Abstract
Description
Technical Field
[0001] The utility model relates to a rotating mechanism, in particular to a bearing rotating mechanism with an oil injection protection structure. Background Art
[0002] Smooth operation of bearing rotating mechanisms is crucial. However, existing bearing rotating mechanisms often face problems such as insufficient lubrication and impurity intrusion during use. This is especially true for bearings operating in dusty environments. Over time, these impurities can infiltrate the rollers and balls of the bearings, affecting the lubrication of these rotating mechanisms. This not only impacts the efficiency and lifespan of the rotating mechanism but can also cause equipment failure. Therefore, an effective oil injection protection structure is needed to address these issues. Summary of the Invention
[0003] In view of the above situation, in order to overcome the defects of the existing technology, the purpose of the present invention is to provide a bearing rotation mechanism with an oil injection protection structure, which can achieve waterproof and dustproof, rapid oil injection and lubrication, and ensure the long-term stable operation of the bearing rotation mechanism.
[0004] To achieve the above purpose, the present invention provides the following solutions:
[0005] A bearing rotating mechanism with an oil injection protection structure includes a protective cover, a bearing seat, an O-ring, an oil injection cup, a bearing, and a rotating shaft. The bearing and the bearing seat are inserted from the bottom of the rotating shaft and are sleeved on the rotating shaft. The upper end face of the bearing is against the limiting plane of the rotating shaft, and the lower end face of the bearing is against the step plane inside the bearing seat. The protective cover is connected to the top of the bearing seat, and an O-ring is arranged between the protective cover and the protective cover. An oil injection cup is arranged on the side of the bearing seat.
[0006] Furthermore, the bearing seat is installed on the bearing and the outer end of the rotating shaft, and the side end surface of the bearing seat above the bearing is provided with an oil injection hole.
[0007] Furthermore, the protective cover is installed above the bearing seat, and an O-ring groove is provided on the lower end surface of the protective cover.
[0008] Furthermore, the oil filling cup is interference fit with the oil filling through hole on the bearing seat.
[0009] The effects of the utility model are:
[0010] The oil filling cup installed on the bearing seat can achieve rapid oil filling and lubrication, which is convenient for manual control of lubricating oil injection and stopping. The protective cover can realize waterproof and dustproof effect on the bearing, and the protection level can reach IP65. The O-ring is used to seal the protective cover and the bearing seat to prevent external dust and impurities from entering the inner cavity through the gap between the protective cover and the bearing seat and affecting the bearing operation.

[0015] like Figure 1 Figure 1 shows a bearing rotation mechanism with an oil injection protection structure, comprising a protective cover 1, a bearing seat 2, an O-ring 3, an oil filling cup 4, a bearing 5, and a rotating shaft 6. The bearing 5 and bearing seat 2 are inserted from below the rotating shaft 6 and sleeved onto the rotating shaft 6. The upper end face of the bearing 5 abuts against the limiting plane of the rotating shaft 6, and the lower end face of the bearing 5 abuts against the stepped surface within the bearing seat 2. The protective cover 1 is connected to the upper side of the bearing seat 2, with an O-ring 3 disposed between the protective cover 1 and the protective cover 1. An oil filling cup 4 is disposed on the side of the bearing seat 2.
[0016] Furthermore, the bearing seat 2 is installed on the outer end of the bearing 5 and the rotating shaft 6, and the side end surface of the bearing seat 2 located above the bearing 5 is provided with an oil injection hole 201.
[0017] Furthermore, the protective cover 1 is installed above the bearing seat 2, and an O-ring groove 101 is provided on the lower end surface of the protective cover 1.
[0018] Furthermore, the protective cover 1 is connected to the bearing seat 2 through threads, and the O-ring 3 is installed in the O-ring groove 101 to form a seal to prevent external dust and impurities from entering the inner cavity along the gap between the protective cover 1 and the bearing seat 2 and affecting the operation of the bearing 5.
