Description

Technical Field

[0001] The utility model belongs to the technical field of bearing refueling, and particularly relates to a quick-installation positioning refueling joint for a bearing seat. Background Art

[0002] A bearing is an important component in mechanical equipment. Bearings can be divided into two categories: rolling bearings and sliding bearings. The daily maintenance and upkeep of bearings include lubrication, cleaning, installation and disassembly, operation monitoring, storage, and protection. The reasons for bearing wear include peeling, burning, crack defects, cage damage, etc. The treatment methods are to check the machining accuracy of the shaft and bearing housing, check the type of lubricant to ensure the injection volume, set an appropriate interference fit, and check the material, etc.

[0003] Among them, a conveyor drum bearing is a type of bearing. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotational accuracy.

[0004] Since the conveyor drum bearings of coal conveying equipment are all hoisted at a height of more than 5 meters, ordinary oil guns cannot refuel and maintain the conveyor drum bearings. At the same time, due to the small aperture of the grease nipple of the oil gun, it is impossible to work with a snap-type manual oil gun in special environments, and it will have a greater impact on the coal conveying equipment if the conveyor drum bearings of the coal conveying equipment cannot be refueled. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art and propose a quick-installation positioning refueling joint for a bearing seat, which can normally inject grease into the bearing seats of rotating equipment at any height, in a vertical installation or a hoisted state, improve the working efficiency of bearing maintenance, and thereby reduce the probability of mechanical damage.

[0021] The following further describes the present utility model in conjunction with the accompanying drawings.

[0022] A quick-installation positioning grease filling joint for a bearing housing acts on the grease filling port 2 of the bearing housing and includes a positioning grease filling joint, a support rod, and a grease pipe 11. Among them, the oil inlet end of the positioning grease filling joint is connected to the grease pipe by a thread. The grease pipe is used to transmit grease, and the positioning grease filling joint is used to inject the grease in the grease pipe into the grease filling port of the bearing housing. The support rod is installed at the oil outlet end of the positioning grease filling joint and is used to support the docking of the positioning grease filling joint with the grease filling port of the bearing housing.

[0023] The grease filling port of the bearing housing is installed on the bearing housing 1. The grease filling port of the bearing housing is coaxially sleeved with an annular magnet 3. One end of the annular magnet is fixed to the bearing housing, and the other end of the annular magnet is provided with a conical guide.

[0024] The positioning grease filling joint includes a positioning magnet 4, a slide rail 5, and a grease filling rod 6. Among them, the slide rail is installed around the oil outlet end of the grease filling rod. The positioning magnet is installed on the slide rail and is slidably connected to the oil outlet end of the grease filling rod.

[0025] The positioning magnet is an annular magnet and is coaxially and slidably connected around the grease filling rod.

[0026] The support rod includes a positioning sleeve 7, a telescopic rod 8, and a pulley 9. Among them, the positioning sleeve is installed at the supporting end of the telescopic rod. The telescopic rod is used to lift the positioning grease filling joint to different heights. The positioning sleeve is sleeved on the positioning magnet and is used for the cooperation of the positioning magnet and the annular magnet. The pulley is installed on the side wall of the telescopic rod.

[0027] The positioning grease filling joint further includes a connecting line 10. One end of the connecting line is fixed at the oil inlet of the grease filling rod, and the other end of the connecting line passes through the pulley on the side wall of the telescopic rod. The connecting line is used to pull the grease filling rod so that the oil outlet end of the grease filling rod is inserted into the grease filling port of the bearing housing.

[0028] The working principle of the present utility model is as follows:

[0029] The staff sets the positioning sleeve on the telescopic rod on the positioning magnet. At the same time, the connecting wire at the oil inlet end of the positioning fueling joint is passed through the pulley, and the length of the telescopic rod is adjusted according to the bearing housing that needs to be refueled. The positioning fueling joint is placed in front of the corresponding fueling port of the bearing housing through the telescopic rod. The staff further moves the positioning fueling joint to insert the ring magnet into the positioning sleeve. Since the other end of the ring magnet is provided with a conical guide, the insertion process of the ring magnet is relatively smooth. At the same time, the ring magnet and the positioning magnet attract each other, and the positioning sleeve limits the attraction position of the ring magnet and the positioning magnet to prevent the ring magnet and the positioning magnet from being unable to be coaxially aligned. At this time, the staff pulls the connecting wire passing through the pulley. Since the positioning magnet is coaxially slidably connected around the fueling rod, the fueling rod slides according to the force direction of the connecting wire, and then the oil outlet end of the fueling rod is inserted into the fueling port of the bearing housing, as Figure 4 shown, thus completing the quick positioning of the present utility model.

[0030] It should be emphasized that the embodiments described in the present utility model are illustrative rather than restrictive. Therefore, the present utility model includes but is not limited to the embodiments described in the specific embodiments. Any other embodiments obtained by those skilled in the art according to the technical solutions of the present utility model also belong to the scope of protection of the present utility model.
