubrication hole, and the copper sleeve lubrication hole is communicated with the copper sleeve lubrication groove; The support sleeve is provided with a support sleeve lubrication groove and a support sleeve lubrication hole, and the support sleeve lubrication groove is communicated with the support sleeve lubrication hole.

[0007] As an improvement of the utility model, the number of the copper sleeve lubrication grooves is 10 - 14, and the copper sleeve lubrication grooves are evenly distributed on the circumferential interface of the copper sleeve.

[0008] The beneficial effects after adopting the above technical solutions:

[0009] 1) A copper sleeve is provided between the support sleeve and the gear ring support shaft sleeve. The copper sleeve is provided with a copper sleeve lubrication groove and a copper sleeve lubrication hole, and a solid lubricant such as graphite or molybdenum disulfide is embedded in the copper sleeve to achieve lubrication. And because the solid lubricant is pre-embedded in the copper sleeve lubrication groove and the copper sleeve lubrication hole, a part of the lubricating particles will transfer to the friction surface between the bracket shaft and the copper sleeve, forming a relatively stable solid lubrication diaphragm, which can meet the transmission lubrication requirements of high-temperature steel slag.

[0010] 2) 10 - 14 copper sleeve lubrication grooves evenly distributed in the circumferential direction can evenly distribute the solid lubricant in the circumferential direction, avoiding the problem of insufficient local lubrication. Brief Description of the Drawings

[0023] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0024] Embodiment 1

[0025] As Figure 1 shown, the lubrication structure of the bracket shaft for the steel slag tilting machine includes a support sleeve 1, a copper sleeve 2, a bracket shaft sleeve 3, a gear ring support shaft sleeve 4, and a bracket shaft 5, where:

[0026] As Figure 1 shown, the aforementioned support sleeve 1 and the bracket shaft sleeve 3 are sleeved on the bracket shaft 5, the aforementioned copper sleeve 2 is sleeved on the support sleeve 1, and the aforementioned gear ring support shaft sleeve 4 is sleeved on the copper sleeve 2; the aforementioned copper sleeve 2 can be installed on the support sleeve 1 through bolts;

[0027] As Figures 2-3 shown, the aforementioned support sleeve 1 is provided with a support sleeve lubrication groove 101 and a support sleeve lubrication hole 102, and the support sleeve lubrication groove communicates with the support sleeve lubrication hole:

[0028] As Figures 4-6 shown, the aforementioned copper sleeve 2 is provided with a copper sleeve lubrication groove 201 and a copper sleeve lubrication hole 202, and the copper sleeve lubrication hole communicates with the copper sleeve lubrication groove;

[0029] The aforementioned gear ring support shaft sleeve 4 has a structure as Figures 7-8 shown.

[0030] The aforementioned copper sleeve 2 is preferably: a cast copper alloy, the cast copper alloy grade is ZCuSn10Pb1, and the copper alloy meets the requirements of the GB / T1176-1987 standard. Elements with self-lubricating properties such as lead and tin are preferably added during the casting process.

[0031] Preferably: as Figures 4-6 shown, the number of the aforementioned copper sleeve lubrication grooves is 10 - 14, and the copper sleeve lubrication grooves are evenly distributed on the circumferential interface of the copper sleeve. For example: 12 copper sleeve lubrication grooves are evenly distributed on the circumferential interface of the copper sleeve.

[0032] During operation, solid lubricants are embedded in the copper sleeve, such as: graphite or molybdenum disulfide, etc. The solid lubricants can be transferred to the friction surface between the bracket shaft and the copper sleeve through the copper sleeve lubrication groove 201 and the copper sleeve lubrication hole 202 to form a relatively stable solid lubrication diaphragm. In this way, subsequent manual lubricant addition is not required, and automatic lubrication is achieved. The formed uniform lubrication film not only effectively reduces material friction loss but also improves the service life of the entire structure.

[0033] The present utility model is not limited to the above embodiments, and all technical solutions formed by equivalent substitution or equivalent replacement belong to the scope protected by the present utility model.
