Description

Shaft fixing device of underground trackless equipment with bearing end face seal

Technical Field

The utility model relates to a shaft fixing device of underground trackless equipment with a bearing end face seal, and belongs to the technical field of engineering machinery mining engineering.

Background

In underground mines, particularly metal mines, underground road conditions are poor and uneven, air humidity is high, the quantity of sand and stones on the road surface is large, in underground equipment, particularly underground trackless equipment, the operation environment is worse, and the underground trackless equipment is responsible for transportation operation of ores and rubbles in the operation process.

In addition, to underground trackless equipment, the operation operating mode is poor, and equipment transships seriously, the operation is strikeed greatly, and to some connecting shaft sleeve positions very much, the atress is big to strike frequently, often causes the damage of axial plane and contact surface after using a period, if the axial plane directly contacts with the structure, causes the damage of structure mounting hole easily, when changing the axle, the structure mounting hole maintenance degree of difficulty is big, maintains untimely accelerated mutual wearing and tearing between them.

The utility model has the following contents:

the utility model aims to overcome the defects of the prior art and provide a shaft fixing device of underground trackless equipment with a bearing end face seal.

The technical scheme provided by the utility model is as follows: a shaft fixing device of underground trackless equipment with bearing end face sealing comprises an end cover, a shaft fixing end cover, a hinged shaft and a bearing on the hinged shaft, and is characterized in that the bearing is installed in a motion hinged plate, two sides of the bearing on the hinged shaft are respectively provided with a sealing installation support, an outer ring installation groove on the outer side of the sealing installation support is provided with a V-shaped sealing ring, and an inner groove on the inner side of the sealing installation support is internally provided with a rubber sealing ring; the two sides of the sealing installation support on the hinged shaft are respectively provided with a shaft sleeve, the shaft sleeves are respectively provided with an installation plate, the installation plate on one side is connected with the end cover, the installation plate on the other side is connected with the shaft fixing end cover, and the shaft fixing end cover is connected on one side end face of the hinged shaft.

Furthermore, the articulated shaft is provided with a plurality of grease nipples and a plurality of grease channels communicated with the shaft sleeve and the bearing.

The utility model has the beneficial effects that: the utility model discloses a novel underground trackless device, wherein a seal mounting bracket is additionally arranged at a gap connected with a moving part of a shaft hinge shaft of the underground trackless device, a V-shaped seal ring is arranged on the outer side of the seal mounting bracket and used for preventing obligations such as sand and stone from entering a bearing and a shaft sleeve from the gap, and a rubber seal ring is also designed on the inner side of the seal mounting bracket and used for preventing foreign matters such as sand and stone from entering the bearing and the shaft sleeve from the shaft surface and reducing abnormal sound or device faults caused by structural member damage. In addition, the connecting shaft sleeves are designed at the two ends of the hinge shaft, and after the shaft or the shaft sleeve is abraded, only corresponding spare parts need to be replaced, so that maintenance of the mounting hole of the structural member is avoided.

Drawings

FIG. 1 is a schematic structural diagram of the present invention.

The specific implementation mode is as follows: the following detailed description of embodiments of the utility model refers to the accompanying drawings in which:

as shown in figure 1, the shaft fixing device of the underground trackless equipment with the bearing end face seal comprises a hinge shaft 13 and a bearing 7 arranged on the hinge shaft, and the bearing 7 is arranged in a mounting hole of a motion hinge plate 6. The two sides of the bearing 7 on the hinged shaft 13 are respectively provided with a sealing installation support 5, the outer side of the sealing installation support 5 is provided with an outer ring installation groove, the V-shaped sealing ring 8 is installed in the outer ring installation groove of the sealing installation support 5, and the V-shaped sealing ring 8 is used for preventing foreign matters such as sand and stones from entering the bearing 7 from the connection gap. The inner side of the seal mounting bracket 5 is provided with an inner groove, the rubber sealing ring 12 is arranged in the inner groove of the seal mounting bracket 5, and the rubber sealing ring 12 is used for preventing foreign matters such as sand and stones from entering the bearing 7 from the shaft surface. And a plurality of grease nipples 10 are provided on the hinge shaft 13 and a plurality of grease passages are processed, so that the shaft sleeve 4 and the bearing 7 can be lubricated respectively.

The both sides of sealed installation support 5 are equipped with axle sleeve 4 respectively on the articulated shaft 13, all are equipped with mounting panel 3 on the axle sleeve 4, and the mounting panel 3 of both sides welds on same structure, and the two is static relatively. The end cover 2 is fastened on the mounting plate 3 on one side through the fixing bolt 1. The outer ring mounting hole of the shaft fixing end cover 9 is fastened on the mounting plate 3 on the other side through a bolt, and the inner ring mounting hole of the shaft fixing end cover 9 is fastened on the end face of one side of the hinge shaft 13 through a bolt, so that the hinge shaft 13 is fixed through the shaft fixing cover 9 and the bolt. Meanwhile, the end cover 2 acts on the end face of the inner ring at one side of the bearing 7 through the shaft sleeve 4 and the seal mounting bracket 5 at one side; the shaft fixing end cover 9 acts on the end face of the inner ring on the other side of the bearing 7 through the shaft sleeve 4 and the seal mounting bracket 5 on the other side to fix the inner ring of the bearing 7.

It should be understood that parts of the specification not set forth in detail are well within the prior art. The above examples are only for describing the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention, and various modifications and improvements made to the technical solution of the present invention by those skilled in the art without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
